Apple has acknowledged a concern that has been observed by many buyers in the past week: the iPhone 15 and 15 Pro can become uncomfortably warm. Reported over the weekend that the company stated the issue is being caused by background activity, a bug in iOS 17, and certain third-party apps.
Apple has assured users that a software update is on the way, along with fixes from app developers.
A spokesperson issued a statement, saying, “We have identified a few situations that can lead to the iPhone running warmer than anticipated. During the initial days after setup or restoration, increased background activity may cause the device to feel warmer. We have also detected a bug in iOS 17 affecting some users, which will be resolved through a forthcoming software update.
Additionally, recent updates to certain third-party apps have been overloading the system, and we are collaborating with these app developers to implement solutions, which are currently in the process of being deployed.”

iPhone 15 Overheating Issue and App Affectedness
The affected applications include Uber, Instagram, and Asphalt 9. Meta has already issued a solution for Instagram, so it’s advisable to ensure you have the latest version installed.
It’s important to note that the overheating problem might be specific to certain app combinations and usage scenarios, as not all users have reported experiencing it. (For reference, Engadget did not encounter these issues during their device review.)
It’s worth mentioning that the titanium frame of the iPhone is not responsible for this problem. Apple clarified to MacRumors that the design, in fact, enhances heat dissipation compared to previous models featuring stainless steel frames.
The company also emphasized that the issue is not directly linked to its A17 Pro chip and that the forthcoming fix will not compromise performance in any way.
Additionally, this issue has no connection to high-power chargers, as the iPhone 15 fully complies with USB-C PD standards and includes built-in safeguards to prevent overheating damage. So, if you’ve been affected by this problem, please remain patient as a solution should be coming soon.
Conclusion
Apple has acknowledged the overheating issue in the iPhone 15 and 15 Pro, attributing it to background activity, an iOS 17 bug, and certain third-party apps. They are actively working on a software update and collaborating with app developers for fixes.
This problem doesn’t relate to the phone’s frame or its A17 Pro chip and is unrelated to high-power chargers. Users affected by this issue should expect a solution soon.
