Hard to say really as so many things could be affecting it. Few have noted that leaving background data enabled for all apps helps prevent the OS draining.
In my experience some apps will use data but it isn't registered as that app that's doing it so it gets registered as the OS. I imagine there's a tool available to see all data requested but it would most likely need root access.
