I took a look at some of the options but there were just too many and I have no clue whether the numbers were "good" or "bad". Can anyone shed some light on their governor settings if they tweaked it?
I'm currently using the perseus kernel alpha 27.4. with Jedi X6 rom.
I personally wouldnt mess with it...just leave it on stock...if anything you may want to consider flashing one of the 2 kernels. .both great...overclock to 1704 and set the gpu to 640 using the stweaks app will help adjust these gpu settings...and romtool box is my favirite though...then once you learn and research. .maybe undervolting in the future...but for niw just stick with these setting..wont kill tour battery..and is very stable and excellent battery performance. ..good luck

ok, i searched for the problem i had but couldnt find anything relevant. i hope someone can direct me to it, if there is any already, or give me an answer,
i downloaded Setcpu and ive seen most of people using "conservative" scaling for better battery life, but i dont see that option in the app. i just see ondemand, userspace and performance.
any idea if im doing something wrong?
and also i would appreciate if someone can tell me the settings for longer battery life? wanted to try it but didnt understand that much.
thanks.
btw im using virus rom rc3 with stock kernel.
The governors are kernel specific- if the kernel doesn't support it, it won't show up as an option. In your case, conservative scaling is not supported by the kernel you are using.

oh ok. now i got it. thanks for the info.
Both Netarchy and Kings kernels have "conservative" governors on them. One of the top ways to conserve battery is to make a profile setting for Screen Off where you set the min and max freq to the lowest possible setting. For me though I can go to 128 Mhz, I get too much lag on wake-up and therefore set to 384. Your phone may do better.
Someone also made a thread that describes the advanced settings. Tweaking those can also improve battery life as well.

appreciate it.. thanks ..
I am new to the setcpu app I am wondering how do I know how much frequency my min and max should be to help my phone out more. Can anyone help me on that plz?

It will depend on which ROM and kernel you're running, but generally, overclocking doesn't do much good for you. I do however run my Main Max @ 1113 and Min @ 245. I then have a profile set for Screen Off Max @ 245, Min @ 245. This has helped a lot with battery life. This is on CM6.1.1 and the SBC stock kernel.
Also, there are the Scaling options. They will vary based on the kernel you're using. Generally, their names speak for themselves, so pick appropriately. I use Interactive when available, or Ondemand as a second choice. If you choose Performance, you will stay clocked at the highest speed until over ridden by a profile, so don't bother with that one unless it's for testing only.
One thing to think about is that Setcpu doesn't play well with HAVS, so if you're running a kernel with that built in, they will be fighting each other.
Also, if you're running a stock based rom with a stock kernel, you will need to disable Perflock if you want Setcpu to be able to really do it's job. So, while in Setcpu, tap Menu > Perflock Disbaler and attempt to disable perflock. Once it is successful, pick set on boot and close that window. Now Setcpu can work properly and you can start saving battery.
If you're primary goal is to get amazing battery life, I highly reccommend you try some of the new SBC kernels that have trickle charging built in. That's what I've been using since they came out, and it is amazing what a little tweak can do for you. SBC Kernel Thread
Whats up guys? I have a question about using the Set CPU app.
Is it really worth it to use this app? Will it actually make an improvement in my battery life?
I don't want to use this app to speed up my phone, but to make it better on battery life.
I know you can set up profiles, but I'm not sure on what good setting would be to use. Can anyone give me some insight on this?
Also I'm running the latest version on MIUI and the Tiamat kernel.
P.S. Is there better kernels to be used then Tiamat?
Thanks in advance.

maybe it's just me, but am getting better bat life with the stock kernal. I ran the tiamat for a few days, switched back and it was obvious to me.
With Tiamat the default governor is smartass, which has a built in setting for when the screen is off, that only lets the phone see a max of 368640, which will save on battery life and does.
Now if you want to get into using your own profiles then an app such as Setcpu can be helpful.
I have been using this and this in place of Setcpu. It's a little faster reacting to the changes form screen off to on. Just another option.
I like the Tiamat Kernels as well as JD's Kernels. They both work well with Miui, at least on my phone anyway.
I've used Set CPU for awhile, but then got away from it. I'm back on it now since MIUI doesn't have a built in OC. I would try the two PacerguyDon suggested. I have used the andrev_oc it is fine. The second one appears to have more functions than Set CPU. Set CPU doesn't allow you to under volt if that is what you are looking for.
I saw that Set CPU is $0.99 on Amazon, if you want it. However, I would try the other two for free and donate to the one you like best.
I have been using JD's Kernel the last few days and it seems to provide better battery life than stock. I originally tried using the Smartass govenor, but had to go back to On Demand. The Smartass was causing screen wake delay when receiving a call.
I stole this from another PacerguyDon's post and it breaks down the different govenors found in most OC apps.
Govenors
Set CPU is free for XDA members. It also does allow undervolting according to their post.

I just rooted my s3 and would like to overclock it a little. Just wondering what the best settings would be and if Set cpu is indeed the best app for this. Thanks in advance and I apologize in advance if I'm in the wrong section.
First you're going to need to flash a kernel that has overclocking capabilities. I highly recommend ktoonsez however if you are not familiar with extreme customization, then faux or lean kernel are better suggestions

I also suggest that whatever app you do use (I use SetCPU as well but they all generally work the same), DO NOT SET ON BOOT.
Since you aren't quite sure you know what you are doing yet, if you input a wrong value or your CPU can't handle "that high" an overclock or your CPU cannot handle "that low" of an undervolt and have it Set On Boot, you will be stuck and have to Nandroid back.
Once you know if certain values work for you, then use Set On Boot.
Does anyone have any recommended kernel settings they'd like to share? I've been changing things around a little but I'm too afraid to make any big differences as I don't want to ruin anything. Any recommended GPU clock settings would also be appreciated!
Also, I see people mentioning they're overclocking their phone a lot. Does overclocking on this phone mean it constantly stays overclocked until you change the settings back or does it change frequencies as needed to a maximum frequency that you set?

Hey When you OC lets say to 1800mhz . That means your proccesor can Amp up to 1800 mhz if needed. Your phone will always idle when its a sleep. My setting are 100mhz UC and 1800mhz OC. Gpu is also Oc to 640mhz. I use pegasusq for governor and cfq or zen for scheduler. I also use eco mode . I get very good battery life and performance.
Also...what apps are you guy using for this? Seems most use trickster... Wondering if anyone has experience with others.

I would use whatever the developer of your rom/kernel recommends (which is Trickster most of the time)
Anyone know what eco mode does? I've been looking it up but all I've been getting is this guy's kernel that he named 'eco'
Also, for anyone reading this thread with a similar question to mine I'd heavily recommend using Zen over CFQ as a scheduler because it's much smoother and no jitters/stutters (at least in my experience)
Sent from my SGH-I317
I'm curious what Eco does as well. Tried looking it up, but didn't find anything useful.
Trying out Zen...been getting some annoying hangups and jitters with this kernal. UC 100 OC 1704. And FYI...I've used the stock clocks and still got the same lag and lockups and screen freezes. Also tried on demand gov.
Could it be that ZRAM is enabled? Not quite sure the benefits of it.

Do you have eco mode enabled? Also, maybe you should look into Seeder. It sounds like it's perfect for the kind of problems you're having. Or you could change your minimum voltage from 100 to 200, I heard 100 can be kind of buggy sometimes
