yo, i just got hold of my mom's sony t665c and as all the reviews says the battery drains realy really fast. right now in about 1 hour with the back light on, it'll be dead. I was wondering if anyone knows whether if chaning the battery would help? if so if there is any reccommended batteries/sellers of that battery. Cuz right now i only use it for enetertain mainly for ebooks, so i was wondering if it is even worth buying a new battery or some sorta charger for ac. or both.
