Why does Huawei enjoy how fast it uses electricity?

Mobile phones consume a lot of power, so you can try the following methods:

1. screen closing and application settings: set the method, and then select settings > power saving management > protected background application, without checking the application marked as "high power consumption task" or selecting other unnecessary background tasks. After setting, the screen will automatically stop this power-consuming application.

2. Adjust the screen brightness: Setting method: Select Settings-Display-Brightness in turn, and adjust the brightness to reduce the value of the progress bar.

3. Restrain application traffic consumption: Set the method, enter Mobile Manager-Traffic Management-Traffic Ranking, and turn off "Mobile Data" and "WLAN" next to "All" to make them in a gray state.

4. Restrict the authority of the third-party application to reduce unnecessary operation and power consumption: the setting method, first of all, is Desktop > Mobile Manager > Authority Management > Cancel the "Read Location Information" authority of the third-party application, otherwise please disable it if it is not necessary.

If the above methods can't be solved, it is recommended to back up the important file data in the mobile phone and take the warranty certificate to the after-sales outlets for processing.
