My last backup on my iPhone 5 with iOS 8 was about 2.1 GB. I upgraded to iOS 9 and it was complaining about not having enough space to backup. I paid $0.99 to upgrade to the 50 GB iCloud. The backup finished and it is 7.5 GB!
What is going on with iOS9 backup?
Hi, same issue here. I had to upgrade to 50GB but never had this issue before... this is a very strange and unexpected behaviour since it is resulting in unexpected and unplanned extra costs... maybe it is an issue that it is going to be fixed... ???
I suggest looking at Settings->iCloud->Storage->Manage Storage
and see what is taking up your space.
It looks like a bug in the backup.
It said it was backing up my Photo Library and the size of that library was 2.5 GB. I turned off Photo Library and the size of my backup went from 7.5 GB to 955 MB! I then reenabled and then disabled Photo Library and the backup size went to 908 MB. So it looks like whatever estimates backup sizes is out of whack.
So for anyone experiencing this problem, I suggest you turn off Photo Library or toggle it to see if you can get a size estimate that allows your backup to go through.
Why are backups on iOS9 so huge?
