Automatic Brightness
I find it amazing that it's August 2011 and some users still don't know how to use "Automatic Brightness". Most guides even tell users to disable it, and many even assume that the sensor is broken!
But it actually works. What it does is make sure the screen is bright enough and still legible without the user ever touching settings.
To reduce brightness with Automatic Brightness on, switch the phone off, then back on, and unlock it, then the brightness of the screen will be reset based on the current lighting that the sensor picks up. From then on, if the user goes out to a brighter are, the screen will be set to a higher brightness level and will stay that way until the phone is re-unlocked again.
So make a habit of locking/unlocking the phone regularly if you travel between radically dark and radically bright areas often.
