    Flashed 3/23 this morning and I think hashcode must be close to a fix for the 4g. It picked up faster than it ever has before and has been perfectly stable since with almost full bars the whole time. ( I live in a big city) I have a few hours to waste so I"ll play around with this build for a while and report back with bugs.

    So 45 minutes of heavy use of 4g it only dropped once but restored itself without me having to toggle wifi or gsm. I would say any one worried about data could probably rest easy with 3/23. The camera is in the same place so only the camera works panaroma and video don't work.

    I am not doing any audio or video decoding though. Would the lack of hardware decoding support affect web browsing and idling, as in my case? I guess if something such as scrolling in the GUI is hammering the CPU, that would make sense.

    Are there any GUI related tweaks to lower the priority of the screen rendering to decrease CPU/battery use? I wouldn't mind trading a smooth GUI for better battery life. Most of the time I am viewing static content anyways.

    Juice defender only helps if you Don't use your phone often. Which kinda defeats the purpose of the smartphone being a smartphone. Reason being - depending on your Juice Defender settings it will often turn off radios and WiFi, resulting in each time you want to use them it has to connect to them. Which requires sending signals back and forth each time, resulting in more power consumption then just leaving them go.
    tl;dr, the less you use your phone, the more Juice Defender helps. The more you use your phone, the more Juice Defender slows you down and kills your battery quicker.

    Exactly, JuiceDefender only works by switching off the 3G/4GLTE radios when the screen is off. I was looking for ways to minimize the computations used by the OS, assuming that the high "Android OS" usage is caused by GUI rendering that is prettier than it really needs to be. I already have "Window animation scale" and "Transition animation scale" both set to "off" under "Developer Options". Just wondering if there are any further tweaks that may help.

    I have both of those set to off too. I'm sure most people prefer the animations, I'm just the minimilistic type. I wonder if turning those off actually has a opposite affect on battery, rather then saving slightly more haha. Idk, people say this ROM gives great battery life, I just get about a wake-to-bed use out of it on 4G. It's gotta be something I'm doing, I disable almost everything that's not necessary and uninstalled Facebook, still showing 67% used by Android OS. If other people saw their Android OS using a lot, I think they'd post and wonder about it, leaving me to believe it is something that just we are doing. Only things syncing for me are of course Gmail and Beautiful Widgets for weather.

    Hmm it would be interesting if we were the only ones with this AndroidOS problem. Are there any ways besides BetterBatteryStats to peek inside what the AndroidOS process is doing that's causing all this usage? As for me, the only things I have syncing are Gmail, Touchdown (MS Exchange client), and the built in News & Weather widget (set to only show weather). Looking at the battery history details graph, the vast majority of the times that the phone is awake coincide with times that the screen is on. So to me, that does not suggest anything too strange happening with the phone being woken up for syncing.

    It could be possible that there is a bug in the built in battery stats... if anyone could recommend an alternative battery stats app other than Batter Battery Stats (which I already have), I will install and post some new findings.

    Regarding Facebook, I've been using an open source app called "Tinfoil for Facebook". It's just a wrapper for the Android web browser and loads Facebook, so it's basically sandboxed from your actual browser's cookies/state/history and that sort of thing. It works pretty well and I have not seen any problems related to the app sticking around killing the battery, as some others have complained about in the actual FB app for Android.
