    So you are up and running I take it. I've had issues similar to what you had because I had flashed the wrong kernel version so you are not alone

    I believe you go into terminal emulator type ffc and hit enter or whatever and it will fast charge. This only works when USB charging though

    You can go to performance options in settings and tweak from there I recommend sio scheduler and interactive governor. From my experience under clocking didn't do a ton its really good on its own. If you under clock I wouldn't go below 1350mhz. Honestly if my on screen time wasnt all from watching YouTube is get 20 or more hours out of the battery

    Didn't work.....or didn't show to have done anything. No biggie, just thought it would be a cool thing to do

    First type "su"

    Then type "/sbin/ffc"

    I'm a noob but found this on xda and it worked.

    On demand should yield better battery life than interactive. Conservative should do better than either of those.
    Interactive is too quick to jump up to the max allowed frequency. Ondemand is a little more lax and allows the CPU to sit at lower speeds while slowly ramping up to higher ones as needed. Then conservative is even slower ramping up.

    Interactive will give the most fluid performance as the CPU spends a lot more time at max frequency. On demand is generally a good balance of speed and battery life. Conservative will generally feel a little sluggish as the CPU ramps up slowest of the tree governors.

    I've been running different kernels for awhile and I have to disagree. It sounds right on paper but if I switch to an on demand governor the CPU likes to throttle up and sit at highest frequency based on touch whereas interactive will throttle down a bit. I ran CPU spy for awhile to find this out. The difference in battery life isn't even that much different between the two to not use interactive.
