How to turn off the battery saver in Windows 10

When the battery saver is enabled in Windows 10, the screen's brightness is set to a low level, and the background activity, and push notifications are disabled to save energy. The battery saver is enabled automatically by Windows 10 when the battery level below 20% or a custom level set by the user.

The best way to turn off the battery saver is to plug your Windows 10 laptop or tablet into a power outlet. As soon as Windows 10 detects that your device is charging, it should stop using the battery saver.

Another way to turn off the battery saver is to click or tap the battery icon in the bottom-right corner of your desktop. The power slider should be found on the left margin. Move the slider to the right, to any other position, and the battery saver is disabled.

If you did this, and the battery saver is still turned on, then your battery may be at a critical level, under 20%, and you should charge your Windows 10 laptop, or tablet. However, you can still disable the battery saver, by unchecking the option that says: "Turn battery saver on automatically if my battery falls below."

If you want to personalize how the battery saver works, open Settings and go to System.

In the column on the left, choose Battery, and then look for Battery settings on the right. Besides the switch that turns the battery saver mode On and Off, you have other settings too. For instance, you can choose when the battery saver is turned on automatically. By default, it is set to activate when your battery is at 20% of its charging capacity, but you can change it to whatever level you want, by moving the slider. If you do not want the battery saver to turn on automatically when the battery reaches a particular point, uncheck the box next to "Turn battery saver on automatically if my battery falls below," and it is never going to turn itself on automatically. Secondly, the battery saver also includes an option for dimming the screen brightness so that less energy is being consumed. If you check the "Lower screen brightness while in battery saver" setting, when the battery saver turns on, your display is dimmed automatically.
