Scott's CleanKernel v. IMO's leanKernel

IMO updated his TouchWiz kernel yesterday. Up until today I was using Scott's CleanKernel. Both are amazing kernels in my eyes. Both kernels are undervolted and overclocked. I had no issues with CleanKernel at all. I always seems to have bad battery life on the leanKernel until I flashed the updated .4 version this morning. Battery life seems much better compared to any leanKernel before the update. When running CleanKernel, I got a quadrant score of 4980. With leanKernel 0.4 I got 5160, both at stock 1.5GHz. I just want to see if others have noticed what I have between these two kernels.

You forgot that both are released in the Development section. A place where this thread does NOT belong...

A mod will move it in when they get a chance.
Just so you know in the future,
if your not a developer its always safe to open up new threads in the Q and A section. (At least that's my rule for myself.. it saves you from the "I'm having a bad day so I will take it out on this guy" post)

Now that this has been moved can we get back on topic? What is yalls experience with these two kernels?
Sent from my SCH-I535 using xda app-developers app

personally i like leankernal because of how light and simple it is. no unneccesary weight and battery life is great.

Clean kernel is closer to stock than imos kernel which is kinda good and bad. The more you modify the kernel the more chance you'll have of breaking something but you also have the posabilty of making it way better if done right and everything comes out ok.
I would expect clean kernel to be more stable, less battery efficient, and a little slower overall. Where imos kernel could vary drastically with each update due to more major things being edited or changed. Right now imos beta. 4 has pretty good battery life over stock and is stable.
Personally I try the more modified stuff first and if I don't feel it pays off I move to something more stable or closer to stock until an update is released or problem addressed. Just my. 02

Clean Kernel is under volt by default for a given frequency. That is why the battery life is better. If you are looking for both performance and battery life, you should over clock Clean Kernel frequency to 1.89 (default is 1.5) max and min should be 400 range. GPU in Clean Kernel is also over clocked. "stable" is the key word to differentiate between the two. I would think that Clean Kernel is the most stable kernel of all. For speed they should be the same, for bells and whistles, Lean kernel would be your choice. To sum up, Clean Kernel give you both world, stable, performance and battery life... unless you want something else beside those 3.

So you're a cleankernel guy? I definitely agree with you about this being all three things. So as far as the GPU being overclocked, why does lean kernel .4 perform better in games

Like I have mentioned, if you aiming for gaming performance then you better to use lean, but then your battery life wouldn't be too good. Most of people just want a fast stable phone and a good battery life for daily use, then Clean will be a better choice. The reason it's stable because no tweaks to it except for OC/UV. Have you tried to play game with Clean over clocked to 1.89?

Actually I never thought of overclocking and playing the game until now. I guess Im just used to being at stock. But I will give it a try and see how that works. But what your saying definitely makes sense and should clear some things up. Performace + battery life = cleankernel. PERFORMANCE + PERFORMANCE = leankernel. Although the battery life on leankernel has dramatically been improved.

Haha.. you got it...almost.. Performance+battery life+stable=Clean. Super perfornance -less battery life - 10% stable=Lean kernel. Good luck bro.

ok I just setup an app profile in setcpu. so now everytime im in my game, its overclocked. When im using it normally, its at stock speed. With the screen off, its at min 190 and max 452. so far so good!

.5 is up now with more fixes.

Thanks for the heads up! More battery drain fixes. Although it says in order to revert back to stock we have to flash a ROM with a kernel. Would a nan backup work? Anyone tests the kernel yet

Best kernel for saving battery on 7.0?

I am on cm 10.1 and the battery isn't much different from stock. Also, the tab gets hotter than it did on stock. Any kernel that keeps the device cool and saves battery? I am willing to change ROMs if its CM's fault, but the ROM you suggest should be waaay better to convince me to change ROMs.

Also you can try ketut kernel...
And about other Roms cm10.1 is best one after stock 4.1.2(debloated)
And device getting hot is normal.

Bike Race runs fine at 300-600MHz. It still heats up quite a bit though.

[Q]Overclocking voltages.

I will get straight to the point.
I'm currently (and always have been) a happy owner of a nexus S, I have used many ROMs and different kernels, currently I'm using Carbon+Marmite 8.7 bigmem and I'm very fond of taking my phone to the max, however I'm facing a few issues. I have to push ARM voltage and int voltage very high in order to archive any sense of "stability" usually near max. Would this by any chances damage my phone? The way I see it, pushing it too high would only make it hotter but the silicon can survive at very high temperature and the board can too, at least higher than when the CPU can heat up to.
Thanks in advance.
PS: My Antutu scores and configurations
Sent from my Nexus S "Firebird" using xda app-developers app

Hi mate,
There isn't a risk that your phone will burn or some internals will melt but if you're giving your processor hard times it could potentially damage it because you wear it down in the long run.
As well of course of the battery price that you need to "pay".
Cheers.

If you want to push your phone, Devil is the way to go.. It is more stable at the higher frequencies and coupled with an app like Devil Tools it can be live overclocked (108%) to a stable 1514mhz.. Marmite seems to have reboots when pushed on any OC..

Thanks for the replies guys, both marmite and helly doesn't like my phone much, helly would reboot every time I try to overclock, the only "stable" kernel for me is matr1x which doesnt work well with Carbon for some reason.

Increase the voltage by 25 on 1200 and 1300 and 50 for 1400 on Devil and it should make it more stable..

But I've noticed when powered off and charging, the battery icon graphic on the screen is all jacked up with the included kernel in Liquidsmooth. This BMS kernel has resolved that issue. Maybe its related to that somehow? I have no idea. Lol.

It's a little weird to explain until you actively test it. In your rom, there should be a Settings/Advanced Options/Phone (or Advanced Settings). Go there and you can adjust the display temperature to be warmer (more reddish) or cooler (more bluish). Make sure to turn the display off each time you change the display temperature for it to take effect.

You might be confusing the terminology. Stock max cpu speed is 1512 mhz but the voltage would be about 1200mv at that clock. 1566 would be in reference to the clock speed.

For some it looks like as its a placebo affect, but when you launch CPU intensive apps such as Photoshop touch and other cpu intensive apps you start to see the affect.

Had some issues with the Facebook app on ART (seems to be fixed now), but otherwise, it's been flawless. No issues.
However, I will be honest and say that the speed improvements have only been marginal for me.

I can see a difference between ART and dalvik. Apps are snappier and battery life is slightly better. It's very smooth. The only thing on the negative side is some apps will not work (very few) and boot time takes a couple of seconds longer. Other than that, it's great!

First thing I do after I flash a new ROM is enable ART Pretty much the best thing to happen for performance on Android since Project Butter on Jellybean. It's quite stable, and most of the big apps that used to be buggy with ART have been fixed. After the initial boot after switching to ART (which takes a few minutes, depending on the number of apps you have installed), boot time is quicker, and everything is just buttery smooth. If you thought that the phone couldn't get faster, you're wrong. It does something to the scrolling especially that just makes everything fly.

To be honest, you won't see a difference. Split seconds are not noticeable to us. How snappy do you need your phone to be? ART or Dalvik, you will see no lag.
