EDIT: Oh, it seems there is a bug that affects battery life. I didn't know about it.
this is true. i don't mind buying a new battery if it would work but sadly i don't think it is the case. even if i forget to charge a day it would just die and needed a reset. i really was becoming agitated and my birthday was in december so my husband bought a new PRS-600 as a gift. we both realized we should not have sent it for an update. sony seems to be replacing it with some refurbished units and i called them many times but i am not able to get any response from them. i sent it in november so may be that is the reason i am out of luck
