Guys, i am not expert in this. but as i was facing battery issues too with miui, i came with some tweaks which gave me good battery result....so helping people about battery issues.
So please Don't blame me,if you dont get good results......your settings are crap and all,because i am just helping people.
and i am sure,if you follows all the steps,it will help you also. because i got 250+(pm) positive feedback about this tweaks,so posting here.
SCROLL DOWN FOR CM9
here are some tweaks :-
basics :-
Turn off Bluetooth,wi-fi,3g data connection,GPS when they dont need.....if you dont wanna do it manually,Use Juice Defender(LINK) app. But i will recommend to do it manually,as that app will also consumes some battery

so out of all kernels you would recommend dk 2.4.3. for best battery life... have you compared your findings with void. echo and siyah? siyah was good for battery life before matched with wajkiui but then after updated to latest kernel my battery is dying... void.echo is worse... pls help.. battery life is my biggest problem! will your settings differ for different batteries i currently have a 2000amh.. and switch between the original when one dies... at this rate il need a third battery =_=

Ok that sorts that out. Thanks again. And yes. So far so good!
I don't know if it is normal for my CPU speed to be so low, I know that it lowers to save battery but it is always so low and I can see the effects it has. Anyone else get something like this. (quadrant standard edition)
yes it's underclocking to use lower battery when not needed ,it's perfectly normal.
don't worry , it'll fire full throttle (1400 MHZ) when you run a game or something demanding.
Use cpuspy with it you can check the times that CPU spends on each frequency.

Thanks. I was a bit worried because on other devices I tested the processor was always at maximum.

Did you at least readed it?
It says Minimum 200Mhz and Max 1400Mhz.
Its how note works. From 200Mhz to 1400Mhz. It scales the CPU speed from 200 to 1400Mhz when you need power.
It also can disable one of the two cores (CPU1 always) to save battery.
It also says that on the galaxy s 2 but that did not go below 1200MHz when i tested it so I was not sure.

Something was wrong with your GS2.
It says 500MHz because that's the current frequency it used when you took that screenshot. If it had said 1400MHz, then it would mean that it used all the power to take a screenshot, which wouldn't be normal.
The CPU isn't working at 1.4GHz 24/7. If it had done that, your battery would have lasted for 1 hour. It uses as much as it needs to, and if an app doesn't require much power, it won't use much power. Simple.

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

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..

Try the GetRIL app, it should be able to find the RIL for you.
But if I understand correctly, KH3 is a Modem from the GB firmwares, and you're running and ICS Firmware, the RIL is part of the Firmware and I don't think you can install a GB RIL on ICS... but try the app.

I configured my phone with your settings and it's running nice.
I can't really feel a difference in "smoothness" and it's the first time I change GPU frequencies and UV... but I still can't really tell a difference... what should I expect from changing GPU params, other than battery life?
buddy i cant find Siyah Kernel 4.1.1+ do you have any dwonlad that.
Hi, i have this problem. I have cm 10.2 and setVsel for control the cpu frequency speed. I set 300 17v, 600 45v, 1000 54v and 1200 66v.
My problem is that in the first 2 minutes all work ok but after 2 minute the cpu works only at max 1000mhz of speed. I can see it because i have installed spy cpu and for example now it marks:
1000 10%
600 67%
300 8%
Deep sleep 13% (it sleep a bit)
The missing 2% is the first 2 minute that the cpu works at 1200mhz in the first 2 minute.:silly:
Someone can explain me why?
Other two question, why cpu spy don't marks other frequencies over: deep sleep, 300, 600, 800, 1000?? And downvolt the cpu really extend the battery life??? because i don't see difference (max 1 hour of extra life)

You can change that behavior in Aero Control. Change hispeed_freq and input_boost_freq to 1200000. Undervolting doesn't extend battery life by a huge amount.

I have the same PVS CPU than you with 0,9 Volt at 384Mhz and 1,05 Volt at 1,5GHz.
I could undervolt 50mV accross the board; undervolt the lowest frequenz (384Mhz) to 0,73 Volt and overclock the CPU to 2,0Ghz max.
Im running Cyanogenmod with Glitch Kernel and use Trickster Mod for OC and CPU UV.
With Glitch Kernel I can even undervolt the GPU 100mv accross the board with an increased max GPU of 450Mhz.
(More is possible, but I nearly dont play games with my tablet)
With this I get about 8 hours of SOD time with Surfing.
When I'm on a long business trip and use my N7 for (Kindle and pdf) offline book reading I reach something like 13-15hours SOD time.

When I'm on a long business trip and use my N7 for (Kindle and pdf) offline book reading I reach something like 13-15hours SOD time.

I know a bit how i can get to know my cpu's pvs stepping, but since you have the same as me, what is it exactly? And is it considered a fast, normal or slow binned cpu?

mine are way lower and im pretty stable, no crashes but i dont' play games
im on ElementalX oc to 1.728ghz
at 38400 >>> im at 77500
at 702000..... 85000
at 102600.......90000
at172800 .... 102500
Whats the best way to test stability? Ive got this app https://play.google.com/store/apps/details?id=com.into.stability but i dont seem to get any wiser... Anyone know what i should do?

yup, run that for like 30mins on classic test, should be fine if it doesn't crash

I did that, but with voltages that are stable there, antutu crashes. And with voltages that are antutu stable, my device crashes randomly. I can run the scaling test with very low voltages across the board for more than an hour and it doesnt crash.
With other apps it just crashes.
This is an experimental undervolt that rarely crashes when switching apps:
I dont know which clock speed and its corresponsing voltage is unstable because the clock speed ranges from 384 to 1512 mhz and i dont have a crash log.
So I added 12.5 mV across the board, and this hasnt crashed so far!
But, being the perfectionist that I am, I want the Ultimate Undervolt. Is there a way to see what frequency you are running when it crashes?

I achieve stable 700mV at 1026MHz...
30mins stress run on "stability test" app and on stress run on "setCpu"
At 1134MHz the tablet freezes for the first time when I switch to 7875mV
Isn't it weird??
I dont think the stability test app is working. I could undervolt 1512 mhz to 900mV and have it run stable, but everyday use stable is with 987.5mV

I have the same PVS CPU than you with 0,9 Volt at 384Mhz and 1,05 Volt at 1,5GHz.
I could undervolt 50mV accross the board; undervolt the lowest frequenz (384Mhz) to 0,73 Volt and overclock the CPU to 2,0Ghz max.
Im running Cyanogenmod with Glitch Kernel and use Trickster Mod for OC and CPU UV.
With Glitch Kernel I can even undervolt the GPU 100mv accross the board with an increased max GPU of 450Mhz.

Will you post your voltage table?
What are the Kernel setup settings that you choose and have you ever OCed to 2.2 and still get good undervolting?
