Info 2 core-A7 of OCTA not help save battery life compared to Core-A15?

AS YOU KNOW
P= U x I
If U << then P << / (I not change)
If P << we will save more battery

P/S " If my reasoning is correct, then we will get a new set, it helps achieve better performance, more energy saving. My opinion that we should eliminate the activities of Core-A7"

Hi everyone!
As you know, Samsung S4 chip Octa ownership, including 2 processor: Core-A7 and Core-A15; Core-A15 has a better performance compared to Core-A7 but Core A7 - saving more energy; Core-A7 is used for the conventional process. Core-A15 to speed, used for high-speed process needs.
However, I noticed that the ladder of A7 chip - we owned mV index higher than the ladder of A15. You can easily see the following:

According to my experience, mV lower will save more battery.


I have used many kernel and all the same results. mV of Core-A7 higher than mV of core-A15.

Core-A7 of OCTA not help save battery life compared to Core-A15 ???????????

I'm going to find an explanation....


Pls give me your positive feedback!!!!!

If my reasoning is correct then we can only use core-A15 (Set = 800 Mhz minimum, eliminate activities of Core A7), this setting ensures better performance and power consumption receptors.
