Xiaomi Watch S4

Xiaomi's large 2025 lifestyle and fitness smartwatch, combining a bright 1.43-inch AMOLED display, interchangeable bezel system, dual-frequency GNSS, extensive health and workout tracking, Bluetooth calling, NFC payments and long battery endurance. The Watch S4 is particularly strong for buyers who want accurate outdoor positioning, broad fitness functionality and premium-looking hardware without paying Wear OS or flagship sports-watch prices.

  • The Watch S4 provides an unusually strong feature set for a mid-range smartwatch.
  • Its 1.43-inch AMOLED display provides a large viewing area for workouts, notifications and health information.
  • The 466 x 466 resolution produces sharp text and detailed watch faces.
  • Xiaomi specifies an HBM brightness of approximately 1,500 nits.

If it was our money

The Xiaomi Watch S4 is a strong value choice for buyers who want long battery endurance, a bright AMOLED display and genuinely useful fitness features without paying flagship smartwatch prices. Its L1+L5 dual-frequency GNSS is particularly impressive for the class, while more than 150 sport modes, running-form analysis, structured running courses, advanced sleep tracking, Bluetooth calling and NFC make it significantly more capable than a basic fitness tracker. The main compromises are its very large 47.3mm case, limited third-party app ecosystem, lack of ECG and the absence of premium features such as sapphire glass or full offline mapping. Buyers with smaller wrists should consider the separate Watch S4 41mm. Android users who want Google Play and deeper app functionality should instead consider Wear OS, while serious runners should compare Garmin. When priced well below those alternatives, however, the Watch S4 offers an excellent amount of hardware and fitness capability for the money.
