XPS 15 9570, BIOS update installed, battery issue

I am seeing sudden drop in my battery capacity since last bios update. Battery health says that it is just 9% and on Windows, even after the battery is exhausted and 0% remaining is displayed, XPS continues to work over hour and half.

I suspect the firmware has some issue - need advice on how to reset the battery to report correct capacity.
