Apple Releases iOS 17.0.3 With Fix for iPhone 15 Pro Overheating

Just updated my 15 pro max to 17.0.3 and it’s legitimately warmer than it was on 17.0.2 🤣

I shut down after updating and let it cool down. Now its back to being warm.

Mine was warm for a few minutes after the update and now it’s back to the temperature it was before.

Just let it sit and do its thing.

Apple today released an iOS 17.0.3 update for the iPhone, with the software coming a week after the launch of iOS 17.0.2. Apple has also released a new version of iPadOS, 17.0.3, for iPad users.

The iOS 17.0.3 and iPadOS 17.0.3 updates can be downloaded on eligible iPhones and iPads over-the-air by going to Settings > General > Software Update.

iOS 17.0.3 addresses a significant overheating issue on the iPhone 15 Pro and iPhone 15 Pro Max. Shortly after the new iPhone 15 models launched, customers began complaining that the iPhone 15 Pro and Pro Max were getting too warm, and even shutting down due to heat problems in some cases.

Apple confirmed that there was a bug in late September, and said that it would be fixed with an update to iOS 17. Some third-party apps had also been overloading the A17 Pro chip, leading to problems with heat dissipation. Apps affecting performance included Instagram, Uber, and more, and in addition to releasing an update to address the iOS 17 issue, Apple has also been working with app developers to optimize apps causing problems.

In comments to MacRumors, Apple clarified that customers experiencing temperature problems would see the issue resolved with an update, and that the titanium frame of the iPhone 15 Pro is not at fault. Apple analyst Ming-Chi Kuo claimed that the overheating was likely caused by "compromises made in the thermal system design," and he suggested that Apple would only be able to fix the issue by lowering processor performance.

Apple said that it has no intention of tweaking the A17 Pro chip, and that the titanium and aluminum design of the iPhone 15 Pro in fact provides better heat dissipation than the stainless steel frames used in previous models.

The iOS 17.0.3 and iPadOS 17.0.3 updates also address a kernel vulnerability that could allow an attacker to gain elevated privileges. Apple claims that it is aware that this security flaw was exploited on versions of iOS before iOS 16.6.

Why are you so desperate to downgrade? 17.0.3 may be worse than whatever is happing to make you want to be off 17.1. You even only wanted 17.1 B2 to allow you to downgrade before even knowing if it was good or bad. Just curious.

Because since I have updated to the beta it has been getting hot. whwn I was on 17.-2 it was fine. I have been trying to downgrade ever since. You were not able to go back to 17.02. So especiallly now I want to use 17.03

This update almost gave me a heart attack. Was in the process of updating and then requested to rest my phone

Instead we have scorched faces because the phone was burning hot when using it as a phone.

You're using it wrong.

Like I said in other threads, it appears that this is best used for:
  • the power source for your electric blanket;
  • your space heater; or
  • the burner/stove for your wok when you make egg fried rice.
Please be sure to use your iPhone 15 Pro and iPhone 15 Pro Max properly.

:p

BL.

Some people were reporting heating when on phone calls and such. My guess is there was some background process that would peg the CPU and make the phone hot. They probably fixed it so that would only run when plugged in, or throttled it to not use so much CPU at the same time.

This is a pretty common issue; for decades I've seen processes get stuck in the background in a tight loop wasting CPU and energy. It's happened on Windows, Linux, MacOS, Solaris and more. A very common bug, and the fix is usually easy.

Maybe some of you guys who've been here for years can chime in but... it sure seems like there's way too many updates these days compared to ten years ago. Seems like every few days, there is a reported issue, then I have to sit through another update. And another, and another, and another and... it's just out of control.

You could just get a Samsung or any non google made Android device. You will then only get a few updates a year.

You wouldn’t have to suffer the pain of putting your phone down for 5 mins every few weeks.

It's amazing to me that users have kept gaslighting those who encountered the issue: "it's just warm. that's not overheating"; "it's indexing"; "you are using it too much"; "no issue with mine"; "first world problems"; "just be grateful"...on and on and on. The issue is with Apple's end all along. Even Apple admits it. Next time, just accept that some people might have problems with their devices that might not be happening to yours, and that the problem could be with Apple and not the users. You can believe other people's complaints and still be happy with your own device. Don't take it personally.

That, and insisting that there is no impact on battery life of older phones (which have also been getting hotter than usual). How ridiculous to assume that energy came out of nowhere.

I mean, think about it.

What are they gonna do? They have two choices if there actually is a design problem.

1. Admit to a design issue on the newest iPhones, issue recalls and spend millions on replenishing recalled devices with new models, spend additional millions on new engineering, new frames and manufacturing and halt all iPhone sales until they're out.

Or,

2. They could just brush it under the rug, lie about it, throttle the processor secretly, get a bit of bad PR but continue selling millions of phones this year.

I'm not saying there is a design problem, all I'm saying is that there is a much easier choice out of these two.

The easiest choice is to recognize that Kuo is a blabbering buffoon who doesn't know what he's talking about.

compared to 10 years ago, there are more features and more code, so hence more updates to fix them. Also with any MAJOR code update that adds more features you always run into more bugs. Apple like any company tests as much as they can and they listen to Dev and Public feed back on the code testing. Also deadline for getting the code out, security fixes that need to come etc,etc. its all a balancing game

So I guess it comes down to whether or not we think all these updates and bugs are worth it. Because looking back to iOS 6, the first update didn't come out for two calendar months. Then it took three whole months for the next three to drop. There was also a total of just ten updates during the course of its lifespan. Compare that to iOS 16, where you get the first three updates in less than a month, and twenty updates overall. It's just insane. We're bathing in updates. It's almost never-ending.

Is it worth it? I don't know. I had a 4s. It didn't do what my newer phone does, sure. But I can't say I'm doing much more on it personally than I was before. So I'm not sure the benefits outweigh the hassle for me.

Perhaps the software is far more complicated than ten years ago and more difficult to tune it perfectly.

Dang really? Maybe it’s just indexing again.

To be fair, it is true that a new iOS/macOS installation comes with significantly increased background activity in the first few days, then after a while things calm down. That being said, you're right in that there was also a bug in the OS that in some instances contributed to the problem(s) as well.

Any videos out yet that compares CPU performance before and after this update?

Probably some new routines that allowed background processes run amok on the new chip. When Instagram and others were called out that made the most sense which can also be bandwidth heavy. Simple change on both ends. Also don't conclude immediate warmth after upgrade as not-corrected, there is the re-indexing after upgrade stuff so give it a little time.
