What is the Best kernal for battery life with Undervolting Frequency Schedular SetCPU

Hey devs and users alike I was wondering what would be the best kernal to use to get great battery life, im fine with 12hrs+ although id prefer 18+ im using ava-froyov7 with netachys kernal. Any recommendations im willing to switch ROMS except for Cm6 since it is a SENSELESS ROM. Or any kernals that already have a low frequency governor Please post any recommendations.

Check out this thread it could be of some use. Look at maH drawn screen on and off could give you an indication of battery usage.

Custom ROM for Samsung Galaxy S

I am looking for the most fluent, battery efficient stable ROM currently available for my phone. I know I can search around though there are quite a lot of old posts and some unstable ones.
Any ideas as to what ROM I should install and any guide which could assist me?
For the record I have a Samsung Galaxy S I9000

This is the wrong forum for these types of questions....
However, you can have a look at my list of ROMs which should help (in my signature). Personally I recommend a ROM either by Darky or by DocRambone. I have found both stable and with good performance. Battery life will depend on how you use your phone, however there is an app called JuiceDefender which has double my battery life - I highly recommend it

I did.
I now have Darky's 9.0 Extreme Edition and Voodo 5.2 with the lagfix.
How can I convert my Voodo 5.2 to a OC kernel to reach 1.2 GHZ without ruining my Darky's ROM?. Also would the 1.2 GHZ CPU die out quickly? or will it run even more buttersmooth and have a great durability.

Answer
Answer please`?

I don't suggest to apply OC. It is not always perfectly stable, that means you may have crashes/freezes and a higher battery drain than a stock kernel(without OC).

Should be asked in Darkys or Q& A not Themes give the mods less work to do and more chance of a reply .

I think overclocking the device is potentially dangerous and unneccessary IMO...the ROM is already super smooth

[Q] Overclocked Kernels

Merry Christmas everyone! I hope everyone received all the tech goodies we wanted for Xmas!
I've noticed that most of the ROM's available in the development section already have an Overclocked Kernel and also UV options. I personally would rather use a stock kernel, or a custom kernel that is not overclocked. Right now I don't see that available from what I've searched for.
There are a couple ROMs I'm interested in running, but both install a new OC kernel. Is it possible to strip the kernel from the ROM before installing? And if so, does anyone know a tutorial for doing so, or is it as simple as opening the archive file, stripping the kernel out, and rezipping the file?
I know there are apps like SetCPU to change the clock speed on an OC ROM, but I really don't want to depend on software to keep the OC from occuring. I hope I was clear enough in my post to get the point across lol! Thanks for any assistance gents (and ladies).

Franco's kernels don't have OC

Thanks Josh! Appreciate your input. I am still interested in the other option as well, stripping the kernel from the ROM.

I am not sure how to repackage the from after you do that, but if you extract the rom the kernel is called "boot.img" and you can flash it in fastboot so you can basically flash any kernel you want on any rom

Just curious why you wouldn't want an OC/UV kernel, you're getting better performance and better battery life, no downside imo.

I honestly just don't like to OC my CPU's. In the long run it will decrease the life of the CPU.
Besides, if you have a great AOSP ROM to run, there really is no need to OC at all. Any performance boost from the OC comes at the cost of shortening the life of the CPU.

I've run Intel chips at 40% OC for a decade at a time, with little impact.
I don't expect my Nexus, with or without <20% OC, to last me nearly that long.
Just sayin'....

[Q] Which kernel work best for you? [subjective/objective]

Hey guys. I'd like to know what kernel you think suits you best. I'm looking for both subjective answers and objective answers. Which of the following suits you best?
Franco kernel
Trinity kernel
Faux kernel
Glados kernel
Stock CM kernel
Other
Please post a comment explaining why you have chosen the way you did. Feel free to discuss any kernel and also share your phenomenal tips and tricks.

glados for:
best compromise (for me)for performance\battery
fully featured like many others kernels but.....most of these features came from glados's dev,and then others dev implement it,love liveOC and is the unique with that feature,the dev is very gentle and available,the kernel can be adjusted via the control app,and IMHO is more good that trinity\franco's app for features,dispositions,colors,style etc.
i tried and used all the kernels and buyed all the dev's control app.my choice is glados,after 2\3 months of usage i don't want to came back.the best for my usage\tastes\preferences.
only 2 things that i miss:
a minimal slot of 190\220 mhz
preset pre-configured like franco's app (powersave,music,high power,etc etc..)

The kernel packaged with CM9 is faux, unless the CM team uses faux as a base and changes something in it..

Franco for me, despite some issues he is devoted to making his kernel perfect and his app is really good too for updating. Makes life a lot easier. With Franco's kernel I can say I have hardly ever had an app FC. I've tried other kernels but I just find with Franco's there is just more consistency and when I look at his thread I know what is going on almost instantly. This is my experience. I also like Fugu kernel and Trinity and GLAdos so on occasion I will try them out.

No Lean Kernel? Probably one of the most popular Kernel's out there

IAP Samurai kernel just rolled on the scene and couple of weeks ago. It's in the Sprint Gnex development section. I recommend giving it a try, Earthbound did some real good kernels in the OG Epic. Community and now he's brought his talents to the Gnex. It is based on Faux, but with IAP twists.

Currently switch between cm9 plus and leankernel. Both have a great balance of performance and battery life

I use the CMplus Kernel from here, he works with no problems under CM9 by me.

I completely agree. Franco/Lean kernel is the way to go. If I had more time throughout the day I'd like to try out the others again, but I don't feel like there's a need. Franco's kernel and app are great!

[Q] Upgrade Rom and Kernel

Hello everyone
First i want to congrats all the persons how make all this tutorials, they really help me a lot.
And now the questions, i already read the forum and the rules and i know i cant ask for compare any roms or kernel (http://forum.xda-developers.com/showthread.php?t=2097137) but i still need a few lights.
I need a kernel and a rom that help me save battery and can be fast enough for applications.
The last 2 i use was CM10 and FreeXperia kernel, and now i am using kernel vengeance and Xperia Ultimate HD 3.0. I test both with Antutu Benchmark and give me 4800 with Xperia Ultimate HD, and 5800 with CM10.
There is any combination Kernel/Rom that can help me make higher score and at same time save battery?
Many thanks

Welcome to xda forums.
It's useless to say that you have seen the rules and you still make this thread, the only answer that you should get and probably the only one you will get, is this one:
TRY yourself each ROM from the Android Development forums, and then you will see which one suits your needs, and serves you the best.
Also, don't forget that AnTuTu scores aren't 100% reliable, and they're based mainly on Governors, I/O schedulers and CPU Frequencies, it's not that reliable because I myself get better gaming performance with a Governor that gave me 5300, than with one that gave me 6000, they are just numbers.

Like above post said, try out the different ROM and kernel combinations yourself as the resulting performance is different for everyone because of the different settings you use and the different apps you install on your phone. If you want to find the most suitable kernel for your phone, check the ROM thread. Each ROM thread should have a list of recommended kernels that will work best with the ROM. For example, Jader recommended LuPuS kernel for his UHD ROM. However, if LuPuS does not work well for you, you can always try out other kernels in the recommended list. It differs with each user.
As for benchmark, it only gives a general idea of your phone's performance. It is not accurate enough to genuinely gauge phone performance. The one who determines that is yourself. Only you can tell if the performance is good by trying it out yourself.

Thanks for the replies.
I did like both sugested, trying. I tryied a ICS Rom and i didnt like it. So far the only one that i like most was CM10.1, the kernel i use was the included in the Rom. Work all allrigth.
Anyway sorry for the questions, i just wanted to make sure before starting flashing my phone.
Thanks

i use Xperia Z Jelly Bean v3 with Lupus kernel battery life gud.. but make sure you have swap of atleast 500Mb or you might get reboots with some apps(i had reboot issues with FB and some games while used for long period only but since swap 0 reboots)
