You cant compare a 3g phone to 4g phone since 4g is newer and will clearly suck down more battery. But all of this was stated in early reviews and they will have larger batteries out that do not need a larger back cover.
It is well known that 3rd party battery makers lie about their capacity. The stock battery already fills the entire area. You can't get more Amps without either changing the battery chemistry (not happening - LiPo is the best we got right now), or making it bigger. Motorola went with a more efficient processor, and made the battery roughly 33% bigger. That should prove HUGE for battery life. I need to talk to my Verizon store rep. Through work, I currently get a 22% discount on plans (got the TB on one year contract for $250), and something like 25% off on accessories. If I get a 20+% discount on phones that I buy retail, then I'll keep the TB until the Bionic comes out, compare the two, and only sell the TB if the battery is still killing me (if they haven't improved it with software updates, etc).
