For Apple, the iPhone 15 is exposing more and more problems, such as the body heating up too much. Ian Zelbo, author of the technology media 9to5Mac, said on the social platform

Zelbo noted that the heating problem is most severe when his iPhone is fast-charging from 25% to 60%. When the battery level exceeds 70%, the temperature of the phone drops significantly. It's still hot, but not hot to hold in your hand.
AndroidAuthority author Aamir Siddiqui said: "The heating area is on the right side of the phone, near the bottom of the camera. I am not playing games, not charging, and not using WiFi, so it is inexplicably hot."
An up owner at Bilibili tried out the game "Genshin Impact" with an iPhone 15 Pro. At a room temperature of 26.5 degrees Celsius, after 30 minutes of game time, the body temperature had soared to 49 degrees Celsius, and frame drops were visible to the naked eye.
Some user tests have found that the temperature of the iPhone 15 reaches as high as 46.7 degrees Celsius during gaming. There are many opinions on the heating of the iPhone 15 series. Some people say it is still a problem with Apple’s internal design, while others say it is a matter of the 3nm process.
However, Ming-Chi Kuo said that the overheating problem of the iPhone 15 Pro series has nothing to do with TSMC's 3nm process. It is likely that in order to make the weight lighter, compromises were made on the heat dissipation system design. The new machine has a smaller heat dissipation area, and the use of titanium alloy affects the heat dissipation effect.
Ming-Chi Kuo predicts that Apple will correct this problem through software updates, but unless the processor performance is reduced, the improvement may be limited. If Apple does not properly solve this problem, it may be detrimental to the shipments of the iPhone 15 Pro series product cycle.
