How to Prepare for iOS 13.3
If you're planning to move your iPhone XR to iOS 13.3 today or sometime soon, make sure you prepare yourself and your device for the move.
There's no way to predict exactly how iOS 13.3 will run on your device so it's important to prepare for the installation.
If you don't know how to do this, please take a look at our pre-installation guide. It will take you through the process we use before we install new iOS software on our iPhones.
If you don't have the free time to do this, be sure to backup your files. Data loss issues are rare, but you'll want to play it safe.
