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.

If undervolting is impacting the performance of your phone (in your case, the signal strength) then it can be argued you're undervolting too much, even though your phone is stable otherwise. About the only thing you can do is try undervolting a little less. Every phone is different regarding this kind of stuff, so it's a trial and error situation.
Or I suppose you can try different radio/RIL combinations. But I haven't read of anyone testing radio/RIL performance at different voltage levels so there's no evidence to suggest this will fix your problem - just throwing ideas out there.
I tried the -25 undervolt and my signal is up to an acceptable area would be cool if i could get the -50 but oh well still going to get good battery

Well, I'm no electrical engineer, but common sense kind of makes me agree with Henry...
Radio needs juice/cpu time to operate.
Undervolting reduces the amount of voltage supplied to cpu, perhaps other components.
Reduced power to cpu/radio/etc. = reduced performance.
Especially if it worked fine before undervolting. Really doesn't seem that mysterious to me.
Keep in mind you're doing something to the phone it wasn't originally designed to do. Just because it can tolerate it, doesn't mean it's going to tolerate it AND behave as if everything is normal.
Is it possible just to install the undervolt zip or do have to have the kernel that goes along with it?
Is it possible to change the amount of undervolt simply and easily?

This I am aware of. I mean is there a way to change the amount of undervolt in MDJ Kernels to try to improve signal strength? or are there any comparable non undervolting kernels with all the features still there?

Usually, yes. For example, some of the common kernels being used to undervolt the Inspire are LorDMoD kernels. He's got 4 undervolt scripts that will undervolt your phone to various levels, depending on how low you can go (every phone is different). Some users have created their own custom undervolting scripts as well.
-25mv script: safe for almost all phones
-50mv script: safe for many phones but not all
UUV (Ultimate Undervolt script): you're starting to get into some serious undervolting here. Doesn't work with a lot of phone
PUV ("Pinky" Undervolt script): crazy undervolting (LorD ClockaN calls it "heavenly undervolt"). The PUV script is stable on a fairly low number of phones.
These scripts are contained in separate downloadable .zip files that you simply flash in recovery mode. The .zip contains a script file called "99voltages" that is copied into your /system/etc/init.d folder. Any scripts placed into this folder are automatically executed upon bootup. Once this script runs, it sets the voltages for your CPU at various speed levels. The voltage of your CPU can be verified by viewing the vdd_levels file located in /sys/devices/system/cpu/cpu0/cpufreq. The voltage of the CPU changes as the frequency goes up and down. Typically the higher the frequency the more voltage is needed.
Sorry that was probably more info than you asked for.

So can one simply edit the scipts in the kernel packages to try to improve signal strength?
Also, is there any way to determine the current undervolt on my phone? I am on mdj v23 atm.

I thought someone might ask this, so I edited my post a little bit ago to answer this. Check the bottom of my last post and I mentioned what file to check to see your voltages.
One thing I should mention is you probably shouldn't give too much credence to undervolting. It is not the big battery saver you might think it is. It does help somewhat, but even using the extreme PUV script, the net effect to the battery is about 10% improvement in standby mode, and the more conservative script settings are considerably less. If you want more detail, there is a discussion in the last few pages or so of the LorDModUE thread listed in my sig where we discuss the merits of undervolting. Of course on a phone like the Inspire with a measly 1230 mAH battery, every percent counts and is welcome, which is why I'm a fan of undervolting. As was pointed out in that thread, when your phone is being used with the screen on, the largest battery draining component is the display. When your phone is in standby mode, the largest draining component is the radio. A CPU voltage drop of 25mv is only 2.5% (which equates to ~5% power consumption drop by the CPU; see LorDModUE thread for the formula). Given the fact that the CPU is far from the biggest draining component in the phone, the total net effect with a 25mv drop is much less than a 5% improvement.
To answer your other question, yes you can edit the scripts yourself if you're willing to invest the time and effort. I don't know if it's worth the effort in most situations. For example, King Askaba's signal is fine at -25mv but starts to degrade at -50mv. Finding the sweet spot between such a close set of voltages (-25mv versus -50mv) isn't going to make a difference in your battery life.
Thanks for all the help but if i can't have good signal then I wont undervolt. Especially when it not that much of a battery saver.

I'm with you 100% Not worth the trade off.
I am using inspired ace with the mdj v23 kernel. There was no system/etc/init.d folder wasn't there. So how do I restore my voltage to its full power with this kernel? Also the method to check did not work as that file was not found in root explorer.

My bad, I was referring to LorDMoD kernels which only work on AOSP ROMs, so those folders/files won't apply to your ROM. I'm not familiar your ROM/kernel (I think I got confused on who I was replying to since you and King Askaba were both chiming in, my mistake).

We can't tell you not all phones are the same, uv a little (10 or 25) run it for a day or two see how it acts, if its steady, uv a little more, when it starts acting up thats your limit go back to previous settings.

Sent from my LG-P999 using Tapatalk
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.

I want to share my setup with you guys for getting good battery life which lasts the day without making you compromise on the features. The primary things I've seen on the forums so far has a lot of involved setup and frankly by the time you get it perfect, you will flash a new ROM and have to re-do a lot of it and so on, overall it's not the worth the hassle.
This is usually what my days look like and I manage to last the entire day:
I keep wifi and GPS on always, regardless of whether I'm using it or not.
Get a fair bit of calls because I live away from family so they all call a lot (I have a massive family, so we are talking about 5-6 hrs of talking everyday).
I like to read news from news republic and I'm subscribed to a lot of stuff there so I go through like 2000+ articles in a given day.
XDA like every few hrs (damn ICS!).
Text messages are also flowing throughout the day with the woman being on the other side of the country and all (100+ a day?).
I have facebook on push (not an addict but active enough to mention)
My gmail, school and exchange are all on push for email so they I see a fair bit there
The setup is VERY easy to setup and replicate. It doesn't require you to lose out on features or use your phone at an anorexic level either. You don't need a task manager or watch your processor non-stop either.
So without further delay, here we go:
Pick a ROM
I'm using Seanster_GBaxe EX v1.5.1 from the T-Mobile section, you can find it here.
Get faux's kernel
The reason for this particular one is because it's given the best results when it comes to undervolting and overclocking without SOD. You can find the kernel here.
Get System Tuner
This is available on market. There are alternatives but for this post, I will be making all the references from this app.
Get the AGPS patch from crypted
This isn't for battery directly but it does get locks VERY fast and you waste less clock cycles getting the signal. Less clock cycles wasted, more battery saved. The patch is available here.
I personally use the v3.0 Google CWM Build (scroll down his post and you will see it)
Get the V6 SUPERCHARGER from zeppelinrox
This is available here. Why the beta one? It works fine.
Okay, at this point you can pretty much store these things together in a neat little folder on your SD card because it makes a perfect library. So let's get started, I'll assume that we are starting from scratch. The order for everything will be as follows:
Get into recovery and install your ROM
This I shouldn't have to explain, the instructions you can find on the ROM thread.
Install the kernel
Same with this, read the kernel thread.
Install the GPS patch
Same with this as well
Boot into ROM
Hmm.... hopefully you can manage this
Restore all your backups and apps, accounts and whatever else
Using titanium here is always good
Install System Tuner
Okay, let's get started. Although faux has done an amazing job with the kernel, there's always the personal bias that goes into making things so his balanced settings might not reflect yours (nor mine but you will be tweak even those soon).
Inside System Tuner, go to CPU:
The first you thing you should choose is whether you want to keep the 1.72 GHz OC or not. I kept it but if you want to get even more you can lower to stock 1.56 GHz or go even lower, your choice. Once you set the max, set the min to 384 MHz. Set it once and you don't need to do it again after. Leave the governer to ONDEMAND.
Now go to the Voltage tab:
Be careful here, this can crash you if you go too far. What we do here is globally undervolt, you can do that by hitting the -12.5 mV button over and over. I use -75 mV (press the button 6 times, for those bad at math). Keep in mind that all chips are NOT THE SAME!!! -75 mV might be too much for you or you might even be able to get to -100 mV, find out by doing it.
Now go back to the CPU tab and hit Boot Settings:
Hit Screen-off behavior:
Governor - No changes
Max frequency - 384 MHz (push doesn't lag at all still so don't worry about notifications)
Max frequency/in call - 384 MHz (yes, calls don't require full blast, they work fine even under 500 MHz)
Now go back
Hit Governors behavior:
Sampling rate - Unchanged (faux has it done perfect)
Up-threshold - 75 (what's this? This means that the CPU will scale to higher frequencies when the load is above 75%)
Power-save Bias - 70 (what's this? This means that the CPU will be "biased" towards lower frequencies when load is below 70%)
Setting the Power-save Bias higher than the Up-threshold is obviously stupid so make sure you did it right.
Now go back
At the bottom, there is a whole bunch of tweaks:
Hit Re-apply CPU settings, choose init.d script (you can choose boot too but init.d works 100% of the time)
Hit Boost app loading, choose init.d
Hit Clear cache, choose init.d
Now go back
Find the Startups section and disable whatever you don't want running at boot (this is purely a personal thing).
Install V6 script
His instructions are very good so I'll assume that you have gotten it installed. Once you have it running, choose option 9, the 1000 HP one. Reboot. Run script again, make sure you've got it at 100% supercharged. Done. Reboot just to be sure again.
All done! Now, I know that was lengthy but here's the awesome part. Make a titanium full backup of System Tuner and you NEVER have to do that again for ANY ROM as long as you use the same kernel!! The script is unfortunately the only thing you have to re-apply, probably that has a quick setup too but I'm new to it so I can't give you shortcuts on it.
Hope you have luck with this and it works for you. I promise nothing and if you break your phone please don't come crying to me because you chose to do this yourself. It works for me so I shared it!! Any suggestions are welcome of course.
Note: NO task manager required!! I will modify this for cm7 if needed.
nice job. thanks a lot!

I'm not in LTE area :-(... Would be nice because that's why I got the phone but then I had to move so can't say anything about LTE.
As for smartass, what kernel are you using? Smartass works very similar to the modified ondemand settings that I set up so it wouldn't make a difference as far as I forsee.

I tried this, will post results later. Thanks for the great tutorial
If you could post screen shots of your CPU Spy that would be helpful! How well does your phone do on going into deep sleep? On average from what to what time does yours last you? I'm just skeptical about setting the screen off behavior cause that usually prevents the phone from going to Deep Sleep.

You're right about the deep sleep, don't let it go into deep sleep. It lasts me 12 hours normally. I'll get you screenshots when I get a chance.

Dont you think the phone waste alot more battery though when it doesn't go into deep sleep? I've also found that WiFi tends to create a nasty wake lock. My set up is Sky ICS Speed with Faux Clock 1.296 ghz max -384 mhz min. -37.5 u/v LTE on all day, extremely heavy usage. 12 hour battery life on average.

From what I've noticed with the faux kernel, it goes into deep sleep after some time on it's own, regardless of the screen-off behavior. I haven't opened up the source to check it out for a better explanation but that's something I doubt is worth exploring since the performance doesn't take any hit.
I haven't chosen to underclock to 1.2 but it should do better than the 12 hrs I get now if I did do that. I have a tendency to start GTA 3 and start playing whenever I get bored so that's why I went OC rather than under. For others looking strictly to use the phone with minimal gaming, this would be a good option. LTE isn't available in my area so I can't test with it but the WiFi radio uses just as much battery as the LTE, if not more I have a feeling.
Trying eugene's kernel from today to see if the lionheart governor does better than the current setup. I will know in a couple of days because every ROM flash needs a couple of charge cycles before it accurately shows battery status.

Do you get any SOD? Everything working okay? Is the setup different than what I've got up there? Would like to know and try it out, can update the OP accordingly.
Just finished with eugene's kernel and the results were pretty disappointing. Looks like the second core is always kept on regardless, faux's kernel turns the second core offline until usage demands need it.
If anyone knows how to tweak eugene's to stop that from happening, do share.

Can you clue me location of his latest ROM? Or is it somewhere in the Macnut thread on TMO side of the fence?

Using darkside ROM at the moment with the faux kernel, had the Eugene kernel but I noticed that the second core is kept alive regardless of usage and that wasn't helping so I changed back to faux.

thanks for the awesome write up!
Did it last night, and lasted the day without a sweat! However, my min frequency wont stick? I have it set to stock frequency 1.5, using faux kernal, and my voltages arent as low as yours (im not a crazy user like you.. maybe an hour of talking a day, lots of texts and emails tho), but i cannot get my min frequency of 3xx to stay. Suggestions?
Thanks!
edit- running stockMod v1.0
im sorry, i have a hard time believing you talk for 6 hours and scroll thry 2000 pages of web and get a day of use. I myself could get about 1.5 days on battery strictly by staying home, connected to wifi all day and barely talking on the phone. i would like to see a screenshot of battery usage at the end of your day
I'm a noobey and I really don't understand how to undervolt my phone could some explain how to undervolt a sensation for better battery,etc.I would greatly appreciate it.

Under voting works by reducing the amount of power drawn to the phone at a selected frequency. You can do this with an app like system tuner or setcpu. However I can't give you a set of voltages for it, because usually there's minor differences in the hardware of people's phones, which means some values may work for some and not others. I would advise to try reducing the values slowly, and do some research on other people's values to see what they have been able to reduce to.

Is this undervolting I use CPU set and I keep it at min 192mhz to 918 MHz.I thought this was called underclocking.Am I wring or correct.How do you actually set stuff to mv?I don't see and settings on there for mv.and what are all the different things that I can actually down set the mv on.could someone please explain alittle more.
Sent from my HTC Sensation 4G
What you did is underclocking, which saves battery but also reduces performance. Undervolting needs a kernel that supports it. You can set the mV for every mHz. I usually put it 50-62,5 mV lower than the standard voltage.
@ mesaman2012
Download System tuner (or Buy its Pro Version)
Start System Tuner.
Tap on "Voltage" button (in 2nd last row)
there u can increase or decrease the voltage (by -12.5mv to +12.5mv)
after u got ur desired voltage Tap on save to save it.
Simple....isnt it ?
I set all the setting to the lowest +12.5 volts.I hope that's alright.any input on this would be greatly appreciated. Thanks!!!

I don't know what exact voltage u have set....but whatever u have set, give it a little time to see whether it is stable or not....good luck.

Now download stability test from Market and run Scalling test,leave it for 15-20min,if its stable undervolt one more step the again stabity test for 15-20min.When test crashes rise voltage for one step and thats it

I dont rely much on undervolting for saving battery i mean it just depends on your usage mate or either way get an anker battery

Does the way I have my phone underclocked matter with undervolting at all?I keep my phone at 192mhz to 918 MHz for just normal use.I undervolted everything down as far as it would go then I +12.5 and when I was using it right away my phone shut off.so I then did another +12.5 and now so far its running alright.I'm going to do a scalling stability test next.If I'm doing anything incorrect let me know please I'm just a noobey. Thanks!!!
Sent from my HTC Sensation 4G
The only way the underclocking influences the undervolting is that you have less mHz values to set the mV for, so for example if you underclocked to +/- 1200 you can't set the voltage for 1500.
Who has undervolted there sensation and seen a noticeable gain in battery?would you say you got and extra he or 2 on a full charge?

I'll try to report back in a week or so. I went from running the standard 384-1.51 to 384-1.72, to now running 192-810, testing undervolting as well. Will have to play more for sure.
Previously, I had the screen off, not in call max frequency set to 810, while screen on was stock xe. I noticed quite a bit of time at 810, so something is consuming excessive cpu clocks when the screen is off.
The major bummer I'm coming across is that system tuner cannot undervolt below 800mv. Since the phone is ideally spending most of its time at the lowest fid/vid state (192 or 384 for example), there's a good chance of stability below 800mv. I haven't done too much research yet to see if this is possible with some other means, but this may help a bit in standby. Of course, if I could just keep the damn screen off, I'd probably be in better shape.
How much less battery do AMOLED screens consume? Saw a One S today, and it does look pretty damn sleek.

Thanks. I've been running Faux's kernels ever since I got my Sensation. I wonder if he'd consider adding the feature. How low are you able to go stably below 800mv and at what frequencies? Figure if I'm going to be idling at 192 or 384mhz, I'd like to get that voltage as low as possible.
Thanks for all the great input.should I change to a bricked kernel?If so what version.I'm running v008b4 faux kernel right now should I use a lower version like a v005?

Very true ..
I'm running bricked n under volt mine upto 700mV....but it wasn't stable..
Currently running at 725mv n every thing running smooth.
