IPhone 15 Pro Overheating Is A Thermal Design Issue

     The iPhone 15 series has been on the market for some time now, and users have also discovered some issues after widespread use, such as fever. From a large amount of feedback, it can be seen that the current iPhone 15 Pro has a very obvious heat generation, making it the hottest model in the past three generations.
    The overheating issue of the iPhone 15 Pro series is not related to TSMC's 3nm process. It is likely that the main reason is to make the weight lighter, so compromise has been made to the design of the cooling system, such as reducing the heat dissipation area and using titanium alloy to affect the cooling effect. It is expected that Apple will fix this issue by updating the system, but unless the processor performance is reduced, the improvement effect may be limited.
