iPhone 15 Pro Overheating Concerns Highlighted in Two More Reports

Given the iPhone 15 and 15 Plus (non-Pro) are based on the tried and tested A16 from last years 14 Pro, I am guessing these are not impacted? I have an iPhone 15 (non-Pro) and not experienced heat issues but just wondered if anyone else has.

Seems like the issues are related to the 15 Pro and 15 Pro Max models only, which are based on the 3nm A17.

The problem with this, which I'm sure has been mentioned, is "hot" is so subjective. So we're going to get skewed anecdotal reports as this "goes viral" and the problem will be blown out of proportion. Not saying there's not a problem, either.

It also could be as simple as some rogue app or process that's running in the background that's easily fixed by a software update...

I don't buy into "overheating" hysteria. 99% of the time people conflate "getting warm" to "overheating" because they don't understand that chips get warm when doing things and what sounds hot to a human isn't hot to a computer chip.

If it's truly overheating, the screen will dim, the device will stutter, and eventually shut off. That's overheating.

Doesn't it also give you an alert? I mean way back with my iPhone X I saw that message just once in the car and yeah it was really hot day and I got in the car the air just turned on. It was like an oven in the car. I just put it next to the vent to cool it off.
 
My 15 Pro gets very hot during charging. Have not yet carried out intensive tasks, so it hasn’t felt any warmer than expected in general use.
 
The highest CPU usage I’ve seen is 55% (using Sys Status Pro). Even Instagram videos seem to only tax the CPU about 25% so nothing crazy. I’d bet that there’s some weird checksum in the previous iOS version that gets messed up with the migration and never gets cleared up. Upgrading even after probably doesn’t fix it. Only upgrading before migration will circumvent this phenomenon
 
My iPhone 14pro would get hot regularly. Sometimes when charging, sometimes with the camera. I also noticed that when it got hot like that the battery drained way faster. Many times I already had to recharge by late afternoon, meanwhile the iPhone 13pro, I usually had all day battery. Let's see how my 15pro performs. BTW I did at one point take the 14pro in for diagnostics, and passed all tests.

I know Apple didn’t have the results they wanted when they tested a vapor chamber a couple of years ago, but they may have to revisit that for future iPhones.

I guess I've been lucky. My 15 Pro Max has barely gotten warm, much less hot.

I've noticed a couple times my new 15 Pro Max got noticeably warm (as in - not scorching hot, but warmer than I was used to my iPhone 13 Pro getting in similar situations/conditions). But it hasn't prevented it from working normally, so far.

(My iPhone 13 Pro would regularly report charging stopped because it got too hot, if I tried to charge it while using it in my Chevy Bolt, in the inductive charger "pocket" they provide for phones.)

I'm sure a lot depends on what you have your phone doing. I doubt there are "some iPhone 15 Pro Maxes that get much hotter than others". Most of us probably just aren't running the right combination of apps, doing the right functions to reproduce the issue others are running into.

"Apple refused to comment."

Lack of transparency is a huge problem. I understand that there are liability issues and the Class Action lawyers will come out in full force, but it's not comforting to me, as an Apple enthusiast, for the company to " remain silent." And, I imagine most of the general population will feel the same way. No one wants to spend $1,300 on a compromised phone.

That literally says how they are. Apple addressed the bendgate issue from iphone 6. Why couldn't they literally say "We understand that there are issues regarding users and purchases with temperature in our Iphone 15 and we are working on a fix as soon as possible."

How can a company literally screw up by not admitting they're at least working on a fix for this?

I have not seen much on the topic of ios17 being the potential problem... Since updating to ios17 and ipados 17, I have noticed both my mini12 and iPad Pro have a greater tendency to get warm to the touch just doing basic things like scrolling through Reddit. A couple days ago I also had my iphone get warm enough while in my pack that I felt the heat on my skin. I took it out expecting the culprit to be the camera got accidentally turned on again (this has happened many times to me), but not this time... nothing was running, it was on the lock screen, and quite warm.
 
If it’s a stuck process apple will figure it out quick with all of the usage and analytics data they have beaming back to them.

My 15 Pro actually runs cooler than my 13 mini did over the last few iOS 16 updates

13 Mini user here since start of this year. I’m curious, under what circumstances/ Apps did you find the Mini running warm? I know you didn’t say hot or warm but rather the iPP 15 running cooler.

iPhone 15 Pro and Pro Max overheating concerns continue to make headlines this week, with the topic highlighted by The Wall Street Journal and Bloomberg.

Both of the reports document anecdotal complaints from customers, and outline potential causes, but it's unclear how many devices are actually affected. Bloomberg said the overheating could be caused or compounded by the iPhone's setup process, suggesting that the higher temperatures might sometimes be a temporary condition.

The Wall Street Journal quoted a customer who felt his iPhone 15 Pro Max remained hotter than his iPhone 13 Pro Max a few days after setting up the device:The Wall Street Journal's Joanna Stern said her iPhone 15 Pro Max did heat up while charging and performing processor-intensive tasks, such as gaming, but she said her iPhone 14 Pro Max reached similar temperatures in the same test. During typical everyday usage, Stern said the temperature of both devices was in a normal range. Many customers on social media have also said their iPhone 15 Pro is not experiencing any overheating, and the lack of hard data makes it unclear if there is a widespread problem.

On Wednesday, Apple supply chain analyst Ming-Chi Kuo said the titanium frame on iPhone 15 Pro models negatively impacts thermal efficiency. Kuo believes that Apple will likely address the issue through software updates, but he said improvements may be limited unless Apple lowers the performance of the A17 Pro chip.

Apple has not commented on the concerns, and it's unclear if the company will actually make any software optimizations in future iOS updates.

Not a real fan boi here but I take with a gram of salt...and several licks of a salt tree, anything Bloomberg but ESPECIALLY anything the WSJ say about the slightest 'negative' news/rumor concerning Apple.

This is a pure hardware chassis issue. I've worked with titanium and am well versed in its use on the SR-71.
Titanium was chosen for the SR-71 because it has a high heat resistance, a high melting point, mechanically rigid and resistant to damage, and absorbs heat quickly and dissipates it quickly.

So, at Mach 5, the friction of the air flowing over the fuselage of an SR-71 would heat to a very high temperature and make the Titanium flexible and bendable, but maintaining its form. It also allows for the machine to cool rapidly, as the titanium is a poor conductor of heat and loses it almost as fast as it gains heat. Which means if the machine started to superheat, you could reduce speed and use the altitude's outside temps to cool down rapidly.

There was one massive flaw....when Titanium superheats, it becomes like playdoh....it can bend and stretch without losing structural integrity, so oftentimes it would form small bends where fuel could leak. The SR-71 after only one or two deployments could easily lose most of its fuel by leaking and use of afterburner before and during takeoff. It would need refueling in the air and then the aircraft could accelerate and gain altitude.

So, this explains both the bending and heat issues with the titanium iPhone 15 Pros. Titanium absorbs heat quickly and loses it quickly, but in doing so, the titanium becomes soft and pliant, prone to bending and morphing.

Apple would know this....at least they should if they are truly using aerospace grade Titanium, or Ti-6AL-4V. However, that is ridiculously expensive and is used in the production of high bypass turbo-fans (commercial jet engines), wide or thin body airline structural components, military applications, etc. A step above that is surgical, for use in medical surgery environments.

It is more than likely CP-3, or Commercially Pure, Grade 3, the cheapest Titanium usage that is aerospace grade. And the Ti-5Al-2.5Sn used in the SR-71 would have a higher heat tolerance than CP-3, being an Alloy. So, the phone is heating and bending because Stainless Steel and glass absorbed the internal heat slower than the titanium does.

I did not realize an iPhone 15 pro is capable of reaching Mach 5, or have its temperature raised to 600 degree F where it will superheat the titanium chassis.

one example is that wired CarPlay using maps (GPS) and Apple Music would heat the 13 mini a bit. I mention that because I was surprised this Sunday when my 15 Pro wasn’t really very warm after a one hour drive using CarPlay for maps and music.

The 13 mini fit in the little cubby under my stereo a lot better though…
