In case you haven’t downloaded the update yet, go to Settings > Update & Security > Check for updates and download the latest firmware available for the Surface Pro 3.
Before installing the update, plug your Surface Pro 3 into AC power using the standard AC power adapter, and disconnect any USB devices or external monitors. Peripherals may cause update issues and it’s best to disconnect any external devices before installing it. Once you install the update, restart your device a second time to complete the install process.
According to users, the new firmware update has indeed improved battery life for the Surface Pro 3, but there’s still a lot of work to do before all battery degradation issues are completely eliminated.
This isn’t a 100% recovery to where I was before all this started but I am, with a huge relief, finally typing this on battery with 100% charge and 5 hours 28 minutes estimated time remaining (seems to be stuck on that so perhaps the full charge capacity will recover further after a few cycles.
Interestingly enough, the battery indicator values are the same for all users after installing the update. The fully charged capacity remains at a constant 34,200 mWh level.
Thanks to this update, Surface Pro 3 owners have been able to let their devices use battery power for the first time in months. At the same time, the update helps users save money, as they no longer have to pay $500 to get a new battery for their Surface Pro 3 devices.
