Same question here actually, did not find an answer yet...apart from: CWM touch version is closed source.
[T-Mobile, Samsung Galaxy SIII] Hairy07:
Hi guys,

Though I have been reading these threads for quite some time now, I just joined so that I can post the issue that I am facing.

I am rooted and using Liquidsmooth v2.4

I am facing a battery issue. Battery life is short. I never survived more than 2 hours of screen time on my device which I know from these forums that is not normal.

The stuff I have tried but didn't help:

Wiped and factory reset on several occasions, both using the settings function and CWM

Flashed various roms (Cyanogen Mod, Carbon, Liquidsmooth, Stock rom)

Unroot to stock and root again

Changed to various more battery friendly CPU governors

Changed battery with a friend who is using the international version (which is using the same battery according to the Samsung website)

I am not in the states now and the local Samsung service centre refused to service it because they don't have the appropriate parts and also due to the difference in software. (I unrooted it and restored to stock before sending in.) They just looked at the model number and refused service; didn't do anything more.

I have attached some screenshots. There are no obvious wakelock issues and no app in particular is draining the battery. 50% power used on screen appears to be normal. The rest of the apps also look like they are behaving themselves, at least power consumption wise. I am not a very heavy user and don't run any games/apps that are huge in resource requirements. Email/facebook/browsing are my main activities.

The current settings on my phone:

Auto brightness

Wifi/bluetooth/GPS all off

Autosync is off by default but will use it sparingly if I need to.

Almost all of my apps have their notifications off and all apps are set to sync manually.

I only have one calender widget on my home screen, no others elsewhere.

CPU Governor is "ondemand", iO scheduler is "row". Min/max freqency: 384/1512 MHz

Juicedefender is enabled with "aggressive" (I know its effectiveness is controversial but on my device, disabling it eats more battery)

Any help is appreciated. "Thanks" will be awarded to all who post!

Thank you!

I see horrendous wakelocking. Install BetterBatteryStats. Charge it up for a bit, reboot the phone, then let it idle for a couple hours. Then post screenshots of everything.

It might be the worst I've ever seen. Good news is it's probably not a hardware issue.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
It also looks like half the time you had a poor signal. Data transfer on a poor signal can wat at your battery too.

Always use wifi when available.
[T-Mobile, Samsung Galaxy SIII] Hairy07:
thanks folks. I've installed better battery stats and will update shots accordingly at the end of the day or end of the battery cycle(probably won't last a day)

Really appreciate the help.
[T-Mobile, Samsung Galaxy SIII] Hairy07:
Here are the shots for today.

I rethinked about the poor reception comment and wondered if any of my radios are malfunctioning or if my radios can work in the frequency bands here in Singapore. I called my local service provider to ask about the frequency bands and.it appears that my device's radios can recieve the GSM bands here although they suspect 3G may be an issue. Nothing concrete but I do hope to find out if that could be a possible reason for my battery drain.

I managed to squeeze past 2 hrs of screen time today by using as much wifi as I possibly can. This improvement in battery life probably means that data reception can really be an issue. It's not unlikely that both my home and workplace suffers from.bad reception but i do have a Q. If poor reception is an.issue, will the battery consumption by cell radio sky rocket?
[T-Mobile, Samsung Galaxy SIII] Hairy07:
For some reason the previous battery stats screenshots was only for about 5 hrs. i have refreshed and have uploaded the refreshed screenshots
[T-Mobile, Samsung Galaxy SIII] Aerowinder:
This is not BetterBatteryStats. We already know your battery life blows. I want to know

why

, and BBS will tell me. I can't do a thing for you until you show me that. I think there is a free version on the forums, but it's cheap in the Play Store, and worth it. Get Greenify, too. You're going to need it. Greenify will prevent notifications from showing up for greenified apps. If you don't need notifications from Facebook (honestly, who does?), Greenify it. Maps, too. And disable Juice Defender for now, so I can see what is really happening.

Poor cell reception, if not on wifi, causes drain, yes. It seems to only get really bad when the phone can't hold a data connection.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Try turning off GPS. Also under Settings > Backup and Reset, turn off the Back Up My Data option.

Additionally, check the stickies in this forum. Woody has a fantastic Battery Thread that you should read if you haven't already.
[T-Mobile, Samsung Galaxy SIII] IXChicharitoXI:
Type betterbatterystats xda on Google. It'll link you to the official thread where you can install the free apk file.
[T-Mobile, Samsung Galaxy SIII] Hairy07:
Thanks everyone! I sheepishly searched better battery stats on Google play and.simply installed the first that popped up without looking closely. My bad. I've purchased the app and will post up screenshots soon. I didn't manage to grab the shots today as my batt went flat before I could. Should have kept a better eye.

Will certainly post up screen shots tomorrow.

PS: My GPS has been offed by default. Will disabling Google backup services help?
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
It cant hurt your battery life! Theres a number of things you can do for settings. Read woodys thread stickied here as its pretty much all there. One of the big batt drainers can be auto brightness btw.
[T-Mobile, Samsung Galaxy SIII] Woody:
Once you get a good cycle run with BBS, the screen shots we want to see are Since Unplugged/Process and Since Unplugged/Partial Wakelocks. Those two will help tell what is eating your battery and also what is causing all those wakelocks in your original screen shots.

If you are using Juice Defender, that will contribute to the wakelocks (but doesn't keep your device from entering Deep Sleep, so no worries there). I use it, but I have mine set up custom plus have done some basic build.prop edits regarding the RILs and wifi_supplicant_intervals.

My suspicion is that there is a rogue app that is transmitting data somewhere and that is not letting you sleep. If it is transmitting in a poor reception area then that puts ever more strain of things. You are not the first and wont be the last but Doc, Aero and I can help you figure it out.
[T-Mobile, Samsung Galaxy SIII] Hairy07:
Images for today. I've included a few more shots for the items that appear lower in the lists.

I've installed greenify but did not add any apps while collecting these data. Juicedefender is also disabled. My screen time was less than 2 hrs.

I did some of the stuff listed in Woody's informative thread. Deleting the tombstone files, lost&found files etc.

Thanks for everyone's help. Hope to solve this issue soon.
[T-Mobile, Samsung Galaxy SIII] Aerowinder:
Get Greenify from the play store.

Greenify:

Maps

Facebook

Google Now

Take more pictures with BetterBatteryStats tomorrow.

Looks like Maps is misbehaving. Terrible coding is terrible.
[T-Mobile, Samsung Galaxy SIII] Woody:
Yup. Looks like you are broadcasting your location all over the place. Do you use Maps? If not close it and Greenify it.

Are you getting notifications from Facebook or have a "Check-in" thing going on?

Google Now>Settings> turn off what you don't use.

Settings>Location> Off.

Edit: Tombstones and Lost.dir files are just memory management and have nothing to do with battery.
[T-Mobile, Samsung Galaxy SIII] Hairy07:
Shots for today. Things are a little better but looking at my screen usage, maybe there's still a lot of room for improvement.

I've greenified just about all apps that may run in the background. Facebook, Maps, Google+, Gmail, Chrome, Google Search (I converted it into user app), dropbox, etc. Whatsapp, Viber and Wechat are spared as I needed them to be able to notify incoming messages. Juicedefender is on, with advanced settings - set to sync only once an hour. Maps have been set not to update my location although I didn't go to the extent of denying location access ( I use maps fairly often).

All these are rather aggressive steps and I do see improvement. What else can be done? Other than my messengers, all my notifications are essentially off.

Once again, thank you everyone for your time and effort.
[T-Mobile, Samsung Galaxy SIII] Aerowinder:
Please stop using Juice Defender. I want to see what your battery life looks like without it now. And it's also responsible for the majority of your wakelocks. And if you could get us some ~4 hour idle BBS stats (during sleepy time), that would be fantastic.
[T-Mobile, Samsung Galaxy SIII] Hairy07:
Noted. I'll charge my phone up and take some shots in the morning. Juicedefender will be disabled and hopefully more information will be revealed. Do today's shots show any improvement?
[T-Mobile, Samsung Galaxy SIII] Aerowinder:
I think you are heading in the right direction (8% deep sleep improvement). For this next test, please disable Juice Defender (don't turn it off through the app, but disable it in the app manager to make sure it can't run). Also, I'm hoping to get a test where the screen isn't on for more than a couple seconds, so I can get an accurate reading on the usage per hour.

I suspect the rest of your issues (bam_dmux_wakelock), are due to a bad cell connection for a good chunk of the time. Connecting to a wifi network will solve that. If you don't have a wifi network, you can turn on airplane mode, or set up some Tasker profiles to help with that.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Out of curiosity, how bright do you have your screen set? Obviously its a big drainer, but it seems like every time your screen is on the batt level plummets.
[T-Mobile, Samsung Galaxy SIII] Hairy07:
these are the shots for 4 idle hours. Didn't use the screen except for snoozing my alarms. Juicedefender has been uninstalled.

My brightness has always been set on auto. Bad signal might be a problem for my home seems to be a 3G deadzone. But that's only for the time I'm at home. It shouldn't be that big a problem when I'm out, especially outdoors.

Once again, thanks for everyone's kind efforts.
[T-Mobile, Samsung Galaxy SIII] Mr. 5Theezie:
Dowload Greenefy from the market it will help greatly
[T-Mobile, Samsung Galaxy SIII] Aerowinder:
Thanks for reading the thread before responding. This post has been most helpful.

That looks pretty good to me. What kernel where you on again?
[T-Mobile, Samsung Galaxy SIII] viktex1d:
I think you should do the following : 1.disable vibration 2.switch to gsm only mode when you're at home 3.use the battery saving app called one power guard. Seriously, it is the best. The next thing you should do is try using an application like lux auto brightness as I hear and see a lot that the default auto brightness in android is a bit quirky.

---------- Post added at 10:37 AM ---------- Previous post was at 10:32 AM ----------

You also said that you don't use any heavy applications. I recommend that you underclock your device. Or set the maximum frequency to less than the maximum. I have read through your thread and am recommending. I don't basically have an s3,but my cousin does. I am just trying to help you.
[T-Mobile, Samsung Galaxy SIII] shahkam:
Sometimes i flash a rom and get horrid battery life and if i reflash it gets little better but your issue seems weird how many charges does your battery have ?

Might be the charger getting too old ? 2h of screen on time at max is a joke for a 2100mah battery... I get more then that on my sensation 1800mah whit over 220 charges...

Perhaps extended battery could help you out aswell ?
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Try using it with auto brightness off and keep the level as low as is comfortable. It looks to me that you screen is the primary source of drain. Especially if you were at 90% after 4 hours minimal use.
[T-Mobile, Samsung Galaxy SIII] Hairy07:
Really bad day. Screen lasted just an hour.

Is 10% drain over 4 hours of doing essentially nothing considered good?

No juicedefender, auto brightness, with greenify.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
In comparison to your other posts, it seemed a lot better. Besides, wasn't it actually at 96% after 4 hours? I'd say that's perfectly reasonable. And I could be wrong since screen on time also means other things could be going on as well, it just looked like your battery would take a dive whenever screen was on.
[T-Mobile, Samsung Galaxy SIII] Aerowinder:
Couple things:

1) Your LK is old. http://imoseyon.host4droid.com/s3/aosp/#!/view=details/lang=en/sort=na. Here is the parent thread: http://xdaforums.com/showthread.php?t=2226290

2) Looks like your phone had some syncing issues while it was in a bad signal area (GTALK_ASYNC, RILJ).

3) Did you reboot your phone since the last test you showed us? You may be having the same problem I'm having.
[T-Mobile, Samsung Galaxy SIII] shahkam:
Data will eat all the battery i speak of experience and best bet would be to update your rom your kernel cycle 2-3 charges and if it still doesn't work buy the official 3000mah extended battery or an aftermarket
[T-Mobile, Samsung Galaxy SIII] SGSIIIUser:
Is his battery life consider bad? Because that about what I get with my stock battery with stock everything rooted. But I have location service on because I actually like Google's feature. I now have the Zerolemon 7000 mah extended battery which will last all day no matter what.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
I'm on stock battery and unless I play any power hungry games, I can easily go all day on a charge. And its over a year old.
[T-Mobile, Samsung Galaxy SIII] Hairy07:
1. I've just updated to the newest stable kernel and hopefully things will turn out better.

2. I've greenified just about all the stuff that can sync without my knowlege and in addition my auto sync is off. I.duno how else to prevent unauthorized syncing.

3. For some reason, the phone rebooted by itself sometime yesterday. it isn't deliberate and i think i might have lost some bbs data cos of it.

4. I've now set my brightness to the lowest and only upping it temporarily if i need to use it outdoors. It doesn't that much dimmer than auto brightness but it could be subjective.

5. I know for a thing(from these forums and from frienda using S3) that 4 hours screen time is easily achievable. Some are even just using touchwiz and not even using stuff like juicedefender and not limiting syncing.
[T-Mobile, Samsung Galaxy SIII] shahkam:
Results so far ??
[T-Mobile, Samsung Galaxy SIII] Hairy07:
My unfortunate phone restarted itself yesterday and I lost all the bbs data. But it didn't seem anywhere close to 4 hrs of screen time(more like just 2+). In fact, i don't really know what else can be done already. I duno if Chrome can be a problem since it seems to use a significant amount of juice after screen and cell radio.
[T-Mobile, Samsung Galaxy SIII] Hairy07:
Shots for today. Not cool. Bad signal can be a problem but unsure if it can cause such massive drains
[T-Mobile, Samsung Galaxy SIII] Aerowinder:
I've seen what your phone can do (1.5%/hour). I'm all but certain now that this is your problem: http://xdaforums.com/showthread.php?t=2315554. It accounts for your good readings, your bad readings, and your total confusion as to why this is happening. It's a bug in the ROM, kernel (it's in the CM kernel if so), or firmware (MD5). If the issue isn't resolved in a couple days, I'll build a LJC firmware package and flash that. See if it helps any.
[T-Mobile, Samsung Galaxy SIII] Hairy07:
Really thankful for the help so far. I hope it can be resolved.

I have some Qs though. If it is CM10 kernel giving issues, it will seem that changing kernel or using the default kernel that comes with touchwiz would make things better. I did unroot my phone before and restore to the stock touchwiz but it didn't get better.

Secondly, good readings????
[T-Mobile, Samsung Galaxy SIII] Aerowinder:
The issue may be baked into the CM kernel. And you can't use TouchWiz kernels on AOSP. By good readings, I meant that I've seen your phone can be reasonable when it comes to battery consumption. But it's not being consistent. Which is the same problem I've been trying to solve for weeks now.

I put together an LJC package last night and flashed it. Battery usage went down to 0.9%/hour (after I was using the phone - didn't reboot). I did not get to thoroughly test it because it was super late. I updated nightlies this morning, so I've messed up my test bed. Though I could downgrade for a night, I suppose.

I'm going to ask you to flash the package I made. It will take you back in time to LJC. I am starting to suspect the issue could be MD5. Which is why a lot of people aren't complaining about the problem.

This zip file has built-in error checking, and I've tested it myself.

Remember to only flash this if you have an SGH-T999: UVDLJC time machine.
[T-Mobile, Samsung Galaxy SIII] Hairy07:
Thanks! Flashed and keeping fingers crossed!
[T-Mobile, Samsung Galaxy SIII] Hairy07:
Things didn't actually get better....

The 4 hrs idle shots. I'll allow the battery to run till it's flat. But the drain isn't pretty. 87% after 4hrs of doing nothing will not exactly make anyone proud.

Thanks for everyone's kind efforts but more troubleshooting is definitely needed, unfortunately.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Sorry if I missed it, I just skimmed through again real quick, but what rom/kernel are you currently running?
[T-Mobile, Samsung Galaxy SIII] Aerowinder:
How is the drain over 4 hours with airplane mode now that you are on UVDLJC? It really looks like a signal strength issue now.

You're BBS stats look good. I notice your signal bar going from 3 bars of G, to no bars of 3G. Time is the same.
[T-Mobile, Samsung Galaxy SIII] Hairy07:
My rom and kernel info are in the screenshots.

I'll charge up the device and put it in flight mode before uploading the shots. Signal is an issue when I'm at home really but it can't explain my other drains. Most of the 4 hrs was spent outside. only perhaps the last 20min, at most, is at home.

Very very disappointing here. A mere 30min use of the screen and the batt has been down to near 30%. This is bad, real bad. I really appreciate everyone's help but I'm not sure if it's time to suspect some hardware issues.
[T-Mobile, Samsung Galaxy SIII] TristianX:
Two things of interest - I had the same issue with my SGH-T999 32GB, I thought it was battery wear/conditioning at first so I bought a few different batteries including a new oem battery but the behaviour continued. I then factory reset my device thinking it may be down to a troublesome app but again no success. In the end it turned out to be an issue with the actual handset - the device was using way more juice to do normal things leaving me with horrible battery life. I rma'd the handset and at the same time got hold of a Galaxy S4 which has great battery life. (I also grabbed a HTC 8X as a backup device in the event the s4 starts to misbehave!)
[T-Mobile, Samsung Galaxy SIII] awyeahh1:
Same issue
[T-Mobile, Samsung Galaxy SIII] Hairy07:
Flight mode readings are really good. 1% drain over 4.5hours.

But, as usual, battery plummets rapidly after flight mode is disabled and screen is back on. In fact, uploading these pictures alone took 4%.
[T-Mobile, Samsung Galaxy SIII] Hairy07:
To get an idea of the extent of the drain and explore possibilities of signal issues, there are some shots that I took.

30min screen use (auto brightness by default) and with good signal strength(mainly green and I'm outdoors throughout) saw a drain of 17%. At best, this extrapolates to just under 3 hrs of screen use for a full charge which is still unsatisfactory. Improvement, yes but still crappy.

Bad signal can cause drain but I duno if these shots can eliminate bad signal as a main cause. Really seems like something else is up to no good.
[T-Mobile, Samsung Galaxy SIII] Aerowinder:
If you disable Facebook and... WhatsApp is it? If that doesn't help, it has to be a hardware issue.

BBS looks good. Deep sleep is a little low, but acceptable.
[T-Mobile, Samsung Galaxy SIII] Hairy07:
My greenify list is

Chrome

Dropbox

Facebook

Firefox

Foursquare

Google Search

Google+

Gmail

Maps

Outlook.com

I didn't include whatsapp as i need its notification.

If hardware is an issue, I really need to send the phone back to the states. It's annoying to say that very least but if the local samsung refuses to even take a look, it is inevitable. Everyone who contributed to this thread have been helpful. Especially Aerowinder, DocHoliday77 and Woody. If there's more that I can do, please kindly suggest. Maybe trying a Touchwiz rom? I unrooted to stock before and battery was worse.
[T-Mobile, Samsung Galaxy SIII] Woody:
I agree with Aero, you Deep Sleep does look good. I don't use Chrome (I know, I know) but I do know that there are some power intensive apps out there that just devour your battery, like say Tapatalk.

Let's just say that there are some extra ordinary things happening on XDA and I need to be made aware of it. If I have both Tapatalk and GTalk open working the problem and banning trolls, I will take a huge hit on battery from both those processes. Singularly, both of those are battery intensive, but double them up and that makes for a short battery day.

There have also been times where I have been on wifi using Tapatalk just browsing around and in 1 hour, it will drop 8-10%. Same with GTalk, especially if I am involved in a multiple person chat (it is constantly polling for responses).

I say this because maybe Whatsapp and Chrome are your bigger battery drainers since you either Greenified or disable all your other suspects. Does Whatsapp have a setting to determine the notification polling (5m-15m-30m-1h-2h)? If so maybe you could span that out. Not sure about Chrome's syncing either (again because I don't use it), but IIRC one of the appeals of Chrome is that you can sync your bookmarks across all devices. Can your phone sync be spanned out like I mentioned for Whatsapp?
[T-Mobile, Samsung Galaxy SIII] Hairy07:
I kinda suspect chrome may be an issue since it is the biggest drainer after screen and cell radio but Chrome is also an often used app, which means it makes sense for it to be on my battery list. However, Chrome has been greenified since I used Greenify and I never set my phone to autosync (unless when needed and usually very sparingly). I could uninstall chrome and see if that helps.

For Whatsapp, it doesn't even appear on my battery consumption list and if it does, it is usually at the bottom few. Can it be suspect too?
[T-Mobile, Samsung Galaxy SIII] Woody:
I just saw the Whatsapp on your Partial Wakelocks screen.

The thing about Chrome is suspect is that when it isn't being "used" it is sleeping just fine. When it does click on and you are browsing, that is when the massive drain occurs. This is what I was alluding to in my Tapatalk/Gtalk above. They are intensive when in use.

I wouldn't uninstall it. Maybe give Dolphin or the stock browser a run for a few days and see if things either pick up or shift from Chrome to one of them.
