Storage data different on iPhone and iTunes

i had this problem also but have managed to sort it out.

Not sure how the decoupling came about but i'm thinking it might be because at one point i had my phone backing up to iCloud...that's just a speculation. did you ever back up to iCloud?

in any case, the steps i took to rectify the situation were:

1) back up phone

2) in iTunes, uncheck the categories of things (eg. books, music, tv shows) being synced

3) from phone look to see what's taking up space that iTunes is responsible for... to do this go: settings -> general -> usage -> storage

4) delete the stuff on there you don't want sitting on there...in my case it was some audiobooks in the music section...(i think they were there from ages ago - i had unchecked them in iTunes some time back)

5) go back to iTunes, re-check the categories of things (e.g. books, tv shows etc) you want synced.

6) sync iphone

- you might be able to just go into the usage folder yourself and identify stuff in there that is not accounted for by iTunes...but i think the method above is less tedious.

please let me know if it works for you...

good luck!

I have this problem but on my phone there are no books/music or other documents.

In iTunes no categories are checked/synced.

My music is on iCloud.

I have photos and I was thinking that this may be the problem. I have therefore disabled photo stream but the gap between phone storage and iTunes is still there. The difference is around 2 GB.

I also have 1.9 GB of Other field, visible on iTunes.

After 2 years of usage I feel like my iPhone 5s needs a hard reset but I really do not understand why this issue is there.

I have the same problem on my iPhone 6 as well. Unable to identify the gap and that drives me mad!

Same here too. I think that the space info is correct via iTunes because on my iphone the "used" + "free" doesn't add up to the iphone capacity.

Continuing to search for a solution away from hard-reboots

I have the same problem and it's driving me nuts!

Please if anyone has a solution to this please do share. I have the same issue on all my devices. Ipad, Iphone 5s, Iphone 5.

I did a hard reset, but restore the phone with previous backup in order to get my info. So this doesn't work.

I feel like doing a hard reboot and doing a fresh sync, but i don't want to loose all the info.

Please HELP!!!

Same problem with my iPhone 6. It says that the storage is full and iTunes says I should have 1 or 2 gigs free. I have restored several times and everything works fine for a few days/weeks.

Same problem with my iPhone 5S. It says that the storage is almost full and iTunes says I should have 3 gigs free. I have restored several times and no change.

I also have this same problem on my 6 Plus. I've done a hard reset and I really dont want to reset to factory. I think the problem may lie in the applications though, any ideas? Perhaps clearing up the app cache of each app somehow

I have the same problem on my iPhone 6 Plus running iOS 8.4.1

My Music is stored in the cloud, photos as well and my phone tells I have 5.4GB left while iTunes says 8.54GB. what the...???? I have uninstalled Facebook, Messenger, Instagram and other social media apps (apps which store a lot of data) then reinstalled them because I have nothing to lose by doing it. but still there is a huge free space difference. I don't understand why, but at least I found this article so I know I'm not the only one experiencing this.

If anyone finds a solution, please do share with us!

Thanks

P.S: I really don't want to restore my phone

Same problem on 4S. Anyone?

Same issue on my iPhone 6.

Yes, same issue on 4s.

I having the same issue, But it's a iPodTouch 5G. It bugs me a lot, I'm not going to restore the thing though.

I have the same issue with my Iphone... I see that this thread has been viewed by 10637 people - and the Apple tech support hasn't bothered to yet answer any one of us?!!?!?! How the **** does this process work if no one from Apple responds to our questions?!?!?!
