Unless you’re doing several thousand km a week it shouldn’t need charging that frequently. Either knackered battery, a short somewhere or you left something pressed against a lever.

I was under the impression that the wireless D-Fly thingies were a battery drain.

As @grams said it may be the case If you don’t disconnect. Ive never done that tho. Leaving it leaning against a post with the shift button pressed in, yes.

They'll use some power in use, as there's no such thing as a free lunch, but shouldn't when the system goes to sleep. I've got them on a couple of bikes, and they still only need charging once every few months.
