iOS 11: How to install the latest version of the iPhone and iPad operating system

iOS 11 is now available, and you probably want to upgrade. The upgrade process will take several minutes, and you should probably use a Wi-Fi connection so you don’t eat up your data allocation with your service provider.

And before you upgrade, it’s important to back up your device. If you sync with a Mac, you can back up in iTunes. You can also back up to iCloud.

Also, this version of iOS ditches 32-bit apps for more modern 64-bit apps, so if any of your favorite apps are still on this older standard, they won’t port over properly. To check on your apps on iOS 10 before you upgrade to iOS 11, go to Settings > General > About > Applications, and you’ll get a list of apps that won’t make it through the upgrade process. 

There are two ways to install iOS 11. The first allows you to do it directly on your iPhone or iPad. The second lets you do it by connecting your device to your Mac.

How to upgrade to iOS 11 on your iPhone or iPad

  3. Your device will check for an update, which can take a few seconds, depending on the speed of your internet connection. You’ll see the screen below when it’s ready. Note that the upgrade is over 2GB, which is why you should use a Wi-Fi connection.
