Need help in choosing the right kernel topic

Guys, I have a moto g xt1033. I installed cm11 latest build with gapps and it was running fine, but was consuming too much power, so I decided to install a custom kernel. I tried phantom, xperience and Donkey Kong kernels, and all of them failed to load WiFi, otherwise, it's running very well. In the WiFi menu, it tells, "Turning on WiFi". I even tried clean wipes and installs. Can anyone help? I need a custom kernel for saving battery!
