battery drain and kernel

I got this rom from about 1 month, before the 14.5 and now the 14.6 and I love it for performance and look. In the last weeks the battery drain is becoming insane so I would want to change kernel, some advices?

I haven't been able to find too many cm based kernels on XDA that have recent updates, but math kids matr1x kernel is pretty good helps out with battery life and has been stable for me.If you find any others let us know.
