Surface customers with Pro 3’s and Pro 4’s know that these devices are still very valid. And, even more so now that we’ve seen Microsoft make only small, incremental changes between editions. In many cases, they are rock solid devices that just keep chugging along.
However, due to age, battery life can suffer. Microsoft is now rolling out firmware to hopefully help with that and to extend the life of these models.
According to new Surface docs…
Battery Limit option is a UEFI setting that changes how the Surface device battery is charged and may prolong its longevity. This setting is recommended in cases in which the device is continuously connected to power, for example when devices are integrated into kiosk solutions.
In the Surface doc, Microsoft shows how to access the BIOS for each device and toggle the option on. It also provides prescriptive guidance for enabling this new feature using the UEFI Configurator for Surface Pro 4 and supplied PowerShell scripts for Surface Pro 3.
The firmware is rolling out now through Windows Update.
