Before anyone starts i cannot find a definitive answer.
What are these and how do they work?
And which is the most appropriate for a) battery life and b) performance?
I use faux123's latest kernel
Thanks
Faux himself has said many times that nvidia chipset does not allow schedulers to run because it is set to performance by default and any others added do not have any effect on battery savings, etc. I would provide a reference, but i do not remember the exact thread.

He is talking about scheduler not the governor.

Disregard my comment.
Search google for the different schedulers. There are explainations of every one of them and what they do, somewhere in Xda.
Search and google are your friends.

You obviously didn't search very hard because I had the same questions a few months ago and I found the answer fairly easily.

Voltage control is free I believe. You should also be able to find a free version of SetCPU here on XDA.

if you can get setcpu for free, do it. Its much better than nofrills. You can also under/over volt and set up profiles.

[Q] I/O Scheduler - NOOP or SIO ? I know there has been speculation that this is a negligible difference in overall efficiency, but I have been on SIO and it seems less efficient than NOOP ? Is this something anyone else has experienced ?

NOOP is ideal for solid state devices, like SSD, RAM drives, phones, tablets. Not so good for traditional disk drives.
Having said that I wonder if the difference is noticeable without benchmarking..

Honestly, I doubt you'd notice a huge difference...unless you're very taxing on your phone, or already super familiar with how it runs lol
Which I am both. I use my phone at least 2 hours of solid screen on time a day and I have flashed somewhere in the neighborhood of 20 different ROMs. I like to experiment. I think sio and noop are very similar but I can't quite figure out which one is better
Sent from my SGH-T959 using xda premium
nvm
I prefer sio, it based on deadline
which one do you suggest for s3? which one has the better battery life?
thanks for your answers.

Overclocking. But unless your a ridiculously heavy user... u don't need too on this quad core beast

Of course custom kernels offer undervolting.. which greatly improves battery. Slows the phone down though.. and that is if its stable.

Undervolting doesn't actually slow down the phone, the CPU still runs at the same speeds just on a lower voltage. I have undervolted my s3 by -75mv per step and it is still very stable and runs the same as before, and now my.battery life is amazing

Well...
Dude, i think i should not answer it as you are asking personally from one person....
But heres my opinion->
I tested about 4 Kernels.
And it was strange to see that none was there with 0 problems. Everyone had some or other problem.
My mission was overclocking.
No kernel worked well except Siyah.
So i will only refer Siyah.
About versions, i would choose the latest as it may have more features and less bugs.
So just go for latest.

Jaskaran probably just answered your question but I use siyah v 1.5 beta 4,.so the latest one pretty much. The stock settings of the kernel are good but if.youre looking to tweak and don'tknow what you're doing there's a good.guide in the 2ND post of the official thread

Hello there, I'm using a S3 with stock rom which is modified (crt, brightness and sound levels,) . I wanted to also flash a kernel to improve usability and battery, but nothing extremely conservative. Could someone recommend me a popular and stable one?
Thanks in advance, if you think I should try a different kernel for a different experience, let me know

Hello everyone. So basically i have a question. Is anyone facing lags on cm 10.1 new nightlies? O have a lot of time with this rom, and i must say that 10.0 was much more smoother (at least for me)
On 10.1 even the homepage is choppy... I'm running Pegasusq overclocked 1.7 GHz with deadline scheduler... any advice you would give me?
Best regards

I felt the latest PA ROM was quite laggy too...
Use Siyah kernel and I have a few tips for settings:
--Over clock to 1.5GHz
--use lulzactiveq
--turn gentle fair sleepers off
--set touch boost to 1000Mhz (or more if you want)
--turn android logger off
I also undervolt all frequencies by 75mv.... I do a lot of PC tweaking and you'd be surprised how much that little amount can reduce cpu temps.
Hope it helps. Did for me.

It isn't really noticeably different to stock settings tbh.. (I.e. still not a patch on Samsung). Give it a go and see how you get on. It definitely makes the ROM smoother.

I have read comments from several devs that claim that this makes no difference and that those saying it does are experiencing the placebo effect
Addition: in case you are experiencing scrolling lag in any apps, make sure you have force GPU rendering ticked in developer options!! Absolute necessity in any JellyBean ROM.
