iPhone 15 Pro has an overheating problem
According to many, the imperfectly designed A17 Pro chip is to blame
However, a well-known analyst “places the blame” on titanium
It’s starting to look like the first case hit the new iPhone 15 just a few days after the start of sales. It refers to heating, according to many, rather overheating, which appears in not quite expected situations, when the iPhone does not exert extreme power to launch a game or another relatively demanding operation. Let’s take a closer look at the whole heating problem.
iPhone 15 Pro and the case of overheating
Early users began to notice that the iPhone 15 Pro (Max) heats up more than last generation during relatively common tasks. It can be, for example, more demanding multitasking (several running applications, video/music in the background, connection to Bluetooth headphones), uploading video to social networks, but also charging or playing games, which Apple extends extensively with the iPhone 15 Pro and Pro Max.
In addition to the fact that the new iPhone 15 is noticeably warmer, as demonstrated on the X network by colleague Vojta Dalekorej (Wrtech). He shared footage from the thermal camera, so the heating also limits some functions of the iPhone. Several sources agree that the backlight of the display drops to about half during higher heating and it is not possible to manually increase it again. A YouTuber was one of the first to point out this problem iPhonedo.
I did a quick comparison #iPhone14ProMax a #iPhone15ProMaxto look at the alleged overheating.
I still have a few more tests to do, but this is what I’m interested in so far:
– iP15 heats up significantly faster (first video, accelerated – iP15 always at the top, iP14 at the bottom even in photos)

According to other sources, as well as our editorial measurement, this phenomenon with reduced screen brightness can also occur when editing videos or photos for publishing on social networks. So it started to be said that poorly optimized applications such as Instagram, TikTok and others are to blame for the overheating problem.
The environment in which the iPhone is located does not play a big role either – you yourself will admit that at an outdoor temperature of 23-28 °C, similar performance concessions should not occur for such a powerful machine as the new iPhone 15 Pro.
Is the A17 Pro chipset to blame?
The consensus among affected users is that Apple’s new A17 Pro chipset is responsible for overheating. This is the first 3nm chipset in a smartphone and it is also the first chipset of this architecture produced by TSMC. According to many, from a technological point of view, the chipset is imperfect precisely in terms of working with heat.
The Internet is filled with smiling pictures of iPhones with MagSafe coolers
“TSMC didn’t have a good enough yield of 3nm chips, so they had to lower their performance standards to accommodate more A17 Pro chips. […] Apple then pushed the watts as high as possible to still show a decent improvement in the marketing benchmarks.
However, the high consumption leads to a lower battery life than we expected with 3nm chips. It also leads to more thermal throttling than we expected,” wrote on X Vadim Jurjevwhich works with YouTube channel Max Tech.
Or perhaps titanium?
However, several sources rely on the fact that titanium – as the main material of the chassis of this year’s iPhones – prevents excess heat from passing through better. The fact is that titanium is a very good thermal insulator. One of the most vocal supporters of the theory about the problematic titanium is also a well-known analyst Ming-Chi Kuo.
“My research suggests that the iPhone 15 Pro overheating issues are not related to TSMC’s advanced 3nm chip technology. Rather, the main cause is compromises in the design of the heat dissipation system that were made in order to achieve lower weight, such as a reduced surface area for heat dissipation and the use of a titanium frame, which negatively affects thermal efficiency.” he wrote in his commentary on the case.
Don’t overlook
Hell for the eyes: this is what the first broken iPhone 15 Pro looks like
But the solution will probably be simpler than it seems. The important thing is that it is not a fatal problem that could cause damage to the device in the short term. Apple will probably come out with a fix update soon (maybe already 17.0.3) which will reduce the performance slightly and the overheating during normal use will be solved in one fell swoop.
The question is, how will it be with playing “console” games like Resident Evil or Assassin’s Creed, which Apple boasted about during the presentation event. We’ll have to wait at least until the release of these games for an answer.
