Not to get into a pissing match but Vlad83 answered correctly and properly and for that, a thank you is coming your way.

Anyways, Vlad83, was answering in a general way and TheSeanTeam was answering regarding the latest version. I do know their were changes and fixes made which were posted by WH and I was looking for a more general reply.

But regardless thank you to all.
[T-Mobile Samsung Galaxy S II SGH-T989] Vlad83:
Seriously guy, I was providing a broad explanation that's not that difficult to crack. My intention is to help, yours is clearly to troll...

No trolling intended. Just added to your theoretical answer.

[T-Mobile Samsung Galaxy S II SGH-T989] JaylanPHNX:
The most specific answer to the question is that the fix for the touch screen lockup issue is in his kernel. Flashing this one well bring back that issue. But I never had it that bad, so not a problem for me. YMMV

Flashed this on CM9 Nightly builds 7.4.12 & 7.5.12 for the T989, it killed the function to charge phone battery when device is shutdown/off. This was always a issue in CM9 that the more recent builds seemed to fix. Flashing this kernel killed that fix, but yes I did get better battery life and performance using lion heart cpu governing with this particular kernel.

But I would hate to not be able to boot my phone up if the battery dies one day. For now I'm back to the default kernel built into CM9 Nightlies. Hopefully my battery life will improve as I recondition the battery and let the ROM "sit" on my phone. Would of loved to use this kernel though.

Hey guys, i LOVE this kernel, got a 39xx quadrant with this bad boy! :) However, i am not sure if its something i did, something wrong with my data, or if its SetCPU or if its ondemand governor issue or what it is, hence why im posting. However....

When i have ondemand set as current governor in SetCPU when i turn my screen off, it doesnt turn back on and it reboots. I havent had this issue with my ROMs stock kernel so i think it may be kernel related. But if i change governor in SetCPU and then change back to ondemand, it wont reboot upon screen off. But then after awhile of using it, it will. So im not sure whats goin on, plus there isnt anything showing up in logcat or dmesg. Thanks all for your fantastic work! BTW EUGENE did you get my PM? Id like your source code so i can tweak the kernel some more since its update is old ;) but i still love it!

Eugene. Is it possible that this kernel can cause random reboots if my rom is the paranoid android rom?? Things were great for almost a week and starting about days ago I get these random reboots. Not bootloops but quick reboots. Never happened before. Not blaming your kernel, just trying to get your educated guest. Thanks man
[T-Mobile Samsung Galaxy S II SGH-T989] playya:
Not sure if I got lucky or this will work for you but when I used to get random reboots I would reboot into recovery wipe cache and fix permissions. Doing this 95% of the time helped me out.
[T-Mobile Samsung Galaxy S II SGH-T989] suaverc118:

Sorry for not being specific. This is for the TW kernel V4

i had the same issue when changing from ondemand governor to conservative during screen off state. I think the governors need some fine tuning. I did however switch to antutu's cpu master from the market and experience less reoots. Oh speaking of, my phone wouldnt go into SOD, it would just screen off then reboot.
[T-Mobile Samsung Galaxy S II SGH-T989] Chochiwpg:
Hey Eugene, I have a request. Would you be able to release your current TW Kernel with the rotation fix for us Telus users? I really want to run your Kernel but my rotation is all out of whack. If you can't it's cool. Thanks for all the hard work you do. Peace.

Flashed this to see difference between Synergy. So far seems smoother, and battery seems longer. Stress testing tonight, then running my heavy games I play all the time. So far using SetCPU, with Lionheart Gov, runs amazingly. Not really into UV'ing...think it does stock? If it is, then ok, if not...not changing.

I have been on this Kernel for over a month now and Lionheart (Default) has worked the best for me. I am overclocked to 1.51GHz and UnderVolted -50mV and battery life as well as performance is fine. I use System Tuner. It is the best in my opinion. ;)

EDIT: 1: In System Tuner: Go into Boot Settings & Re-Apply SD Tweak to init.d script. & 2: Re-apply CPU Settings to init.d script. Reboot and Enjoy.
[T-Mobile Samsung Galaxy S II SGH-T989] TerrorCandii:
Day 3, kernel seems to get smoother with use. Definitely loving this and the Lionheart gov. Makes me disappointed with Synergy, since I used it for so long. Changed because it seemed to get slower with age. I decided on this one because I've used Eugene's work before, and it's amazing thus far.

Too low causes errors and increases cycles negating any benefits. Don't ask what too low is because every processor is unique even if it's the same model. To be honest UVing is a gimmick, there have been studies done and it yielded something like 2% more battery life under the best conditions...

Here is the thread.... Everyone should read it: http://xdaforums.com/showthread.php?t=1478406

Summary of Results

#1 - With screen on, if the processor is Idle, 100MHz saves the most power.

#2 - Regardless of your choice of governor, even with extreme undervolting, you are not going to be able to increase your battery life by more than 2%. (Click here for explanation.)

For the instability introduced by UV, it seems a 2% increase in battery life isn't really worth it! REMEMBER rebooting uses so much power, a single one would more than undo any savings made by UV.

#3 - The most power saving governor is Ondemand. If you need a high performance governor, use smartassV2, which offers some battery savings.

#4 - This is one point that everyone ought to know, but I'm including because many people seem to believe in myths: if the screen is off, and the CPU is not active, neither deep idle nor UV will have any impact on battery life.

#5 - The matr1x kernel by mathkid95 mainly saves power through UV of the INT voltages. You may need to raise these if you have freezes/reboots with your phone (in addition to raising the ARM voltages). I found that a maximum of 1 mA can be saved through INT UV, regardless of whether the CPU becomes idle (or with screen off in deep idle), so this is a constant saving. However, it is a very small saving, and doesn't apply if the phone is asleep. Remember, reboots cost more juice than UV can ever save.

#6 - If you have an amoled display, black saves a great deal of power. After that, red. If you have a black and red theme, this is saving you power!

#7 - If you are determined to UV, I found that my phone would become unstable with UV settings that were fine when the battery was fully charged. So check what UV your phone can handle when your battery is nearly empty. Again I say: Because of the high likelyhood and massive battery drain that comes with a reboot, I highly recommend you DO NOT USE EXCESSIVE UV. Also remember, even with extreme UV, you will not increase battery life more than 2%

#8 - I found that with bluetooth or GPS preventing the TOP=OFF state, there was no additional power saving from Deep Idle, i.e. the TOP=ON state does not save power.

#9 - Kernels with the 65 fps hack will cause the screen to drain about 10% more power compared to the usual 56 fps.

#10 - Conservative does not save power! For further details and exceptions, refer to my new thread: here.

#11 - This is just general advice: if you are having very poor battery life, have you tried turning auto brightness off? And if you've got no reception, you might as well be in airplane mode, because searching for reception also eats battery.

#12 - If your phone can't handle OC (or UV for that matter) it's because components in general are built to cost, which means factoring in tolerances, and every chip is made as cheaply as possible within the specified tolerances. Outside of those tolerances, whether your chip can cope or not is unfortunately down to the whether you got lucky with the individual device that dropped off the manufacturing line.

Thank you for the great link. This answered my questions far beyond and above. :good:
[T-Mobile Samsung Galaxy S II SGH-T989] AznDud333:
there is no downside to the hardware when it comes to undervolting, what happens is that lower voltages is delivered to your cpu(or SOC, when it comes to phones like these) which results in less power consumed and less heat emitted(which is actually good for the chip), battery won't suffer either..

there is one downside tho..your system might crash, anyone who overclocks their cpu knows insufficient voltage= instable system, so don't over uv..
