Same, although I have had every iPhone since the 3G. This is for sure the first time I have gotten worse battery life after upgrading. Well more iOS 16 has ruined everything. I can remember battery life that was just the same as the prior model, but never worse. Really disheartening.

"Disheartening". Nice. That sums up my feelings perfectly. That, and some not insignificant level of annoyance.

Yep, it seems everything is gonna be blamed on the AOD, but I have had this issues with my 13 PM on the betas and then full version before I had the 14 PM. It’s definitely something deeper with iOS 16, and Apple is either ignoring it, or can’t figure it out.
 
I called Apple Support about my rapid battery drain and device overheating (it was the latter issue that prompted me to call Support). They recommend I replace the battery (at my own expense).

Fwiw, it’s at 95% capacity (was 97% a few weeks ago), and had no issues before the iOS upgrade.

To modify the above (and soften the blow a bit) – I got a voicemail with different instructions: they recommend I bring the phone into an Apple Store for "inspection and additional troubleshooting." Not the most convenient thing to do, but I suppose better than what was at the link they sent.

Finally getting there.

Are y’all using 5G or sticking with LTE? Is 5G still a battery hog?
 
The two things that I'm definitely seeing as drains on my 14P are

1) the 2000nits max on the screen.
2) the camera

I can definitely identify the down slope when both of those have been well used. Which is a shame as both are features that I upgraded for.

Yes the AOD is contributing to the usage but I'd have expected that to be covered by the new display controller and modest battery increase. And on the days when I've kept the phone face down versus face up on my desk I've only noticed a few % difference in drop off

I can’t identi anything specific that is causing my 14 Oro Max drain. I have AOD off, 5G off, and background refresh globally off. I’m a very light user, most of the time it’s sitting unused on my desk or in my pocket. I have automations set to turn on airplane mode & enable low power mode between the hours of 11;00pm and 8;30am and the battery drain when it’s in that state seems about the same as I saw on my 13 Pro Max on iOS15. It’s the drain during the day when I’m not using it that seems to be much higher. It used to be that if I really didn’t use my phone at all all day, which quite often I don’t apart from maybe 10 minutes total use for messages, I would lose about 15% to 20% battery for the whole day whereas now I lose more like 25% to 30%. Before I liked the fact that I could go away for a weekend, even a long weekend, without needing to bother with a charger (just a cable in case of emergency) but I wouldn’t want to risk that now with my latest & definitely-not-greatest 14 Pro Max.

Given what I’m seeing with inactive drain seemingly only when not in airplane mode a network reset is definitely the next thing I’ll try. Maybe it is doing something weird and power-hungry somewhere down in the network stack. And I had really hoped that the latest Qualcomm modem which is on a smaller geometry now would give an improvement there.

I agree with those findings. I've been on vacation taking a lot of pictures with sunshine. The new 2000nits max are beautiful, but taking pictures all day in the sun like that drains the battery like crazy. Which is kinda to be expected.

AOD on/off, weather widgets, all that stuff, made a minimal difference to me.

I tried today with latest beta of 16.1 on iPhone XS, I did at best 4.30h on screen time. On iOS 15.7 sure it was at least 5h.

>iphone needs days to settle after an update

This is the dumbest copypasta to the battery drain problems ever yet I always see it in every thread.. no, your phone doesn't need to "settle", whatever that means, it indexes some files which takes half an hour max, then it operates as normal. The problem is in the garbage *.0 updates that are optimized only to the latest hardware, Apple then irons it out in later versions.
That too is copypasta. If that were true then none of the others methods could fix power guzzling / hot / both iDevices.

A reset (vol. up > vol. down > pwr button hold) has fixed the majority of iDevice power guzzling for me in the past 15 years of dealing with iDevices.
If that doesn't work and it did not start with an OS update, then I toggle on Low Power mode.
 
With all the thousands of developers and thousands of the public downloading iOS 16 in beta
Nobody picked up on the battery drain??? How could that be????
Let’s see what happens with the final draft of 16.1. Apple support said ‘they are aware of the issue”

I was using 16 since the first public beta and never reported the battery issues because I assumed it would be fixed by release

So hopefully this helps someone else out as I appear to have resolved my battery drain issues. I did two things and am not sure which is responsible for my improved battery life. So I turned Siri on then off again, I'd seen it recommended in the thread so gave it a shot. Then, and this one is more speculative but I was using 'blur background wallpaper' on the homescreen so I turned it all off and replaced with a solid color. Things are looking much better now, I finished the day yesterday with 32% battery after an 18 hour day.
