Disable Lowering of Screen Brightness with Battery Drain in Windows 10

If you are using a Windows 10 computer that runs on batteries like a notebook or tablet computer, then you will notice that the screen brightness goes down a little when the battery charge level drops down to 20%. Windows does this to make the remaining charge in the battery to last longer than usual. Lowering the screen brightness does not matter much for most people, but if you always have the charger cable close at hand, then you can quickly plug it in and start to recharge the battery all over again. For such people, lowering of the screen brightness is nothing but annoying.

If you do not like this option and do not find it useful, then you can disable it in the following manner:

  1. Press the Windows logo key on your keyboard to open the Start menu and select the cogwheel icon to open the Windows settings.
  2. In the settings window, click on System to open the system related settings which include settings for the battery and how it is charged.Battery Saver
  3. Select Battery from the left side and you will see all the settings related to Battery Saver. You have to enable the Battery Saver if it is not already enabled.
  4. Uncheck the checkbox labeled Lower screen brightness while in battery saver.Battery Saver
  5. Close the settings window and you are all set.

The Battery Saver feature in Windows 10 is really useful for the notebook computers that often have a battery that lasts only 4-5 hours. With the help of this Battery Saver, you can have your battery last much longer. But if you get annoyed by the reduced brightness of screen when your computer goes into the battery saver mode, you can safely disable it. It does not impact how the battery saver works in Windows 10.
