Battery Optimization: How to Extend Your Life to 20 Days
Officially, the Mi Band 3 holds a charge of up to 20 days, but in practice, users experience a discharge in 5-7 days. The main "eaters" of the battery are constant synchronization, auto-measurement of pulse and backlighting of the screen. We tested several ways and found the optimal settings for maximum operating time.
Top.-5 battery-saving:
- 🔋 Turn off the Permanent Time Display (Mi Fit) → Display settings. Savings: +7 days.
- 📵 Reduce the frequency of automatic pulse measurement to 1 time per hour (Mi Fit) → Heart rate. Savings: +5 days.
- 🔔 Turn off vibration for unnecessary notifications (e.g. from games or news apps: +2 days.
- 🌙 Turn on Sleep Mode for the Night (Mi Fit) → Son → Sleep mode. Savings: +3 days.
- 🔄 Turn off automatic data synchronization (leave manual only: +4 days.
Critical information: If the bracelet discharges in 1-2 days even after optimization, the problem may be a faulty battery. Check its condition at the service center - Xiaomi sometimes replaces the batteries under warranty even 2-3 years after purchase.
Also pay attention to the temperature regime:
- ❄️ At temperatures below -10°C battery goes down 2 times faster.
- ☀️ Higher temperatures +40°C (for example, in a sauna) bracelet may be turned off.
Only include notifications that are really important.
Use manual pulse measurement instead of automatic pulse measurement.
Turn off the permanent lighting, but leave the gesture of "raise of the hand."
- Synchronize data 1-2 times a day manually.-->
