When the power consumption of the mobile phone is fast, you can optimize the mobile phone first, but there is still no improvement after optimization.

Click phone manager > xx% remaining > for the protected application, uncheck the check box for not running the application in the background.

2. Please adjust the brightness of the screen.

Go to Settings > Display > Brightness and lower the value of the brightness progress bar. In the battery management of mobile phone housekeeper, you can use the page to check the battery charge. Make reasonable settings according to the usage scenario.

3. Clear unnecessary applications in the background.

Click the box key in the navigation bar, and then click the Clear key to clear applications that are no longer needed. Some super applications, such as QQ and WeChat, cannot be closed in this way. If you want to close the Super app, click Mobile Manager > Battery Management >; Power consumption firewall (background power consumption application).

4. Uninstall some unnecessary high-power applications.

Go to Settings > Advanced Settings > Location Services to see if there are any high-power applications below. It is recommended to uninstall the infrequently used high-power applications.
