iphone 6 double backups on phone...

when you look in his icloud backup under manage, how many devices does it show? the phones backup will say "This iPhone" underneath it.

Sounds like its time to clean out the iPhone's Camera Roll if the backup is getting too large for iCloud. Either that or there are on-board documents associated with apps that are making the backup too big. iCloud can hold the backups of multiple devices, if you keep them lean.

So backup to iTunes if you can (for safekeeping), then do some iPhone clean up, then try an iCloud backup once again.

Each individual phone maintains it's own individual backup on icloud, so if he upgraded from an older phone and restored that backup to his new phone, or if he got a warranty replacement phone at some point and restored an icloud backup to it, then the original backup would remain on icloud and the new phone would create it's own backup.

If he doesn't need the backup from the original phone anymore, then you can go in and delete it as described above.
