SetCPU [For Root Users] 2.2.4

SetCPU's wide feature set make it useful to beginners and enthusiasts alike. Accelerate your processor to unleash your phone's multitasking potential, or dial your CPU's speed down to save battery.
SetCPU also includes a "voltage control" menu, for use with certain devices with custom kernels that support it, to control undervolting to save even more battery. Keep in mind that undervolting is only available for certain kernels.
Have an HTC Sense device with a stock ROM or kernel? If you are having trouble getting your settings to "stick," press Menu > Disable Perflock. You still have to be rooted.
Galaxy S devices: conservative scaling is recommended where it is used by default (ondemand on the Nexus S and Galaxy S II). There are issues with Galaxy S kernels that may result in crashes if some other scaling governors are used, or if the sleep profile "max" value is set too low.
