Apple has recently rolled out the iOS 26.5.1 just weeks after the Cupertino giant released the iOS 26.5 update. Unlike the last update that introduced fresh features for your device, the current update is focused on fixing a specific issue affecting a small group of users. After the users updated to iOS 26.5, many iPhone 17 and iPhone Air users reported that they have been facing a problem that prevents devices from charging through a wired connection when the battery level becomes extremely low. Taking the users’ complaints into account, the company has now released an update to help fix the issue. Here’s everything you need to know about the latest iOS 26.5.1 update.
SurveyWhat’s in the iOS 26.5.1 update

How to update your iPhone

You can update your device to the latest build much like you do a normal software update. All you need to do is head to the Settings app > General > Software Update. Once the update appears, choose Download and Install to begin the process.
The size of the download will depend on the software version that’s currently installed on your device. On an iPhone 17 Pro Max running iOS 26.5, the update size is reported to be 17.44GB. Users updating from older versions may see a larger download and longer installation time.
