iPhone: delete all contacts at once - how it works

With iPhone, you can only delete your contacts individually using the standard app. With a trick you can delete all contacts at once. We show you how to do this.

Delete all contacts from iPhone at once

1. Go to the home screen of your iPhone and open the Settings app.
2. Scroll to and tap the Mail, Contacts, Calendar entry.
3. Under "Accounts" you will now see the accounts with which your contacts are synchronized. You can recognize them by the entry "Contacts" under the name of the respective account.
4. Now tap on one of the accounts, for example "iCloud".
5. Then deactivate the "Contacts" option and then tap on "Delete from iPhone".
6. Do the same for all other accounts that synchronize your contacts.

Last step: delete remaining iPhone contacts

However, you still have to delete contacts that were not synchronized with an account:

1. To do this, open the Contacts app and tap on a contact.
2. In the top right, choose the "Edit" button and scroll all the way down to delete the contact.
3. Alternatively, you can use third-party apps that even let you delete multiple contacts at the same time.
