my battery is draining very fast at bh 95%
(i got my iphone second hand, but it’s pretty much new as i got it with battery health 96%) up until two to three days ago my battery had been just fine running for about a few hours while using it all the time. last night i left it (around 2am) and it was at 93%. i woke up this morning to find it at 81% and after using it for about 20 minutes it had dropped down to 71%. is there some issue with the battery and should i worry?
