I just received my new iPhone 6s this afternoon. I started restoring it from backup from icloud 2 hours ago, but the remaining time keeps on changing: now it says it will take about 5 more minutes, but it has been saying this for over an hour now. Is this normal? The backup is not that big btw, I deleted all my apps on my previous iPhone before I made a new backup because I only wanted to save my pictures and messages.
