The BB uses a Lithium-ion battery. There is no need to auto discharge. In fact, it works best if you keep it topped off. If the powers gets below 20% you can actually damage the battery.

Agreed.

I do the same thing, charge every night while sleeping, and always have. It doesn't hurt anything. I also top off sometimes during the day. Not necessary to fully discharge like the old NiCd batteries.
