[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] Galaxy Nexus: Kernel and ROM

Hello xda-developers.
My name's Mirko and I from Italy. It's my first time that I post in this beautiful forum of all kind of developers
I have Galaxy Nexus (GSM. Italian version) with Android 4.1.1 stock. My small questions are:
- I suffer from short battery life, it's better change kernel or ROM?
- If it's better change kernel, what you can recommend to me and why?
- If it's better change ROM, what you can recommend to me and why?
At the moment only these are my questions.
Thanks for all answer.. It's my first time that I unlock bootloader and root my device (I have to do it), and I'm a full newbie of modding
Thanks thanks and thanks, this forum is the best.. Keep on the fantastic work and congratulation to all modder, staff and all!
P.s. sorry for my bad english
Best Regards.

Before you do any of the stated you need to find out weather your phone is gsm or cdma because you CANNOT put a CDMA on a GSM phone or the other way around.
Kernels affect battery life. I recommend Franco kernel or Lean kernel
Roms affect user interface (the OS operating System on the phone) - I recommend for a starting stable rom Cyanogen (its what MOST roms are based off of) then if you want to tweak your phone more I recommend CodeNamedDroid or ParanoidAndroid. (these are the three that I use the most)
also i would recommend this thread about battery life http://forum.xda-developers.com/showthread.php?t=1599025
i hope my english has not confused you. Dont be surprised if noone else responds to you in this page, they have a bad habit of doing this.

Hey Weapondrift, I realize that maybe my Galaxy Nexus is GSM.
I give a watch to Franco kernel or Lean kernel but all say it's better both.. Don't know what the difference before start my first flash.
Thanks for roms..
What do you think? It's ok only kernel or it's better change rom?
Thanks for battery life thread, I'll follow
No no, your english won't confuse me.. I can understand but I have problem with speak to other
Oh.. Really they have this bad habit?
Thanks for you answer, friend
Best Regards.

Franco's has horrible battery life...
paranoidandroid with trinity is the best imo

Yes, custom kernels can improve battery life if you're willing to trade in a little performance. Can't have both at the same time.

I beg to differ..
I find trinity performs just as good and adds like 2 hours screen on time

Benefit from custom roms like Omega and ARHD

No offence to any of the developers, i respect your work !
Im just asking, what are benefits of installing Omega or ARHD ?
I want to keep stock-like rom (because of full functionality of spen etc..). And ive been considering option to flash stock-like custom rom (Omega, Wanamilite, ARHD). So i wanted to ask you what are real benefits with flashing those roms ?
And can you tell me the difference between ARHD and OMEGA (i see some difference from op threads but i cant seem to find big difference )..
Thanks in advance

I am personally using WanamLite V1.5 with RedPill Rev 0.6. The benefits are that i was also looking for a stock based rom to keep all the phones original feature like Spen etc. The WanamLite rom, its stock based and adds better performance to the device. Also the RedPill Kernel further boosts performance while also boosting battery life. My $0.02 cents.

Are u experiencing keyboard lag on custom roms ? Its killing me on stock rom ...

To be honest with you, your best bet to get any information is to do what everybody else does. Pull up the post on each ROM where it tells you the features each ROM has then you can compare all 3 rom features and make an informed decision on which 1 you want to install. No 1 is going to do that for you.

And i will add...read the threads of each rom.That way you can get a feeling for each rom.Level of support,problems and how friendly it is.
Then as therockk says...make your choice.

I remember back when single core phones running 1000Mhz were considered fast. People were really happy. That was about 2 years ago.
Now, we have quad-core phones running 1.6GHz each core, and people still want better performance?!!?
I haven't seem much of a difference between stock and custom ROMs for the latest few phones (GNote2, S3). Look at the good things about these phones instead of the minor little performance "issues."

Stock rom and stock kernel are pretty good,especially the kernel. But i have a rooted device....i want to test the extremes...custom roms and and custom kernels give that opportunity.
Just my take but Androids not about just accepting...it`s about reaching out.

Thank you for all your replies... I decided to stay stock .. Because it fits me best. I have everything i need and performance is good.. Battery life is great..
I rooted my phone and did custom cwm just to mod it a bit... Thats all..
Thanks again folx

[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)

[Q] Best Kernel

Hi Developers! what is the best kernel for stock rom jellybean of ace 2?

Chrono kernel is probably the best. You can find it in Galaxy Ace II Android Development forum.

You're right ! all my games is smooth now thanks buddy.

I don't like custom kernels... Chrono kernel doesn't work that good, it drains a lot of battery and dunno why. Just go with stock

You obviously dont know what version to use/ how to configure

well, with my daily usage i have about 22-24 hours with TC stock kernel, and about 14-18 hours with Chrono 4.4 F2FS. My settings are pretty simple: 100/1000 mhz interactive, sioplus, -50 UV (can't go any further), GPU -100 UV with 192mhz. It's smooth with both kernels, but chrono drains more.... i just like F2FS, i wish it was for /system partition too

Mod Edit
"Best" or "Recommend" ROM / Kernel threads are not allowed on XDA.
Please test these things for yourself. That is the only way you will get an unbiased opinion,
and then, you can decide for yourself if it meets YOUR needs.
