This article covers some of the things you can do to prepare your devices for Apple's latest mobile operating system, including storage maintenance tips, backup advice, and a few other useful tidbits to consider before upgrading. First though, it's worth finding out if your mobile devices are compatible with iOS 11.
iOS 11 Compatibility Check
If you own an iPhone 5s or later, or an iPad Air or later, your device will run the latest operating system. Still unsure? Here's Apple's official compatibility list for iOS 11.
- iPhones: iPhone X, iPhone 8, iPhone 8 Plus, iPhone 7, iPhone 7 Plus, iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, iPhone 5s, iPhone SE.
- iPads: 12.9-inch iPad Pro (1st and 2nd generations), 10.5-inch iPad Pro, 9.7-inch iPad Pro, iPad Air 2, iPad Air 1, iPad 5th generation (2017 model), iPad mini 4, iPad mini 3, and iPad mini 2.
- iPods: iPod touch 6th generation.
Reclaim Device Storage Space
iOS 11 includes new features to help you free up space on your iOS device, such as personalized recommendations about actions you can take to increase the available storage. But before you can benefit from those, you'll want to make sure your device has adequate space to download and install the new operating system.
With that in mind, it's worth reconsidering what apps you currently have installed on your devices and whether you really need them. Swipe through your home screen and check inside your folders to root out any long-forgotten apps (including legacy 32-bit apps that won't work on iOS 11) that are taking up precious storage space.
You can delete apps by holding a finger on them and tapping the X that appears at the corner of their icon. Alternatively, go to Settings -> General -> Storage & iCloud Usage -> Manage Storage, tap any apps you don't use, and select Delete App. Be ruthless – you can always re-install removed apps at a later date if you change your mind.
Check on the size of any social media apps you have installed, such as Facebook and Snapchat. These apps can often balloon in size after long periods of activity because of media caching and the like, so you might want to delete and then re-install them to start afresh.
If you're a WhatsApp user, open the app, go to Settings -> Data and Storage Usage -> Storage Usage, take a look at how many megabytes your chat history is consuming, and take appropriate action using the "Manage" option. You might be surprised at the savings this simple step can make.
If you use iCloud Photo Library, it's also worth checking that it's set up to use as little local storage on your device as possible. Tap through to Settings -> Photos and Camera, and make sure the option "Optimize iPhone Storage" is ticked. Lastly, open the App Store app and install any updates that are available to ensure maximum compatibility with iOS 11.
Create an Archived iTunes Backup
It's best practice to have an iTunes backup of your device stored on your computer in case something goes awry, or the worst happens and installation of iOS 11 fails. If you need to downgrade shortly after installing a new iOS update, making an archived iTunes backup beforehand is necessary.
An archived iTunes backup saves the current state of your iOS device and prevents it from being accidentally overwritten by subsequent backups. Here's how to do it on a Mac. (Note that if you're a Windows user, the iTunes procedure varies slightly and you will need to rename your iTunes backup folder or move it to another location to prevent it from being overwritten).
- Connect your iPhone or iPad to a Mac with the latest version of iTunes installed (click iTunes -> Check For Updates from the menu bar to make sure) and click on the device's icon in iTunes' interface.
- Under backups, select "This computer", choose "Encrypt iPhone backup" and then set a password. An encrypted backup retains all your account passwords as well as your Health and HomeKit data, whereas a non-encrypted backup doesn't.
- Click "Back Up Now" and wait for the backup process to finish. It should take between 5 to 15 minutes to complete depending on how much data is stored on your device.
Archive the Backup
- To archive the backup, select "Preferences" from the iTunes menu and click on the "Devices" tab. Right-click the new backup and choose the "Archive" option.
- After the archival process is complete, a backup is labeled with the date and the time that it was archived.
Installing iOS 11
When iOS 11 becomes available (likely around 10 AM PST/1 PM EST on Tuesday, going on past releases) it will be delivered to your device either via iTunes when you plug it into your computer, or 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.
