Oh man, I remember when I got my first new iPhone - I was SO paranoid about losing all my photos and messages! The trick is to start the restore process right during the initial setup when you first turn on your phone. I learned the hard way that you need to keep it plugged in the entire time because my phone died at 90% once and I had to start all over again. The Wi-Fi connection is super important too - make sure you’re on a reliable network or you’ll be waiting forever!
