Xiaomi Watch S4 Silver – a powerful smartwatch for fitness and well-being
Xiaomi Watch S4 Silver is an advanced smartwatch that combines fresh silver-toned design, a lightweight build and versatile wellness features. The 44.5 g aluminum case has a polished PVD finish and is equipped with an interchangeable bezel and a white fluororubber strap (140–210 mm). The 1.43-inch AMOLED display offers excellent brightness, with HBM peak brightness up to 1500 nits and a 60 Hz refresh rate. The watch supports Bluetooth 5.3, NFC payments (Mastercard & Visa*), and is compatible with the Xiaomi Smart Hub platform.
The fast and intuitive Xiaomi HyperOS 2 operating system includes a rotating crown and gesture controls. You can easily customize the watch face with interchangeable bezels. Bezel & Strap Kit options include Dual-Tone Ceramic (blue-grey), Pine Green, Midnight Carbon, Festive Orange and Liquid Silver.
Xiaomi Watch S4 measures your heart rate, stress, blood oxygen saturation and sleep with a single tap. It also includes a breathing exercise feature and a micro-physiological status report generated in about 60 seconds. Thanks to its 12-channel sensor module and custom heart rate algorithm, measurement accuracy reaches up to 98%.
Beyond its 150+ sport modes, the watch features dual-frequency GNSS (L1+L5) with five satellite systems (GPS, Galileo, Glonass, BeiDou, QZSS). It supports running coaching, posture analysis, ski mode and automatic fall detection. Workout results sync with the Mi Fitness app, and the watch also supports Health Connect, Strava and Suunto.
The watch can control Xiaomi Home devices, take remote photos, locate your phone, and manage headphones. Gesture controls allow you to reject calls and notifications, open the weather app or take a picture with a simple snap.
