4G seems to be a work in progress, from Verizons end to the Hardware manufacturers end.
I guess its a known issue with the Bionic which better be fixed with update or they will take this phone back. Im not an expert but from my expierence with my bionic I think its in the Radio. The phone doesnt switch from 3G to 4G very well you have to toogle airplane mode and if you are in a extended service area you have to put it in 3G only. Really sucks paid all that money for a phone that doesnt work as well as my Thunderbolt battery life included if they dont get a fix to make it at lewast as good as the Thunderbolt there gonna give me something better or Ill sue them lol. Wonder how far Ill get with that?
The droid bionics battery life is way better

i guess it all depends on how you use your phone. I dont just use my phone I abuse it. I mean I have everything turned on I can and trust me battery life on the Bionic is not a whole lot better. The Thunderbolt is rooted on bamf 1.7. Bionic is stock rooted. I got 12hrs out of the Bionic today but I didnt use it like I usually do spent a lot of time in pouch. I guess what Im trying to say if you use your phone your gonna use battery. there is nothing wrong with the battery its how you use it.
