That reminds me... Q12 of the BATTERY-FAQ does not mention a
difference in current whether USB connected or not. This could
indicate that USB connect hardly matters. However, I have noticed that
when I keep my R20 on a charger and USB the unit gets (slightly)
hotter, while without USB it stays cool for longer periods of time.
This would indicate that USB connect _does_ make a relevant difference
in power consumption.
Is this the right conclusion?
