The EASY way to backup your iPhone contacts

How to backup your contacts on the iPhone

 

Once you turn on the backup for contacts, you will see that all your contacts will now be saved on the iCloud and you can quickly access them through the iCloud website for PC. Now, if your iPhone needs to be factory reset due to some problem, or it has been wiped during a servicing run, you can then restore your iCloud backup and your contacts will be restored as they were before the reset was performed.
