So I've been searching the forums for a good thread on optimizing setcpu for specifically the Mytouch 4G. I couldn't find one so after i read up on it i created this profile. The tweaks that I've found make this run very fast and gets me easily 18 hours of battery life, and that is with moderate usage. These setting should work for most if not all devices. I don't get any real noticeable lag even when turning the screen on. I'm Using SetCPU 2.1.0 on a Grankin01 Kernel on a Stock ROM, and I'm also using "Autokiller Memory Optimizer" using moderate preset. Hopefully people will post there profiles anyway here it is.
Here is the thread for the Kernel I'm usinghttp://forum.xda-developers.com/showthread.php?t=876848
and here is a link for setcpu basics.

Alright here are my most recent setting I've been running.
I get around 20 hours of battery life on my phone with moderate use my set CPU settings are
Overclocked to 1.5 ghz minimum 245 ghz
Battery below 30% Max 1 ghz min 245 ghz
Screen off max 245 ghz min 245 ghz
Latest Cyanogen mod Alpha 7.0
I use max 1113 min 245 scaling on demand...screen off min 245 max 350
MT4G + CM7
Pretty sure this is in the wrong place. I guess you read up on everything except where would an appropriate place to post this be.

louie i dont know what to make of your preset here... Either you are running your phone incredibly slowly or you have forgotten a 0 on the end and are crazy OCing it...
Have mine set at 76800-1113600 on demand and I demand a lot and average about 8hrs. CM7, zinx kernel,with superpower.
I've been trying to get profiles and triggers down except I use CPU tuner inserted of setcpu. Is it possible to over clock yet still save battery? I doubt that somehow lol. If anyone can post full settings that save battery but still runs well I'd appreciate it. Ill copy one of you guys.
Questions though. What is all the governor stuff like performance, conservative, on demand, etc? What are the thresholds? What are the min max standards? Like if I have 300 and 1500, which does it user and why? Those are the only things I can't grasp

Check out this link it has all you'll need to know http://androidforums.com/evo-4g-all-things-root/210253-setcpu-guide.html
What you want is your device to throttle based on the load being put on it. When you aren't doing much i.e. reading a text it should be clocked at 245760 for example because that's not a demanding task. and versely when you play a graphics intensive app or something, it should use just over the maximum amount of cpu power needed to run the app so the app runs smooth. but wont waste battery by overclocking to 1708800 when only a speed of 1017600 is needed. For this i use "conservative" on SetCPU because it will allow more customization.
My advanced settings for SetCPU are as follow. i haven't use CPU Tuner but hopefully it's similar.
Sample Rate you want kinda low 200000 is what i have and i don't get much if any lag.
Up Threshold is at what percentage of processor usage that the clock speed is increased. for me its set to 60. in other words at 60% load on the processor it will start to increase the clock speed.
Down Threshold is the load percentage where the clock speed will be reduced. i have mine set to 33.
Ignore Nice Load will just ignore nice processes. This includes system i believe. i have mine set to 0.
Grabbed this from a mac forum but it should apply.
"A process's priority is determined with a complex formula that includes what the process is doing and how much CPU time the process has already consumed. A special number, called the nice number or simply the nice, biases this calculation: the lower a process's nice number, the higher its priority, and the more likely that it will be run."
Frequency Step is how much of a jump the CPU will take to meet the load. mine is set low, (12) because most processes and apps wont need a whole lot of boost to run smoothly. For my device on average it will be under 768000 which is what you want and is where the battery saving really comes in. Because the CPU is under-clocked most the time its using a lot less battery but is still running everything smoothly.
A lot of people set there devices to ondemand because it's, "very responsive." although true its responsiveness comes from big steps in clock speed as opposed to the small ones that will most likely get the same job done. i.e. a clock speed of 902400 is more then enough to run the process quickly ondemand will jump to 1708800 to handle the same task.
copied from the above link at android forums.
" * ondemand - Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see "up threshold" in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed.
* conservative - Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery.
* performance - Available in most kernels. It will keep the CPU running at the "max" set value at all times. This is a bit more efficient than simply setting "max" and "min" to the same value and using ondemand because the system will not waste resources scanning for the CPU load. This governor is recommended for stable benchmarking.
* powersave - Available in some kernels. It will keep the CPU running at the "min" set value at all times.
* userspace- A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor."
Please post in General section, not dev.
Well i changed my setting a little to be a bit more responsive and i haven't noticed a increase in battery usage. I set my max speed to 1516800 and min to 368640 and its running quite nicely.
Anyone else getting good result with the conservative setting?

Is there a way to change voltage? Frequency rules saves are minumum on cellphones.
I'm using Setcpu 2.1.0 and I'm using a stock OC Kernel from Grankin01 and u have to set the profile to conservative.

Frequency rules saves do save a lot of battery. Combine with undervolting and memory optimizations and you'll get big saves. But no setcpu is solely for cpu settings.
Whats the most stable speed to run this at?
So far i haven't had any stability issues on the Grankin01 Kernel. They ironed out most the stability issues in the Kernel its self. I do however keep my main profile around 1708800 - 1516800, generally 1516800, and min is set to 368640 and I've had no problem not even a signal freeze or crash. I've also run at 1708800 for most of the day plugged in and no issues other then heat. So i think is up to mostly prefrence.
I'm using a stock rom with bloatware removed and as i mentioned the Grankin01 1.7 OC Kernel.
Here is what I'm talking about. Sometimes the auto detect or something is wrong and I get this screen instead of the one you get. I don't understand why. I change ROMS a lot and I don't know if it is ROM specific or not. I'm currently on the cm7 preview from Zinx. Although I have seen it on other ROMS also as I posted before. Here is a pic.
Ignore the dropcap2 as I had just used it to take the picture.

Looks like from your screen shot that the profile SetCPU is using is on On demand, interactive or some default. What Kernel are you using? that may be the issue. If not a kernel issue. Then it may be a issue with CM7 and how SetCPU interacts with it. try disabling all your profiles and make sure that your main profile is for sure set to conservative.
Nothing else make a backup and try a different Kernel. Grankin01 has a few great ones and even a CM7 kernel with tunes and tweaks. As well as Gorilla. but id try the CM7 Kernel Grankin01 has first my buddy is running it and hasn't had problems. Just make you do a full backup to avoid a FUBAR situation.

You are right it was the main profile was set to on demand and when set to on demand these available options change.
As far as kerenls go I have not had good luck with Grankin CM Gingerbread kernels but he is working on a fix.
Can you experienced doods, help out a noob? I have recently rooted my phone (after MUCH research and reading) and just installed Set CPU app. I have been reading about the different settings for Set CPU, and it appears to be device specific, so I wanted to know if any can suggest some stable and useful settings and profiles I can use.
My goal would be to extend battery life and increase erformance while the phone is being used. I kinda guess this is most peoples reason for using this app. Slow the CPU down while the screen is off, and increase it a bit when the screen is on. I am not totally sure why you adjust it while it is charging. And wold this fi into the screen is off profile.
Ok enough rambling, and thanks for any assistance!
Forget SETCPU. Voltage Control is the way to go. For battery life, I would underclock to 100-800mhz and have -100mv all through the range. For performance, 100-1400 mhz (1.5 & 1.6 ghz are heavily overvolted) and have -100mv from 100-1000 mhz and -75 for 1100-1400. Leave the governers and io schedulers where they are.

Using the voltage control within SetCPU or a voltage control app?
Thanks
Edit: after installing set CPU my phone seems to be running slower than usual. So, I ran a quadrant benchmark and it is coming up with much lower scores than it did before. Is there any way to set it back to the original cpu speeds with out deleting the app?

Tried those settings and my phone froze a few times so I upped the voltage to get it to work for me. This is my first time overclocking a phone. Do any of these settings look strange using voltage control?
100-400mhz uv-75
800-1000mhz uv-50
1200-1300mhz uv-25
I haven't froze yet, although I noticed my battery drains a little faster then normal (that was expected).

Yeah those are kinda high 'performance' settings, not all phones like being overclocked or undervolted much less both lol.. Start with it just overclocked for a day or two and see how it runs, however there's gonna be some serious battery drain obviously. Then move on to undervolting slowly like maybe -25 across the board and leave 1400 alone for another day or two... just experiment like this until you have the right balance of speed, stability and battery life. As a matter of fact I toned mine down a bit afterwards and it worked nice:
Overclocked to 1.2ghz (1200mhz),
took out 600mhz frequency and set 100 to -75, then 200-800 at -50, 1000 and 1200 at -25
or if you want battery life and don't mind sacrificing a little performance you can underclock to 800mhz and set all to maybe -75... its a lot of testing to find what works for your phone, if it reboots freezes or lags too much its either overclocked too much or undervolted too much
edit: I also use the free voltage control app from the market, it lets you set min. and max. clock speeds as well as voltage so thats all I need lol

Roms are not always all inclusive with a kernel and whatnot.. Most are custom apps, themes, and build/framework remakes to operate on top of the stock roms and will use stock radio and kernel to operate unless a custom radio/kernel is flashed. While most radios and apps will work well with different roms, kernels (being basically the 'engine' for the android OS i believe) are dependant on baseband and will not work by switching them around or flashing one over the other. This is the way I understand it to be anyway, I just know kernels are not compatible between 2.2 and 2.3

Makes sense. I'm sure the apps and radio are dependent on the kernel as it is the core. (like an Operating system that provides the platform for applications to work.)
I'm sure the developers thoroughly test these combinations before releasing any ROM, .
However I want to have some fun updating the kernel on the GC GBE 1.9 that I currently have on my charge with couple other kernels out there....
Will see if I create some magic

To avoid: IO schedulers, overvolting (only done in Extreme), and going above 1400 mhz, as 1500 & 1600 are HEAVILY overvolted. Toasted processors=bad magic.
However, you can switch the governers from conservative to performance, but its kind of useless.
If you delete the app it will NOT go back to default...I think. The default io scheduler for imoseyon's kernel is deadline, I forgot what PBJ's is. If you switched it and its still working, don't worry about it.

I've seen some general advice not to UV for anything over 1ghz speeds as well, but it may not hurt to try if you want and adjust as needed for stability.
I'm running on a -75mv at 1.5Ghz faux kernel 0.4.7..
Perfectly stable, benchmarked AnTuTu, Quadrant, and all those other good stuff.
I have not tried -100mv yet, I doubt it will be stable.
Every phone is different, but I run mine at -20 up to 1 G, and -10 for the rest.
Mine I cant undervolt shoot I have to keep my minimum frequency at 500 to be stable, course I can also run at 1.5 all day (I keep it at 1.2).
Well I guess I can't say I cant UV since I use pimp my cpu and it only gives you options in 25 increments, maybe I would be stable at like -10. But coming from my galaxy s 4g where I could UV over -150 and still be stable, that just doesnt even sound worth doing.
Edit: I just thought about it and maybe the reason I cant UV (more) is because I'm using fauxs pre UV/OC kernel, so I dont even know what stock voltage is. But comparing to my sgs4g at stock voltage I am running considerably lower voltages on the g2x.
The faux thread says it's pre uv at -50 across the board.

Good evening all,
I am currently running vb with the latest above kernel and xda-edition of setcpu...
My question, has anyone found voltages that are stable?
I have always/only used tegrak, when adjusting the voltages I am able to adjust "internal" as well as "core" voltages, as you may know setcpu only allows the adjustment of one voltage. So, I set all levels to the "internal" voltages that worked for me on tegrak(scaling set to smartass), everything was working fine until I rebooted the phone... At that point the phone would boot then freeze after the third media scan, I had to flash back to the b1 kernel to get back up and running.
Any advise would be greatly appreciated.
Thank you in advance!

You're trying to undervolt? Anton's b5 in undervolted. I'd stick with his recommended values.
How do you actually implement these voltages? I've only used Tegrak so this is new
Sent from my SGH-T959V using xda premium
QUIETLYloud , I dont't have paid Tegrak so I cannot make a thorough test.
I tried using very old Ultimate version available someplace on the web, and it does in fact seem to mess the phone up. I didn't need to reflash, but had to uninstall Tegrak, reboot, clear caches, and rescan SD for errors. Google says that there were issues with Tegrak module and custom kernels, but they were supposedly fixed around version 1.4.
I tied the new free version 1.6.7 from Market. It doesn't let me do much (like setting on boot), but at least it seems to work correctly with frequencies.
The setup with OC kernel is a little different. Before, if you wanted to OC, you would go and enable CPU Max Frequency, which would replace 1 GHz. Do not go there! The kernel already has all overclocking frequencies available. Instead set the Scaling to the highest frequency you want to use (let's say 1.2 Ghz, which is CPU Level 2). Then go to Optimization and set desired voltages for the frequencies you chose. No need to change anything for frequencies above you max scaling, the CPU will not go there anyway. Maybe it's a good idea to completely clear Tegrak data and start setting it up form scratch.
Let me know if you succeed.
Btw common Google knowledge doesn't seem to recommend lowering internal voltages. You will not gain much, there is just not a lot of current draw there. It's the core that draws a lot of current.
EDIT: Hmm... Tegrak seems to have a problem with smartassV2 governor. If the scaling in Tegrak is set to use anything but all frequencies, including 1.4 Ghz, the governor will never lower the frequency from the highest selected. The kernel itself (with SetCPU or without) doesn't have this problem, it's only when proprietary Tegrak module is loaded.
AntonX...
I decided to scrap tegrak for the time being and use what you recommended with setcpu and left voltages alone until I have a better understanding, since doing so haven't had any problems
Sent from my SGH-T959V using xda premium
Btw I said before I set the default voltages kind of safe, even if they are slightly undervolted. I'm running the kernel UV-ed a little more with SetCPU for second day without any issues. Here are my numbers right now:

Hi guys
I apologize for some noobness coming this way, but I don't understand. Kernel beta5 is oc/uv - what does it mean if I don't use setcpu/tegrak?
Will kernel behave other than prior versions?
And if I decide to do use setcpu? What good does it make if uv makes no change (according to Antonx) and oc will only drain the battery even more, I mean, phone is pretty much fast, so why bother oc it?
Thanks!

I can't seem to get my Min/Max CPU frequencies to stay locked in regardless of Governor or IO Scheduler I use. I can't figure out why ig s doing this. I've never had a problem before. I am running everything stock right now except cot Root and Custom recovery obviously. But other then that. The phone is stock rom/kernel.
Can someone help me figure this out. It keeps setting my min frequency at over 1Ghz, which I obviously want it to be able to drop down more then that so I can save battery life.
Any ideas?

do you have busybox installed? im sure that your cpu control app needs it. grab the busybox app by stericson, install it, open it, then install busybox. check if your cpu speed sticks. if it still doesnt, could just be mpdecision. then it would have to be disabled.
Yea I have busybox installed. Its always one of the first things I do. This isn't my first time modding a phone lol I've been modding phones since back when the Droid 2 Global first came out. Even started developing my first App and Custom ROM recently.
I use Jrummy's Busybox Pro app tho.

Mpdecision. I've seen that in FKU, I can't remember off the top of my head what that controls. I thought it had to do with thermal settings for the CPU

It is mpdecision. Its supposed to make the launcher smoother.
Some kernels allow "stop mpdecision" from terminal.. or in chaos kernel, dev got mpdecision to pretty much boosting min frequency

I thought I had seen Mpdecision controls in the FKU app, but I musta been thinking of something else cause I can't seem to find it now. I just flashed Franco Kernel r32, and Now it seems to be keeping my Min/Max Freq locked to where I set them. So the issue seems to be fixed on its own.
I have the governor set to interactive and IO set to Row. Still learning about what IO scheduling does so I just keep that to whatever the kernel has it at by default.

Here's a screenshot
Yes faux used to have mpdecision controlsw. I haven't used it or a while though
This isn't really a solution more just avoiding the problem on your current kernel, but if you want to do this I recommend Chaos kernel :http://forum.xda-developers.com/showthread.php?t=2551441 Comes with the NXT app that allows a lot of tweaks to the CPU, GPU, memory, and so on.

Thanks for the link, so far I got it working alright ever since I flash the latest Franco kernel. Got max set to 1958Mhz & Min @ 422Mhz with the voltage dropped by 25 from stock which at 1958Mhz, the voltage is 945mv. So yes everything is staying to where I set it now. If I have any issues again tho I will try the idea in the link.
Thanks to everyone else for the replies as well
