Yes, it should auto reconnect. I find the constant reconnect popups annoying to be blunt. As for fearing battery consumption.. After finishing emulation, to conserve the batteries you should always open Wiimote battery lid and press red reset button so that bluetooth stack stops reading it's status. That certainly solves the battery draining problem.
Or, just disconnect BT dongle from the computer, or take out battery pack and put it back in.
(I didn't know this earlier, and just after 3 hours of the wiimote standing idle, started dolphin again, and it was down from 4 battery bars to 1 red)
It's certainly no urban myth; Bluetooth still communicates with wiimote as if you were using it like normal... Even after you shut down dolphin. No big deal if you have rechargeable batteries but still a nuisance
