Owners of the recently released iPhone 15 Pro have Roland Prestontaken to social media to complain about the premium version of Apple's flagship product overheating.

On the forum, one post complaining about the overheating received 2,215 "me too," responses.

Ian Zelbo, a reporter at the Apple news site 9to5Mac, posted on X, formerly Twitter, that, "My iPhone 15 Pro Max is almost too hot to touch while fast charging right now."

Internet, WSJ test iPhone 15 heat

The Wall Street Journal's Joanna Stern conducted tests on the iPhone 15 Pro Max and found that the phone would hit 112 degrees during a high use test, though the Journal noted that an iPhone 14 Pro Max model would hit similar temperatures during the same test. The Journal also noted that the phone would remain at regular temperatures during standard use.

YouTube technology channel Bulls lab tested the phone during intense use and found that a portion of the back side of the phone reached over 116 degrees Fahrenheit (46.7 degrees Celsius).

Fellow YouTube channel iAuthority also tested an iPhone 15 Pro model and registered that the case hit over 98 degrees Fahrenheit (36.8 degrees Celsius).

Tech industry analyst Ming-Chi Kuo pointed to design changes as possible causes for the problem.

"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," an analyst for TFI Securities wrote in a Medium post.

USA Today has reached out to Apple for comment and a company representative directed a response to a support page on how to handle a device that gets too hot.
