Overview: SetCPU is a tool for changing the CPU settings (capable of overclock and underclock) on a rooted Motorola Droid, Nexus One, G1, G2, Samsung Galaxy S, myTouch 4G, or one of many other devices to improve performance or save battery.

SetCPU also allows you to set up profiles to change the CPU speed under certain conditions, such as when the phone is asleep or charging, when the battery level drops below a certain point, or when the phone's temperature is too high. See the screenshots for examples of how you might set up profiles.
