A lot of users who upgraded to iPhone 15 from previous iPhone models were quick to realize that their iPhone 15 is different than their previous one. Users have noticed that their new iPhone 15 is overheating abnormally even when it is not in use. Some even say the iPhone becomes really hot, making it very uncomfortable to touch or use.
It is normal for your iPhone to get warm when it is being charged or in use. But it is never supposed to get hot. It also appears that the issue mainly impacts the higher-end and pricier variants – the iPhone 15 Pro and iPhone 15 Pro Max.
Why iPhone 15 gets hot
Ming-Chi Kuo previously said that the problem of overheating probably stems from the “compromises” made by Apple in the thermal system design to achieve a lightweight build. These compromises, as per Kuo’s analysis, involve a “reduced heat dissipation area” and the introduction of a new titanium frame, resulting in diminished thermal efficiency.
