When you say "charging in 2 hours" do you just mean the charging light goes off? If so, keep it connected for another two to four hours. It continues to charge past that indicator light going off. Also/or perhaps your USB port on the PC's is going to sleep?
When you say "intensive" how many pages are you reading? Are you fast-forwarding pages much? These readers consume energy on page turns. If you hit, say, 7 to 10K page turns then your battery could be drained. Personally, I think 3K pages in three days is my record, lol.
