Yeah, that's true. So far it looks like a reboot is mostly equal to a
night-long idle consumption.
To me at least. 44 reboots and 60 nights, considering a difference in
how old a battery is, could
very well be the case. I also take a bit into account battery heat
dissipation (in the case of 44 consecutive reboot).

So, I would guess that leaving it on in offline is better than turning
it off and than on during the night (it's faster to
switch between offline/online than actually rebooting).
But rebooting ensures and memory leak gets a workaround. oh well..
