Well my battery life is a little better after switching to CDMA only but I am not getting too much green in mobile network signal. If I only do some light texting from a full charge with one or two FB checks I was able to last 12 hours before hitting 70%. But once I.get heavy on Facebook, Twitter, and browser I can probably eat through 10% in a half hour-hour. Would doing a another factory reset be worth it? I already did one when I first upgraded ICS but maybe I should do it again? Or is the fact I have a weak 3G network doing it?
