iOS 15.4 - "massive" battery drain

Hi,

with the update to iOS 15.4 I experience a "massive" battery drain on my iPhone 8.

That means the battery of my iPhone 8 is empty within a few hours.

With iOS 15.4 I have to recharge my iPhone at least three times a day.

Are there any solutions yet how to tackle this battery drain issue which evolved with iOS 15.4?

Thank you.

iPhone 8

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?

Hi,

I just want to give an update with iOS 15.4.1.

Sorry to say that, but iOS 15.4.1 does not solve this battery drain issue on all my iOS devices currently.

Thank you.

Battery health (capacity) is the same but the iOS algorithm may have changed. It is an approximation and until it gets nearer to 80% you will not even notice.
