iOS 18 is finally here, with a host of new features, major redesigns, and, most importantly, Apple Intelligence. While the iPhone 16 series comes pre-installed with iOS 18 out of the box, you will need to install the OS on other iPhones that support it manually. However, to be able to do that, you first must ensure whether your iPhone supports iOS 18; if yes, a few things need to be taken care of before hitting that download and install button.
The post details how to prepare your iPhone for the iOS 18 update and how to update it to iOS 18.

For the first time ever, Apple hasn’t omitted any device that supported the previous iOS generation from the new generational iOS-supported devices list.

How to prepare your iPhone for iOS 18 update
As mentioned, before you begin the iOS 18 update process, you must perform a few actions to ensure no data loss or interruptions.
Backup your iPhone
Although the iOS 18 update process is typically smooth, it is always wise to back up your iPhone to iCloud on your Mac before updating it to a generational iOS update. This ensures your important data remains safe and recoverable in case of an unexpected issue. Precaution is always better than cure, right?
Connect the iPhone to a stable Wi-Fi network
While your cellular 5G data often offers a faster internet speed than your Wi-Fi, using it to update your iPhone isn’t wise. iOS updates are generally large and can quickly eat up your daily data threshold, interrupting the update process in the middle. So, connecting your iPhone to a stable Wi-Fi network ensures reliable downloads and a stable transition to iOS 18.
Charge your iPhone
Apple says that your iPhone must have at least 50% charge to update iOS. So, make sure you connect your iPhone to the charger or keep it charged beforehand before starting the iOS 18 update process. Otherwise, the update process may not start or could be interrupted.
