Days after the iPhone 15 Pro and 15 Pro Max went on sale, complaints surfaced from owners saying the devices had overheating issues. The issue appears randomly with what it says happens when taking pictures, charging the device and also happens when the device is just being used to read web pages.
Ming-Chi Kuo, a leading analyst of what's going on at Apple now says the issue is not caused by the A17 Pro chip as people think. Instead it is due to Apple's decision to use a titanium frame and the cooling system is not very good at dispersing heat to keep the device thin and light. According to him, Apple will release a software update later to solve this issue which may reduce the performance of the chip.
Apple has not yet issued any official statement regarding this heating issue. In various benchmark tests it can be seen that the performance of the A17 Pro plummeted after the second test was performed due to heating issues. On the Galaxy S23 Ultra with Snapdragon 8 Gen 2, benchmark scores drop off steeply but are consistently higher than the 15 Pro Max. This is because the Galaxy S23 Ultra is equipped with a large cooling chamber.
Although this heating issue is reported by many users. We ourselves did not encounter any overheating issues on the 15 Pro Max that we purchased. The heating when charging is the same as the temperature on the 14 Pro Max which is charged using a 30W charger.
