iOS 16.1.1 Battery Drain Issues on iPhone

iPhone 14 ProMax battery life has significantly come down, and I'd call it poor after updating to iOS 16.1.1 a couple of days back. 16% battery drain overnight in 7 Hours with no usage.

And almost 20% battery drain with 22 mins usage!

I tried to restart, force restart, and minimise the background app refresh (limited the number of apps from what it was in 16.1) - all ended up being futile.

Apple support ran a diagnostics and confirmed no issue with Hardware. Several people report similar problems and wonder if Apple engineers will acknowledge this and provide a fix.

Does anyone have any more suggestions?

Very poor for a premium product! Extremely disappointed.

Unfortunately the same behavior on 16.1.2 software in my case (can someone confirm too?).

Does it also happen on non Pro / Pro Max devices?

16.2 version should be available on december 2022

Called Apple Support but that was awaste of time (as expected) they also said they never heard of this issue and that they have no prior reported cases

What is odd, It doesnt always have this issue. Sometimes it will go the whole day with good battery life and no excess heat. Then days like today... it is horrible
