There’s been widespread reports from users saying the iPhone 15 Pro, which was released on September 22, has been overheating — in some cases, to the point where a customer feels the phone’s too hot to even hold.
It’s not clear how widespread the issue may be, and Apple hasn’t publicly commented yet on the reports.
The Wall Street Journal conducted its own tests and found that their iPhone 15 Pro Max reached 106 degrees Fahrenheit while charging, and 112 degrees when charging and doing other intensive tasks. The publication also published a video showing its thermal tests on the phone. Apple declined to comment to the Journal about their findings.
Some iPhone 15 Pro owners have taken to social media sites in the US and China to complain about the issue.
One Twitter user posted a video of themselves taking a temperature reading of the back of their iPhone 15 — it hit 42 degrees Celsius, or about 108 degrees Fahrenheit, according to the video.

In a discussion forum on Apple’s website, one user complained that their iPhone 15 Pro got hot enough that it was uncomfortable to hold after just 10 minutes streaming videos over wifi with the screen at 30% brightness, noting that the battery also dropped by 15% in the same period of time.
Bloomberg reported that Apple tech support agents have been fielding complaints about iPhone 15 Pro models getting too hot and directing customers to an old support page about what to do if your iPhone or iPad gets too hot or too cold.
The iPhone 15 Pro model is notably the first smartphone made by Apple with a titanium enclosure.
Ming-Chi Kuo, a prominent Apple analyst, said in a Medium post that he believes any overheating issues are primarily caused by “compromises made in the thermal system design to achieve a lighter weight” related to the titanium frame.
In other words, the titanium casing may make it more difficult for heat to dissipate from the phone, causing overheating.
But the cause and extent of any overheating problems isn’t clear at the moment, and it’s important to note that the issue doesn’t appear to be impacting everyone who owns an iPhone 15 Pro.
