I am running Cognition 4.4.8, which will not allow OC/UC. I actually just want to UC. What recommendation would you have for a kernel compatible with Cognition 4.4.8 for Captivate that would allow me to UC?
Don't you mean oc/uv? I don't think you know what you are talking about.
Yeah its UV (undervolt). Find any kernel that allows it and is working with your ROM. Maybe ask in that thread as others could be using a custom kernel for that exact reason.

UC is a real term, maybe he meant he wants to limit his clock speed to 800mhz. What's that called if not UC?
Although undervolting and underclocking to save battery is a waste of time. The cpu doesn't use that much battery in the first place, the screen and the modem use the most power, you want the charge to last switch to the lowest brighteness and 2g, that will give way more battery than uc/uv will.

+1 on the battery topic. Even at a high OC the battery drain is not that much worse... a little yeah but not too severe.
Also good point about UC.. wasn't thinking about that at all ..underclock what!?!?
some people falsely think that the phone runs at 1ghz all the time, when in fact it downclocks itself and ramps up clockspeed when it needs it....so unless you have an app thats using 100% CPU all the time, your phone is running around 200mhz at idle.

+1 again Although there are different governors that do different things most phone at stock will idle down to 200mhz. My phone for instance idles down to 800mhz, but thats just my prefrence
Yep, I meant OC/UV. I typed too fast for my own good!
Good points
Thanks for the message on how little battery undervolting saves. That was quite helpful. I did try the discussion board for Cognition, but no one seemed to be posting on using an alternate kernel, which is why I asked for recommendations here.
I believe Cog is KB1 based, so this kernel should work: http://forum.xda-developers.com/showthread.php?t=988805
Thanks I will certainly trie eXist's kernel.

If you want the best battery life, I suggest something other than cognition. In my experience, i9000 based custom roms get better battery life.

Yes, I FINALLY did it!!! I overclocked my G2X. I would appreciate if anyone could share their experiences with o.c. pros and cons... Should I retreat or stay where I am? Please some feed back!
Over 1300 seems to cause trouble on mine.
i dont think oc'ing is really that necessary with a phone this fast but if u must i wouldn't go above 1.3 (just seems unstable above that). I think the "Pros" come from being able to underclock. Setting up profiles for uc'ing when screen is off or as battery level drops etc really prolongs the life of the battery (at least in my case)
On my OG droid that came limited at 550 mhz, ya, oc'ing was def necessary but I cant really think of any "Pros" for oc'ing this phone.
each phone is different though so play around and you'll find a combination that works great for your phone, good luck

What about the CPU not having enough cooling and frying the CPU over time. I presume its just like Desktop overclocking but without all the extra cooling you can add to make it safe for the hardware.

But what i really want to know is if oc could damage the phone. After all if there is that danger it's noy worth it...
In all honesty I used to be really into benchmark scores and OCing the heck out of my phone and under volting it in the process but that led to many battery pulls ect. What I've noticed is just keep it at stock and mild uving seems to be the best for me its stable decently fast just 2 cents though
Overclocking a cpu is the same as on a pc, only a bit more dangerous on a phone. (This phone already has overheating problems running at stock speeds ) On a computer, people pay a premium for parts that are easily overclocked, and have either very good fans/heatsinks or a liquid cooling rig.
Overclocking is dangerous, especially because not all chips are going to be made equal, even if they come off the same production line. These chips are designed to run at a certain voltage, and certain clock speed. As far as real world use, (NOT benchmarks. Sure, they look pretty and all, but benchmarks are never very accurate.)
Sure, you might get 2-3 more fps on your games, but is that worth the risk of shortening the life of your chip/phone?
(And just so you know, I've been building/overclocking pc's for years, but I also understand what you need to do to keep it stable, and it's *all about cooling*.)
If you're not convinced, try this. Don't overclock your phone, and use it for a few days. Tell me honestly that you really notice a real-usable difference with the chip overclocked or not. (Games set aside, but like I said, getting a couple extra fps on a game to me isn't worth the risk without a proper cooling setup)
For those of you that really don't understand what you're doing to your chips when you overclock, I'd suggest doing some reading about it. A good place to start would be here: http://en.wikipedia.org/wiki/Overclocking
So you think using fauxs kernel is not safe or reduces the life of the chip? I just flashed it and didnt oc or uv further then fauxs default settings...
Sent from my LG-P999 using XDA App
I'm not saying it's for sure, I'm saying there's a chance.
Plus keep in mind that these kernels have other really nice additions besides overclocking and undervolting. I'm using faux's stock voltage kernel ext4, and leaving it at stock settings, and it really works great.
I just posted this up because I see a lot of people more interested in quadrant scores (which to me are pretty useless) than stability of their phones. If you do overclock, and it works for you, more power to you. I just want to inform people. I'd HIGHLY suggest if you aren't sure, read that wiki article, it's a great place to start. (not all information is there, but it gives a very good general idea on how and what overclocking is.)
Thanks! i always like reading knowledgeable and informative posts!

OK, you definitely convinced me.... I have also faux (let me tell you exactly - Kernel Version 2.6.32.9 FR Faux 123-v0.03) on EagleBlood 1.05. Could you please tell me what I need to do set up in order to be safe? Thanks!
I'd just go to faux's thread in the development section (his froyo thread, not the cm7 one, since you're using eagleblood), and download his stock voltage kernel. (It's in the first post.) He's on .04 now, by the way.
Then reboot into recovery, and flash the file you downloaded. It'll overwrite your current kernel and modules with the new one, then reboot.

And a lot of times the kernel will be credited to the developer. So if you see "faux's kernel" people are referring to kernels by faux123. Trinity kernels were developed by morfic. If you are having a hard time finding a specific one, look at the top left to see who started the thread and sometimes that will help find it. Does that make sense?

If anything it would increase battery drain due to all the processing being put on one single core, what I would recommend for a decrease in battery drain is different kernels with under volting options. That's what's worked best for me.

It was my perception that the older single core phones had better battery life. Do you really think it would hurt the battery?
Dual core isn't properly utilized yet so it might not be a bad idea.

What are your settings?
Most of the time when both cores are on the 2nd isn't doing anything, because the first core isn't even pushed enough to reach max. So, I feel 1 core is sufficient, I'm running 4.1.x w/ 1 core @800 and the battery and speed are fine. Although I see others running speeds of 1.2 and higher, but I barely notice the difference of the freqs. The S3 is so fast that the higher clocks are overkill IMO.

I do see a difference in battery life, which is why I prefer this setup, when we have ICS I will use both cores. But I feel cheated on Ginger so I use 1 for now, and whoever said two cores has better batt is wrong...Logically two cores use twice the voltage, that means 1 cores will save a significant amount of power. A weak dual core w/ 1 core on will have bad life, but a fast on is different.

Every boot, you can make a linux script(.sh) if you want, and then use script manager. But, I'm only testing this for comparison, I can't see the speed difference w/ 1 or 2 so I just use 1. 1 @800 core feels how fast my MT4G did when OC'd @1.4Ghz.

I run Faux kernel, Joe's RCU, undervolted -50mV and underclocked to 1Ghz, I can now easily make it through the day and I'm a moderate to heavy user.

Completely false. Just because something has voltage across it doesnt mean that it is doing anything. Voltage times current equal power. Using power uses the battery.
You guys need to SERIOUSLY change the way you make decisions. Just because something SEEMS logical to you, doesnt mean it is correct. I see alot of BAD info being pushed around here.
I have CM7 and run Fauxs kernels. I FORCE both CPUs online and run at 1.56Ghz. My standby is around 30mAH...Nuff said.
Something else is messed up. Chase facts, not fiction people.

and removing all the bloatware from the phone
but everyone has a different combination and im really confused as to which combination to use
right now im using eaglesblood 2.3.7 with the dragon kernel and its really not working very well

My opinion:
1. Jump on a stock-based ROM with stock kernel and UC (underclock to 900-800 Mhz, you would be surprised you notice very little change in performance). Most stock-based ROM users report back great battery life.
2. Jump on a CM7 Nightly 199 or higher (Reports of great battery life, I can attest to this) with morfic or faux123's kernel (I prefer morfic's) which you can undervolt easily with Pimp My CPU (search XDA). I prefer it to SetCPU because the only profile I use is UC when the screen is off and with Tegra's DVFS CPU governor, it already does a good job of doing this. I also UC with this setup.
Delete Wi-Fi Calling (Kineto.apk) from your phone if you're not using it. I learned this from lotherius, it's always running in the background even when off and not in use. I was shocked to see the improvement.
I know it sounds stupid, but if you're in class or at work and don't need a barrage of updates on your phone, just turn off data. Most ROMs have a quick toggle setting to efficiently turn it on and off quickly and you'll be quite happy with how long it lasts. If you have to have data on or think it's moronic to have an Android phone that's not does not always have a data connection, battery drain is just the price that is payed.
woah.
Awesome answer
so do you think option 1 is better or 2?
does using cm decrease the battery efficiency?
if it does do you think the extra functionality in cm makes up for the batteryloss?
Thanks btw

Good question, and I think that is totally up to you.
For example, my father and I both own G2x's, he runs a modified stock ROM (xboarder's ROM) and I run CM7. Without a doubt he gets better battery life than me, but at the cost of not having the features I have.
That may be a rough way of putting it but yes, using CM7 with all it's awesome features come with the price of not being as battery efficient.
The real question is if being less "battery efficient" actually means it's a bad thing. In my case it doesn't matter to me at all. Using the quick panel toggles in CM7, I only turn on data when I need it and I easily pull 15+ hours a charge because of it, assuming moderate usage.
Consider lotherius's tsugi rom, currently in version beta 3. It is my daily driver, stable, faster than 2.3.3 based roms, and excellent battery life. He has included a 2G toggle app that can automatically switch to 2g radio when screen is off to save lots of juice.

Hi,
having registered here some time ago i've been reading many threads about custom ROMs and the kernels used. Many of them seem to support overclocking your phones CPU. The thing i'm wondering about is that there's kernels which actually overclock your CPU to double the speed its CPU is supposed to be running on (!!), giving the CPU some more voltage i believe.
Actually i'm a bit sceptical about how setting the CPU to such sick frequencies has a bad effect on the CPU's lifetime. The way i understood the problem with clocking the CPU high is always the heat development, meaning without proper cooling the CPU will simply "melt away" (at least that's how it is on desktop computers). Of course, CPU's on smartphones are not cooled or anything. Now that there seem to be many people here, developpers or not, who got deeper into the hardware, probably already opened up a phone, or have some experience with the long term consequences of overclocking.
So my final question is: What is safe and what is not? I saw for the Galaxy 3 for example exist different kernels, some non-overlock kernels, as some kernels only doing limited overclocking up to 800 MHz (which seems to be the most healthy option to me), but also some kernels overclocking up to 1300 MHz, which as i said seems kinda sick to me. Well i bet there's someone out there with a bit more experience than me regarding this so i'd be thankful for any answer.
I believe its safe as long as you dont keep the phone at high overclocked spds all the time. Besides, this chips are designed to last 5 years at least so if you overclock and shorten its life, you would have already changed your phone. In short, dont worry, just dont leave your phone at above 1000mhz all the time

You got a point there hehe. Technical progress is moving in light speed. Anyway, i want to make my phone last as long as possible of course. But it's true, with CPU stepping it won't run on the highest frequency the whole time, even if overclocked, so i guess that overheating won't be an issue.
The only time i overclock is when im playing 3d games. Other times mine is 700mhz at most

No.. 800mhz should be your main profile. When charging i put 1200mhz 300mhz on demand. You shouldnt always leave it at 1200mhz. Only when you need it

if you use a governor like OnDemand/Conservative, your phone wont always be on 1200 but usually on the lower values...It will go only to 1200 when needed
I have a couple of question/advices I want to receive an answer for about CPU.
So I am struggling to get better battery life without hurting performance.
1) Can CPU apps hurt battery life by themselfs. I mean could only using an app not regarding the settings damage the battery life. Is it better to let the cpu work by itself and not any apps managing it?
2) Which is the best CPU control app?
3) Will Underclocking improve my battery life a lot and will it make performance worse. What are the best settings to keep battery life and performance optimized at the same time. If I want to play heavy games I will overclock for the time I play the game. But I don't want my cpu to be working at 1600ghz for instance when I am not doing gaming or similar heavy processes. What are the best settings to improve battery life but not hurt performance?
If you use an app like SetCPU, you can have profiles. I used to have it so that the phone would underclock when the battery reached a certain % or was too hot.
If you're S-Off and rooted, you can get way better battery life if you flash a new kernel. I'm using Faux v004, I've set SetCPU off and just let the kernel do its thing, and my battery life is at 1 day and almost 15 hours.
(I also play a lot of games and the Faux kernel is very resposnive. My games load much faster that they did on stock kernel)
Thanks! I am using this Kernel http://forum.xda-developers.com/showthread.php?t=1216197 and I find it good. I am rooted and used SetCPU in the past so I know all about profiles and etc. But my questions were. Do programs like SetCPU drain battery? And which best CPU program? And what about undervolting?

Apps like that don't really have any more of a drain than checking your email or receiving a text. If using Faux Kernel, there's an app out there designed for it that helps with clocking and undervolting it, made by the man himself. If not, AnTuTu has one on the market, I think.

1. Not really. I haven't noticed any extra battery drain with CPU apps so it's probably not significant.
2. I don't think there's a 'best' CPU app. I used to use SystemTuner, which worked fine for me, but I switched to SetCPU because I wanted to underclock the intellidemand governor on faux's latest beta.
3. Underclocking will lead to some improvement in battery life. As for undervolting, some people say it helps, others say it's a placebo; personally I've never bothered with it. You could try using faux's kernel with the intellidemand governor, which sets the clock speed (and whether the second core is online/offline) depending on the CPU load. As for best settings, it depends on each individual kernel and your own personal needs, so you might want to try flashing a few custom kernels to decide which one is for you.

Ah, learn something everyday. Whenever I sideloaded the apk on CM7, the author was listed as "faux123".

I know. I used to get confused too, especially since the app is called fauxclock! But faux mentions it's made by Romanbb on his kernel thread so... yea.
