This is terrible. It's a good thing that I'm not in desperate need of my Pro 2.
The SP2 won't charge while connected to power. The battery level is stuck at 16%.
This firmware update totally killed my device.
Mbytes posted this in another thread, and it worked for me. My battery now displays the correct percentage.
It's a miss read of the battery circuit. Microsoft is looking into the issue, but there is a fix, apparently the following works:
1. Shut down.
2. Hold volume Up (+) button and power button for 15 sec. Surface logo may flash, but don't let go for 15 sec.
3. Let go of both buttons after 15sec.
4. Wait 10 secs.
5. Press power button to start up.
