In September 2018, Microsoft started rolling out a new “feature called “Battery Limit” “Battery Limit” feature to all Surface devices, beginning from Surface Pro 3 forward. This feature can prolong your Surface’s battery lifespan by limiting the total charge to 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.
Microsoft Support
The feature is being rolled out to Surface devices via the Firmware update. This article will walk you through enabling this feature on your supported Surface devices.

Let us know what you think!
We appreciate hearing your thoughts, questions, and ideas about “How to Protect Your Surface Battery with Battery Limit Mode”.
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!
If you discharge the keyboard below 50%, then it also has a limitation, as well as on the main screen part. For some reason, they write everywhere that it does not have such a function, although it does exist)))
Hi Evan, do you know how to change the battery limit to above 50%?
The 50% limit is too low for me.
I have double-checked the Microsoft support documents site, Currently, there is no way to set a custom battery limit on Surface devices yet.
Why is this feature absent in Surface 8 Pro?
Works on Surface 8 Pro.
However, it would be perfect if you could set it at 75% or so. Would preserve battery life without negatively impacting it’s use as a mobile device – 50% is a bit low. Of course, you can always shut it off when you’re travelling and expect you’ll be working away from a charger.
Thanks Evan , to prolong the battery lifespan whe to recharge the battery until flat at 0? Or top up when it below 20%?
Thanks
