I've never had a problem with the KT747 kernel, but somehow the latest build (9/18/12) is giving me huge battery drain and I'm thinking of switching to the latest faux (v013) kernel because I don't wanna go back to stock. Keeping battery life in mind, what would you recommend between the two and what version of that kernel? (or three if you're recommending stock kernel) Thanks.
On a side note: I'm sure that there is no rogue app or some other mysterious problem sucking out the power because I made sure to check w/ BetterBatteryStats, and the app is pretty much accurate for me.
Did you wipe cache/dalvik cache? The 9/18 update gave me a significant improvement with my battery life.
Newer release of KT747 out as well. I can't speak about Faux's kernel as I haven't tried it.
Im with the Op on this one...the 9/18 kernel is not 100percent right ..but the one before that i think 9- 12 or 13 is the one im using now and it works great!
I love the K tweaker i uv by 50 on all mhz and have no problem oc'ing to 2.1 all day i use 192 min 2106 max ondemand with juice def ultimate and with moderate use get 18 or so hrs and great quadrant scores altho they dont mean **** lol but here they r hope this helped

So I recently been running KT747 kernel on my GS3 with AOKP JB M1. Battery life is ok (all settings default except for I/O=noop, Governor = Ktoonservative). I found out that the T-Mobile GS3 LeanKernel also works on this. Has anyone tried it? Is it good? Heard most people get good battery on it, but then again it varies from user to user.
Edit---*
Tested out a few different settings. I under volted using the mv's listed in the original KT747 thread... phone rebooted constantly, guess my phone can't go volt down too much . I'm going to run deadline + ktoonservative for a day and see if it's any better.
In all reality no one can answer this for you. If you think about it, we all have different settings, different apps on our device, we live in different locations, and we all use our phones differently. So one guy could say he gets awesome battery life on ktoonsez's kernel while the next guy says it sucks. That's just the name of the game. All devices are not created equally especially in realm of the kernel world. There are just too many variables. So asking this unfortunately will not get you any closer to your answer. You just gotta take a few minutes to try them out for yourself to figure out which works best for your device.
Do you know the difference between Ktoonservative and Conservative Governor?

I definitely do. You should also. You just need to take a little time and go through the OP of the kernel thread. All the information you need/want is right there. look here dude
I've tried a few kernels and I always go back to the CM10 kernel it gives me by far the best battery life out of every kernel out there that I have tried.
Even with the SGS2 i9100, CM9 kernel was always my favorite, just because of how superior the battery life was.

Thanks so much, didn't read his Extras post. I also looked up what each governor does earlier, and realized that there was also Ktoonservative which wasn't on the list I was reading. Thanks for the answer You're one of the nicest and most helpful dev's out there task.
I found CM10 kernel's battery life to be a hit and a miss. Some days it would be good, others would be bad. KT747 has been more consistent for me

Definitely not true. Those settings are good for your device. It doesn't mean it will be good for him. Every single device reacts differently to different settings. I've gotten horrible results with those settings if that says anything. That's the thing about this device and kernels. They all take well or worse to different governors, schedulers, voltages, etc...

That's an interesting post to mull over. One would think because Samsung rolls out the same Chips with the us version that you would get roughly the same results, I had heard about the voltage differing (because of the silicon thickness). but not about phones reacting differently to schedulers and governors. This will require more looking into! I do enjoy a good read. Thanks for correcting me, I do like to get the facts straight before helping others.
But putting user use aside(what you do on your phone), if your phone was 100%-0% idle you should expect the same (roughly) result when using the same govs& schedulers as someone else with the same phone correct?

Yep. It kinda sucks that they differ so much between devices. It varies so much that some people can't even use ktoonsez's kernel at all. Some of those that couldn't use his kernel in particular returned their device for a replacement and then were able to use it with their replacement. Its pretty unfortunate in my opinion.

The CM Kernel SUCKED for me!!! My phone ran really hot w/ not too much of a load on the CPU & my battery life sucked!!! I use KT 747 w/ some undervolting & it runs GREAT now!

I am giving Lean Kernel a shot after having ran KT747 for a few days. Not sure why but my phone didn't take too well with KT747. Too many random reboots and what not. However my battery life (even with the reboots, etc) was awesome. I say give both kernels a try. That's the only sure-fire way to see if you device likes one better than the other.

Sorry been sorta AFK with this post, man those are some crazy results. But as Task said, differs from every device. I've used other people's settings and have gotten horrible results in terms of battery life and random reboots. I only get around 3 hours of onscreen time which makes me a sad panda, but I'm still changing the effects constantly. I found that leaving stock voltage actually got me better battery life.
I've tried both kt747 and leankernel and found both seemed better than whatever the stock kernel in Slimbean is. For me, LK seems to work better and I am getting great performance and battery (15 hrs battery with 4hrs of screen, 24+ hrs with light usage). LK uses SIO/InteractiveX.
Thinking of trying out ktoonsez and task's AOKP...hearing good things and have not tried an AOKP ROM yet since rooting my phone.

I've used both task's AOKP and the official rom, both are good. For me, LK+KT seemed to be almost the same, but I believe LK had lower idle consumption, despite KT having a limited mhz while screen is off option. I don't like slim bean too much though, just preference.

Undervolting isn't meant for battery though, people who undervolt usually do so for two reasons.
One, extending cpu life span
Two, less generation of heat for overclocking.
Yes undervolting does effect battery life but it is so small that is really wouldn't make a big difference.
As for adjustment results yes there are a lot of factors. they mainly have to do with what the users does while using the phone. As well as settings for brightness, backlight buttons, etc. That is how everyone differs. If your phone sat idle 100 to 0% you should (roughly) get the same results as someone else running the same set up. But then again who the hell does that anyways?

I enjoyed LiquidSmooth a lot, but I wanted to try Paranoid Android for a bit, so I'm running that now. Forgot to update my signature. LS is really smooth, one of my fav's next to AOKP.
Hi guys,
I've got a Galaxy S3 via Rogers, rooted, running the rom Triune II, I haven't messed around with custom Kernals (tbh haven't figured that out really), I recently installed SetCPU to overclock my S3 for running graphic intensive/slow loading games like Asphalt 7, etc.
So far for that purpose it's been amazing, the games literally open twice as fast. I've setup SetCPU for a variety of CPU changes, ie. higher speeds for graphic intensive games, lower speed for screen off while charging (ie. overnight) and it seems to be working great.
My questions are:
Can "overclocking" damange my device? Ie. I know that obviously overclocking shreds through battery life, but is playing a game at the top speed available on SetCPU (1512 Mhz) bad over a prolonged period?
Also, am I not reaping the full benefits of over/underclocking having a custom kernal installed?
Also...nother totally n00b one, if the S3 is capable of reaching the "overclocked" max speed, why doesn't it in the stock ROM? I just don't quite get that....is it because the battery life would be terrible and people would blame Samsung for it?
Never had a issue overclocking. And I've overclocked every phone I've owned beside the iPhone.
As far as how much better it will make your phone it depends. Depends on the rom too. I've noticed better benchmark results yet not always better real world results.
I use it more for the ability to underclock, and overclock when necessary.
Sent from my SGH-I747 using xda app-developers app
a little off but do you know of a way to measure the temperature of the phone (when you overclock/or even normally) ?
My phone does heat up sometimes
For over/underclocking there must be support for it built in kernel ! So if stock kernel doesn't support it you cannot probably change frequencies without changing kernel on stock Rom !
Also read the kernel's documentation - stable frequencies will be listed there - jumping back and forth these frequencies won't cause any troubles apart from the obvious battery drainage depending on your settings

Yes overclocking can damage your cpu from overheating, some even believe it may reduce the lifespan of you cpu.
If you are running 1512 max you are running stock mhz, that isn't overclocked. You cannot run a stock Sammy kernel and overclock it unless it's been recompile..to be overclocked.
I recommend ktoonsez kernel it can be overclocked to 2106mhz and underclocked to 96mhz. As well as undervolting support which is pretty much essential for overclocking because an undervolt will make your phone produce less heat by lowering the voltage your phone requires when running.
To answer your second question, yes you are not reaping any benefits without a custom kernel, this is evident.
To answer the last. The stock kernel is maxed at 1512 because that is the best mhz for the STOCK Sammy kernel performance and battery wise. Also its possible that overheating happened when they set the max at higher mhz during their tests.
Some good general knowledge if you decide to overclock, would be learning how to and what undervolting does for your phone. You can read up on that here:

Ktoonsez kernel thread: http://forum.xda-developers.com/showthread.php?p=28399829
Make sure you download the right one for your rom!
If after reading about undervolting and installing kernel and would like some safe undervolting and gov/scheduler settings let me know! You can also find many other settings here:

Sorry that kernal thread is a bit confusing.
Does that Kernal only exist for the stock carrier ROM and CM?
I'm using Triune II, if the kernal doesn't exist for that ROM then I take it I have to change ROM's?

No. Triune is a TW based ROM. Therefore, you need to download KToonsez TW kernel. Keep in mind there is a ICS TW kernel, and then there is a JB TW kernel.
There are other kernels out there. Faux123 has a good one. It is capable of OC to 1.8Ghz, I believe.

You may have a thin silicon layer around your chip that's causing it to overheat. Ever thought of undervolting?

It's actually very stable. Been on it for a month with no probs. Just a slight over heating that I'm curious about but now fixed.
The flickering of the screen when dimming/lighting is annoying though
