Apple has just unveiled the latest incremental update to its operating system, iOS 17.0.3, to resolve the overheating problems plaguing iPhone 15 Pro and iPhone 15 Pro Max users. This update, long-awaited by the affected users, promises to alleviate the heat-related concerns that have been persistently reported since the launch of these two flagship models.
iOS 17.0.3 identified by its build number 21A360, tackles overheating issues and addresses a critical kernel vulnerability. This vulnerability could grant attackers elevated privileges, posing a significant security risk. Apple has confirmed that this flaw was exploited in iOS 16.6 and earlier versions. As a result, even users with devices other than iPhone 15 Pro and iPhone 15 Pro Max are strongly advised to update their devices promptly.
Thermal Imaging Tests Confirm Success of iOS 17.0.3 in Resolving Overheating.
To substantiate the effectiveness of the iOS 17.0.3 update in resolving overheating problems, ZDNET conducted thermal imaging tests on iPhone 15 Pro devices. The results of these tests indicate a noticeable reduction in device temperature during fast charging.
Before the update, iPhone 15 Pro and Pro Max users experienced significant heat buildup while engaging in activities such as fast-charging or using certain third-party apps like Instagram, Uber, or Asphalt 9. This heating issue was believed to be linked to a software bug rather than any hardware or design flaw in the iPhone 15 Pro models, which introduced a new titanium frame with an aluminum substructure.

In testing with the iPhone 15 Pro and Pro Max, one prominent overheating issue was identified during fast charging. The iPhone 15 Pro Max, when charged using Apple’s USB-C cable connected to a 35W charging brick, would become excessively hot to the touch. Replicating this experience in a different location with the same cable and charger yielded consistent results. A thermal camera was employed to measure the heat, revealing that the iPhone 15 Pro Max reached temperatures as high as 107.1 degrees Fahrenheit.
With the release of iOS 17.0.3, Apple has effectively tackled these overheating concerns, offering relief to iPhone 15 Pro and iPhone 15 Pro Max users. The update is expected to usher in a more comfortable and trouble-free user experience, particularly when engaging in power-intensive activities.
iOS 17.0.3 is a significant milestone for iPhone 15 Pro and Pro Max owners, addressing overheating issues and enhancing device performance. Regardless of their device models, all users must install this update promptly to ensure optimal security and functionality. Stay tuned for further updates as Apple continues to refine its operating system to meet the evolving needs of its user base.
