This guide will help you turn on or off the option to lower your screen brightness when Windows 11 is using Battery Saver mode.

What is Battery Saver?

Battery Saver helps your laptop or tablet save power when it’s running on battery. When it’s on, Windows reduces some features to save energy and help your battery last longer.

By default, Battery Saver turns on automatically when your battery goes below 20%.

What does lowering screen brightness mean?

Your screen brightness will automatically dim by about 30% when Battery Saver is active. This helps save battery power because the screen uses a lot of energy.

You can change how much the brightness lowers or turn this feature on or off completely.

Important things to know

• Battery Saver only works when your device is running on battery, not when plugged in.
• It turns off automatically when you plug your device in to charge.
• If you like watching HDR videos (high-quality videos with bright colors), you might want to turn off lowering brightness, so the screen stays bright for the best picture.
