I just got a reader the other day. I let it charge completely before using it... took about an hour to charge though, but I left it plugged in all night. Anyways, at about 10am I started using the reader unplugged... just a few reads of an e-book or two. When I went to work I started reading comics on it, about 250KB a piece comics, took a little bit between screens switches, definitely more than regular text. The thing is, i'd estimate that 30-35 comic page flips drained 1/4 of the battery!!! It was drained by 6pm! Is that normal, is ist just 7500 page turns for text and just 120 page flips for 250KB Jpegs? Or should I exchange this reader for another one?
