Find the phone setting function in the phone's main interface, and then click Settings to enter the phone setting interface.
Then in the phone settings interface, slide down until you see the battery settings option, and then select the battery option.
Then enter the battery setting interface, and there is an option to display the percentage of remaining power at the top of the battery setting.
We only need to turn on the option of displaying the percentage of remaining power, and we can see the consumption of the battery of the mobile phone.
