That's the one thing I noticed big time and the reason I see why the Batter life just got a lot better with this update. I noticed that my battery would get hotter and hotter because of the various switches between 3g and 4g lte. This was even with WIFI turned on. When the phone does this constant switch between the different bands, it eats up processing power more and more. So I'm noticing a much better consistency in the stablization of 4G, thus, less processing power and better battery life. And because of this, I also notice that the bionic is a lot smoother with transitioning screens. It's not jittery anymore, at least from my perspective. I have over 100 apps installed on it.
