13 Pro here, and after upgrading to ios17, I noticed my phone was running very hot, screen was dimming all the time, and battery life was suffering. It resolved itself a couple days ago. Sucks that we can't really get any visibility into what apps are causing the issues...can't exactly load a terminal and run top.

Kinda puts a wrench into Apple's whole "side loading apps would be a disaster!" thing...I mean even with the walled garden you have situations like this where they are approving apps for the App Store that have the potential to ruin the user experience with the device.

I believe this is a software issue though and not related at all to any specific chips or chip issues; at least it was for me.

…what? Apple doesn’t want to allow side loading because of privacy and security issues, not because bugs exist and sometimes performance isn’t optimized. AFAIK there are no requirements that apps in the Store run perfectly under all conditions, nor is that a realistic expectation.
 
Titanium has poor heat conductivity I believe, so did Apple used their $$$$ to create a new kind of Titanium alloy that is not like this?

I believe if Apple made the iPhone 15 Pro Max out of Aluminium, the phones would be less likely to overheat.
 
Every day, perhaps a few times per day, I go through and close all the apps on my phone. No overheating issues yet. It got a little warmer when I was setting up the iPhone 15, but no issues since then. I don't know why I have to close the apps myself, they should just close themselves after non-use for a certain amount of time, but if that's what I have to do..... It's a great phone and nothing, and I do mean NOTHING, is ever going to be perfect. That's life!

Apple put out some document a couple years ago where they touted how great their app review was and how you wouldn't get that with side loading or 3rd party app stores. Not so great now, when they're approving "high quality" apps that cause your device to heat up to the point where it could almost burn your skin.

The reality is, if this were happening with a 3rd party app store or side loaded apps, the response would be the same. The developers would be doing what they're doing right now, working to fix their issues.
 
How is the iPhone 15 Pro/Pro Max overheating not a hardware issue? It's the A17 Pro chip that's generating the heat, is it not? If the A17 Pro chip is not hardware, then what is it? It's certainly not software.
iOS has shown heat problems on older hardware too. My 14P gets hot anytime the camera is turned on. And really hot if it's on a long time. (like when the camera is turn on inadvertently when I put my phone in a pocket, which happens at least a couple times a month.)

You don’t have to manually close apps. iOS automatically closes them when it determines the app no longer needs to be open. Having the apps show up on screen when you swipe up doesn’t mean they’re open and running. There’s no benefit to closing them manually.
 
No, the 14 Pro was machined from a block of stainless steel, with the components attached to the back. With the 15 Pro, Apple rearchitected the entire device to have an aluminum midframe fused to the titanium rail.
Exactly.
Titanium layer is quite small (~1mm). But their fusing result is quite masterpiece of engineering.

There is a small rim of titanium around this phone. The vast majority of the external surface area is glass and on the inside it sounds like most internal components are next to aluminum not titanium.

There was never any plausible way that the switch to titanium was significantly impacting the thermals of this phone.
