I get the latest iPhone every year and every year I usually just set up my device from an iCloud backup. My current iPhone 6 seems to be working just fine. Would setting up my iPhone 6s as a new device benefit me at all or should I continue restoring from backups like I have in the past? I have asked this question before and only received opinions on what I should do. Is there any hard core facts out there that state one is better than the other?
