Correct me if I'm wrong, but the cell phone is going to be using about the same power when its plugged in and fully charged as it does when it is unplugged. The difference is only that the power is coming from the outlet, rather than the battery in the phone. Without some calculations on how much would be drawn from the battery, simply from having the phone on over night, its hard to say what kind of power savings are available. I would guess its next to nothing, even less than they make it out to be in the article.
