How to Enable USB Battery Saver in Windows 11

This guide explains how to manage the USB battery saver feature in Windows 11.

Windows battery saver helps your laptop run longer. It does this by dimming the screen, limiting notifications, and stopping background tasks. You can also set your computer to turn off power to USB devices whenever your screen goes dark. This prevents external gadgets from draining your battery while you are away from the computer.

Why use this feature?

External devices like mice, keyboards, and drives pull power from your laptop. If your battery is low, these gadgets will drain it even faster. Enabling this feature keeps your battery healthy for longer periods.

What happens when you enable it?

Once enabled, Windows will automatically cut power to your USB devices the moment your screen turns off. This prevents unnecessary power loss.

How to change USB battery saver settings

You can manage this through the Windows Settings menu. You do not need admin privileges for these steps.

1. Open Settings by pressing the Windows key + I on your keyboard, or by clicking Start and then Settings.

2. In the menu on the left, click Bluetooth & devices.
3. On the right side of the screen, click the USB tile.

3. Find the USB battery saver option.
4. Click the toggle switch to turn it On or Off.

Summary

The USB battery saver is a simple tool to help your laptop battery last longer. By turning off power to USB devices when your screen is off, you stop unnecessary battery drain. You can easily toggle this setting on or off by navigating to Settings > Bluetooth & devices > USB.
