This is a great thread to read on tips for saving power http://androidforums.com/samsung-vibrant/138944-how-save-power.html But this is something that people over look, its mentioned in a few places but I think it needs to be promoted more. I'm talking about, well I guess the word for it is conditioning the battery. Basically you drain the battery down till its dead(though in my case I went down to only 5%), turn the phone off and charge back up to full. One thing I noticed right away was how long it took for the phone to recharge. I have not hard data, but my experience up to that point was charging before didn't take that long. But now that I've done this, battery life is great. I've been listening to music for a couple of hours, some light browsing, viewed a youtube video, took a few pictures, and I have background sync on and I have both twitter and facebook installed with notifications set to their shortest time span(15min and 30min respectively). Currently at 8hrs since unplugged and at 61%. Not bad I'd say. I also have rooted my phone and installed the lag fix. I'm not running BH_MAN's cut down rom, I am still running stock.
