How to Recover Space by Offloading Unused Apps in iOS 11
Running low on space on your iPhone or iPad in iOS 11? This problem may be easier to deal with than you expect because Apple has added a quick way to free up storage space by removing unneeded apps. Go to Settings > General > iPhone/iPad Storage, where you’ll see a Recommendations section. This section may include an option to Offload Unused Apps with an estimate of how much space you could save. Tap Enable to allow iOS to remove apps that you haven’t launched in a while—this happens only if you’re low on space. iOS preserves any documents or data associated with the offloaded app, and the app’s icon remains on the Home screen, with a cloud badge. Tapping the app icon reloads it from the App Store, assuming it’s still available. If you find yourself waiting for apps to reload often and you can clear space in other ways, you can disable the feature in Settings > iTunes & App Store > Offload Unused Apps.
