My other must be "Documents and App Data".
I did and update other data was 3.2GB
a fresh install other data dropped to 0.48GB
a fresh install+ restoring from iCloud backup other data went back to 3.2GB
a fresh install+ only downloading apps from app store not previously saved app data and Other dropped to 0.65GB.
And when I compare my "Other" capacity shown from iTunes to what my iCloud backup is, they are almost identical, off about 200 or so MBs.
My phone shows 3.3GB backup
My Other shows 3.1GB
I only have 2.5GB of Free space on the phone and none of the other #'s are anywhere close to my iCloud backup size except for.
Yeah I'm thinking the Other for me is messages - I've got a lot of media in them - images and videos. Wouldn't have thought it'd be 2gbs worth though!
Sorry for reviving an old thread, just wanted to throw some info into this "Other".
I'm sure it's iMessages now.
I sent a 2 minutes video clip to 2 contacts, then say my other and iCloud backup size increase by roughly what I'd expect the video's filesize to be (times 2).
So I delete the message with the attachment from both message threads, did the iCloud backup and checked Other again, and it hadn't decreased.
Seems that even when you delete a message, it doesn't delete the attachment from the file system.
Confirmed this using some backup recovery software. It doesn't see the message (because I deleted it) but it does see the video file twice, so it's not been deleted... waste of about 500mb that I can't get rid of!
