Why is there an additional 10GB of iCloud data wanting to be backed up on 3-hours?

I backed-up my iPhone 3-hours ago which had a backup size of 67.09 GB.

Since then, there are 15 new photos, and KB of files, with a new backup size of 77.86 GB, with an initial statement of Next Backup Size +30.76 GB!

I have all analytics disabled and maximum privacy settings enabled so as to not share anything with Apple or third-party apps.

Where is this another data originating from and why is it being uploaded to my iCloud?

iPhone 12 Pro Max, iOS 18

Thanks @RandomUser360,

• Files (in my Folders 25.98 GB and Downloads 1.74 GB) = 27.72 GB

• Photos = 28.47 GB

• Messages = 8.6 GB

Total = 64.79 GB (with no other apps saved, lockdown mode, all other privacy settings set to maximum).

Yet, the Backup states 77.46 GB!

Where could the additional 12.67 GB be originating from and for what possible reasons?

This excellent User Tip should help. It focuses on clearing iPhone storage, and as iCloud backup side is affected by what is on your device, I suggest trying it out.

Check the settings for the backup. It should tell you how much space is used by each app. Hope this helps!

Maybe it's a bug? You should restart your phone to check if that's still the case.
