iPhone 15 overheats, it seems all models in the line. Measurements taken with an infrared camera show temperatures of up to 46.7 degrees Celsius on the case. Renowned tech industry analyst Ming-Chi Kuo attributes these problems to “constructive trade-offs.”
The problem is widespread and does not have a clear scenario, some users complain that their iPhone 15 or iPhone 15 Pro “burns” during wired charging, others – during normal use, even without complex tasks, reports 9to5Mac (1, 2).
Some tinkering with new hardware and software is acceptable; the iPhone traditionally gets hot and uses up battery power too quickly in the first 24 hours after unboxing, but this is still too much.
According to Kuo, the reason is not the new A17 chip in the iPhone 15 Pro (because the “regular” iPhone 15 doesn’t have it), but rather compromises in the cooling system. TSMC’s 3nm process has nothing to do with it. In particular, to reduce mass, the area for heat dissipation was reduced. However, according to the analyst, Apple will solve this through a software update, but there may be an option in which Apple will have to reduce the processor performance.
