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.

No never only time i get battery drain is the usual after flashing a rom .

I'm on build KE3 and in 4 days I have experienced no battery drain. Every time I check battery usage; it's usually 50% display drain.

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,
Sul
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
hello, before all, i know there are too many posts about improving battery life and other, but i wanted to ask my personal case. i have SGSII 2.3.6 v6, based on stock DDKQ8 2.3.6.
The thing is that having wifi, the battery life is almost normal, for a 1360 mAh battery, but with 2G or 3G the battery draining is too big, for example using only whatsapp with 2G, the battery drops so quickly, i have tried all, underclocking the phone, clearing battery stats and all kind of tricks, thank you.
The radio hardware on the phone besides the visor ilumination in one of the thing that most battery consumes!
Even if you have no mobile data on, its always consuming! when you turn that on! the usage of the radio hardware on the phone gets 5X active and thats why the battery drains so fast! if you are on a area that has poor service ... add 1 more to those 5 times!
This phone was not made to endure that "pain"
my phone can last up to 3 days on DDQ8 stocklite v6 ... and i still use it in a normal way! use mobile data! Use wi-fi! etc ...
but ... i always turn both off when not using (3G and Wi-Fi) my visor ilumination is almost at the minimum! have no animation! have no sync on ... its bad? yeeessss
Ace battery SUCK's in wathever ROM you install it ... accept it ... all we can do is minimize the "damage"
You have to choose performance or battery! Both? Nearly impossible
Enjoy your ace!
thank you very much for you advice! i will try to follow it, and then i tell you, but apart from that, i want to see more advice or something, but whatever, thank you

Try the GreenPower app. It can save a lot of juice.
SnowPluralism is right. Check your batt stats and it should say cell radio has a high percentage of your batt drain. Juicedefender (& Greenpower suggested above) is an app that regulates your data, turning it off whenever your screen is off (and turning on for when your phone requests data sync). Not much more can be done.
yeah.. all battery power saver application will only regulate the data communication, gps, screen brightness.
the most energy consume is data communication. as we all know, android also have the background data communication. so eventhough the sync off, it still consume a lot of batery.
turning off the data communication will save a lot of batery.
but, android without data communication? same as blackberry without BIS (blackberry internet service). just a dumb phone
okay guys, as you are saying, im going to focus in regulate data connection, im going to try GreenPower and juicedefender, then i will come back and tell you!
Hi all,
I'm new in this forum so I hope to break no rules in my first post. So first of all: I'm fighting this problem for nearly a year right now, I tried so many things I can't even remember and I really never found a answer in any forum.
I had a Samsung Nexus S which started to have this strange Android OS battery drain some weeks before the OTA ICS came in. I read thousands of forum posts to try tons of stuff to solve the problem without any success.
I then decided three weeks ago that it's obviously time to get a new phone so that I bought the Galaxy SIII (int). Strangely I still have great problems with my battery life which brought me here to ask some pros now.
Phone: Samsung Galaxy SIII (int)
ROM: StockROM (4.1.1) and CM10 Nightly
Carrier: German E-Plus
What is the most noticeable about the battery drain is, that it appears in standby (over night) in both ROMs, Stock and CM10 likewise with some minor differences.
In 10h standby (Wifi on, Bluetooth, GPS, NFC all off, only few widgets, AquaMail on push) battery goes down from 100% to 70%.
After all, I tested both ROMs in the same situation over night and the bettery drain is pretty comparable (see the screenshots).
What I already tried (in both ROMs):
- disable all Google Maps autostarts and disable all location services
- disable apps like Gtalk, G+ etc.
- uninstall AquaMail
without any effect on the standby battery drain...
Any idea about this?
Thank you,
Mika

It can happen if u have a weak network signal. It takes out a whole lot of battery. And with wifi on, I believe that's a decent battery life. And try putting the phone on flight mode during night. Saves a real bunch of juice. And do a cache clean and reboot.

Thanks for the quick reply! About the network signal: in both cases the signal was pretty good. Did you check the screenshots? In both ROMs the NetworkLocationLocator seems to use much battery during night. Is that normal in standby?
What is strange as well is, that after I changed the SIM card into my new phone, did a factory reset on the old one (which I did several times before) and installed some basic stuff with a different google account, it looses some 10% in 24h in standby with Wifi on.
Is there any possibility, the battery life changes significantly with changing the google account because of differences in the contact or calendar app or whatever? Or could be the missing SIM be the huge difference in battery life?
Thanks again
Mika
Disable all sensors gs 3 has loads of them for smart stay front cam needs to be on always which drains battery.. So that should help the case

With wifi on, that's a real good battery life.! A whole day and just 10%. And I don't think battery life has anything to do with the Google account. If u have turned on auto sync, that's gonna consume some battery too as the apps like fb keep running in background.

Hi Lifehacker7,
like I wrote, the 24h and 10% do not concern the Galaxy SIII but my old phone.
Maybe I have to clarify that again: it's not about a general battery life but about the standby power consumption. Maybe someone could have a look at the screenshots. I guess they might be very helpfull!
And again: there are two different ROMs I tried. So it could have nothing to do with the sensors and stuff since the CM10 does not use them at all...
Cheers,
Mika
nice ideas
Anybody who could maybe have a look at the BetterBatteryStats screenshots and say whether there's something conspicuous?
Is for example the deep sleep mode with its 75% in standby normal or should that be less?
Should be the Android OS (in CM10 ROM) or Android System (in StockROM) be the most power consuming process? With my old phone its always the Wifi which is first in list.
Should Google Maps with its three processes, especially the NetworkLocationLocator (see the screenshot of the StockROM) wake up the system so often in the night?
Any ideas?

No, I even turned off the location services completely, without any effect!
I tested both phones, my old and my new one again this night with the same turned on/off (Wifi on, GPS off, auto sync on, ...) both with a SIM card with the same carrier and both with some apps like fb, whatsapp, weather widget. Old one lost 3% in 8h, new one lost 21% in the same time.
No ideas?
You can see a bunch of threads on the google forums already regarding miserable battery life on Android 4.2.x because of LocationServices
Anyways, try this on CM10.x ...disable Location services (GPS + Wireless) ..reboot ... now enable the GPS only ... if it asks that Google will collect data in background, blah blah select Disagree ... reboot
Using Developer Option menu enable onscreen CPU Usage and leave phone on standby ... you will see that Android OS usage will come down drastically (almost stop!)

I tried that in StockROM, and it did not change anything, same battery drain in standby. The NetworkLocationLocator in BetterBatteryStats is not listed under partial Wakelocks anymore. So I think, that's not the problem.
Any idea?

This is the 8 hours after I turned off location services on StockROM. I barely used the phone this 8 hours.
Hi, New to XDA, also new to the S4, currently my battery life is quite bad, I am attaching a couple of screenshots so that you can get a better idea of whats happening with my phone.
Here is a list of items that are on:
GPS
WIFI
Mobile Data
Sync ( Google account only )
Brightness ( Auto )
The problem I have is that I have heard a lot of people say they get 3-4 hours of screen time, as you can see from the image below, I have only had 38 minutes of screen time, one thing I will add is that my screen gets warm when I am using it ( you can feel its warm/hot when you touch it ), is this ok?
Any help will be greatly appreciated.
Thanks!
there have been a lot of reports saying if you are on wifi and idling battery drain is really bad
how bright is your screen set at?
not very good results, I would buy another battery first, no hurt in having a spare, and see if it is doing the same, cause, looks like you have nothing really eating up the battery. Then if that does not work, I would go for a replacement.
Good Luck!
First, are you rooted and/or running a custom ROM? If so, was your battery any better on stock? I'd hate to suggest it, but Verizon would anyway, have you tried a factory reset, and run without apps to see if it's any better? You're right, though, that it doesn't look like much is killing the battery. I'd go for the replacement through Verizon if it doesn't improve.

I had the bad Wifi Idle battery drain..After 2 weeks of trial and error (and reading through tons of Shark Logs) I tracked my issue down to Multicast being enabled on one of my access points.
I recommend the OP log into all of their Access Points/Routers and disable any reference to Multicast...Of course you wont be able to on a school or work network (unless you have the proper authority and about 300 change management endorsements..but I digress).
I have several AP's in my house..little did I know that an old WRT54G (with tomato firmware) had Multicast enabled..it was causing a lot of noise on my LAN and only my S4 and S3 were affected...No other Wifi devices seemed to care..and I wasn't even connected to that Access Point..It is just an old AP I have on for some Legacy devices on my LAN.
Once I disabled Multicast, my Idle battery returned to normal..Then I had the "runaway Google Services" issue that some people have, but then I just disabled all Location services on my phone and that returned to normal.
TLNR - Disable Multicast on you home router and any access points you have on in your LAN.
I think we've ALL been here. Is there any uniform answer to this?
Let's be honest, I'm one of the not so frequent xda user, I always read several articles but have been, so far clueless.
I have the international model running on CM10 and constantly switch between ROMs of stock and CM, I've always liked AOSP ROMs, love the simple and uncluttered interface as opposed to the ever so bloated touchwiz. What else can I say? It has 32GB SD card and 16GB onboard storage, and it has a little trouble with 3rd party chargers (lose connection / disconnects every so often ) Its an old phone in technology time, but its still great.
So, I've tested wirh CM, stock and 2 other kernels which still make me feel like the phone is gobbling up a power plant everyday. One main culprit is Cell Standby which is very odd since it's usually just in my room (I use an other phone otg) and has a pretty decent signal (3-4bars)
On the most recent checks:
Cell Standby - 25%
Android OS- 18%
Screen - 15%
Google Services - 10%
Phone idle - 10%
Android System - 6%
And the rest are some of my apps..
I just recently started using Deep Sleep Battery Saver and wakelock detector. I'll send the info when the results are in for a day.
I'm not that fond of using 3G since data rates in my country are time-based and the KB-based pricing is off the charts. So I only use my phone for call and text and the occasional casual gaming and browsing (usually the cnet app)
I can only say that, if we could help on this either way, there are a ton of xda threads related to fast battery drain with varying issues because of Androids openness, I can only think if there would be some sort of centralized thread for this, or if you guys could help. That would be pretty awesome.
Ask any question or request anything so I could get this phone going. Thanks
Cell standby will be highest because you don't use your phone.
It's not a culprit,it is normal that it is up on the chart
But if you are experiencing any battery drain of more than 1-1.5% on standby then you have to look for an app or similar service running in background otherwise there is no problem
Press thanx if i helped you in anyway...
I don't think so. I left my phone's battery last night at 29% and after waking up 6-7 hours later, I got 16% left.
So that's around 13% consumed in one night without using it, or 2-3% drain per hour.
I already greenified Facebook and Lookout which were the biggest wakelocks, deep sleep gave me no noticeable difference even on Slumberer mode. I'm suspecting this is due to cell standby. the location which my phone was in had 3/4 bars of signal, wifi and location services are also turned off.
What's the big problem here really? I suspected it may be due to facebook but nothing has changed so far
Update: Signal strength is 73-80+ dBm, When I got home today the phone was dead from 16% this morning. The highest consumer is Cell Standby at 26%, Facebook is already turned off and everything, Still no perf difference.
So I also have a friend on and he's got a GS4, battery life was terrible for him since the kitkat update.
Anyone??
