What this smartwatch is and who it fits

The Mi Watch S3 is a 1.43-inch AMOLED smartwatch in silver with a rubber band. It runs HyperOS and is compatible with Android phones. The 47 mm aluminium alloy case weighs 44 grams and carries a 5ATM waterproof rating. Sensors include accelerometer, gyro, compass, barometer, heart rate and SpO2 monitoring.

Practical limits of the Bluetooth 5.2 connection

Bluetooth 5.2 with A2DP and LE handles phone notifications, music control and data sync. There is no Wi-Fi, no WLAN and no USB port, so all communication goes through the paired phone. NFC is present but market-dependent, and the loudspeaker handles calls and alerts without a 3.5 mm jack.

Check your phone and region before ordering

The watch requires an Android device for full HyperOS features and GPS tracking using L1+L5, GLONASS, GALILEO, BDS and QZSS. NFC payments may not work in every region. There is no microSD slot and the 486 mAh battery is non-removable, so daily charging access is needed.
