I have no experience with undervolting and was wondering what's recommended and if it causes more issues than its worth.

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.

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.

I have a question about this kernel, i have it installed on the phone and flashed on it, it said in the post from nemesis2all that there was a Battery hack, i was curious how to use it, i currently have settings at Min=400 max=1300 all settings undervolted 50mV, how good are these settings? and would this be the optimal settings for performance and battery life? or anyone have a better setup that would help. seem to be getting high 1700 quadrant scores with how it is now.
In order to get the best battery life you would not want your phone over clocked, I run otb kernel as well and just uv the stock setting starting at 50 for the 1000, and progressively stepping down to negative 100. Anyways I run, 1000 -50, 800 and 600 -75, 400 200 & 100 at -100 and I have great battery life even with heavy usage and playing memory intensive games, paradise island, drag racing, pocket soccer. Unless your phone is laggy after you enable lagfix I think overclocking is probably just killing your battery faster the only roms I used light oc' ing for was phoenix and miuiwiz, where both launchers seemed to get some lag after a long days use

The other school of thought on battery life is, if you overclock the processor, it will finish the task faster and return to a lower power idle state sooner.
well also i used SuperOneClick to root the phone, is rageagainstthecage a good root to use? or are there better ones out there? also sometimes this kernel like to freeze at start up and i have to re flash it. im pretty sure this isnt supposed to happen. any help or advise is greatly appreciated
I've had issues with OTB kernals before. Your problem could be the kernel, but I see you oc'd it to 1300. That too could be causing it. Each phone reacts differently to kernels and oc/uv.

Are we able to still use any touchwiz kernal from ec10 on the new heintz 57 ee19 updated rom?
Well I re-flashed it and used same ovetclock just lower volts and am pulling a average 2100 quadrant score. Don't know if it means much but no lock ups anymore

This could just be my stupidity, but if you can flash kernels then you have a custom recovery, right? What's the point of using super one click? Wouldn't having the recovery and the ability to change kernels, etc mean your already rooted? Just seems redundant, I never used a rooting app and still use all the root only apps....

Kinda. The only way to flash a kernel is with a custom recovery but you don't necessarily have to be rooted to do that. EE19 is not rooted so that's why you need SOC if you want to root. Rooting opens up a lot of options for apps and moving and copying system files but isn't required for Roms/Kernels.
Anyone have any other general good ideas or cool tricks to do to this phone?

Currently, im doing a bit of testing with the new phoenix 1.1 rom.
This baby can handle some crazy undervolting.
Currently:
1000 : -100
800 : - 100
600: -100
400: -100
200: -150
Going to see what i can get this down to...a bit more tweaking i bet the battery life can get phenomenal.
Try opening and closing the camera a few times in a row and see if it freezes. Or try a quad test, those are usually the things that will cause issues with too much under volting.

Already ahead of you. Up to:
1000 : -100
800 : - 100
600: -100
400: -150
200: -175
Usually ill run 4 quadrant tests and if it passes that it should be stable. Currently ran a 2187 is that a good score for 1.4ghz?

also when using the OTB kernal what are safe settings to use? ive been running it at 1400Mhz but it lockes up and geeps giving me force close things on start up and never stops and i have to reflash to stock and start over? im assuming this isnt typical, can any one help out?
Actually that's probably pretty typical for an OC that high. I know I can't run it that high without lockups. From what I see in the original thread, most people don't run above 1300 most of the time.
Just curious what everyone is getting for battery life on the gb Rom? seems like i have been getting about 11hours at the most and 9 hours normally on barely any talk time with the phone and little texting almost nothing cause im at work for 9 hours. Basically.from 6am to 5pm is all i can squeeze. Btw running the screen at the lowest brightness and even clocked the cpu at 800 mhz

Oh damn, I just keep seeing bad things about the new GB ROM (bricks and everything). :T I haven't flashed it myself yet, but with that minimal kind of use, I could've gotten over 24 hours on Bionix.
Not a pro here, but maybe you can try calibrating your battery?

Try to calibrate your battery. Stay away from flashing GB right now. It will screw your bootloader up for future reference. The bootloader in it is bunk.
I flashed it with open it works great i did notice it changes stock voltage on the cpu to 1325 which most likely caused the drain issue. I can get into recovery though.
Sent from my SGH-T959V using XDA App
I already flashed thru heimdall before the warning came out about bootloaders. So far it's running pretty good. I need an oc/uv kernel though cuz I noticed battery runs warm at times.
Sent from my SGH-T959V using XDA Premium App
Its running warm from the voltages used on the cpu in the kernel dl tagrak pay for it and changed the value of 1325 on the core voltage to 1275 stock or 1250 which i run at currently

Do any of you guys use it on your infused? I have it and would like to use it but I've read a few things were setcpu doesn't doing anything with a custom rom. Id like to get all I can out of my battery.

Most of us who are using infusion (available in the dev section) are using voltage control, pretty much the same thing in a different app but it seems to play nicer with said kernel
Sent from my SAMSUNG-SGH-I997 using XDA Premium App
I'm using SetCPU with the Infusion kernel as it's the first app I paid for, and I feel weird about switching apps right after I paid for one.
Man it's so confusing to have the Infused ROM and Infusion kernel.
What's the difference between infused and infusion? I'm going to a redsox game next week via bus trip and really need to maximize battery.

For using Voltage Control u need to update the kernel. The default supplied one does not allow to use the Voltage Control app available in market (tried just now to make sure).

Infused is a ROM and Infusion is a kernel. Both can be found in the Infuse 4G development page. I've noticed a battery increase with Infused, just make sure you do it a day or two before you leave to get the most out of your battery. Details are in the forum.

Infused is an alternative ROM which eliminates a lot of AT&T bloat. Some of the things it eliminates are notorious battery hogs. It contains a kernel with mild improvements from stock.
Infusion is an alternate kernel that introduces extra improvements from the Community Voodoo kernel included with Infused, including undervolting and overclocking. Undervolting can improve your battery life at the risk of stability impacts if you UV too much, OC will sacrifice battery for the sake of performance.
You can install the Infusion kernel over the Infused ROM.
Note: If you are in an area with weak cell signal, your battery life is going to be crud no matter what you do unless you go into airplane mode.

Thanks for the great reply. I'm at work over 9hrs per day and when I'm in the actual building my phone bounces between 1 bar edge, 1 bar 3g and no service. If I keep the phone still on my desk it'll be all set but once I start walking around here comes no service.
Is the kernal werth installing? I know its a junk question. And can someone link or pm me the instructions. Thanks.

Are you rooted and have 3e recovery? If not, just jump over to the development section and read the root instructions and 3e instructions.
There is a great guide in the thread for the Infused ROM on how to go from rooted+3e -> custom rom, in the original post.
Hey guys...just a reminder....setcpu is free for xda members

by all means support the dev....but for those who did not know.
I use it....mainly for overclocking though. Have not really messed with undervolting yet

Yes I'm rooted and I've been running infused rom for a few weeks now. I just really need to maximize my battery. My phone has been off the charger from a full charge for less than an hour and I'm down to 87%, btw I've used my phone for about 15 of the total 60 minutes it's been off the charger.

Really, time to empty is what you need to pay attention to. Our fuel gauge seems to be a bit wacky, sometimes it can drop 10% in an hour, then it'll drop 10% over the following 4 under the same workload. I think the drain isn't actually changing, just the display of state of charge.
As an example, at one point yesterday I dropped 10% in an hour with the screen off for nearly all of it. Then I threw it on the charger and regained 9% in 20 minutes - even with my tweaked charge current it NEVER does that. I think what happened is that the original 10% drop was bogus, I got it back so fast because it was never really gone to begin with.
Ive recently been getting SoDs occasionally while the phone is in my pocket or sitting on a table. The phone refuses to wake requiring a battery pull. Im on the latest faux kernel and eaglesblood GB.
I want to find out what is causing the SoDs but I have no way to diagnose it. There usually is nothing out of the normal running in the background and battery stats are wiped with the reset. Is there any way I can tell what is causing this?
Are you undervolting? If so increase your minimum cpu usage if not I would just try another kernel. Trinity kernel has no SoD

Not undervolting and I've been running at 500mhz minimum for months already. Might have to try trinity then even though fauxs kernel gives such good performance
