[AT&T Samsung Galaxy Note I717] Anthony820:
Speed & Battery Improvement Guide - as if it's needed.. :)

So, since I take for granted things I think are common knowledge, I figured I would create a quick guide to some of the features of the ROM that will increase speed/battery. Or some things that you can do with free tools which should have relatively big impacts on one of the two aspects.

1. Greenify

Greenify is a tool which does something similar to TItaniumBackup's freeze. Except as soon as you start the app, it's unfrozen. So it's still available at all times, but it won't run in the background, and likewise, won't start unnoticed services. Greenify should have a major impact on increasing your overall speed AND battery life. The only caveat is things you hibernate will NOT receive notifications. Since I only care about email and SMS, I freeze nearly anything and everything. Simply start greenify, click the "+" button, and tap away. Anything you don't care about notifications of, you may add. If you find you added something you DO want to have running in the background, simply go back in and remove it from the list. Easy Peasy.

2. Underclock

If you don't game, you shouldn't notice any responsiveness loss by underclocking down into the 1100 range. If you want something free, quick, and easy to use, I recommend IncrediControl -- check the play store. Simply drag your slider down to the 1100 range and give it a shot. I personally run at 1188 and don't notice any sadness in my phone.

3. Animation Speeds

I like the fancy animations, but they are a little long winded. If you want to increase the perceived speed of the ROM, go into Settings, Developer Settings, and change both sets of Animations down to 0.5x. You'll still see the animations, but they will be much zippier. At first I thought they were too quick, but after some use, you will see that it isn't too fast to still enjoy them.

4. ODEX Everything

Now, I'm not going to get into a class on Deodex vs Odex. But I will say, for the average user, especially of an AOSP rom, you don't need things deodexed. A deodexed ROM is useful because it makes customizing things easier. Something needed in Samsung ROMs. But unless you're a dev, you're probably not decompiling APKs and editing smalis and XML files. If you don't know what either is, or have never decompiled an APK in your life, you do NOT need this ROM deodexed. Odexing a rom -- although arguably -- increases speed, battery life, and storage space in /data. Thanks to MatrixDJ96 for this script.

1. Download attached file.

2. Flash it using TWRP or whatever.

3. Reboot, run Terminal Emulator

In TE, type

su

hit enter, type

dexo -all

hit enter, wait

When it's completed, reboot. Rebooting will take slightly longer. Upon reboot, run terminal emulator again, run su again, but this time you want to run:

dexo -dat

That will odex all your installed apps as well. This will take longer, as will the reboot. Some users say it can take 15+ minutes. All depends on the amount of crap you have installed. Just wait it out. Once your phone reboots, you will see more space in /data, and even if it's placebo, more speed and battery life.

The only thing of those "tricks" that could effect performance is underclocking. The rest will all increase speed and battery life. Pinky swear.

Happy Friday, people.
