[Q] Different Frequencies at the Same Voltages topic

Hey guys,

Quick question for you all. I was thinking this morning about overclocking and its advantages/disadvantages
and one question in particular erked me.

Say for instance there are two Moto G 2014s. A and B.

Moto A:
@1200mhz
@1200mv

and Moto B:
@1400mhz
@1200mv

Will the battery life be the same as they are at the same MV or will the clock speed effect battery life anyway?

Thanks in advance,

Chris.
