I recently upgraded my Note 2 to a Note 4. One of the first things it asks when you first switch on the phone, is to log into your Google Account. After that it asked a couple more questions. By the time the install wizard was done, most of my phone had been restored: Apps Contacts (including favourites) Emails (they live in the cloud) Photos Music Even things like WiFi passwords, preferred hotspots, etc.

I don't even think about backing up and restoring my Android device. It all just works.
