I have always had a problem on NRG roms where the button on my headset wouldn't hang up and I had to use the phone buttons to actually hang up. Apparently some other channel is hanging open as well.
I will search around to look for better BT settings -anybody have a good place to start before I do?
Off to bed now...

More info:
While the current drain dropped dramatically for a while after shutting the headset down, it did creep back up to 250 - 300 until I turned off BT. Now it seems to run from 59 - 100 mA until it spikes up to do something. I don't know what "normal" is, but this seems better.
So now, I am sitting at my desk with it plugged in USB and the phone in USB drive mode. The screen is dim but on. The Batt is at 96%, the charge current is 176mA and the drain is 184mA. WTF?
Swapped to ActiveSync mode - same numbers.
Swapped to a cable rated for USB 2.0 = charging current jumped to 431 mA! Who'd a thunk it...
Swapped to HTC AC adapter on USB 2.0 cable = charging jumped to 770 mA but then dropped down to around 460 (probably because the batt is close to full...)
So; learned a bit about cables today, but still searching for an answer on the BT issues...
