A very nice work, tompe. Your results show that cosumption does not seem to have changed, at least with epub.
I am using 1.5, the prc version, and things do not seem to match up with previous version battery consumption.
Whatever I do (I do try to read, but I can't read for hours every day, I have to work too), it looks like I lose about 10% of the battery per day. With the previous version the battery lasted about 3-4 books, now I wouldn't bet on it.
It could be that the battery is deteriorating, after a year and a half, what with loading it while it is not really dead.
Having seen your results I do not understand what they did to lose more than half of the battery life, from the first version.
I do not know, it almost looks like that every time the device is booted it drains the battery a lot.
