Inaccurate backup size.
I am forever having difficulties backing up my phone to my iCloud (free 5GB). I have deleted all existing backups, so my iCloud is empty. The only things that I am attempting to backup are contacts, calendar, and notes. Nothing else is set to backup to iCloud. Yet I’m being told that it will take over 5 gigs of space to backup those three things. There is no way that info would take 1 gig of space much less 5. Any advice?
