So basically...
I had originally bought my S2 with Cyanogen Mod 7 with the latest Gingerbread update.
I wanted to try out ICS, so installed a couple of ROMs but didnt like it that much so decided to reinstall the previous CM7 with CheckROM RevoHD V4...
On the first time I bought it and whilst playing around with ROMs battery life was great, but now that I have reverted back, the battery life is obismal.
Last night my battery went from 100% to 25% in about 6 hours of being on, mostly in standy, screen brightness at the lowest setting and hardly any use (kept turning it off to conserve battery)
Whilst my friend who has the same phone, running stock gingerbread was only down to 78% and his phone was on ALL night.
The battery stats show display useage as over 80% for me atm and im really confused, thismorning my phone has been off charge since 11:30 and in 3 hours its already down to 75% whilst idling and texting a couple of times.
Any ideas whats going on?
Install Better Battery Stats, seems like you have wakelocks.
http://forum.xda-developers.com/showthread.php?t=1179809
Then post up a log of that.
Secondly, what kernel are you using and it's settings?
Xwkk5
2.6.35.7
After installing a beta test rom that is not yet released i would do a full wipe of the phone then install stock rom ..

Is there something I can do without having to shell out money for it?

You are looking for partial wakelocks over a 24 hour period .

Do I need to leave it running on battery or what?
Yes. Don't leave it on charge. Charge it fully before you go to bed, leave it running on battery overnight.

Ok, will do.
Ok, so left it on overnight and all day without the charger...
I had the display on lowest setting, and useage was very rare as i didnt wanna risk it dieing on me.
By the end of it, my battery was at 7%...
Time since plugged in - 21hr~
Useage :
Display - 61%
Android OS - 17%
Android System - 8%
Cell Standby - 6%
Phone Idle - 4%
Kik messanger - 2%
Messaging - 2%
Have attached the 4 logs.
What does all of that mean, anything i need to fix?
I am not expert, but it seems that while your phone is left, you have folowing wakelocks:
CommunicatorServiceWakeLock (kik.android.Kik Messenger): 27 m 26 s (1646 s) Count:312 2.2%
FMRadio Service (com.sec.android.app.fm.FM radio): 23 m 7 s (1387 s)
You should stop one of these applications, and than repeat all the process of fully charging the battery. Then look again what is eating our battery.
As I said, am not expert, so maybe I am wrong. But, after using Better Battery Stats, and disabling auto sync, now my battery last like it s not smartpfone. For example, this morning i took it from charger - I had today 15 calls, 7 messages, litle bit use of internet (wifi is turned on non stop,...), no games,... my battery after 14 hours is at 77%.
Kik Messenger seems to be doing something while your phone is supposed to be sleeping. Try uninstalling it, and see if the situation improves.
Right as mentioned above, you have 2 major apps that are cuasing your phone to be kept awake.
Kik messenger & FM radio service, as you can see here:
CommunicatorServiceWakeLock (kik.android.Kik Messenger): 27 m 26 s (1646 s) Count:312 2.2%
FMRadio Service (com.sec.android.app.fm.FM radio): 23 m 7 s (1387 s) Count:1 1.9%
KikNetwork (kik.android.Kik Messenger): 6 m 27 s (387 s) Count:676 0.5%
kik.android (): Wakeups: 580
For Kik either sign out when you are not using it or freeze it with Titanium backup or uninstall it.
I guess you use the radio as well so shouldn't affect it that much.
Not sure if this is also affecting your battery:
com.google.android.apps.maps:MapsBackgroundService (com.google.googlenav.networkinitiated.NetworkInitiatedService)
Active since: 1 d 2 h 29 m 6 s
Last activity: 12 h 57 m 39 s
Crash count:0
Google maps, you can see it's been active for quite a while.
I suggest you grab Gemini app manager from the market, change to advance mode and disable autorun for Maps. So it won't autorun when you start your phone. Also disable any other apps you don't want auto starting.
To sum it up, you've got a smart phone, enjoy it make use of it and remember we can always charge on a nightly basis

This is not a battery thread. I just wanted to do some maths based on some findings of my own.
I post this screens, taken at 50% battery. I rebooted when full battery for a fresh graph. I'm running "stock" 2.3.4 KG1. Data is always on, two push mail accounts, display on Auto, no gaming, no photos for today.
So, if the graph are accurate (I really doubt that):
1. 17 hrs 38 mins total time on for 50%
from this:
-1 hr 48 mins phone calls
- 45 mins Android OS
-1hr 2 mins display on
-Android system (the thing responsible for widgets, push mail and so on, basically for apps) 7 mins 50 secs!
-Phone idle 16 hrs 35 mins. TIME WHEN NOTHING IS SUPPOSED TO BE RUNNING IN CPU FOREGROUND
- Navigon comes up with 11% BUT I NEVER USED IT- and there are no details on CPU usage either.
- I used 20 mins of sync Wifi for the later part of today, wifi doesn't show on the graph- no clue why.
Here I stand pretty puzzled:
1hr 48 mins of calling + 16 hrs 35 mins of idle is 18 hrs 23 mins! assuming that idle does not include when calls connected and screen off .
Here are the figures for the AOS and how life would be without it.
Android OS chewed 14 % of the 50 % battery. Calling ate 43% for 1 hr 48 mins. If it wasn't for AOS bug, I would have had power to call for some 36 more mins to get to the 50% battery. That's like 30% more talk time without the bug.
Display, set on auto, drained 10% of power for 1hr 2 mins. Android OS bug stole almost 30 mins of display time for every hour . This is 50% wasted power.
Phone Idle is 4% for 16 hrs and 35 mins. So, basically, every minute under raging AOS eats 0.31% of battery. for every 1% the phone idles for 4 hours and 9 mins (and ideal stand-by time of four and an half days ). EVERY MINUTE OF ANDROID OS EATS AWAY 1 HOUR AND 22 MINUTES.
Also, the Widgets and all other stuff are actually consuming half the power eaten away by AOS.
So, if by miracle, the faulty driver is resolved by Samsung, we should get :
30% more talk time
50% more display time
350% more idle time.
Or, for the connoisseurs:
Android OS comes in, battery goes flat. No miscommunication. You can't explain that.
Good post, my own experiences (i only have my GS2 a few days coming from a HD2)
I deleted my battery stats last night and left my phone on,data was enabled nothing like bluetooth/GPS,etc,brightness is set to automatic brightness the phone was at 99% and from 12.29am to 09.59am this morning when i checked it was 83%,not too bad i suppose but could be better, i have fast dormancy disabled and i froze the Samsung apps with Titanium Backup,however the Android OS was at 41% and Maps and Cell Standby both 15%, since then ive been using the phone for some Internet, 1 call and sent a few text messages and it's now currently 12.41pm and it's at 47% and the display now shows at 35% and the Android OS is 23%, im running Lite'ning ROM 1.5, does this seem normal or quite excessive im in 2 minds myself, does the Android OS usually be as high as that when in standby,when im using the phone for a period of time it appears to go down as low as 8%.
All I can say is, use ATK. Its just working great for me.
Regards.

Thank you for this. It makes the problem clear to see. There are a lot of people saying things like "it all adds up to 100%" or "hey Android OS is high, but my battery life is very good".
As you say, we'd get much much better battery life if it weren't for this damn bug. Battery life can be good now. However with a 1650 mah battery, without Android OS wasting precious energy, it would be great...
Great summary!
More info
I have depleted the other 50% of battery so I'll post the values. The phone charged when connected to transfer the files. Well, at the end of the day, it looks like the that:
1. Voice calls drained 39% of battery for 3 hrs and 19 minutes.
2. Display is 2nd with 14% and 2hrs and 20 mins.
3. Android OS gets 3rd place with 12% and 1hr 20-this is the kernel running.
4. Android System- the one you bought the phone for- is pretty shy, only 9% . I repeat, here are all the widgets, Sammy updater, mail and so on.
...
Dialer is 6%, Navigon gets 8%, Cell standby - that's the radio FW- 5%
Phone Idle is the champ with 3% @ 31 hrs and 17 mins. That's the spirit.
Also, GPS status is eating 2,2% for every minute.
Bottom line: if it wasn't for the AOS, I would have had -see below( let's be real and give each process it's share so I'll split the AOS drain to get everybody happy)- before running for the charger .
1. Phone calls. 5.6% more battery- and 23 minutes more of talk time.
2. Display. 1.7% 22 minutes more.
3. Phone idle 0.9 % almost 10 hrs.
The rest of ~4% is shared for Wifi, Cell Standby and android system.
These numbers are valid for my usage pattern, phone calls all day long/ that's why i bought a phone for/.
I might draw some lines here and reveal some facts ( the values might be different according to usage pattern):
ONE MINUTE OF:
AOS bug drains 0.15%
Voice calling (I live on a good network signal area) depletes 0.13%
Display on is lower than calling @ 0.10%.
GPS could be chewing 2% when polled thoroughly.
Widgets and other Sammy crap are not scary at all. In fact, I find them pretty decent under this SW revision.
Maybe some will find these values useful.
Maybe we don't realize the impact of implementing a bad driver. For me, it all makes a lot of sense and annoys me more. Too bad we not on Icrap's ship, the news would have been all over the web.
One last thing though.
There are 2 main issues withSGS2: AOS and wake up lag. Never listen to any wise guy that says the lag comes from deep sleep and you should be lucky if you have it because it means the phone is SLEEPING and not eating away battery. I've noticed lately a trend in trolling this issue. I am confident that the guys behind this reasoning are on the same level with the guys that came up with Killing task managers and empty ram crap in Linux. And they even wonder why the alarm is not working after RAM flush.....
Wake up lag is a side effect of some nasty crap hogging the CPU's front bandwith. I bet any trolls here that when the lag is gone so will the AOS bug be ( at least AOS will be under Idle in %).
My wild guess is a radio issue somewhere.
same problem omg :S i hate this !! but phone is great !!
KG3 Report
Hi,
I have a new report to post, this time under KG3 stock rom. This time WI-Fi off whole time. I used the car dock for 10 mins.
1 day 7 hrs and 57mins from full charge to 15%:
Voice calls 2 hrs and 35 mins -37 %
Display on auto 2 hrs and 27 mins 20%
Android system 13 % Cpu total 10m 16 s
Android OS 9% 53 min 45 s
Dialer 6% C
Cell standby 6%
navigon 4% pops up,never used it
Phone idle 4%
Although it seems the AOS got less cpu with this, the improvement is not so clear. I almost talked 1 hr less with this one.
My android is 49% of 15 hour up time from last charge but the CPU time is only 2 hours 15 minutes for it. Hardly 49% of up time. Do you think maybe firstly there is no bug, its a bug with reporting not AOS usage time and that the phone hardware just eats a lot of juice even in standby. Just a thought. The battery lasts pretty good for the fact that its so small, there's an amoled screen and a dual core processor. Perhaps even in idle the hardware just draws a lot of power to allow a quick jump from standby to fully activated without any waiting around.

Could you post some screens?
Android system is 49%? the percents relate to the battery usage, not the time.
ALSO VERY IMPORTANT:
Dual core CPU should draw less power in standby/idle/sync. this is the idea behind dual/quad cores. If you have the time, read on how do they stack processes.
Deep sleep is not working properly. How come my WIN7 x64 wakes up in less than 1 sec from standby> win kernel is around 300 megs vs 17megs Android? It is a driver issue.

Believe me, I've tried the highest official way there is. They keep blaming android/google. I even pointed them some apps that were using obsolete scripts and 4-5 ro.* that were hogging the cpu. All they answered is that is under revision. then somebody from the work asked me what the f*** is this communication about and told me to use the nexus S instead.
Here the results of a simple test I did:
KG3, CF-Root, 8 widgets, skype and viber, 2 e-mail accounts. The usage was roughly the same (mostly internet browsing, e-mail cheking and only a few voice calls 20min approx.) The difference is that in the first day I left the sync and WiFi on all the time. On the second day, I left both sync (including background sync) and WiFi off most of the day, except during the time which I was using it (browsing internet, updating market apps, checking e-mail, etc.) The result, as you can see in the screenshots below, is that with sync and WiFi off, I've got almost 26h extra of battery life (18h18min v 1d19h52min). So, for me at least, the battery drain is WiFi+sync.
Looking at the pictures, compare phone awake v screen on. With sync+WiFi, you'll see that the phone was awake many times with the screen off, whereas it didn't happen when the sync+WiFi was off.
Therefore, I think it is better to turn sync+WiFi on only when you really need it, and not all the time. That's what I'm going to do from now on.
Ah, no powersaving settings enabled in any case!
Android OS @2%
Still under KG3, nothing installed lately, nothing at all:
Full battery in the morning almost flat in the evening with very light usage- I on a sort of holiday ....
1. 16h and 2 mins it lasted
2. 57 mins of calling
3. 51 mins of display time
4. Android OS WAS 2 % running for a total of 3 mins
REALLY SAMSUNG?
I want my AoS back.....
i rooted the phone yesterday, screen on time was around 4 hours or so..10% drain per hour average with screen on-off.
freeze all bloatwares and aos went down to less than 10% (was in 40s).
will see battery improvement today.
after root, i still got the yellow rectangle at boot (havent remove it yet)..will it affect battery life? any input?
I froze the WIFI Sharing service and my phone went from dying 25% over 4 hours at work with almost no use (and WIFI off) to lasting all day, or not charging at night and lasting all night and through the next day.
Just saying.

If you don't understand that the yellow triangle ONLY means that the kernel you have flashed does not have the correct signature (i.e. it is a custom kernel) then you shouldn't really be messing with root at all. How would this be relevant to the AOS bug or to battery life?
What is your view on juicedefender?
Battery savers are pieces of **** that turn help battery life by constantly changing the device on something more like Nokia soap.
My Personal view on software that claim to help save on battery was/is as it is about task managers on Android... somehow useless mainly for a few reasons:
1. They interfere with running processes and I haven't seen one really optimized for the system. Some are behaving limiting the performance. Which isn't a good thing.
2. I found that even Watchdog is a drain culprit when it's running after a limbo limbo process.
I have seen this issues before, in PC world. 8-5 years ago, Sony was loading their Vaio series with so much crap that the laptops were slow as a turtle right from a start up. They failed to listed then and lost almost 60% of their market. Others reacted faster and gave the option of removing crapware ( mainly proprietary sofware and trial) when ordering [ btw,of course, anybody could do it by msconfig but few were willing to mess it...].
I can't get it why Sammy, HTC, LG won't offer a barebone/unified Android. We could all get what we need from Market and this is why we have the markets war.
I don't want my update service running in background, nor do I need email app from Samsung...in order to get them off my back I need to root, Edit a file and make sure I mount the right permissions( or BUY something to do it for me) and so on, most people don't want/can't root , not mentioning the longer the chain the more links likely to break, including the warranty is voided ...WHY all the fuss to stop something I don't want?
Microsoft hit the nail in the head with their approach to WP7 (except closing it like Apple). That's because they had to deal with screamers for 20 years and they have a clue about crap ruining an OS.
And yes, I am still waiting to see a dev coming out with a pure Android Rom on whole XDA.... for any device. They all add something to it....a tiny tweak or a tiny thing.
Today i noticed a crazy drain my my battery than previously recorded.
Here's a TL;DR except from a battery meter report.
2011 Dec 20 07:28:50 1324402130 72
2011 Dec 20 10:03:50 1324411430 61
2011 Dec 20 12:33:51 1324420431 30
Based on this, the 2.5 hours from 7.30 till 10.00 the batter lost 11% charge from 10.00 till 12.30 also about 2.5 hours, the battery lost 31% charge. Just wondering if anyone else experienced this today (or recently) and has any advice on what i can check for.
The only app i know of that updated today was Google+. Has anyone experienced today's update being more of a battery hog? If so, is there a way to downgrade?
Thanks

Thanks for the reply. Darn. I was hoping on something easy to blame... especially since i knew i updated that app today. but yeah.. 30% in 2.5 hours is pretty unacceptable... especially when i've gone 24+ hours on a charge before.

Someone else suggested that the Facebook App might have activated the GPS and left it running. I'll have to play with that and see i guess. Make sure the GPS is off and test the battery.
I wish i could go 24 hours on a charge, current battery, 4h 49m - dislay 50% 1h 11m and phones been charged a few times probably 45 mins charge. Now at 16% that's usual too... idk if its a straight talk thing or what but its ridiculous, first android phone and i miss my iphone 4's battery life.
I have been running the latest Unnamed, and it was running perfectly until I actually installed and ran a BLN app (though I was also running Llama, a location-based profile modifier.) Started from scratch with a fresh Unnamed, and battery life is back to normal...10h batery, 58% remaining, display 41%, Android OS 30%. It was either BLN or Llama causing Android OS to take the majority of my battery...I assume a wakelock issue but I did not do any further investigation.

I've also been experiencing horrible batter life lately (bought it 3 weeks ago). I'm at 18% after not even 10 hours. 20 minutes of calls, 15-20 texts or so, 3 email accounts. Bluetooth on for a couple hours during my commute.
I'm stock and unrooted (until I decide for sure I'm keeping the phone).
I uninstalled Facebook, NoLED, Skype, turned of Hotmail calendar sync and GPS as per the battery life post.
I have Google on autocync for gMail and Calendar
66% in Deep Sleep.
I do run Executive Assistant (<2%), but it's way too useful for me not to use it.
I was getting ~20 hours last week. If anything, I've ostensibly made changes for better battery life. I have no idea what's going on.

I read that thread or at least part of it when i first got my phone .)
Main reason i asked separately was because the battery drain just suddenly got x3 worse than what i'm more used to. I kind of panicked. Will try and do soem further testing as time allows.

If you haven't already, download better battery stats to see if there are any offending apps or wakelocks that are causing the excessive drain.

Yep, did that (awesome app, BTW). The one that took up the most time was the bluetooth PBAP, but it was 2 hours which is my roundtrip commute to work. Nothing else seemed to take up a significant amount of time other than the sver stuff. Although I guess those small things add up. I think NoLED was a huge culprit. People seem to love it, but perhaps I set it up wrong. I'd like to re-install FB and see if it really wasn't that big of a battery hog.
Anyway, after uninstalling those apps I mentioned above, I'm at 90% after 5-1/2 hours. Yesterday around this time I was probably somewhere around 60%. I'm still using Executive Assistant for 3 email accounts with frequent autopulls, active sync for Gmail and Google Calendar, and a few phone calls. I didn't go to work today, so that's 1 less hour of BT for the morning, and I've cut down onmy screen time but it's still a huge improvement.
I just may keep this phone after all.
GOOD NEWS EDIT:
I'm at a little over 24hrs with 43% left! Granted, I curbed my use to try and get a hold of what was going on with my battery: 30 min of calls, only 45 min of screen time, and a boatload of texts.
I realize the screen time is minimal, but it's an amazing improvement on my idle drain, which was the biggest problem. My phone actually goes into deep sleep! I forgot to check the % before I went to bed, but in the past, if I didn't plug in my phone at night with at least 30% charge, it was usually dead in the morning, or with single digit %s.
As far as I can tell, the culprit seemed to be NoLED. (Not trying to slam it or anything, because it's a cool program, but I'm pretty certain that was the issue.)
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.

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?

Hi there,
I've been noticing that I've been getting very poor battery life on my new S3 both on ICS and now on JB. After some googling I found the problem of S3s not going into deep sleep when left idle so I installed BBS and sure enough, overnight when not touched my phone went from 100% to 18% (9.6% drain per hour). I have the statistics and it was awake for almost all of this time. I can't yet post screenshots as a new member but I was hoping somebody could help me get to the bottom of my issue.
The total time since unplugged from 100% is 8h 12 mins 21 s as a reference point.
Other:
Wifi On 8h 11m
Awake 7h 35m
No Data Connection 3h 34 m
Good signal 3h 27m
Deep sleep 36m
Screen On 2m
Kernel Wakelock:
PowerManagerService 7h 19m 89.4%
multipdp 1h 17m 13.2%
alarm 58m 12%
secril_fd-interface 51m
l2_hsic 34m
wlan_ctrl_wake 33m
wlan_rx_wake 27m
Partial Wakelocks:
AlarmManager 2h 24m 29.4%
MediaScannerService 1h59m 24.3%
Maps app:NLP PendingIntent client in googlequicksearchbox 1h 23m
SignalCollector.ScannerThread 25m
NetworkLocationLocator 13m 22
CPU states:
1GHz 7h 9m
Deep Sleep 36m
Process:
Maps wakelock
media wakelock
android.process.media

Finally, the battery tab in OS settings says that Maps used 29%, Media 23%, gpsd 16%, device idle 10%, cell standy 9%, screen 3%, Androis OS 3%, Androis System 2%, doubletwist 2%.
I know that AlarmManager can mean a lot of things but is there any way of finding out without rooting my phone?
Any help on the above would be appreciated as I'm getting pretty frustrated at losing 10% of my battery an hour.
Thanks.
So why isn't this in the Galaxy SIII section?

Ye, this belong in the S3 forum.
Anyway, are you running stock kernel?
Was your wifi /gps/data on?
Tried to reboot? Wipe cache?

I think so but I'm not entirely sure what the stock kernel is. I've not rooted it and updated to JellyBean through an automatic software update so it should be the standard one.
Wifi GPS and data were enabled all night. I was at home so it would have been connected with that. GPS was not active at all during the time according to the battery stastics.
Have tried rebooting. Just wiped the cache there.
If it helps at all I've noticed that often it seems to display the SD card symbol when I turn on the screen, don't know if that has something to do with the mediascannerservice wakelock?
Clearing the cache and rebooting again hasn't helped.

Which jb rom firmware are you using?..llb?? . The jb leaks and the first jb official roms of the s3 had media scanner wakelocks .. the media kept on scanning the sd card for stuffs even when not needed.. it can be solved by going to settings..manage apps... media storage.. clear cache.. ....

Kernel Version 3.0.31-368423
Android 4.1.1 which installed automatically via software upgrade option in settings. I'm on Orange UK.
Unfortunately in media storage it says cache 0.00b and no option to clear.
I tried turning off a lot of sync and changing email poll frequencies. This morning, same again. 82% drain in 8h 12 mins. However this time alarm manager was responsible for a very small number of wakelocks. Mediascannerservice was by far and away the biggest culprit. Any ideas to stop this short of formatting my SD? I tried clearing the media storage cache but it wouldn't let me.
Hi mate,
have you managed to solve this yet?
I have had my phone a few months and the battery life was OK.
Since upgrading to JB it is terrible - im losing about 10% in standby mode.
I have been looking around at a few things to try but i want to leave my phone in standby for an hour to see how much i am losing and where.
This is my first Android phone and although i love it the battery is a lot worse, for me, over my iphone 4 - with the same usage.
A question i have for people - when i had bad battery on my iphone i restored it in itunes and set it back up again. This seemed to fix the issue.
Should i do this on my S3? Have people managed to get a seemingly bad battery to perform better with a restore?

I did a factory reset and the problem was gone. For a few days it worked absolutely fine until last week, when I spotted the battery draining excessively, checked BBS and noticed that media scanner was back. I hadn't added any media files for a while before or installed any new media applications. I cleared the cache for all media applications and it seemed to fix the problem again for about a day but then it came back. I'm really frustrated by this as I can't seem to stop the mediascannerservice from sucking up all my battery life.
OK so i left my phone untouched for 1 hour and 5 minutes and I lost 11% battery!
Any ideas guys?
FYI - the phone was in standby with no apps running for 1 hour.

I have read that this can be due to a faulty mp3 track.
I would suggest removing all your media and see if you still have battery issues.
If you dont then I have no idea how you would find out which track has the problem?! Do a chunk, check battery and then filter them out that way!

Thanks for the suggestion but after reading that issue elsewhere on this site I have already tried that including going as far as formatting the SD card completely.
Not much help on these forums are there?!
Im gonna try and reset my phone tonight to see if that fixes the problem.

Try charging it and then letting it run for an hour from when you unplug it as that'll give a better indicator. Those usage statistics there take in to account all your usage. If you don't already have it you could get better battery statistics to help diagnose the issue. I believe it can be had for free somewhere around this forum.

Yeah i installed GSAM battery monitor as well and it showed me i was using 11% in 1 hour 5 minutes.
It is telling me that Exchange Services is using 20% of the battery. The thing is that I have always had this on since I had the phone but my battery only seems to be getting worse after JB update.
Just to update this thread. My battery is now MUCH better. I think it was the 2 exchange email accounts I need to have.
I completely restarted fresh and everytime I load email i then clear the RAM. This has helped hugely!
Hope you manage to sort your problem out.
I'm having issues with the media application as well. Now sure what the hell it's doing, but from a 100% (powered off) charge, I dropped to 95% within 10 minutes. GSAM says Media is taking 54.5% of the battery... lovely!
Sadly, the biggest issue with this is that the phone never deep sleeps, so if I am below 40% battery before I sleep, there's a big chance my alarm won't go off in the morning...sucks!
I'll do some more research on this and report back if I manage to fix it.
Update 1:
Removed my card and let GSAM monitor usage. Surprise, surprise! Media went from top drainer to bottom of the list (actually showed as -2.8% lol).
Put the card back and in and mounted it, and media immediately jumped to the top of the list.
Currently in the process of backing up my card data. Gonna format it and put my stuff back and see what happens.
Update 2:
Yeah, formatting seems to do the trick, but as I soon as I copy across my camera roll, it starts flipping out again. Not sure what's going on tbh.
Hello! 1st sorry if this has been awnsered before.
Very briefly, my phone only lasts about 150 hours on standby ( 1% drain in about an hour or little more )
Ive searched everywhere and couldnt find an anwser. Im familiar with the case of the xml profile or what its called xD and its not the case
Specially considering that otherwise the phone works perfectly ( I get about 4 to 6 screen hours on 3G using facebook, browsing, various games, etc ) I have also watched a 1h 26 minutes film on max brightness and only drained 20 %
But the standby battery is not what it used to be. When I 1st got the phone, I unplugged it at 7am and it stayed at 100% till like 2pm, delivering the claimed 700 hours of standby time
Now, I unplug it at 7am and by 11am its at 97 with 0 use at all ( I kill all apps and wifi and only check the time every other hour lol )
I didnt flash it or install a custom ROM, using ADW launcher now,but this happened before I tried a new launcher. I have used battery stats app thingie, it said facebook drained the battery, uninstalled it, same thing. Only thing I can think of is my apps parafernalha ( Nearly 9 GB occupied of the 11 available lol )
Any ideas?
Thanks in advance
Yes your post answered multiple times .
Download and run Better Battery Stats as your starting point .
You are looking for wakelocks that keep the phone awake .

Wow, and I thought my battery life was OK until I saw this
I get about 96 hours with nothing running on background, I will try to improve it now.

Wow, my battery life just increased by many months by doing that :silly:
No, seriously now. I care about standby consumption because it takes away what could be some hours of useful usage when you're around, it only makes sense trying to improve it.
Turn off auto-sync, disable location services, low brightness, power saving mode, airplane mode when not using, delete apps you don't use, don't use messaging apps, etc.. And keep your screen off
I downloaded BBS and Ill leave it idle over night, see what it does
