Using that pattern, 6 / 2 = 3 days for DR
Sure, my Cybook lasts entire month because I am a light reader. DR would last several days if used only 1-2 hours each day.
However, note who are early adopters! These are heavy duty super-readers spending several hours per day reading. So using their pattern of say 6 hrs/day, even Sony wouldn't last very long (less than a week I imagine, same as Cybook).
Another way to put it, imagine DR supported 24 hours of active use (reading, flipping pages, etc.) An active busy reader using 6 hrs/day would get a decent 4 days of use. However, a light reader like myself doing only 1 hr/day on average would get almost a full month.
The bottom line is that we expect several days of use on a single charge *EVEN* for the most active users. This is what I am looking for when the 2 modes are implemented.
