My new Galaxy S3 seems to be draining 2-3% per hour on standby, which doesn't seem normal to me. That's 20-30% lost over the course of the day whilst idle -- too much juice lost for my liking.
Most of the drain comes from cell standby. I'm aware of the bug which reports cell standby much higher than in reality, but that shouldn't affect the actual speed of the drain, just the reporting.
I suspect that the drain is because I cut my old SIM card down to a micro SIM, but I'm not sure. The cut isn't exactly perfect, although the phone does read it. From what I have read, all the SIM card does is supply credentials for accessing the mobile network, so it shouldn't affect signal strength, only whether the phone connects to the network. The signal seems to be weaker on the GS3 than on my old phone, but not that bad -- the signal still perfectly usable in most areas and I never actually lose signal altogether unless in a poor reception area. The drain seems excessive even though I don't lose signal most of the time.
Thanks in advance for the help.

If you are having such excessive battery drain, I would recommend (if you want) to root your phone and installer BetterBatteryStats to track down what is draining your phone so excessivly.
Also freezing unwanted apps with Titanium or simply uninstalling them can help.
If you have not done so, in your wireless settings, advanced, keep wi-fi on during sleep, change to Never. This could also help.
I would also take a look at your sync settings. High frequency syncing can cause an increase in battery drain
Hi, thanks for the suggestions.
I have already tried disabling wifi and disabling sync (I do so by default), but the drain is still excessive. It's definitely coming from the mobile connection.
I would like root and use BetterBatteryStats, but I'm a worried about voiding my warranty (I'll be sending the phone to Samsung as a last ditch resort). Is there a simple way to root and unroot without Samsung knowing about it?

You can root your phone, then before you unroot the phone use TriangleAway to reset the binary counter to 0 which will keep your warrenty vaild, then return the phone to stock unrooted.
I had the same drain issue when I first got the phone. Rooted, and went to a custom rom, and custom kernal, getting better battery life than ever.
OK thanks a bunch, I'll try that when I get home and post the results!
Also if anyone could tell me whether my SIM card theory seems plausible or not, could you please let me know?
So I've rooted my phone and installed BetterBatteryStats. How should I go about recording the battery usage? Charge to 100% and leave the phone idle?

Basically... You can use the phone as normal, but what you are looking for is the partial and kernel wakelocks that occur while it is supposed to be asleep. Once you start getting partial wakelocks it will help you track down what is waking the phone up, so you can take corrective actions, to save yourself some battery life.
OK thank you once again, I'll use the phone as normal and post the results at the end of the day.

Thanks for the suggestion, I I'll definitely be doing that eventually.
Though for the moment, I want to make sure that this isn't a hardware (SIM card) problem.
I dont think so, there is no way it should and it wouldnt be able to drain that much anyway
If you wanted to test it yourself you could take out the simcard after a couple hours of sleep and see if its really hot (take it out and check quickly because it'd loose heat fast due to materials etc) because the power would need to go somewhere & if its a problem with the SIM card then it'll be diverted to the card and it would be dispersed via heat

OK thank you for the suggestion, I'll give it a shot.
If someone could look at me kernel wakelock and partial wakelock stats and see if there's anything unusual, that would be great.
I decided to do a little bit of research, and it seems that much of the battery drain is wifi related (wlan_rx_wake and wlan_wake), but there may also be some mobile connectivity issues as well (l2_hsic and ConnectivityService).
Is my interpretation correct? What can I do to stop these wakelocks?

Try battery saving kernels and rom like CNA...
Rom: CodeBox 1.4.0 Unofficial
Kernel: Horsepower 3.1 by fuss
If you like my post please hit thanks button...
Can't you disable that somewhere in settings? I think they call it Wifi timer
Im not sure though because I never have wifi on - boarding school )':
Sent from my GT-I9305T using xda app-developers app
Well I know that there's an option to disable wifi during sleep, but I discovered that my phone never seems to go to deep sleep in the first place unless I actually turn off wifi and mobile data manually.
I think I've isolated the problem to data connectivity being on. If wifi and mobile data are disabled, the battery drain is normal (basically nothing), but the drain occurs if one of both are enabled. So something is sucking data in the background -- this conclusion also seems to be consistent with my wakelock stats.
I don't know if it's a rogue app -- I disable sync by default, and almost all of the apps installed on this phone are also installed on other devices and I haven't experienced any excessive battery drain on those.

Thank you, I will try it eventually, but I am not sure if my problem is a kernel/ROM issue, and I'm curious to find out what's causing it.
Related
I've read and read, searched and searched this forum and have not come across my exact problem yet...
I know there have been overheating issues, and I know there have been boot looping problems... all causing terrible battery life, mine has neither. Let me rephrase, my overheating issue is not due to me actually using the phone... On idle (with the screen off), my Rezound only lasts about 2 hours on a full battery. Granted, I live in an area where there isn't full service, but there is some service. I can watch as data is being exchanged with no apps running. What the hell is using data? I have a feeling this is what is killing my battery, the phone is not at all sleeping. I have deselected "always on data" and I turned off fast boot and auto sync.
Any suggestions would be greatly appreciated.
BTW, my phone is a bone stock refurb.
Try a factory reset maybe?
I can do that, but it doesn't really solve the problem. It just started doing this yesterday. I've had it over 2 months and haven't downloaded anything different. I would really rather just figure out what is causing it, so I don't have to do a factory reset every time something like this happens. You know? Thanks for your suggestion, I'm afraid that is going to be my last resort right before exchanging it...
Try exchanging the battery first. Start small. Work your way up to the big stuff(exchanging the phone). Why give up the customizations you've done if you just have a bad battery?
I was thinking it may be a bad battery, but it concerns me that I can watch the data stay running even though I'm not using anything that requires it. My brother has a Rezound and I placed mine next to his and literally watched the battery life deplete 10% in 5 minutes while his lost no percentage at all, both were idle with the same screen settings. Is it common for a battery to fail that drastically out of nowhere?

If data is constantly being used, something HAS to be using your data. I'd get an app like better battery stats and CPU spy. CPU will show you if your phone is going into sleep mode at all and better battery stats can show you which apps may be causing it.
Do you have the 4G antenna on?
I have betterbatterystats, it shows android system at the top of processes. That program is a little difficult to understand since everything is abbreviated.
I appreciate all of your responses. I just got off the phone with Verizon, they're sending me another phone AND battery for good measure. During lunch today I watched the percentage of my battery deplete while it was plugged into the wall and not being used, used a different charger, nothing. It wasn't even hot. I turned the phone off to try to get it to charge. when I turned it back on, it got to the lockscreen and then restarted itself. Boot looping now. I'm not going to fool with it anymore. Maybe the third Rezound will be better.

I haven't changed anything from out of the box other than visual properties. I'm assuming the network has a little to do with it, but it started failing way too fast to be a radio problem IMO.
I received my 2nd Rezound last week. First one had the hiss/feedback/interference issue through the headphone jack that escalated to a level of to not being able to use the headphones at all without being painful. Anyway, the new one is running very hot (battery) and is draining the battery almost as fast as you're describing yours to do. I've used both the standard battery and extended. This morning while using it at home on wifi with most of my syncs either disabled or set at a min of 2 hrs it drained my extended battery by 20% in 20 mins. I wasn't even using the internet or streaming any music or video. I was working on setting up calender and task list widgets. Phone is stock, not rooted. I will be calling Verizon tonight to see about getting a 3rd one. Sucks as I really like this phone when it's working properly. If the 3rd one has issues to and HTC isn't rolling out any fixes for them I might have to look at something else. But I don't want to!
I feel like if I can get the hardware to cooperate with me, I can get the software to. I was planning on rooting after the ICS push, but the phone obviously had different plans.
Set your phone to CDMA only, especially if you don't live in an area with LTE coverage. You will see significant battery advantages from that alone.

I should have mentioned that I'd already done that (only 3G here anyway). I've done all the battery management tricks I've read about but this phone has an issue. I'm not even getting half the battery life out of it that I was on the 1st one. And the battery gets significantly hotter then the other phone.
tried wiping battery stats after 100% and drained/recharged a few times?

I know this question has been asked really lots of times, but I didn't seem to find cases similar to mine.
there doesn't seem to be any wakelock (except 2 which is incredibly short) and it was in deep sleep mode all the time. but yet, it drains almost 5% per hour which i find is really too much...
I've tried lots of firmware (litening, wamanlite, turkbey, stock, ICS) and removed all the unnecessary bloatware to reduce wakelocks to a state as shown in attachment. but still, they do not have any results, still get less than 1 day life without any usage at all...
Could this be hardware problem? I find it gets hot really fast even when i'm just facebooking.
Or is there anything else can i try to do? this device really started to disappoint me ever since the battery life looks like this.
any help will be greatly appreciated.

Try Hydrogen-ICS latest version, it seems to be "the rom" today
Battery life is very good and its overall a stable system.
Make sure to "Fix Permission" after first start, reboot recovery and do it.
Also sometimes "to much junk" in your SD card can cause battery drain, copy your files and format the SD card, you might see some diffrence. (i did)

you got 20Hrs out of your phone? grats! as of lately i've been trying alot of different roms and different customization settings from kernel tweeks to CPU tweeks (undervolting/underclocking) and im even turning off every extra setting that consumes battery power apart from wifi
on best with a 2000Mah battery i get 13 hrs on standby and 4 hrs if im playing a game - these days my phone doesnt charge anymore - it discharges even when plugged in
I recommend downloading HydrogenICS, it's good! Download Battery drain, so you can see how fast your battery is being drained.. Also, let your battery go down to 5% then charge your phone
Something is seriously wrong - you've hardly used it, looking at those graphs.
I'd try a stock anything, and if you get similar drainage send it in for repair/buy a new battery.
this is'nt normal , in sleep mode i can get 20 hours and only lose 9%
use hydrogen and neak , and try , if you get the same result so it will be hardware fault
the 3g data it kills the batt very fast,i don think u got a hardware prblm,cause 20hrs an still to go is good ive seen ppl reporting worse...dude instal better batt stat,3g watch dog but remember batt saver apps too run in bckgrnd so i suggest u stay on a stable rom wiv a custum kernel like siyah or neak an watch the batt in better batt stat.....wen i need more juice i switch to airplane mode in nite then rebot in the morning....i don hav any tweaks or uv,oc but ive seen the batt is very good wen i don use the data or wifi or download or update,pm me if any doubt......cheeeerz
You flashed different ROMs the last days? First thing is you should only flash with full battery and after flashing it needs some time (three full battery cycles e.g.) untill the battery works fine for the ROM.
And you may recallibrate your battery. Turn the mobile off and load the battery to full. Then go to CWM and reset your batterystats. Now unload till the mobile goes of and reload to full with mobile off. If you doe this for e.g. 3 times the battery should be recalibrated.
I must say Omegas ICS + Speedmod or Siyahs Kernel. Best ever. Or checkout Paradoxxxs rom very stable but for me not so good xD

bro, 20 hours is with 99% deep sleep is seriously wrong. better battery stats cant tell me nothing, since i have no wakelocks or whatever, and all those battery savers apps, they spent more battery than they can save. when those screenshot is taken, i can tell you for sure, bluetooth, gps, 3g, wifi, auto sync etc everything was turned off. even brightness is 10% (which is even lower than auto brightness settings). anyway thanks for the reply

nope, i always try at least 5-6 battery cycles after flashing to see the real graph. and i've read in this forum somewhere, calibrating battery by deleting batterystats is useless for this phone.

thanks for all the replies and recommendation, will try different rom & update again (probably in 4-5 days for trying 2 roms
I have exactly same problem. On GB over night(7 hours), battery consumption was around 9%. On ICS more than 20%, but nobody touch phone. I try few roms: wanamlite, omega, bezke, pure. Now i have hydrogen. Better battery stats shows nothing special. Only thing what i can think is wi-fi. if i turn off seams to be better, not that dramatic, but anyway not that good like on GB.
strange...
let me ask this... what does the yellow color in the phone signal mean? anybody got any clue?
shouldn't it be green/gray ?
in my phone whenever i have green/gray in the battery view the bar hardly goes down on idle but i see a big drain compared to green/gray when it becomes yellow even in idle
let me post a pic to clarify...
i was complaining about sudden batt drop on cm9 ics, i know its 2 diff roms but still the yellow bar got my attention in both pics...
just searched google and came up with red= no signal, yellow=very bad signal to no signal, green = good signal/full
bad signal makes the phone look for the signal in a bad way using a lot of the battery...
guess i found out why my batt suddenly dropped so bad compared to the rest of the bar...
id suggest flashing a couple of modems and testing how good of a signal u get with each and sticking with the one that works for u, if its a weak signal from the provider then find a better provider that covers ur place with better reception...
start from there and then if batt life is still bad search search and search... best of luck with ur phone...
@mazroui
in those 7 hours your phone should lost 9 - 10% of battery, but not more than 20 unused, what is process causing that usage?
for me: i charged phone before sleep, when wake up after 7h i had 20% left.
Android OS - 92% , rest for cell standby, phone idle and screen. Wi-fi was setup to sleep when screen is off. Better batery stats show that wi-fi was on for almost whole time
Cell Standby and Phone Idle using that much of your power means that the signal in your area is horrible and the phone is struggling to maintain a decent connection with the towers, this can drain a tremendous amount of battery depending on how bad the signal really is, the yellow bar means it's not optimal but there is a large degree of variation between the top end and bottom end of the yellow bar spectrum. Try a different modem or move your phone to an area with better reception and see if you still get this sort of drain.
Android OS is misreported by practically every Kernel because for some reason Samsung accidentally made Screen On add to the Android OS bar, so your Android OS usage is actually AOS + Screen On, for the most part high AOS usage can be ignored as a source of drain using the phone info battery screen, I would look elsewhere for the problem. Sometimes rogue apps hide their wake locks in another wake lock, for instance if you have facebook or many of the IM programs on your system, they poll their servers a lot causing a kernel wake lock called 'svnet dormancy' (in gb) or 'multipdp' (in ics) this causes a lock of 5s to ensure proper packet transfer, if your app is requesting packets every 4 seconds, then its essentially a permanent wake lock but may not be reported as the app being the source.

There is a defect with Android where good signal strength is mis-reported on this screen as yellow, even if you have 100% signal.
Until you go to About Phone > Status, just once. Then when you go back to this screen, it will start reporting as green if you have good signal.
I've tested this out on my phone, and confirmed it... try it out yourself.
I stopped caring about it, so I just ignore it unless it gets reported as red.

If you look at the graph in the right pic you can see that the curve is less severe when WiFi is active, while this doesn't prove my point that its a network issue it does increase my suspicion that the issue is mobile data related.

Something is horribly wrong with that. Do a full wipe. If it still does that, reflash your firmware. If it STILL does that, maybe flash to a newer stock ICS firmware? Then as a last resort, you may want to go back to GB.

This guy may be onto something, actually. First thing you should try is flashing a different modem. THEN do all the stuff I said above.
EDIT: just noticed you're in Oz. Try flashing a T modem. Most Australian users report much better results with both battery and signal after doing this.
Hi everyone,
I appreciate that there are threads on this already but this is different.
I have created a petition because Samsung support have not acknowledged that there is an issue. There recommendation was to "Factory reset".
It has been identified by members of the forum that the mA in battery stats used to calculate Cell Standby % has been set ridiculously high.
Please see explanation here.
Rooted users can fix this by flashing more realistic values here
I would like everyone who has the issue to sign the petition, so we can send it to Samsung and prove how much we like this fixed.
Link is here:
http://www.ipetitions.com/petition/samsung-galaxy-s3-cell-standby-issue/
Moderators, please do not merge / delete. Could this sticky please?
I wrote this in the other thread but I'll leave it here as well.
Do you guys realize at all how this works?
I mean, cell standby, percent shown means how much is used of the current % usage... If there is 50% percent of battery used, and 30% by cell standby, that means that 30% out of that 50% in total was used by cell standby, not that cell standby used 30% of battery, are you even aware of that?
If your phone's screen is off most of time, it is normal that the cell standby will be high in this list then. That doesn't mean it drains your battery it just shows how much of used battery was used for cell standby...

Yeah makes perfect sense. Also goes to show how efficient the screen is compared to other phones including the sgs2. I think the sluggish touch wiz with all the screen redrawing is more of an issue.

Yes we are aware of how it works. Its simple maths.
The issue is as many of us see it, even with screen on times of 2 hours +, the cell standby is massively high and sometimes more than screen on time. This is NOT right!
Turn off wifi and data and battery loses 1% every hour or 2. With wifi & or data on the phone loses about 2-3% every hour.
The reception radio isn't the problem.
Most likely some background syncing happening. I've turned all types of background syncing but drain persists.
Could just be that having wifi or data on chews up battery, ie hardware.

Thank you captain obvious
It's the fact that cell standby often tops the battery usage list even when the screen has been on for like 2.5 hours. It was never this high in the S2 or other Android phones.
Somebody suggested it could be a change in the way cell standby is reported, which is a possibility, but it would be helpful if Samsung would confirm or deny that.

Precisely.
In my email to them, I asked them to confirm if it was reporting.

I see. Yeah, sorry for being obvious then, I just had a feel that some folks don't get it and wanted to explain it. I don't have battery drain issue. But I don't have wifi and 3g on all the time though.

Do you have a static IP set up on your network at home?
Something I just realised is that my battery reported "Wi-Fi" usage when I was using DHCP, but it doesn't report Wi-Fi now that I have a static IP set up.
I'm going to change it back to use DHCP and see if that makes a difference. It could be that Wi-Fi is being reported under cell standby usage for some reason.
Although... that doesn't explain why cell standby is so high while I'm at work and not connected to Wi-Fi!

Sorry, your "do you guys know at all how this works?" comment came across as a little condescending but you probably didn't mean it to be
The issue is basically that cell standby is using a lot more on this phone than on any others, but it could be a reporting issue. We're trying to figure out what's causing it.

Yes after your thread on AF, I set it to Static. You reported that initially was "wlan_rx_wake" under android OS.
I wasnt experiencing high Android OS usage, but I did it anyway. It hasn't affected cell standby.
I cannot recall if WiFi was reported separately in the battery report page before Static but it definitely isnt there now.
I have tasker turn off my WiFi and I spend all day at work with wiFi off (But data still on) and I still have the issue.
It is slightly better than it was after changing modems and roms, but its still high.

I may be mistaken about WiFi being reported separately, just seemed to recall it was I just went back to DHCP and it didn't make a difference.
But yes... I seem to get high cell standby with or without WiFi on. Having a bad signal doesn't seem to have as much of an impact as it used to, as cell standby is so high anyway.
Although it does appear to be a simple reporting issue, we should still show how much we want this fixed.
Only 46 signatures. Please sign if you would like realistic consumption information in the battery stats page.
To let you know, I have re-reported this issue to Samsung, including the 150+ signatures received so far
I doubt that this is simply a calculation and displaying issue.
By loosing 2-3% charge every hour the battery should be depleted in about 35 hours without doing anything else. Let's say the real drain is about 1% per hour. A tenfold displaying error in modem power usage would mean a difference of real 50-60 hours in battery time.
Also yesterday the phone didn't seem to want to go into deep sleep, rather staying at 200MHz most of the time. This was using I9300XXALE8. Today I installed I9300XXALF6 OTA and that issue might be solved. Although I have no long term experiences yet, naturally. But the battery drain seems still to be there.
The attached screenshot shows usage with 17min of screen usage.
Stock rom, no root or anything else.
Here is an update:
Dear Dan

I noticed my S3 drains about 10% battery overnight. I dont think this is normal. Wifi and 3g are off, it just lies there by my bed doing nothing. Ive restarted it and no help.
Cell standby shows 41% usage. Is that right?
The 2 red circles in the screenshot show when my phone is idle just lying there.
Any help?
We need more information. What apps run? have you remove/freeze bloatware. Are you rooted? what rom are you on?
I'm going to run this based on speculation perhaps side effects of rooting your phone? I know there is no conclusive evidence of this but a hypothesis as such. My apologies if you aren't rooted.

why would rooting your phone create battery drain?
OP the standard answer is to install better battery stats and check it again to see what those wakelocks are. Once you find out why your phone is waking up you can do something about it.

I'm also getting a 10% battery drain over night. I've been putting the phone in airplane mode to see if that helps at all but it really doesn't. Anyway we can inprove this? 10% seems like a lot for sleeping...

install better battery stats and find what causes wakelocks......as above post!
Sent from my GT-I9300 using xda premium
thanks for the replies everyone, Im using the latest stock firmware... no rooting here...
Installing better battery stats as we speak and see what they say...
GSam Battery Monitor and / or BetterBatteryStats would be the first place as mentioned already.
I was able to find what was causing me most issues. It was some Calender storage and Google syncs (bookmarks, contacts etc) even though I didn't have them activated.
Anyway, after freezing them I now only lose 2-3% overnight. That is with gmail push, email sync every 4 hours and about 7 or 8 other Widgets updating every few hours. Mostly noticed a massive improvement when I flashed the latest siyah kernal.

I don't know but I get the feeling that rooting various phones might have hidden side effects as such, rooting your phone is still evolving as of today. There are still alot that the general doesn't know hence there are always new things about rooting although I might not be knowledgeable in that department. However is it possible to unroot your phone? rather revert it to stock? try doing that and see if there are any differences.
Hey, I've been using stock 4.1.2+ExperiencedKernel for a long time, it always worked great, but a few days ago I installed an icon pack for KKLauncher, and since then my battery consumption got really bad, around 15-20% per hour when the display is off! I've tried deleting the icon pack, but it's the same, I'm even checking BetterBatteryStats for details, but it doesn't show anything suspicious, although I'm using the app for the first time, so maybe I overlooked something. I have also reflashed the rom+kernel with full wipe, but no luck. Can anyone tell me what can cause this mess, or what should I upload from BetterBatteryStats for someone to check the problem? Thanks in advance.
btw it goes to deep sleep well, so it's not an app that wakes it up constantly (I use greenify too). also the phone itself is very hot, don't know if it's just the battery or the whole thing... but the phone functions correctly.

If you don't have any wakelocks keeping it awake and you've reflashed the ROM, kernel and did a full wipe and the battery drain still exists... Then I'd say your battery is failing, especially if it's getting hot. My L9 never gets hot, even under heavy use.
The only other thing you could really try is flashing back to stock and see if the problem is still there... Really though, I'm pretty sure it's your battery.

Hi, thanks for your answer. The problem is, the phone gets really hot on the upper side of it, near the camera. The battery never gets hot at all. Is it possible, if it's battery problem?

I thought you meant that the battery was getting hot. The last time I had a battery go out, it was getting hot and it was draining fast. Shortly after that it wouldn't take a charge anymore.
It is possible that it's a hardware issue. WiFi, GPS or the camera could cause it to get hot also.
You can also try and boot the phone into "Safe Mode" and run it like that for a day or two and see if the problem still exists. If it problem disappears while in Safe Mode then you have a rogue app or something that's causing the issue.
Then to narrow it down you could try downloading Wakelock Detector and see if something is keeping it awake, making it hot and drain the battery.
Monitor it with Better Battery Stats and Wake lock Detector. Post some screen shots of BBS and Wakelock Detector here too. That way we can see if something is going on.
This is one of those issues that will take a process of elimination to figure out.

I've been using BBS, it shows that the phone is in deep sleep in most of its off time, no app wakes it up. Also, wifi seems to lose its signal very often, even though it's strong (there wasn't any problem with that before).
I'm using the phone now without SD and SIM cards, it doesn't seem to be that hot than it used to, but charging and draining are still very weak. I'm gonna try safe mode as you suggested, and also using the phone without wifi turned on, if that is the issue. Thanks for your tips.
So, the phone cooled down after I turned off wifi, then I rebooted to safe mode, and it became hot once again, but after the media scanning, it cooled down once again. So I guess it may be the CPU? I've been trying to get a picture of the phone's circuit board with no luck, because the phone is only warm in the upper 1/3, the other parts seem to be cooled down all the time.
I'm gonna return it to T-Mobile on Monday, hopefully they won't notice the unlocked bootloader.

Yeah it might be the CPU. Also if it's dropping and/or scanning a lot for WiFi, then it will definitely get hot and kill the battery quickly.
I don't think that T-Mobile will notice that it's unlocked. As long as you flash back to stock ROM before taking it in, then they probably won't notice. They would have to be purposely looking for it to be unlocked.
You might want to flash back to stock anyway and see if the problem is still there... It very well could be a ROM/kernel issue causing the problem.
