I've been using mine for about 2 weeks now. On average I can go from 30 to 50 hours without a charge. No GPS, very little wifi, a few videos, and Pandora for a few hours. It improved after every drain and complete charge. Get battery monitor pro to help tell you how much juice is really left. I can usually run for about 12 more hours after the internal sensor has reach 1%. I wish android would give the droidx support for extended batteries.
