Some kernels allow you to overclock the CPU and change the voltage settings. Sometimes it helps with battery and performance. Depending on kerenl can sometimes make the phone feel a bit snappier and smother. The kernel i usually use, and a lot of people is from ktoonsez. You can read about it here and get an idea

Any suggestions as to the best Kernel for CM Nighlies?

I've tried them all and the only difference is that with Koush's kernels the built in wifi tether works. Besides that I have not noticed anything different.
I think the built in is just fine these days.
Keeping in mind that i dont overclock, I think the built in kernel is the fastest (34's according to linpack) and most stable whilst KK's BFS #2 is the least stable.
When it comes to battery charge/drain... I have no clue.
I really wish we had more kernel devs. KK is busy with his sammy and no one else is making kernels for us that use the new tech i see in the other forums.
Are there any advantages/disadvantages for using a stock kernel vs a custom kernel? Thanks for the responses.

Stock kernel usually does'nt clock over 998MHz and you are'nt able to over or undervolt the kernel for better battery life.Also on custom kernels there are more governor options(smartass,etc.).Custom kernels can go up to 1118MHz sometimes higher,depends on the CPU.

I am aware of those differences. Basically, I'm wondering why I see so many people wanting to use a stock kernel (especially the one in the new OTA) and I was wondering why. Like what are the advantages of using the stock kernel over a custom kernel? Is it more stable? Are there any other things I may not be thinking of that would make a stock kernel a better choice? Thx again!

I would think stock kernels to be smoother because they are designed for that particular rom/build,when a custom kernel is designed to run on different roms/builds,then when roms are updated or changed,the custom kernel does'nt,unless changed by the developer,hence the lag and FC's.I hope thats the answer you were looking for.
Custom kernels are made universal for several devices and roms. Although they yield benefits over stock, sometimes they can be unstable on certain setups. like mentioned above stock is made specifically for said device bout somewhat limited, though very stable

Thanks clicked for both of you. Reason I ask is because I am running the new radios that were released with the newest OTA and wanted to know what to look for when I finally give the new kernel a try. Has anyone used the new kernel HTC released with the OTA yet? Has anyone a comparison they could share? Thanks.

Hey guys,
Still a bit noob concerning kernels so bear with me.
I am running CyanogenMod 9 on my AT&T SIII with their kernel. Would there be a lot of advantages to flash the KT747 kernel by Ktoonsez? Would it be faster?
If I flash this kernel, how do I go back to the CM9 kernel in case of problems?
Thanks!

Hi, I cant say it would have an advantage or be any faster or not because I haven't run CM9. I do use KT747 though. Only thing I can say is try it. If not you should be able to just flash your kernel back. Or just make a nandroid, which ya should do anyways
This thread is going to get closed pretty quick I'm sure. VS threads are not really cool to have and they all turn into personal opinion. You need to just try the kernels out for yourself and then decide. No one can give you an accurate answer for this.

Ok thx.
Didn't actually think to use the nandroid when changing kernels. I use it before changing roms but didn't know it worked for kernels too, which should've been obvious.
How do you find KT747? Does the undervolting make a big difference on battery life and/or performance?

Sorry about that. I've just never tried a different kernel before and I was feeling a bit insecure.

UV/OC is really different for each phone. I just run the default settings as is after installed.

Ok, I'll check it out in detail. Thanks.
2 options to revert kernel changes.
1. Nandroid before installing the kernel. Then only restore system when you want to revert. Its quicker than restoring everything.
2. Reflash the ROM zip. It will reinstall the system without erasing your personal data.

It's pretty absurd to say this. I understand that line of reasoning with ROMs, different roms do very different things, prioritize different ussage patterns, and apearl to different astetics.
Kernels are..... just Kernels. There are literaly only 3 metrics to judge a Kernel by:
1) Performance (how fast is stuff, this may or may not include overclocking).
2) Stability (self explanatory).
3) Battery life (also self explanatory).
There really isn't much subjective here. Some Kernels are just plain better than others. If one kernel is faster, and another has better battery life, then just say that. That's exactly the kind of thing that is helpful to all.
Hey,
I've been experiencing some nasty lagginess with my MIUI, and the battery drains shockingly fast. It happened after I installed a load of apps, since now I can, right, but the impact on performance is more than I can ignore. Obviously, I could uninstall some of the apps, but I imagine that's the whole point of rooting/custom roms, so how can i make browsing bearable/smooth again?
I'm using the stock kernel, 2.6.37 atroy, which would be the best kernel for MIUI-d2ext, or bravos in general in terms of smoothness and battery life?
I would have posted in dev thread, but am noob.
Try ManU kernel. Or Tiamat. Or CronMod, I had some issues with this latest one, it's based on ManU but allows more OC, but give it a go, you might be clear.

Yeh, I did see the first 2 as the most mentioned kernels, which settings did you and other people find to be the most stable? I'm not sold on OC for high scores in benchmarks, I just want stability.

Go for ManU then, or CronMod.
What really is the difference between all these stock type kernels that are "deodexed" I am specifically talking about the ones that Scott puts out that are basically Samsung kernels?
Am I gaining anything by upgrading these kernels when the new ones come out.
If I use an international kernel will that do anything negative to my United States phone?
I am running cleanrom 4.0.5 right now and just flashed an "L7" kernel, from Scott's website that allowed me to mess around with boot animations.

I usually dont mess with the kernel because I actually tried NOTE2CORE and that was kind of buggy for me my infrared light is always on if you know what Im talking about. the light next to the ear piece. I also tried perseus and saber and I did not tweak them or anything like UV or OC them. If you are crazy about OC and tweaking them those two are your best bet. If you are like me and cant really tell the difference in speed then keep it stock. I am running the new stock kernel MA4 or something. I am running CLEAN ROM also but the AT&T version 1.2.
Hope this helps and good luck
Best thing to do is search forums. This question has been answered many times. And there is some great guides already written on any questions you have about kernels. Thats how I learned and found a rom that I wanted. The info/guides will inform you much better than a post like this.
