iPhone 15 Pro Max Overheating Issue

The iPhone 15, Apple’s latest flagship, has been the talk of the tech world. However, not all the chatter has been positive. A significant number of users have reported overheating issues, especially with the Pro models.

So does the iPhone 15 still have an overheating issue? The answer (according to Apple) is No! Once Apple acknowledged the issue they claimed it was software related (not hardware) and that the issue has been resolved with an update to iOS version 17.0.3.

This article delves deep into the matter, drawing insights from various trusted sources to give you a comprehensive understanding of the issue.

The Overheating Saga

Initial Reports

Soon after the iPhone 15’s release, users started reporting overheating issues. The Guardian highlighted that many Pro and Pro Max users complained about their devices getting extremely hot, even during basic tasks like web browsing. Similarly, ZDNet’s Jason Hiner experienced overheating while reviewing the iPhone 15 Pro and Pro Max, particularly when charging or using certain apps.

Apple’s Response

Apple was quick to respond to these complaints. Initially, the company suggested that the overheating could be due to excessive activity when setting up a new iPhone, issues with recently updated apps, or a bug within iOS 17. However, as the complaints grew, Apple acknowledged a software issue in iOS 17 causing the iPhone 15 models to run at abnormally high temperatures.

The iOS 17.0.3 Update

Apple released the iOS 17.0.3 update to address the overheating issues. According to Macworld, real-world tests showed that the update dramatically lowered temperatures. ZDNet’s testing revealed that the update could reduce temperatures by as much as 15 degrees at its hottest moment.

However, there were concerns. 9to5Mac posed a critical question: Did the iOS 17.0.3 update compromise the performance of the iPhone 15 Pro to prevent overheating? Their preliminary tests using Geekbench 5 indicated that the update most likely didn’t affect the iPhone 15 Pro’s performance.

Other Contributing Factors

While the iOS update aimed to resolve the overheating issues, other factors might contribute to the problem. MacPaw suggests that external factors, such as the environment and how the phone is used, can cause overheating. For instance, using the iPhone in direct sunlight or running intensive apps for extended periods can lead to increased temperatures.

Community Feedback

The Apple community, always vocal about their experiences, took to forums to discuss the issue. On Apple’s discussion threads, many users shared their personal experiences, with some noting improvements after the iOS 17.0.3 update, while others still faced challenges.


The iPhone 15 overheating issue has been a significant concern for users and Apple alike. While the iOS 17.0.3 update seems to have addressed the problem for many, it’s essential to consider other factors that might cause your device to overheat. As always, keeping your software updated and being mindful of external conditions can go a long way in ensuring your iPhone runs smoothly.
