Battery Low [Q] Best kernel for Ditto Note 3 rom for Note 2 Android 4.4.2

I have been facing a lot of issues with the battery performance of my phone and have decided to go for a custom kernel. I have encountered the following kernels in my search so far:
1) PERSEUS
2) AGNI
3) NADIA
4) DEVIL

Is there any better option..?

My priority is saving battery alongside performance with no lag.

Any experienced user ...pls help...i would be very grateful
