I’m not much help because the 12 pro for me is working great. However I’ve been in your situation before with previous iPhones. We buy apple because it supposed to just work. You paid a good price for your phone I’m sure and luckily have the best customer service around. Just call up for a swap to battery replacement. They might make you do a restore which I wouldn’t be surprised if it’s software given it’s software that caused it and you “used to” get good battery life.

I’m running the latest iOS 15 beta 3 and the battery life is terrible. iPhone 12, three weeks old.
same here. battery capacity dropped from 100 to 96% since the last 14.X beta until now (15 b3).

Agreed. I turned it off briefly because beta Private Relay was wonky. Then forgot to turn FF back on. Besides all the adds, I noticed the phone was exceptionally slow and jittery until I turned FF back on.

I have been getting this problem (sudden excessive battery usage) twice with my SE2020 over the period of a year and a half.
Every time a network setting reset has immediately solved the problem.
I have no idea why this is happening, but I can only imagine that in certain circumstances something goes wrong with the network to the extent that a full reset is required.
The only downside is that you will need to reconnect to your wifi.

I want to downgrade to 13.7 but I cannot find a way.
Since I"ve upgraded to 14 My iPad will not connect by wifi to my digital qsc mixer.
Really disappointed. I bought a new iPad and its the same thing, I will be returning it.
But how do you know it’s working
Swipe up from the bottom of the screen keeping your finger on the glass for a couple of seconds. You’ll see all of the active app windows in a series. Swipe each window up to clear / exit the app.
This is DEFINITELY a software bug. While the reset / restore seemed to help, the percentage is all over the place. Phone said 97%. Restarted it, says 100%.
My understanding is even if you wipe the device, you can’t install an
iOS that earlier than the one installed before the wipe.
In other words, there’s no “factory wipe” option; only erase and restore.

How are you sure that this is coming from Apple? I mean, normally after a software update a bunch of apps are also updated. Everything that runs on the phone can affect battery life, not only Apple stuff. I’m kinda happy with my 12 mini battery life. I’m light user and I always have limited number of apps, but I haven’t noticed any degradation through the upgrades…
When you have a severe battery drain following when nothing else has changed, the likely culprit is the iOS software update.

Exactly. It's a fairly simple process of elimination. We've seen this way, way too many times for it to be anything other than issues coming directly from Apple. Most of us are savvy enough to quit our other apps and make sure they aren't able to eat up battery with background updates (check settings). This happens over and over and over again to countless users. Something is going wrong during Apple's iOS updates (even minor updates) causing one of two issues. 1) Battery life is immediately and sometimes dramatically reduced. Although a full wipe and reinstall can fix this, I've also seen this battery life issue persist even if you do a full wipe and reinstall. 2) Battery life is not actually reduced (or not by much), but the battery indicator no longer accurately represents the actual remaining battery life and the rest of the iPhone battery monitoring software likewise 'believes' the battery is draining much faster than it actually is. This too may, or may not, be fixed by a full wipe and reinstall. (My own current iPhone SE now has one of these magical batteries that drains from 100% to under 20% in about 45 minutes, then drops to 1%, and then last basically forever at "1%" - nothing I can do has fixed this interesting bug introduced immediately upon upgrading to iOS 14.)
As a guess what's going on here is that Apple's battery calibration is getting mucked-with basically every time they update iOS, and sometimes it screws something up so badly that even a complete wipe and reinstall can't fix the issue. Even if an update only borks one in ten thousand iPhones that's still a lot of iPhones borked each update.
I was recently fooled believing iOS was causing a major battery drain problem. Turns out an app update (Reddit) was the cause, and there are loads of complaints over at r/Redditmobile. Most of us moved to a 3rd party app (Apollo). Not always the easiest thing to find - I noticed the phone heating up, but sometimes you need to toggle the battery usage (% vs time) for it to jump out.
FWIW, I don’t update every version, but my XR has seen a few from 12/13/14 and other than the odd short-term ‘indexing’ drain, I haven’t noticed any impacting my battery life. After 23mo.(96% health), I think I can still get very close to Apple’s ‘15hr internet’ SOT although I typically cycle ~7hrs/50%-batt daily using a ‘custom optimization.’
Crazy how the same phone with 91% battery health on iOS 14.2 lasts longer throughout the day with same use as one with 100% battery life running iOS 14.7.
Apps are definitely a cause of concern. However, when you download an update with no other changes and your battery is at 80% when it was at 92%, all fingers point to the iOS update.I was recently fooled believing iOS was causing a major battery drain problem.

A few releases ago FaceBook was causing battery drain. It can always be apps that don't completely follow app requirements but work ok until an update in the OS
Update. 2 hours and battery at 75% just from using Safari. 5G is off. Firefox Focus is running too.
Unbelievable. What a crock.

11 Pro Max user here and I concur. Noticed when recently updated to 14.6 and 14.7 and shortly after I was almost out of battery by 8pm. Unheard of previously.
It’s not consistent, but it has been noticeable on multiple days.
I tried restoring my phone to the last backup I had which was in Feb 2021 sadly.
(Must do more often). The back up worked but the iOS version remained at 14.7 !?!? So it only backs up your apps and data, not the iOS version. Not fixed either.
A reset to factory settings also didn’t get rid of 14.7 either. Still not fixed !
Yeah. It sucks. Another iOS update , more battery woes…. And now this phone’s camera has started freezing when you open the camera app. Then it unfreezes shortly , then freezes again. Repeatedly ! So the camera is now useless. Have redone the wipes and restores and it’s still doing it so suspect hardware , not iOS related as it’s also doing it in other camera apps. Anyways , I can’t get rid of 14.7 to verify either way and have wasted ages trying to resolve.
It’s got apple care so will be taking it in for them to sort out.

Out of curiosity - those saying they have battery issues, I see a few saying they have erased and restored the device. But don't recall seeing performing a "hard reset" that doesn't erase anything, just restarts the OS. I'm talking about the process of pressing vol-up, vol-down, hold power button until you see the apple appear.

Actually - if you have auto update enabled for apps, when you do an iOS update, apps may update immediately after. I've noticed that on iPhone and Mac OS'. Or - an app could update, but some functionality lays dormant waiting for the new OS. Once it's available, becomes enabled. Many things can happen at and around the time of any OS update. This doesn't eliminate the fact that an OS update can cause problems as many of you are experiencing. It's just interesting to me how some do, some don't, and many have the same hardware.
Another update. Not sure whether to laugh or laugh.
5 days in on 14.7.1 and my battery has been at 100% for the last two hours. 😂
