Inside the Battery Revolution: How Your Smartphone Will Charge Faster, Last Longer, and Save the Planet
Most smartphone batteries retain about 80% of their capacity after 500 complete charge cycles (roughly 1.5–2 years). Xiaomi demonstrated 210W HyperCharge that can fill a 4,000 mAh battery in about 8 minutes. Qi2 was announced in 2023 and supports up to 15W wireless charging, with the iPhone 15 (late 2024) first to officially support it. In 2024 Apple switched the iPhone to USB-C, enabling universal high-powered charging and compatibility with GaN chargers. Apple’s Optimized Battery Charging pauses charging near 80% until needed, while Google’s Pixel Adaptive Charging schedules the final 20% to finish by your alarm time. Honor Magic5 Pro
