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.
On that note, a word of caution: During the initial rollout of major software updates like iOS 18, Apple users may experience slower download speeds and sluggish performance when trying to update their devices. This is largely due to the high demand on Apple's servers, as millions of users worldwide attempt to download the update simultaneously. 
The surge in traffic can overwhelm network capacity, leading to delays in downloading or installing the update. To avoid these potential issues, you may want to wait a day or two before installing the update, allowing server congestion to subside and ensuring a smoother upgrade experience.
