Why sync your smartwatch with your phone and what it does
Xiaomi’s smartwatch is not just an accessory, it’s a full-fledged assistant for tracking health, managing notifications, and even paying for purchases. But without properly synchronizing with an Android smartphone, it’s minimal: you’ll only get time and pedometer. Connecting to your phone unlocks the full power of the device.
After successful binding, you will be able to:
- 📱 Receive notifications from messengers, social networks and mail directly to the screen of the clock.
- 🏃♂️ Track pulse, sleep, stress levels and other health metrics with synchronization in Mi Fitness (formerly Zepp Life).

- 🎵 Control music on your phone right from the clock - switch tracks, adjust volume.
