My Rezound has done this twice now where it has frozen up, and I've had to remove the battery. When I've replaced the battery, the power button at the top will do nothing. I've had to plug it in for it to turn back on and function. The battery was not drained either, and had at least 50% charge to it. I have had my phone just under 1 year.
Anyone else? Should I bring it in under Warranty, as I don't have much time left for my one year mark?
