I've reported previously that it takes about 7 hours use per day to
maintain the battery charge on my ARMini. That's actually quite a lot
of use for a domestic machine. I'm currently letting the battery
level drop to see what happens and how low it will go.
Of course, original BeagleBoards didn't have batteries so always
booted thinking it was 1970 - RComp took the decision to supply ARMini
machines with batteries fitted. I think the opportunist nature of the
machine design means that we can't assume that the design is optimum
for typical RISC OS users' patterns of use.
