4 Get Rid of Old Text Messages & Contacts
Unless you’re saving a text thread for the important information contained within, it’s generally a good idea to go through and delete older text threads in Messages. You’d be surprised how much data they can take up. Just open Messages, view your list of conversations, swipe left on a message thread, and tap Delete.
Similarly, it’s a great time to clean up your Contacts. It’s probably smart to get rid of phone numbers for those people you haven’t spoken to in years — or, obviously, any person you don’t remember. More importantly: delete any duplicate contacts or old phone numbers for your friends who got new lines. Just tap a contact, tap Edit, scroll all the way down, and hit Delete Contact.
