How to use

Charge the band using the supplied charger until the battery is sufficiently charged (fast charging reaches a usable level in about 1.25 hours). Install the Xiaomi wearable app on your smartphone and pair via Bluetooth to enable full functionality, GNSS tracking and sport modes. Wear the band snugly on your wrist for accurate heart rate, SpO2 and sleep measurements. Select sport modes or enable automatic recognition before workouts for best results. For outdoor routes, start a GNSS activity to record precise positioning without carrying the phone.

Recommendations

For accurate heart rate and SpO2 readings, wear the band above the wrist bone with moderate tension and keep the sensor area clean. Enable automatic sleep tracking and allow the device to collect multiple nights of data for more consistent sleep analysis. Rinse and dry straps after exposure to sweat or water, and use the quick-release mechanism to swap straps according to activity or style.
