I have just got myself an iPhone 7. With this one I have used my old iCloud back-up to update it, without problem. Yesterday I checked if my new phone has made a back-up to iCloud which it hadn't. So I started the process manually. It finished this night but it's just 3.9 GB while my old (iPhone 5S) is 11.4 GB (see picture). I have 50 GB storage space in iCloud. I don't trust this new back-up is complete, the icon beside also looks weird. What is wrong and what do I do? I back-up is essential for my mental health ;-)
