Setcpu problem - Epic 4G Android Development

Rooted my phone but have stock rom, got setcpu from the market to try and get more battery life. Not too familiar with how it works but set it on "on demand" and after a few minutes I get the red charging led lit up and no display on the screen. End up having to pull the battery and restart. Anyone familiar with this problem and advice on how to use this app?

Best place for SetCPU support is probably the developers thread here.
I've never used ondemand. I have used conservative and interactive and like them, but it was always on a custom ROM.
Recommend you consider a custom ROM if you're comfortable backing up, wiping, and flashing. I didn't try to overclock or modify the stock ROM/kernel, not when there are kernels that will undervolt and overclock -- options you can't get with stock kernel.
I tried a few of the kernels/roms here for the Epic - but went with Syndicate ROM/Kernel.
Good luck!

On the stock kernel they recommend using only conservative for our phone. Most people were still having problems with the screen not waking up (as did I). I also recommend using a custom ROM before you use set CPU.

Setcpu?

Anyone here try setcpu on your Galaxy S 4G?
I'm sure there is some "new and improved software" reason to not need it, but I figured I would try it to see if I could improve battery life in some way.
I'm still tinkering with the settings, but I think I have noticed a slight improvement. If you try it, don't set your screen-off speed to any lower than 400mhz. If you do your phone will slow to an unimaginable crawl, sometimes only to be recovered from with a reboot/battery pull.

You can use it but until there are custom kernels that allow you to underclock or overclock its gonna be a lost cause imo. At this point its only good for changing governors and possibly screen off profiles and things like that

It already hauls once I removed bloatware, my system is pretty "bare bone" now, and it's FAASSSTTT.
That being said, one of the main reasons I upgraded to this phone from my modded HTC HD2 was the battery life was horrible on that phone (comparible to an evo 4g as per many side by side tests with a friend who had a new one).
Battery on this phone is GARBAGE, basically the SAME battery life, maybe only slightly better if at all....
I thought technology was supposed to be improving. I mean I abuse the phone, It's my sole entertainment while I'm at work (I work at a call center). I'm doing things on it 24/7.
But I figured it would perform better than a non-native android phone, modded to run android, that's two years old.. (htc hd2)
I have been using an app called tegrak overclock. it seems to work great for me.

You can overclock without overclock kernel?

I just use setcpu to disable auto scaling..

TegraK seems to work. It's an "on demand, on the fly" patch that isn't persistent.
I see improvements in benchmarks and reads/writes. So, it seems to work. Every time you reboot though, you have to reset it.

Help with kernels and O/C coredroid 6.6

First question:
I'm using no-frills CPU to Overclock. I have HTC inspire 4g running coredroid 6.6 what would be a good starting point for my
Min. Clock freq? And my max clock freq? And also what do the freq's do? Help please trying to get the most out.
Also if someone would explain what the governers are....
Smartass
Interactive
Conservative
Userspace
Ondemand
Performance
Help please
Second question:
How do I properly flash a kernel. Currently using coredroid 6.6 and wanting to flash the new leedroid kerbel. What is the propper way to do so?

If you download the kernel listed in my sig, then you can flash it via Clockwork Recovery. As far as the governers, I'm not too familiar with them myself, but here is a little info about some of them. I believe Smartass is a little newer or made for specific kernels, so there doesn't seem to be much info on that one.
Pretty much trial and error and see what one works best for you. With LeeDroid's latest kernel, SetCPU lets you go as high as 1800Mhz or so, and I had it set to that as max, with 500Mhz (or whatever setting was closest to it), but just lowered my OC a bit to a little over 1000Mhz to try and get some more battery life out of it.
Okay thank you very much. Nobody got back to me last night. I had leedroid new kernel an i flashed it, and I noticed a HUGE difference in how fast it was.
When downloading new ROMS like some say data+++, aosp, an so on.... What does all that mean? I'm very new to all this but slowly catching on.
Also I don't have set CPU, you have to buy it... I have no frills CPU

Even though I've been rooting since my Captivate in August of last year, I'm still a newbie as well. All I can suggest is: Read, Read, and Read some more. That is how I learned a lot, asking questions only when I had exhausted my search- fu.
A lot of the times the answer you need has been answered by someone in some thread.

Constant need for battery pulls

So these issues are getting more frequent. Today I had to pull the battery twice. One time, the phone froze with the screen on. Just now, the network dropped out and when I went to restart it, it never restarted. Went to a lit black screen with the soft keys lit up.
What is going on here? Could these be caused by rooting?
I am running stock ROM, ADW EX, S-OFF, Alpharev version of CWM. Could setCPU be causing these issues? I think I will freeze it for a few days and see how things go....
Please help!
Matt
It's most likely setcpu, rooting and s-offing the phone wouldn't cause issues like that.

Okay, I froze it using Titanium Backup. Any chance this is something that could be fixed at a later time? I like the idea of being able to overclock and underclock.
I know everyone is loving cyanogen. Is CM7 to have overclocking, similar to setCPU?
Thanks for the quick reply!
Matt
Overclocking is done by the kernel and not the ROM. If you haven't installed a custom kernel yet, than having SetCPU on your phone isn't doing much for you. CM7 has introduced their own built in way to set your CPU clock speed although you will still need a separate custom kernel to get any kind of overclock. Be patient, development only really kicked off recentlybwhen we got S Off.

[Q] New rom install

Hello i have just flashed revolution HD on here
And just wondering if i should let it be what overclock settings would be good as it has daemon config installed any way just wondering where to go from a new flash
Sent from my Transformer TF101 using xda premium
Thread moved to Q&A. Also, I am not sure I understand your question.
Well mostly like what setting should i use too gain both decent battery life and the best preformance, androidrevolutionHD is what i just flashed and the kernal im using is 2.6.36.4-g6aa10ba [email protected] #20111023
Is there a differnt kernal i use or an app to have better control of overclocking maybe what settings are best...
Sent from my Transformer TF101 using xda premium
Get setcpu from the market, max out the slider both way (100 min, 1500 max) and set it on either interactive or ondemand, those are good for battery savings.
You can review what the governors do here;
http://www.everythingabouttablets.net/2012/01/22/android-overclocking-governors-explained/
The TF will take 1500mhz pretty stable, I don't recall ever getting a freeze up or random reboot with my clock settings maxed out.
And see my signature for a good noob guide.

Anyone try to undervolt using EB ICS 4.0.4?

I have no experience with undervolting and was wondering what's recommended and if it causes more issues than its worth.
Sent from my LG-P999 using XDA
Its in auto mode if you are using EB 4.04. You can undervolt to four different levels. Check it out for your own which one does your phone likes. Just don't checkmark.. Set to boot. If anything goes wrong, just pull the battery and the voltage is back to normal.
I would have told you where to look but i ain't using EB right now thou i had used it and uv it before on that rom.
