What's the best Gingerbread Based Kernel in regards to battery life? (undervolt)
I'm currently using entropy's 9-26-2011 kernel. Should i use a previous one or infusion? or other?

Previous kernels shouldn't be any better with battery.
Infusion will allow you to overclock to 1.6, but otherwise should be about the same, unless bedwa hasn't integrated netarchy's cpuidle fix.
LB's hellraiser kernel has the cpuidle fix and to be honest - undervolt will reduce your CPU core usage by only 5-10% in most cases unless you have a device that undervolts like a champ. It won't help radio usage or screen usage.

Love bedwa's work!! But then you have to look at either using SetCPU or Voltage Control? Which one are you using? Or are you using Both?
Voltage control free works very well with the Infusion kernel, but so does setcpu, seems to be up to personal preference but I would avoid using both as overlapping could cause issues... Voltage control and Infusion 1.1 are my personal prefs because it allows you to change the I/O scheduler as well as UV and OC. Setcpu however can control thresholding. Which one is more important to you?

What do you think is the best OC/UV app ? If so can you also post the recommendations ? THANK YOU IN ADVANCE!
There's been thousands of posts, not sure of threads, in the forum regarding this.
Tegrak OC seems to be the most popular though. Most tend to stay away from SetCPU.
I personally never OC or UV. I find that my speed and battery life are perfectly acceptable.
Yeah tegrak seems to be what everyone uses. I stay away from OCing though because i don't really see the purpose of OCing just for browsing the web, text messaging, Facebook, twitter, and YouTube. The phones really smooth already. I'm probably going to UV though to get a little better battery life.

You can't oc with set CPU without an overclock kernel

Tegrak Ultimate since it allows OC/UV with a kernel module as opposed to requiring a OC/UV kernel.

For this phone tegrak is the best with the most control paid version is well worth it
at first this phone relied on overclocking but months later it is no longer needed imo, i just stay at 1000 mhz stock with undervolting and my phone feels as smooth as a 1.2 thank you gingerbread lol

I use tegraq (paid) version to UC.. everything is so smooth now, the UC gives battery life and my quadscore is still in the 2500 range.

Hi,
I'm interested only in UV, since my phone is super fast with Valhalla 1.1 ROM
and Adrenaline Shot X, but i drain my battery every day!
can you please explain -
1. can i undervolt using the free edition of tegrak ?
2. do i need to replace the kernel or can i work with tegrak app out of the box?
i didn't get that.
Thanks !
Well I just downloaded Taegrak ultimate, but it seems like my values will never stay ! I tried setting my CPU Lv 0 to 1000,1165,1055 but it'll always revert back to normal. Sometimes I'll catch a glimpse of "Targrak has unexpectedly.."
I'm sorry for the noob question but I really don't understand voltage terms and what's it for and how it work I was wandering if anyone could explain it to me?
In the past I would use set CPU and create a few profiles and would be done with it but I been reading on the forums about setting voltages higher and lower for better performance.
Currently i'm on eagles blood 2.3.5 ROM, trinity t15 (fun) kernel.
Any help would be much appreciated.

It's to save power and get better battery life. You lower the amount of power the chip gets at various clockspeeds until it starts not working correctly, then back up to a voltage at which the chip is stable at that clockspeed. Some chips can handle lower voltages than others while still working correctly.
Overclocking = get better performance
Undervolting = get better battery life
Both can lead to phone instability if you set the values to extremes.
Thank you for the info

It all depends on the kernel your using and if it supports UV, it should say if it does in the name of the kernel tho(just look for uv ) Setcpu 2.2.4 will allow you to change voltages only if your kernel/rom support it.
you can safely undervolt -50 -75 at most all the way up to 1.0ghz-1.1ghz i wouldn't undervolt past that.

So what your saying is I can use setcpu to change the voltage?I just recently changed kernels I saw that option available but I didn't understand how to use it.under voltages it shows all the GHz underneath it it shows 0.From here what do I do?, do I go too each GHz profile and -50 from all of it?

I'm having a problem with my phone heating up randomly. I would like to try a kernel that has no overclocking or undervoltage to it, but has the Voodoo patches and the wake screen. Does anyone know of a kernel that would be like this? The ones I found with both of these are ether overclocked and/or undervolted.
you can easily adjust voltages and clock speeds of any kernel to stock values by using setcpu or nstools
Any kernel that supports "Live OC" usually comes with stock frequency and voltage level so you can use it as-is. Only have to enable the "Touch wake" feature -- I recommend using NSTools for this.
GLaDOS and franco.kernel all offer stock speeds and no undervolt if you don't touch anything but integrate Ezekeel mods. If you want however you can overclock with them.
I would recommend Matr1x but it has UV haha

Anyone here use SetCPU with their device? Notice a big difference?
Care to share your configurations as well?
What kernel are you using?? if you use faux123's kernel than he has fuax clock specially made for his kernel.

if using the Original Romracer kernel....there is no over clocking or undervolting. so the only thing you can really change is the scaling.
so if you want speed, set it to preformance which will force both cpus on line AT ALL TIMES. but will drain the batter faster other than that. there is not much you can do with a stock kernel. which is what romracers kernel is.

Hi,
I'm on TPC V3 with Da_G 0.43 Kernel.
I've one profile in SetCpu which is "screen off: max 192 min 192 with smartassv2 governor". I'm a light user and my record is fifty hours with a battery life.
I can't say if SetCPU has a lot to do with this but the smartassv2 governor helped a lot for sure.
I am rooted with the stock ROM and find that setcpu makes my phone lag more with Faux Kernel. When I delete the app, everything runs much more smoothly.

Try using FauxClock with his kernel, it's an app designed for his kernel specifically, and works great.
I'm at 1.2GHz (battery life) with a 87.5mV underclock on all steps, runs like a bauss.
I will admit, Da_G's kernel is miles ahead when it comes to performance, but it SoD's way too much on my phone, unfortunately.

I have to give it a week or so to see how battery consumption is.
You guys' phones are so heavily undervolted.
No performance problems with that? Music playback difficulties?

No problems for me. And performance governor means the phone stays at max frequency all the time. You should never use it for real usage just for testing.

Undervolting has zero to do with performance. The danger with undervolting is instability. If you undervolt too much, you'll crash because your CPU can't draw enough power to do an operation.
A certain CPU is able to do a certain amount of work in a given clock cycle, and that amount of work does not change in the slightest with voltage.
EDIT: Also, as JihadSquad said, performance keeps your CPU at 100% maximum clock speed at all times. It doesn't let it slow down. It is brutal on a battery for no real world gain.
Anyone notice when using smart ass governor it won't overclock to 1400 , it can over chick anything else but not 1400 for some reason so I have it at 1440

Or unlucky. At SetCPU's default for 1500MHz, it's running +325mV (+27.7%) from stock. So it's either really good silicon or a contender for a replacement in a few months.

For one thing, you're running an EP4 kernel with a FP1 rom and radio. Install a FP1 kernel, either stock (http://forum.xda-developers.com/showthread.php?t=1582470) or PBJ (http://rootzwiki.com/topic/137-05-04-12peanutbutta-jelly-time/) and go from there.

I think I need to deal with the file system first. I have that discussion going in another thread.
Perhaps Odin back to stock and reapplying changes in order is in order.
