Default Nephilim's Custom Kernel Settings


**These settings are meant for 4.2.1, 4.2.2, 4.3 and 4.4 kernels that I specify, the tweaks to certain areas however should work on more than just the kernels I include in this thread.**





[SIZE="4"]
Hey guys, as most of you from the AK Kernel thread may know (or now the DirtyV Kernel thread) and a few others that checked my signature links, I take great pride in customizing the best possible kernel settings for excellent performance and great battery, Since we've moved on from Android 4.2.x based roms and Stefano (AK) has since moved to the Nexus 4 I have been trying out other kernels, this means new settings to tweak and improve.

This Thread is dedicated to the custom kernel settings I use with some of my favorite kernels, I will still include my AK Kernel 4.2.1/4.2.2 settings but in addition I will be adding some new settings for a few kernels I think are quite impressive. Feel free to ask any questions you like, take from my settings what you like and answer anyone elses questions that you may know the answer to. I want this thread to be a community of help and not just from me. I do not expect you all to use my custom settings exactly, if you want to experiment feel free to, these are just a base to start with if you are not familiar with tweaking kernels and for those that are and enjoy my settings/colors, feel free to use them as they are.

The 4.4.x kernel settings will be occasionally updated if and when I feel there are improvements worthy of making so keep an eye on the thread for information on changes that may have been made to the OP.

I have no lag, no freezing, good battery life and excellent performance with these settings

Also, my ram sits at between 234mb and 145mb free on AK, ASKP and Golden kernels and between 355mb and 270mb free on Mpokang, DirtyV and Tiny kernels due the BIGMEM on Mpokang and DirtyV and ASRAM on Tiny. I have 128 apps installed.

My battery stats are as so, on low usage I get about 21hrs to 23hrs of standby and 1.5hrs to 2hrs of on-screen time. On normal use I get about 15hrs to 17hrs of standby and about 2hrs to 3hrs of on-screen time. On heavy usage (which is only occasional) I get about 11hrs to 13hrs of standby and about 3hrs to 4hrs 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.


Section 3.

Minfree Settings:
(Be advised, you must have the Donation version of Trickster Mod in order to add minfree settings)
 

Forground App: 10
Visible App: 20
Secondary Server: 100
Hidden App: 120
Content Provider: 95
Empty App: 195

These minfrees have been tested on DirtyV Kernels and Mpokang Kernels but should work just as well on all others. I've personally noticed an increase of 500+ points on AnTuTu as well as noticeable improvements on performance in everyday usage of my device.


Section 4.

Color Settings:
 

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.


My color settings work with any custom kernel, I feel that they have a remarkably crisp and vibrant tone to them, feel free to use them and tweak them as you see fit.

As always, if you have found this thread helpful please tap the "THANKS" button.

Good question, actually it is not an issue, especially since I set my brightness to 50%, even if you had it at 100% it would not affect it though, I've been using these color settings since I got my Galaxy Nexus and I've had no problems whatsoever with my screen.

Look at it this way, you do not see issues with LCD television screens for at least 3 to 4 years after you get them the thing about our devices is that we will most likely have upgraded before any of these settings could possibly affect them if they even do.

If another user's experience is useful, I used multipliers even higher than Nephilim and the only impact was a bright screen with vibrant colors. I used lux auto brightness so at time my screen would be at 100% brightness.

Glad to see my thread is being noticed, I hope to turn it into what the AK thread was but with helpful tips for multiple kernels rather than just one.
