So is there any conclusion to this thread as to what can cause random massive increases in battery drain?

A week ago I was easily getting 10 hours with VoIP and other things connected. Now I'm suddenly getting 3 hours and it dies. BatteryGraph (and conky) never record more than 5% CPU usage (xorg does occasionally jump to 10-15%) and it happens on 3G and wireless. Any battery grapher that tracks network usage? I'm skeptical its my network that is draining the power. I'll trial by running in offline mode once I charge up the battery (its at 0% after coming off a full night charge 4 hours ago).
