The battery on my 2020 11” iPad Pro is draining battery insanely fast. It doesn’t matter what I am doing. Games, Safari, MR, Facebook, mail, everything. It simply will not hold a charge for 2 hours and zeroed out. 9 months old. I force quit every app before opening a new one and it is still happening. I believe it started when I updated to 15.2. Any suggestions would be helpful.
