I still think something is wrong with the battery. I had my iPad on the charger overnight and it had a full 100%, then I used it for about 30mins this morning watching Netflix while exercising. Battery went from 100% to 95%. Then, killed every app in the background, and left it sitting off at home while I went to work. Checked it now at 8pm, and it’s below 80%, with no one touching it during the day. And looking at the battery usage screen, it says it’s been used for 11 hours since last full charge, even though it was only used for 30 mins and then sat the rest of the time.
35 minutes of on screen time would normally consume 7-10% of my battery. So that leaves 15% unaccounted for. It’s a beta. Accounting complete.
