💡

If you wear a bracelet on your right hand, change the side in the settings (Device Profile) → Wearing on the hand will improve the accuracy of the pedometer and pulse meter.

Don’t miss the screen section – you can set up here:

• 🔦 Brightness (optimally 3-4 levels for balance of visibility and autonomy).

Step 4: Finely adjusting activity tracking

Xiaomi Smart Band 4 can automatically recognize 5 types of activity: walking, running, cycling, swimming and elliptical simulator.
