Hey, if I'm using SetCPU on the NS4G with the latest stable Netarchy BFS and a smartass governor and I want to save battery, do I need to have a 'screen off' profile and underclock the CPU a bit? I notice that it slows down waking the phone up, which is a minor nuisance and if I can avoid it because the governor will keep it slow already when not in use, then why not?
Using the "smartass" governor and profiles is not a good idea. The idea of using that governor is that you don't need profiles.
Download Proton Voltage from the market and use the suggested voltages within that app and make it boot everytime on start. It will help you conserve battery.
What exactly are the different settings for I/O scheduler in the Voltage Control app?
I see SIO, BFQ and a few others but no idea what the difference is. SIO seems to give me better battery life.
Thanks!
So I flashed Imnuts' new kernel and i am trying to OC/UV. Using the voltage control app i can get the CPU frequencies and I/O scheduler to stick at boot. However, the governor always resets to ondemand. Is there a fix to the init.d script that would change the governor too? I really like this app, as opposed to No Frills Cpu Control, which runs all the time to apply at boot.
I have a Galaxy S3 running a custom ROM (WICKED), In the past I have been using the tweaked stock kernel with ondemand the the CPU would sleep at appropriate times. I updated to the newer version of the ROM and for some odd reason setting the governor to ondemand on the tweaked stock kernel would keep the CPU awake at all times. The only change I made was that I added a screen off profile set to ondemand with lower than full max clock speed. Luckily the ROM came with a another kernel option (Deviant kernel, OC'able), however several governors such as ondemand, conservative and intellidemand has the same issue; my CPU was an insomniac. Finally I tried using the interactive governor with the custom kernel and the CPU now sleeps as it should within a few moments after the screen turns off.
tl:dr: this issue seems to be less of one pertinent to my phone and more so a misunderstanding on my part how governors decide when to sleep the CPU. Why wasn't my CPU sleeping? Which governors are appropriate for a screen off profile?
I've been reading about some kernel modification staff for couple of days now. I have searched for best kernel governor for Google pixel, there was 2-3 threads and in all of them people stated like "bro you're crazy, don't touch stock sched governor it's the most optimised one for pixel". I was like okay, I won't touch, I get it. But than I saw one thread where users voted for which governors they used, and interactive governor had enormous votes compared to other ones, so I thought there must be the reason for that. After messing up with interactive governor settings, I managed to get about 25-30% more battery life than I had on sched. all this without any noticable decrease in performance. Sched governor rises frequencies so often even if you are just on home screen and simply press empty space, all four CPU cores go to sky at max speed, whereas interactive governor is like quiet intelligent killer who sits and waits for big tasks to go full power. Screenshot below shows my screen on time. Before that, it was somewhere between 3-4 hours. So, any thoughts or links about why I could be wrong and what am I missing - would be very very useful.
Interactive again, this time more optimised.

So other than changing to interactive governor, which settings did you change?

Decreased cpu frequencies a bit, also changed some settings inside the interactive gov. Exkernel manager app also helps a lot with blocking wakelocks. Right now, I have small cores set to sched and big cores set to interactive, I guess this variant also will make a good screen on time and better performance. Anything else is the same as it was on sched governor before
Here are the screenshots
Current Sot is 1:30 so at the zero battery it must be somewhere near 4*1:30=6 hours
I suppose I'll stay with sched+interactive governor
