Apple releases iOS 18.1 for compatible iPhones with a focus on security and visual adjustments
Apple began distributing iOS 18.1 this Wednesday, November 5, 2025, for compatible models starting with the iPhone 11. The update, measuring approximately 2.6 GB, introduces interface refinements and security fixes, meeting demands for stability after the initial release of iOS 18. Developers and beta testers reported improvements in tactile and visual responses, without the need for an immediate restart.
How to install the update on the device
Users access iOS 18.1 directly through the Settings app, in the General section and then Software Update. The process downloads the file in the background and installs it within minutes, depending on your Wi-Fi connection.
Automatic download option enables minor updates without interruption, making maintenance easier.
Reports indicate that the update corrects slowdowns in older models, such as the iPhone 11.
Supported Templates and Minimum Requirements
iOS 18.1 operates on iPhones released since 2019, including the 11, 12, 13, 14, 15 and 16 series. Second and third generation SE devices also receive the package, as long as they have an A13 Bionic processor or higher.
