I have never really tested, but it I am pretty sure that in the past it has sat with a page left on the display for a few weeks and I didn't notice that the battery was drained. I'll do that now to verify.
BTW, on mine I can completely make the screen go blank and apparently shut it fully down by holding the power switch for maybe 5 seconds. When I flip the switch again it comes back where it was. That is a Kindle 3 though.
I'll check once more, just to be sure. The word seems to be that sleep vs off shouldn't matter. Active may drain the battery if not in airplane mode (mine was) or backlighting is on (mine was, then I switched it off, w/o noticing major difference). But frankly, this is hair splitting -- these devices consume very little. The more important question is whether they have bike touring uses (other than carrying guide books in electronic format).
