Sometimes it's a good idea to factory reset your iPhone. Perhaps your phone is acting up and you want to troubleshoot it yourself before making an appointment at the Apple Store. Or maybe you want to wipe or erase all the content off your iPhone before you sell it or give it to someone else. Whatever the reason may be, when you factory reset your iPhone, all the content and all your settings and preferences will be permanently removed from the device. So, it's important to back it up first to make sure you don't lose anything important.
