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.

Exactly the same happened to my iPhone 14 Pro a couple of days after updating to 16.1.1. I lost 49% during the night. Checking the battery usage, Siri had 90% activity. I turned off "Listen to hey Siri" and since then the drainaged stopped. Not sure if turning off listen to Hey Siri was the solution or it was just Siri indexing a lot.

Turning off "Hey Siri" did not fix this for me. In the last 7 days I have only had the issue 2 times. The most recent being last night. Wake up, phone on wireless charger and very hot but charged to 100%. I take it off of charger and it loses 10% battery life in 1 hour. This time is was showing thet "home and lock screen" were using a lot of battery. I have no widgets and my screen was off

I've been having the same problem. My iPhone 13 Pro has been draining insanely fast and even I go to sleep and wake up again I see that it looses about 40% or more overnight (for about 8 hours).

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 phone do you have? as this only started since the most recent iOS update?

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

Yes.

but I need more time (one / two weeks) for testing to confirm that problem is indeed resolved.

Also on 13 Pro, fine if not better than on 16.2 at least anecdotally.
