Hi guys! After long searching, I found best settings for balance performance/ battery.
1) Install Oreo firmware 10.3.1.0. I installed over Pie fw after Rom installed.
2) Install IceCold Kernel v.3.5 Oreo. This Kernel have a underclock frequency (300Mhz) and overclock frequencies (1.8 and 2.2). You'll save battery and get best performance when play games.
3) Set darkutil governors for little and big CPU in your Kernel Manager. Set conservative if you don't play games.
4) Turn off ZRAM if you want save more battery.
5) Enjoy.
pS.: Sorry my bad english.
My rom is Evolution X 2.1
Appreciate your effort dude.

Doesnt 300mhz use same voltage as 600mhz? In that case it doesnt save any battery, just makes device more sluggish.

I dont argue about that. But that maybe because of other things you did. We shouldnt promote things that dont help, so just saying that people shouldnt be using 300mhz, it doesnt help
That's very useful tip bro... thanks...
But this trick won't workout for pie firmware based custom ROM I think
Yes. I reinstalled Oreo fw and run Pie Rom. This tip dont work in Pie fw.

No. Oreo fw is more battery friendly than Pie fw. 300mhz underclock is a plus only. This frequency dont work properly in Pie fw.

Its not about firmware.. Its about cpu architecture and voltage table used in kernels. SOC was designed to run at 600mhz minimum because its most efficient frequency. If you lower voltage at lowest frequency, it starts crashing and can be unstable. And since you cant lower voltage anymore, there is no point using 300mhz frequency, because minimum required voltage is the same as 600mhz, so you only loose speed..

I never said it doesnt run stable at 300mhz. I said it doesnt run stable if you lower the voltage. So now you are using 300mhz with same voltage as 600mhz uses, meaning that you use same amount of power, but completing task takes longer...

Can anyone modify it for G1?

They actually don't do the exact same thing... My kernel is undervolted, not underclocked. Theres a difference. Undervolted uses less power at the same speeds, underclocked just drops the clockspeed.

But the new Armv7 should be capable like the Droid,legend,devour,etc.
You can lower the vdd for 528MHz, but the next jump down makes it so low that the phone would immediately crash.

So we can lower it but not up it for the overclock?
Also, can we lower it at the lower speeds? (I have mine set up to underclock when the battery is low, when the screen is off, etc. so a lower VDD (if stable) would be great.

How feasible is it to underclock the phone even further than the 128 MHz?
personaly , i dont see a huge advantage to underclocking past what we got now, undervolting.... nah,
@ sleep mine atleast has virtualy no background processes.
and even on a heavy use day, cell standby shows up as my largest drain.
you want much better battery life, id say look into hacking the radio on it.
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.

Little tips : remove the cap of the battery BEFORE your tests ;-) in case the phone crash it's to easy for pull down the battery & reboot ;-)
1.4-1.5ghz is the max if you dont want to damage your processor
anything above 1.5ghz is very risky & gives hardly any performance boost
but mostly 1.2ghz is more than enough

I agree with that, anything over around 1.4 wrecks the CPU. The higher MHz are for Development testing and need not be used day to day.

There is an antenna in that "cap" as you call it, and there appears to be an issue with battery movement and the eMMC chip, you shouldn't remove the cap at all with the phone on to help prevent this.

first s-off then root the device then install a custom kernel that supports overclocking the use setcpu(from the market) or a similar program
you can control the frequency from setcpu
you can refer this guide

I tried at 1.8 ghz it hanged my cell. i think 1.2 is the safe limit.
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

It tends to get warm because CPU need to run quicker instructions.
If its sensation then bear with the slightly bad battery.
Because its a 1500mAh battery but needs to hold up a 4.3 screen.
Lower clock speed clean background apps before playing. It helps at least a little.

Hi,
It seems you are going the right way about it.
No 2 people use their phones in the same way,so battery life will vary,and there is no single setup that will work for everybody.
Keep trying different combination of ROM and kernel.
But give them a couple of cycles each,otherwise you will not see how they work properly.
