According to reports, many iPhone users have recently complained that their newly purchased iPhone 15 and iPhone 15 Pro Max phones are overheating and cannot even be used without a phone case. Some users said that the temperature of their iPhone 15 can reach as high as 47 degrees Celsius. Some users even said that without using a phone case, the phone was too hot to touch with their hands.

Zelbo also said: "I thought people were exaggerating, but no. It really doesn't perform well. I also found that when holding it in my hand, the left edge and back are the hottest spots."
In 2017, Apple launched a fast charging feature for the first time on iPhone 8, allowing users to get up to 50% power in about 30 minutes. With the release of the iPhone 15 series of mobile phones earlier this month, Apple has switched from a proprietary charging interface to a standardized USB-C charging interface in order to meet new EU regulations.
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.
Apple has yet to comment.
Some other iPhone 15 users have said they feel overheating while playing games or scrolling through apps.
Technology media AndroidAuthority reported that overheating problems can occur when using the phone for a long time, such as switching between chat applications and social media videos.
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."
A test found that the temperature of the iPhone 15 reached as high as 46.7 degrees Celsius during gaming.
Well-known Apple product analyst Ming-Chi Kuo said earlier today that the overheating problem of the iPhone 15 series has nothing to do with TSMC's 3-nanometer process. It is likely that the design of the cooling system was compromised in order to reduce the weight of the phone. For example, the heat dissipation area becomes smaller, or the titanium alloy frame affects the heat dissipation effect.
Ming-Chi Kuo also said that Apple is expected to fix this problem by updating the system. But unless processor performance is reduced, the improvement may be limited. If Apple cannot properly solve the problem, it will be detrimental to iPhone 15 shipments.
The overheating problem of iPhone 15 this time coincided with the iPhone 12 model being exposed to excessive radiation.
In the middle of this month, the French National Spectrum Administration (ANFR) said that tests found that the electromagnetic radiation value of Apple's iPhone 12 mobile phone exceeded the allowable range, and it had asked Apple to stop selling this mobile phone in France. In addition, regulatory authorities in Germany, Belgium, the Netherlands and Italy are also paying close attention to the matter.
