right now i have the brightness down to the lowest setting and only have firefox open. i have a 76% charge remaining and the battery meter is telling i have 1:42 left. i have a late 2008 unibody macbook pro. before snow leopard i could consistently get 3 hours of battery life with wifi on and 4 hours with no wifi. after snow leopard i cant get beyond 2 hours even with wifi off and no programs running. has anyone with a late 2008 mbp experienced bad battery life?
