To update your iPhone to iOS 18, ensure your device is compatible and has a stable Wi-Fi connection. Your battery should be at least 50% charged. We also recommend backing up your iPhone before updating it. Go to
- Settings
- General
- Software Update.
If an iOS 18 update is available, tap Download and Install. Enter your passcode, agree to the terms, and wait for the download and installation to complete. Your iPhone will restart automatically once the update finishes. You can enable automatic updates to keep your iPhone up-to-date without manual intervention. Go to:
- Settings
- General
- Software Update
- Turn on Automatic Updates.
If you encounter any issues during the update process, refer to Apple's official support documentation or contact Apple Support for assistance.
