It is, but it didn’t used to be. Way back at the dawn of the smartphone era I was working in consumer telco here in Aus, and half of my day was spent making sure people kept their data between phones. Even going from one android phone to another wasn’t a great guarantee, and for iPhones we used to have a computer to take a backup via the 30-pin.

These days cloud backups and the like make it pretty simple on both operating systems.
