iPhone 12 Pro Overheating

I have an update to my earlier post. The iPhone 12 Pro definitely ran hot in the first 24 hours. After some research, I disabled background refresh for the majority of apps. My old iphone XR had 100% apps on background refresh without overheating issues.

In any case, after 24 hours, phone no longer runs hot. Not sure whether because it was done updating, backing up, transferring data, or because I fiddled with the background refresh.

It’s been 1 week and 12 hours since my purchase of 2 new iPhone 12 pro Max’s. My wife hasn’t really had the phone become too hot in her mixed usage but with mine? Buddy, let me tell you, this phone becomes almost unbearable to hold its soo hot! Never had an iPhone, I’ve had 8, become this hot with random mixed usage! Nothing too strenuous as far as activity goes on my end, and I keep my background processes to a bare minimum. Funny thing is, it over heated last while just LOOKING at Verizon’s 5Guw map, not even ON 5G lmao.

There is absolutely an issue either software or hardware causing this issue. This issue occurred on iOS 14.2 and now 14.2.1 as well. Not finding a correlation with any certain apps in particular as it is overheating, or heating up soo much it’s almost unbearable to hold, and I do not use any cases with my phones so they have breathing room, as the issue since it is happening while using messages, safari, chrome, spark email, USA Today, maps, and/or ESPN. Also happening with zero apps running in background.

I believe Apple should start addressing these concerns sooner rather than later IMO. There is an obvious widespread issue here again we have no idea whether software or hardware causes but the effect is there.

I just got mine last night and this morning when I grabbed my phone it was so hot I couldn’t touch it. It was not charging and everything had downloaded. I have also noticed the battery takes forever to charge and I’m not really sure about battery life as of yet. Definitely nervous about the overheating issue because I don’t want a fire to be started. That’s how hot this phone was.

that's super interesting.

I seriously wonder if there's a way to cool it down - 4K video definitely uses CPU power, but interesting where the heat is exiting (or concentrated).

I gave up on 4K-via-phone (mine is set to 1080p) -- I just picked up a GoPro HERO 8 (refurb) and HERO 9 (new) to compare (Black Friday deals - hasn't arrived yet).

I heard the transfer-to-phone is faster - my HERO 5 is bad, and HERO Session is abysmal...

Mine keeps overheating. I’m playing music. Screen turned off. All other apps **** down. Phone hot. Not ok. It also loses battery charge extremely fast and I even turned off my 5G. They need to fix this. This phone is too expensive to be having these issues.

I have also been having issues with battery life slowly draining without any thing opened. Not to mention I have my own charging pad and when I leave it for a few minutes it is extremely hot. Opening a game or even Netflix causes my phone to start getting hot.

Have you ever tried slow charging adapter 5 w for i phone 12 , its giving less heat while charging i think this is the better way of charging the new models , it may took over a 2 hrs but hopefully getting good battery helth and less heat

I got my iPhone 12 pro on 10/30. Today was the first time I had the overheating issue and it was HOT! I turned it off for a bit but it does make me nervous. I’m contacting the vendor to make record of the issue.

I purchased the iPhone 12 two weeks ago and have noticed excessive heat from the back of the device the in the last four days. Today I noticed the touch screen was starting to lag as the heat increased. I asked Siri to turn my phone off and her speech was glitching, repeating words and I finally had to force restart the phone because the speech was caught in a loop. I'm a quite concerned with how the heat may be affecting the internal components. I have been using a 20w brick with MagSafe charger every other day overnight to charge. Don't notice any heat when it comes off a charge.

I concur! I’m experiencing the same issues you’re having. My device got so hot that I was unable to launch my flashlight. I received a warning message that said, “Flash is disabled....the iPhone needs to cool down before you can use the flash”.

I purchased my phone yesterday and I must say that I am highly disappointed in the battery life. I’ve never had a battery that depleted at that rate. This is disappointing since this is such a new device. My 5G is on auto and it’s still an issue for me.

I have been having the same issue. The charging is extremely slow. I lose charge rapidly and my phone takes forever to get to 100% after being on the charger for over an hour even with the new usb-c type power adapter. It seems like this is a known issue.

I'm so disappointed by the issues of Iphone 12 since the day I bought it. It get extremely overheated and battery drains without even using a lot. Apple should recall all these devices and fix it. Using Iphone for a longer period but for the first time ever highly disappointed on my purchase.

I had a replacement ip12 pro max after 5 days of using it coz its overheating whenever im charging it. After replacement i still have same issue. So i figured out that the wall adapter i bought from apple (20W, iphone 11 wall adapter) is heating too and that's maybe causing the phone to heat up. So I bought a USB 3.0 to USB C female adapter and use my iphone 6 wall charger + lightning cable for ip12 and No heating issue happened but it took 2hrs and 40mins to full charge the phone. I now got a replacement USB C wall adapter from apple to test. Will keep you guys posted.

Went through Apple Support and they only assisted me in:

1. Turning iPhone off and turning it back on after a few minutes. Didn’t resolve the problem.
2. Backing up and the restoring the iPhone. Didn’t resolve the problem.
3. Finally got a Genius Bar appointment and they did a diagnostic while linked to their store Wi-Fi - diagnostic report showed no thermal warnings. Didn’t resolve the problem obviously.

Have to wonder where’s the problem STILL!?

I also got an iphone 12 mini couple of days and and it feels warm on the right side from the back when using it. When playing games it gets hot but managable yet annoying.

I hope they find a solution to this because this a new freaking phone!
