Samsung Galaxy S3
Total noob here. Just rooted my phone, and have little idea of the endless possibilities.
Starting with Setcpu, what are the best profile, main, governor etc. setting I should use on my phone? I don't want to burn my cpu or destroy my phone so all help will be appreciated.
Many thanks

Android newb here, just transferred from iPhone. Changing the clock speed was never an option for iOS, so this is semi-new to me dealing with phones. Whats the best SetCPU profiles for a longer battery life without hindering too much speed?
Thanks :good:
Hello. I have been running CyanogenMod 10.1-10.2 since I got my device back in July, everything has been working great. Bugfixes have been lovely and all that good stuff; however one thing continues to annoy me. I cannot underclock my device properly. Let's say I go into the normal CyanogenMod Performance settings. Then I put my CPU to something like 1024MHz, then I see how the results went over with PerfMon from Chainfire, it will underclock only on Core 0, the rest of the cores still run up to the standard limit, 1890MHz. The only way I can somewhat successfully underclock is by setting my CPU to 594MHz or lower, at which point it will disable all cores except Core 0.
This has been annoying me for a while, I am running the standard CyanogenMod kernel, and recently I tried the Elite Kernel. The only thing the Elite Kernel did was remove the ability to disable the other 3 cores when below 594MHz. (And add the ability to go up to 2.2GHz, but who wants to overclock the Galaxy S4 yet?)
It may be worth mentioning if I try to tweak individual core settings with Tasker, on Core 0 it will let me set a CPU frequency, then if I go in and try to set something on Core 1, it won't have any of the default values for anything, and I enter them manually, then it will give me some errors about not finding the governor I said and stuff like that.
Anyone who knows any way to fix this (Custom kernels, different ROMs (Only for curiosity, I would stick to CyanogenMod anyway), etc) would be greatly appreciated.
Anyone who questions my motives for underclocking, question away. I don't like how my battery life is next to junk when I'm not even touching my phone all day, and the GS4 hardly needs the CPU it has, so I plan to use Tasker to set up a bunch of power saving mechanisms.
I suppose I do have one other question. Will underclocking even benefit me if I can't modify the voltage settings? Are they modified automatically when you're running at lower frequencies? (You would hope so, considering it's kinda a mobile device with a power source that isn't infinite). But if it won't help me without lowering my voltage (and if it isn't modified automatically) is there any good way to do that with a Tasker based setup, so it can be switched instantly whenever I do something? For example, launching a music player. All 4 cores shoot up to 1890MHz (I know they eventually settle down to lower frequencies, but for example's sake), I would rather have it so when I launched the app, Tasker would come in and set my CPU to ~800MHz with only a single core. Everything might slightly lag, but it would work and I would potentially get better battery life while listening to music.
Also, I never tested this on TouchWiz, as I didn't stay on it for more than 30 minutes after I got my device.
I am running the latest CyanogenMod nightly in case it matters (20131002, and it'll be 20131003 tomorrow unless it breaks something)
Thanks in advance to anyone who can possibly help with this. I'm sorry if the post is unorganized, but I hope it's understandable.

Forgive me for my ignorance since I'm on ME7 and unable to flash CM10.x yet, but couldn't you just try different governors instead? On my old phone I was using lulzactive and it gave me great battery life, and you could tweak all the values any way you want for more performance or battery life.
I also remember when I experimented with undervolting and much to my dismay it turns out it made my battery life WORSE because of all the error correcting it was doing.
I get at least a days worth of moderate/heavy use on mine and with how fast it charges I don't really care about battery life but I'm curious how much actual gain you'll get for your efforts
Hi guys. Im new and i need help. I game a lot on my gs3 and usually overclock my device. One thing i noticed is that when i overclock to 1.6mhz to 1.7mhz, it would stay there for like 5 minutes, but then the device gets slow and when i check the frequency it be on 1.0 mhz. I'm using a gs3 i9300 tried both setcpu and no frills. Im on latest siyah kernel running stock samsung rom. Thank you very much. (did i do this post right, is this the right section?)
Hello, could anyone please tell me what some good settings on set cpu , for a rooted T-Mobile Alcatel one touch fierce would be ,
Thanks...

I don't have the same phone as you but Intellidemand / Zen (governor / schedular) seem to be a winning combination for performance vs battery life but it will probably vary from ROM to ROM and supposes the kernel you've installed supports it.
Perhaps you could say what you're hoping to achieve? Max battery life (slow the CPU down) vs performance.

Oh, sorry, I'm hoping to max battery life and maybe speed up the phones performance, (if possible) I got the paid app from the market even though we don't have the same phone but if you could share your settings I guess its better than the factory settings
Once again thank you, and sorry I forgot to put what I was hoping to achieve in my original post

You have to choose. Best performance or best battery. If you want the best compromise then like I said, Intellidemand and zen if your kernel supports them.
I'm not sharing settings as we have different phones and different Kernels so it'd be pointless.
I used to have lots of profiles for various times of day, screen on, screen off etc but now I pretty have two. One for general (min and max are whatever the kernel allows) and a profile for low battery where it max's the CPU at 30-50% whatever is max and changes to the conservative governor.

Ok see didn't know that, so I would choose performance over battery life then I am new to this and don't want to brick my phone I bricked a rooted android trying to change a boot animation using root explorer so just trying to be careful, also if you could help me with the "MHz" settings it would be great to the choices are 497, 754 ,988 & 1209 that would be great to
I have all the good root apps titanium backup pro root explorer pro and a lot others, but lol I just don't know how to use them yet...any knowledge on a boot animation logo change would be appreciated to I learned a little after I bricked ny phone I know that I didn't put it in the right folder but every post I read people say it bricked their phone so maybe I should staw away from it until I am a little bit more experienced idk.
But for cpu performance would be what I would choose
Thanks again..
Not sure if this is the right place.
Basically, Ive been looking around for a way to under clock/over clock the umi z device. I have tried many apps, that say they will overclock and under clock and also ones that say they change the CPU governor. Ive had no luck on this phone. No matter what CPU governor I select it stays on interactive, no matter what minimum and maximum core speeds I select they keep changing and going on/off on their own, and basically anything related to CPU /GPU speed are completely unchangeable. There isnt any custom kernels for this phone, so I was wondering if anyone with the right knowledge would atleast know if it is worth trying and even possible to create a custom kernel for this umi z that allows CPU control. If so I would gladly try myself but I'm not the smartest and dont wanna waste a tonne of time to realize it never would have worked anyway. ALL help is appreciated and politeness even more so, thank you.
