Overview
- iOS 26.5.1 is available through Settings for iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max and iPhone Air and addresses a bug that could leave phones unresponsive after deep battery discharge.
- The update, confirmed in Apple’s release notes, specifically fixes cases where connecting a USB-C cable produced no battery indicator or reaction on nearly empty devices.
- Users who reported the problem in late April found that MagSafe wireless chargers often revived affected phones when USB-C charging failed, and Apple built the patch in response to those reports.
- Apple labeled 26.5.1 as a targeted stability fix with no security patches, reflecting a narrow scope rather than a broad feature or safety update.
- The release on Tuesday comes days before WWDC 2026 and signals iOS 26 maintenance winding down as Apple prepares to publish iOS 27 betas after the conference.
