Hey all just curious. On some kernels I see it allows me to adjust the values and save them upon reboot. Im trying different sampling rates and might have a decent set up if anyone wanted to try it to save battery. I came across a nice write up somewhere ill link up later when im on a computer that inspired my testing.

ya its overclocking its nice makes the phone fast
Maybe I dont understand im talking about the advanced tab. It allows to manipulate the scheduling of the cpu. As I understand it the lower the sampling rate the more often in a second the cpu runs its tasks. So by raising that number the cpu isnt constantly running the same tasks as uselessly. This is my rough understanding and my juice plotter results are substantiating my claims.

Undervolting and profiles.
I have tried a crap ton of different undervolting setting, but none work
Also the profiles in set cpu don't seem to work for me. I have a few of them set and it always sits on the top one I need some guidence with both please!
Another thing my xda premium app isn't pushing my notafications yes its set

Undervolting is a delicate process. It takes time to find the max undervolt that is stable. With that being said, try undervolting everything by the lowest amount which is -25mv. Check to see if that is stable. If so proceed to go further. Remember lower freq will typically undervolt farther than higher frequencies.
As far as profiles go your probably not using the priority values right. The higher priority is what determines which profile setcpu uses. So for instance if you want a safeguard against overheating, you could set the profile for when the cpu goes above 55C to throttle the processor way down. If you set this profile to 100(max) it will overide all other profiles at 98, 99, 75, 50...etc. Also this may be obvious to some but be sure to tick(enable) the profiles button. If thats not ticked then it doesnt matter how many profiles you have set up. It simply wont use them.

When I was on alien rom, I tried 25 on all and it restarted after like a minute. What worked for me was 25 25,50,50,75,75,100 fromm bottom to top. I tried it with cm7 and total no go lol
Lemme tryi 25 on all and see what I get and I didn't know that. They all werent working, so I set them all to 100 lmao, I understand that now

Aparently its been running 125,125,50,75,75,75,75bottom to top cm7 with 1.3 kernel.
It did restart a couple min ago randomly. Will keep posted

Glad your getting some results. If it restarts even once it means at least one of your undervolted freq isn't stable. With your settings I would wager its in the uper freq considering your undervolt in the lower freq isn't too extreme. You might try decreasing the undervolt for your upper freq to -50 -50 -50 starting at the top. Might help to stabilize bc higher freq just require more voltage. If that proves to be stable continue trying to reduce the lower freq as much as possible. Mainly bc if you set your profiles right(screen off is the most important really) your phone will spend the majority of its time on the 200mhz freq. Thus the more undervolt on that freq should theoretically give the most benefit from undervolting. This is just all from personal experience. I'm no guru. Just spent way too much time adjusting voltages on phones . And of course having the upper freq undervolted as much as possible cant hurt either.

Still getting a reboot:'(
Only good thing about the reboot is it turns on instantly
PROFILES CONFIRMED WORKING trying to indwrvolt this thing
I think I'm gonna order another battery too bc this one isn't getting the 16 hours it was, I cant say much bc I'm screwing with the settings hardcore xD I will show.all settings in a sec

Undervolting COMPLETE=D
QUAD SCORE! OCED 1.3 CM7
Right now I'm thinking my battery life is going to be amazig and if I turned the data off when not using it... omg I would last like 2 straight days prolly=D
So pumped to test everything morrow!!
Side note:800mhz or above wont go past 75 >:/
Had really important question to ask you but forgot
Also tried putting 215 to 275 that was a no go lol. My question was is there a battery manager and info like the stock one for cm7?!!!

First off, regarding SetCpu and over / undercloking, dev has said it'll only underclock/overclock ONE core at a time. It's a bug and he's working on it from what I understand. If both cores are needed to be in use at the same time, no over / underclocking will be applied. Secondly, profiles work as they should in SetCpu, so that's a problem on your end. Third, the undervolting can't be more than 100mv differnce between jumps. See screen shot.

I understand the 100 thing and I got the undervolting and profiles done. I hope he gets both cores supported soon and thank you dmfor the reply
Sent from my MB860 using xda premium
Yea Im skeptical about not setcpu not having support for dual cores... Did some searching on the net and couldnt find anything to support that. As far as not the tegra 2 not being able to do over 100mv jumps. That's not true. My lowest frequency is 600mv (-150) and my next frequency is at 750mv. That's a 150mv difference right there... And I'm completely stable. Its entirely dependent on your processor. They are all different and respond differently to undervolting. You just have to find what works for you. Generally though the lesser the jumps in voltage will give you more stability.
a good kernal helps too im useing faux123 v2.0 0C1.3 its undervolts quite well

Ever since I got my hands on MIUI and the Glitch ML kernel, I've been amazed at the undervolt results I've been able to achieve.
I assume I'm not the only one messing around with their voltage settings, nor am I the only one doing so on the Glitch kernel.
Question is, how low can you go? My settings are in my signature, but how far have the rest of you Glitch folk been able to go using the ML or LL kernels? Post your results below!
For myself, I'm currently testing out the low end of the spectrum, seeing how low I can get the 100mhz and 200mhz range and still be stable. Even using 200/100 as my Screen Off profile. I never get sleep of death with Glitch ML.
Either no one reads the General forums, or few people care much for battery savings. Oh well.
It's not that, the lower the volts, the slower the phone. I'm undervolt; games lag

Why would undervolting lag the phone? I'm undervolting, not underclocking. Games I play are as snappy as they've ever been.
It depends on phone i cant go under 25 my other vibrant could go -200 on 100mhz

I discovered something that drastically improved my battery performance even with it sync on all day. If your rooted get the CPU master pro app, and under profiles enable the screen off profile and set the max cpu freq to 918, or lower if you want your battery to be better, i found that 918 keeps me charged all day though, it will depend on how much you use your phone cause you'll only be saving battery when its not in use, if you use your phone alot then just go to the main profile and set it to around 1200mhz
Edit: I'm using RezRom1.6
Thanks for trying to help others but this belongs in the general thread or apps one.

and im pretty sure just about anyone who has been here more than a few months already know this
Thanks for the tip. But I have to agree with everyone above me.
Also..
The title of the post made me think you were making your battery longer... I was like "why on earth would you try to do that???"
I've been playing around with System Tuner since it came installed on Flappajaxx stock rom. Just noticed that in the CPU section, it shows CPU0 and CPU1. CPU1 is showing as offline though. Does that mean one of the cores isn't being used?
Yes. It comes online when needed.
Sent from my SAMSUNG-SGH-I717 using xda app-developers app
Agreed...and "do not" force both cores online...
As mentioned above, the Second core will come online as needed under high load conditions.
If you force both cores online, your battery will evaporate, and your CPU temps will increase by nearly 30%...
I went down this road a week or so ago, and it didnt end well...LOL
Gotcha...good to know.
It does come on as need but it also depends on the users phone and what's running on the phone. I've had both cpus running non stop through system tuner and had no problem with heat and little drain. Again its the user and their phone so best bet is to leave the other one off until needed.

The title pretty much explains it all. I apologize if this thread is a repeat.

Not quite a repeat, but we do have a few threads on CPU governing. Not many people do it though.
If I MUST use an app, I use the smallest one that works. Otherwise, everything gets done with a script.

I've been using no-frills CPU Control, but honestly, there really isn't much of a point adjusting the settings on stock rezound unless you want to save power by using conservative governor and/or a lower max speed setting. It does have a nice feature to show poll the CPU frequency, though: in settings, check "Refresh current frequency" then hit the bar graph on the actionbar at top.
Stock rezound already uses ondemand governor, which is essentially the best you will get out of a stock kernel, and the frequency range is set to 384-1.5ghz by default. IO scheduler is deadline, which does not need messing with either.
Note: Do not set minimum frequency to 192mhz; it uses the same power as 384mhz at any given point in time. Also heard it can cause sleep issues.
I'm using android tuner pretty simple and let me do other stuff. Luczative gov with -50 voltage (testing so far good I'm gonna drop another -25 later)
Bump
I'm bumping the thread because it predates kernel source release and the proliferation of kernels for the Rezound.
I'd love suggestions for a kernel/CPU control app that does the following (I've tried SetCPU, Antutu, Incredicontrol, Kernel Tuner, Android Tuner, etc. and they all seem to do some but not all of the preceding):
1. Let me choose governor and IO scheduler.
2. Let me set range for CPU speed
3. Let me set profiles for (1) low battery and (2) overheat
4. Let me see and manipulate CPU voltages where the kernel permits it; and
5. Let me turn on USB fast charge where the kernel permits it (without requiring a separate app/widget), and of course
6. Won't generate more problems than it solves.
Maybe one of these already does it, but Kernel Tuner and Android Tuner completely overwhelm me with information, choices and settings that are meaningless to me. (And, no, admittedly I do not choose to spend a lot of time educating myself on the subject....I'm a professional, not a computer professional, and I really can't afford to concede the billable time. I have always taken the position these machines were tools that we use, not tools that abuse us.)
Thanks in advance for informed and thoughtful opinions.

I think CPU master is a good recommendation, chad's Incredicontrol would also be nice and it does have the fast charge function.
Antutu CPU Master, which I have been running, does not have the ability to turn on fast charge. Incredcontrol does not permit profiles.

Well it's like you said, you're probably not going to get all of your wish list. Android tuner is a new app that kinda does everything, but it also costs 10 bucks.
Neo uses kernel tuner, if that helps. Just ignore the technical stuff.
