Thanks for your comment, i will extract the modules wifi of my ROM and create a fix STAY TUNED:o
WiFI doesnt work, I tried with Wifi fix of renix and n1kolaa wlan-modules.zip but no solved.
i think this is a normal battery drain. i had this battery drain also with stock rom.
Try Renix kernel 4.0 zram, and send me pm for settings for good battery

Rom: CM12.1 by n1kolaa
Kernel: Renix 4.0 zram...
Nah i assumed you had a custom kernel and you wanted to go back to the kernel that came with the ROM you're using.
To extract the .img simply open up the archive and extract/move the boot.img to wherever you want to extract it eg; sdcard, than fla...
