WARNING: Use this settings at your own risk. I am not responsible for what will happen to your phone.

So, Siyah Kernel 4.1.4 has been released, and since 4.1.1 and its new features I have struggled for obtaining maximum battery life without loosing smoothness.
I tested these settings on 5 phones (Galaxy S2 GT-I9100): mine and my friends' ones, and we all got the same (more or less) results: it's awesome!
Screen usage can get up to 7 hours. I did these tests with mobile data on for all phone usage, and not in deep sleep. When I was at home I switched to Wi-fi.
My ROM is AOKP M6 (ICS 4.0.4), other tests were made on Resurrection remix JB, stock XWLPF (ics), CM9 stable (screen usage: about 6 hours, no more), and AOKP JB (latest).

Extweaks settings:

CPU:
GENTLE FAIR SLEEPERS: ON
CPU HOTPLUG: (default)
CFS TWEAKS: Linux kernel defaults
CPU IDLE MODE: AFTR+LPA
SMOOTH SCALING LEVEL: 800 mHz
MAX CPU LOCK: Dual core mode
CPU UNDERVOLTING: - 50mV (if you get freezes, set -25mV)
CPU STEP COUNT: 16 (all available)
GOVERNOR: pegasusq
MAX FREQ: 1200 MHz
MIN FREQ: 200 MHz

GPU:
MALI TOUCH BOOST LEVEL: Step 2/Step 3
GPU STEP 1: 44 MHz
GPU STEP 2: 66 MHz
GPU STEP 3: 100 MHz
GPU STEP 4: 200 MHz
GPU VOLTAGE LEVEL 1, 2 AND 3: 800 mV
GPU VOLTAGE LEVEL 4: 950 mV

THRESHOLDS: default values

AUDIO:
HEADPHONE AMPLIFIER: 0 (set this value as you want and as you ears can stand it, it doesn't affect battery life unless you listen to music)

SCREEN:
TOUCHMOVE SENSITIVITY: 3 pixel
ALL OTHER SETTINGS: default values
mDNIe negative toggle: off

BLN:
BLN: off
NOTIFICATION TIMEOUT: never timeout
BLN EFFECT: set what you want, cause BLN is disabled
LED TIMEOUT: use ROM defaults
LED FADEOUT: on
LEDS ON WITH TOUCH: off
LED VOLTAGE LEVEL: 2700 mV (2750/2800 mV if led lights are dim)

MISC:
ANDROID LOGGER: off
DEFAULT I/O SCHEDULER: cfq/noop
ALL OTHER SETTINGS: default values

I think they are not too aggressive values, but if you get freezes, I recommend you reset your extweaks settings via CWM recovery and then use less aggressive ones.

In the attached screenshots, battery stats analysis starts from 91% since I had to restart my phone, and when it was at 10% I plugged the USB cable in to transfer a .zip file in my SD card, but I don't think that this 15-second charge affected my test (I'm sure it didn't!).
Phone usage was high today, I used Tapatalk, created a new UCCW skin, did some long phone calls, Facebook, messaging, e-mail checking, and other stuff I don't remember since the battery stats don't even report them (lol).

Notice that this is an extreme test. 7 hours of screen usage is not a myth, reality instead, but you cannot get them with the so called 'everyday usage'.

Screenshots of test made on my usual phone usage will come soon

I don't think these settings are good for performance... I have used even higher settings and there was lagg in some cases. But that was all on my phone :P

This seems largely similar to my MagicConfig thread.

7 hrs screen time with 1200mhz max frequency and stock battery.. how much more if it's set on 800mhz.. 8-9 hours probably on stock batt? O.o

you could have atleast included what you were doing in those 7 hours screen time like browsing, texting, facebook, etc, also the brightness of the screen, battery chart..
