I gotta say, I'm loving the 'bolt but it is tempermental. I've run it stock, rooted, three diff krnls and two diff ROMs, messed with all the settings, etc. Batt life deff better rooted but still, haven't changed a single setting on my phone in the last week and with very consistent usage patterns, some days I've made it all day with juice to spare on the stock batt and then this morning I lost 13% in under ten mins of browsing on WiFi lol... I am convinced there are either hardware build consistency issues with the production of this phone and/or serious LTE kinks to be worked out still. My 'bolt actually gets better battery on fixed LTE than LTE/3G mode, and I'm in NYC where presumably the LTE saturation is pretty thick so there should be minimal hunting around for signal. Who knows...
