So I'm walking the walk and deleting a gut of unused old contacts off my own iPhone today. While doing so won't free up lots of space on the device, it will put a few megabytes back into play, and it will save me a lot of time as I scroll through my contact list searching for that name and number I need.
Whether you have left a job, ended a relationship, or you never really needed the phone number of the guy who cleaned your gutters one time in 2014 anyway, you can quickly and permanently delete contacts off an iPhone in five simple steps.
How to delete contacts on an iPhone
Before you can delete those contacts, you need to open up the contact list. Tap the green square with the white phone inside it to open up your phone's various functions, then hit the pair of heads with the word "Contacts" below it, or go to the Contacts app.
1. Scroll down to the contact that you wish to expunge from your phone.
2. Tap on the contact to open its page.
3. Tap "Edit" at the top right corner of the contact's page.
4. Scroll to the very bottom of the next page.
5. Hit the words "Delete Contact" written out in red.
6. Tap the red "Delete Contact" that pops up.
And that's it, the contact is deleted.
You might consider blocking a contact instead of deleting it
If there is a number (or 10 or 20) in your contact list that you are certain you'll never need (or want) to call, text, or FaceTime again, then by all means go ahead and delete it.
But keep in mind that you can't undo this action; once that contact is removed, it will have to be recreated from scratch should you change your mind. And don't think the cloud can help you! The contact will also be removed from any device that has your iCloud Contacts turned on .
However a deleted number that was never blocked can still get in touch with you.
