Troubleshooting iPhone 15 Overheating Issues: iOS 17 Bug and Third-Party Apps to Blame

iPhone 15 Overheating Issues: Causes and Solutions

Discover the reasons behind the overheating problems with the new iPhone 15 Pro and Pro Max. Learn about the iOS 17 bug and third-party app issues causing excessive heat.

The release of the iPhone 15 Pro and Pro Max has been marred by widespread complaints of overheating. Apple has acknowledged the problem and attributed it to a software bug in iOS 17, as well as issues with certain third-party apps. In this article, we delve into the causes of the overheating and explore the steps being taken to address the issue.

Causes of Overheating

Contrary to initial speculation, Apple clarifies that the titanium frame and aluminum substructure of the new iPhones do not contribute to the overheating problem. In fact, these materials are designed to dissipate heat more effectively than previous stainless steel models. However, certain conditions have been identified that can lead to the device running warmer than expected.

  1. Increased Background Activity: During the initial setup or device restoration, the iPhone may exhibit higher heat levels due to heightened background activity. This should normalize after a few days.
  2. iOS 17 Bug: Apple acknowledges a bug in iOS 17 that is affecting some users and causing overheating. The company assures users that a software update will be released to address this issue.
  3. Third-Party App Issues: Recent updates to certain third-party apps, such as Instagram, Asphalt 9, and Uber, have been found to overload the phone's A17 Pro chip's CPU, resulting in excessive heat. Apple is working closely with these developers to implement fixes, and Instagram has already released an updated version of their app.

Solutions and Future Updates

While an exact timeline for the software update addressing the iOS 17 bug has not been provided, Apple assures users that the fix will not compromise the iPhone's performance. Additionally, the company advises that the iPhone 15 Pro and Pro Max support USB-C adapters compliant with the USB-C standard, including USB Power Delivery. However, using a charger with a wattage of 20W or higher may temporarily increase device temperature during charging.


Apple is actively working to resolve the overheating issues reported with the iPhone 15 Pro and Pro Max. Users experiencing excessive heat are encouraged to monitor for software updates and ensure their third-party apps are up to date. By addressing the iOS 17 bug and collaborating with app developers, Apple aims to provide a smoother and cooler user experience with its latest flagship devices.
