The release of the new iPhone 15 models did not seem to be a trouble-free experience for Apple. In addition to the fact that titanium cases are still not as hard to scratch as it seemed before, there have also been complaints about smartphones overheating. And this is found in both iPhone 15 models, as well as in the iPhone 15 Pro and 15 Pro Max.

For example, during wired charging, the iPhone 15 Pro Max can get so hot that it is difficult to hold it in your hands. Toward the final stage of charging, the device did reduce the temperature, although it was still hot.

Also, prolonged use could lead to noticeable heating, even though the smartphone was not performing any heavy tasks at the time.

Ming-Chi Kuo briefly commented on this situation in his blog. According to the analyst, this is not related to, for example, the new 3-nanometer A17 Pro chips manufactured by TSMC. According to him, the problem is more likely to be related to compromises in the design of the thermal system:

The primary cause is more likely the compromises made in the thermal system design to achieve a lighter weight, such as the reduced heat dissipation area and the use of a titanium frame, which negatively impacts thermal efficiency.

The analyst noted that a solution to this problem can theoretically be achieved through software. However, it can also affect the overall performance of devices.

It’s expected that Apple will address this through software updates, but improvements may be limited unless Apple lowers processor performance.

Kuo also added that this situation could affect the sales of the entire new line of Apple smartphones if the problem is not fixed properly. And it is hard to disagree with him.
