What are your guys' opinions on the performance of these two kernels? From what I've gathered it seems like KToon's kernel is meant for overclocking, but then what would one use task's for?
Task's recent update to his kernel makes me want to try it because I've been using KToon's kernel with the ktoonservative governer and row scheduler UV'ed a little bit but unlocked to 2.1GHz and have been having some pretty bad battery life in mu opinion, do you think switching to task's kernel would be better on the battery?
Well what do you guys think?
Fun Fact for the day. Versus threads get shut down in no time here on XDA.
P.S- Why wouldn't you just try it first before making a thread about it? Kernels take about 3 seconds to flash. Also. No one can tell you that you will get better battery life on one or the other considering all of the variables. We are all in different locations, use different apps, have different settings, and we all use our devices differently. You need to try them both out and see which one works better for YOUR device.
Man why are ya giving me a hard time? You kicked me out of your thread, which I understood and respect, but then you come here and tell me the same thing you told me before and that my thread's gonna go to the bin in no time.
I'm just trying to find out what the DIFFERENCES between the kernels are, because it isn't very clear in reading the descriptions/OP's,
They wouldn't co-exist if they were exactly the same.
I'm not too interested in tweaking the hell out of my device nor do I care too much about overclocking...I just want a lot of screen time and the ability to play games and SMS with little lag.
I have tried out both kernels and didn't really notice much difference because I didn't really know what to look for.
Like, okay or example, it seems to me that your kernel is less for tweaking and isn't for overclocking (max 1.6GHz or something?) while KToons can go to 2.1.

I'm not giving you are hard time. I'm just telling you the facts here. If you're not into tweaking and messing with things then this is simple and really shouldn't make a difference to you which one you use other than battery life, less lag, ect... Which no one can tell you one is better than the other for. Flash one and don't touch the settings for it and use it how you normally would for a day or two. Then do the same for the other kernel. See which one gets you the best results. Its the only way to find out. Not quite sure why you're refusing to take my advice here. Its pretty straight forward.
There's kernel source in both threads that explain in DETAIL all the DIFFERENCES between the two. It literally only takes seconds to flash and see for yourself. This shouldn't be a big deal at all.
I think they re two of the same.Task just doesnt want KT to know he borrowed his kernel...lol jk. But seriously,they're pretty similar.KT seems better on the performance end but I never got the exceptional battery stats that ppl keep posting,IdK it may be something on my end. On the other hand, task's seemed better on my battery as I could not noticeably see my battery drain during use as I did on Kt's. Furthermore my phone does get hot really fast on task kernel,I'm guessing its cuz we use performance control and can't really play in the voltages as much.

I have flashed both kernels. And I don't mean that I am not planning on doing ANY tweaking whatsoever, I just don't mean like messing with voltages adding or subtracting 25 at a time until my CPU crashes so I can find the under/overclock limit...that's the kind of tweaking I have no interest in trying. I'm not gonna look through he sources of both kernels, come on dude you know I'm not a dev and that level of detail is un-necessary.
Your kernel being capped at 1.6GHz probably is better on battery but I also have a sixaxis controller and like to game, does it affect 3D performance at all?

This is the kind of posts I'm looking for in this thread. Do you personally find task's kernel's performance to be any worse than KT's? Cause you said bettery life seemed better.
Also, are the same governers and I/O schedules available between both kernels? The only settings I'm used to using is ktoonservative and row, I wouldn't really know what to do in performance control to emulate what I've done in KTweaker.

He cannot answer this question honestly. He doesn't have your device. You're not understanding. He can have the best battery life possible on my kernel but if you use it, you could have the worst battery life possible. IT'S DEVICE DEPENDENT. Will you please just do yourself a favor and take 3 seconds, flash the kernel, and see. You say you've tried them both, but you are also asking about playing games and what not with them? You would know if you had tried them dude. Same goes for the governors & schedulers. You would also know that if you had actually tried them both. I need to ask you this. Why won't you just try them and see for yourself. Are you really the type of person to flash what people tell you to your expensive device?
Look dude. I'm only trying to help you here. I'm not quite sure why you wouldn't just take my advice here. I have quite a bit of experience with this stuff and I'm trying to help you get the best experience possible. But it seems as though you think that personal opinions of others are whats best for your device when in all reality they are not. Real life testing is what will prove to be best for your device. Trust me.

What You won't have on underwear kernel vs kt747: ktoonservative gov, vibration strength control, screen off max freq control, screen off gov control, fast charge, MHz range from 96 to 2106, undervolting capabilities and adjustments to governors and schedulers.
If you don't want to undervolt or tweak anything, I recommend you use underwear kernel. It is stable fast and oc to 1674mhz is alright for any gaming and it doesn't affect 3d performance.
If you wanna use ktoonservative governor then you will have no choice but to use kt747.
But anyway, what you really need is to try both and familiarize yourself with their features.

Comprehensive list. I like it. Now I gotta figure out which gov I'm gonna use when I flash the underwear kernel.
Thanks everybody for their input, if anyone else has anything to say then please go for it!
Wiping cache + dalvik and flashing underwear kernel then fixing permissions and rebooting and gonna take a look around performance control to see whats up.

Here is some info on Governor and I/O schedulers. Obviously it isn't going to include Ktoonservative or ROW but you get the idea.

Hi guys, i've been looking into many threads and reading a lot of posts and asking a lot of questions. however i know that their is not for sure answer to this but i would like to see what you guys believe to be your best kernel for battery and performance. i have seen people say it is Godmode (v9), Tiamat v4.1.0, Tiamat v3.3.7, and Savaged-zen v2.2.1. (ALL of these ARE with SBC-OFF). i just want to know what is you best kernel at the moment for your evo with decks or cm7.
Side Question: what is the difference between the governors: (Interactive, InteractiveX, Smartass, SmartassV2, Savaged-zen, and Lag Free)?
- Thank You
I like Tiamat 4.1.0, but I can't help you for your side question. I'm still new to development and rooting

i know you said your new but im just wondering have you tried any other kernels?
and what is your battery life with Tiamat 4.1.0
I've used damn near every kernel available for CM7. And by far the BEST kernel for battery life is Savaged Zen. I'm on a stock battery and it just seems to last forever. Add to that the fact that the battery lasts all day without sacrificing performance at all. Every phone is different and you may or may not see the same results. This is just what has worked for my phone. Honestly, your best bet is to get flash happy with various kernels until you find one that gives you the performance and battery life that you're looking for. By the way, I use SVZ Manager with my kernel so that I can toggle SBC on and off as I please. It's a nice apk that gives you some flexibility.

I've tried Tiamat 4.0.8 and a Savaged Zen kernel (can't remember which version). They both gave me about 12 hours of battery life on an average day(for me). But an average day for me is going to school, so I'm not on my phone as much. I haven't gotten to really test the battery life because I haven't looked at it on the weekend when I'm not at school. But like Concordium said, every phone is different! Try them all!

at the moment i am using the latest svz kernel with the svz manager as well. i have been flashing many kernels and for a while i was happy when i used the godmode kernel my phone lasted me 1 day and 6 hours, however he is no longer updating his kernels =( i'm hoping to find another kernel such as that one that will give me around the same results ^_^

well im testing this one out at the moment and it has given me so far 17 hours and 20 mins, still at 31% battery, im just not sure if it'll do better than godmode did, at the moment im running it on the smartass kernel and i ran godmode on interactive so maybe that is the prob... however another issue is i've heard that svz is no longer updating as well... do u know if this is true? and one random thing that only a few people have told me is that they run on performance and overclock their phone and get the best battery from it, is that possible or a lie?
Edit: it lasted 20 hours and 53 mins, so since it didn't do as good as GodMode did then im gonna try the tiamat 4.1.0 now cause it has first place in the poll atm.

Its true that its not being updated anymore. It sucks but I plan to ride it out as long as the kernel functions properly with CM. Once it starts screwing up then I'll switch.
Those who say they get the best battery life by overclocking and putting their phone on performance are full of crap. Performance governor is basically the polar opposite of Powersave. Performance keeps your cpu constantly running at a high frequency. Logic states that overclocking to 1.13 ghz and perpetually running at that frequency requires more power than running at 245 mhz. The more power required the less time your battery will stay alive. Powersave gives you best battery life but gives you crap performance. Interactive, Smartass, and Ondemand give you a balance of performance and battery life. Performance gives you the best performance but crap battery life.
By the way, do you really need a phone that can stay off the charger for more than 21 hours? :-x

no i do not but! 3 days of the week im at school doing nothing for 8-10 hours so... i think if my phone can run longer than a day w/o charging then it mean i can play games on my phone while waiting and by the end of the day i'll still have battery. and does it make sense for someone to get better battery life on interactive than on smartass?

Well Smartass, as I've heard it described, is sort of like Interactive 2.0. It's basically the interactive governor but better. Unfortunately, I do not know enough of the exact specifics of the governors to tell you which SHOULD be getting better battery. I would just run each of those governors and see which one works better for you.
And I thought your phone already lasted 21 hours with a decent amount of usage. You need to test the governors/kernels in the exact situation you are going to be using the phone. Interactive, Ondemand, and Smartass would all manage the phone pretty much the same if you just leave it alone and let it sit till the battery drains. but they each manage the power allocation supplied to the cpu very differently during actual use. One ramps up the voltage quickly while one scales it up more gradually. So take your charger with you to school, in case you run into trouble, and use the phone as you believe you will be using it in the future. Then you'll have a more accurate idea of which setup works best for you.

just wondering what do you keep your cpu settings at: the governor, cpu min & max?
When I am plugged into my wall charger I keep it at 1113/245. I use Performance for benchmarking and testing since I don't need to worry about battery life and Smartass when doing everything else. For normal every day use I have it at 1036/245/Smartass, Interactive, or Ondemand. I don't really have a preference between the three governors since they all make my battery last more than long enough. So it usually comes down to whichever my clumsy finger happens to accidentally select first. If I happen to not go home and need more life then I'll drop to 729/245/Conservative or Powersave. I use conservative if I still need to be able to use the phone a bit and powersave if I want my phone to just sit there and look pretty till I get back home.

You're not bugging me man. This place exists so people can ask questions and get help.
I keep my min at 245 because I've read, in multiple places, that allowing it to go any lower is not something your cpu really appreciates. Just like there is such thing as too high with your clock speed there is also a too low. And everywhere I have seen 245 is the preferred low end. I am not 100% sure as to why but I would assume that it is because your cpu needs at least a certain amount of power to run the basic processes required to keep your phone functional. Similar to a computer. Lower the cpu too much and it just can't do what it needs to.

I don't remember there being a thread dedicated to this. I just remember it from posts I saw within different OC/UV threads. Do a Google search for it and see if that returns any results.

With Tiamat 4.1 and juicedefender I get the best battery performance and v6 supercharger I have a smooth screen with no problems or lag at all.
I am running CM10 M2 on my Samsung Galaxy S3 I747
Now my question is which kernel do i use because i would like to OC my phone but it has to have some speed and keeps some battery life.
I don't want to have a lot of speed with hardly to no battery life, i need a little speed plus good battery life if possible.
So if anyone has any suggestions please post

You can try all that work with CM10. It's a preference thing. I'm using ktoonsez. You can OC and UC.

Im not saying there aren't any others as i have only used ktoonez's kernel, http://forum.xda-developers.com/showthread.php?t=1756776 simply because there is, IMHO, no need to. He has versions for each of the available android versions for the i747...obviously you would want to use the AOSP JB based kernel under CM10. Packaged along with the kernel is ktweaker which is an app that gives you control over the clock speeds, under volting, governors, schedulers, plus a bunch of other options. If you overclock your processor you are going to drain the battery faster, you can compensate for this by under volting the frequencies however pushing the CPU too hard can shorten the life expectancy and under volting too far will cause severe system instability. Im not sure how much experience you have with OC/UV'ing but its basically trial and error until to find the right balance of speed and stability that is right for you.Just be sure to read and follow his instructions carefully and dont mess with anything in ktweaker you aren't 100% sure what it does, and as always make a backup in your recovery before messing with system files.....happy OC'ing.

There is a thread dedicated to ktweaker settings on the i747 HERE that would be a good place to start and get an idea of what you are doing. There are also several topics that discuss the different governors and schedulers, what the differences are, advantages/disadvantages to each etc. You can also search google for a plethora of information regarding OC/UV'ing, although most of it will pertain to desktop processors and video cards. While the voltages and frequencies will be significantly lower the same principles apply with mobile device chips.
Hey I want to know how KT747 kernel works with AOKP Ktoonsez and Task650. From what I hear its pretty good. My main concern is battery life. I heard some people get around 5 hours of onscreen time which is incredible. If you are running these two together, what are good settings for good battery life? I'm using KT747 with CM10 M2 and Ktoonservative/noop but battery life is kinda bad. Thanks
I'm running that setup and although i can't really compare my battery stats to your as i have a 4400mah battery, i can say that for my phone atleast the battery life is superb. I actually just plugged it in after 67 hours, with about 7 hours screen on time. Obviously this isn't going to happen on a stock battery (mine came with a 2100mah), you could realistically expect a little less than half these numbers. I would suggest taking a look at this thread, which discusses overclocking and undervolting settings. I have posted pics of my personal undervolting settings (page 15, post 150), however your device may differ. I discuss why and my suggested method to finding the best value's for your device in the same thread, post 152 on page 16. Of course the discussion has many other opinions and suggestions as well so try them out until you find the one that works best for you. One thing i didn't mention is to disable the cpu settings in the settings>rom control>performance menu as it will conflict with the settings in ktweaker and can actually drain the battery much faster than normal.

Thanked*. Will take a look at the thread. Last time I undervolted I used some guys settings which were extremely wonky and cause a lot of mishaps. I'm still looking for good ones so I might try yours. Thanks.

Sounds like too much undervolt.

Just tried it, it was a little to much so I bumped everything up a little bit. Seems fine now. Going to flash AOKP later today.
Thats actually how i got those settings, i used what someone said was stable on theirs. It wasn't, playing pretty much any game on my phone would cause a reboot in less than 5 minutes. I think i ended up about 20 mv higher on all steps than his settings. You just have to find what works for you phone.

Indeed. I have AOKP with Ktoonsez/sio and voltage a little higher than yours. Works fine, battery is good.
I have recently switched to the noop scheduler after an article i read which basically said there is no need for a scheduler using flash memory. All the other schedulers are designed for physical hard drives which have seek times, flash does not. Using these schedulers actually creates an artificial seek time, thereby wasting cpu clock cycles and burning precious energy in the process.

Was always on noop and ktoonservative. Most people recommend those two together

I think its pretty good. I find it more stable than other roms, imo.
KT747/Cm10 m2
Hi,
I installed Cm10 m2, then ran it, rebooted, and installed kt747, cleared caches and fixed permissions, could not boot afterwards, Anyone else have this problem?

Hmm, I've never had that problem with KT. Make sure you have correct version, AOSP JB. I would recommend flashing CM10.0.0, the latest CM10 stable build.
Hey all, I am running KT747 Kernel on Liquid Smooth ROM. I just have a few questions about kernels and tweaking them (and yes I do know about THIS thread, but it is very cluttered)...
1. What is over-clocking/under-clocking and what does it do? Also, how do I do it?
2. What is Governor and I/O scheduler and what do they do? Also what are the differences betwteen all of the Governors and I/O Schedulers?
3. How do I tweak my kernel to get a really good benchmark score?
4. What are the voltages?
If you can answer any of these questions I'd greatly appreciate it. Thanks to all!

If you read the OP of the Team Kernelizer's thread it'll answer most of the questions.
1. over-clocking/under-clocking refers to adjusting the speeds which your processor is allowed perform at. Over-clocking means that you can set it as a higher speed and under clocking is that you can set it at a lower speed.
2. There are many different threads on what each of the govenors and schedulers do. In the OP of ktoonsez's kernel thread there are links which give pretty good explainations as to what each of them do.
3. Tweaking your kernel is going to be something that is pretty much dependent on your phone and finding the proper pairing for your phone of frequencies, govenor, and voltages for each individual frequency step.
4. The voltage settings are how much power the processor is allowed to pull while it's at each individual frequency step. These can be changed to optimize performance as well as increase battery life. undervolting too much though could result in issues with your phone.
All of this is very much trial and error.
In order to change any of the kernel settings, use the ktweaker app that was installed on your phone when you installed the Ktoonsez kernel. The app should be in your app drawer.

Thank you! I already know about the Ktweaker app as I've used it already because I followed the steps in the thread and tweaked my kernel already for the "good battery+performance" setting. Although not gonna lie, I did not know what I was tweaking lol. I do notice amazing battery life though... after those tweaks I got 60hrs with 3 1/2 hrs of on screen time (4200mAh extended battery). I just wanted to clarify what I was doing. Plus I always hear about over-clocking/under-clocking but I don't know what it is or how to do it.

Over/under clocking and under volting are explained/described pretty well in the OP of the team kernelizer's thread. That being said that sounds like some pretty great battery life.

Ever since I did those tweks I've been averaging 2 Days 12 hrs (60hrs total) per charge.... freakn awesome!
Thanks for the info, answered my question as well =p

Theres a ton of good links in the following thread too

As for CPU governors and stuff, you want the "setcpu guide on how to use" and "android governors explained" links
I'm running SOA B2 with their kernel, in performance setting it allows me to go up to a maximum of 1836 MHz, is this safe?
Will battery life worsen?
Should I change the governor or I/O scheduler?
If you know what any of it means, it'd probably be best to stay away from it.

I have many app ideas, but don't have the skill or the time to learn how to make an app. if you would like to know an idea and attempt to make one, just message me.
Listen arianaLarge, don't bother replying if all you are gonna do is talk ****. Help the rookie out. This is a place for learning and contributing, its a community, it does not belong to you.
Having said that,.....you will lose stability and battery life if you go that high.
You will gain considerable performance but for what really?
Do you need it, probably not.
Personally I underclock to 1.18 for 80% of the day during the week, and run at 1.67ghz all day on the weekends. Its very easy to kick it up higher if you need the performance boost.
Also educate yourself on the various governors to better manage your CPU draw.
Google is your friend and the greatest tool you have for information.
Use tricksterMod or system tuner in the play store to manage CPU states and governors, both are free.
Both are great
there is no spoon.....
I never touch my CPU settings and use stock rom kernels....I've never seen a significant reason to bother with changing things. And I've never had hardly any of the problems I read in the rom dev threads.
Just my two cents.
Sent from my cell phone telephone....
Make sure you don't click the save on reboot button (or whatever it's called) because you may end up in a boot loop until you can flash some recovery to reset the setting. I don't think you're at too much of a risk, but the phone may not run stable and will likely shut down if it's pushed too hard. That's what I think.
Yes the battery life will be shorter. It may not be drastic unless you are constantly using it because the CPU speed will go back down when you idle.
