[Verizon Samsung Galaxy S 4] ATGkompressor:
Since I received so many inquires into how I chose to save a moderate volume of battery power via trial and error, I decided to write up a little "this is what has worked for me" post.

First off, like I said, "this is what has worked for me," so I'm not held accountable if you manage to kcuf up your phone...cool? Ok.

Second, I take no credit in the development, research, exploits and other such methods used to obtain the following masterpieces of Android Development: Kernel Auduitor's devs, [MENTION=4168602]klabit87[/MENTION] for his awesome work and support (as well as those who preceded his work), and [MENTION=4840281]stang5litre[/MENTION] for a brilliant ROM (v3) that allows such flexibility.

Now...keep in mind battery life greatly depends on what apps you have and frequent, location, sleep patterns...basically how you use your device. Ok, enough blabbering...

Once you have followed the instructions from http://xdaforums.com/showthread.php?t=3321587 to a tee you must first read and study how each governor/io is structured and why.

Here are the basic parameters I'm running:

*Version 1 Configuration

Governor = darkness

I/O = fiops

Multi-core Powersaving = Aggressive

MP Decision = off

TCP Congestion Algorithm = reno*

Entropy - Read = 1024

Write = 2048

Low Memory = Aggressive

And I pulled the VFS Cache Pressure down to 5 in Virtual Memory.

Here are the basic parameters I'm running:

*Version 2 Configuration

Governor = alucard

I/O (Internal) = fiops

(External) = vr

Multi-core Powersaving = Disabled

MP Decision = off

*Thermal = SoC Temperature Throttle*

TCP Congestion Algorithm = cubic

Entropy - Read = 256

Write = 1024

Low Memory = Medium

Return VFS Cache Pressure to its default value of 10 in Virtual Memory

In addition to all of that, I use Greenify, Recently, Coolify and various native settings (i.e. Auto-bright -3, screen timeout, no transition animations).

The Version 2 Configuration is a great, harmonically balanced tapestry of performance and energy conservation.

I have tested this particular set-up fairly extensively, with a little tweaking along the way. And I feel that this is the optimal configuration, given the parameters. You guys may wanna play a little bit with the Entropy, because I did so and am still playing with it just to see what kind of performance I can achieve.

Below are a few screenshots of my set up (Version 1 Config).

Screenshots for Version 2 Config http://xdaforums.com/showpost.php?p=66528774&postcount=15

Device: SCH-I545

ROM: stang5litre 5.0 Edition v3

Bootloader: NK4

System: OC1

Xposed: v65 _ Version3.0Alpha4

**NOTE: You WILL have to play around a bit to find out what works best for your style of use.

*EVERY DEVICE/EXPERIENCE METHOD WILL BE DIFFERENT!

***UPDATE: I have discovered that setting TCP Congestion Algorithm to reno has a *POSSIBLE* negative effect on battery life over a certain period of time (1 week to be approximate). I've specifically related this to streaming content on YouTube via background playback (Red or Xposed).

*Thermal* PLEASE READ! I did encounter and record abnormally high temperatures when this setting was set to Core Control.

Feel free to post info, screenshots or feedback that document your device's performance!
