Kuo: iPhone 15 Pro Overheating Issues Likely Due to Thermal Compromises, Not 3nm Node
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.
