Here Some Tips on How to Increase Your Battery Backup:
1.Screen Brightness-
Keep your Brightness Level to 30-40%.
Most of the people use automatic brightness to save the battery but in fact it doesn’t. Here the explanation-When we set our screen brightness to Auto,then the Ambient Light Sensor gets activated and it continuously checks to see if there is some changes in the light to our surroundings so that it can manage and change screen brightness according to the surroundings.If it sense change in light (which changes very often) then it will send the signal to our CPU and the CPU will do some calculation and change the screen brightness accordingly. More Changes in Light,More calculation And More Eating of Battery. Therefore It is important to keep your Brightness Level to 35-40% which is convenient to look the screen in most cases and saves the battery resources a lot.
2.Set Black Wallpaper.
