Suggest you give it a little bit of time. I was one of the crazies who set my alarm for 4:00 a.m. on Oct 8th and ordered the phone the day it became available. Battery life out of the box was absolutely horrible. Like gcianc recommended, switching the phone to CDMA only helps (Settings - All Settings - Personal - Phone - Network tab . . .) but you'll start to see battery life improvements over the weeks to come.

I went from needing to charge every day to now going several days before I consider putting it on the charger. Others may argue but I attribute most of my life gain to cycling the battery up and down a few times before full performance is seen. Haven't installed any other cabs that would've affected it.
