With several initial users complaining that their iPhone 15 Pro models are overheating, famed Apple analyst Ming-Chi Kuo of TF International Securities has come up with the reason, in a note. Kuo has mentioned that Apple’s A17 Pro chip is not to be blamed for overheating issue in the iPhone 15 Pro and Pro Max models but it is likely the “Apple’ compromises” in the design of the thermal system that is causing the models to overheat.
Several reports are doing the rounds about the iPhone 15 overheating, and some say it is across the vanilla iPhone 15 and iPhone 15 Plus models too Measurements taken with an infrared camera have shown temperatures touching 116F, says a recent report by 9to5Mac. The issue appears to be with design of the thermal system and not the A17 Pro chip which is built on TSMC’s advanced new 3nm node. The chip seems to release more heat than the device can dissipate.
“The iPhone 15 Pro series overheating issues are unrelated to TSMC’s advanced 3nm node / iPhone 15 Pro系列的過熱問題，與台積電的3nm製程無關,” Kuo posted on X, formerly Twitter.

According to Kuo, the primary cause of heating is more likely the compromises made in the thermal system design to achieve a lighter weight, such as the reduced heat dissipation area and the use of a titanium frame, which negatively impacts thermal efficiency.
The Apple analyst further added that if the iPhone maker does not” properly address this issue”, it could negatively impact device shipments over the product life cycle of the iPhone 15 Pro models.
It should be noted that Kuo had previously said that the iPhone 15 Pro Max is garnering the most attention from prospective buyers and it has bedimmed last year’s iPhone 14 Pro Max’s demand. The Cupertino-based tech giant also needs to address production delays which is said to result in longer shipping times.
