iPhone 12 Pro Overheating

Mine delivered a few days ago is overheating whilst recharging

Then you are saying your phone is displaying the Temperature Warning while charging? If that is the case, then you should take it to Apple for evaluation. If it is not, your phone is NOT overheating. It is doing what batteries do when being charged and that is get warm. Depending on whether you are fast charging or using a slow charge will also directly influence how warm it gets. If you use a 20W charger, it will get warmer. If you use 5W or 7.5W it will be less warm.

People on this thread are being scared about something which is normal. Especially with brand new phones. Over the first couple days, when a phone is set up from a backup, it takes hours to days to index all the data. That process causes heat as the battery and processor is working hard during that period.

I also see people saying they set up their phone and immediately start watching videos or playing graphic intensive games. This on top of the phone indexing the data will cause the battery to get very warm.

I've been in touch with apple support who were very helpful. A new software update was applied on Thursday and the problem has gone away. I am now using software version 14.2.

As far as the comment above about it taking hours or days to index data and this is a cause for the overheating. Not sure I agree with that, I would suggest there is something wrong with the indexing code if that were the case.

Anyhow 14.2 appears to have fixed the issue, all my data is there and the phone runs as it should and feels cold to the touch.

That's OK.......You don't have to agree with me. But it is fact that lot's of data requires all the data to re-index to a new device. if someone for example has thousands and thousands of photos, it can take hours to a couple days for all that data to be properly indexed. And that requires the battery to be used a lot. It's been this way since the beginning of iPhone and iOS. But it doesn't matter to me if you agree or not.

Back to the OP - even my iPhone 11 Pro Max and other iPhones have overheating issues on iOS 14.

I'd give it a couple of weeks - or more - and monitor battery usage before crying foul.

(or return it and wait for a new one)

I just purchased my iPhone 12 pro max, set up done , iCloud done all done . It heats up at the right hand top side of the phone ‘s back side .

very unusual heating . If camera is on then it heats up more . I just scheduled a calm with apple care , if this is really an issue with iPhone 12 , they fix it ASAP through software update or give me a good phone . If this issue is like the Canon r5 heating which is a failure then . IPhone should take back and give me a new phone .

I had my Iphone 12 pro for a week now. It gets really hot to hold while using or touching. I find that if the settings is on 5G it heats up the whole time. I find myself changing the cellular service to standard and it does not get hot at all. Maybe it's the 5G.

Hi, I visited this forum for the exact same reason as the problem posted a couple of days ago because my iPhone 12 was overheating and the battery was draining at the same speed as my iPhone 8 which was 2 years old. Turns out it was due to the new phone not being updated to the latest iOS version, my phone was brand new and I assumed it would automatically have the latest operating system installed, it didn't. Update your phone to the latest iOS as it fixes some major battery issues and also go to mobile data setting and (if you don't need it) switch off the option for you phone to search for 5G. Even without a 5G contract the phone will still search for 5G internet and this drains the battery an insane amount. Since updating my phone and switching off 5G my battery has been perfect, barely dropping even with heavy use. Hope this helps.

I just got the 12 Pro Max and already noticed it’s overheating when I use it. It’s very hot to the touch on the back. I had the Xs Max previously and I never felt it get hot.

i hope there’s a fix to this. Apps are glitching and my network actually seems slower. Uploads are taking forever. Wth!!!

Unless it shuts down and tells you it needs to cool, it's not "overheating."

Depending upon the applications running it's normal for the phone to become warm or even hot in normal use; the internal temperature sensors will shut it down if it gets too hot.

The same is true for heating during charging, especially fast charging.

I read another post that said something about not having the latest update. I figured this phone would be up to date since it’s new but it wasn’t. I went ahead and updated to iOS 14.2

havent noticed any of the screen issues since but still definitely a really hot phone.

ill keep on eye on things and contact Apple support if necessary.

I have been having the same issues! I just got my new 12 pro yesterday and have already been noticing the overheating and the battery life is not as good as they usually are when they first come out. My sister who also got a 12 pro a week ago is having similar issues. Mine was overheating today when it was plugged into CarPlay, while I was on snapchat, instagram, Facebook etc. Like you said, it's minimal usage that is causing the overheating. I'm just waiting for them to send a recall and a new phone lol. Hopefully this gets resolved quickly because mine heats up in a matter of minutes to where it is very noticeable and almost alarming. Mine doesn't even get hot when it's charging so I don't know what the issue could be.

It is overheating, as in the iPhone shuts down because of a “temperature” screen telling you the phone is shutting down because of overheating!!!!

Which is exactly what I said:

Got my iphone 12 pro max yesterday, everything went smooth with a bit of heat during downloading apps which is ok! Today i turned on youtube on the phone to watch on my smart tv! After half an hour and while the phone screen was off ! The phone was really hot ! Ineas shocked ! Again i tried downloading some clips from youtube again on the phone and it got too hot again !

I’m on my third day with the 12 Pro Max and outside of wireless charging using Apple’s MagSafe charger, noticed no excess heat... until today. It’s not on a charger, just playing streaming video over wifi and it’s definitely quite warm. I wouldn’t call this overheating but it’s definitely noticeable when I pick up the phone.

It seems the new A14 chip runs a bit warm when the phone is performing certain tasks. In my case, video streaming. What’s interesting is that I didn’t notice this until today. It may have happened when watching video yesterday but for some reason, I didn’t notice. The only real difference today is that I switched to 4G only so that I could test battery performance differences.

I just upgraded from 6s Plus to 12 Pro Max and I am also noticing my phone is heating up quickly while doing normal tasks. I am not concerned at this point but I wanted to chime in to let others know it may not be unusual while it’s new.
