Which one of these would offer the best battery life? It seems the ICUP kernal is over clocked to 1.3ghz and there is no deep idle either so I would think it would be more of a battery drain.

Icup actually performs very well on my phone. I got 17h yesterday with heavy usage. Galados runs very well also. I would say try both for 2days each and see what works best for u.

For the past week or so I've been using Glados 2.4 CFS, and tried a variety of the features (deep idle, live OC, lazy governor etc.), each having a different impact on battery life. Yesterday I just flashed eugene's Icup kernel and so far it seems to have perhaps slightly better battery life. However it's hard to say after less than a day of usage.
Keep in mind that the ICUP kernel is actually not overclocked to 1.3 GHz by default (it is actually 1 GHz, with a maximum CPU freq of 1.3). You need another app like SetCPU or NSTools to set it to 1.3 GHz. And also, the ICUP kernel apparently does have deep idle, albeit a slightly different implementation than the one made by Ezekeel (the creator of the Glados kernel).
As Esteway said above though, the best way to know for sure is to try both the kernels out yourself.

What's the max performance can I get with PBJT OC kernel?
I set voltage to vr/performance at 1400 max...no voltage reduction. Strange i got quadrant score of about 2200 first time but now only 1500 a few times after....same Rom, kernel and voltage setting
What's best way to improve battery aside disabling wifi and Bluetooth? I know brightness is another. I do have juice defender installed too. Also disabling 4G.

Underclock to 800 mhz, with -100mv across the range (or more if your phone can handle it)
Also, calibrate the battery.

I loved the 800mhz setting but I didn't notice a battery increase. All I noticed was a slow down in the browser :[ I might have been doing it wrong, was my first time using setCPU/VC.
I know overclocking is all the rage for more performance. I myself would prefer the gains of overclocking (probably wouldn't be 1.7 ghz atm since that is the performance based kernal, but 1.5 ghz might be doable) with a combination of undervolting for longer battery life.
I know when I was considering a viewsonic gtablet, that most of the kernals that overclocked also undervolted at the same time (how much depended on the kernal and how much of an overclock too).
Advantages to overclocking are pretty obvious, more performance. Undervolting makes the processor (this case SOI) run off of less power, thus more battery life (can be significant if undervolted enough) and less heat, which translates into a tablet that potential has a longer life (heat overtime wears away at life of SOI/processors and sometimes other components), plus much lower risk than overclocking. I undervolt all my laptops, I mostly get my laptop with 3 hour battery life to 3 hr 30min or even 3 hr 45 min on a moderate undervolt. A little undervolting could take this tablet from 8-9 hours to possible 11-12 hours of battery life (plus a little overclock included will add some performance too).
Do any of the present kernals out there try this? If not, I would like to make a request for such a kernal.
Undervolting might cause the TP to be unstable and crash.

it would need to be done in small increments just like overclocking. Same methods are used undervolting as you would overclock. Yes they could both cause instability, if you double the clock speed or cut the voltage in half, it takes time to know the limit of the SOI by using small increments.
You will need to your favorite custom kernel and adjust the volts yourself using Govnah.
But then I also was reading on forums on webosbuzz and you can have screen wake issues to with undervolting

Really? If that is true, I wonder how undervolting would cause that.
The webos-internals-testing kernels include initial experiments with undervolting.
Hello I am wondering whats the best kernel for battery life on CM7 would it be faux or stock? And plus can I just install the faux Cm version start at 1.0 ghz to 1.4ghz, so by overclocking it means it will have less battery life? Could I just install that kernel and leave it at 1.0 ghz? And is the faux kernel better than the CM7 stock in terms of battery and what about performance?
New to this stuff!
Thanks people!
What CM7 are you running? It makes a big difference. Also, battery life is different for every person. So to say one kernel is better than another is based on your use. Now I did notice a difference in battery life and performance when I flashed Faux's kernel. But best advice? Wait a couple days on stock, see how it is. Then flash Faux's or the any other kernel(as long as it CM7 based of course), to compare the results. Of course when your comparing make sure your phone usage is the same, or as close as you can get it

Ya. I flashed the DS OC/UV v.0.4.8 first but like faux says the battery readings were crazy, going up and down all time, I didnt know how much battery I had left. And this was after I calibrated my battery of course. Im using the CM OC/UV v.0.4.8 kernel and its great! Great performance and awesome battery life! Right now I got 38% left with moderate to heavy use on 10 1/2hrs. I posted a few screenshots of my battery use using Battery Monitor Widget Pro. I couldnt post the battery use one cause I rebooted my phone a couple times changing my theme. It reads like 2hrs on battery instead of almost 11. Also I posted a Antutu benchmark score as well. Try one see if it works, no two chips are the same, if it doesnt, he's got 4 different kernels. Plus there's the other kernels that I havent tried yet. Hope this helps!
Overclocking will reduce your battery life but increase your phone's performance. Use an app like SetCPU to choose your clockspeeds and voltages. I don't recommend messing around with voltages until you're much more familiar with over/underclocking.
I've used faux's kernels off and on and never been able to get my G2x to be rock solid stable versus the cyanogenmod kernel but it certainly did increase my battery life by a noticeable amount. Right now I'm running the Trinity ELP kernel and undervolted it even further and I've had absolutely zero issues. If you try faux and don't like it, give Trinity a try.
I prefer Trinity ELP or Faux DS versions if I am in battery savings mode depending on the ROM I am using.
I've heard of battery calibration, how do you do it? also Im using faux's kernel with it coming with uv, but perhaps should I go lower than that until I find a voltage that keeps my phone going, if I use lower the voltage will it affect my performance at all? perhaps any suggestions on what i should make the voltage. btw im using cm7 nightly/faux's kernel.
I would use the ds faux kernel and undervolt the bottom numbers (anything below 900) to 750. Test what works and is stable. Also set a screen off profile that makes pit at 300 something.
Fairly heavy use and I got 13 hours today.
And battery calibration is a myth.

If you have corrupt battery stats they can affect battery.
after changing voltage i lose the reading on my battery and it says 999% in setcpu lol.
also how long can i expect to play gta III until battery running out on nightly cm7/trinity with max ghz set to 1 and -150 voltage from max on every mhz other than 432/216 and no wifi and lowest brightness
Which radio are you gents getting good performance with decent battery life? I'm kicking around T989UVMC6 and it seems to be more power hungry but perhaps its just my area. I don't think this is very good battery life as I've barley used my phone today. I'm considering buying the battery for the nexus as it has a little more capacity and I've read it fits but I'm waiting on confirmation.
Anyways..I'm testing slimbean 3.1.0 build 3 with the T989UVMC6. I'm thinking of trying the LV kernel, what governor and I/O scheduler are providing good results for you guys?

As of now. I am using CM10 latest nightly. Using Bluelightning X2. SmartassV2 and SIO. Overclocked to 1728. Minimum is 192. Getting decent 16 hours of battery life.

Is this the one your referring to? http://forum.xda-developers.com/showthread.php?t=2025488&highlight=bluelightning+x2
You running the standard JB one and not the GPU OC one? You seem to be playing with all the roms and kernels to..how would you compare it to LV kernel. Also, what radio are you using? Does it seem like my cell standby time is high in that screen shot? I have only made two phone calls and had the screen on a few times for a few minutes today. The phone was at 100% at the start of the morning and has been very idle so i'm surprised to see it so drained.

On page 5 on that thread is the link for X2. Flash X2 then the GPU OC Zip.. Using UVMC Radio. Haven't flashed LZ in a while so i don't know.
I'm using BlueLightning with Conservative and SIO, minimum frequency is 348 max is 1188. It's not the best combinauon if you prefer performance, I get about 18 or 19 hours of battery life I'm also using the same radio as you BTW .
