    Before updating, it's always advised to create a backup in case something goes wrong. This should only take a minute or two, and will allow you to restore your iOS device along with all your data if an error occurs during the update process, or if you like the old operating system better. [8]

    This will download the update to your computer, and apply it to your iOS device. This process may take a while, and you can monitor the progress of the update on your device's screen. [10]
