Battery drain after 15.1 on 12 pro max
Dear,
My iphone 12 pro max had had outstanding battery life before I updated to ios 15.1.
Now it is under every serious level,totally unacceptable and terrible.
I am using the phone in the same way as prior your update.
Please have this serious issue fixed as soon as possible.
Please do not send me standard battery usage advice and work on the solution.
Thanks in advance
iPhone 12 Pro Max, iOS 15
