You guys weren't joking. I work right on the pa and me border near Hagerstown, and just today realized that I had no 3g at work cause it was a 4g zone. I absolutely murdered my battery. Literally in under 15 minutes of some surfing and a couple of apps, I lost 10% of my battery life per my widget. Just a wow moment for me. Of, and that 4g is amazingly fast. Like omg fast. That is all. Posting from my Rezound....enjoying the beats.
