Which debate are you trying to settle?

A) The 800w has worse battery life than the 700wx, 750 and Pro (does anyone dispute that?)
B) The 800w does not meet the advertised battery specs (talk/standby time).
C) The 800w does not have an adequate battery, period.
D) Something else I missed

I'm all for getting another data point, but I don't need an experiment to tell me I'd like more battery life. For now, I just top it off every chance I get and keep the email checking to a minimum.
