I think the device has more issues than a battery....
Per UnWiredView.com .....
Of course, Motorola may have (wisely) decided to throw some other updated hardware bits in there as well, we just don’t know at this point.
I ususally always buy the current "top-of-the-line" phone when I get a new phone.... and I follow the new phones being released constantly. However, I always wait until I have an upgrade available before getting a new phone. Also, sometimes waiting an additional couple of months, the price will come down more due to some special deal or sale. This is mostly because, there's no way I can justify (in my mind) spending $500 to $700 on a phone.
My guess is the constant increase in hardware specs eventually will begin to slow. Then the release of new phones will start slowing also.
My next upgrade comes around this coming March. So I'm hoping the new 4G radios that are smaller, faster, and cooler running will be available by then, or at least soon after. I'm patient, I can wait.
Best of luck to all of us.....
