# Xiaomi Watch S5 41mm Leaks Reveal Significant Battery Capacity Upgrade The upcoming 41mm smartwatch model features a 590mAh battery and increased peak display brightness. - **Source:** [GSMArena.com - Latest articles](https://brifing.si/source/ae58cd90-1e26-4445-9a9c-963b7954a50c) - **Published:** 2026-11-03 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/9b650820-3629-4b45-b28a-a000f73124d4 ## Hardware Evolution and Dimensions The upcoming Xiaomi Watch S5 41mm features a stainless steel chassis measuring 9.9mm in thickness. This represents a slight increase from the 9.5mm thickness found in the previous S4 41mm model. This design adjustment accommodates a larger internal architecture, specifically enabling the integration of a significantly more powerful battery unit for users. ## Battery Capacity and Runtime The device houses a 590mAh battery, nearly doubling the 320mAh capacity of its predecessor, the S4 41mm. This hardware upgrade supports up to 8 days of normal usage or 14 days in power-saving mode. By utilizing a proprietary version of HyperOS instead of Wear OS, the watch achieves these extended runtime performance metrics. ## Display and Visual Performance The 1.32-inch OLED screen retains the previous resolution of 466 x 466 pixels. However, the peak brightness has been increased to 3,000 nits, significantly improving outdoor visibility compared to earlier iterations. The device maintains a 5 ATM water resistance rating, ensuring durability for users in various aquatic environments and daily physical activities. ## Integrated Sensor Suite The watch includes an optical heart rate sensor and three dedicated temperature sensors for menstrual cycle tracking. Additional hardware components consist of a barometer and a compass for navigation. Outdoor positioning is managed by a dual-band receiver supporting GPS, Galileo, GLONASS, BeiDou, and QZSS, ensuring precise tracking capabilities for diverse outdoor athletic activities. ## Connectivity and Wireless Standards Connectivity is facilitated through Bluetooth 5.4, providing stable communication with paired smartphones. The device also incorporates NFC technology for contactless payments and Wi-Fi 6 (ax) support for faster data transfers. These integrated wireless standards ensure the watch remains compatible with modern networking environments while maintaining efficient power consumption during active data synchronization tasks. ## Comparative Product Positioning The 46mm version of the Watch S5 is thicker at 11mm, housing an 815mAh battery and a 1.48-inch display. Meanwhile, the standard Xiaomi Watch 5 offers a 930mAh battery and a 1.54-inch screen but runs Wear OS. Unlike the S5 series, the standard Watch 5 model does not currently offer a 41mm variant option. ## Pricing and Market Availability Leaked data from Czechia suggests a price point of CZK 5,469 for the 41mm model, which is higher than the CZK 3,999 launch price of the 46mm version. Other reports indicate a potential price of €240. Currently, the 46mm model is listed at CZK 3,699, which converts to approximately €152 on official channels. ## Strategic Implications of Design Xiaomi's decision to prioritize battery capacity over slimness in the 41mm segment reflects a focus on long-term endurance. By opting for proprietary HyperOS, the company sacrifices third-party Wear OS features to maximize efficiency. This strategy targets users who value extended battery life and specialized health tracking over broad application ecosystem compatibility. ## Sources covering this story - https://www.gsmarena.com/xiaomi_watch_s5_41mm_leaks_expect_a_big_increase_in_battery_capacity-news-75323.php — --- _Summary written by Brifing from the original reporting.
