On 04 Oct, Apple has introduced the iOS 17.0.3 update for the iPhone, following last week’s release of iOS 17.0.2. Additionally, a corresponding update, iPadOS 17.0.3, has been made available for iPad users.
To obtain the iOS 17.0.3 and iPadOS 17.0.3 updates, you can access them via over-the-air download on compatible iPhones and iPads by navigating to Settings > General > Software Update.
iOS 17.0.3, identified as build 21A360, resolves a noteworthy overheating concern specifically affecting the iPhone 15 Pro and iPhone 15 Pro Max. Following the recent debut of the iPhone 15 series, users voiced concerns about excessive heat, and in certain instances, device shutdowns due to heat-related issues.
Apple officially acknowledged the bug in late September and assured users that it would be rectified through an upcoming iOS 17 update. The issue was exacerbated by certain third-party applications that were pushing the A17 Pro chip to its limits, causing heat-related difficulties.
Notable apps contributing to performance problems included Instagram and Uber. In tandem with the iOS 17 update, Apple has also been collaborating with app developers to optimize these problematic applications.
In statements made to MacRumors, Apple provided clarification, assuring customers that the temperature-related concerns would be effectively addressed through a forthcoming update. Apple also emphasized that the titanium frame of the iPhone 15 Pro was not responsible for the issue.
Notably, Apple analyst Ming-Chi Kuo posited that the overheating problem likely stemmed from “trade-offs made in the thermal system design.” He further suggested that rectifying the matter might entail reducing processor performance.
Apple confirmed that it has no plans to make adjustments to the A17 Pro chip, asserting that the combination of titanium and aluminum in the iPhone 15 Pro design actually enhances heat dissipation, surpassing the performance of stainless steel frames used in prior models.

The iOS 17.0.3 and iPadOS 17.0.3 updates also tackle a kernel vulnerability that had the potential to grant unauthorized access and elevated privileges to malicious actors. Apple acknowledges that this security loophole had been exploited on iOS versions predating iOS 16.6.
