With the latest update, Surface Pro 9 owners received patches for a problem with their devices unexpectedly shutting down due to inaccurate battery life estimation. Nothing ruins a day more than watching your computer abruptly die with a 30% battery level.

Here is the official changelog:

The following update is available for Surface Pro 9 with Intel Processor devices running Windows 10 October 2022 Update, Version 22H2 or greater.

 

Improvements and fixes:

Here is extra information about the release:

Your Surface Pro 9 will download available updates automatically, but you can speed things up by heading to Settings > Windows Update and clicking the "Check for updates" button. Alternatively, go to the official Surface support website and download a manual installation package. As usual, remember to back up important data before updating firmware since Microsoft does not allow undoing Surface firmware updates. Better safe than sorry.

All Surface Pro 9 configurations have a six-year lifecycle, which started on October 25, 2022, and will end on October 25, 2028.
