If your Windows 11 device is running low on battery life—or you want to get the most out of every minute of power—you can turn on Battery Saver mode. Here’s how to do it.

What Is Battery Saver?

Battery Saver is a special Windows power-saving mode that squeezes more life out of your battery by dimming your screen brightness, reducing background activity, and limiting some notifications. It’s a lot like “Low Power Mode” on the iPhone and “Battery Saver” mode on Android. Windows 10 includes a Battery Saver mode as well.

By default, Battery Saver turns on automatically when your battery reaches 20% power or less, but that can be configured in Settings under System > Power & Battery. It will turn off automatically once you plug in your device to charge it again. Also, you can use Battery Saver manually any time you want to conserve battery life.

Turn on Battery Saver Using Quick Settings

The fastest way to enable Battery Saver is through the Quick Settings menu. To open it, click the hidden “Quick Settings” button in your taskbar—it’s located where you see the Wi-Fi, Speaker, and Battery indicator icons. Or you can press Windows+a on your keyboard.

When Quick Settings opens, click “Battery Saver.”

(If you don’t see “Battery Saver” in Quick Settings, click the pencil icon at the bottom of the menu, choose “Add,” then select “Battery Saver” in the list that appears.)

After clicking, Battery Saver will be enabled instantly. When you’re ready to turn it off, open Quick Settings again and click the “Battery Saver” button until it is no longer highlit.

Turn On Battery Saver in the Settings App

You can also enable (and configure) Battery Saver in the Windows 11 Settings app. To do so, first open Windows Settings by pressing Windows+i on your keyboard. Or you can search for “Settings” in the Start menu and click its icon when it appears in the results.

When Settings opens, click “System” in the sidebar, then select “Power & Battery.”

In Power & Battery settings, scroll down to the “Battery” section. Click the “Turn On Now” button located beside the “Battery Saver” option.

Battery Saver will turn on instantly. To turn it off again, click the “Turn Off Now” button beside the “Battery Saver” label.

While you’re on this screen, you can also choose the percentage at which Battery Saver will enable itself using the “Turn battery saver on automatically at” drop-down menu. That menu also includes an “Always” option for permanently keeping Battery Saver on and a “Never” option to disable it completely.

You can also toggle whether Battery Saver dims the screen using the “Lower screen brightness when using battery saver” switch. In general, keeping your screen brightness turned down will make a big impact in extending your PC’s battery life. Good luck!
