Enable or Disable Battery Saver in Windows 11

Battery Saver in Windows 11 automatically reduces background activity and lowers screen brightness to extend your laptop’s battery life. This guide shows you how to turn it on or off manually, set it to activate automatically at a chosen battery percentage, and adjust related settings. No special tools are needed—everything is done through the built-in Settings app.

What You’ll Need

A laptop or tablet running Windows 11 (version 22H2 or later recommended).
Your device must be running on battery power—Battery Saver cannot be manually enabled while plugged in, though you can still adjust its automatic trigger settings.

Step-by-Step

Open Settings. Press Windows + I on your keyboard, or click the Start button and select the gear icon.
Go to System > Power & battery. In the left sidebar, click System, then choose Power & battery from the list.
Find the Battery Saver section. Scroll down until you see Battery saver. You’ll see its current status (e.g., “Off” or “On”).
Turn Battery Saver on manually. Click the Turn on now button. It will immediately enable Battery Saver until your battery reaches 100% or you turn it off manually.
Turn Battery Saver off manually. While Battery Saver is active, the button changes to Turn off now. Click it to disable Battery Saver and resume normal background activity.
Set automatic activation. Click the Battery saver row (or the chevron arrow) to expand its settings. Use the dropdown under Turn battery saver on automatically at to choose a battery percentage (e.g., 20%, 30%, 50%).
Adjust automatic brightness lowering. In the same expanded section, check or uncheck Lower screen brightness while in battery saver depending on whether you want the screen to dim when Battery Saver is active.
Close Settings. Your changes are saved automatically. Battery Saver will now behave as you configured.

Common Mistakes

Trying to enable Battery Saver while plugged in: Windows grays out the “Turn on now” button when the device is connected to AC power. Unplug the charger to enable it manually.
Confusing Battery Saver with Energy Saver: Windows 11 also has an “Energy saver” feature (introduced in version 23H2) that works on both battery and plugged-in devices. Battery Saver is the older, battery-only feature. They are separate toggles.
Expecting immediate battery percentage changes: Enabling Battery Saver does not magically increase your battery percentage; it slows down the drain rate by limiting background activity.
Overlooking the automatic threshold: If you set the threshold to 50%, Battery Saver will turn on at 50%—but only if you haven’t manually turned it off since. Manual off overrides the automatic setting until the next time you plug in and unplug.

Tips

Use the quick action toggle: Click the battery icon in the system tray (bottom-right corner) and then click the Battery saver button to toggle it on/off without opening Settings.
Customize the automatic threshold: Set it to 30% for everyday use to balance performance and battery life. Use 50% if you know you’ll be away from a charger for a long time.
Keep an eye on which apps are affected: Battery Saver limits background apps and notifications. If you rely on email sync or messaging, you may miss updates while it’s on.
Combine with other power settings: For maximum battery life, also reduce screen brightness manually and close unused apps. Battery Saver works best when you’re not actively gaming or editing video.

Troubleshooting

Battery Saver won’t turn on manually. Ensure your device is unplugged. If it’s still grayed out, restart your laptop—sometimes the power settings get stuck. Also check that you’re using a recent version of Windows 11; older builds had bugs with this toggle.

Battery Saver turns on unexpectedly. Check the automatic threshold—it might be set higher than you remember. Also, some apps or power plans can trigger it. Go to Settings > System > Power & battery and confirm the threshold is where you want it.

Battery Saver doesn’t seem to do anything. It doesn’t stop all background activity—it limits it. If you have many apps set to “Always run in background” in their own settings, they may still consume power. Check individual app settings under Settings > Apps > Installed apps.

The Battery Saver option is missing entirely. This can happen on desktop PCs without a battery, or if your device’s driver doesn’t report battery status. Try updating your battery driver via Device Manager (right-click Start > Device Manager > Batteries > update driver). If your device is a desktop, this feature simply isn’t available.

Frequently Asked Questions

Q: Does Battery Saver damage my battery?
A: No. It only reduces power consumption. It does not affect battery health negatively; in fact, it can help you avoid deep discharges if you set the threshold higher.

Q: Can I set Battery Saver to turn on automatically at 80%?
A: Yes. In the Battery saver settings, choose “80%” from the dropdown. It will activate at 80% battery when you’re unplugged.

Q: Will Battery Saver stop my notifications?
A: It may delay or suppress notifications from apps that run in the background. You’ll still get notifications from apps you’re actively using.

Q: Why is the “Turn on now” button grayed out?
A: Your device is likely plugged into a charger. Battery Saver only works on battery power. Unplug the charger and try again.

Q: Does Battery Saver affect performance?
A: Yes, it can lower CPU performance and reduce screen brightness. For most tasks like web browsing or word processing, the impact is minimal.

Q: Can I use Battery Saver on a desktop PC?
A: No, Battery Saver is designed for devices with batteries. Desktops typically don’t have this option in Settings.
