I wonder if it’s anything to do with using a case. Since it’s a bit random that is.

My 12 pro max in a thin silicone case can’t even handle being wirelessly charged with magsafe on a sunny day without shutting itself down into pitifully low brightness mode.

im no apple proponent but i have used the xr,13 and 14 in full cases with no heat difference

Thermal Conductivity I wonder if this is related to the use of Titanium and the poor thermal conductivity of Titanium (17 W/m-K) vs. Aluminum (210 W/m-K). Aluminum dissipates heat more than 10x better than titanium. https://waykenrm.com/blogs/titanium-vs-aluminum/#:~:text=All... . --- EDIT: I no longer think it's thermal conductivity due to the change in metals. See below. https://news.ycombinator.com/item?id=3770515…

The amount of titanium in the iPhone is about a 1-2mm band around the outside. The inner chassis is still aluminum, and they are diffusion bonded together. While that Ti is at the primary thermal boundary for the metals in the phone, I would guess (judging from experience with both stainless steel and titanium banded phones) that most heat escapes through the glass front and back of the phone, even though they have p…

Just to confirm, it’s almost exactly 1 mm, and the aluminum part it’s welded to adds about another millimeter: https://youtube.com/watch?v=S_W73ouKtjU&t=9m44s

(That’s for the Pro Max. The Pro could conceivably be slightly less.)

What you can do as a consumer is.. not buy new iPhones?

I don't mean as like a protest or anything. I mean just don't buy your iPhones new. They don't change much anymore, you can get caught out by this or Antennagate (or any other type of issue you get to encounter as a first mover), and the changes between years are genuinely minimal now.

The iPhone came out in 2007. The iPhone 4 came out in 2010. The leap from the original iPhone to the 4 was absolutely worth buying a new device over IMHO. A lot changed in those 3 years. Not much of anything has changed in the last 6. Not really. It's still basically the iPhone X with a couple of screen size options. Yeah the chips are faster on paper, and the photos have gone from really good to better, but it's a really incremental product these days (the notch has a notch now).

A used iPhone 13 Pro Max in great condition is about $450 these days where I am.

A new 15 Pro Max is about $1200. I get that they're not the same device, but is it really 2.1x the device that the 13 is? Am I the only person that thinks about it this way?

I get that I'm no fun at parties, you don't need to tell me. I'd probably tell you to be honest, were I invited, which I rarely am.

A related issue exists with M1/M2 Pro and Max chips in their laptops. They do not overheat (unless you're in a hot environment) since they have fans and seem to have included enough cooling for these chips, but you do not get the miraculous battery life with these that you do with the lighter versions. I guess they made the chip and RAM a lot bigger but didn't make the battery much bigger. The battery life is still d…

You should investigate your battery life. I have an M1 Pro (14" even) and I consistently get 10-12 hours on a fairly heavy developer workflow.

On a laptop it's probably some out of control javascript taking a few cores to 100%.

But on a phone it should throttle?

Earlier quoted context omitted.

I do think "normies" care about the CPU is hot or not, but they do so indirectly, as the phone will start throttling the CPU when it reaches a certain temperature, so the phone will start feeling laggy. If you've ever tried to play a game on the iPhone/doing something else CPU/GPU heavy while outside in the sun on a hot day, you'll know what I mean, the performance is much worse.

> If you've ever tried to play a game on the iPhone/doing something else CPU/GPU heavy while outside in the sun on a hot day good excuse to put down the phone and enjoy the sun :)

Some of us live in places where there is more sunny & hot days than not, and your advice feels geared towards people who don't live such places ;)

So I have the iPhone 15 Pro Max. I have for sure had a few times that it got really hot, particularly when I was restoring it and it was doing a lot of background tasks. BUT so has every other single iPhone I have had since at least the X but I am pretty sure going farther back. There were always moments that it got hot and I remember it would always happen when I was first setting it up. For me at least I don't thin…

I have a FineWoven case on my 15 Pro Max and, just adding to the anecdata here, have not had a single thermal issue. The only time it warmed up was during the initial data transfer. I'm pushing the phone with a lot of cinematic video recording, etc – remarkably cool.

I watched this story blossom out of a few social accounts I had to mute because it started to feel like they really wanted to get likes on 'iPhone 15 Pro Max is a disaster' type posts.

That's the tricky thing about the information environment we're in. A real issue affecting people? Or a non-issue that's being boosted and then picked up into a bigger story. Devices sometimes have issues – not debating that. Just saying, I feel like there's been very little skepticism applied here.

Since titanium covers the whole back and sides, wouldn't it act as a "thermal bottleneck" regardless of the aluminum?

Titanium is only the outer band. The back is glass.

Thanks, I wasn't aware of that.

This is some kind of bug with throttling not being applied i guess, but I'd very much like Apple to test their devices outside a constant temperature dust free office.

Right now it shuts down when it's too cold (and i mean like 0 C from personal experience, in my stopped car in winter), shuts down when it's too hot (car in summer). Keyboards fail if you dare to use them outdoors and are irreplaceable.

Can they afford to use their devices in the real world a bit before launching? Not everyone always keeps their phone at a traditional office 18 C...
