The Bionic has good battery life IMO. Everyone speculates that the Nexus on VZW will be some uber phone but in reality it is the first dual core LTE phone on Verizon's network that they have ever had. It has a far higher chance of having crappy battery life or lower than expected benchmarks than any new phone coming out from Moto now that they've gotten on the TI train.
Very true... and the bottom line is battery technology piqued way before cellphone technology did. So no matter how souped up the phone, if it can't hold the physical size needed for great battery life, there's only so much software can do to help until some new revolutionary battery tech comes out. I would venture to say the Bionic will have the best battery life of all the LTE phones for awhile to come thanks to the good sized battery in it. Though that battery could feasibly fit in the RAZR as well. Until they improve the LTE radios, LTE battery life will continue to be a "problem".
Oh and the Bionic is the first dual core/LTE phone...
