Be Prepared to Wait

When iOS 18 and iPadOS 18 become available as an over-the-air update, make sure your device is fully charged before you start the process over Wi-Fi, as it may take some time to complete. To check that the update is available, go to Settings > General > Software Update, and wait a moment for your device to contact Apple's servers. If you're in no rush, you can wait for iOS 18 to be delivered to your iPhone when you next plug it into your computer.

Tips and Precautions

• Make sure your device is fully charged before updating.
• Update your device over Wi-Fi to avoid data charges.
• Be patient, as the update may take some time to complete.
• If you're in no rush, you can wait for iOS 18 to be delivered to your iPhone when you next plug it into your computer.
• During the initial rollout of major software updates, Apple users may experience slower download speeds and sluggish performance due to the surge in traffic on Apple's servers.
