Battery drain after upgrading to iOS 15.5 - iphone 12 pro max

After upgrading to iOS 15.5, I experienced a battery Health drain from 95% to 89% in only 49 days.

It once dropped from 93% to 91% in one day.

I always make sure to charge my phone between (80% and 25%).


Has anyone experienced the same?

is there any solution for this problem maybe downgrading to 15.4 ?


Thank you
