7 hours a day?! That's almost the entire work day, that's baffling to me. Between grad school and two jobs, 3 is easily plenty, though I plug it in at night with enough to spare to push closer to 4 I'm sure. Motorola does have great build quality and terrific radios, though I absolutely wouldn't say legendary. Again, I've had the RAZR, loved it, good looking display, much sturdier than most my buddies iPhone 4's. But you don't have any idea how much better the competition is until you experience it; the HTC One X+ is, IMHO, the best phone of last year. Even the GS3, while plastic, is a sturdy phone with a substantially better display, camera, and performance (parents have the MAXX HD & GS3, so I compared them side-by-side extensively).
So, sure, if you're new to the smartphone game or haven't shopped around a bit, the RAZR HD MAXX seems pretty great, but it's just outclassed by both Samsung's and HTC's offerings. Again, the RAZR line is mediocre, excelling with battery and call radios but falling very short with camera quality, display (good, not great) and all around performance.
A battery just doesn't do it for me, especially in the days of the GS4, HTC One, Xperia Z, Nexus 4, or Droid DNA. If I were still on Verizon, I'd grab the DNA or GNex before the RAZR HD.
Side note: I am still in absolute awe someone could use 7 hours of on screen time in a single day. I assume phones have to be a big part of your profession...
