How to Change Brightness When Battery Saver is On in Windows 11

What is Battery Saver?

Battery Saver is a Windows feature designed to help your device conserve power when running on battery. It achieves this by disabling or slowing down certain features, allowing your battery to last longer.

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

How Does Brightness Change?

When Battery Saver is active, Windows typically reduces your screen brightness by roughly 30% to conserve power. However, you have the flexibility to make it brighter or dimmer to suit your preference. You can even disable this automatic brightness adjustment entirely.

Important Notes:

• Battery Saver only works when your device is running on battery power (not plugged in).
• When you plug your device in to charge, Battery Saver automatically turns off and your brightness goes back to normal.
