I'm seeing pretty good things for 1.3.2 so far. It's the only kernel that I've run on 100Mhz - 800Mhz (stock voltages) that didn't have a fairly noticeable amount of stutter to it.
Initially I was running it with lulzactive on the vr scheduler, but changed over to noop and noticed that its active usage seems to drop slower. vr scheduler was literally dropping battery percentage before my eyes at an alarming rate. The feeling I get from using this current setup is better than I've gotten from any other kernel so far. Active usage drain in my opinion is so much more important than standby battery drain, albeit harder to measure. To each his own I guess, but the way I see it, what's the point in being able to standby for a week if everytime you turn the screen on it feels like you're leaking battery fluid.
Great work Simone, I think I've found my first kernel that I'd actually like to stick to for a while!
Edit:
I think it's fair to say I'm a heavy user, so I'm pretty happy with these results.

Hello hawker!
Thanks for all your posts. They are always very helpful.
Following your guides, I now have CheckRom v4, Siyah kernel 2.6.11 and LP6 modem. I made all Voltage Control settings, etc. The system runs fine but I would like to try N.E.A.K 1.3.2 as I guess it can take more out of my battery.
Please, share with me the results of the comparison you made between Siyah and N.E.A.K.
So, please, let me know the steps I should follow to install it. Up to now, I've downloaded the .zip file and I will copy it to my phone internal SD.
What wipes, cleaning scripts should I use before flashing the new kernel and what about the configuration I've made with 2nd Core and Voltage control? May I leave them the same?
Many questions. I don't want to "brick" your mind
Thanks from Argentina,

NEAK 1.3.2 v Siyah 2.6.11 is a close call.
Both are very VERY good kernels and you will not go far wrong with either.
The reasons I am sticking with NEAK at the moment are :
1. I prefer the NEAK CWM Recovery to the Hyperdoid version of Siyah. I find the red text difficult to read.
2. I'm getting better battery life on NEAK. Typically I get approx 0.5% per hour overnight drain, whereas on Siyah, it is more like 0.8% - 1%
Download my kernel cleaning scripts from here
Flash the cleaning script (either will do, but GS2Blitzer is more suitable if you are changing kernels completely)
Then flash the NEAK zip file
As you are already on CheckROM/LP6 modem/Siyah you are obviously familiar with how to flash via CWM so I won't teach you how to suck eggs by explaining how to do this.
I would forget any voltage control settings initially, as what works for one kernel on one individual's handset may not behave as well on another kernel.
Once your running on NEAK defaults, I would then begin to consider Voltage Control tweaks.

Thanks again hawked! I flashed N.E.A.K 1.3.2 after flashing script GS2Wiper. I would really appreciate if you could help me now setting up lulzactive, voltage control and 2nd Core (this one if necessary).
CWM is also giving me an error message saying it needs CF-Root v5 or newer. Is it possible to fix this?
The only words I can say are "Thanks, thanks and thanks". Your posts are helping me a lot.

Forget lulzactive app and forget 2nd core
focus on VC settings. A start point is to knock off 50mV on each step and test.
generally I put 100 and 200 mHz to 850mv
also try setting GPU low lower to 100Mhz and 800mV. Put back to original settings if this causes you trouble.
I've having best results on neak with conservative/noop with sched_mc enabled (done so through the neak menu in CWM recovery)

To see if I understood correctly: You do both things. Setting conservative and sched_mc in recovery (I already did that) and you also lower the voltages starting from 50mV each (all of them). For instance: 1200Mhz to 1200mV.
GPU Low power rate to 100 and 800. No changes to High performance and Charging current which are at 750; 650 and 550 respectively..
In Menu General i/o scheduler is set at vr and lulzactive as governor
After that I save (init.d checked).
Is that OK?
To end: Are you using any kind of battery saver such as JC besides this settings or not recommend them at all? I'm not using any of those right now.
Thank you again!

generally speaking I will apply a basic undervolt set that i'm confident will work initially. You will get a feel for how much you can push certain kernels.
I will then try pushing it harder by u/v one step at a time by perhaps 25mv
I'll test this step for a while on general use, so play music, videos, browsing, etc.
Also during the test remember to leave the phone on idle several times to make sure it's waking up from deep sleep properly.
If all seems will with no freezes I'll save the settings for boot.
I always save vc settings as init.d script. This way I can keep a copy and restore it if I require at a later date.
Its also safer this way in case things go wrong as you can flash a vc zip to remove its settings. This only works on settings saved as init.d script, so you will always have this as your get out of jail card.

Rudedawg dumb question of the day
.... Running NEAK 1.3.2 , experiencing some weird phone lock ups but that happened on siyah also so considered my battery options.
Arnt i supposed to see more governors than this? Does NEAK not have conservative ? Never seen this Lionheart governor also. Something I need to add elsewhere?

Only on 1st bloody coffee... give me a break!
I'm loving this N.E.A.K. 1.3.2... its blooming gorgeous.
If I was forced to compare this to Siyah 2.6.11, I'd have to say that this baby has the edge for me in terms of performance and battery... which is saying something, as Siyah is pretty darn good.
