The iPhone 15 Pro and and iPhone 15 Pro Max are not off to a great start, courtesy of widespread user reports of overheating during charging and while using certain apps. While this did put off the initial excitement about new iPhones to some extent, Apple quickly acknowledged the heating issue and promised to release a fix. Today, the Cupertino giant has rolled out the iOS 17.0.3 update, wherein the patch confirms this addresses the problem of iPhones warmer than expected.
Apple releases fix for iPhone 15 Pro heating issue
- The iOS 17.0.3 update weighs around 430MB in size (could vary based on model) and is rolling to all eligible iPhones worldwide.
- While there were speculations about hardware issues, possibly circling around the more powerful A17 Pro processor or titanium components for the heating issue, Apple’s recent statement attributed this to a software issue.
- This is alongside when using USB-C chargers.
- This new update comes after Apple had previously released a patch to fix the data transfer problems experienced by a few users.
- As for beta, Apple is currently in the beta testing phase for the iOS 17.1 update and this should make its way to the general public very soon.
In an update outlining the security fixes within this patch, Apple identified two vulnerabilities, which were fixed for iOS and iPadOS. Among the two, the first was a kernel exploit that could be exploited by an attacker with local access to the device. Apple mentioned that it “may have been actively exploited against versions of iOS prior to iOS 16.6.”
The second fix is regarding a libvpx bug, which previously raised concerns flagged by CISA. This potentially allowed a remote takeover of the device. This libvpx bug was recently patched in applications like Chrome and Firefox.
Downgrading from iOS 17 to iOS 16 is no longer possible
While the fix to the heating issues aside, following the release of iOS 17.0.3, Apple has stopped signing iOS 16.1.1, iOS 17, and iOS 17.0.1, thereby preventing iPhone users from downgrading to any of the older software versions. However, Apple is continuing to sign iOS 17.0.2 for now.
This isn’t anything new as Apple usually stops signing older iOS releases over time to prevent users from downgrading to previous software versions.
