Does SetCPU overclocking raise voltage for the CPU ?

    Been wondering this for a few days. Does setCPU raise CPU voltage when it overclocks ?

    Because if it doesn't, then battery life shouldn't be affected.

    In most cases, yes. And underclocking also decreases the voltage. The connection between frequency and voltage is usually controlled by the kernel.

    It doesn't do much on Snapdragon phone kernels because those are usually undervolted anyway, but Droid kernels are often heavily overvolted.
