Well-known Apple industry chain analyst Ming-Chi Kuo of Tianfeng Securities said that complaints about the iPhone 15 Pro model’s heating issues have nothing to do with the 3-nanometer node used by TSMC’s A17 Pro chip. Ming-Chi Kuo said the overheating could be caused by "compromises in the cooling system design" that allowed Apple to reduce the weight of the iPhone 15 Pro models.

He also said that the reduction in heat dissipation area and the titanium frame had a negative impact on the device's thermal efficiency. Apple is expected to address the thermal issues with a software update, but unless Apple plans to reduce processor performance, improvements will be limited.
Ming-Chi Kuo believes that if Apple cannot "properly solve this problem," iPhone 15 Pro shipments may be affected throughout its life cycle.
There are reports that iPhone 15 Pro models can become very hot to the touch, and some tests show that when this happens, the processor throttles to cool the iPhone. These tests are conducted under benchmark tests and extreme usage conditions and may not affect users' daily lives, but the cooling performance of the iPhone 15 Pro models when running console-quality games such as "Resident Evil" and "Death Stranding" remains to be seen.
