This is a similar post I made elsewhere about the review:
AnandTech - Motorola Droid Bionic Review - Dual Core with 4G LTE
They finally did a complete review. According to the review, overall the Bionic has the best battery life of all the other LTE phones if you add them up. In this order:
TBolt (shocker, right? lol)
Charge (Tbolt edges it by about an hour)
Biggest advantages for the Bionic's battery life? Wifi web browsing and talk time. Talk time is a HUGE difference. Everywhere else its about the same. And this may be a shocker to some ppl....it seems to do fine vs. the GS2 in battery life too. Take away LTE scores and its a tie score for overall battery life. (the GS2 on the charts is the international version...no LTE)
So if you have a Bionic, it should have decent battery life, the best for an LTE phone. If you're coming from a 3G phone, LTE is a battery drain. If coming from another LTE phone, it should be better than what you had overall. And a few things I get from this review: the Bionic isnt getting enough props for what it does well....and the OMAP 4 is no slouch, even with its 'measly', 'outdated' 1Ghz cpu...lol .
