How to extended the battery life time and minimize it's draining during your daily usage of the SGS2 ?
Also is. Over clocking. Increases the battery draining ?
To extend your battery life, stop using your phone and/or decrease the screen brightness when using it.
Overclocking will probably increase the battery drain if your phone is using the overclocked frequencies.
To increase your battery life turn your phone off every time you are not using it, turn it on when you want to use it, that will get you good battery life.
Honestly search this forum there are a handful of threads that give guides and tutorials on how to maintain battery life not that difficult to search my friend.

Use it as a paperweight and that should be good enough..Or just keep having the charger in it while you are at home
anyway lame jokes aside. get yourself a decent kernel. in your case speedmod. set the governor of your choice and let the magic begin......seriously for you that kernel should be fine. just do not get to excited when the magic begins and you start kissing your phone though just do not tell us here
Hope that helps mate

Speedmod is fine on default. No need to change governor unless you want to try conservative but I recommend to leave speedmod as is.

ohh u mean scaling of the cpu
oh yeh i never change that :L
its on ondemand now on setcpu
To be honest you don't need to use any of those type of application you are better off just removing them and leaving the kernel on complete stock.

Governors are for scaling cpu as you just said. As Nikz said if you are using speedmod no point using any cpu apps as the kernel does all the work for you

Ahh tried an earlier build and was fine but one thing I don't like about CM is the camera quality, I know it's not a digital camera but a TW rom produces better pics.

Am using bali now and it gives great battery life, but it is not as smooth as say... overstock. Is there any kernel which gives a balance between the two?
ones gotta give
Not sure what you're seeing but smoothness you're talking about probably has more to do with the rom than the kernel. If you flashed both kernels I'm sure you wouldn't see much difference between the two without the boot screen.

Did you try the overstock UV kernel? You can find it here:
http://forum.xda-developers.com/showthread.php?t=967861
It is the Overstock 1.5.2 UV download, it is designed to save battery life. You can also try SUPER_DragonMODz ULP, another battery saving kernel, here:

I literally just got onto the bullet kernel from Bi-Winning, and it has the smoothest i've noticed, but its only been a hour or two since i got on this rom with the kernel so... idk i cant say about battery right now.
I have to say, be careful with SUPER_DragonMODz kernel... For me it almost burned up my phone. Phone was just sitting on the table when I sense the burn The phone was hot as hell...
All dragonmodz kernels are great I ulp has amazing battery life, oc and normal both give me great battery life too with no overheat for me, wayyy less then bullet (has much higher voltage settings) just don't use any setcpu profiles (except for 400/100 screen off) and I suggest conservative govener

You might have something running in the background. Try to use Advance Task Killer. If it does not help, maybe you should flash another rom like Revolution Rom by Ali.

Also set a Profile in SetCPU when Screen Off do 400/100 smartass. I think it helps.
i will try...however the governor was conservative not ondemand...
thx to all
Might try calibrating battery. If so battery may be shot from improper care (i.e. leaving phone in hot car.)

Check how old your battery is. You might need to replace it. Or you can just ODIN back to stock and see how long you last on stock ROM and kernel and see if your battery lasts.
Don't use a setcpu profile if your using the smartass governer. it can cause sleep of death

I am running AOKP and before the stocks kernels battery life was not too good now I am running NEAK with AOKP 5-1 and I wanted to know which has better battery life. Siyah was amazing for me on GB with UnNamed.
EDIT: I tested Siyah for a few days it was pretty bad even with underclocking 200 - 800 or 1000 and with undervolt. Sticking with NEAK again just wanted to know if NOOP + ONDEMAND would be better or NOOP + LAZY.

Gotta try em both out, every phone is unique
Sent from my SGH-I777 using Tapatalk 2 Beta-5
Not just that every phone is unique, it's that every user has a unique setup with different app usage pattern. Different apps behave differently and consume power differently; therefore, my setup may require very different kernel setups to get extended battery life than yours might. As he said above my post, your the best judge of what works for your setup, try them all and see what works for you.

Same here. I came from siyah with horrible battery life.
I agree with Nick, try both.

Both performed about the same for me. I noticed significantly more performance from NEAK, and battery life is about the same. But that's just me.

Yes, but once again it varies per phone/user.
Also, what governor do you use? There's only 3 for neak and I've only used ondemand.

In N.E.A.K Options inside Recovery, you can enable two additional governors, as well as put Lionheart tweaks on the Conservative governor.
I find Lazy governor works well for me, but I'm still switching around. NEAK definitely gives me better performance, but seems to give me less battery life. More testing to perform!

How so? He asked about two different Kernels and how they performed. I advised "Both performed about the same" indicating I had installed both and my battery life was about the same. I don't see how I made a grammatical error in that.

Because you said "both performed about the same" then said "I noticed significantly more performance from neak". That's besides the point though

i've been using siyah...i get a lot of lockups with neak..but i think its because i'm not using neak correctly.
in the options is it better to have all governors enabled (conservative, lionheart, lazy)? also i hear for cpu that ondemand with bfq is preferred.
also does anyone have sched_mc and ext4 boost checked?
May you please post your i/o schedulers, governor, the way you charge it, and other essential info?

I had the similar problems (random reboots, lockups) with neak (AOKP), while running great on siyah / CM9 kernels. not sure what's caused it - was too lazy to figure out, reverted to siyah.

I had Siyah and battery life was not that great. I would leave the phone idle over night (5-6hrs) and it would go down about 20-30 percent. On the other hand with this new Neak kernel it only went down 1 percent. I can def see an improvement in battery life.
Hello, im on Temasek ROM with Temasek kernel, which can be customizable by stweaks.
I have searched but really didnt find an exact answer. Im looking for the values, profiles, that are best for battery life, yet dont want to lose much performance

you just contradicted yourself. You said that it does nothing for the battery life, while it clearly increases it. The actual effect depends on the underclock and your usage
What about undervolting? Does it save more battery than uc ?

I've already flashed two kernels in hopes of overclocking my Note 1. On one, it hung at the Samsung screen and on the other it booted (after doing something with each app) but kept showing force close messages that I couldn't close.
I really want to overclock my phone because it freezes a lot.
Also, I haven't had any luck with radios, either. These flash okay, but with dramatically slower speeds. Right now, I get on avg. 10 mpbs, but I've seen people with upwards of 50.
How could I do these things? Thanks.

I'm running Blackstar XI with AT&T. And I've only tried flashing overclock kernels, with no success. SetCPU lets me underclock, but the current kernel doesn't let me OC.
Kind of the same with the radios. I've only tried flashing them, with no faster speeds.
Are there other methods then these ways?

Well hopefully your flashing correct kernels for whatever ROM your running first thing ... And the 50mbps is probably due to the LTE speeds tmo released in a few cities .. Kansas is one I know of .....and over clocking isn't always the best ... I underclock myself to help save battery ... I'm not calling you a noob by any means but read up on android news and check our forums and you will fins your answers I promise

Alright, thanks. Maybe it's best that I don't OC it. Thanks.
I'm not saying don't over clock I just don't cause of battery drain ...... You can just watch CPU temperature and be careful ...maybe don't over clock to max just a little bit like 1600 or something

The only kernel capable of over clocking right now is ptmr3s kernel but I believe it only works with that hong Kong firmware. There are older kernels that can over clock but won't work with the latest cm merges. Like Shane said don't max out most notes can't handle it I never go higher then 1792. Over clocking is great but I don't think we will see a over clock kernel any time soon maybe look into scripts and tweaks.

I don't under clock because my battery life is acceptable and if my phone gets low I charge it whether I'm at home car wherever. do you guys not have to charge your phones every day?

Under clocking does not reduce performance. Mediocre gaming does not need 1.5ghz if you UC to 1.2/1.1 your performance will remain the same... Out of the extra hour of battery life that doesn't reduce performance its kind of a no brainer. Anyways stay on topic.
