I don't know how much a high capacity battery can help. Someone here in the forums told me they were getting 24 hours out of their stock battery. But they were only using it very little without bluetooth HS's and no real data usage to speak of . . Just my guess, but I would say that two solid hours with a BT HS would probably mean you better have a charging source of some kind handy. I currently have several charging sources so its not an issue all the time, but now I am figuring if I leave out in the morning, and know I won't be home until late, I better plan on having something more than my 680 with me to charge it. Something never an issue with the 650.
