iPhone 12 Pro Overheating

I now possibly have a solution - it’s as simple as updating the software from version 14.2 to 14.3! Let’s see if it helps!

I just had e very good call with Apple Support. They rang me at the agreed time and listened to me describing the overheating and other problems that I’ve exoerienced with my new device (iPhone 12 Pro) . We ran hardware diagnostics together and everything seems to be in order on that front.

The problems may be due to my device running on Software Version 14.2. The advice was to update it to version 14.3 (which I didn’t know already existed, as the device is new and came with v. 14.2). Updating to v. 14.3 should apparently fix all of the problems I’ve encountered.

Apparently there’s something wrong with software version 14.2 which makes the device work too hard to try solve the problems and as a result it uses too much energy, leading to overheating, using up too much battery life, and shutting down functions - like dimming the screen, and dusabling the torch and canera flash - as it’s trying to deal with the overheating. It may also lead to crashing and restarting (which I had plenty of in the first few days) Apps (like FB which may cause more heating) may crash too. The display should present a warning (thermometer image and warning text) about the overheating , but it may not do this in all cases - I never saw the warning on the screen (which again may be a software issue).

If the problems still persist after the software update, I now have a case number and through that a way to get a new phone appointment and/or Apple Store appointment to continue researching the issues.

Let’s hope the software update will fix the issues! 🤞 I feel hopeful now. Hope it works for you guys as well!

Actually, i have found a solution - tough partial and applies only to those in similar circumstances. I had, as part of my Norton subscription, downloaded on my iPhone 12ProMax the app and activated, as it suggested,the VPN. Well, my phone started with the overheating and battery drainage issues, even consuming up to 65% battery by 10 AM!!!

Once I removed the VPNs, all went back to normal. no overheating, and now it is 5 pm and i still have 70% battery despite normal use of the phone (calls, texts, internet searches, etc)

So I hope this helps someone

BesT of luck

But only using one app for less than 15 minutes (e.g. reading the news) and the device overheating to the point that it’s too hot to touch is not normal. I have been told borh by the reaeller and Apple Support that this device needs to be repaired. I suggest everyone who experience inreasonable overheating woth their iPhone 12 Pro return it to be repaired or replaced. This is surely a manufacturing error, something’s wrong with a batch of devices.

Hi everybody experiencing overheating issues with their new iPhone 12 (Pro/ Pro Max)!

I have a new tip from Apple Support that might help:

If you've backe-up and then restored your old iPhone to the new iPhone 12, you might have transferred some old apps that are not compatible with the new operating system. Make sure you've made a new iCloud backup (or laptop backup) and updated your iPhone 12 to Operating System 14.4 and then remove most of your old apps from your device. Apps that are used frequently such as WhatsApp and Facebook etc. may have been updated to be compatible, but some more rare apps might have problems with interoperability and cause software issues and thus overheating. Note that you need to restart your iPhone after removing the apps (otherwise they wont be completely cleared). Then get the apps you need anew from AppStore and thus you'll get the updated versions of them, which should hopefully function better and not cause issues.

My iPhone 12 Pro was sent to the Apple Service Center to be repaired, but there is apparently nothing wrong with the hardware.

It was returned to me and I have since received this advice to remove old apps. I am now testing if it will help with the overheating issue.

Today Apple sent me a message on this forum to Their support page.

after filling in a few questions they phoned me, ran a test on the phone and said they had quite a few people reporting the same issue.

They have recommended updates to 14.3 And given me a phone number and reference to ring if i have any more problems over heating.

Hopefully it will be ok,

But will i ever be able to trust this phone won’t catch fire and burn my house and family.

I now have to have it in my pocket all the time, charge it in daytime so i can keep a eye on it,I also have to take it upstairs each night and place it on a tile in the bedroom just incase it catches fire.

Fingers crossed it will be ok.

I’ve been having the overheating issue since I got my 12 pro max and finally solved it. The phone would always be warm, even more so when I was actually using it but nothing showed up in the battery history significant. I restored a few times and reset all setting but after a lot of digging I discovered a bit with I cloud, particularly I cloud for windows creating a sort of never ending sync, so I turned off iCloud for safari, deleted the local bookmarks, uninstalled iCloud for windows and then turned iCloud for safari back on and no more hot phone, works for me, so hopefully it may help some of you.

I can confirm that on my 12 pro max the overheating issue was due to 5G network. I have notice the problem while playing CODM when the phone was litteraly burning , other apps worked just fine on 5G. On 4G or WiFi the phone was just warm on CODM. Backround app refresh off, iCloud backup for the game off. No heating while fast charging 18/20W.

Hi I got a new iPhone 12 Pro on Jan 16, 2021.

Problems:

1) PHONE GETS HOT WHEN SETTING UP - My phone also got very hot to the touch during set up. I was told by the Apple representative who was guiding me on the phone that this was normal. (I remained suspicious cause it was TOO HOT.)

2) PHONE GETS HOT WHEN ON FACEBOOK - My phone would get hot when I watched some videos on Facebook ... so HOT that I would feel the burn on my hands even one hour later. When I stop using the phone, the phone would cool down.

3) DROPPED CALLS - Then I noticed when people call me ... I would answer by pressing the green button, but I couldn't hear the caller (whether on speaker or not) and the caller couldn't hear me, yet it would show the call is connected. Then a few seconds after being connected, the call would just drop. Then I had to call the caller back and we would be connected. This happened for all callers who called me.

4) HOT PHONE SOMETIMES WHEN CHARGING - Sometimes the phone would get hot when charging, sometimes not

5) AREA ON THE PHONE WHERE IT WOULD GET HOT - Back of phone ... A) top corner opposite the camera B) mid section of the back of the phone.

SOLUTION

1) I phoned Apple and the representative did some diagnostics ... battery health was ok she said. Then she did another diagnostic and asked to go to General > Reset > and click on "Reset Network Settings". After doing this, I could receive and hear the callers (on speaker or not) as normal.

2) After doing the "Reset Network Settings", I then went back to watch the Facebook videos that made my phone SUPER HOT (gets super hot by 1 min and 50 seconds of watching the video before doing resetting) ... and luckily after the resetting, the phone remained cool (well it was slightly warm as would be expected from a working machine) ... but at least it didn't get super hot. I watched the videos 20 plus times just to make sure, and yes, the phone didn't get hot.

3) When I charge my phone, it was no longer getting hot ... it remained somewhat cool ... at least the times that I checked.

NEW PROBLEM

1) So when I am speaking on the phone AND someone texts me or sends me a photo via text ... then boom ... the phone gets hot again ... but the heat is in the mid section of the phone, not so much heat in the top corner opposite the camera. Again this heat makes me feel like I'm holding a hot plate, causing a very UNPLEASANT sensation on my hand ... and then the battery seems to drain very quickly.

I am not sure what the solution is to the NEW problem. What I have done the 3 to 4 times in which this has happened in the since Jan 21 (it is Jan 28 today), I go and do the "Reset Network Settings" ... from doing this the phone seems to remain more cool and the battery doesn't seem to drain as fast (so it seems).

However, I SHOULD NOT have to go and "Reset Network Settings" all the time!!!!

SO APPLE ... I HOPE YOU FIND A SOLUTION TO THESE PROBLEMS AND TELL US HOW TO FIX THEM. We pay a considerable amount of money to use your Apple phones ... so please give us tested and quality products ... please fix the problems. I hope Apple staff reads this stuff. Thanks.

Anyway for those who have the hot phone issue ... please try "Reset Network Settings" and let me know if it works. You will have to re-enter your Wifi Password though. But all the other PW remains unaffected if you do "Resent Network Settings"

Hope this works!!!

I have just spoken to the reseller that I bought this device from and they instantly said that this is not acceptable performance from a 1300 euro device.

They adviced me to take it to their store for repairs, and if they can’t resolve the issues, it will be replaced with a new one. What a relief. I really hope it will function well after the repairs, or that I get a new one that doesn’t have these problems. Or if nothing else, there’s always the option of rescinding the purchase of a faulty device.

If your device has the overheating issue etc. - speak to your reseller. Or contact Apple Support if you bought it directly from Apple.

It should be repaired or replaced.

I again had random surge of heating quickly and change settings with no result. Like turn off 5G. Dynamic charging but no chance. I did remember back in beta on my iphone 7 that heating was issue when I used widget the new hot feature.

Thinking new 12 serries this might not be issue. I removed all widget of my screen I do like them a lot but worth to try see if they still causes problem.

after I removed then all phone heat went down felt it with touch and screen poped slowly back to normal brightness. Still running same apps as when heat start.

I gues there still issue in widget system went under the radar? Maybe others can confirm same result?

Hay,

i can share my experience on my 12 pro. I got a new 12 pro and I transferred all my data from 7+, used for 4 and half years. Then two days later I got a screen frozen issue and apps not working, phone getting hot, but not the phone shutting down. Apple support couldn’t solve the problem and in the end I got a new replacement phone.

I didn’t load my old data instead I just backup my photos, whatapps,notes, reminders and other apps that needed backup.

For those App I don’t need history of data and backup I downloaded from App Stores.

I turned off 5 G cos my area has no

5 g signal and other unnecessary locations services.

My 12 pro much better. I don’t face a screen frozen issue or phone getting super hot while I m using Apps and browsers concurrently.

But there are still issues that when I open a certain app, my local bank app, the phone quickly getting hot and App Not able to download from the App Store unless I restart it.

I have a fix for you if it feels too hot for you liking go to settings; go to cellular; go to cellular data options; then voice and data I recommend putting LTE as it will keep your phone at a normal temperature as in the older versions now with 5G on or auto the phone burns battery faster thus making it over heat. I would also recommend going to data mode and putting in LTE never leave your phone on 5G for too long.

I hope that works for some folks. However, that hasn't helped in my situation. The only thing that consistently works is low power mode. Yesterday I kept it on normal mode and it was fine all day, this morning 30 min after pulling it off the charger it started getting hot and the screen went dim. No different apps, no different activity (just email, Facebook, a few crossword games, etc.)

Before having my phone replaced, I reset it and didn't restore a backup. I ran it with just email and the Apple apps for a couple of days. It still got hot so Apple replaced it.

Thanks, I actually just did speak with Apple Support again. I will now try what they adviced:

1) backup the device on my Apple computer

2) restore it to factory settings

3) set ut up as new once again

4) test use it for a few hours to see if problems still persist

5) if it still overheats etc. contact Apple Support again and then have it taken for repair (it’s under warranty) or replacement

Hope this helps others who are experiencing the same issue.

I had this problem with MagSafe, ended up replacing an iPhone 12, MagSafe and a case. I got told by apple that the coils/magnets were not outputting the right watts for charging, because I was not getting anything above 4watts using a 20w brick.

after My second MagSafe I ended up returning it. Surprisingly enough got the MagSafe duo and that’s been working fine for me, my second iPhone 12 replacement unit has not heated at all on me ever since I had that incident back in November were it shut down after frequent usage.

right now the MagSafe duo and the iPhone 12 work normally but it took a lot of long sessions with apple to figure it out.

they don’t read these sections by the way, these are more of a collective solution from users to apple problems...
