After publishing my thermal images of the iPhone 15 Pro before and after updating to iOS 17.0.3 -- which has resolved the overheating issue when fast-charging -- I have received reports from iPhone 15 Pro users who are still having problems with their phones getting too hot, even after updating to iOS 17.0.3.

None of the reports have involved overheating during fast-charging, so that issue does still appear to be fixed. However, people have reported problems with their iPhone 15 Pro or Pro Max overheating when making phone calls, playing games, keeping their phone in their pocket, playing music, using the camera. 

Reports: Overheating continues after iOS 17.0.3

These reports have come through social media, so it's not possible to fully verify all of them. However, one of them comes from a former colleague I trust and the most severe report came from a source I was able to follow up with who did provide convincing evidence of their overheating issue. 

On the left, you can see the screen burn-in issue on this iPhone 15 Pro Max from the wallpaper image on the right.

That's Gabriel Suchowolski, a graphic designer in Madrid, Spain, who bought an iPhone 15 Pro Max. He upgraded from an iPhone 13 Pro, which he reported only ever got a little warm when he was on a very long phone call or playing a graphics-heavy game. After getting the iPhone 15 Pro Max, he said it would get hot -- "not hot that burns, but hot like toast ... in the area to the right of the [camera] lenses and on the side near the volume buttons." He said this happened specifically when making phone calls longer than a minute and when taking 4-5 photos or more in a row. And it continued to happen consistently even after he updated his phone to iOS 17.0.3.

Suchowolski provided a photo of a thermometer he used to measure the temperature of his iPhone 15 Pro Max when it was overheating. The thermometer clocked the temperature at 42 degrees Celsius. That's 107.6 degrees Fahrenheit -- very similar to the 107.1 F reading I got during my testing of the phone when fast-charging, before iOS 17.0.3. 

In addition to overheating, Suchowolski also experienced some odd screen burn-in, as shown in the photo on the right (similar to an issue reported by a Twitter user). The combination of these two problems could mean that this particular phone has quality control issues. Suchowolski has AppleCare+ on his iPhone 15 Pro Max and has an appointment at an Apple Store to give Apple Support a chance to look at the device and rectify the situation.
