If it isn’t already obvious, it’s important to note that locking your screen to a higher brightness level will dramatically increase battery usage, so make sure you pick a nice balance that won’t chew through your battery supply. If you don’t need max battery life feel free to set it to whatever you like.

To begin, open Settings then navigate System, then finally Battery. Under the Battery settings section, you will see a subtle checkbox with the text: Lower screen brightness when in battery saver next to it. Simply remove the tick from this checkbox and Windows will make sure your screen brightness remains the same when connected to power and when running on battery.



You can also lock your screen brightness to the same level by doing the following. Right-click the battery icon in the system tray, then and click Power Options. This will open a new window where you will need to click Choose when to turn off the display.


Finally use the screen brightness slider to set your screen brightness levels for power and battery modes. Just remember that this will only affect the current power plan. If you switch plans, you’ll need to readjust your settings.
