* I'm not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed (like it did for me...).
* YOU are choosing to make these modifications, and if you point the finger at me for messing up your device, I will laugh at you.
* Your warranty will be void if you tamper with any part of your device / software.

Hi guys! After long searching, I found best settings for balance performance/ battery.

1) Install Oreo firmware 10.3.1.0. I installed over Pie fw after Rom installed.

2) Install IceCold Kernel v.3.5 Oreo. This Kernel have a underclock frequency (300Mhz) and overclock frequencies (1.8 and 2.2). You'll save battery and get best performance when play games.

3) Set darkutil governors for little and big CPU in your Kernel Manager. Set conservative if you don't play games.

4) Turn off ZRAM if you want save more battery.

5) Enjoy.

pS.: Sorry my bad english.

Doesnt 300mhz use same voltage as 600mhz? In that case it doesnt save any battery, just makes device more sluggish.

I dont argue about that. But that maybe because of other things you did. We shouldnt promote things that dont help, so just saying that people shouldnt be using 300mhz, it doesnt help

That's very useful tip bro... thanks...
But this trick won't workout for pie firmware based custom ROM I think

No. Oreo fw is more battery friendly than Pie fw. 300mhz underclock is a plus only. This frequency dont work properly in Pie fw.

Its not about firmware.. Its about cpu architecture and voltage table used in kernels. SOC was designed to run at 600mhz minimum because its most efficient frequency. If you lower voltage at lowest frequency, it starts crashing and can be unstable. And since you cant lower voltage anymore, there is no point using 300mhz frequency, because minimum required voltage is the same as 600mhz, so you only loose speed..

Here it run smooth and stable at 300Mhz.
