Apple Says iPhone 15 Pro's Titanium Frame Does Not Contribute to Overheating Issue

[Charon_Sin]

" In fact, Apple said the titanium frame and aluminum substructure provide better heat dissipation than any previous-generation Pro models with stainless steel frames"

uh, does it really ?

Well Titanium not really but the center frame portion with all the parts mounted on is Aluminum and Aluminum is 5 times more conductive.

The entire frame (the metal part around the phone) is titanium. Only the "substructure" (the "interior" portion of the chassis to which the components are fastened) is aluminum. This has been verified independently as well...

I was surprised to see so much titanium. and those scientific test are spot on with Apples claims as well.

No, throttling is almost always present by design. Without throttling, you'd have slower hardware or much bigger devices.

Allow me to clarify myself. Throttling is necessary without sufficient cooling, which appears to be what Apple will need to do to correct this overheating problem with the 15 Pros.

I don’t think its the Titanium frame, but bear in mind that the frame is not pure Titanium, its not an alloy either but closer to Aluminum coated with Titanium.

JerryRig cut apart a 15 Pro Max and the outer frame of the phone is solid Titanium (all the the visible metal) the inside of the phone is aluminum.

So why does my phone heat up like a Spirit Airlines gate at Miami when i UPDATE my apps in the App Store app?

This is totally an OS issue.

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.

I'm sure the heatsink isn't made of titanium, only the frame.

The only time my phone runs even slightly warm is when I’m reading content on this site, and this site alone. The amount of programmatic ad bidding as these pages load is just completely obnoxious.

We don’t have these apps.
My wife and son 15 Pro could boil water.
They went back today.
Let someone else be a Guinea pig for Apple.

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.

Solution - iOS 16.

 

[lindros2]

But wasn't it stainless steel+aluminum before ?

But the frame isn’t directly connected to the SoC or battery. Those numbers are scientific, but theoretical.
With war scars from both 15- and 16-inch MacBook i9, I’ve lived through Apple thermal issues.

 

[marzbarz]

you mean people complaining were all wrong

who knew

 

[unclemax]

Now the question is, who fed Kuo that garbage about titanium? Was that an honest mistake? Or is there some effort by Chinese nationalists to subvert Apple. They got so butthurt by huge demand for iPhone 15 Pro in China, and lukewarm reception for the Huawei’s subpar sanctions-buster. I’m not saying it was, but could’ve been a psyop by the masters of TikTok.

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.

If it were purely hardware it would be a more universal problem. That’s how.

Thanks Apple, but the issue started after 16.5.1 update and isn't isolated to the 15 Pro Max. 13 and 14 pro maxes are also affected. And let's not forget about the battery.

I don't think this can be safely said. I've gone from 16.x up to 17.0.1 on my 11 Pro and have had no issues with heat or battery life.

BL.

Put a case on it lol

I have described my experience on 13 Max Pro. I have never had any issues with any iPhones starting with iPhone 5. The forums and Reddit are full of similar reports about the 14 and now the 15.

Sia/gueatta will sleep tonight Titanium is real.

 

[sehns]

These days its really hard to know if this is just PR BS or real or not. Remember "You're holding it wrong"?

Consumer Reports says the iPhone 15 Pro Max is rock solid.

They don't do massing processing, but it isn't about that. It's about bugs. A very simple app can overload the phone with a bug that keeps CPU at 100%.

Both are supposed to be mature apps, so hopefully Apple makes them fix their apps or remove them from the App Store.

 

[svish]

Glad to hear that the issue can be fixed by a software update and that it is not a hardware issue.

But wasn't it stainless steel+aluminum before ?

The point being that the 14 pro with stainless steel frame had worse conductivity than the 15 pro with titanium.

My 15 pro got hot on the day I set it up while the OS was updated, the files were transferred, and a few hundred apps reinstalled. Once that was done it settled down and was not notably warm. When it was warm, the heat was not coming from the metal frame but from the glass back. It doesn’t seem that the frame has much affect on the heat dissipation after all.

I believe if Apple made the iPhone 15 Pro Max out of Aluminium, the phones would be less likely to overheat.

When has the frame of an iPhone ever been a significant part of the heat dissipation of the phone? The times my phones have gotten hot it was always the back that was hot, never the frames.

 

[Tagbert]

But Grade 5 titanium is actually only at 6.7 W/m-K.

ASM Material Data Sheet

How is the thermal conductivity of the outer frame relevant? It’s not being used as a radiator.

 

[flexwithmarius]

I think it’s just sloppy work by companies that should know better but don’t care (Meta anyone?)

A storm in a teacup.

The OS/apps/hardware performance will be refined via software updates over time.

Apple have stated that chipset performance will not be hobbled to resolve issues- which is good news

or worse…the offending app companies want to put Apple in a bad light so they intentionally made their app go haywire. but that’s just heresay.
