iPhone 15 overheating

For all this I returned my iPhone 15 pro and my decision is to wait if they are able to solve the problem without lowering the performance of the chip, but my feeling is they are going to solve the problem in the production of new batches from now on, and unfortunately the affected devices what has been produced so far will remain as it is without much option for improvement. 

I think you have a wrong understanding of software/hardware engineering. Nothing is perfect, while no app should cause hardware overheating, doesn’t mean it can’t. An OS should have a better handle of it. Hopefully Apple will improve OS based on the lessons learned.

I will assume you will agree with what I wrote “No handheld hardware device should overheat no matter what app is used or what OS it runs.

Same goes when charging a handheld device”

I suppose it depends on what your definition of "overheat" means. Getting warm is NOT overheating. Apple has very sophisticate circuitry built into iPhone which if a device is actually "overheating" it puts up a warning on the screen the phone needs to cool down before resuming use. In most cases throughout this thread, people have incorrectly used the word "overheat" as in most situations, their new iPhone was running warm or even on the hot side. That is NOT overheating. And any cell phone with a Lion battery installed when pushed hard will generate heat. If you can engineer a battery which when pushed hard can't get hot, you'll become richer beyond your imagination.

This thread was also exaggerated by people turning their new phones on, transferring data, then as most will do with a shiny new toy, put it through its paces, like recording 4k video, streaming videos, playing graphic intensive games, etc., the noticing their new phone was running hot. Depending on how much data is moved over, it can take a new iPhone a few days to fully index all the billions of bytes of data all while pushing their shiny new iPhone. Were they "overheating?" Nope. They were running very warm, which is normal and expected.

Bug or not in iOS or a faulty app are non-factors. A bug may regress in a future fix, app may not stumble on this bug but another resulting in a likewise heat issue. no hardware is to overheat when stressed on handheld devices.

That's a noble, but completely uninformed statement. Any battery when pushed hard, will generate heat. As I said before to you, when you create a battery which cannot generate heat when pushed hard, you'll win the Nobel Prize for Engineering. I look forward to you doing just that. Not understanding the science of batteries however, is not an excuse for making assumptive statements, which aren't true.

Don't bother, he/she'd be better off with a less powerful and less sophisticated smartphone in my opinion, usually Oppo and Doro and of course other makes like Nokia..etc are addressed to people that just need a phone to call and run Insta maybe couple of games

So you disagree. Thank you for finally stating that.

Now that that opinion is clear we can move forward.

You stated your opinion and so have I.

Fact remains Apple is already getting a fix out so your opinion has become mute.

Be graceful / tactful and leave it at that.

I was really hoping I would be one to not experience any of these issues, as this is my first iPhone and I was hoping to switch to the Apple ecosystem with no hiccups, but alas... thought I'd just share my experience here.

I started using my iPhone 15 Pro Max about 4 days ago. First few days went great, and no overheating at all. I also only used the phone on WiFi and charged using the USB-C cable from my old Android phone. I wasn't transferring anything from an old phone nor restoring from a backup. This is my first iPhone. I installed a few apps, and it all worked fine. Made a few video calls on Facebook Messenger, that too was all okay. Today I connected my SIM to the phone, and made a FB Messenger call over 5G, and it drained the battery super fast and got very hot. I'm not sure it was quite in the realm of what some people have been saying (cant even hold it), but it was certainly hot enough to be quite uncomfortable to hold and I was concerned about something being damaged. Furthermore, I am currently charging it using an Apple 35W dual charger, and it's also very hot then (even when I switched back to WiFi). Even after being off charge for about 10 minutes, and it was still very warm to the touch.

Just to test if it was an issue with the charger, I have plugged in my previous S22 Ultra into the same charger, which has been notoriously bad in terms of getting hot (I have the Exynos version), and even after 20 mins it's still cool to the touch. I've just put my iPhone back on charge and it's again heating up very quickly (as mentioned, I'm using the included USB-C cable with the official Apple 35W dual slot charger). The temperature is much higher than my S22U when charging, and hot enough to be uncomfortable. Also this charging was done without a case.

I should also note that the only apps I have on my phone are Facebook Messenger and a few authenticator apps. I dont have any of the commonly mentioned apps such as Instagram etc. I wonder if the issue is due to the new SIM card or higher power charger, as I had no issues before on WiFi on lower power charging.

I really hope Apple can resolve whatever the issue is without compromising or dialing back features. This is my first Apple product (and I got an Apple Watch Ultra 2), and I've heard usually great things about them, so hoping to switch over to the ecosystem...

Well if that was my iphone I'd restore it as a new phone without using any backup or d/l any app and test it, but that's me, I think you'd better call the apple support, you can also read this thread and there a quite good answer in the "Poor batter life and hot new iPhone 15 pro max" thread"

Well as I mentioned, it was working totally fine before, no heating whatsover. Its only since I added the eSIM, used it over 5G, and used a higher power charger that it's started acting up. I didn't restore from backup or anything before this. So to me it feels like its a power management / mobile data issue. But still, no harm in trying a full reset.

Try the 20W power charger, do you only have an eSIM or also a physical SIM? Is it on 5G auto or on 5G on? Because if you live in an area where the 5G is patchy and then it'll consume more battery life, and help warming up the iphone

Batteries get hot/warm when they are being charged. That's normal. It depends on the wattage charger you're using. A 5w charger, will charge an iPhone slowly and not generate much heat. A faster charger with say, 20w, will generate heat naturally.

I have an iPhone 15 pro black. Within 2 to 3 minutes of a phone call my phone is getting hot on my ear. I have took the case off from it to see if that would help. I noticed the back and sides of the phone were hot too. It’s annoying just a little usage of my iPhone and get really hot. I even checked to stop all apps running. My phone is still getting hot within a few minutes on a phone call or face time etc.

It's amazing how my iphone 15 pro 256GB blue is working so well without even getting warmish, it's getting hot only for level1s, well sure I'm a level one too but nobody over this level, with no picture, well fair enough I didn't bother with a picture too....but nobody has a overheating iphone if has uploaded a picture...and is over level1

OK.....just what do you think complaining here is doing for you? NOTHING. Complain to Apple. This is a user to user only forum.

Facetime, nor streaming music, nor making phone calls is causing ANY heat on either our iPhone 15 Pro or 15 Pro Max. NO HEATING AT ALL. If you are still experiencing heating, take it to your Apple Store for testing. Or wait for the update Apple has promised to release soon. Your choice.

Yeah thats what I think so. Although I'm still surprised at the heat, especially compared to my older phone when its on 65W fast charge. Also I think having it on 5G is also causing the heat issue, since on WiFi before it was nowhere near as bad. Hopefully this is fixable in a software update.
