Please share
1. your favorite governor (do you use any different governor on different profiles?)
2. your voltage parameters
3. Your benchmark using quadrant
Thanks
No one wants to play?
Maybe like me, they have no idea what you are talking about
What is a governor?
What voltage do you mean?
My quadrant score is 3900 ish
Thanks for the reply, I don't think I'm good enough to explain but, in a nutshell,
A governor is a a piece of code in the kernel that decides on the cpu speed. each kernel has multiple governors
voltage is where you can decide what voltage is delivered to your cpu at certain frequency. undervoltage will usually help you save battery. we have to pay attention not to go too low or it phone will freeze
download setcpu it will all become clearer
I will give this another bump before letting it die
Even I would be intrested in sharing this
currently I am using CF root with ondemand and its working all good
FM kernel with interactive. I find my phone snappier with this governor. I liked it the most with smartassv2 on Abysssomething (don't remember now) kernel, but too many teething problems with this one, had to revert to FM. I'll give it another shot soon though.

Do you use any additional profiles with Interactive?
Nope, I like the way it is.

Have you tried InteractiveX? Or, better yet, know the differences between the two? I am currently using smartassv2, FM kernel and have no complaints but would be interested if there was something a bit snappier when opening an app (I still get a bit of lag if I quickly select an app after unlocking the phone).
Yes, I've tried InteractiveX and OndemandX - they're both absolute rubbish (at least from my point of view). Both responsiveness and benchmark results were dismal (2800-3300 quadrant advanced). These are governors for anally retentive battery life lovers. Nothing wrong with that itself but beats the purpose when buying state of the art top shelf performance smartphone IMO.
Good to know. I appreciate the advice. Does that mean you also tried smartassv2 with the FM kernel? Any discernible difference between that and interactive, if you have? And sorry for all the questions but it saves me the trouble of trying them!
I just flashed the 1.3 FM a moment ago. Now running 100-1704 smartassv2, haven't played with voltages yet. Responsiveness in terms of screen scolling, lags & stutters seems better than 200-1400 interactive. Performance in Quadrant Advanced and Nenamark2 seems a tiny bit worse (but I don't really care about that, I use benchmarks only to roughly estimate, smoothness is what I'm after). I can't give you direct sources because I don't remember, but having spent several hours digging last weekend I concluded that for people who put performance slighly over battery life governors to be considered are interactive, smartass(v2), savagedzed and performance. Funny enough - I'm getting consistently worse benchmarks on performance governor on all kernels. I wonder why?
Thanks again. I will play around with some of the governors and settings to find the right fit. I think I will try savagedzen next but I am pretty happy with smartassv2 and may just stick with it.

Smartassv2 and vr. After reading a bit about it they seem to be the best for performance and balanced battery life.
i share with you my SetCPU config, voltage ...
it's very stable for me. It's not performance oriented but battery friendly.
what you think ?
EDIT : I use AbyssNote Kernel 1.2
I'm getting nice results here on FM Kernel 1.3. 1704mHz (1375mV) - 100mHz (775mV), lulzactive governor. 5000-5872 in Quadrant advanced, 32-35 in Nenamark2. Battery life good with low to med usage, poor when playing games, running satnav etc. - hardly a surprise We'll see about stability but so far so good.
This thread is finally picking off ! thank you all
I am currently on FM 1.3 and preferring lulzactive
I don't use any over clocking I guess I don't dare. is it safe?
I think i'm pretty aggressive with under voltage i'm running 1175mv at 1400mhz and 775mv at 200mhz. For some reason my phone freezes any time I use the 100mhz no matter the voltage .
Can you share the whole voltage for a comparison ?
with all this I can hardly get a full day of use with my battery but I guess I'm a pretty heavy on usage. no gaming or anything extensive but wifi-browsing-emails-3g-bluetooth all day

I read on some other kernel thread that Samsung's implementation of the 100mhz step is incomplete/buggy. That's probably why it doesn't work properly.
The first thing that comes to our mind is overclocking for a better performance and underclocking for better battery life.
I tell you what, you might get bettery battery life by underclocking. But a big problem starts here:crying:,
The processors are tested vigorously and out of the box you get the sweet frequency.
UNDERCLOCKING: Sweet frequency for DEEP SLEEP is 200MHZ.
If you think you can get a better battery life by making it sleep in 100MHZ your are completely wrong, It takes more voltage operating at 100MHZ and thus further drain.
Overclocking: Don't do it, Games like Real racing 3, NFS most wanted plays without a lag, The MALI-400 and Dual core CPU does a great job. So u really don't need overclocking.
CPU GOVERNERS: Don't try switching between CPU Governor's often. By default it comes with ONDEMAND and that is good enough for multi tasking and it is good as a daily driver. ONDEMANDX is a slightly better one. Both of does a pretty good job. So i suggest you stick with these two if you want the phone to working like a S2:good:
Hit the thanks button if you like my suggestion :good:
Can you guys give me the best GPU govenor for any kind of rom? thanks!

That'll depend on what you need your phone for.
If you want all your cores to run at max speed thereby maximizing performance on games and browsing pick the performance kernel.
Otherwise for normal usage just pick the interactive governer.
There's a lot of governors available but these 2 are the only ones that are important and actually useful. Major kernel developers only give support to these 2 governors as they are the most useful when compared to others.
Dont use any battery saving governer. Trust me, your phone will slow down and make it unusable.
Hope this helps!
Best for what?
Governors are built into the kernel, so if you want choices, you'll have to flash a kernel that has those choices. Some are for high performance. Some are for saving battery. And then there's ones in between. Some might work better if you underclock or undervolt to save battery. Some might work better if you run only 2 cores. Some have better wake-up speed from sleep. "Best" depends on what you plan to do with your phone.
Don't forget about profiles either. For example, I've been playing around with HellsCore kernel and HellsCore Manager. You can create profiles depending on what you're doing. Like, if you're plugged in and playing a game, set it for max performance. If you need it to last as long as possible, limit the max clock speed, run only 2 cores, and use a battery saving governor. With HellsCore Manager you can even mix it up; Performance or normal until battery hits 50% (or whatever), and then switches to a battery saving profile. Pretty nifty.
Hi
I have my G4 unlocked and rooted on 10C, and thought I would try some Kernel Setting experiments using Trickster.
Stock settings use Interactive.
So I tried Userspace but seems that Userspace sets the clock speed to full nearly 90% of the time for me.
So I decided to give Ondemand and read ahead 1024 CFQ a try.
Maybe a placebo? But watching the cpu clock speeds, it doesn't seem to hang up at 1248 like it does in Interactive and drops much quicker back to 384, but equally ramps up quicker too.
I seem to get less battery drain when browsing instead of Interactive 512 CFQ (Stock setting) after a few days testing.
I know very little about kernels on Android, but thought I would share my findings if anyone is interested.
damn i hope root will come fast, i need to have conservative govenor, as it the only one that plays ppsspp tekken well.
the major isue I see is the actual hotplug that keeps all cores always on.
That is pretty strange...LG's devs must be sleeping while our cores are not
Didn't find Conservative in the options. Only Interactive, Userspace, Ondemand, Powersave, & Performance.
Haven't tried Powersave yet though?

I wouldn't play with actual governors and let them at their default value until we have a custom kernel.
Thanks, but I am still finding Ondemand seems to give me less battery drain under use such as web browsing.
Personally, I am really enjoying zzmoove ("relax" profile) on Boeffla kernel. I can't really seem to find another governor that can give me good battery life with such a minimal impact on speed.
Got anything better? Bonus points for your favorite I/O scheduler/readahead buffer settings!
Currently I'm liking IntelliMM (sometimes not so fluent) and SmartMax + SmartMax EPS (tiny bit less fluent)
Best would be to get CPU Spy (2.0), use each governor for 2 days and see which one spends the most time on low frequencies. Also, I noticed schedulers also impact performance, so try tripndroid / zen / fiops also.
Zzmove Battery plus profile, Smartmax , InteliMM and Franco's Conservative(not standard conservative)
except for zzmove i tune myself just a lil all the other governors.
i m aiming for decent battery life( between 5 and 6 hours SOT) with good performance.( i dont underclock my cpu lower than 1953 and my gpu lower than 462)
for Gpu governor i love Simple_ondemand . and for schedulers i prefer FIOPS
