So pretty much the Battery life on my DX with stock GB was sucking after the update. Came here as I always do looking for advice on what to do. Very simple action really, One of our awesome Forum Peeps said to Factory reset the phone. Low and behold battery life is amazingly better. This time yesterday my battery was down to 30%, Today with the same usage 60%. This may or may not work for everyone. But it worked for me. Simple things like this make me extremely happy. This site is an Invaluable source of information and People. Cant remember the last time I even called VZW Tech support. Shout out and Thanks to "quickaudi" for throwing some advice my way. When in doubt "start fresh and clean".
