iPhone 15 Pro Max Thermalgate (yup, it's happening): Pics of how you're coping

bmustaf said:
Really disappointed that the things my 14PM did without any problem/complaint in room temperature environments (you know, just basic stuff like syncing the day's iCloud photos, charging on the reg) now involve "iPhone needs to cool down". I've thrown out all the wireless chargers to try and help reduce heat, but that's not really helping much, either.

My 15 max will get warmer (And I emphasize warmer, not hot) when I have the camera open. A geekbench run didn't heat up much either, never have I found it anywhere close to be to hot to hold.

I am surprised just having the camera open heats it up, but I guess it is doing quite a bit of processing, this is my first iPhone in a while (since a 6S I believe) so maybe that's the norm.

I have no clue about chip manufactoring but isn't a transistor leak something QC should find?

Yes, but a die can be used if it's out of spec. This is known as die binning. In die binning, dies are sorted based on their performance and quality. Dies that meet all of the manufacturer's specifications are placed in the highest bin, while dies that have minor defects are placed in lower bins.
Dies from lower bins can still be used, but they may have lower performance or be more likely to fail. Manufacturers will typically sell dies from lower bins at a discounted price.
For example, a die that is out of spec on its frequency may still be usable in a less demanding application. Or, a die that is out of spec on its power consumption may still be usable in a battery-powered device.
Apple owns TSMCs N3B process and no one else is taking products from it. It's yields are 55% currently. Given the chip shortage and high demands, it would be very enticing for Apple to use dies in a lower bin.

When I charge my 15 pro and my car, it gets very very hot and it won’t open emails or any webpages. It’s very frustrating!!

What’s the setup? This happened with my 12pro and happens with my 13Pro. If charging and using maps, music (esp with 5G), plus near a warm area, vent, or greenhouse effect from the windshield you will get a hot phone with any phone
 
I was curious and I ran a 20 minute 3d mark benchmark test. I figured if that didn’t cause it to overheat I’d be ok. It got warm to the touch. I could feel it got warmer but it didn’t burn me or I didn’t need bbq gloves or a case. It was warmer but just warm to the touch. Even when I fast charged it on the Apple 20 watt charger it just got warmer to the touch. Out of the two explanations, thermals or some chips not made as well I would go with chips. If it was thermals all iPhones would be hot. but it is only some so hopefully the yield of higher quality chips increases.

For me the problem is now just with calls. It begins to overheat on calls longer than 5 mins.

Just tried to call (room to room) an iPhone 14 still on iOS 16:

  • iPhone 15 Pro - 10 mins call 5 points of battery lost - overheating
  • iPhone 14 - same 10 mins call 1 point of battery lost - cold
An 1 hour call yesterday depleted the battery by 30 % points.

iPhone 15 Pro not overheating is low power mode enabled.

Yeah that's not normal. Try resetting it as new and use it without retrieving any backup and see if it does the same. If not return it. I've been doing cell phone calls and FaceTiming and mine is still cold and loses 1% after 10 minutes.

I’ve never had this with any recent phone (12,13,14) just the 15 and mainly the pro. We have 4 in the family. 2 went back (both pros) due to excessive heat - both natural. Was just routinely charging in the car with apple cord. Wondering if it’s usb related?

This is one wild speculation, one out of many in this thread.

Honestly, I'm quite fascinated by the problem --> analysis --> conclusion process demonstrated by some of the members here.

- We have no idea what is failure rate (%) of iPhones out there. It is tempting to draw premature conclusion based on the anecdotal reports here and elsewhere, but in reality it is a poor proxy to the actual failure rate, for obvious reasons.

- We have no idea what is the underlying cause of the issue. It could be software, hardware design, manufacturing or a QC issue. It is entertaining and easy to speculate, but where is the evidence or the logical chain of facts that supports these speculations?

Let us be patient and gather more data before we come into premature conclusions or speculations.

Not sure - let's explore the major scenarios:

- If this is a software issue, it will be resolved for all
- If this is a QC issue, the affected units will be replaced
- If this is an inherent hardware design flaw (very unlikely scenario), there will be a recall

Perhaps there are a few more scenarios, but in any case, I don't see a situation where Apple won't address this issue for the affected customers.

I do agree that a replacement would result in an inconvenience, but so would returning the device.

that's why I got a plus for now (or may just keep it) no issues whatsoever with this one! lol

I think these issues, so-called are overblown. If anything I would cast the blame on Apple adding an additional CU for the GPU this year, we saw with the M1/M2 Pro and Max that having more CUs decreases battery life even when the GPU isn't being stressed.
 
We have several many iPhones in our family, old new ones, and all of them got very hot when using while charging post updating to iOS 17. To the point where you get the "iPhone needs to cool down." prompt.

A few days after the update this stopped and they can now be used while charging without getting hot.

🤷‍♂️
 
My 15 Pro Max seemed a tad warm during the transfer from my 14 Pro Max. This is not unique though, as it happens every year in the hours after setup while all my apps redownload. After that it was operating as normal.

I think my iPhone to iPhone transfer is several years old now and I'm having zero issues with iOS or my 15 Pro Max other than I keep wanting to mess with it and not work.

Oh yes, absolutely wild speculation. But, since Apple hasn't commented at all, this is what happens. :)
 
My 15 Pro has been great - got warm during the initial transfer from my old phone, but almost a week in and it's been cool the entire time (no case, either). That said, I don't game on it or anything - just typical phone consumption stuff.

I just did a 10 min phone call with my wife to see if this was happening on my Pro Max. Cool to the touch after 10, and not even a single % point lost.

I would take your phone back. There's something wrong with it.
