Apple Says iPhone 15 Pro Overheating Due to iOS 17 Bug, Not Hardware Design

Widespread complaints about the overheating of the new iPhone 15 Pro and Pro Max have been addressed by Apple, who attributed the issue to a software bug in iOS 17. According to the company, the titanium frame and aluminum substructure of the new phones do not contribute to the problem, and they actually dissipate heat better than previous Pro models that used stainless steel.

Users began sharing stories about their new iPhones overheating or feeling excessively hot shortly after the release of the iPhone 15 series. Some reported not being able to comfortably hold their phones, while others shared pictures of infrared thermometers showing temperatures exceeding 80 degrees Fahrenheit.

During a review of the iPhone 15 Pro and Pro Max, the author did not encounter any overheating issues. However, the 15 Pro Max did become noticeably hot while using a 140W power adapter to charge it, as well as after playing the game Resident Evil Village for 30 minutes.

In response to the complaints, Apple explained that there are a few conditions that can cause the iPhone to run warmer than expected. First, the device may feel warmer during the initial days of setting up or restoring due to increased background activity. There is also a bug in iOS 17 that is impacting some users and will be addressed in a software update. Additionally, recent updates to certain third-party apps are overloading the system, and Apple is working with these app developers to roll out fixes.

A video by tech reviewer Faruk Korkmaz showed his iPhone 15 Pro Max’s temperature reaching 98 degrees within minutes of opening the Instagram app. The same issue occurred on his iPhone 14 Pro Max running iOS 17. Apple explained that recent updates to certain third-party apps, including Instagram, Asphalt 9, and Uber, overload the phone’s CPU, causing it to get warmer. Instagram has since released an updated version of its app.

Apple has not provided a specific release date for the software update that addresses the iOS 17 bug but assured users that the fix will not reduce the iPhone’s performance.

Regarding charging, Apple stated that the 15 Pro and Pro Max support any USB-C adapter compliant with the USB-C standard, including USB Power Delivery. The iPhone regulates itself to cap charging at a maximum of 27W. If a 20W or higher charger is used, the phone may temporarily become warmer. Some users have reported the iPhone 15 Pro and Pro Max getting uncomfortably hot while charging.

Apple’s support page acknowledges that new iPhones may feel warm during initial setup, restoration, or wireless charging, which has been observed with previous iPhone models and Android phones as well.

Until Apple releases the iOS 17 update, users experiencing overheating can try a few steps. Turning on Low Power Mode can help kill background tasks, limit the display’s refresh rate to 60Hz, and reduce brightness. It is also advisable to avoid exposing the phone to direct sunlight or extremely hot environments for prolonged periods. If a specific app is suspected to be causing the issue, disabling background refresh for that app under the Settings app’s General section may help.

In conclusion, Apple has acknowledged the complaints about overheating in the new iPhone 15 Pro and Pro Max and attributed them to a software bug in iOS 17. The company is working on a software update to address the issue and is collaborating with third-party app developers to implement fixes. Until the update is released, users can follow a few steps to mitigate overheating.
