icloud is full. Backup only 2.5gb. Only saving contacts and calendar data which surely can't be the other 2.5gb. Help please!
Ever since updating to iOS 9, my phone now says that my iCloud allowance (5gb) is full and phone is no longer backing up to icloud. However my backups only add up to 2.5gb. I only save contacts and calendars to iCloud - not photos or anything. I recently deleted all backups and turned off contacts and calendars - and still 2.5gb was being used - I just can't see how! I know additional cloud space is inexpensive but I don't want to be to buying something I shouldn't need. Any advice please? Thanks!
iPhone 6, iOS 9.0.1
