Set CPU Questions

I have a friend on an Android phone. Long story short, he needs to start having better battery life.
I know that having custom kernals allows for overclocking, but all he needs is the underclocking.
If I root his phone, set his profiles up without a custom kermal, would that still help his battery when setting up his max and min settings?

Yes, SetCPU should lower battery consumption. Configure your screen off profile to underclock the CPU when the screen is shut off. You will need to have your phone rooted for this.
you should notice a significant gain of battery life. This thread should provide some more information.

Not necessarily. Underclocking can sometimes use more battery when your phone is active. With less power the process takes more time to activate and that means more juice. Search in threads for "underclock", you'll find more infos on the subject.

Hey guys, what I'm asking is does he specifically need a kernal? Or, can he rootv and JUST use Set CPU?

Imo, he would get better uc/oc results with a modified kernel.

to answer you, no he can use just root and setCPU.
custom kernels help alot. but its not required.

Firstly: What phone does your friend have? Make and model, Android OS version, etc.
Secondly: If your friend wants to seriously underclock his phone, tell him to look into low-voltage kernels. He would probably just be better off with a custom ROM and such. If he has a question, tell him to type it into Google and the answer will most likely pop up.
Thirdly: SetCPU will always help with performance/battery consumption, you just have to be rooted for it to work and learn how to set up profiles properly. Once again, Google is your friend.

CPU temperature?

Is anyone working on a way to monitor CPU temperature rather than battery temperature?

I don't know if anyone is working on it. I also don't know if our SoC has the necessary thermal sensor(s) to make this kind of software possible.

I'm afraid no-one is working on it, and any devs I've contacted for that didn't care at all. I was politely sent off.
The Sensation definitely has the CPU temp sensor (there is often a thermal deamon running on it), but still no devs wants to spend the little time required to make it happen.
NOTE: This requires a custom Kernel, currently available are kernels from Faux123, showp1984 or Leedroid, maybe also from MDJ.
None of them are actually working on that. One of them said that we will get CPU temp in the next kernel update, but that was already 3 updates ago!

(FIX) Wake from lockscreen delay on Cm7

I had this problem and after many hours of messing with my phone I figured this out. I downloaded setcpu. Set the gov to on demand. Go to profile and set a profile for screen off. Max frequency to about 692 and Min frequency to 128. Now this may or may not work for you. It worked for me everytime.

Well known problem for sure. I always set minimum CPU to 384 and the problem completely goes away. On a side not your probably going to get grief for posting this here.

Lol good one. But as I STRESSED it worked for me. I have reflashed from rom to rom and I did this everytime I went back to cm7 and it worked FOR ME. not saying it will work everytime for everyone seeing all phones act different.

Why would i get flack? Its not a theme or app or not even a question. Its a way DEVELOPED FOR ME to work around the problem. If it works for others fine.

I think all he was trying to tell you was this is a know fix for wake lock and although you feel its a "Development" thing many others probably will not. I probably would of posted this in General or change the header to say [FIX] BLAH BLAH BLAH....
You may or may not get flack just depending on if people ignore the thread or not but thanks for your input and I am quite sure this may help some people. Not flaming you just trying to help shed some light for you

hey look he downloaded setCPU when CM7 has built in CPU controls!! bravo
:smh:
screen off profile with a max of 700mhz.. why bother?
in all reality you issue is resolved by having both screen animations enabled & auto backlight disabled.

Does it have govenors or profiles. Look if this is the way people are treated when they post no wonder dev's are getting far and few. It people like u that make others not want to visit these forums anymore. Think I will take my comments and phone and go to another forum with less ASSHOLES THAT THINK THERE SO GREAT BUT DONT CONTRIBUTE **** BUT TO TROLL.

Just so u know drdrewdown. I did that and it didn't do ****. Maybe u should of wrote Try this instead of telling me what I should do. And so u know since u obviously don't by your reply cm7 doesn't have profiles. Maybe next time read the Whole post.

Undervolting

Could some give me a quick rundown on undervolting a kernel. I'm using faux's 0.4.2 oc/uv cm7 kernel. From my understanding its already undervolted but I'm confused about whether I should/can adjust those settings for better results or if I should leave them alone.
Info greatly appreciated.
Sent from my LG-P999 using xda premium

Each chip is built differently, so you have to experiment on that yourself. That kernel may already be undervolted but it may not be right for you. I say adjust until you hit instability and then go from there.

Sorry to jump in on this thread as well, but could you give us some info on how you would undervolt a kernel?
I have setcpu installed, is that enough? Is it possible to break my phone?

Yes anytime you make you phone do something it didn't do from the factory there is a chance you could damage your device..its thx to all the great devs and people that test that make it easier and less likely also the more you read and understand what it is you are actually doing to the device helps alot!
If you have a kernel able to be overclocked/undervolted yes just use set CPU to adjust the settings.
All chips are different just cause a specific setting is working for someone else means it will work the same for you!
That being said I use:
Trigger 8/22 rom with faux123'a 0.4.2 kernel.
My settings:
Max-1408mhz
Min-389mhz
And have 1.1 GHz down to 389 mhz undervolted by 50 and no undervolt above 1.1
also have different profiles set for screen off and in call..
Good luck how this helps..

Thank you for such a detailed explanation! I'll be more weary of fooling around with settings. I'll probably set mine similar to yours.

Thanks everyone. I understood that setcpu would be used for the changes I was more wondering what the changes would do. Like undervolting by 50 for instance, what does that give as far as battery life? Im a moderate to heavy user and I only get roughly 8 hours off the charger before it needs to be back on, great signal all day too.
I suppose I'll just have to tinker with it till I get crashes then adjust from there.

How do u get the undervoltage adjustment? i have set cpu and when i try the voltage button on set cpu, i got forced closed. Thanks in advance.

Sounds like a bad install, try uninstalling setcpu then re-installing it or fix permissions in CWM or terminal
su
fix permissions

Used to have that issue too. Try the setcpu available here on the forums, I think that's the one the worked for me.

CM questions.

Well I'll start with what I think I'd think to be easy and i'm just not seeing it. OC daemon for aosp. I've seen it built in, but how to add to already installed ROM? Now another question. Even with pinky undervolt and the radio that I was recommended for the ROM blackice, I'm getting horrible better life
compared to when I had sense 3. Any idea on that? Thanks to any help someone can throw out.
Sent from my Desire HD using XDA App

For the OC Daemon, I would try searching the forums for a thread dedicated to it. If they have an installable .apk for it, you would simply download that and install like any other app. If its a system app, you would have to mount /system with say ES file explorer, copy it to /system/app and then assign the proper permissions.
My questions is if there is a way to confirm that undervolts are being applied. In the blackice thread some people were saying the included tool might not be applying them correctly. Thought id make a few posts here though so I could post in the actual thread lol.

OC/UV Beater will show you what your voltages are currently set to:
http://forum.xda-developers.com/showthread.php?t=1207546

Correct me if I'm wrong, but if you're referring to the OC daemon in ARHD I think that's written for his CPU scheduler. If you're on AOSP I would recommend SetCPU

Well with the OC daemon question, I have seen people build it into cm based roms. So I was just thinking, if they can do it that way, why not in a preinstalled ROM.

Thanks for the suggestion. After I asked I found out systune included in the rom showed the values and they are being applied.
Correct if I'm wrong but setcpu will anything that ocdaemon can do. I would just use that or choose a rom with it cooked in.

Setcpu just follows governors. the OC daemon uses governors but also has set clock and governor for screen off and on, therefore, saving battery life. Also better performance.

Setcou does all that and more. You can get it for free on these forums. It has way more than screen off profile. It has batt. Temp charging. batt Level profilr and more

Setcpu has always made my battery life horrid. The oc daemon has assisted me in achieving 2 days battery life with average to heavy usage.
