My Setup:
Cubic
SIO
Read Ahead Buffer: 896 (The results for RAB will vary so experiment and find one that works best for you if mine do not yield preferred results.)
Interactive (hispeed_freq - 810000 in "Governor Control")
Min: 180mhz
Max: 1060mhz (1350mhz if you want a little more power at minimal sacrifice to battery, I am trying this out currently)
Max Screen Off: 350mhz (this is to avoid lagging/stuttering of music playback when screen is not on)
Min Screen On: 180mhz
WiFi High Performance: Off
Force Fast Charge: Off
Multicore Power Savings: 2
High Performance Sound: Off
Headphone Volume Boost: 1
Dynamic FSYNC: On
Tempature Limit: 80
GPU (If Available): 384mhz
GPU Governor (If Available): OnDemand
ZRAM: Off
Smartreflex: All On (MPU undervolted by 50 across the board) [with any undervolting there is a risk of freezing and/or SOD's, not all devices play nice with lower voltages so if you find that you are encountering issues just return to stock]
Core Min Calibrated Voltage: 750
IVA Min Calibrated Voltage: 750
MPU Min Calibrated Voltage: 750
I have, as usual, no lag, no freezing, great battery life and excellent performance with these settings
Also, my ram sits at between 270mb and 196mb free (unless I am using a heavy resource application or game, in which case it goes right back up after I exit the app/game), I have 126 apps installed.
My battery stats are as so, on low usage I get about 21hrs to 24.5hrs of standby (this can be much much higher depending on how the AK Kernel you are using reacts to your device) and 1.5hrs to 2hrs of on-screen time. On normal use I get about 15hrs to 17hrs of standby and about 2.5hrs to 3.5hrs of on-screen time. On heavy usage (which is only occasional) I get about 11hrs to 13hrs of standby and about 3.5hrs to 4.5hrs of on-screen time. Take into consideration, these battery stats are from a Toro Galaxy Nexus, this means those of you on a Maguro (GSM) model will probably get much better battery life than even this by using my settings.
My Colors:
Content Adaptive Brightness: On
Contrast: -5
Gamma Adjustment: 5
Gamma Offset Red: -5
Gamma Offset Green: -3
Gamma Offset Blue: 7
Color Multiplier Red: 260
Color Multiplier Green: 276
Color Multiplier Blue: 340
Regular Brightness Settings: Autobrightness is off and I have it manually set to 50%
If anyone has issues when the Green Gamma Offset is a negative number boost all Gamma Offset Colors up by 3 to make Red -2, Green 0 and Blue 10, then drop Contrast down to -8 rather than -5, this should give you almost the same result.
