Hi,
if you use ACPI, you can check how many miliWatts/hour remain at:
/proc/acpi/battery/BAT0/state
As an example, I've got right now (batt. fully charged) 35070mWh. Maybe
that way you can check more properly which source is draining most.
Regards,
Jordi

Unfortunatelly I don't know about any such software which can tell you this,
but I was already planning to hack gnome-battery applet to show time elapsed
on battery, so that I can at least mesure how the batery is doing...
