Your units are incorrect. I think you meant to measure your battery
capacity in watt hours (watts times hours, which is a unit of energy),
and to calculate the energy usage as 8 watts. (watts = energy / time,
using joules and seconds.)

What percentage of the total power is used by the CPU? How
significant is that extra 10W for the CPU?
