It has been pointed out that ``iPhone 15 Pro's abnormal heat generation'' is caused by ``a design compromise,'' not the A17 Pro.

Multiple users of the iPhone 15 series have reported that the device becomes abnormally hot while charging or when used for long periods of time . Some people have suggested that the cause of the abnormal heat generation may be the SoC 'A17 Pro' installed in the iPhone 15 Pro, but Ming-Chi Kuo, an analyst who handles highly accurate leak information related to Apple, said, , pointed out that 'the cause was a design compromise.'

There have been reports of an issue with the iPhone 15 series in which the device itself generates abnormal heat during rapid charging or when used for long periods of time. Symptoms seem to vary depending on the user, but the most common one is that the device generates so much heat that it cannot be held with bare hands during rapid charging. When we measured the temperature using a thermography camera, it seems that the temperature of the main body exceeds 45 degrees when abnormal heat is generated.

Regarding the cause of this heat generation, technology media PhoneArena said, ``We found that the iPhone 15 Pro and iPhone 15 Pro Max become abnormally hot, but this is due to Apple's low standards for the A17 Pro installed SoC. This may be the cause.''

However, Kuo updated his blog and said, 'According to my research, the overheating issue of the iPhone 15 Pro series has nothing to do with TSMC's advanced 3nm process, which is responsible for manufacturing the A17 Pro. The cause of the heat generation is titanium. This is because in order to achieve weight reduction by adopting a frame, a compromise was made in the thermal design, reducing the heat dissipation area and worsening thermal efficiency.

However, Apple is expected to address the abnormal heating issue through a software update, and Kuo noted that unless Apple reduces processor performance, ``improvements may be limited.'' Regarding this, Apple-related media 9to5Mac points out, ``It may be difficult to make many improvements without compromising processor performance.''

Kuo said, ``If Apple does not properly address this issue, it may have a negative impact on shipments throughout the product life cycle of the iPhone 15 Pro series,'' Kuo said, adding that the heating issue could affect sales of the iPhone 15 Pro. I pointed out the gender.
