Install BetterBatteryStats. That should give you some clues as to what's causing the drain.

Added Screen shots, please ignore media player and usb. I took screen shots as soon as I notice strange stuff but somehow system showed the screen shots duplicated so I deleted duplicates. Later I noticed I deleted the originals (most probably there was one c to begin with but gallery showed me duplicates, which is strange ).
New ones are taken after apprx. 1 hour of XDA browsing & listening to music.

open BBS app then press soft menu key ones then select more and in that press Dump to file
then u see the log file in ur internal sdcard, post the same so that it can be checked to determine the wakelocks causing batt drain

Gladly....

I think I have a possible culprit while searching for suspend_backoff
I found this http://forum.xda-developers.com/showthread.php?t=1697899 the phone model is different but I decided to turn wifi off to test and my battery consumption is almost like flat line when I'm not using the phone now (Data & synch is still enabled ). I do not know what causes this but I am not trough yet. I'd appreciate anyone to ID the source of the problem and how to overcome it (other than keeping wifi off) or should I switch to another rom

I have the same problem as you, but I think it is related to the (known and not yet solved) problem of the "dirty WiFi network", as it happens only with my office WiFi and not with my home one...
However in my case the problem is intermittent, while I always have the same high drain under the office WiFi, the major source of drainage changes, sometimes is suspend_backoff, other times it's deleted_wake_locks...

I also had a feeling it might be wifi. I'm not sure what you mean by dirty wifi but. My home network seems to be suffering from dns problems. Also when I go to work one of my customers has a proxy while other has a unprotected wifi with web login. in both cases phone is able to connect to wifi but not to internet.
I also considered this might create some drain but it is too severe. I even thought my phone battery to be dead.

Sudden Battery Drainage

I understand all these battery drain issues that the prime has been having but haven't actually had them, until now. I used to lose about 2-3% overnight but suddenly I am losing around 15% because it won't sleep. I go into the battery setting and it shows it been awake the whole time. Now I am sure if I looked around I may find a fix but it just seems a bit odd that it has just suddenly occurred. And its not a wifi drainage issue as I usually put it to sleep at power saving mode and wifi off. Just asking why?
Thanks,
I think it could be the Asus weather widget which I had set at 1 hour refresh rate.
if this just recently occured out the blue, likely a rougue app or something you recently installed. an app running in background or sync is likely the culprit.
Just put Skype on it but that's not signed in most of the time
every android tablet and phone i have does this occasionally, and those occasions are when i either play video or music. some of these media players employ a wakelock that will not disable after you put your device to sleep. sometimes a reboot will work, sometimes not. most of the times the reboot keeps it from draining. even force quitting all my media apps wouldn't work.
so basically i reboot every time i use any type media player so i don't get the drain - netflix doesn't require it, dice and just about every music player does. i'm not sure it this may be your problem, but it may be a possible solution.
I find that making sure to check the last two settings under Asus Customized Settings helps this. I was waking up in the morning to find my dock dead everyday before I checked those two settings. The only down side is when I turn the screen on and wake it up, it takes about 5-10 seconds to connect to the wifi. No biggie.
Use better battery stats and see what is causing it. I have read that skype does drain battery pretty bad. And even if you're not connected it still runs in the background at start up. Another app I would recommend is Autostarts. It allows you to disable apps at start up. I know system tuner is free and has the same functionality but I find Autostarts better. With ST, you just disable the app at start up, with Autostarts you can disable it at start up, shutdown(which some apps fire when the tab is being shut down and other system events), also other events. Like some apps fire up when you get a text, or when your connection changes etc.. I just think Autostarts has more options.
Also dev Entropy has a thread in the GS2 forums about know battery drainers. Some of it applies specifically to the GS2 but there are a bunch of general battery killers listed
http://forum.xda-developers.com/showthread.php?t=1308030
If you go to setting and battery it should show you which is using the most battery. The first one on top. If its android system, you can click on it and it will show you a list of whats been using your battery which may point you to the culprit. In my case, media was the only thing in the list. And I know if an SDcard is inside my dock it will drain battery. So after removing it the drainage went away. Havent had the drain issue since. Again yours might be different so check the battery usage.
Thanks for the feedback guys, the first thing i am gonna do is charge it up after it fell flat right up to 100% then try some suggestions. I am thinking a reboot could help it.

Problem with S3 Battery

When i fall asleep i just place my phone nearby the bed and its on airplane mode,wifi closed,data closed and generally no apps running(i think so).The battery is level (ex)50% and when i wake up,about 7 hours later its always about 15-20%.why this happen?
I checked the battery manager just after i waked up and the first was screen(56%) and after that adobe reader(10%)

Better battery stats does not work.dont know why.and i made my own post cause i cannot find the solution of the problem on other posts.try to be more polite to your answers
have you tried downloading the xda version of the better battery stats? if not here it is
http://forum.xda-developers.com/showthread.php?t=1179809
Is your phone rooted? Like others said, try to install the xda-forum version of BBS but it's weird because I did install the one from GPlay.
One of the first lead is the WiFi? Is it always turned on? There's a bug with it. Go into the advanced WiFi settings and set it to 'only if activated' (I don't know the exact spell in English but it's something like that).
But you better have to dl BBS & check the wakelocks.

what?
Underclock when you're not using your phone.
That will save battery.
If ur using stock TW. Put on power saving mode
PM Me if u want to know more.
Try using an app called easy battery saver and only use the cable and plug that came with your galaxy s3 it works for me, today I had eight hours after charge and using internet with 3g nearly continuously.
You would get much more by leaving it on standby.
Also restrict your background data, turn off your automatic updates at play store andturn off WiFi while screen is asleep.
Follow all these for better battery.
Use any battery investigation apk/widget (I'd recommend battery monitor widget) and look what is causing the drain...
may I guess: cell standby or gpsd?
guys i remember you that the cell phone is on flight mode with wifi,gps and data turned off
and, if you have a soft which contains a bug - you'll have such processes running.
It is up to you to install any apk which will contain more detailed statistics what actually is consuming so much juice.
If you do not want - no one would force you.

I have the exactly same problem,30% drain overnight.That happens after updating to 4.1.1 JellyBean.With ICS never happened.
Go into the battery page, click on the graph and then post a screenshot of the detailed graph here. It is usually an app or process not letting the phone go into standby. Happened to me when I had my phone on ICS out of the box. I fixed that all up through the individual app settings and all was sweet. Then when I went from ICS to JB, the issue came up again and I had to go through the apps again to change the settings back. It seems that by updating from ICS to JB, certain settings get set back to default, which then does not allow the phone to go into standby.
Culprits that I have found are:
Facebook - set to manual refresh interval
Weather (or any weather widget) - manual refresh interval
Google play store - Turn off Google AdMob Ads
Any form of newsreader (I was using Pulse) - Turn off notification when there are new stories
Wifi advanced settings - Set Keep Wifi on during sleep to "Always"
Samsung account - Turn off sync
Samsung app store - Turn off Update Notification, turn off push notification, turn off ad preferences.

Maybe some apps running in background if you are using *viber* delete it
It makes proximity sensor always on.
Try delete apps like that

Guys please keep in mind that keeping the stock os without any custom kernel might be not as effective than using an adequate custom rom...
In addition remember, cooler temperatures cause ur battery to lose its charge faster...
So if ur phone is placed on the window shelf and its getting cold during the night it might cause ur battery to drop fast..
I made this observation with my sgs plus....
Hope i helped.

[Q] High battery drain on stand by when wifi is on

Well, that's the problem, I'm having a very high battery drain on stand by when wifi is on and don't know how to solve it. I've tried a lot of roms and I have the same problem (only Omega didn't have this problem for me, consume was normal). The drain is about 5 or 6% per hour, while just lose 1% per hour with 3G/ HSDPA. It's really strange.
Sorry if it's been commented, I searched in the forum but didn't find anything.
I'd really thank any help, as it is very annoying. I post here a screenshot of a night time with wifi on.
Are you sure you don't have any background apps running from the wifi or any widgets that stay constantly connected to the internet? Seems to me as if this is not a problem with the wifi but with apps.
long press the middle button until the open apps pop up and press the trash can. See how this affects the battery life.

I have just made a clean installation (wiped everything) and I'm going to leave wifi on tonight without any application installed (except system apps), so let's see if that's the problem.
Thank you very much for your answer

[Q][CustomROM] Ridiculous Overnight Battery Drain on CM10

Greetings,
I had been using my Xperia Neo V with Cyanogenmod 10 (10-20130519-NIGHTLY-haida) for the last 2 months. It was all ponies and rainbows for me for the first 6-7 weeks.
Issue:
Now I'm facing with a random and ridiculous overnight battery drain issue since a week ago. Ridiculousness here is being referred to the amount of the drain (almost 60% overnight) and to the fact that there's no particular change of use of the phone by me,comparing with the days before. As you can see in the screenshots, the main actor here is "Operating System". I don't really know what this drain is related to, so I was not able to do comparisons of use.
Facts:
-Mobile Data was active but only at 2G
-Location services were off
-Bluetooth and all other possible signals were off
-No active apps, all were hibernated with Greenify
What might be the reason of this problem and what would you advice me to try?
Thanks in advance.
what kernel are you using? overclocked?
maybe you can try re-flash the rom
60% overnight is way high battery drain
You should try to see a pattern. Does it happen after specific usage "ritual" or just purely random?
It may be kernel bug/core system bug. Try dumping dmesg and logcat when it happen next.
I would start by trying to flash other kernel.
Install BetterBatteryStats (ther's an SDA thread); It will give you better info of what is draining your battery. In addition to that, you can post your logs in the thread (BBS thread) and they will provide better help.
Good luck
Edit: here's the link http://forum.xda-developers.com/showthread.php?t=1179809
Install wakelock detector app uninstall those... Try greenify too
Firstly we have to know what kernel are you using...
2.6.32.9 or 3.x.x version?
Hi there all, thank you for replies, and here are some extra info;
Fresh facts:
- Kernel: 2.6.32.9-FXP [email protected] #1
- Not overclocked
New observations:
So far I don't see any pattern as to what could possibly be the reason for this issue.
The last time I faced with this, the phone was fully charged and on 2G mode I left it on my desk (my wi-fi router was located next to it, keep it in mind so that it might be a clue coinciding with the BetterBattery logs I will reveal next) and after 3 hours, when I went to check if there were any calls, nearly 30% was drained. Comparing with the initial drain issue (which is a 60'ish% drain overnight) I can say it's the same issue within a proportionate period.
Well takin' a quick look at the BetterBatteryStatus report, drain was mainly caused by some wake thingy called "rx_wake". I don't really know much about all these wake calls in Android system but I googled it and reached to a brief conclusion that it's somehow related with Wi-fi connection. So I'm suspicious that maybe my Android system is perpetually sending wake calls related to a Wi-fi signal even when the Wi-fi mode is off on my phone (only relation I could make here is that I left the phone next to my wi-fi router)
I attach the screenshot and BetterBatteryStatus logs to this post, thanks in advance for your further comments.
Further comments, anyone?
Post the logs in BBS thread. There people has more knowledge and they can help you.
Issue Solved on Galaxy S - Will fit all I assume
Hi
I face the same issue from the day I install the ROM (CM 10.1.2)
I browse the Internet and found the issue
The issue is Wi-Fi and mobile network location
When it is on in this version it turn on the Wi-Fi not only on GPS request and No GPS status
You need to shout it down and issue solved
To change this setting:
System Settings -> Location access and disable the "Wi-Fi mobile network location"

strange behaviour with the battery

Hello there,
I have a concern with my honor 7 (PLKL01B380) which his battery empties at high speed.
My system never comes in deep sleep. I lose almost 10% overnight. Since I disabled the update on the lock screen magazine, I've gained a little bit of autonomy.
What I do not understand is that the wifi reports that it is still active as I always cut the night. For information about the wifi, the relationship between the following two screen shots is strange. I do not know where to look for a solution. I did the update to the B380, I turn off wifi and sync during the night but still nothing. I have two sim cards, I know it consumes more but is that why consumption is continuous all night?
Thank you for your ideas.

Have u tried backup, factory reset and restore?
Hello,
Off course, i thinking about full reset but I don't like this idea because I don't want to lose time on reinstall my apps, organize in groups, reinstall all accounts and passwords .. etc.
I've searched in all parameters and I think i've found the two parameters causing trouble
1. As I say in first message, magazine unlock auto-update, set it to disabled
2. In localisation parameter / advanced parameters / Localisation Data / Extended menu (below) / Search parameters / Wifi Search, set it disabled -> this one make my wifi always on
Now, it looks better, phone going in standby, and wifi not always marked as activated in the graphical view of battery.
I'll see next night if it go to deep sleep :good:
Thanks
Well in my opinion it's better to waste a lot of time re-setting-up your phone than having a huge battery drain, but try a night more, it could be the solution you're on to:fingers-crossed:
I had battery drain problem too. I solved it just by switching off viber contact sync in viber general settings. It kept my phone awake with screen off, and my battery life was horrible. Let me know if it helps.
