I have the same problem with my Bionic. 4G just drops off, I can feel the battery getting hot, and sometime the screen times out while I'm doing something. I can hold my wife's Samsung Stratosphere and my Bionic side by side and only mine loses signal. I get allot of "no connection" when I try to go to Facebook, and check for updates on Twitter, Gmail, or my other email accounts. It does it no matter where I am, home, work, or otherwise. I've had it like a month and it's a far site better than the old Droid 1 I had. But battery life is like 3 hours of continued use, that's unacceptable. I'm sure Verizon will just say "boohoo" if I ask them to look at it.
