Well, I just managed to drain my batter this afternoon, it would be at half and then down 3/4's and then I was playing with the little toggle button and well it killed it, said I needed to charge that I was low.......... so lets see, I have had to small charges in between and have read 4 books with them being on the large side of fonts if at all possible and approximately 3350 pages total of what I have read and am reading at this time..... sure isn't no 7000, is that what they claimed? I think font size has a lot to do with it..... either way, I have it charging in the wall unit and wish it would hurry up.......
