How to Enable Battery Limit Feature on Microsoft Surface

In this article, we will walk you through how to enable and verify the battery limit feature on supported Surface devices.

How to enable Surface Battery Limit feature

Starting in September 2018, Microsoft started rolling out a new feature called “Battery Limit” to all Surface devices starting from Surface Pro 3 forward. This feature can prolong your Surface’s battery lifespan by limiting the total charge to a maximum of 50%.

Enabling the setting preserves the battery’s ability to take and hold a charge while it’s connected to external power for an extended period of time and is recommended for Surface devices integrated into solutions like kiosks, consoles, and other scenarios where they are constantly connected to an external power supply.

The feature is being rolled out to Surface devices via the Firmware update. In this article, we will walk you through how to enable this feature on your supported Surface devices.
