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.

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.

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

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.
I have a couple of questions regarding the ROM. First would be the CPU governor, I want to know which one is the best for the latest update, which is V13 RC1. I'm currently using conservative.
The second question is, how can I undervolt for maximum battery life? I've seen various people talk about this on other threads, but I don't know how to do it. Is there a tutorial for this?
Third and last question is, are there any other kernals which I can use instead of the kernal that originally comes with the ROM for maximum battery life? I'm looking for battery life, but that doesn't mean I want to completely get rid of performance.
Thanks again.
Have you tried letting your phone die fully then letting it charge to 100% because I know my until I did that my phone was only charging to 83%
Yes I did that already and have gotten positive results.
Sent from my SGH-T959 using XDA App
For the kernel I know passion is based off of CM9, so you could try a CM9 Kernel, but ICS is fairly new and the best governor that I have found is lulzactive and it is included in the stock passion v13 kernel.
There is an app allows you to edit the governor settings for lulzactive, I'm not sure how well it works because I haven't tried it out yet
is there a thread in which I can read about lulzactive?

Here's a post that describes and explains different governors.
And here is what the dev has to say about the lulzactive governor.
If you're having trouble with your battery not charging fully, then sometimes you just have to replace it. I had that problem with my old Blackberry. Try to avoid charging it before the battery runs low(under 20%), and also avoid unplugging it before it hits 100%. Those are just a few tips on how to improve battery health and performance.
As for managing the CPU, I kept mine on ONDEMAND and I get good performance and all day battery life.
Thanks guy!

I apologize for I know that similar threads have been created but the last one is fairly old. I have mostly been running AOKP for the last few weeks but I recently tried out serendipity- I'll say that I do prefer an AOSP style rom over a samsung rom. I do like customization but battery life is a priority to me. Can someone please give some input to what rom/kernal/governors are being used to maximize battery life?
There is no simple answer to this question. All Kernels and ROMs are good - please refer to Entropy's battery drain thread for common issues affecting battery drain.
Some kernels however offer UV ability e.g. Siyah which allows u more flexibility.
Having said this I saw about the same battery life on most of the ICS roms I tried.
I am currently evaluating custom GB roms to see if the battery life is better.

we've trained most not to say crap like that. its all dependent on user, apps, and device.
just play with them, find one that works best for you and your setup.
Would like to thank all the Beta Testers of my Elite kernel for Nexus 7. They have allowed me to see how low voltages can go in the device. Also, credits go to _motley, fosser2, Cpajuste, pershoot, catch1571, pinoyto, masterg0g0, morfic etc...and to who ever I missed. Biggest thanks to my wife for giving me the chance to do this.
UPDATED 10/19/2012
1. This kernel is updated to utilize the latest 4.1.2 by Google for Nexus 7
2. Same voltages applied as before to extend your battery life
3. Same speed of CPU and GPU
4. Same warning as below.

Now to the kernel
This kernel is basically a STOCK kernel with voltage lowered to the lowest possible settings to EXTEND battery life. No tweaks other than voltages
This are for Nexus 7 users who care more about BATTERY life and LESS HEAT than overclocking.
Here are the changes.
1. Undervolting is NOT POSSIBLE in this kernel. Undervolting has been done by me in the kernel
2. CPU voltages are default to maintain stability but it shines in undervolting the other aspects of the device, ie: pll_c, memory, emc, host1x, GPU 2d/3d bus etc...
2. vdd_core/vdd_rail decreased voltage from 1.2 to 1.1mv
3. emc, pll_c, host1x, GPU decreased from 1.2 to 1.1mv
4. Compiled using Linaro Toolchain
5. Speed of GPU 2d/3d/vde etc set at 400 mhz (close to stock of 416)
6. Backlight default decreased to 5 for better reading at night and decrease battery consumption
Here is the link OR CLICK ON THE BOTTOM
https://rapidshare.com/files/3373858690/ClemsynELITEBatterySaverStock.zip
WARNING:
Due to aggressive undervolting of this kernel. It might not work with your device. So please be very familiar with backup/restore of your device

I will use this as my daily driver when I'm not testing kernels.
Edit: I just realized that this is stock, I though it was like the previous 1.5 one of the series. Would you be updating on that regard in the future?
Edit2: Temp wont reach 40.0 C 37.0 C being the mac with none to light use.
Edit3: So has anyone tried to see if init.d support is there?
very nice!

If it works with the stock kernel, it will work with this.
Probably not then, you still have to modify the code to enable init.d support in AOSP source. Will give this a go anyway for the battery saving. Thanks for your work.
