And what an awesome joke it is. Try 14 1/2 hours! Wifi on, bluetooth off, screen at near minimum brightness (using in a brightly lit room, and minimum brightness is all I have ever had it set at and that is too bright for me at night.) Mix of about 6 hours surfing on wifi and the rest video. I was even able to watch 4 full length movies once it was down to 23%. Ran all the way down to 1% before it shut off. After charging for about 8 minutes, it turned on and showed 2% then continued charging and was usable while charging. Gonna try an all video test next.
