During the recent release of the iPhone 15, there was a lot of buzz and enthusiasm. However, a few initial purchasers took to social media to express their dissatisfaction with overheating devices, causing discomfort and impacting performance. While many attributed this issue to the A17 Pro processor, a recent report suggests this may not be the true cause.
Per analyst Ming-Chi Kuo, the iPhone 15 Pro’s problems with overheating are not connected to TSMC’s advanced 3nm node, the new technology utilized by Apple for the A17 Pro processor. Kuo clarifies that the issue is more likely due to “the sacrifices made in the thermal system design to achieve a lighter weight, such as reducing the heat dissipation area and incorporating a titanium frame, both of which can negatively affect thermal efficiency.”
The weight of the iPhone 15 Pro models has significantly decreased, with the Pro Max shedding around 20 grams and feeling noticeably lighter compared to the iPhone 14 Pro Max. However, Apple also made changes to the internal components which seem to have impacted the chip’s cooling process.
According to Kuo, Apple plans to resolve the problem of overheating through a software update. However, he warns that the improvements may not be significant unless Apple reduces the performance of the processor. It may take a few weeks for this update to be released, as iOS 17.1 is not yet in the beta testing phase.
During our evaluation, we also noticed that our iPhone 15 Pro Max tends to get too hot while charging. This seems to be a common problem among those who have recently acquired the device. The iPhone 15 is the first model to feature a USB-C charging and data port, after using the Lightning port for the past decade. Kuo does not mention if Apple is looking into this specific problem.
