Looking for Kernel (I9505 Resurrection Remix 5.5.7)

A

AC Question

I just installed RR 5.5.7 on my S4 (jflte) yesterday and so far it has been absolutely amazing, except for the fact that battery life isn't as good as it was with CM12.1.

I had the voltages turned down quite a bit in Cyanogenmod, my SoC seems to be able to tolerate a lot of undervolting, so I was getting amazing battery life. I'd love to do this in Resurrection Remix, but unfortunately the Kernel doesn't support voltage tweaks.

Can someone recommend a Kernel that would work? I have no idea where to even start looking.
