It wouldn’t be a proper iPhone launch without a bit of controversy, and this year there have been numerous reports of iPhone 15 Pro series models overheating. Apple has now acknowledged the issue and is actively working on a fix with an upcoming software update.
We’ve identified some conditions that can cause your iPhone to run hotter than expected. Your device may feel warmer during the first few days after setup or reset due to increased background activity.
We’ve also discovered a bug in iOS 17 that is affecting some users and will be fixed in a software update. Another issue involves some recent third-party app updates causing system overload. We are working with these app developers on fixes that are being rolled out. – Apple representative
The most likely suspects attributing the overheating and throttling issues according to some analysts are thermal design compromises that have led to a smaller heat dissipation area for the new Pro models. The new titanium frames also have a lower thermal conductivity higher than stainless steel, which could be another key factor.

We should mention that we couldn’t exactly replicate the overheating issue in our iPhone 15 Pro Max review where we used two units of the same device. However, we noticed significant GPU throttling under load. We’ll be sure to follow up on the iPhone 15 Pro series overheating controversy and update you accordingly.
