    What are your settings to grab the best battery life out of cm7? I have Quick Clock so if you want to share clack speeds and vsel feel free.

    Is there anything else I can do other then juice defender?

    I just use setCPU to have the clock speed at its lowest when the screen is off. its set like this:
    screen off
    max: 300
    min: 300
    cpu mode[or whatever its called] performance.

    I'm on nightly build 29 and yesterday I had 17 hours with 51mins of display time, a few minutes of GPS use to find some directions, and the battery was at 50% I think.
    I know that wasn't the most heavy usage. Between just getting a Tablet and having been busy all day I didn't do much on my phone like normal.

    I'm going through testing with quickclock to see how low of a vsel I can get at the stock speeds. Right now I'm at
    1000 @ 47vsel
    800 @ 40vsel
    600 @ 30vsel
    300 @ 15vsel

    All except 1000MHz are what quickclock gave me, and for 1000MHz I've lowered it a little from the calibrated number.

    I've also been more conscious of turning off wifi when I'm out. With Apex and AOSP Liberty I could just leave it on and not worry about battery life, but CM7 is another story. I also make sure to turn off my phone when I know I won't be able to use it, like in meetings or movies. I really wish CM7 had a sleep mode like the stock Motorola GB has.

    I haven't used Quickclock yet. Can you limit the actually processor speed based on conditions? For instance with setCPU I have it so the cpu can only run at 300 while the screen is off. I have noticed a decent battery increase doing this. You may try that so you don't have to turn your phone on and off as often.

    The Motorola GB update gave you an option to sleep if you gold the power button. It basically turns your phone off, without shutting it all the way off, so it can wake up quickly without booting. I used it all the time whenever I knew I wouldn't be able to use phone.

    You can't set conditions in quickclock, I just am using it to calibrate the lowest "safe" settings for my phone. It runs tests to figure out the specific limits to your processor so you don't have to. I also have android overclock, but I'm not using conditions yet until I figure out the lowest possible settings for each tier.

    So on cm you can't just press the power button once and the phone sleeps? Without it giving options?

    Pushing the power button turns the screen off. Sleep mode basically turns everything off. You have to hold the power button to turn it back on, and then it takes a few seconds to turn everything back on and re-acquire a signal. I really can't understand why it isn't a standard part of cyanogenmod because it's such a useful thing to have.

    There really isn't much you can do on cm7 to improve the battery life.
    undervolting, limiting background data....none of it matters when all the battery drain comes from phone idle and cell standby

    To say the least...

    I've given up on CM7 for now, I'm going back to either Apex or aosp Liberty tonight. I need my battery life and camcorder.

    i use milestone overclock. it was a free app in the market i found while looking for droid OC replacements. you can move it up in increments with a slider and thats about it but its pretty effective. the first step you can OC it to is 1150mhz@70 and it bumped up my quadrant scores quite a bit, 300-400 points or so. i have noticed a lighter drain on the battery than droid OC gave me.
