2025’s Top Smartwatches & Fitness Trackers – Latest Innovations and 2026 Trends

A Smarter, Healthier Wearable Landscape

Smartwatches and fitness trackers have never been more advanced or popular. In 2025, wearables from Apple, Samsung, Google, Fitbit, Garmin, Huawei, Amazfit, Xiaomi and others are packed with sleek designs, vibrant displays, and an array of health sensors (heart rate, ECG, SpO₂, sleep, even skin temperature). These devices double as fitness coaches and smartphone companions, delivering notifications, music control, GPS navigation, and more – all on your wrist. Battery life ranges from a day to several weeks depending on the model, and most wearables are water-resistant and built to handle real life. Below we compare the latest and most popular smartwatches and trackers of 2025 – and peek at what’s coming in 2026 – covering design, displays, health/fitness features, smart capabilities, battery, compatibility, durability, pricing, and notable innovations. We’ll also include expert insights and quotes from reviews to give you the full picture.

Smartwatch & Fitness Tracker Trends in 2025

Wearable tech in 2025 is driven by health tracking and AI-powered insights. According to TechInsights, “smartwatches are driving the wearable market with innovations in AI, health monitoring, and connectivity,” as brands like Apple, Samsung and Garmin push the boundaries of wrist tech. Advanced sensors (ECG heart rhythm, blood oxygen SpO₂, sleep stages, etc.) have become common even on affordable devices, “making wearables indispensable for health-conscious consumers”. Generative AI integration is a huge trend – wearables are evolving from basic data loggers into personalized wellness coaches. “Generative AI is transforming wearables by enabling advanced features like health scoring, personalized recommendations, and conversational virtual assistants,” effectively turning raw data into actionable coaching. Many 2025 watches can analyze your habits and offer tailored tips – for example, Samsung’s latest watches use Galaxy AI to interpret your sleep, activity and stress and suggest improvements, and Google’s Fitbit platform uses AI for things like personalized sleep schedules.

Another big trend is new form factors. Traditional fitness bands remain popular, but we’re also seeing smart rings and other wearables emerge. In fact, Samsung has introduced a Galaxy Ring in 2025, a titanium smart ring that packs heart-rate, motion, and skin temperature sensors. It integrates with Samsung Health and uses AI for real-time analysis and personalized wellness tips, all with a 7-day battery in a tiny ring form. (The Galaxy Ring is launching in select markets at a premium price point, showing that major brands see a future in ring-style trackers.) Meanwhile, traditional fitness bands are getting smarter – even budget trackers offer color AMOLED screens and advanced metrics – and high-end smartwatches are adding more rugged and medical-grade capabilities. Below, we dive into each major brand’s standout devices.

Apple: Watch Series 10 (2024) and the Road to Series 11 (2025)

Apple’s wearables continue to set standards for design and app ecosystems. The Apple Watch Series 10, released in late 2024, refined Apple’s iconic square design with a slightly larger always-on OLED display and a thinner case. However, many felt it was an incremental update: “the Apple Watch 10 turned out to be more or less identical to every Apple Watch sold over the last few years. The display was just a tad larger and the body slightly thinner, but overall it was very similar to the Series 9” macworld.com. Apple stuck to the proven formula – a bright Retina display (~1.9”), sleek aluminum or steel build, and 18-hour battery life – without any radical redesign. On the health front, Series 10 (like Series 9) offers robust fitness tracking with continuous heart-rate monitoring, ECG capability (FDA-cleared for atrial fibrillation alerts), blood oxygen saturation (SpO₂) measurements, sleep stages, and skin temperature sensing at night (used for cycle tracking). It runs watchOS, giving you the richest app selection (from fitness and music apps to smart home control) and seamless iPhone integration – though notably Apple Watch only works with iPhone, not Android. Pricing for Series 10 started around $399, with higher-end stainless steel or Hermès editions costing more.

Fans were a bit underwhelmed that Apple didn’t celebrate the Watch’s 10th anniversary with something revolutionary (the Apple Watch launched in 2015). The good news: 2025’s Apple Watch Series 11 is expected to bring more substantial innovations. Apple skipped updating the Apple Watch Ultra or SE in 2024 macworld.com, which hints that fall 2025 will be a big refresh across the lineup. Rumors and leaks (per Macworld and Bloomberg) suggest Series 11 will finally deliver long-awaited features macworld.com: possibly a new “Watch X” design to mark the decade, with a slimmer, flatter form, a new magnetic band attachment (for a larger battery), and perhaps a shift to a micro-LED display for a brighter, more efficient screen. (Apple has been working on micro-LED, but reports say high costs caused delays – the tech “won’t be as soon as we first thought”. If not in 2025, a micro-LED Apple Watch could land in 2026 or 2027, bringing OLED-like vibrancy with better battery life and no burn-in.) In terms of sensors, truly groundbreaking capabilities like noninvasive blood glucose or blood pressure are still in development – Apple is trying to get features like blood pressure and blood sugar monitoring onto the Watch, but these likely won’t arrive in 2025. Instead, Apple is focusing on AI and software improvements. WatchOS updates in 2025 (watchOS 12 and 13) are integrating more machine learning: one upcoming feature is a “Workout Buddy” that analyzes your fitness metrics to create personalized insights and pep talks. Apple is also reportedly working on on-device Siri/AI integration (tentatively called “Apple Intelligence”) to enable smarter coaching and assistance on the watch. For example, your watch and iPhone could jointly use AI to transcribe conversations in real time for accessibility, translate speech on the fly, or adjust notifications intelligently based on context. Many of these AI-driven features will come with watchOS 2026 and be available on recent models, but Apple may keep a couple as Series 11 exclusives to showcase its newest S-series chip’s capabilities.

On the health side, Apple Watch remains one of few wearables with FDA-cleared ECG and irregular rhythm notifications. Series 10/11 also offer Low/High heart rate alerts, cardio fitness (VO₂max) estimates, fall detection, cycle tracking with temp insights, and blood oxygen monitoring for wellness (not medical use). Sleep tracking on Apple Watch has improved (now logging sleep stages and respiratory rate), though it’s still less granular than some rivals. Apple’s strength is how all these metrics integrate into the iPhone’s Health app and features like fitness sharing, trends, and now mental health check-ins. Battery life is the trade-off for Apple’s rich features: standard models last ~18 hours per charge (basically one full day). You’ll be charging nightly unless you use the low-power mode (which can stretch it to ~2 days by limiting features). The rugged Apple Watch Ultra model (with a 49mm titanium case, bigger battery, dual-frequency GPS, and 100m water resistance for diving) offers 36 hours standard, or up to 60 hours in low-power settings. Apple skipped an Ultra update in 2024 macworld.com, so an Apple Watch Ultra 3 with a faster chip and possibly micro-LED display could debut alongside Series 11 in late 2025 macworld.com macworld.com. Expect the Ultra 3 to remain ~$799. Meanwhile the affordable Apple Watch SE (last refreshed in 2022) might get a 2025 update as well – rumors suggested a redesigned plastic SE was planned, though production issues put that in jeopardy macworld.com. For now, the $249 SE 2 is Apple’s budget pick (no always-on display, no ECG or SpO₂ sensor, but all core fitness/smartwatch functions).

Design & durability: Apple Watches have a premium build (aluminum or steel, sapphire glass on steel models, ceramic back) and are water resistant to 50m (Series) or 100m (Ultra with EN13319 dive certification). The Series models favor a modern square-with-rounded-corners look that maximizes screen area; customization is high thanks to Apple’s vast watch band ecosystem. OS compatibility: requires an iPhone (iPhone 8 or later for Series 10/11). Price: Series 10 started at $399 for 41mm GPS aluminum, $429 for 45mm; add $100 for cellular versions. Stainless steel cases start around $699. Apple’s tight hardware-software integration and polished user experience make the Watch a top choice for iPhone users, while 2025 should finally bring some of the exciting innovations (AI coaching, new designs) that fans have been waiting for.

Samsung: Galaxy Watch 7 & 8 – Android Powerhouses and a New Galaxy Ring

Samsung is Apple’s biggest rival in smartwatches, and in 2025 it’s doubling down on both high-end watches and new wearables like rings. The Samsung Galaxy Watch 7 launched in mid-2024 and earned praise for its feature-packed Wear OS experience. Like many recent smartwatches, the upgrades over its predecessor (Watch 6) were modest: “Samsung isn’t ringing the design changes with the Galaxy Watch 7, with its latest iteration looking virtually identical to last year’s Galaxy Watch 6”. The Watch 7 stuck to a round AMOLED display (1.3″ on the 40mm, 1.5″ on 44mm) with optional always-on, and it brought back a rotating bezel in a new form – Samsung introduced a premium Galaxy Watch Ultra (2024) model to replace the previous “Classic.” The Galaxy Watch Ultra (1st gen) has a robust titanium design with a large 47mm screen, MIL-STD durability, 10ATM water resistance, and that beloved physical rotating bezel, priced around $649. This Ultra catered to those wanting a bigger battery and more rugged build (much like Apple’s Ultra). For the standard Watch 7, Samsung focused on improving accuracy and performance. It debuted a faster 3nm Exynos W930 chip and a redesigned BioActive sensor array with 13 LEDs for more precise health tracking. According to Wareable, “Samsung’s mid-range smartwatch…focuses on being a more accurate and insightful smartwatch than its previous one… with a faster new chip, a redesigned BioActive sensor, and the addition of dual-frequency GNSS”. New health and fitness insights were a selling point, thanks to Samsung’s enhanced algorithms (e.g. improved sleep coaching and heart-rate zone training). However, one thing Samsung didn’t improve was battery life – tests showed the Galaxy Watch 7 still lasts about 1–2 days per charge, similar to Watch 6. As Wareable noted, “it’s just a shame it couldn’t ramp things up in the battery department when rivals have shown what can be done”. The Watch 7 remains one of the best options for Android users, but heavy users may need to top it up daily.

Moving into 2025, Samsung wasted no time iterating. The Galaxy Watch 8 series was officially unveiled in July 2025. Samsung slightly tweaked its lineup naming: the Galaxy Watch 8 comes in the usual two sizes (now 41mm and 45mm) and the Galaxy Watch 8 Classic returns (a single 46mm model with the rotating bezel and more premium stainless build). Interestingly, Samsung treated the 2024 Ultra as a one-off for now – instead of a brand-new Ultra 2, the 2025 release gave the Galaxy Watch Ultra (2024) a minor refresh (a new titanium color and double the storage) phonearena.com. So effectively, the Watch 8 Classic fills the high-end slot this cycle.

What’s new in Galaxy Watch 8? The design language got a subtle update inspired by last year’s Ultra: both Watch 8 and 8 Classic use a “circle-in-a-square” cushion shape (squared-off watch body with round display) for a rugged yet stylish look. The Watch 8 is also about 11% thinner than the Watch 7, making it sleeker on the wrist. More importantly, Samsung leaned heavily into new health features powered by AI. The Watch 8 series introduced a unique sensor metric called “Antioxidant Index,” which measures carotenoid levels in your skin to assess your diet’s antioxidant intake – a novel metric tied to long-term health and longevity. It’s essentially checking your skin for signs of a healthy diet (high in fruits/veggies) and gives you a score. Another new addition is “Bedtime Guidance,” which analyzes your circadian rhythm and daily fatigue to recommend the ideal time to sleep. Samsung also enhanced many existing features: Sleep Coaching is smarter, with Sleep Consistency tracking and even assigning you a sleep symbol (animal) to categorize your patterns. The Watch 8 continues to offer comprehensive sleep stage tracking, now with improved accuracy and a new Sleep Mode that mutes notifications more intelligently at night. Fitness features got a boost too – there’s a new AI Running Coach that assesses your running form and creates personalized training plans, plus personalized heart rate zones for optimal training and automatic Track Run lap tracking. Samsung’s hallmark sensor array still includes ECG (for atrial fibrillation checks) and PPG-based blood pressure monitoring (in regions where available, user-calibration required), as well as SpO₂, continuous heart rate, stress (via HRV), and even skin temperature tracking (used for advanced cycle tracking similar to Apple). Notably, many of these capabilities benefit from Samsung’s Galaxy AI integration with the new watches. PhoneArena reports that with Watch 8, “Samsung brought Gemini (Google’s AI) integration on board – you can now issue voice commands through Google’s AI agent and control different apps”. The watches run Wear OS 4 with One UI Watch on top, so you have Google Assistant, Play Store apps, and Samsung’s own apps in harmony.

Despite adding features, Samsung did bump the battery capacity slightly (e.g. ~325 mAh on 41mm, 435 mAh on 45mm), but real-world battery life remains ~2 days at best (the bright always-on AMOLED and constant sensors limit longevity). The Watch 8’s display is very bright (Samsung uses a high-res Super AMOLED with up to 1,500+ nits brightness, great outdoors). Durability: 5ATM + IP68 water resistant (safe for swimming to 50m) and MIL-STD-810H rated for shock, heat, etc. The Watch 8 Classic with its stainless steel body and rotating bezel is especially robust, while the standard Watch 8 aluminum model is lightweight and sporty. Both are compatible with standard 20mm straps. Compatibility: Samsung watches work with any Android (Android 10+), but some features (ECG, blood pressure) require a Samsung phone with the Samsung Health Monitor app due to regulatory locks. There’s no iPhone support. Pricing: Samsung did raise prices – the Galaxy Watch 8 (Bluetooth) starts at $349 (40mm) and $379 (45mm), about $50 more than last gen. The Watch 8 Classic 46mm starts at $499 (BT). LTE adds ~$50. Despite the hike, you’re getting one of the most feature-rich smartwatches available for Android.

Finally, Samsung made waves in 2025 with its Galaxy Ring (as mentioned above). This ring is an alternative or companion to a smartwatch, aimed at advanced sleep and health tracking without a screen. It packs an optical heart sensor, temperature sensor, and accelerometer into a ring form, and boasts “remarkable battery life of up to seven days”in a water-resistant titanium build. The Galaxy Ring uses those sensors to deliver detailed sleep scores, readiness (energy) scores, and AI-driven wellness tips via the Samsung Health app. For example, it can automatically log your walks/runs and give AI coaching messages, or for women, leverage temperature data for cycle tracking. It launched in Malaysia at ~RM2,099 (≈ $450) as an early access program, with broader availability likely in 2026. This signals Samsung’s commitment to leading in wearable health tech – even beyond the wrist.

In summary, Samsung’s 2025 offerings provide premium build and features for Android users: gorgeous AMOLED displays, holistic health tracking (from ECG to body composition to new diet and sleep metrics), Google-powered smarts, and now even a ring option. The ecosystem of apps (thanks to Wear OS) has grown, and Samsung’s partnership with Google means you’re not stuck with Bixby (you can use Assistant). If you have a newer Samsung Galaxy phone, these watches integrate especially well (syncing workouts, enabling all sensors). For 2026, expect possibly a Galaxy Watch 9late in the year, and maybe a true Galaxy Watch Ultra 2. Also, Samsung’s expansion into rings could push Apple and others to consider similar form factors or at least ramp up their sleep and recovery features to compete.

Google Pixel Watch & Fitbit: Blending Smarts with Fitness

Google’s approach to wearables has two prongs: the Pixel Watch line (premium smartwatches running Wear OS) and Fitbit fitness trackers (which Google acquired and is now integrating tightly). In 2025, these two have effectively merged in spirit – the Pixel Watch is now the torchbearer for Fitbit’s vision on a smartwatch. In fact, Google confirmed it “will no longer produce Fitbit smartwatches, officially ending…the Versa and Sense lineups,” focusing on Pixel Watches for full smartwatch experiences. Instead, Fitbit contributes its expertise in fitness tracking and health algorithms to both Pixel watches and dedicated trackers like the Charge series.

Google Pixel Watch 3 (2024 model) is the latest as of early 2025. This watch corrected many shortcomings of the first-gen Pixel Watch. It features a larger, brighter display (the Pixel Watch 3 comes in a new 45mm size option, with a 1.5-inch OLED that can hit up to 2,000 nits peak – double the prior model, making it very easy to read even in sunlight). Google switched the screen to an LTPO panel with adaptive 1–60Hz refresh rate, enabling an always-on display that can drop to 1 nit brightness to save power. Despite the bigger screen, the design remains sleek and minimalist – a circular domed glass face with black bezels (much reduced in the new model, about 40% larger usable screen than Pixel Watch 2). The Pixel Watch 3 uses the Snapdragon W5 Gen1 chip (a modern 4nm SoC) paired with a Cortex-M33 coprocessor. Google leveraged this coprocessor heavily: “the Pixel Watch 3 is using Qualcomm’s Snapdragon W5, while the Cortex-M33 co-processor…handles the always-on display, connectivity, health tracking, and ML algorithms” so that the main processor sleeps unless needed. This means even with added features, battery life stays around 24 hours (with always-on enabled) on both the 41mm and 45mm – not an improvement over last gen, but Google managed to maintain a full day use despite a larger, much brighter screen 9to5google.com. Reviewers note Google is essentially prioritizing “smarts” over multi-day battery: “Overall, with the Pixel Watch 3, Google is prioritizing smarts and other helpful features over extended battery life…targeting a full day of usage is in line with most other smartwatches” 9to5google.com.

Where the Pixel Watch 3 truly shines is health and safety features, thanks to deep Fitbit integration. It includes Fitbit’s 24/7 heart-rate tracking (with a new multi-path sensor for better accuracy during workouts), built-in GPS, automatic workout detection, sleep tracking with profiles, and even stress tracking via an EDA (electrodermal activity) sensorinherited from the Fitbit Sense line. Notably, Pixel Watch 3 introduced a groundbreaking feature: Loss of Pulse Detection. This uses the optical heart sensor and other signals to detect if the wearer might be experiencing a cardiac arrest or other event where the heart stops. If it detects no pulse and the user doesn’t respond to a prompt, the watch will call emergency services with your location – potentially lifesaving for situations like sudden cardiac arrest. “This is a new feature for any wearable…if there’s no response or motion, the Pixel Watch 3 will place a call to emergency services with your location and context”. It launched first in select European countries in late 2024 and is pending regulatory approval elsewhere (not yet FDA-cleared in the US). Pixel Watch 3 also offers an ECG app (on-demand readings for Afib detection, like Fitbit Sense had) and can alert you to irregular heart rhythms in the background. You get the usual Fitbit metrics: daily “Active Zone Minutes,” stress management score, sleep score, and the new “Readiness Score” (which gauges how rested/recovered you are each day, similar to Garmin’s Body Battery or Oura’s readiness). Google even added Ultra-Wideband (UWB) to the Pixel Watch 3, enabling precise phone-finding and smart home interactions. On Wear OS 4, the watch benefits from Google Assistant on-wrist, Google Maps turn-by-turn navigation (even offline), Google Wallet payments, and a growing ecosystem of third-party apps (Spotify, Strava, etc.). It’s basically the best of Fitbit combined with the best of Google.

Looking ahead, the Pixel Watch 4 is expected in late 2025 (likely alongside the Pixel 10 phone). Rumors suggest it may finally bring a newer chipset (possibly Qualcomm’s next-gen W5+ or Google’s own Tensor chip for wearables) to improve battery life and performance. AndroidCentral notes wishlist items like a bigger battery and even more seamless AI features (the codename “Gemini” AI for Assistant might bring next-gen voice capabilities). For now, Pixel Watch 3 is a strong choice, especially for Android users who value deep health tracking. It’s compatible with any Android phone (Android 9+), and unlike Samsung, Google doesn’t gate features – ECG works on any Android with the Fitbit app.

On the Fitbit side, since Google’s acquisition, there’s been a shift. 2025 confirmed that Fitbit’s own smartwatches (Sense, Versa) are discontinued. Instead, Google wants those users to transition to Pixel Watch for a smartwatch experience. Fitbit’s focus is now on dedicated fitness trackers – which it continues to refresh – and on powering the health features in Google’s wearables. The latest and most advanced Fitbit tracker is the Fitbit Charge 6, released in late 2023. The Charge 6 is a slim band with a 1.04″ OLED touch display and up to 7 days battery life. Impressively, it brings some smartwatch-like features into a band: it’s “the only fitness tracker with Google built in”, including YouTube Music controls, Google Maps directions, and Google Wallet payments on the wrist. It also has Fitbit’s most accurate heart-rate sensor yet – “up to 60% more accurate during vigorous exercise” than previous models – and it retains advanced wellness sensors: a multipurpose electrical sensor that supports ECG and EDA (electrodermal activity) scans. Yes, the Charge 6 can take an ECG reading for atrial fibrillation assessment (via the metal sides of the tracker) and also perform EDA scans to gauge stress response by measuring sweat-induced skin conductivity changes. This is a phenomenal amount of tech in a $160 band. Additionally, Charge 6 has built-in GPS for phone-free tracking of runs/rides, continuous SpO₂ monitoring during sleep, skin temperature variation tracking at night, and all-day atrial fibrillation monitoring via the PPG (Fitbit’s FDA-cleared feature for passive Afib alerts). Essentially, Fitbit poured many features of its higher-end Sense watch into the Charge 6. The tracker also has a physical side button (making a return for better usability) and improved haptic feedback. It’s water-resistant to 50m and works with both Android and iOS (Fitbit devices support both platforms equally). Fitbit’s other trackers include the Inspire 3 (basic, screenless band for steps/sleep) and the Luxe (fashion-oriented band), but no updates have come for those since 2022. Rumor has it Fitbit might release a Charge 7 or Luxe 2 in 2025/26 with minor upgrades like bigger displays or new sensors, but nothing official yet. One thing to keep in mind: Google is integrating Fitbit accounts into Google accounts, and some older community features of Fitbit are being phased out as the platform merges with Google’s. However, the Fitbit app and subscription (Fitbit Premium) remain central to interpreting your data on both Pixel Watch and Fitbit trackers, providing advanced insights like Daily Readiness, sleep animal profiles, long-term health trends, and more.

In summary, Google’s wearable strategy gives consumers choices: if you want a full smartwatch with apps and a vibrant display, Pixel Watch (starting ~$349) is the way to go, packing all of Fitbit’s health features plus Google’s smarts. If you prefer a lightweight fitness band focused purely on health tracking and long battery, Fitbit Charge 6 ( ~$159) is an excellent choice, essentially a “Pixel Band.” Both leverage Fitbit’s platform, so your data (steps, heart, sleep, etc.) feed into the same ecosystem, and you can even have a Pixel Watch and a Fitbit tracker on the same account (for example, some people wear a lighter tracker to sleep and a smartwatch by day – all your stats aggregate in Fitbit app). Compatibility is broad (Android or iOS for Fitbit devices; Pixel Watch requires Android). Looking to 2026, expect Google to continue refining AI coaching – the Personalized Sleep Schedule and other Fitbit Labs experiments hint at watches that might proactively warn you of health issues or optimally schedule your workouts via AI. Also, by 2026 Google might introduce Pixel Watch 5 with further battery gains and more seamless integration with other Google hardware (imagine your Pixel Watch acting as a key for your Pixel Tablet or unlocking your car via UWB). For now, Google and Fitbit have successfully combined strengths to challenge Apple and Samsung in the wearable arena.

Garmin: Fenix 8 and the King of Battery Life & Outdoors

Garmin may not have the general-purpose appeal of Apple or Samsung, but for fitness enthusiasts, adventurers, and athletes, Garmin’s watches are the gold standard. In 2025, Garmin’s lineup is led by the Fenix 8, a premium multisport GPS smartwatch that showcases Garmin’s latest tech. The Fenix series is known for rugged design, long battery, and ultra-advanced tracking for running, cycling, hiking, swimming, golf – you name it. The Garmin Fenix 8 (released summer 2025) did something new: it comes in two display variants – a classic memory-in-pixel transflective display (which can last weeks per charge), and an AMOLED touchscreen option for those who want a brighter, more modern look (similar to Garmin’s Epix series). The Fenix 8 also introduced voice capabilities for the first time in a Fenix. It has a built-in microphone and speaker, enabling phone calls from your wrist (via Bluetooth pairing) and voice assistant access (Siri/Google Assistant from your phone). This matches features Garmin had added to its Venu 3 and Forerunner 265 Music, but bringing it to the Fenix line is big – you can be on top of a mountain and still take a call or dictate a text if your phone is nearby (satellite phones aside!). Garmin even added neat touches like geo-tagged voice notes – you can record voice memos that tag your GPS location (useful for marking points on a hike) – and voice commands to control certain watch functions hands-free.

The Fenix 8 comes in one case size for now (51mm) for the MIP version and slightly smaller for AMOLED, each with options for premium materials (standard has fiber-reinforced polymer with stainless steel bezel; there’s also a lighter titanium model). It’s a beast of a watch physically – built to military-grade standards, with 10 ATM water resistance(100m) and tested against thermal shock, drops, etc. Uniquely, Fenix 8 is rated for recreational scuba diving up to 40m and includes a depth gauge and dive modes – essentially making it a dive computer like the Descent series. It even has leak-proof buttons to prevent water ingress at depth. For outdoors, it retains the popular LED flashlight built into the watch body (extremely handy for camping or nighttime runs).

Battery life on Fenix 8 is staggering. With the transflective display model, you can get “29–48 days in smartwatch mode” (i.e., daily use with notifications, etc.) on a single charge. Even using full GPS tracking, it can last 50–60 hours continuously with highest accuracy (and much longer with battery saver or expedition modes). The AMOLED version, while more power-hungry, is optimized to still give around 16 days in smartwatch mode (7 days if you keep always-on display) – far beyond most AMOLED competitors – thanks to its huge battery and Garmin’s efficient internals. Garmin also offers solar-charging editions on some models, although with AMOLED the benefit is limited (solar is more useful on transflective screens). Suffice to say, if you hate charging frequently, Garmin has you covered.

When it comes to fitness and health tracking, Garmin is heavy on metrics and somewhat conservative on medical features. New in 2025, Garmin upgraded to its Elevate Gen5 heart-rate sensor on the Fenix 8, improving accuracy for heart rate and HRV tracking. Garmin does now include an ECG app on a couple models (the Venu 2 Plus had a trial ECG feature cleared by FDA), but the Fenix 8 notably does not have ECG – Garmin seems to keep ECG to its lifestyle watches for now. Instead, Fenix focuses on performance metrics. It has full-day health monitoring (continuous heart rate, stress, respiration, blood oxygen, and Body Battery – a Garmin metric that combines stress, rest, and activity to show energy reserves). It tracks over 100 activity types, from standard running/cycling/swimming to skiing, surfing, strength, climbing, yoga, and more. It supports mapping (topographic, ski maps, golf courses) – with 32 GB storage, you can have offline maps on your wrist. Fenix 8 introduced new SatIQ technology and multiband GNSS across all models, meaning you get extremely accurate GPS even in city downtowns or dense forests by dynamically adapting GPS mode. This was in Fenix 7 Sapphire before, now it’s standard. The watch also offers advanced training tools: Training Readiness (which tells you each morning how prepared your body is for a workout, based on sleep, recovery, etc.), HRV Status, Training Load and Recovery Time, Stamina (real-time endurance gauge during a workout), and personalized workout suggestions. New strength training profiles can track detailed muscle groups worked, and hill score and endurance score features were added for runners in 2023 and carried forward. Essentially, if there’s a performance metric out there, Garmin either has it or is working on it. Garmin’s ethos is more about fitness and adventure than about monitoring for atrial fibrillation or detecting illness (though they do have abnormal heart-rate alerts and will log health stats). For example, Garmin will tell you your VO₂ max for trail running versus road running, your estimated race finish times, and even your “Body Battery”, but it won’t (yet) do things like spot Afib or do a skin temperature-based fertility prediction (it leaves that to others). However, Garmin did partner with FDA on a study for atrial fibrillation detection via the optical sensor – so by 2026 we might see more medical features.

One notable addition in software: phone-free music and payments. Fenix 8 has Garmin Pay (NFC payments) and can store thousands of songs or sync playlists from Spotify/Amazon Music. And with the new speaker, you can play music aloud or with Bluetooth earbuds (plus you can hear audio prompts, etc.). Compatibility: Garmin watches work with both Android and iOS. They sync to Garmin Connect app, and you can get notifications from your phone (you can reply to texts if on Android, with canned responses). Garmin also has Connect IQ, an app store for watch faces and widgets (not as robust as Apple/Google, but you can add data fields, get Strava live segments, etc.). Price: The Fenix 8 is expensive – starting around $799 for base, and going up past $1100 for sapphire crystal and titanium models. To offer a lower entry, Garmin also released the Fenix E (or “Essential”), a scaled-back sibling to Fenix 8. The Fenix E has a slightly smaller 47mm AMOLED screen, uses some cheaper materials (polymer case, no sapphire, older HR sensor), and omits certain features (no dive mode, no flashlight, no mic/speaker, half the storage) wareable.com. It’s still durable and capable, but at ~$599 it targets those who want Garmin smarts without breaking the bank. Wareable concluded that while Fenix E is okay, “the Fenix 8 stands out as the superior choice, especially considering the significant compromises made by the Fenix E”.

Garmin also has other popular models in 2025: the Forerunner 965 (a lightweight runner’s watch with AMOLED, similar features to Fenix but less rugged, ~$600), the Venu 3 (focused on lifestyle and health, with ECG and nap tracking, ~$450), and specialized ones like Instinct 2X Solar (very rugged, infinite battery in sunlight) and Epix Pro (basically Fenix with AMOLED and no solar). But overall, the Garmin Fenix 8 is the flagship that demonstrates the trend of incredible battery life, outdoor mapping, and now even voice features in a smartwatch. If you’re an outdoor adventurer or serious about training, Garmin’s platform (Garmin Connect) is rich with analysis – though it can overwhelm casual users. 2025’s trends for Garmin include making their watches a bit more mainstream-friendly (hence adding AMOLED and voice). By 2026, perhaps Garmin will venture further into health monitoring (could we see blood pressure or glucose sensors in a Garmin? Unlikely that soon, but one can hope). More realistically, expect Garmin to refine its satellite communication features – after all, Apple and Qualcomm are enabling phones to send emergency SOS via satellite; Garmin already runs the inReach satellite messenger service. A Garmin watch that can send an emergency satellite message without a phone could be on the horizon. For now, Garmin holds the crown for battery and pro-grade durability, and the Fenix 8 shows you can add modern touches without sacrificing what hardcore users love.

Huawei: Watch 4 Series and GT 4 – Pushing Health Sensors Further

Huawei may be hampered by some trade restrictions (their watches don’t have Google services), but that hasn’t stopped them from innovating in wearables. The Huawei Watch 4 (and Watch 4 Pro) launched globally in mid-2023 and remains a top Huawei smartwatch through 2025, alongside the stylish Watch GT 4 (late 2023). Huawei’s watches run on HarmonyOS 3, which means they aren’t using Wear OS – instead, Huawei built its own platform and ecosystem. The upside: these watches often have better battery life than Wear OS devices and come loaded with unique health features. The downside: limited third-party apps and no native Google app support (no Google Maps, no Assistant, etc., though Huawei provides alternatives).

Design & display: Huawei Watch 4 has a premium build – the Pro version has a 48mm titanium case with sapphire glass, while the standard is 46mm steel. The AMOLED display is vibrant (1.5″, ~466×466 resolution) and can be always-on. Design-wise, Huawei went for a classic round face with a physical crown and a flush button. The newer Watch GT 4 comes in two sizes (46mm and a smaller 41mm aimed at women, with more fashion-forward designs like gold and rose gold options). The GT 4 has an AMOLED display too, just as bright, but a slightly simpler build (stainless steel/plastic combo) and even better battery thanks to its lower-power Lite OS.

Smart features: HarmonyOS on the Watch 4 allows for some apps via Huawei’s AppGallery, but as a review noted, “it’s no Google Maps…it pales in comparison to watchOS and Wear OS in terms of apps and payment support”. There is a Huawei Wallet for NFC payments, but limited acceptance outside China. You won’t get the breadth of apps – for example, there’s no Spotify (though you can load music files on the watch storage), and notifications work but are basic (i.e., you can’t reply from iPhone, etc.). On Android, you can respond to messages with some presets. Huawei did include eSIM support in Watch 4, so you can use it untethered for calls and LTE if your carrier and region allow. It has a built-in speaker and mic, so taking calls on the wrist is supported. They also have Celia, Huawei’s voice assistant, for offline commands (like “start a workout”) – “it works pretty well for opening apps and features using your voice,” according to Wareable. However, compared to Siri or Google Assistant, it’s limited in what it can answer beyond device control. Compatibility-wise, Huawei watches can work with both Android and iOS via the Huawei Health app, but some features are Android-only (e.g., importing contacts for direct watch calling). Wareable noted some quirks when paired with iPhones (duplicate notifications, etc.), likely due to Huawei Health app constraints on iOS.

Health and fitness: This is where Huawei tries to stand out. The Watch 4 is loaded with sensors: optical heart rate, SpO₂, skin temperature, and even a barometer for altitude. It also uniquely offers ECG – on Watch 4 Pro, there’s an ECG electrode on the crown, and Huawei got CE medical clearance for atrial fibrillation detection in Europe. They have a feature called TruSeen 5.0+ heart monitoring and TruSleep 3.0 for sleep analysis. One standout is the “Health Glance”all-in-one test: “a huge range of health metrics, bundled together – ECG (CE-cleared), arterial stiffness, heart rate, SpO₂, stress, and a new respiratory health score are measured in one session”. In about a minute, the Watch 4 runs these tests concurrently and then Huawei Health app shows a report. The arterial stiffness measurement is essentially a proxy for vascular health (by analyzing pulse wave velocity), something few other wearables do. The respiratory check is very novel – the watch actually asks you to breathe and cough into the microphone within 30 seconds to assess lung function. It’s an experimental metric (users found it a bit confusing on how to perform, and it just gives an “average/good” score), but it’s unique to Huawei. They are clearly positioning their watch as almost a medical screening tool (though these are wellness features, not diagnoses). Huawei also added continuous arrhythmia detection, blood pressure trend analysis (via arterial stiffness, not a true BP cuff), and even altitude health monitoring (the watch can warn you about low blood oxygen at high altitudes). For fitness, Huawei covers the bases with 100+ workout modes, built-in GPS (dual-band GNSS in the Watch 4 Pro), and advanced running metrics like Running Ability Index, training load, VO₂ max, recovery time, etc.. One fun feature: on some Huawei watches you can launch quick workouts or follow exercise animations (like breathing exercises or quick HIIT routines) – Huawei Health has a rich set of guided programs. Accuracy: Reviews found heart rate and GPS accuracy on Watch 4 to be solid – comparable to Apple Watch Ultra in GPS tracking, and heart rate tracking got a “clean bill of health” after some early issues on a previous Huawei model. Sleep tracking is also detailed, though Huawei’s sleep analysis tends to be a bit generous (it might rate your sleep as “great” when others say “just okay” wired.com). They have a feature called Health Trends which shows your 7-day and 30-day trends for key vitals (RHR, SpO₂, stress, sleep) in an easy chart. One omission: Huawei includes a temperature sensor on the Watch 4, but it currently doesn’t do much with it – “it’s a shame skin temperature isn’t tracked among the Health Trends… it’s not used to detect illness or for menstrual tracking, so it feels like a non-starter”. So Huawei lags Apple/Samsung in leveraging temperature data for women’s health or sickness detection.

Battery life: Huawei Watch 4’s battery life is middling – Huawei claims ~3 days on the steel Watch 4 and ~4.5 days on the larger Watch 4 Pro (typical use). Reviewers confirmed ~3 days is realistic if you don’t use always-on display. If you enable the always-on, it drops to 1.5–2 days. This is better than Apple/Samsung’s ~1 day, but far less than Huawei’s own GT series or a Garmin. The Watch GT 4, on the other hand, prioritizes battery: it can last about 7 days (46mm) to 4 days (41mm) with regular use, or up to 14 days in pure standby. The GT 4 achieves this by running Huawei’s LiteOS (no third-party apps, limited animations) but still covering all core tracking (HR, SpO₂, GPS). So basically, Huawei offers a range: Watch 4 for those who want more smarts, GT 4 for those who want style and battery.

Durability: Huawei Watch 4 Pro has sapphire and titanium, so it’s quite durable; 5ATM water resistance (50m swim-proof). The non-Pro has hardened glass and steel, 5ATM as well. GT 4 is 5ATM + IP68. There’s even a Huawei Watch Ultimate (launched early 2023) which is a $800 ultra-rugged watch with 100m dive rating and a fancy liquid-metal case – it’s Huawei’s equivalent of Apple Watch Ultra/Garmin MARQ, targeting outdoor adventurers (with things like freediving mode, dual-band GPS, etc.). The Ultimate was limited in global release but showed Huawei’s ability to innovate (it had the first non-Apple 100m dive rating in a smartwatch).

Software and pricing: Using a Huawei watch outside China means using Huawei Health app (available via AppGallery since Google Play version might be outdated due to sanctions). It’s a bit of a hurdle for some, but once set up, the app is good-looking and comprehensive. The Watch 4 retails around €450 (standard) to €700 (Pro) in Europe (though street prices fell). The GT 4 is more affordable: ~$270 for 46mm, $230 for 41mm.

Overall, Huawei’s watches in 2025 emphasize advanced health monitoring. They’ve packed in uncommon features like arterial stiffness and respiratory tests that you won’t find on Apple or Samsung yet. One expert review even called the Watch 4 “Huawei’s most complete health watch (bar the Watch D)”. (The Huawei Watch D is a special model with an inflatable cuff in the strap to measure blood pressure medically – a niche but notable device from 2022). In 2026, we expect Huawei to push further on health/medical features, possibly obtaining more certifications (for example, their heart arrhythmia detection was approved in China). They might also expand on the AI coaching trend – their new watches already give tips for running and daily breathing exercises. Also watch for whether Huawei can incorporate new tech like noninvasive glucose monitoring – they have research partnerships and could surprise us. The challenge for Huawei remains the software ecosystem: without Google, they will continue promoting their own services and making the case that their health features can outweigh the lack of some apps. For a user primarily concerned with health data and long battery, Huawei is indeed compelling. But in markets where Apple, Samsung, and Google are options, Huawei will mostly attract those who value its specific innovations (or perhaps those who use Huawei phones and are in that ecosystem).

Amazfit & Xiaomi: Affordable Wearables with High-End Features

Not everyone wants to spend hundreds on a smartwatch. Brands like Amazfit and Xiaomi have thrived by offering budget-friendly wearables that cover 80–90% of the functionality of big-name devices. In 2025, they continue to bridge the gap between basic trackers and premium watches, even introducing some cutting-edge features of their own.

Amazfit (by Zepp Health) has built a reputation for offering great value. Its GTR/GTS series of smartwatches routinely pack bright AMOLED screens, GPS, and long battery life at a fraction of the cost of an Apple Watch. The latest flagship is somewhat confusingly named the Amazfit Balance, which is essentially the Amazfit GTR 5 under a new name (launched in late 2023). The Balance is a round-faced smartwatch with a 46mm aluminum case and a gorgeous 1.5″ AMOLED display. It is incredibly lightweight and slim for its size, and it looks so polished that one reviewer said a coworker mistook it for a Samsung Galaxy Watch. Priced around $200, the Balance undercuts big brands while offering a lot of tech: it has dual-band GPS (very accurate, down to showing which side of the street you walked on), an array of sensors (accelerometer, gyroscope, ambient light, barometer), plus optical heart rate & SpO₂ sensors and even a new bio-impedance sensor for body composition. Yes, the Amazfit Balance can measure your body fat percentage, muscle mass, etc., similar to Samsung’s BIA feature, by passing a tiny current through your body – you just place fingers on the sides. Reviewers found the body comp feature “interesting” and results in the plausible range wired.com wired.com. The Balance also includes a microphone and a surprisingly loud speaker, enabling Bluetooth call support. What really stands out is battery life: Amazfit claims up to 14 days on a charge, and in testing, even with several tracked activities per day, it lasted about 10–12 days before needing a charge. That’s with the always-on display off; if you enable always-on, it’s shorter but still multiple days. This kind of longevity while having an AMOLED screen is where Amazfit outperforms most top brands – they optimize power well (adaptive refresh rate helps: 1Hz when idle, up to 60Hz when needed).

On the health and fitness front, Amazfit devices run the Zepp OS 2.0 platform. It’s lightweight and focused on core functionality. You get 24/7 heart rate, SpO₂ readings, stress monitoring, sleep tracking (with breathing quality and sleep stage info), and over 150 sport modes. Newer models like the Balance add AI-powered features under what Amazfit calls “Zepp Aura”. For example, the Balance offers “Morning Updates” – an AI summary of your sleep and schedule, and meditation and breath coaching. There’s also a “ChatGPT”-powered chatbot in the Zepp app you can ask health questions to (an experiment by Amazfit) wired.com. However, these AI features got mixed reviews – Wired found them unhelpful or buggy at times wired.com wired.com. The Zepp app provides a Readiness Score (like Fitbit’s – it looks at your recent activity, sleep, etc. and scores your preparedness for exertion). Amazfit also uses something called PAI (Personal Activity Intelligence) – a metric that aims to keep you above 100 points per week via any activity to maintain cardiovascular health. It’s less intuitive than readiness scores, and one reviewer called PAI “slightly ridiculous” due to its lack of context wired.com, but it’s there if you like chasing points. Accuracy-wise, Amazfit has improved a lot: the GPS is excellent, and heart rate is generally decent though can spike erroneously if the watch fits poorly (one tester saw some odd high readings until adjusting the strap wired.com). Sleep tracking is on par with Garmin and Fitbit in terms of identifying sleep periods.

Smart features on Amazfit are limited but improving. You get call notifications, message alerts (you can’t respond from the watch except with maybe some preset replies on Android), music playback control (no onboard music storage on most models except a couple like Stratos). Amazfit has a small app store for mini apps (like a calculator, some games, and Alexa). Yes, many Amazfit watches include Amazon Alexa support when connected to your phone – you can ask the watch for weather or to set reminders. No third-party apps like Google Maps natively, though some clever users sideloaded apps or watch faces that do more.

Amazfit’s other popular models in 2025 include the GTS 4 Mini (compact square watch ~$100), the T-Rex Ultra (a rugged outdoor watch), and the Band 7/8 (super affordable fitness bands ~$50). They even launched the Cheetah series in 2023 aimed at runners, with AI training plans. Overall, Amazfit’s niche is delivering 80% of flagship features at 30–50% of the price. For example, the Balance has a bright AMOLED, GNSS, 24/7 health tracking, and 14-day battery – something like that from Apple doesn’t exist, and from Garmin would cost triple (Garmin’s AMOLED watches with 2-week battery are >$800). The trade-offs are a less robust app ecosystem and some occasional software quirks. As Wired put it, “Amazfit’s new Balance has a clear, crisp screen, mostly accurate tracking, decent battery life… but too much upselling of subscriptions and some AI features that don’t yet live up to the hype” wired.com wired.com. Still, for budget-conscious consumers, Amazfit is a top option. Expect Amazfit to continue pushing into health – perhaps we’ll see ECG or blood pressure sensors in future models as those patents trickle down.

Xiaomi, on the other hand, is known for its extremely popular Mi Band (Smart Band) series and some entry-level smartwatches. The Xiaomi Smart Band 9 is the latest as of 2025 (with a Band 10 likely due late 2025). The Smart Band 9 is an affordable fitness band (around $50) that offers a surprisingly rich feature set. It has a 1.62-inch AMOLED touch display – that’s almost as big as a smartwatch screen, but in a slim pill-shaped module that fits into a silicone band. Xiaomi innovated the band design with Band 8 by allowing the tracker capsule to be popped out and worn in different ways (necklace, clipped to shoe as a running pod, etc.), and Band 9 continues that: “a versatile design that can detach from the strap and be worn as a necklace or running pod (Pebble Mode)”. The Band 9’s display is much brighter, up to 1200 nits (double the Band 8’s 600 nits) – noticeable in all conditions. It’s a vivid screen for a band, making stats easy to see at a glance.

Despite its low price, the Smart Band 9 covers all essential tracking: continuous HR, SpO₂, stress, sleep, menstrual tracking, and even offers 100+ sport modes (mostly to log exercise duration/calories, as it doesn’t have built-in GPS unless you get the special Band 9 Pro variant). Xiaomi improved the sensor module for Band 9 – the PPG heart sensor is redesigned and claimed to be “16% better” at heart rate and blood oxygen tracking than Band 8, and sleep tracking accuracy improved ~8%. In testing, Band 9’s heart rate was indeed more reliable during easy activities, though still struggled during very intense exercise (common for optical sensors). One downside: no ECG, no advanced metrics like EDA or skin temperature on the Mi Band (those are above its pay grade). It’s purely focused on fitness and wellness basics. But for many, that’s enough. The Band 9 will count steps, distance (via connected GPS from your phone), active minutes, and give you a sleep score. It even has some fun extras like breathing exercises and PAI score (Xiaomi, like Amazfit, uses PAI metric too). Battery life is fantastic – around 14–18 days on Band 9 with normal use (less if you enable features like always-on time display). You can easily get 1–2 weeks per charge, which is a huge convenience advantage over daily-charge smartwatches.

Xiaomi also released a Smart Band 9 Pro in 2024 with a larger 1.7″ rectangle screen and built-in GPS – basically a lightweight smartwatch – at around $70. And they have some proper smartwatches like the Xiaomi Watch 2 Pro (Wear OS-based, launched late 2023) in global markets and the Redmi Watch series. Those haven’t made as big a global splash as the Mi Bands, partly due to stiff competition in the smartwatch segment. But notably, Xiaomi’s Wear OS Watch 2 Pro shows Xiaomi dabbling in the high end, running Qualcomm’s W5+ chip and Wear OS 3.

For most users, Xiaomi’s Mi Band remains the go-to budget fitness tracker. If you want core fitness tracking, phone notifications, and even some smartwatch-like conveniences (like music control, weather, and a bit of app integration) for under $50, it’s hard to beat. The Band 9 is one of the “best cheap fitness trackers”, as LiveScience put it, offering a comfortable wear, pleasant display, and reliable basics. And as Wareable noted, until the Band 10 arrives, the Band 9 is Xiaomi’s recommended tracker for logging the basics. Expect Xiaomi to continue incremental upgrades – the Band 10 might add more sports analytics or perhaps a very rudimentary voice assistant (just speculation), but mainly they up the display and sensor quality each generation. Xiaomi’s strategy is volume at low margins, so they pack as much as possible while keeping price low.

Durability: Amazfit and Xiaomi devices are generally 5ATM water-resistant as well, so you can swim with them. They may not have fancy sapphire glass or MIL-spec ratings, but they hold up for everyday use.

In summary, Amazfit and Xiaomi exemplify the 2025 trend of democratizing wearable tech. You don’t need to spend $300+ to get an AMOLED display, advanced health sensors, or GPS tracking. These brands are offering multi-day battery life which often outclasses the giants, and they are even experimenting with AI and new metrics in their own way. For consumers, this means more choice: if you primarily care about core fitness tracking and notifications (and saving money), a $50–$200 device from Amazfit or Xiaomi can serve you very well. The gap between budget and premium is narrower than ever in functionality – often it’s in polish, support, and ecosystem where the premium brands justify their cost.

Innovations and What to Expect in 2026

The wearable tech race is accelerating, and 2025 has set the stage for even more exciting developments in 2026. AI will continue to be the big story – we’re likely to see more watches offering on-device AI coaching, like personalized workout and nutrition suggestions based on your data. As Starmax (an OEM) noted, we’ve “gone past the era of passive health tracking” – AI-driven smartwatches learn your patterns and can even “predict health issues before they become life-threatening” istarmax.com istarmax.com. In practical terms, this could mean wearables alerting you days in advance if your metrics indicate you might be getting sick or overtrained. Fitbit’s labs are already testing predictive algorithms (e.g. using daytime alertness questions to tailor your ideal sleep schedule). By 2026, these experimental features may roll out widely, making wearables more proactive health guardians.

On the health sensor front, the trend is towards clinical-grade capabilities. More wearables will likely obtain regulatory approvals: e.g., Google’s Pixel Watch getting FDA clearance for its pulse detection or irregular rhythm notifications in the US (to match Apple and Fitbit). Samsung might push its blood pressure feature toward broader approval (currently it’s not available in the US). There’s also ongoing R&D in noninvasive glucose monitoring for diabetics – rumor has it Apple and others have prototypes, but it’s incredibly challenging. We probably won’t see that in a product in 2026, but if any company cracks it, it will be a game-changer to measure blood sugar from a watch without a needle. We could see better blood pressure solutions though; Huawei and others have shown cuff-less tech that estimates BP through arterial stiffness or optical sensors, and Samsung has the Pulse Wave Analysis (though requiring calibration). Perhaps by late 2026, a major brand might release a watch that can measure blood pressure on the wrist without regular cuffs – that would be a huge innovation if accurate.

Displays and hardware will also evolve. Micro-LED displays, which promise OLED-level contrast without burn-in and with higher efficiency, are the next big thing for wearables. As mentioned, Apple has been “eyeing microLED” for Apple Watch, but shelved its 2024 plans due to cost. We might see a micro-LED Apple Watch by 2026 or 2027, likely debuting on an Ultra model first given the expense. When it arrives, expect brighter screens that sip battery, potentially extending Apple Watch battery life beyond the 1–2 day mark. In the Android realm, Samsung and others might also explore micro-LED or refine their OLED tech for efficiency. We’ve already seen Pixel Watch 3 adopt LTPO and drop refresh to 1Hz to save power – such techniques will become standard, so always-on displays won’t be such battery hogs.

Another hardware trend: wearable form factors diversifying. 2025 saw smart rings become real (Oura’s success and now Samsung’s Galaxy Ring). By 2026, rings might go mainstream as a complement or alternative to watches – possibly Google/Fitbit or Apple might consider a ring device given Samsung’s jump. We also see growth in AR glasses (Apple Vision Pro isn’t fitness-focused, but Meta, Xiaomi, etc., are working on lighter smart glasses that could one day integrate fitness HUDs or coaching – beyond 2026 perhaps). Earbuds as health trackers is another angle: 2025 earbuds from Sony and Jabra have heart-rate sensors; Samsung and Apple may do the same in coming generations, giving you yet another way to measure health (imagine your AirPods checking your heart rate and body temp). These would complement watches, creating an ecosystem of body sensors.

In terms of software and ecosystem, expect closer integration between wearables and healthcare providers. FDA-cleared features and partnerships with medical research will expand. Apple’s research kits and Fitbit/Google’s health studies are collecting vast data – which could translate into wearables that detect signs of sleep apnea, atrial fibrillation (already happening), or even mental health conditions through patterns in typing, voice, and vitals (Apple is researching depression detection via device use metrics). Mental health is a new focus: Apple introduced mood tracking in 2023, Fitbit offers stress management scores – by 2026 wearables might proactively suggest mindfulness breaks when stress is detected (some already do, like Garmin and Apple prompting breathing exercises if your stress is high).

Battery technology improvements (beyond just efficiency) could appear. Solid-state batteries or new chemistries might not hit wearables by 2026, but companies are refining charging. In 2025 we saw faster charging – e.g., Huawei Band 8 can give 2 days of use in a 5-minute charge. That trend will continue: quick 10-minute top-ups for a day of smartwatch use will be a standard feature, addressing battery anxiety even if capacity doesn’t double.

Finally, expect more competition and options. Tech giants like Meta (Facebook) haven’t entered smartwatches yet – will 2026 see a new entrant? (Meta seems more focused on AR/VR and perhaps rings like the CTRL-Labs neural input band). Traditional watchmakers like Casio, Citizen, etc., are also adding smart features (Casio’s G-Shock with heart rate, etc.). The consumer wins as more players means more innovation.

In conclusion, the 2025 crop of smartwatches and fitness trackers deliver an impressive mix of style, connectivity, and health superpowers. Whether you’re an athlete looking for robust training metrics, someone aiming to improve wellness with a bit of coaching, or just want to not miss texts while away from your phone, there’s a wearable for you. Notable trends of 2025 – like AI health insights, advanced sensors (ECG, SpO₂, skin temp) even in budget devices, and new form factors like rings – set the stage for 2026, where we anticipate even smarter, more sensor-packed, and diverse wearables. As one industry blog noted, “the future of wearables is ticking fast”, and staying in the know on these trends can help you decide when to upgrade your device istarmax.com. One thing is certain: our wearables are becoming ever more capable companions, and they’re poised to play an increasingly important role in our daily health and tech life.
