Kuo: iPhone 15 Pro overheating due to compromised thermal design

27 September 2023
Apple went too far with the weight reduction of the cooling system.

Same thing they did with the M2 series of MacBooks. As a lifelong windows user, I was very tempted by what the M1 presented and decided to get an M2, only to find out it's actually worse in many aspects than the M1, and finally decided to go with an M1 Max 16". A friend of mine who's always been a Linux user did the same thing.
I think it's better to always wait before getting the latest thing since companies sometimes are overly optimistic with their designs. Even Apple, despite being famous for having a rigorous quality testing process.

      "" The only way to actually prevent a phone from overheating with a software update is to limit its performance and in turn power requirements so it generates less heat. ""

      Are we really sure of this? I mean, can't we disable some background tasks and have different RAM management and optimise stuff, improve video codecs and all.
      I mean, non slowdown solutions exist, right?

      If a phone heats up on its own, while its NOT gaming or encoding heavy videos, its defective in my opinion. Have to see in person to see how severe it is with iPhone 15 Pro.

        Apple had claimed that the overheating is caused by a bug in iOS 17.

        Let's wait for the next update and see if this is true, though.

          i'll just slap an rgb aio cooler on it, np.

            Anonymous, 30 Sep 2023Correct, titanium has lower heat conductivity than aluminum... moreTitanium is a bad conductor, is heavier and is also very expensive and environmentally unfriendly to produce compared to aluminium. But kudos to Apple's marketing team.

Along with that, I also assume that the glue bond between the Ti frame and Al body acts as an additional layer of insulation making the situation even worse...all in all, the titanium isn't a good idea at all, compromising performance and strength while just being another marketing gimmick IMO.

Most benchmarks are done on release after all, so many people won't even notice..

                  This heating issue is strange, you would think that Apple's QA testing would have detected this heating issue... unless Apple though that it was not an issue.

                    Dear GSMArena team, who told you that titanium has higher thermal conductivity than aluminium?

                      With this thermal issue, prolonged use of the iPhone Pro, in particular in warm environment, can result in the lithium battery bursting into flames.

                        protective case anyone?
                        i always wondered whats the point of cooling solitions if everyone put cases on their iphones, reducing cooling even further.

                          A person only few people can trust.

                            Don’t worry, Apple will FIX the issue with software update by underpowering the A17 Pro chipset’s processing :) /s

                              [deleted post]Yeah I was just jesting, gaming phones are not my thing is all. But then I tend to roll my eyes anytime I see the word ‘gaming’ when it isn’t immediately followed by the word ‘console’.
                              For those that are into such things, I can’t argue that the 7 ultimate isn’t an absolute beast of a unit. I just happen to think it’s an over engineered solution to one of the least important uses of modern smartphones, and looks like something that belongs up Optimus Primes nose 🤷

                                  Don't worry that is overheating.. That's fine it will keep you warm apple was thinking already in advance.. The winter is coming

                                    most of the heating I saw happens in carplay (screen mirroring) navigation with music streaming while charging in the car. I wonder if this cause so much heat or not with the new model. actually, that usage is not an issue to be solved by software since,cpu clock speed does not cause the only heat.

                                      Ramsey, 27 Sep 2023This is all wrong. TSMC's 3nm is not significative... moreThermal conductivity or SoC issues are one thing, Apple ignoring the need for better cooling is another story, that has been seen before in the M2 Macbooks. It is mindboggling how they repeat the same mistakes they did before again and I bet, they will blame it on others just as they did with Intel back in the days.

Apple is not cooling the chip properly which JerryRigsEverything has shown and Apple has done the same shit with the M2 Macbooks, which also went above 100°C which is unacceptable.
