It is difficult to speak about benchmark, as soon as we are talking
about idle power. I think the first step evaluation could be made with
vendor provided data, as it mostly depends on hardware. If vendor speaks
about 2 hours on battery, then there is quite small probability to get
much out of that system, as it looks mostly positioned as desktop and
may have many desktop components. And opposite, system declaring 9 hours
must support a lot of different power-saving technologies to reach it.
