How to Enable USB Battery Saver in Windows 11

Is USB battery saver enabled by default in 🪟 Windows 11?

Sometimes. Windows 11 often enables basic power management features by default to optimize system latency and battery life. Your laptop manufacturer’s power delivery profiles can change that, though, so the setting on your machine may differ from the default.

Open the USB page in Settings (covered below) and look at the toggle. If it is off and you want longer battery life, turn it on. If you rely on a device that must stay powered, you may need to adjust the settings ⚙️ manually to balance performance with longevity.

How to change USB battery saver settings

You change USB battery saver settings in the main Settings app ⚙️, under Bluetooth 🔷 & devices. This built-in feature helps your laptop battery last longer by reducing the power sent to connected USB accessories when you are not plugged into a wall outlet.

The steps are the same on Windows 11 Home and Pro. The USB page and its battery saver option appear on some PCs and not on others, depending on your hardware and Windows 11 version. If you cannot find it, see the notes after the steps and use the Power Options method in the next section instead.

1. Open Settings by pressing the Windows key + I on your keyboard. The Settings window opens with a list of categories on the left.

2. 

3. In the menu on the left, click Bluetooth & devices. The right side now lists your paired devices and related options.
4. On the right side of the screen, click the USB tile. You may need to scroll down to see it. A page with USB options opens.

5. 

6. Find the USB battery saver option and toggle it On or Off. The switch changes right away. There is no Save button and you do not need to restart.

Advanced Power Management: USB Selective Suspend

USB Selective Suspend is a power management feature in Windows 11 that helps conserve your laptop battery. It works by putting unused USB ports into a low-power state so they stop draining energy when your devices are plugged in but not actively being used.

This setting lives in the older Power Options window, and it is set per power plan. It is also the place to look if the USB page in Settings does not show a battery saver option on your PC. Changing it needs an administrator account. If you are on a standard account, Windows will ask for admin credentials.

Steps to access legacy Power Options (Requires Admin Privileges):

1. Press Windows key + R, type powercfg.cpl, and press Enter. The Power Options window opens in Control Panel.
2. Click Change plan settings next to your active power plan. This is the plan with the filled-in selection circle.
3. Click Change advanced power settings. A small Power Options dialog opens with a list of settings you can expand.
4. Expand USB settings and then USB selective suspend setting. You will see entries for On battery and Plugged in.
5. Set each entry to Enabled to let Windows suspend idle USB ports and save power, or to Disabled to keep them powered all the time.
6. Click Apply, then click OK. The change takes effect immediately, so you do not need to restart.

To undo the change, repeat the steps and set the value back. If you use more than one power plan, check each plan, because the setting does not carry over between them.

Troubleshooting USB Connectivity Issues

USB devices frequently disconnect in Windows 11 when the operating system cuts power to save battery. You can fix this common connectivity problem by changing your device power management settings in Device Manager to stop Windows from turning off your hardware automatically.

The usual signs are a mouse that stops responding after a pause, a drive that vanishes from File Explorer, or a headset that drops out and comes back. If you see these after turning on USB battery saver or selective suspend, this fix is the next thing to try.

Steps to disable power management for a specific device (Requires Admin Privileges):

1. Right-click the Start button and select Device Manager. The Device Manager window opens with a list of hardware categories.
2. Expand Universal Serial Bus controllers. You will see a list of USB controllers and hubs.
3. Right-click your USB Root Hub and select Properties. Many PCs list more than one root hub, so you may need to repeat these steps for each one.
4. Go to the Power Management tab and uncheck Allow the computer to turn off this device to save power.
5. Click OK to save the change. No restart is needed.

The trade-off is a little more battery use, because that hub stays powered. To undo it, open the same tab and tick the box again. If a device's Properties window has no Power Management tab, Windows does not let you control power for that item, and you can skip it.

USB4 and Power Delivery

While USB battery saver is great for basic peripherals like mice and keyboards, high-performance docks and external GPUs may require consistent power. If one of these keeps dropping out, turn the battery saver and selective suspend settings off and test again. Always check the official Microsoft USB documentation for compatibility details.

Pro-Tip: Prevent Windows from turning off USB ports

If you have a single device that keeps disconnecting, you can stop Windows from powering it down without changing the setting for every USB port. Follow these steps:

1. Open Device Manager and navigate to Human Interface Devices. Mice, keyboards and similar devices are listed here.
2. Double-click the device that keeps dropping out to open its properties.
3. Go to the Power Management tab and uncheck the power saving box to keep the device active at all times.
4. Click OK. The device should now stay connected when idle.

Some devices appear under a different category, such as Universal Serial Bus controllers or Disk drives, so look there if you do not see yours. To undo the change, tick the box again.

Summary

The USB battery saver in Windows 11 is a straightforward way to help your laptop battery last longer by stopping power to USB devices when not needed. Turn it on in Settings › Bluetooth & devices › USB, or use USB selective suspend in Power Options if the toggle is missing.

If a device starts disconnecting, turn off power management for that device in Device Manager. You can reverse any of these changes at any time.
