iOS 15.5 update drains Iphone 13 Pro battery
I have an Iphone 13 Pro. After updated it to iOS 15.5 the phone begun to drain the battery very quickly. With iOS 15.4.1 I finish the day with 50% charge, and now 7% (the use did not change).
Also note that the Phone is warmer sometimes.
Phone has 6 months of use and battery condition is 100%.
How can I fix the problem? going back to 15.4.1?
