I am trying to setup my icloud storage backup and I have all app turned off and have turned off all other things to store as well, yet my "Next Backup Size" is saying 18.0 GB... Nothing I do will change this 18 GB. I don't have photos or music set to be backed up. I've tried deleting the account and starting over, as well as re-booting the iPhone... Nothing will work. Can someone please help me?? I'm going nuts here-lol... Thank you guys
