Op i would love to see a screen shot or picture of your screen showing the time unplugged and percentages breakdown please, because 48 hrs with 50% left just seems dreamy to me. If its true, then its amazing.
I am on my second Droid X. The first one quit ringing. Long sessions with tech service and a trip to the Verizon store, no luck. The new one is fine. I have never had a phone that the battery lasted longer than a day. Other people who use their phone more than I do get 2-3 days on a charge. Not complaining, just keep charging.
