The big advantage of eInk screens is they do not require power to maintain the screen once it's been written (no refresh rate). But you gotta remember that the screen isn't the only thing drawing power. While the Kobo is powered up, the system is still ON... it's just sitting there idle (think: your computer sitting there powered up, but using 0.5% CPU power). The system still needs to be responsive to button presses, so that means either polling or waiting for an interrupt to be triggered.
Then there are numerous other things that will draw small amounts of power, such as refreshing the volatile RAM, keeping the clock running, etc (minor things 'under the hood').
Hope that helps
