Go to Settings > Show > brightness and decrease the value of the brightness progress bar.

2. Clear unnecessary apps in the background.

3. Uninstall some unnecessary high-power consumption applications.

5. Turn off the function that is not in use temporarily.

Turn off features that are not in use for the time being, such as Wi-Fi, GPS, Bluetooth, mobile data, NFC, etc. It is recommended to turn off the vibration function and turn off data synchronization.

6. Check whether the signal is normal. If the signal is weak or absent all the time, it can also lead to high power consumption.

If there is no 4G signal or the signal is weak, it is recommended to turn off the 4G switch to prevent frequent network switching and power consumption.

7. Upgrade your phone to the latest version. The new version improves the stability and user experience of the system, and optimizes some known issues.

If there is still no improvement after optimization, you can try to back up important data and try to restore factory settings. If it is still invalid, bring the purchase invoice to the Huawei Service Center for testing.
