Microsoft releases battery life update to Surface Pro 3 and Surface Pro 4

Microsoft has released a UEFI firmware update to the Surface Pro 3 and Surface Pro 4 which will include a new Battery Limit feature designed to extend the life of the lithium-ion batteries that power the tablets.

Once this update is installed, users will be able to toggle an option that will stop the battery on these tablets from charging when it reaches 50% of its capacity. If the battery is already charged to more than 50% capacity when the tablet is plugged in, Battery Limit will force the battery to discharge until it is down to 50% of capacity.

According to Microsoft, this Battery Limit feature is made for Surface Pro models that are plugged in most of the time. The company used Surface Pro unit could be constantly hooked up to an outlet at retail stores as an example of where this feature can be used. While the feature is currently available for the Surface Pro 3 and Surface Pro 4 only, Microsoft plans on adding it to other Surface Pro models in the future.

On the Surface Pro 4, you can toggle Battery Limit by booting into Surface UEFI (Power and Volume up when turning on the device). Select Boot Configuration > Advanced Options and toggle Enable Battery Limit Mode to On. Surface Pro 3 users can access their Surface UEFI by heading to Kiosk Mode > Battery Limit > Enabled.
