Apple released iOS 26.5.1 on June 1 to address a charging problem that affected a small number of iPhone 17 and iPhone Air users whose devices would not charge via cable when the battery was nearly drained [1, 2]. The issue caused devices to display a black screen with no charging indicator when plugged in by cable near empty battery. Users could temporarily revive their phones only through MagSafe wireless charging [1, 2].
The charging bug was first reported in April 2026 by a limited group of users experiencing the problem [1, 2]. Since then, Apple worked to deliver a focused bug fix without adding new features or security patches, releasing iOS 26.5.1 in just 21 days after the prior update[iOS 26.4] [1].
Apple emphasized that iOS 26.5.1 is a targeted maintenance release aimed solely at resolving the charging glitch without any user interface changes or additional functionality [1, 2]. The company plans to concentrate on bug fixes and stability improvements throughout the rest of the iOS 26 lifecycle [1, 2].
Apple’s upcoming iOS 27, expected to be announced at WWDC 2026 in June, will deliver major new features. It will drop support for iPhone 11, 11 Pro, 11 Pro Max, and iPhone SE 2 models, while introducing AI-powered features for the Camera and Photos apps [1].
Users affected by the charging issue can update to iOS 26.5.1 by navigating to Settings > General > Software Update on their iPhones [2].
