Si which one have you got? My latest Halo B doesn't seem to drain after I have turned it off. I don't know if maybe they upgraded the software on later versions or something?
Mine also drains the batteries dry if they are left connected. Was also rather irritated but once it was plain what was going on I just started to disconnect them end of every day. Couple of minutes.
Picked mine up at IAO in August.
