I figured with as many people concerned about the battery life of the Inc4G, it might be good for those of us who have it to share our battery life experiences so far. Though I haven't had the phone long (obviously), I can already say that the battery life is far superior to the Rezound, but not quite as good as the Inc2. Today, for example, my phone came off the charger about 8 hours ago, and I used my phone for GPS for 18 holes of golf this morning. That's a pretty big battery killer, and I am still over 50% battery. Overall I'd day the battery is going to be fine, but not the 30+ hours of my Inc2. EDIT: By the way, the golf GPS app I use (Golfshot) picked up the distance much faster with the Inc4G than it did with the Inc2. There were times I waited 30-45 seconds or more for it to finally lock on the Inc2, but the Inc4G was basically instant. Very impressed with the GPS.
