Wold my laptop battery last longer if I turned the graphical settings in my game to low?

When I'm doing stuff on my laptop that requires little power (such as surfing simple websites or word processing), the CPU fan does not spin because the CPU doesn't need much heat displacement at those activity levels. The CPU/GFXU does very little work and so does not use much electricity to achieve those tasks.
When I play a 3d game, the CPU fan gets really noisy. This is because it has to work harder to displace the heat that the CPU produces. The CPU performs more activities which consumes more electricity which creates more heat. If you lower the graphical requirements of the game, the computer has a smaller data set to work with which means it doesn't have to use as much energy to calculate the game which means it uses less electricity to power the laptop.
