The 41mm version usually has a smaller capacity, probably between 300-400mAh.<\/p>\n\n\n\n<p>Expected S4 41mm: If power consumption is optimized, it may maintain a similar capacity (such as 320-380mAh), but extend the battery life through chip upgrades (such as a new generation processor).<a href=\"https:\/\/www.batteriesfast.co.uk\/smart-watch-battery\/Xiaomi\" target=\"_blank\" rel=\"noreferrer noopener\"><strong><u>Xiaomi Watch S4 41mm Battery<\/u><\/strong><\/a>performance: Typical use (heart rate, notifications, exercise monitoring): about 7-10 days. Heavy use (GPS, always-on screen): about 3-5 days. Basic mode: may be more than 2 weeks. Charging technology: most likely to support magnetic fast charging, charging time is about 1 hour (0-100%).<\/p>\n\n\n\n<p>May be compatible with wireless charging (such as Qi protocol).<\/p>\n\n\n\n<p>Energy saving improvements: lower power consumption screen (such as LTPO OLED). System-level power saving optimization (such as adaptive refresh rate, background task management).<\/p>\n\n\n\n<p>Xiaomi Watch S4 41mm<\/p>\n\n\n\n<p>The Watch S4 41mm is equipped with a 1.32-inch circular AMOLED display with a resolution of 466 x 466 pixels, a refresh rate of 60Hz, and a peak brightness of 2,200 nits. Like its Watch S4 sibling, it has a 5ATM water resistance rating and weighs 32 grams. Xiaomi brings an upgraded 4-LED + 4PD heart rate module for accurate health tracking, and an improved version of the Xiaomi Xring T1 chip, whose modem is 35% more efficient than the modem in the regular Xiaomi S4 watch. It also supports real-time swimming heart rate tracking and has a&nbsp;<a href=\"https:\/\/www.batteriesfast.co.uk\/smart-watch-battery\/Xiaomi\" target=\"_blank\" rel=\"noreferrer noopener\"><strong><u>Xiaomi Watch S4 41mm Battery<\/u><\/strong><\/a>&nbsp;life of up to 8 days. SmartBand 10<\/p>\n\n\n\n<p>The SmartBand 10 upgrades to a 1.72-inch AMOLED display with a 60Hz refresh rate and a peak local brightness of up to 1500 nits. While the design remains unchanged from last year&#8217;s SmartBand 9, the new model has a narrower bezel and a ceramic bezel version, which is also the first time it is available outside of China.<\/p>\n\n\n\n<p>Xiaomi claims that the Band 10 can provide more accurate health and activity tracking thanks to its 9-axis sensor and sleep monitoring with a guided improvement plan.<\/p>\n\n\n\n<p>The Band 10 also features an upgraded vibration motor and the same 233mAh as its predecessor<\/p>\n\n\n\n<p>Expected features of the Xiaomi Mi Band 10 battery (if released in the future):<\/p>\n\n\n\n<p>Battery capacity: If the Band 10 is launched, the capacity may remain between 200-300mAh, and the battery life may be optimized.<strong><u><a href=\"https:\/\/www.batteriesfast.co.uk\/smart-watch-battery\/Xiaomi\" target=\"_blank\" rel=\"noreferrer noopener\">Xiaomi Smart Band 10\u00a0\u00a0Battery<\/a><\/u><\/strong> life: Typical use scenarios (such as heart rate monitoring, notification reminders): about 7-14 days.
