Enable USB Battery Saver in Windows 11 by opening Settings, navigating to Bluetooth & devices, clicking USB, and toggling the USB battery saver option on. This feature conserves power by cutting electricity to idle USB devices when your screen turns off.
Is USB battery saver enabled by default in 🪟 Windows 11?
Yes, Windows 11 often enables basic power management features by default to optimize system latency and battery life. However, depending on your laptop manufacturer’s power delivery profiles, you may need to adjust these settings manually to balance performance with longevity.

Steps to disable power management for a specific device (Requires Admin Privileges):
- Right-click the Start button and select Device Manager.
- Expand Universal Serial Bus controllers.
- Right-click your USB Root Hub and select Properties.
- Go to the Power Management tab and uncheck Allow the computer to turn off this device to save power.
USB4 and Power Delivery
Modern devices supporting USB4 80Gbps require stable power delivery profiles. While USB battery saver is great for basic peripherals, high-performance docks and external GPUs may require consistent power. Always check the official Microsoft USB documentation for compatibility details.
Pro-Tip: Prevent Windows from turning off USB ports
If you have a device that keeps disconnecting, navigate to the Device Manager, find the device under Human Interface Devices, and uncheck the power saving box in the Power Management tab to keep it active at all times.
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.
Does USB battery saver affect gaming mouse performance?
Yes, it can. If the system cuts power to your USB port, your gaming mouse may experience input lag or disconnect entirely when the screen goes dark. For competitive gaming, it is recommended to disable power-saving features for your specific USB ports to ensure consistent peripheral latency.
Why does my keyboard disconnect after enabling USB power saving?
This happens because the power management system incorrectly identifies your keyboard as an idle device. When the screen turns off, Windows suspends the USB port to save energy. You can fix this by disabling the power management setting for that specific device in the Device Manager.
