Surface Tip: How to enable Battery Limit feature on Surface devices
In this article, we will walk you through how to enable and verify the battery limit feature on supported Surface devices.
Starting from 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.

So it’s NOT available for the Surface Pro 6 then….🤦♀️
Battery one will be capped with 50% on SB2 but battery 2 will continue to be charged to 100%.
Does this not entirely counteract the whole purpose of Battery Charge Capping? With this configuration, you will save the lifespan on the base section and end up with a dead battery on the tablet.
But the tablet section will not be replaced or repaired, all you can hope for is a lousy refurb.
Microsoft, Microsoft – can’t you get anything right? And to think it took a whole bl**dy year to serve us this crap.
Hi Patrick, I’m really sorry and thanks for pointing that out. This is my mistake, I’ve double-checked on my Surface Book, and it appears that the Battery 1 is for tablet’s section and Battery 2 is for the keyboard base. I’ve updated the article with the right info. Thanks!
