The equation for CMOS switching power (as opposed to leakage power) is capacitance * voltage^2 * frequency but the voltage limits the clock frequency. The exact scaling of maximum clock frequency with voltage depends on the circuit and the process, but from taking a glance at the voltage tables it looks like the main cores in current Snapdragons are generally running in the 0.8-1.2v range across their entire frequency range.
