Go to your mobile data usage screen, and one by one restrict all apps that do not need cellular data for your usage. Youtube is a good example for me where I do not allow cellular data usage, but wifi is wide open.
Note also that Verizon uses your data allotment to ping towers. Its not a lot, but it is something. So if you are like me and live in an area with weak cellular coverage your cell radio will consume data and battery just trying to acquire tower signals. I turn off my cellular data when I am at home.... unless I need to turn it on for text messaging or voice mail downloads.
There's a global setting to ONLY allow app updates over wifi... you'll definitely want to do that.
