Hello all,
my battery doesn't last as it used to and after checking, I can see even during the night, in flight mode, it is still losing around 20% per night.
I have GPS, WIFI, GSM off, I use Power Saving mode. I have no app installed.
It all started 3 weeks ago, I took my phone and it was surprisingly empty. Since then, my battery is crap.
Note that if I use the phone I can have more than 4 hours of screen time, but leaving the phone alone is killing the battery pretty quickly.
so far, these are all the steps I have tried without making any difference:
I have bought 2 new batteries
I have moved from stock 4.0.4 to Alliance rom 4.1.2
I have installed Jellybam 7.1 (4.2.2) without installing any app after flash
I have removed my SD card
I have disabled media scanner
I have calibrated my battery
I have reset the fuel gauge
I have flashed different kernel
I have monitored the battery usage with Better Battery Stats (dump attached in this post), and I can't see anything wrong (99.2% deep sleep)
--------------------------------------------------------------------------------------
I don't know what to do else... and I'm starting to wonder if it could be a hardware issue with the phone itself...
if you have any idea, I'm all ready to listen and try them.
If you have the exact same issue, please join this thread and post your S2 model, hardware version and steps you have tried.
If you are in the same case, did you have this issue happening suddenly ?
mine:
S2 GT-I9100
HARDWARE: smdk4210
also if you have a s2 and can comment of your battery stats during night in flight mode, it would be great so we can compare.
Thank you

Thanks pi-xel:
Some new observations,
I might have found something else, this led me to do the following experiment:
- Disable radio (airplane mode)
- Enable radio with data (WiFi disabled," 2G only" on)
- Turn screen off immediately after enabling
- Put phone *really* close to your ear as if making a call
What I experienced then were some very quiet, but still existent, clicking sounds coming out of the speaker that you might know from holding a phone close to a speaker when receiving a call or short message. I don't know whether this is regular behavior, but I would assume that the speaker should be turned off when not in use.
As I am not sure whether it should be like this, I would kindly ask users with and without our battery problem to reproduce the steps of my experiment and report their experience.
Thanks in advance!
Re: Battery drain in flight mode around 3%/hour
Just for the prove of it, go back to your ics backup for a day...
Use speedmod kernel on both,(assuming stock Rom).
It's not hardware..

Hi,
I had the issue with stock 4.0.4, this is mainly why I tried other ROMs.
I had stock 4.0.4 since around last summer, but the battery issue started 3 weeks ago, and still occurs even on a newly flashed ROM without anything installed.

Okay,I see, since you are on Stock, try the speedmod kernel.
Bbs shows your phone sleeps like a baby, my s2 consumes almost nothing in flightmode, even on android 4.2.2, I wonder if a dmesg could point to something..
Can you rule out the battery?

Hi,
thanks for helping,
I'm not anymore on stock 4.0.4, I'm currently trying my luck on Jellybam 4.2.2.
and like I said, I tried also on Alliance rom (so again, a different kernel) but same issue.
I think the battery can be ruled out as I bought 2 new batteries and it is still the same.
I'm having similar issues with the following setup:
Device: GT-i9100 (SGS2)
Rom: Rootbox Nightly 23.03. (Android 4.2.2, tried several 4.1.2 and 4.2.2 stock and CM/AOKP based roms)
Kernel: Dorimanx 9.12 (tried several dori + siyah + stock kernels)
Modem: XXLS8 (tried a whole bunch of different modems)
Battery: brand new original Samsung 2000mAh (tried 2 different 1600mAh stock batteries as well)
Carrier: Lebara over KPN Netherlands and O2 Germany
With all combinations I experience ~3%/h battery drainage, even in airplane mode. In airplane mode, my deep sleep ratio is around 98-99% as well.
However, it seems that removing my SD card led to some improvement in the drainage (not perfect, though). If you don't see any improvement by doing the same, maybe the issue is related to some files being stored on internal and/or external SD card (could it be that some wakelocks / processes related to media scanner service are simply not reported correctly in recent Android versions?). Did you try formatting both?
Besides, I see a high percentage of the battery wasted on phone radio (in Android battery monitor and in GSAM battery mon, that led me to try out many different modems - with no improvement). When I switch on airplane mode, this entry disappears but the overall drainage remains. Could it be that all the drainage that cannot be explicitly related to some process / part of the phone is collected in "phone radio"?

the SD is a good point, I'm ready to install the ROM again if I know how to delete all the files on the phone.
I did a wipe data, cache et dalvik cache before installing, but it is true I still have some files lying around...
You can format internal and external storage from CWM recovery (I would also backup all files to PC before doing this). Unfortunately, I currently need a navigation app on my phone on a daily basis, that has all the map files on my internal storage. Hence I cannot test it myself. But I'm looking forward to your evaluation

I'm going to remove my SD first before doing something I could regret
Do I need to reinstall the ROM after formating the internal storage ?
If the problem is really related to some files on internal or external storage, my guess is that you don't have to reinstall your rom. I would suggest to try removing external SD first, if this does not help, format internal storage, and if this does not help as well, then we should consider to do a clean install with empty internal and no external storage.
ok I did it... full wipe of everything.
My internal storage is completely empty, 11.48GB available out of 11.49.
I have removed the SD too et I have installed only BBS... tomorrow morning, we will see how many % are gone...

Ok, false alarm. I wiped my internal storage and removed ext SD. Then I put my phone into flight mode and left it alone overnight. The drainage does not seem to have improved (see new dump). What is interesting though is that the drainage does not change much between flight mode with 99% deep sleep on the one hand and sync with radio and wifi on and heavier network load over day with 96% deep sleep on the other. The difference is only around 0.3-0.5%/h. So there seems to be some constant source of drainage that is independent of phone activity.
But one more thing: I think you have made a very interesting observation: Although the battery drainage when screen off is huge, our screen on time still seems to be pretty good. My analysis is that if there were something draining the battery that should not be there when screen is off AND on, the 3%/h which we see during deep sleep would add up to our screen on consumption and thereby decrease our screen on time as well.
Thus my guess is that our battery problem is related to some component that should be on during screen on and that does not switch off properly when screen is off (eg. screen or GPU).
What are your thoughts on this?

ok, after wiping everything and flashing a new ROM (Jellybam 7.1), I have removed my SD, switched off wifi, gps, put my mobile in flight mode and left the mobile during the night. This morning, same again:
Level lost [%]: Bat.: -19% (84% to 65%) [3.1%/h]
I have attached my BBS dump file and a screenshot of the battery graph.
1 thing is very weird.. even if BBS says I have 99.8% deep sleep, I can see on the battery graph long period of Awake...
If I check the same with GSAM, the Awake is not displayed... so it is like the default android app see something more or is simply wrong...
have a look at the screenshot and the BBS dump:
I can confirm the long awake periods in Android battery graph. And I don't think that we have smartstay on SGS2, or am I wrong?

no we don't with stock rom 4.0.4 (and I still had the issue), but we do with stock 4.1.2 and some sammy based rom.
In my current rom, I don't have smartstay... and still have the issue of course...
do you see any difference on the graph at the exact same time as the awake shows ?
@megosu: What do you mean by "difference in the graph"?
@karpfenhai: As far as I understand, you also use GT-i9100, but don't have the issues we are experiencing. Could you maybe provide us with a BBS dump from your phone + a screenshot from Android battery monitor so that we can look for differences (if any)?
I mean, do you see the graph decreasing more quickly in your history at the same time it was "awake" ?

As far as I know, this bug is related to gingerbread and not by samsung, somehow it is triggered randomly (some say google maps, others say wifi or games) and the root cause is unknown, that's why some people haven't experience it, a quick temp solution is to restart the device but this is just terrible solution..if you are affected pls help spread the word so the issue becomes a high priority in google, the issue is already raised here since Feb 2011 and a lot of people have already experienced it (I myself experienced it):
http: / / code.google.com/p/android/issues/detail?id=15057
but it is still under medium priority, unbelievable! do you remember the SMS bug? google got pressured when it was spread in forums and news site..I think we can do the same here..let's raid android forums and android news site
here's the thread detailing the bug:
http://forum.xda-developers.com/showthread.php?t=1039696
it happened to me once...as you said before i restarted the phone and everythnig was normal again..
battery drain was due to wi fi sharing(although it was turned off)..and
dialer(dont know why...nearly 20% battery drain...) mainly...
I reverted back to KE2, factory reset, rooted, froze the bloat and getting phenomenal battery life.

Hi mate,
I used madmack's ROM which is based KE7 to enable Arabic.
What does factory reset means? will I loose all this setup? also how do you do the reset?
What would be my options if I want to keep madmack's ROM?
Kind regards,

The battery on my UK Vodafone supplied SGS2 doesn't last long.
The battery usage shows the following:
1) Android OS 54%
2) Email 20% (I have an exchange account)
3) Display 12%
4) Cell standby 5%
3) The rest is divided up as Phone idle and Android System
This is after just over 11hours of it being turned on, with a 3G, no wi-fi, gps or bluetooth, and the battery is nearly drained.
Does anyone know what type of usage accounts for 'Android OS'. I have no idea why it uses so much of my battery. I don't use the phone that much, i'm not playing with apps and fiddling.
The 3G signal is for my Vodafone Sure Signal. Since it's local to my house, the transmit and receive power is very low, far less than if I were outdoors with a 3G signal.
I wondered if the various types of Sync's that are performed in the background are what's accounting for 'Android OS'.
I've turned off the live wallpaper now to see if that improves things, just in case that wallpaper keeps cycling even though the screen is off.
I'm not getting the monstrous drains some are reporting, but still a solid 21% of Android OS plus 5% of Android System (whatever the difference is there). I can't remember exactly if my Hero had the same amount, but I think it was lower than that.
Got the drain. A factory reset fixed the problem, and I'm gradually re-enabling services and accounts now.
Just enabled my second Google account now, and the results are a bit worrying. I'll post back when I know.
How can you find out the battery usage??? I can't find it anywhere on my SGS2, I want to know too
Sorry, I've found it...
Mine is (without sim card, wifi on)
Android OS : 16%
Display : 14%
Android system : 3%
Phone idle : 2 %
Cell standby 65%
Yep I get it. Maybe we could start a poll?
For anyone else experiencing this battery drain: Factory reset helped A LOT. Doesn't seem to matter much which sleep policy I have for Wifi either, and all my Google accounts are added now. Will be re-connecting some more accounts and changing some settings gradually over the next days. I'll post back if I find anything that breaks my newfound battery life.

I had this problem on my S as well... seemed to happen randomly. Some days the phone would have stellar battery life, others it would die before the work day was over.
What's the point of doing a factory reset then loading up all the same stuff you had on it last time which will eventually lead you to the same problem?

I'm asking my own too.
i had the same problem as Madcow29 my cell standby is 70% without sim and wifi on. 22 hours and the battery was emty
I just have my new Galaxy S2 and first thing I noted is that battery drain overnight in flight mode is significannt. I had a ZTE Blade which stayed in same % even for a whole weekend in flight mode, using CM 7 or the best GB cooked roms.
I tried many ROMs, including stock XWKK5, XILA2 and custom, doing a full wipe install and in every case they typically loose 3-5% in one night or 8-10% in one full day. Only ROM that seems to keep battery most inf flight mode CM 7, loosing some 2% in 24h (but more than ZTE Blade). Next better is The-GingerMod 0.8. I tried killing every running process in installed ROMs but consumption is still high.
In ZTE Blade made no sense turning off the phone at night since startup lost more battery, but with S2 it's better to turn it off if still has battery for another day.
I can understand that phone has some parts always running, and that S2 has a large screen that consumes more power than smaller phones, but I find strange that in flight mode, screen off, everything off there is such a difference with the ZTE Blade.
Any opinion about this?
I tend to put my phone in flight mode overnight (~8 hrs/because I like to sleep when I'm in bed ) and I normally lose 2% (0.25% per hr).
At the end of the day it's easy to overthink/stress/obsess about losing a few % overnight when you've got easy access to a charger most of the time. What I mean by this is you can spend a whole lot of time trying to find/chasing that extra couple of % in battery savings & either not find them or maybe only find 1-2%.
Obviously battery drain will depend on a whole bunch of factors not limited to kernel, rom, how you have your phone setup (apps & so on).
You may be experiencing wakelocks when the phone is in flight mode that might be causing the drain to be a bit higher than it could otherwise be. Get hold of BetterBatteryStats. Install it, read the thread on here devoted to it & you can post your wakelock details to that thread. There's a bunch of guys who post to the thread regularly (including the dev) who might be able to help you nail the wakelocks & maybe squeeze out a few % of savings.
I installed BetterBatteryStats but as for now my knowledge is very limited to decipher the processes, anyhow as I said I tried many ROMs after full wipe being intrigued for this behaviour, so they were clean installs with no app added, but I see that even custom ROMs if they're based on official and no removed apps have many things added in comparison to the more vanilla ROMs the Blade has. This explains why CM 7 (or The-GingerMod) s the one that drains less. Have not tried 'lite' ROMs whith removed apps.
Just wanted to decide if it's better to turn phone off at night or just put it in flight mode.

i am currently using a lite rom based on XILA2 and i have to say it is the best i have used hands down. I never use flight mode at night or anything else. All i do is choose the governor of my choice and that is it. Some governors have a screen off profile. That saves you having to add an extra profile in the cpu apps if you use one. Anyway choose a rom plus a kernel that gives you great battery and stick a governor that has a screen off profile and your phone will sleep like a baby
Now that you've installed BetterBatteryStats, charge your phone fully before you go to sleep, do a reboot & leave it in flight mode overnight as you have been.
If you want to find out if it's possible to squeeze out an extra few % of battery, have a read of the BetterBatteryStats thread on here (search for it), read the first page or so, and the last 10 pages. That will give you an idea of what screenshots you'll need to post/what info you'll need to provide for the guys in that thread to help you out.
As to whether it's better to turn the phone off or put it in flight mode @ night, you should realise there's no right answer to that. It's your phone after all. Battery life isn't the be all & end all as I hinted in my previous post. Obviously if you want/need your phone fully on at night (normal mode), then you're going to lose battery & you'll be happy to lose battery because your phone will be switched on. It's entirely up to you.

I can be a lot of things besides the kernel itself, for instance:
1. Sensors! Turn off motion sensors...
2. The lower cpu freq is too high. Use the lowerst possible value.
3. The cpu governor it switching to the higher cpu freq to quickly. Try interactive.
4. Constant updates of some programs, like Twitter or Facebook. Even if there is no network connection they still run on their scheduled times. I just turn them off.
Hope it helps!
Hi guys, this is not an usual battery drain problem. I am more or less an advanced user of android but I´m writing here because I tried all my ideas and none of then worked.
I have 2 Neo V, stock. One day one of them started to have battery drain. Im talking about 6-7%/hour with no usage, the other one is around 1-2%. So with any use my phone don´t last more than 14h.
I started to check the usual(wifi policy, services running..), and don´t found anything, I switched the batteries between both to see if that was the problem but drain was still in the same phone.
I rooted the phone, tried BetterBatteryStats and CPUspy and all is OK, most of the time DeepSleeep etc.
After all I unlocked the bootloader with the S1tool testpoint etc and flashed some Cyanogen 9 rom + kernel, and the problem still persists.
I think there is nothing I can do and my phone is useless because I suppose I don't have warranty anymore.
Any ideas about what could be? Even if its hardware, what kind of hardware problem can make this high battery drain if the CPU is not working ?
Thx in advance
edit: In HTC we can also flash different RIL´s (radio interface layer) to improve signal db, avoid high battery consumes etc. There is something similar in NEO V? Because I didn´t find anything.
There are a couple things you can do:
1) Did you check that you had mobile signal all the time??, because losing mobile signal is THE biggest battery drain possible
2) Post some BetterBatteryStats screenshots so we can see what's happening under the hood
3) Try a different ROM/Kernel combination, that sometimes helps
And no, there's no RIL flashing here, just different ROMs/Kernel/Baseband combinations
I HAD the same problem
Even I faced a similar problem on my Neo V after getting FXP CM9. FXP 122 was fine. But FXP 123 and 124 drained the battery very badly(No considerable Deep Sleep in CM 9). So I switched to AOSP Polish blood. Battery life was excellent but it lacked customization, so I switched to AOKP v38+ AOSP kernel. Superb ROM but again not so good on battery (but better than CM 9). Yesterday I flashed the FXP 125 kernel. More than 5-6 hrs of WiFi, 15-20 calls and texting and some instagram and I still have 20%. I'm charging my phone now!!
I´ve uploaded some screens of bbs, cpuspy and batterydrain with wifi on and after switching it off.
Hope it reveals something, what really annoy me is the deep sleep activated most of the time, so I don´t really know what to search.
Just as I thought, what's happening to you is what happened to me a year ago and I thought changing phones would help.
Your problem is basically, bad signal, as you can see in screens 4,5 and 7,8 "No Data Connection" and "No or Unknown Signal" are preventing your phone from going into Deep Sleep, the problem comes from bad 3G signal (or just bad network signal if you don't have 3G) and that is known to basically eat up all your battery.
How is the network signal where you are???, because it looks like it's realllllyyyyy bad.

Are you sure? Take a better look.
Or at least deep sleep graph. And those graphs "No Data Connection" and "No or Unknown Signal", are also ok(ven though the name is confusing a bit), I have the same.
I'm not COMPLETELY sure but this is exactly what happened to me a year ago with a Samsung Galaxy Mini, also if you look at graphs 4 and 7 Deep Sleep doesn't have as much time as the data and signal bars, to me that seems like those two are keeping the phone in wakelock state more than it is spending on Deep Sleep.
I´ve been experiencing this problem for weeks. About signal I tried everything because:
- Phone worked perfect with SIM and all bars (I live in the downtown of a big city)
- When the problem started to happen I switched to another phone and this one was working without SIMcard so there was no signal at all.
- Some days ago I used another SIM which also have all bars.
I Don´t think there is a problem of the signal . Also in my other phone, and as you can see, Deep sleep is working fine.
I reread your first post and the only hardware problem that I could think of is a faulty battery, did you use to leave it charging all night??, because that tends to burn the battery and it does hold a lot less charge.
According to what I've read, everything seems to be fine software side, my only idea would be that you reflashed stock ROM and check if the problem persists, reflash but don't restore any data, the problem could be a misbehaving app.
I have 2 Neo V (my father´s and mine) I switched batteries, and the problem persist in the same telephone. Also both of them have less than 2 months, so batteries are new.
Also revised the voltage in the CPU and it is alright.
Well, the only thing left to check (IMHO) is a misbehaving app or service, maybe check for task killers or battery savers in the "broken" phone, those are known to eat up the battery like it's ice cream!!
I believe I have the same problem. I can't remeber when it started since I tried lots of roms,
but I flashed latest ICS from pccompanion with no other tweaks for some days and it
continued the same.
I also thought about bad signal, but at night in flight mode it also spent 40% of the battery.
With a good kernel, undervolting, 2G... I can get to 15% 20% at night.
I've also switched batteries with other neo's and no difference.
Phone is 5 months old.
Not sure if it might come from the rooting process. If I understand right, the 0% issue
that some were having was more of hardware issue (or I'm completely wrong?) Then maybe
there is also something related?

I believe I have the same problem. I can't remeber when it started since I tried lots of roms,
but I flashed latest ICS from pccompanion with no other tweaks for some days and it
continued the same.

0% was a software related error (flashing GB 2.3.3 after having 2.3.4 broke the battery gauge firmware), however that problem doesn't exist on ICS, I find it reallt strange that both your phones have that problem, I've had my Neo for 8 months and the most battery I've lost overnight has been 10% (with CM9 and really bad signal).
Maybe the best thing you guys can do is send your phone to service.
I have a similar problem with my mt15:
when I buy my phone battery was ok. about two days with intensive social use, no gaming.
5 months later, battery drain begins: deep sleep and 8% per hour , airplane mode 8% per hour
tried almost every popular rom in development forum ICS stock, codename, tweaked, cm7.2, cm9, jjhybrid, KA, ...
tried every popular kernel: stock gb, stock ics, alliance, suave, super, nightelf, cm kernels...
battery drain happens while phone ON, happens with airplane mode, AND happens with PHONE TURNED OFF.
I thinked about battery fault. replaced my battery with a new genuine one. Same results.
If I remove the battery from phone, IT does not drain. 24h later battery is still 100%
So my neo has a hardware problem I think. And there are many people with same problem. look for "neo battery drain while off"
Neo is a buggy phone. you can be lucky, or not. but many people has these issues or 0%batt.
I give up!
After sony abandoned x10 mini pro (random reboots, eclair), I had given another chance to sony with neo. I like sony designs, but Im really tired.
sorry about my creepy english
Try freezing "Calendar" with Titanium Backup and see if battery lasts longer. It helped for me.

about battery drain when phone is off
its not consuming your battery while its off
when you are turning the phone on
cpu usage will be on 100% to run all necessary sevices and apps and most use goes to get signal
that's normal
i suppose its aroumd 3-5% of battery consume
im not gonna be at the same side with you
actually neo is a wonderful phone
i beated the score of sensation xe in antutu benchmark with it
just google it around the internet
there will be some fix mate..
Neo is not buggy at all maybe yours but not mine
this might work for you
i just found it
1-flash build 42 official rom on your device
2-root the rom (there are plenty of ways around internet)
3-flash this kernel via flashtool forum.xda-developers.com/attachment.php?attachmentid=780407&d=1321113977
4-now turn on the phone its gonna show 85% of battery
5-install this forum.xda-developers.com/attachment.php?attachmentid=897721&d=1329003275
6-plug the charger into your phone
7-from the menu of app select start full charge
its gonna take 3-3:30 to be full
may be you've seen it around web
i translated it from a persian forum
HIT THANKS IF I HELPED YOU
In my opinion, a phone broken by a software update/downgrade is buggy.
About battery draining while off, not all neo have this issue, but mine is not the only one.
On the other hand, about power consumption while booting, if i remove battery while off, wait some hours, and replace, after boot battery is 100%
Sent from my JJ's Hybrid MT15i
I had this problem too, even when the mobile was off, the battery was drained...
I sent my phone to after sales service and now it's normal drain 2 - 3% per hour when idle. (I was on stock rom and kernel, never changed).
There is maybe a bad hardware series
Hello,
I wanted to get your guys opinion as I believe my phone may have turned defective and I really don't want to go down the Warranty Route as I'll loose the phone for weeks. And willing to try anything suggested.
So here's the problem:
Battery Draining at very high rates. On stock battery, I am draining about 12% an hour, after 6 or so hours my 15% battery capacity left warning turns on. I figured it was the battery, so bought a double capacity 4200mAh Hyperion Battery. Now my battery drain is at 6% an hour (which is equivalent to the factory battery considering the double capacity).
I am currently on XXELKC 4.1.2 Stock ROM. When I first noticed the problem, I was on 4.1.1. Figured I would ODIN, Wipe all cache's, and start clean. This has made no affect on battery life.
Here's what I've tried:
- 4.1.1, 4.1.2 Stock ROMs from Wipe - High Drain
- Airplane Mode with Location Services Disabled - High Drain, but 4.5% an Hour instead of 6% an Hour.
- Disabled all Samsung Apps - seemed to have little impact
- Disabling Google Now has made zero impact on battery life.
- 4.1.1 BBS revealed nothing - may need to try again on 4.1.2
Any ideas? Or is this sounding like the phone? Is it possible after a wipe the phone, when I re-enter my Google Credentials it is restoring some data which is defunct and causing high drain?
Note: Screen shots are with the double capacity battery taken right after a clean Odin upgrade to 4.1.2. Only ran Android Activation and thats it.
It looks like your phone isnt going to sleep properly. Try a custom rom/kernel.
Have you done a full whipe ?? If not, do so, and don't forget to make a back up first. It worked for me !

I had similar issues, I factory reset worked, and I also download rescan media root app to disable the media scanner which was my main battery killer.
WHen you do the factory reset make sure your phone is connected to the internet, so it will prompt google to store the apps you have and remote install when you sign back into the phone.
I have performed a full wipe but that had minor impact on battery life but I wounder if the Google Restore possibly restored an invalid setting. I will try this again without entering my credentials and see if there is a link with a restored setting. I will have to give the rescan media app a try as well.

Any specific kernel in mind. From what I've been reading no kernel seemed to stand up to magically solve battery issues without voltage drop or cutting services like Google now from the rom.
use better battery stats app to determine what is causing those wake locks.

I have attached a run with BBS for 1 hour. Nothing is really standing out. The phone was in deep sleep for all but 2 minutes. I did have Google Now and Location Services Disabled as that was eating away an impressive 10 minutes / hour from deep sleep. But my battery life only increased from 6% an hour to 4.5% an hour. An improvement but weak IMO considering the larger battery.
Results from BBS is attached.
I once had that kinda issue too
What I did was Factory Reset and that did the trick for me
How about trying the app CPU sleeper?

I've had this issue before on the i9100 Galaxy S II, where it didn't seem to matter what I did, it chewed battery just as soon as I put my Google account back onto the handset. I believed it was caused by the Samsung calendar bug. So absolutely; try it without putting your Google account onto the device.
Also, your WiFi signal looks low, although this has less of a difference compared to having low mobile coverage...

your first post has a huge amount of wakeocks that arent going to be reflected with an hours run on BBS. If i were you id charge it to 100%, unplug just before going to bed and then show us the BBS log in the morning so people can see whats happening over an 7-8 hour peroid

It looks like the same problem I was having. Your WIFI is always on.
http://forum.xda-developers.com/showthread.php?p=35813539
Also leaving your Bluetooth On all the time is going to drain the battery pretty quickly.

its not wifi always on, my wifi is always on too and i lose 2% over an 8 hour standby period.
Its more what apps are using the wifi connection and waking the phone up, thats what the op needs to look into
I have to say ive had pretty bad battery lately aswell. If op doesnt mind I might post my bbs log tomorrow sometime
tapp'd on my S3

More information can't hurt. Post in and Maybee there is a correlation.
OK. So I went ahead with your suggestions and did the following
Factory Wipe again from Settings Menu
Went back to factory Samsung battery for consistency in reports to other users
Took out both my sim and sdcard to eliminate those possibilities
Put into airplane mode
Disabled a bunch of apps (ss on next post)
Still bismal results but better than before. 7 percent an hour drain. Attached all the files. Ideas? Google says phone is awake but bbs doesn't seem to shed any clues for me...
And here are the disabled and installed apps
your phone isnt going to sleep at all....something is keeping it awake..try a stock rom ( any will do) with full wipe. Dont restore anything with titanium backup. Disable auto sync on everything. Set wifi sleep policy to always. See if the problem persists.

That last run posted was stock 4.1.2 XXELKC firmware and Factory Wipe from Settings Menu. I also performed Wipe and Cache Wipe in the Bootloader (Power Up + Center + Power). All I did was install bbs and never put in Google or Samsung credentials and disabled some stock apps from running.
If your not referring to factory Wipe, can you please explain further? Thanks.
The phone is 4 months old, I abused it at first (general usage + heavy games (dark knight rises, asphalt 7hd, deadzone, etc).
I then rooted it, installed custom roms eg FoxHound/WanamLite, used stock kernel until I tried Yank, Siyah and Boeffla. One of them, I can't remember which one, gave me about 24h battery time (over a month ago) with gps on, decent screen time (~2h-2.5h) wifi 40% of the time.
Now I don't know what happened but my phone just went mad. I barely get 10h with 1-2h screen time, mostly 3g, gps off, screen timeout 15s.
I am not using auto brightness anymore, I've got it set on the lowest by default, to make sure it stays at its darkest. I tried siyah with the extreme battery config. I'm now running boeffla with zzmove battery; all I adjusted was the sound profiles.
It drops by about 10% in 30 mins only from texting/browsing on wifi. My ram usage doesn't go pasy 650, it usually stays at ~580.
Hey
Give some more details like which rom you using and kernel.
Have you tried a different battery?
Plus have u gone back to the official firmware after facing battery issues?
Send from my Samsung Galaxy S III GT-I9300..!
If you have a custom recovery, wipe data, cache the whole bit...reinstall a fresh ROM..should solve the problem, seems the phone is awake more than it should...something went crazy software side...

I am currently using wanamlite 6.2 with boeffla kernel set on zzmove battery profile. I haven't tried a different battery and I had ~24h life with a custom rom based on the official firmware, FoxHound (not the official firmware).

I realized the phone stays in deep sleep for very little, about 5-6%.
I attached some screens, do you see anything that could cause this problem? I'd rather leave factory resetting as a very last resort ..
