- Release: Samsung’s next-gen Galaxy S26 Ultra is tipped for a January 2026 launch [1], while Xiaomi’s 17 Pro Max debuted in China in Sept 2025 (with a likely global rollout in early 2026) [2] [3].
- Chipset: The S26 Ultra will use Qualcomm’s Snapdragon 8 Elite Gen 2 (with Exynos variants in some regions) [4]. Xiaomi’s 17 Pro Max runs on the newer Snapdragon 8 Elite Gen 5 (16 GB RAM/1 TB storage in top trim) [5].
- Battery & Charging: Samsung sticks to a ~5,000 mAh battery but finally jumps to 60 W wired charging [6] [7]. Xiaomi takes a different approach: the 17 Pro Max packs a 7,500 mAh battery (L-shaped design) with 100 W wired charging [8] [9]. Both phones support fast charging and advanced battery tech.
- Displays: Both phones use ~6.9″ OLED panels. The S26 Ultra’s display (expected to be ~6.89″) likely features Samsung’s latest M14 material, anti-reflective glass and even an AI-powered privacy filter [10] [11]. The Xiaomi 17 Pro Max has a 6.9″ main screen (with new M10 tech) and a unique 2.7″ secondary “Dynamic Back Display” on the rear [12] [13] – a small cover-screen wraparound used for notifications, widgets and selfies.
- Cameras: Samsung’s S26 Ultra is rumored to keep the 200 MP main sensor but upgrade optics – for example a wider f/1.4 aperture on the main camera and a brighter 5× periscope (50 MP) with f/2.9 (up from f/3.4 on the S25) [14]. Xiaomi 17 Pro Max uses a Leica-backed triple 50 MP array (main f/1.67, ultrawide f/2.4) and a periscope telephoto: 5× optical zoom (f/2.6) and even a 30 cm macro mode [15].
- Other Features: The S26 Ultra will continue to include an S Pen stylus (albeit re-styled) [16], supporting Samsung’s productivity niche. Xiaomi’s 17 Pro Max has no stylus but offers heavy AI integration (HyperOS 3 with XiaoAI assistant) and extras like Wi-Fi 7 [17]. Samsung’s One UI 8.5 will introduce new on-device AI tools (meeting translation, smart clipboard, “Social Composer” etc.) [18].
- Price & Market: Samsung’s ultra-premium pricing is expected (~$1300+ for Ultra) [19], whereas Xiaomi launched the 17 Pro Max at ~¥5999 (~$840) in China [20]. Xiaomi’s strategy openly targets Apple’s iPhone 17, even skipping a generation to match numbering [21] [22]. Samsung, meanwhile, focuses on out-AI’ing rivals.
With those facts in mind, let’s dive deeper into what each flagship offers and how they stack up.
Samsung Galaxy S26 Ultra: Rumors and Expectations
Samsung is shaking up the S-series for 2026. Industry leaks suggest Samsung will unveil the Galaxy S26 Ultra (alongside a new “S26 Edge” and base S26/S26 Pro) at an Unpacked event in early 2026 [23] [24]. Reports even hint at premium pricing (~₹159,990 in India, ~$1,900) [25]. As PhoneArena notes, the S26 Ultra name will stick, but Samsung may drop the old “Plus” name in favor of a slimmed-down “Edge” model [26] [27].
Rumors emphasize no major size increase: the Ultra’s screen is pegged around 6.89″ (virtually the same 6.9″ as S25) [28] [29]. Instead, Samsung seems focused on incremental refinements. Tipsters (like leaker IceUniverse) expect 60 W wired charging – a 33% jump from the S25 Ultra’s 45 W [30] [31]. That would finally outpace Apple’s ~40 W iPhone charge rate [32] [33]. Battery capacity, however, appears unchanged: certification hints at a ~4,855 mAh cell (advertised as ~5,100 mAh), essentially the same ~5,000 mAh pack Samsung has used since 2020 [34] [35]. (As PhoneArena’s Ilia Temelkov dryly notes, Samsung “may feature the same 5,000 mAh battery as every top-tier flagship since 2020” [36].) The hope is that faster charging and efficiency gains compensate for a non-growing battery.
Under the hood, S26 Ultra is expected to get Qualcomm’s next-gen Snapdragon 8 Elite Gen2 chip (with an Exynos variant in some regions) and possibly up to 16 GB of RAM [37]. On camera, Samsung’s focus seems to be zoom optics: leaks indicate the 50 MP 5× periscope lens will use a much wider f/2.9 aperture (vs f/3.4 on the S25) [38], boosting low-light zoom shots. The 200 MP main sensor is believed to carry over but with tweaks (a rumored f/1.4 aperture versus f/1.7 before [39]) to grab ~47% more light. Samsung may also add a laser autofocus and next-gen processing. In short, analysts say Samsung is “catching up” on zoom and image quality to rivals like Xiaomi and Google [40] [41].
Samsung is also pushing AI and software. Leaked One UI 8.5 code suggests features like a “Meeting Assist” real-time translator, “Touch Assist” for smarter text selection, a smart clipboard (on-demand translate/summarize), and a “Social Composer” to auto-generate captions/reviews from images [42]. Samsung is even exploring multiple AI “agents” – its own Gauss model, Google Gemini, Perplexity AI, etc. – to power these tools [43] [44]. As one industry summary observes, Samsung’s “strong push toward generative AI” will likely grab attention [45]. PhoneArena’s Iskra Petrova notes Samsung may even “team up with Perplexity AI for the Galaxy S26” [46], underscoring how seriously Samsung is taking on-device intelligence. All of this suggests the S26 Ultra aims to add “AI magic” to everyday tasks – from translation to photo editing – in a way Samsung hasn’t before.
Design-wise, leaks hint at a more curved, sleeker look. Leaked renders show rounded corners (more iPhone-like curves [47]) and even smaller bezels, though the overall 6.89″ screen size remains. The Ultra is said to use anti-reflective glass and perhaps Samsung’s M14 OLED material (a brighter, more efficient panel) [48] [49]. One rumored surprise: a software-driven privacy filter (codenamed “Flex Magic Pixel”) that makes side-angle viewing harder, protecting onlookers from peeking at your screen [50] [51]. Crucially, Samsung will keep the S Pen: early chatter had feared a stylus drop for thinness, but Samsung apparently redesigned the S Pen to fit the curved new frame [52] [53]. The S Pen slot (sans Bluetooth buttons) remains, letting Galaxy fans continue using the signature stylus.
In summary, the S26 Ultra appears evolutionary: largely the same 6.9″ display and ~5,000 mAh battery as before, but with much faster charging (60 W), beefed-up optics, and a major AI/software overhaul [54] [55]. As PhoneArena wryly observes, Samsung “may be repeating its predecessors’ biggest mistake” by not upsizing the battery [56]. But if the trade-off nets ultra-quick charging and genuinely smarter AI features, Samsung will bank on that being worth it. All eyes will be on Galaxy Unpacked 2026 to see which rumors stick.
Xiaomi 17 Pro Max: China’s Bold iPhone 17 Rival
Xiaomi has already rolled out the Xiaomi 17 series (skipping “16” to match Apple’s numbering) with an eye on Apple’s iPhone 17. The lineup includes the base 17, the 17 Pro, and the top-of-the-line 17 Pro Max, unveiled in Beijing in Sept 2025. Xiaomi CEO Lei Jun openly compared the new phones to Apple’s, repeatedly highlighting how the 17 series “wins on battery, performance, photography, and more” [57] [58]. As The Verge notes, the launch felt like “Xiaomi had Cupertino in mind” [59]. The idea: “take the fight” to Apple by matching its flagship’s naming and exceeding it on specs.
The Xiaomi 17 Pro Max is a specs beast. It sports a Snapdragon 8 Elite Gen 5 chip (the current Android flagship processor) with 16 GB RAM and up to 1 TB storage [60]. Its main display is a sharp 6.9″ OLED (allegedly with new “M10” tech for high brightness/efficiency) [61]. But what truly stands out is the secondary rear display – Xiaomi’s “Dynamic Back Display.” This is a 2.5″ by 1.8″ touch panel (about 904×572 resolution, 120 Hz, up to 3500 nits) built into the camera plateau on the back [62] [63]. It shows a clock or notifications, serves as a selfie viewfinder using the main cameras, and even runs simple apps or games with a special “Game Boy” style case [64] [65]. Wired’s Simon Hill calls this double-screen setup “surprisingly polished” – it’s unconventional, but it offers practical perks like not having to flip the phone for notifications [66]. In short, the 17 Pro Max uses the rear display for quick info, AI-pinned reminders, music controls, and top-notch selfies with its 50 MP cameras [67] [68].
That brings us to battery life – another Xiaomi trump card. The Pro Max packs a massive 7,500 mAh battery (with a new L-shaped cell design), and charges at 100 W (wired) or 50 W (wireless) over PPS [69] [70]. Xiaomi claims this easily delivers two days of use; in its launch demo, even an iPhone 17 with a 5,000 mAh external battery couldn’t outlast the Xiaomi in a video loop test [71]. In practice, Wired found the Pro Max easily lasts about two days of mixed use [72]. The smaller Xiaomi 17 Pro (6.3″) still has a respectable 6,300 mAh battery. (Interestingly, the base Xiaomi 17 unexpectedly has a 7,000 mAh cell – it’s slightly smaller than the Pro but even bigger battery!). These are by far the largest batteries in any 6–7″ flagship, part of Xiaomi’s “crush iPhone” strategy [73] [74].
Camera-wise, Xiaomi partners with Leica for its optics. Both the 17 Pro and Pro Max use a triple 50 MP rear array. They share a 50 MP main (f/1.67) and 50 MP ultrawide (f/2.4). The telephoto differs: the Pro Max uses a larger 1/2.52″ sensor with a 5× Prism Periscope lens (f/2.6) and can even focus down to 30 cm for macros [75]. (The smaller 17 Pro has a 3× telephoto on its 50 MP sensor.) Despite the rectangular camera bump and aggressive design, Xiaomi’s approach is to match iPhone photography with abundant hardware. There’s no foldable glass like Mi 13 Ultra; instead Xiaomi claims the Pro Max’s glass is extremely tough – it once even let a skater glide across it in a promo video. The result: top-tier images and more detailed zoom than before. (Insiders say Xiaomi’s main camera sensor is 1/1.4″, larger than many competitors’ 1/1.68″, which helps low-light.) In all, reviewers call the 17 Pro Max a “specs beast” [76] built for heavy-duty photography, gaming and multitasking.
Beyond hardware, Xiaomi packs the 17 series with modern tech: Wi‑Fi 7, UWB, seamless cross-device features (it even touts a Mac/ iPad ecosystem link), and a new HyperOS 3 on Android 16 with AI smarts. Xiaomi’s Xiao AI assistant can proactively suggest apps and reminders, and can push info to that rear display (e.g. flights, QR codes). As Wired notes, this AI extends even to playful elements (like animated pets on the back screen) and to connectivity (a Game Boy–style case turns the phone into a handheld console) [77] [78].
Currently, the Xiaomi 17 Pro Max is China-exclusive. It launched on Sept 27, 2025 with pricing from ¥5,999 (≈$840) [79]. Xiaomi plans to bring at least some 17 models overseas by early 2026 (likely around Mobile World Congress in March) [80]. However, as PhoneArena cautions, Apple’s global ecosystem advantage remains a hurdle – Xiaomi’s hardware impresses, but availability is limited outside China [81].

Summary of Strengths
- Samsung S26 Ultra: Leverages Samsung’s ecosystem (S Pen, Galaxy Buds/Watch integration, etc.) and adds advanced AI tools. Rumored advantages are much faster charging and top-tier display quality. It may lag Xiaomi in raw battery size, but hopes to compensate with efficiency.
- Xiaomi 17 Pro Max: Outguns on paper with colossal battery and a novel dual-screen design. Its goal is endurance and media/power-user chops. Xiaomi also undercuts typical flagship pricing and flaunts its specs (even staging iPhone comparisons [107]). The trade-off is somewhat narrower availability outside China and a bold (if polarizing) design.
AI and Software: Android Titans Face Off
Both phones spotlight AI. Samsung’s marketing has been touting “Galaxy AI” for a year, and leaks suggest One UI 8.5 will infuse AI deeply into the UI. New features like live translations in calls, smarter text editing, and auto-generated social posts hint at a more assistant-like phone. Samsung may even let the user pick among AI “agents” (its Gauss model vs Google’s Gemini vs Perplexity) [108] [109] – a unique approach. In practice, that could mean your phone not only translates a video call in real time but also summarizes articles or drafts replies via AI. Analysts note this is Samsung “doubling down” on AI so it isn’t outmatched by Google or Apple’s on-device AI efforts [110].
Xiaomi, for its part, bills the 17 series as highly AI-driven too. Its HyperOS 3 skin uses XiaoAI to learn from your habits – for example, pre-loading relevant apps or showing live info on the back screen. Xiaomi also leverages AI in the camera (e.g. image tuning via Leica’s Master AI), and even built a playful AI into the back display (the animated pets and themes react to battery level, environment, etc.) [111] [112]. While Samsung’s AI push focuses on productivity and privacy (with features like the rumored “Flex Magic” privacy display filter [113]), Xiaomi’s is more of a lifestyle angle (games on the back screen, gadget-themed cases, and live notifications). Both promise richer experiences: Samsung via productivity/translation, Xiaomi via unprecedented battery life and gadget-like novelty.
Market Outlook and Availability
As of late 2025, the Xiaomi 17 Pro Max is a China-only flagship. Xiaomi’s PR already openly called it a rival to the iPhone 17 (and even fed Apple-centric demos) [114]. In China, Xiaomi has strong carrier and retail reach, so the 17 series will sell well there. The global picture is less certain: Xiaomi typically brings one or two models to Europe, often a few months later. Reports suggest some Xiaomi 17 models will hit Europe by Spring 2026 (possibly around MWC) [115] [116]. The US market remains off-limits for Xiaomi.
Samsung’s Galaxy S phones are sold worldwide, though S26 Ultra’s Exynos variant (for EU) may see limited supply if rumors of low yields are true [117]. Samsung’s strong global marketing and carrier support mean the S26 Ultra will likely be a major global launch, with trade-in and carrier deals. Price will be high (PhoneArena expects Ultra to start around $1300+ [118], and leaks suggest even higher in India [119]).
An expert in PhoneArena observes that Xiaomi’s aggressive strategy does put it “on the same stage” as Apple – by matching naming, design cues, and proving specs superiority [120]. But Samsung’s strategy is different: it isn’t as much about undercutting Apple on price, but about pushing new tech (like AI and display innovation) while commanding flagship prices. In both cases, the competition also hinges on ecosystems. Apple’s walled garden is a tough act to break, but Samsung relies on Android/OneUI with Galaxy hardware, while Xiaomi leans on versatility and battery bragging rights.
Conclusion: Two Titans, Different Paths
In summary, the Samsung Galaxy S26 Ultra and Xiaomi 17 Pro Max represent two very different visions of a 2026 flagship. Samsung’s offering (still unannounced) appears to be an evolution of its Ultra line – same large screen and ~5,000 mAh battery, but with faster charging (60 W), improved zoom cameras, sleeker design, and a big bet on AI features [121] [122]. Xiaomi’s 17 Pro Max is a revolutionary play – huge 7,500 mAh battery, dual displays (front and back), triple 50 MP Leica cameras, and top Snapdragon power – all at a bargain price point [123] [124].
Which is “better” depends on what you value. If you want raw endurance, a stand-out rear screen, and one of the fastest-charging phones ever, Xiaomi wins on paper. If you prefer Samsung’s ecosystem (stylus, deep integration) and want cutting-edge AI tools plus guaranteed global support, S26 Ultra has the edge – assuming Samsung’s rumors pan out. As The Verge summed up Xiaomi’s approach: it’s playing to win by adding “extra ammo” (battery, performance, fun extras) against the iPhone and other rivals [125]. Samsung, meanwhile, is playing to win by fine-tuning its flagship formula and betting on AI to captivate users.
Ultimately, consumers in 2026 will choose based on priorities: perhaps raw specs and longevity (Xiaomi) vs brand trust and ecosystem (Samsung). We won’t know until Samsung officially unveils the S26 series (likely Jan ’26) and Xiaomi expands distribution. For now, the battle lines are drawn between these tech powerhouses. As PhoneArena’s iPhone-17-vs-Xiaomi piece noted, “on paper” the Xiaomi 17 series is stacked for victory [126] – but Samsung’s S26 Ultra is ready with its own tricks. The flagship war for 2026 is just heating up, and it promises to keep us watching all year.
