iPhone Overheating is Getting Ridiculous

The only feature that you could turn off that is extraneous and causing your iPhone to heat up (it is not overheating) would be the WiFi/Cellular Data connection. Because FaceTime uses streaming video/audio it is going to use more processing power with just that. There are no other items running that you could have custom options to turn off that would help. But what will really tax the entire phone is if you have a relatively weak WiFi or Cell Data connection which will strain everything. So hang up if you have a weak connection and it will rapidly cool.

If you are NOT seeing a message your iPhone is too hot and needs to cool down, it is NOT overheating. iPhone has built in temperature management to protect from actual overheating situations. It may get warm, which depending on use scenario can and often is quite normal.

That said, my iPhone 14 Pro and 14 Pro Max are not exhibiting any extra heating in normal use. If your is, since this is a user to user only forum and no one here can diagnose or fix anything which may be causing this on your phone, it would be wise to schedule a time at the Apple Store Genius Bar and let Apple run diagnostics on your phone.

OK......I don't know what it is you're expecting from a user to user only forum? No one from Apple is here. We can't diagnose your phone if there is an issue with it even if we wanted to.

No one is accusing you of anything, certainly not ignorance. I can tell you I have absolutely NO unusual heating issues on iPhone 14 Pro or 14 Pro Max at all. Hence why I recommend you schedule an appointment at your Apple Store Genius Bar for evaluation. Debating us won't get you much of anything here.

If you are in LA this is a huge problem for you not only weak signals due to interference or distance from a repeater (no on in LA wants one in their backyard) but also from the vast number of people connecting to the tower. And if you are near LAX, Burbank, or Van Nuys airport it is even worse (I'm near DFW airport). Using 5G will also heat up your iPhone rapidly and just add to the issue.

I personally have never had an issue with any of my iPhones overheating or feeling uncomfortable to touch EXCEPT once but that was an environment issue (high school football mom at a midday game at a stadium with no shade with temps in the high 90s in the South and using the camera to capture video and pics of my son in action. Warning of course popped up and couldn’t use the phone until it got back to a safe temp). Since you mentioned being able to selectively turn off unnecessary features I assume you have some features in mind that you would like to control (are these features you can’t turn off or are they ones you’re not sure where to locate in settings?). Have you suggested them to Apple via the feedback form? Of course there’s no guarantee the changes will come but that would be the first step to hoping Apple listens. If every iPhone you have ever had since the 5c has had the same issue and you don’t think you are doing anything intensive (although, using FaceTime would likely count as intensive depending on if you’re using cellular data or Wi-Fi, the signal, etc) then it makes me wonder if other factors aren’t coming into play. I’m not sure how strip naked FaceTime can become unless it only allows the lowest possible resolution (which most would hate), can only be used on Wi-Fi….maybe removing the option to do Group FaceTime’s…getting rid of automatic prominence (although you can turn that off in settings if you do in fact ever use Group FaceTime). At the end of the day…it doesn’t matter if you use an iPhone or any other smartphone…if you are using a video chat feature in the same situations you are having issues with your iPhone now….chances are you will have the same issues with the device getting too hot for your comfort.

All that being said….if you are repeatedly getting the warning message that your iPhone is too hot and needs to cool off (not sure if that’s actually happening for you. I know you said it’s uncomfortable to your touch but I’m not sure if you are actually experiencing where the phone has determined it’s too hot to operate temporarily) then of course you know to have Apple inspect it and replace if necessary. If you feel like it’s an Apple only problem and you have been sticking it out since the 5c….it may be time to decide if Apple is still for you if you don’t think Apple is doing anything to address what you may see as a major flaw. Or…if you think you can invent a cooling case that will help issues while being appealing to users you might have found your goldmine

Unfortunately part of the miscommunication is due to your probably not reading the terms of use. This forum is not designed to be a form of conversation, it is a user-to-user technical support site operated by Apple. If you are indeed getting the thermal shutdown I would make a Genius Bar appointment and get your phone looked at. If you are at a certain location where you were getting a poor signal when it happened I would report that to you cell service provider.

Not actually, the resolution would have a negligible effect with the OLED screen, and I don't know what a simpler FaceTime would be. The other options in FaceTime, i.e. file sharing, etc. are not in play unless you actually use them.

You are attributing incorrectly.
