Forgive me if this is common knowledge but I wanted to bring this to this forum because I didn't see it.
I did a complete wipe and upgraded to CM9 and noticed my battery life wasn't that great. Wasn't as horrible as it got on my CM7 -SGS1, but pretty bad. 9 hours a charge or so, which is enough to get through the day at least. On a tip I downloaded BetterBatteryStats(worth every penny) and started looking at my Wakelocks. I noticed AudioOut_1 was top of the list by an absurd margin. So I did some searching and came across a thread in the Nexus section(http://forum.xda-developers.com/showthread.php?t=1389214&page=3 and then to https://github.com/asksven/BetterBatteryStats-Knowledge-Base/wiki/AudioOut_1 Thanks Syn Ack).
Turns out there's an apparent bug that even with the screen off, it being touched can trigger a wakelock on the sound. Sure enough I turned off the Touch Sounds and Screen Lock sounds and I'm now losing about 4% an hour of light usage, major improvement.
Again sorry if this makes me an asshat, I just wanted to spread it to people who might be having this issue with their fresh CM9 install.

thanks for the info!
I get huge audio out wakelock too, ill try this out.
Interesting, I'm getting that same process at number 1 but both of those are already disabled for me.
Same here. But it seems like the duration is less than it was when I had sounds on
I'm going to play with this today and see how well it works. I'll post back tonight sometime.

Turn off wifi and battery life is great (on standby). Previously I had wifi on, battery drain 4%-6% an hour, but with wifi off, it drains only 0.8% an hour (95% battery after 6 hours of standby, randomly checking). This is on 3/30 build.
edit: I left wifi on.. 8% battery life drained within 1 hour and 30 min..

This sounds like you have an app installed that treats wifi data usage differently than cell network data usage. Gonna guess that you had a lot of wlan-rx wakelocks over that period of high drain with wifi on...

I totally agree, with each phone I run a simply test. I'll get to that in a sec. On my last phone "captivate" wifi was actually better than data on standby, but not this phone "SGS2". With that being said: I charge 100% then left wifi on while I went to bed. Woke up with 70% over 8 hours of standby not impressed. Next night did same thing 100% but with data on instead. Woke up with 95%!! ....I personally have up in notification bar data toggle and wifi, I leave data off most of the day while I'm out. I turn it on when I want to check email or FB etc. best amount I've lasted was 1 day 16 hrs... With 26% battery left. Ik some Ppl won't want to do that but just a suggestion. Hope this helps anyone out.
SGS2 Running CM9 using XDA
I unplugged and after browsing, making two calls, a text, and finding some places on google I checked an hour later and bam, I had 97% left. I can live with 3% an hour drain with high usage. I also keep WI-FI and Bluetooth on and have it connected to my car. This definitely fixed my problem, hope it helps everyone else.
My setup is nothing but stock install of CM9(3-30), stock battery and everything.
Well after using it for a full day. (14 hours) I can honestly say that for me. This hasn't improved anything. It hasn't made anything worse either though. I'm sitting at 28% right now. Which is the same as I was getting prior to this change.

ah so same thing, just not in this forum, like the other thread I posted
I did this on my phone yesterday, and it seemed to help quite a bit. After I first did the latest nightly my battery drained stupid quick, after this it dropped down to a normal level.
So yeah, turning off Wifi and the AudioOut_1 drainers, I'm getting 1% or less drain per hour on standby. Awesome stuff guys.

As this is not normal behavior, I'm going to suggest that you look for the app that is using your wifi. I leave my wifi on 24/7. Go to sleep with a full charge, wake up 7-8 hours later with only 3-4% gone.
What's probably the best way to go about doing so?

It stays on Wifi whenever I am at home then I switch to 3G when I leave. Brightness is set to Auto. I never turn on GPS, (that's what my Garmin's for) and everything sync's normally. It's weird, some days I'll get this kind of battery life and somedays I'll get a lot less. Even with similar usage from day to day.
I get about two days of use with everything on. (No gps or bluetooth) Facebook sync on, texting, web browsing xda app, and a couple short games. I don't ever have any battery left though..
If I stay home I have closed to 60% left after 18-20 hours of regular usage----a few calls, browsing, games and texts----but I have wifi and an airave

Simple. Take a screen shot of screen on time. Who cares how long your battery lasts, if you don't have alot of screen on time.
I read this trick from somewhere (possibly a myth?)
Charge phone to 100%
Unplug, allow 5% discharge,
Charge back to 100%

I'm not completely sure about this, but here is what I remember reading:
That was only useful on other phones when it would display 100% when really the battery was 90%. Doing this charged it to the maximum battery capacity. The Evo 3D stops at 100% when the battery is actually full so we don't need to do anything.
I think this phone does not register being plugged into the computer as being "plugged in." Therefore it does not reset the meter, and you get readings like this, even though there was some (computer-connected) charging in between.
Just wondering since updated to XXLPQ if your battery life has changed compared to 2.3.6. Mine has suffered a noticeable decrease in battery life as i can notice a number of extra apps running in the background compared to 2.3.6. Any input/solutions?

Better Battery Life
In stock gingerbread I usually got 1 1/2 day of life with 2-3 hours of screen on. With CheckROM v6 I got around 2 days with 4 hours of screen on. Now with ICS and CF-root I got with the first full charge 1 1/2 day with 5:30 hours of screen on!
I froze all the junk that comes with the ROM, I only have a partial wakelock AudioOut_1 that is driving crazy. So far I'm quite happy with it.
Please search the forum we have so many Battery ICS threads already!
Battery life is def better with ICS, have you calibrated your battery since the update?

I'm not having any real battery issues myself, but since quite a few people report it I decided to call Samsung and ask if they will provide a rollback to 2.3.5 or what they could do to alleviate the issue.
And the answer was, as a technician had told, to solve the battery issue I should do the following:
1.) Charge the mobile to 100%
2.) Let the device drain battery as "normal" until around 9%
3.) Then open applications that drain battery fast until the phone shuts off
4.) With the phone in off-mode and drained recharge it to 100%, and do not turn on the phone at all during this time
5.) Turn on phone, and the battery life should be back to normal
Seriously, this was the official answer I got from Samsung support technician. Sounds like some old woman's advice, but hey if anyone with battery issue want to try then why not. At any rate it can't hurt

Hi guys
I've been playing around with my galaxy s3 for several days and I'm very pleased.
But one thing is still very annoying as a previous iphone owner. That's the battery life.
I just attached a screenshot. For 9 hours 12% drains during sleeping thus basically screen has turned on for only few mins.
Is it normal??
Wanna hear you guys opinion.

Hello,
i don't think is normal here is my use over night.
It's without sync and wlan, with sync and wlan it takes 2-3%
If you turn off wifi, data and GPS and put the phone on energy saving mode (its on the top bar menu, just drop it down and you will see it) then after 8 hours the phone is almost 0% drain.

Thats correct. It seems like for most people its the cellular data that is killing the battery. If I turn off 3G data, I get good battery as well but with cellular data turned on, battery will not last a day.

you have something else going on i lose 2% overnight...try airplane mode see what happens
I think your charger may be broken lol. You charge it every night yet your phone is at 53% when you wake up? Anyway, assuming you sleep 8 hours and that your phone was at 100% that is less than 50% on 8 hours. You probably get 17 hours standby time, not the best but not the worst. Try airplane mode

I still suspect this may be router related though. When I had my crappy Netgear, I would get strange periods of battery drain on my SGS2 when WIFI was left on. That just about all disappeared once I upgraded to an Asus RT-N16 running Tomato, and now, I don't get any drain on my SGS3 as well when I leave WIFI (set to "Always On" under Advanced WIFI Settings) idling.

I too think it's router related. It can possibly be due to Wifi dual banding in some routers that support it. Faster internet with less battery life.
Awesome first charge.. plugged in Friday when I got it and just now 38 hours later I'm plugging it in. 4.5 hours of screen on at 85 percent brightness.. here and there browsing.. some photos.. gps enabled turn by turn a couple times.. SIRIUSXM for 4 hours at least.. fell asleep both Friday and Saturday night listening to Art Bell.. so at least 4 hours. Outlook checking mail every couple hours. Tested a few games for probably a total of an hour maybe. This is about average use for me. I would say this bests my note2 and that's a lot to say. Will it get better after a few more cycles? This phone is a keeper... loving the knock on/off feature and I'm getting really used to the buttons on the back.
Good stuff man....lower that brightness a little and turn on autobrightness and you'd be getting even better battery life. Doesnt the constant 85% hurt your eyes?
That's awesome. Battery life was a big reason I picked up this phone, and it has yet to disappoint. I'm on Verizon, so probably couldn't get the Nexus 5, but even if I could I'd probably go with the G2 for the battery. I like a nice bright screen as well
I took the attached a couple if days ago. GPS off, mobile location on, 65% brightness baseline with auto on. Mostly web browsing, with about an hour of talk time, and 3 hours of audio playing via Bluetooth. The battery really is fantastic.
However, there is something that can get stuck and prevent deep sleep causing excessive idle drain. Its happened to me twice now. A reboot clears it up, but I haven't tracked down the culprit yet to prevent it entirely.
Anyhoo, pics below.

Ive found 3 culprits for idle drain thus far:
*backup* - disable backup/ restore in global settings
Nlpwakelock - disable wifi/cell gps assist in global settings, and history anf reporting in Maps
CarrierIQ - disable it as per instructed in the carrier IQ thread

This was from my third charge. Gets better every charge. Basically full stock only debloated.

pretty insane results.. looks like it only gets better! On my second charge now.. still showing 100 percent after a few hours.. very little use though.

I found it takes a lot to get thought that first one percent. I had the screen on for 45 minutes before I dropped to 99% the other day. I'm starting to think there is something up with the battery gauge.

G2's battery life is very awesome...I got 6 hrs around screen on time for stock rom.
I believe if we get more tweaks, rom in future, it will get even better!

No... You're just using an awesome phone!
Yea the battery seems great when you don't touch the device but try playing a game for a little bit . Candy crush crushes ( ? ) my battery to hell.
