iOS 26.5.1 is now available for iPhone 17 models and iPhone Air, targeting a bug that could block wired charging when the battery was nearly drained.
Apple said the issue affected only a small number of users; the update is available through Settings, General, then Software Update.
Late April reports had flagged the battery-drain-related charging problem on iPhone Air, and Apple may have included other minor fixes not listed in its notes.
The patch follows last month’s iOS 26.5 release, which added RCS end-to-end encrypted messaging and a new Apple Maps feature, while iOS 26.6 remains in beta ahead of WWDC 2026.

With Apple and Google collaborating on RCS, why are basic functions like charging failing on brand-new flagship iPhones?

Beyond the software patch, could a hidden hardware flaw be the true cause of the iPhone 17's critical charging bug?
