Don't overlook the AudioOut_1 wakelock. Its my number one offender at the moment.

Minimize it by turning off screen selection sounds... System Settings / Sound / Touch sounds.

We need to figure out what the problem is with that.

On the good side, my mmc and deleted wake locks are negligible so far on beta.

Same for me. Think due to notification sounds mostly.

That's probably right. The only time I ever see that is playing music without headphones. I almost always have my phone on vibrate

Just want to say THANK YOU for this thread, and THANK YOU for such am awesome rom.

If I might be so bold to suggest, put a section on your page for "If you get worse battery life on this rom than your last rom, it may not be because of a problem with this rom, it may just be that way and there may be nothing that can be done about it because that's just the way it is."

I have had no problems with battery life, fwiw.

"Without a doubt, the biggest battery saver for me, is to turn off data until I want to use it."

Just spend a day with CM9 Beta 0. It's a great rom with lots of promise. Great feel and look, very fast, ICS is fantastic.

That said, the battery life is not there yet. I basically set it up the same way I set up the stock rom. Email on Exchange push notification, EVERYTHING ELSE on manual sync. On a stock rom I usually am at about 40% after 12 hours of moderate use. About 5% drop an hour. On this rom I was at 75% after 2 hours. About 12% an hour. This is with the "stock" 1800 mAh battery.

If the devs can match the battery life of stock GB I'll be back. It really is a great rom, I just can't recharge twice a day, and I'm not carrying around a 3500mAh battery in my pocket either.

Seriously, great work to all the devs who have taken it this far. Looking forward to the next couple releases.
Novatel Bagphone, Motorola Microtac, Qualcom Q-Phone, Motorola Startac, Sanyo MM-8100, Sanyo MM7400, Samsung A900 Blade, HTC Touch Pro 2, Sammy Epic 4G,

Currently Sammy Galaxy S III running Stock Rooted KitKat 4.4.2 because it's just that good. Knox don't scare me

I simply cannot believe the difference. Makes me think I'm gonna have to go out and get Juice Defender, and let it turn off data when I put the phone to sleep, it is just that dramatic.

I can call text, and play hours of games, and still have the battery have more juice remaining than it did over the same timeframe with just a call or two for usage with the data on.
I use JD for this and run it in extreme mode, which disables data until you physically enable it yourself (and after you enable it, it will disable again when the screen is off). Using it, I get a huge improvement in battery life, especially on CM9. It's kind of annoying having to enable it everytime you turn the screen back on, especially since it takes 4-5 seconds before data works again, but if it can give me the type of battery life it does, I am all for it. Other than the slightly noticeable lag I get compared to CM7 and other ROMs such as CleanGB (I know I can install supercharger, but I am talking pure stock CM9 here), I have no problems at all. Major props to all the developers involved for breathing new life into our OG Epics.
