init.d script to tweak interactive governor and deadline scheduler for NX785QC8G

init.d script to tweak interactive governor and deadline scheduler for NX785QC8G

ONLY FOR NX785QC8G!!

I wrote this init.d script to tweak the default values of the interactive governor and switch to a tweaked deadline io scheduler. seems to improve responsiveness quite a bit, and battery life is good too. I'm at 34% batt right now with 5 hours screen on time and constant WiFi use. YMMV but feel free to try it for yourself! just place this file in /etc/init.d and change owner and group to root, then chmod 755. here is the code, script file is attached - DON'T FORGET TO REMOVE THE .TXT EXTENSION!!

Code:

#!/system/bin/sh
