I am seeing reports everywhere about the phone getting hot under various circumstances, mine is during phone calls, happens quickly most heat felt in same place as everyone else, near the volume up and down and action button, but whole phone gets hot, and I do mean HOT, and it burns through battery life rapidly.
Is anyone else getting heat under this circumstance and have you found a solution, not sure why the processor would work so hard during a phone call.

Apple must have noticed these heat issues during product testing. Very disappointing.
 
And as note, I am day 3 after restoring sat morning, and agreed they must have known internally there is an issue here. But the phone call problem for me is a big one, firstly the heat, second I estimate it could only go 90 min on a full charge due to how hard it is hitting the cpu, why I cannot imagine

I just had this happen to me during a phone call on my 15 pro. I was actually going to decide between the pro and the pro max by the end of the week, but today during a phone call the phone lost 15-20% on a 20 min phone call. Other than that, all day w some phone calls I don’t recall overhearing, and no overheating as I used the phone normally browsing. So this was worrisome. When I went to see what program took up the most battery, it says “home and Lock Screen” in that timeframe. Now I can’t close this so I’m not sure, maybe a widget going crazy?

My wife's 15PM is like a camp fire at times on extended phone calls, and her battery life is terrible. This morning she charged to 100% and when she got home from work (10 hours later) is was at 42% battery life, she said normal use through out the day.

Not expectable Apple:mad:

Interesting regarding the widgets, I do not have any interactive widgets or any widgets that differ from my iOS 16 setup, but may try removing them to see if phone calls can be made while we wait for Apple to resolve this mess.

I just looked and sure enough, home and Lock Screen soaked up 68% of my battery, I think you are onto something here. Says wallpaper, you know what I bet this is, I bet it is that new IOS17 feature where you can create your phone wallpapers or contact "posters", which are clearly the same code as the wallpapers from iOS 16, running a process and causing the heat and battery drain during a call.

Yes I can totally relate to that. Are you coming from a back up or did you set up your device as new? The problem is only when making cellular phone calls(WiFi calling does not cause the phone to drain battery nor it gets hot). At least that has being my experience. Here’s an update, I follow apples phone support advice and erased my phone to factory settings. Didn’t even put my iCloud while setting it up. As soon as it was ready, went ahead and made a 45 mins phone call(cellular) and only drop like 5% of battery and the phone was cold to the touch. Then went ahead and and restore the phone from a back up. After it was done, went ahead & made cellular phone call and the problem was back. Lost 17% of battery in 20 mins into the phone call and the phone was burning hot. Then I let seat for a while till it was cool. Turn on WiFi calling and place a phone call. The phone was cold and the battery was behaving normal. Only lost 2% in the 35 mins call. Today am gonna erase the phone and do a phone to phone transfer as oppose to the over the air back up. Will update on it. But so far this tells that is not a hardware issue, rather a coding problem within iOS 17 and how it handles cellular phone calls when coming from a back up. I now it sounds weird but anything in software is possible. Let me just clarify that browsing the web, being on social media and doing anything else on cellular does not causes the phone to heat up nor to deplete the battery abnormally. It just making phone calls either normal phone calls or FaceTime audio phone through cellular that triggers the problem. Haven’t experienced the overheating issue while charging it, wirelessly via MagSafe duo.
 
I restored a backup. Mine got hot on a WiFi call as well, that was the first test I tried.

I'm having the same issue with my Pro, shared on the other threads too. But this is an interesting point about the posters... I haven't used iOS since my iPhone 5 (iOS 7 or 8 maybe?) so I haven't done much, but I have added posters to change the background color since I'm not a fan of the grey!

Yep the blank grey space is very boring, I removed the poster, still heats up, I think it’s related though, just buggy code I suppose. Considering an erase set up as new, as o need to be able to make calls

so the only fix we know is an erase and set up as new, I would at least need to sign into iCloud (non restore) can anyone confirm if a new setup with iCloud signed in works to resolve the phone getting hot and draining battery during a call?
 
I have experienced the same issue today after couple of days having overheating and battery drains in more random scenarios due to couple of apps, which I thought was because of the lack of optimisation.

Today I had a 5 min FaceTime call, and my 15 Pro Max started to overheat quite a lot and caused my camera to lag in an unusable way.

Another interesting thing is that now the battery percentage usage of Home & Lock Screen is 45% and I just have the new wallpaper of the iPhone 15s. Nothing dramatic.

I hope that it is not a physical issue but I haven't tried restoring the phone yet.

iPhone 15 Pro 256 GB, same issue. Phone got really got during a 6 min phone call, 2 bars of reception today. Battery drained almost 10%. Genius bar appointment is set for Sunday but I don't really have any hope.

Had a one hour call today and my Pro Max barely got warm, had a 30 min one yesterday and it was the same then.

Haven’t had any battery drain or the phone getting hot, sure it will get a bit warm when doing a lot like installing 40 app updates or something but not enough to be uncomfortable or really noticeable unless I look for it.

Same issue, but inconsistent. I've restarted and it disappears and then reoccurs. I'm thinking it's a software bug that gets triggered by another app
 
I did the iPhone to iPhone transfer including my eSIM. I make a daily hour long call and my iPhone stays cool. The iPhone 15 is the first iPhone to use 5G voice (VoNR) I did toggle that feature on (it was defaulted off) .my .02 cents
 
I also have a 15PM. During the first day (on Monday) while indexing it did get warm, not to the touch where it was uncomfortable but it definitely produced a good amount of heat.

Today, I recorded a few videos and both 1080P and 4k, played 5 games of call of duty, played some Diablo, browsed social media for another 10 min and then had a 52min phone call. Phone didn’t warm up at all during the video recording, web browsing social media browsing. Warned up slightly during call of duty. Warmed up a little more during Diablo (not anything uncomfortable) and didn’t warm up at all during the phone call. I even did a FaceTime call which lasted about 10 min. The phone warmed up slightly but once again nothing crazy. No insane drop in battery life either. The phone call began with 62% battery life and by the end of the 52 min call it was 60%.

While I dont doubt that there is overheating issues occurring out there I’d love to know what Apple officially has to say about it. It seems like people are experiencing overheating issues during different scenarios from one another.

Also (not sure if it makes a difference) the phone call was over cellular, I ensured WiFi was turned off + I’ve always kept 5G turned off to preserve battery life since my 14Pro. Curious to see if those who are having hot phones during calls are making calls over 5G
 
Just curious, those are experiencing this, are you using WiFi calling or cellular? If you are using cellular, do you have 5G (Auto or On) 5G Standalone or Voice Over 5G Standalone set to On and (Allow More Data on 5G or Standard for Data Mode). How many bars of signal? Under Settings>Cellular, do you also have iCloud Drive and iCloud Backup set to On?

5G auto for me. Was able to replicate on 2-5 bars of signal. Both iCloud options are on.

Today, I did a test call with my wife. On a 35 minute call, my battery percentage dropped 22%.
 
Did another call this time 5G set to on, full bars. 10 min phone call over 5G resulted in 1% battery loss and phone is not warm at all.
 
An update on my issue - My specific problem was not overheating on video, charging, or other use cases, Only on phone calls, and it was persistent on Wifi, 5G, LTE .... any voice call. Last night I reset the network settings from the reset menu and then a restart. At least as of this AM, it seems to have resolved the issue. I've had a few test calls to my office landline of 15 minutes without any noticeable heat issue. We'll see if it reappears, as I previously thought a restart had resolved it.

For those with the issue on voice calls, try the reset. I'm on a 15P with AT&T
