How to Enable or Disable Battery Limit on Microsoft Surface Devices

This tutorial shows you how to turn the Battery Limit option on or off on your Microsoft Surface device running Windows 10 or Windows 11.

What is Battery Limit?

The Battery Limit option is a firmware setting on your Surface device. Think of firmware as the instructions that tell your device how to work at the deepest level. This setting changes how your Surface battery charges. It might help your battery last longer.

Battery Limit works best for Surface devices that stay plugged in all the time. These include devices used as cash registers, security scanners, and information kiosks. The Battery Limit setting comes built into supported Surface devices by default.

Why Would You Use This?
