Battery will get better, you have two things going against you, that just need time. New battery needs "broken in", and Gingerbread needs a couple of days to figure out your usage. Just give it a couple of days.
Hey gang. My Rezound arrives tomorrow. Took advantage of the $50 deal online. Was waiting to get a Razr Max but $50 was too good to pass. My husband paid full price two months ago for a Rezound and put the extended battery on it right away. My goal will be to try and get away with not putting the extended on. I do value a slimmer profile.
