I've been using this device for over a week...and I am noticing a very disturbing trend. I know a lot has been made about the battery. And what's weird is that for the purposes of data, it's not *too* bad. But take or make phone calls and all of a sudden you're in the drink. I also notice periods without a signal in the stats, which is something I haven't had an issue with on the RAZR. It makes me wonder if the 4G radio is no less efficient than other devices but the actual phone radio is the battery hog here. To put it in perspective, I took a 30 minute call on the Nexus. Battery dropped by 25%. It took a 2 hour conference call on the RAZR to experience the same battery drop.
