Complaints about heat issues with the iPhone 15 Pro models are not related to TSMC's 3-nanometer node that was used for the A17 Pro chip, according to well-respected Apple analyst Ming-Chi Kuo.

Kuo says that overheating could be caused by "compromises made in the thermal system design" that allowed Apple to cut down on the weight of the ‌iPhone 15 Pro‌ models. Kuo says that the reduced heat dissipation area and titanium frame have negatively impacted the thermal efficiency of the devices.

Apple is expected to address the thermal issues through software updates, but improvements will be limited unless Apple plans to lower processor performance. Kuo believes that if Apple is unable to "properly address this issue," shipments could be impacted over the life cycle of the ‌iPhone 15 Pro‌.

There have been reports about the ‌iPhone 15 Pro‌ models becoming hot to the touch, and some tests have suggested that when this happens, the processor is throttled in order to cool the iPhone down. These tests have been benchmarks and extreme use cases that may not impact users in day-to-day life, but it remains to be seen how the ‌iPhone 15 Pro‌ models will run console-quality games like Resident Evil Village and Death Stranding.

Apple made the iPhone 15 series official earlier this month and as always, the Pro models bring more to the table than their non-Pro siblings. For one, the iPhone 15 Pro and 15 Pro Max feature a new Titanium build that makes them lighter. However, an analyst suggests Apple may have sacrificed the cooling system to achieve this weight reduction in the Pro series.

For the unaware, there have been widespread reports of heating problems on the iPhone 15 Pro models. Some users claimed their phones get too hot to even hold without a case. Various reports concluded, including this investigation from Android Authority, that the heating is likely caused due to the new A17 Pro chip.

50C dam, that heat will going to kill the battery very fast.

This is why you don't rush to buy the new product on the 1st day release.
No, according to iPhone owners this is a seasonal feature.

It's also consumerism.

Apple has acknowledged complaints from iPhone 15 Pro and iPhone 15 Pro Max users about the devices running hotter than expected. In a statement, the company said a software update is coming soon to address the overheating issue.

The problems appear to stem from bugs in iOS 17 and recent updates to some third-party apps, including Instagram and Uber, that overload the A17 Pro chip. Apple said it is working directly with app developers like Instagram to roll out fixes.

Apple analyst Ming-Chi Kuo, on the other hand, argues that Apple is compromising on cooling in its quest for a lighter iPhone 15 Pro. Also, some reports had speculated that the new titanium frame design of the iPhone 15 Pro could contribute to overheating. However, Apple claims the new materials allow for better heat dissipation than previous stainless steel iPhones.
