iPhone 12 Pro Overheating

I’m experiencing the same issue on my 12pro. I do have the clear Apple branded case on the phone. Does not get hot while charging. But when surfing the net, or flipping thru Facebook it gets pretty warm. None of that is on 5G either. Also battery drain is FAST. Woke up at 6:45 with 100% charge. Been reading the news, it is now down to 84% in only 34 minutes.

I'm using the Magsafe charger with the Magsafe clear charging case. I've not felt the phone get hot while on the charger OR when plugged in. It does get awfully warm though when I'm playing a game (backgammon) or just looking at Facebook for longer than 6 or 7 minutes. Seems like yesterday the battery was going down really fast. Not so much today. Odd?

Been doing a few tests the past few days and it seems that my iPhone X with 80% max capacity battery is losing a little bit more battery than the new 12 pro but at the same rate almost.

this morning an hour in after I woke up playing with both phones same apps at the same time now I’m with 92% on my 12 pro and 91% with my 10 (remind you, it’s 80% max capacity)

losing almost 10% an hour on a new phone without using any videos by the way, this is ridiculous.

Suspect Photos / temporary restore issue.

Just come from 11Pro (through all the OS betas) with no issue.

New 12Pro is getting very hot under moderate use (Twitter etc)

Apparent from battery drain that the Photos re-analysis is running. Suggest check that and wait for that to finish*

*mine takes a few days on a new phone (65k photos?). IIRC the facial/object recognition etc is done on device and kept on device for privacy. Thus, when you upgrade/reinstall the restored backup doesn’t contain the search index for your photos and your new phone spends a few days caning the Core/GPU to analyse all your photos.

I assume that’s maintaining a baseline load that leads to hot running when you do more on top.

Hello, I've had the same issue I'm not doing anything major, I was recording a video for top 3 minutes and the back was extremely hot. I cooled down after I stopped doing any activity. I don’t use a normal charger that I had from my previous iPhone. I have the iPhone 12pro.

Ive never had this issue with my older iPhone 8plus, would this problem go away? It is very uncomfortable and scary.

I had the same issue. Contacted Apple support , they ran diagnostics and found everything in order. They recommended to update to 14.2 which I did. Then I switched it off for about 5 minutes. So far so good , it has been around 2 days now. Will continue to observe and see how things work out.

try this out and see what happens

Hi, I’m facing the same issue with my iphone12.

usually I remember with my old iPhone 8, I only had these problems from time to time when I was charging my phone and using it at the same time. Like while watching videos or playing games etc. However, at the moment without charging only by using some apps I feel that it’s a bit overheated. No idea what to do. Just brought it 10 days ago🤨🤨

I just restored my iphone with no apps and no data. Yes still I can feel heat. Yes I have a sizeable photo library but I didnt faced this issue with any of my old iphones and my last one is XS 64GB. How photo library will be a problem? If so who need to fix it? do I need to delete my photos? :)

I’m no expert but - in my case my photos background task is done and my phone is no longer getting hot under load.

FWIW I’ve had every new phone for a while and for as long as I can remember they’ve caned the battery & got hot in their first few days. 99% sure it’s just background hard work.

Heat diffusion on the 12 is just maybe a bit different with different materials / form factor.

I've tried to stay out of this the sky is falling thread, but you are actually quite correct. When moving data over from one phone to a new phone, especially if there is a LOT of data, such as photos in the multiple thousands, it takes a lot of indexing to move the data and that causes the battery to work hard for what can be a few days depending on the amount of data.

Just got my iPhone 12 pro last wk. & started using it for the last 5 days....Just noticed it overheating today after using it continuously for 50 mins.Had to turn the power off to play safe.Don’t think this is normal & was thinking of returning it & have it replaced or just return it period.I know this problem occurred on my previous old iPhones but why is it happening to this new & expensive phone.

It will shut itself down if it truly overheats.

There is no need to "play it safe."

Heating is not a sign there is anything wrong, it is a sign the CPU is doing a lot of work, and many web pages require a huge amount of processor and graphics work.

It doesn’t need anything open. Only real way to tell is to keep an eye on battery consumption. It’s background tasks (particularly AI use within Photos) that works the CPU hard in the first days after install.
