A couple of us have done battery tests with the Glo, around 10% lighting, WiFi off, and gotten around 45-50 hours of reading over an approximate 21 day period... I realize there is some variance based on reading speed, font size, etc., but it's probably not a huge factor in that e-ink far exceeds the performance one might hope for with backlit LCD technology.

I did my test to provide a baseline when others were having battery issues that seemed to end up being due to problems with something(a sleep cover's inner pocket) causing a touch event to be registered just prior to entering sleep mode.

I'm interested that there is such concern regarding exact battery life when it's pretty obvious the battery life on even front lit e-ink will far exceed a backlit LCD based device by typically a factor of 5-10 times or more for most comparisons? Sometimes we get a little hung up on exact data, where the approximate magnitude of the trend is probably more than enough to indicate a course of action. Just another way of looking at it. That said, I wanted to know how many hours when I did my test...
