iPhone 13 Pro Max battery health decline after iOS 26 update Ever since i have upgraded to ios 26 in the iphone 13 pro max. The battery health is constantly dropping. Last month i had 84% battery health and now it is showing 76%. Even though i charge the phone only once in a day. This is not an expected battery drop that should be experienced in any device.

Ios26 has destroyed my battery life! my battery has lost at least 30 percent of its capacity by using ios 26. Started on the day I downloaded it, no other changes, on a iphone 16 pro max. never experienced this before and very disappointed. I used to make it through the day no problem but now I can’t even make it 3/4 through the day without the battery being drained!
