iOS 15.4 Battery Drain
Is anyone experiencing battery drain since updating their iPhone to iOS 15.4? I am considering updating this morning and have seen this be an issue with other updates in the past.

15.4.1 is out.
"This update includes the following bug fixes for your iPhone:
Battery may drain more quickly than expected after updating to iOS 15.4"
So I guess it wasn't all just temporary reindexing and would get better in 48 hours.
Apple's engineers are smart. I'm sure they knew they had a genuine problem within hours of 15.4's release. These bugs that only manifest for certain configurations of hardware and software can be hard to find and hard to fix. I understand that, and would cut them slack for it. It's the denial and obfuscation that diminish my respect for Apple. Why not just acknowledge there's an issue and tell us they're working on it?

Yes . Many 12 series users says battery life is not good
I have the 13 pro max and I also noticed that the battery got worse
YES, rapid drain.
I've an iphone 12 mini bought 7 month ago and after I've have update (ios 15.4) battery drain is very visible. In one night it has lose 5% of battery. (4g disable and wifi abilitate). Any solution?
Yes! My 13 Pro Max battery is draining very quickly and the phone is warm. That's used to be an issue with 12 Pro Max but not with the new model until 15.4 update
Huge difference at my 12 pro max. I am very disappointed.
UnPair/Pair, Power Cycle, wait for any indexing actions to complete and any other obvious step was performed well before this report was issued.
That was the first step! This was to provide support for the rest of the iOS Community.
iPhone 13 user here. Got an update last night and the battery drain is noticeable. I used to have no less than 30% by midnight and now it’s at 22% by 8 pm already. Hope there will be a quick fix.
Yes …. I am experiencing battery drain much quicker than before in my 13 pro max.
my 13 pro max is 1 month old. It could go full day of heavy usage with 50% battery. After update, close to 50% battery drain in 6 hours with light usage, youtube and messenger.
Yes. 15.3 was way better. Any method that I can downgrade to 15.3?
hey, have a iphone se (2020) here did the update from ios 13 to 15.4 yesterday. batterie goes from 100 to 8% in about 2h. the phone just lay here, no touching, batterie gets sucked out.
I can ensure there is two hours less backup after iOS 15.4 on my 13 max
