Anyone else notice Auto screen brightness kills battery faster than fixed?

im pretty sure its because the light sensor is always polling. that eats battery, ironic that it supposed to SAVE battery

I'm not sure what the net effect on battery life is (reduced brightness vs polling drain), but to me, I also like the auto-dimming just because I prefer to have it a bit dimmer in dark environments.
