iOS 11 adds several features aimed at optimizing storage space on the iPhone and iPad, such as Messages on iCloud and the ability to offload apps.
Mac users may have noticed there is no built-in way to change where iTunes writes backup information. This means every time an iPhone, iPad or iPod touch is backed up to the computer using iTunes, it automatically uses the local drive. Rest assured, it is possible to tell iTunes to put backups on an external drive. Once the steps below are implemented, all iOS backup data will be saved to the new location.
Web browsers are always collecting information, and Safari on iOS devices is no different. iPhone owners interested in enhancing privacy can use private browsing when opening a new Safari tab. But what about all of the cookies, browsing history, login data and other files that accumulate during a normal web session? There are two places in iOS where this information stored by Safari can be manually deleted at any time.
Some iPhone owners may not have noticed, but iOS automatically saves deleted visual voicemails. The deleted voicemail messages go into a folder, which is appropriately named Deleted Messages. Depending on the carrier, contents of Deleted Messages can be saved indefinitely. iOS does not provide a way to clear out this folder automatically, so it must be done manually. To free up more storage space on the iPhone, here's how to delete old voicemails once and for all.
It's no secret that running out of space on the iPhone causes issues. Free storage space is needed for iOS to run properly, not to mention for the installation of system updates and new apps. Music is easily synced provided the songs are in iTunes, and iCloud users can store music remotely to save space. When needed, deleting all of the music tracks on an iOS device is an easy way to free up extra space quickly.
Make sure the music on your iOS device is stored elsewhere before following this tip. Individual songs and playlists can be deleted by swiping right to left directly in the Music app. To quickly wipe out all of the music on the iOS device follow these steps.
