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?
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.
