Title: iPhone 15 Pro Series Overheating Issues Linked to Thermal Design Compromises


The iPhone 15 Pro series has taken the smartphone market by storm, but recently, reports regarding overheating issues have surfaced. Users have been complaining about the devices running hot since their initial release. However, a recent note by renowned analyst Ming-Chi Kuo suggests that the overheating problem is not directly related to the A17 Pro chipset but rather due to compromises made in Apple’s thermal system design. This article delves into the details of Kuo’s analysis and its implications for iPhone users.

The Culprit: Thermal Design Compromises:

Contrary to initial beliefs that the A17 Pro chipset was responsible for the overheating, Kuo’s assessment reveals that the blame lies with Apple’s design choices. In an attempt to make the iPhone 15 Pro models lighter, Apple had to reduce the heat dissipation area. Additionally, the use of titanium, which has higher heat conductivity, aggravated the heat management issue for the new chipset. These compromises in the thermal design appear to be the root cause of the overheating problem.

Software Update to Address Throttling:

To mitigate the overheating issues, Apple is expected to release a software update. While this update can manage the problem, it will not completely resolve it. The only way to truly prevent the phones from overheating would be to limit their performance and power requirements through the software, thereby generating less heat. This compromise between performance and heat management poses a challenge for Apple, as users expect high-performance devices without compromising on their sleek design.

Inconsistent Overheating Reports:

One aspect that remains puzzling is why only a portion of the iPhone 15 Pro series phones are affected by overheating. While the theory proposed by Kuo sheds light on the design-related concerns, it does not provide a definitive explanation for the inconsistent reports. Some users have reported no overheating issues on their devices, while others are experiencing significant problems. This discrepancy raises questions about possible variations in cooling pad materials used in different batches of the phones. Further investigation is necessary to determine the exact cause of this inconsistency.


The iPhone 15 Pro series has faced criticism for its overheating issues, which have now been attributed to design compromises in Apple’s thermal system. Contrary to initial assumptions, the A17 Pro chipset is not directly responsible for the overheating. Apple’s attempts to make the devices lighter by reducing the heat dissipation area, coupled with the use of titanium, have resulted in erratic heat management. While Apple is expected to release a software update to mitigate the problem, it is unlikely to completely resolve the overheating. Addressing this issue while maintaining optimal performance and a sleek design remains a challenge for the tech giant. As more information emerges, users and enthusiasts eagerly await a definitive solution to the iPhone 15 Pro series overheating problem.
