iPhone 15 overheating

Apple specifically said when iPhone 15 was released it might run warmer during the first few days as all the millions of bytes of data are indexed. And when you charge an iPhone, it should get warm normally. Batteries get warm when being charged. That's physics.

When you purchase the forum, you can direct who can comment or not. Until then, I'm just as welcome to post as you are.

As I've said my iPhone 15 Pro and 15 Pro Max are NEVER operating too hot. They don't have any battery drain issues either. This is NOT an universal, it effects every user thing. If someone does have these issues, instead of complaining on a user to user only forum, maybe it would make more sense to have the phone checked at their closest Apple Store Genius Bar. As users only, we can't determine what might be causing heating or battery drain issues from our sofa. Have the phone checked out where Apple can determine if there is an issue.

Hi - I purchased the iPhone 15 at the end of November 2023. I had no issues initially, but while on holidays over the past 2 weeks (mid Jan 2024), the phone got extremely hot, during which time the battery drained extremely rapidly. When I later plugged the phone in to charge, an onscreen message stated “Charging on hold. Charging will resume when iPhone returns to normal temperature”. I thought maybe I was using it too much, being on holidays, but nothing over the top showed up in the battery settings. This happened a couple of times while I was on holidays, so I booked an appointment at an Apple Store. A diagnostic test was run and no problems showed up. I think the technician mentioned a new type of battery, or a new part or something, which means this iPhone will be different from previous models (sorry, I’m not sufficiently tech savvy to understand exactly what he meant). Anyway, basically, the advice was: the phone is operating normally, so no need to worry.

I’m back home now, and the same thing has happened again. This time I wasn’t even using it and it overheated. While it was hot, it wouldn’t send text messages, calls weren’t received, and it didn’t seem to charge - although no onscreen message this time. I had to turn the phone off and on again to basically ‘reset’ it. So, considering I’ve had the phone for close to 2 months, I don’t think it has anything to do with indexing data; the voice over has always been set to off; this phone has 128GB storage capacity, which is double the capacity of my previous model - the iPhone 12 mini , which never had this issue; and all system software updates have been installed.

I’d really like to know what the cause of the overheating is, and if there’s something I can do to prevent it from happening again.

Got to be careful if articulating that the phone is overheating while off. That would imply a live current or it shorting and this is frankly unheard of. Alternatively you are describing a lithium ion runoff event and that is a different issue such as those affecting former Samsung phones. I recommend to call in, until then the entry generates skepticism. Apple iPhone runoff events are - for new phones- uheard off out of the billions of units sold. I once had a brand new MacBook Pro with a battery defect and it swelled the aluminum casing and the Genius folks took the unit away in a heartbeat, permanently.. got a new one.

EVERY TIME you plug your phone in to charge it WILL get warm. This is completely normal and when you charge a battery the battery heats up. I think people are worrying unnecessarily here.

I have the basic model iphone 15 and its doing the same thing especially while charging , husband has the iphone 15 pro and heats up as well.

Well my iPhone 15 pro is ok now no more hot phone if you are a Vodafone customer do a battery refresh worked for mine

Hello, if you are so worried I'd suggest you to book an appointment with the Apple store immediately

If it happened to me I’d have gone to the Apple store ‘yesterday’ you know what I mean it’s a toy costing over $ 1000 so I’d have asked for advice immediately

...and you didn't take it back to the Apple store of course?

Either way the issue is real and part of an acknowledged bug in iOS 17.

And software bugs are fixable.

I try using the low power mode and it still getting warm but not so hot

It’ll be a fix in the next IOS 17 update and an update of the apps causing the problem

They have said that the reason for the overheating was something about the iOS 17 update
