You have four options on your screen brightness when you have your AC adapter plugged in. You regularly have three, but the fourth add on is a brighter one. So if you want a brighter screen and have access to an outlet and happen to have your AC adapter handy, then you know what to do. Just press the screen button until you get the brightest screen.
Simply play your PSP on the lowest brightness setting, with either 1 or 0 bars of sound, and you're guaranteed to at least get an extra hour into your gameplay.
simply HOLD DOWN the screen brightness button for 3 seconds and voila, screen off, enjoy your mp3 or internet radio without all the unnecessary battery drainage
