Default S3 Battery Drain Thread - 1) False Cell Standby report 2) Standby Drain

Hi,

I have read many battery drain issues on this forum and many other forums, I have also contacted Samsung directly regarding the issue. The battery life is good when I'm using the phone, the problem occurs everytime the phone is in standby mode.

I realise that there are two separate issues going on here;

1) The falsely reported cell standby figure, which is not related to the actual battery drain, only the report percentage used for cell standby. This is important because the false report makes it incredibly difficult to pinpoint the cause of an actual battery drain issue, such as in 2) below.
For the false cell standby issue SUroot has kindly set up a petition to send to Samsung in the sticky section of this forum. Please see a fuller explanation and sign here; Cell Standby issue - please sign "petition" for Samsung

2) An actual battery drain whilst in standby mode. I understand this issue does not effect everybody, but it does affect a lot of people.

I have been testing my battery drain each night and the average drop is 6.21% per hour, so 50% drain over the course of an 8 hour period. This is with the phone on my bedside cabinet, whilst in a strong signal area and not using the phone what so ever. So when I am out and about and the signal is rising and falling the drop is even higher.

I know I can turn off features such as data, GPS, Sync, but this is not practical to do every time I put the phone in my pocket. I am only syncing my gmail calender and contacts, nothing else.

When I contacted Samsung regarding the issue, they advised me on optimsed settings, which did not resolve the issue, they followed that up by sending me the following information;

"Dear John,

Thank you for contacting Samsung and I have pleasure in providing the following assistance.


We are sorry about the issue you are experiencing with your Samsung Galaxy S III handset.

We are aware of this issue that is affecting some handsets within the UK. We are currently developing a fix for this issue and we will be rolling it out via a firmware update in due course.
We apologise for any inconvenience that this may have caused.

If you require any further assistance, please contact Samsung again and we will be more than happy to help.


Kind regards,

Online Support Team
SAMSUNG Customer Support Centre"


So there is a fix coming, I hope. This information was received on the 3rd of August and there has not been a fix as yet. Possibly/hopefully it will come with the predicted imminent arrival of Jelly Bean.

I have been offered advice by some helpful members of this forum and advised to download BetterBatteryStats and cpu spy. I am going to do this and will keep this thread updated and ask for advice on the findings.

With the kind help of the members of this forum, I am determined to get to the bottom of this issue.

John

Christ almighty...no joke...if i take my phone off the charger at 100%...and leave it on my desk and don't touch it...i can come back 3 hours later and be at like 98% this phone has spectacular standby time if running properly...

once the screen turns on however...all bets are off

You can download a free XDA version of BBS (BetterBatteryStats) - [APP] [04 Aug - V1.9.2.1] BetterBatteryStats adds battery history back to Android - xda-developers - in the second post; must be registered. Get the first one, not the others - they are beta I believe, and they crash on my S3 when installed.

Check to see if you have a process called Factory Test, or Factory Mode. When BBS is installed, check to see what percentage it is showing.

I downloaded WatchDog Lite app to check what was going on, and it alerted me that Factory Test was using over 45% CPU constantly overnight. My S3 went from 100% to about 66% overnight without ever touching it.

Try that!

I have had the same issue with battery drain in standby (I'm a US user). I'm assuming it is not the false standby issue as the phone promptly cut off when the battery reached 1%. I've used BetterBatteryLife and couldn't really pinpoint anything other than something was keeping the phone awake even when I wasn't using it.

I have tweaked everything, but the only thing that seems to solve the issue is installing JuiceDefender. This has dramatically improved my battery life. I'd rather not have to use it, but I really haven't noticed any impairment in the phone's performance because of this app. One thing I did learn from JuiceDefender was that my phone was attempting to autosync every 4-7 minutes. Interestingly, turning auto-sync off didn't really seem to solve the battery drain issue the way having JD running did.

I love the S3, so glad I traded in my iPhone 4. However (and this may be an Android issue, not just a Samsung issue), there is something not right with the battery management. Again, I'm guessing there is some process that is preventing the phone from going into deep sleep or is constantly waking it up. Hopefully they will release a firmware update soon to apply a permanent fix. In the meantime, I highly recommend JuiceDefender (free in the Play store). My battery drain has dropped from near 10% an hour to 2% (auto-sync off, GPS and Wifi on).

One other thought (and I'm not a tech expert enough to know if this makes any sense), but I live in an area with 4G but no LTE. I wondering if the phone is constantly searching for an LTE connection it's never going to find and that's what's draining the battery in standby.

Have you ever tried the system panel app? I do have a Factory Mode app running but according to system panel, the app is only reporting a 0% average cpu consumption.
Was wondering if Watchdog and System panel reports different results.

Thanks for all the help and replies.
I have been away for the weekend so haven't done anything more on this, as I think to be a fair test the phone needs to be in the same place, with same signal strength etc.
Now I'm back, I have just downloaded cpu spy and betterbatterystats, so I will leave my phone in the same place on my bedside cabinet, with all the same settings as previously reported and will post up the findings of those two apps tomorrow.

I will definitely need help with the results though as I have just looked through the programs and even if there is something glaringly obvious thats causing the drain, all the statistics look so complicated I doubt I will understand them properly

Default Display brightness

Set your display brightness manually and switch off automatic adjustment (untick from drop down menu)...improved my battery life significantly. Automatic brightness keeps analyzing room light condition all the time draining battery life

The problem is not whilst using the phone though, the battery life is good whilst its in use, the problem is the drain whilst its in standby mode when the screen is off.

I will post up the results from cpuspy and betterbatterystats in the morning.
Which section of better battery stats do I need to pay most attention to? There's other, kernel wakelock, partial wakelocks, alarms, network, cpu states & process, I will post up the screen shots in the morning and hopefully somebody can make sense of them. Which screen shots of which section above, should I take?

Morning all

So I did the same again last night, fully charged by battery, then unplugged it and left it all night without touching it. In a 10 hour period it drained from 100% to 33%, so a 6.7% drop per hour without being used at all.

Here is the screen shot, showing that there was no screen usage what so ever.






As previously said, I used cpuspy and betterbatterystats this time to hopefully find a culprit for the excessive standby drain. I took lots of screenshots of all the information, but I'm not quite sure which section of betterbatterystats is relevant, so I will post up those that I think are, but if anyone needs another section of batterystats to analyse then please let me know.

Section: Other. (Seems from the 10 hour period it was awake for 9 hours 50 minutes and only in deep sleep for 10 mins.)






Kernel Wakelock: (I seem to have accidentally scrolled down the screen slightly and cut off the heading to the top stat whilst taking the screenshot, this heading was called "suspend_backoff"





Partial Wakelock: K9 mail seems to be causing most partial wakelocks, I only have three email addresses though so not sure what the reason would be for this, perhaps to do with settings? Wouls this be draining the battery to the excess of 6.7% per hour?





The sections called 'Alarms' and 'Network' showed nothing.



CPU States:







Process: Again, large amount used by K9 mail





So there it is, the finger seems to be pointing to K9 mail, although I just dont no if it would cause a 6.7% per hour drain? Im also not sure what the difference is between the blue and red bars.
If any of the experienced members on this site are able to look over the results for me and offer me any help and advice as to if/whether any of the above information would be causing the excessive standby drain I would be very very grateful.

Many thanks, John

alarms should not be much issue since your alarm manager wakelock is meagre. network would have helped since multipdp is associated to network use. i googled suspend_backoff and one of the possible culprits could be wifi triggering the phone awake and asleep frequently. if your phone is not in wifi range, the phone will keep searching for a signal thus sucking up alot of juice, try to turn off wifi when not in range.

regarding k9, i don't use it so i dunno how it works. if the settings allow it, set it to sync less frequently eg. hourly. or turn off auto sync altogether and sync only when u need it. for me i use an app called tasker to help me turn on and off auto sync periodically to save battery.

my s3's battery drain is 11% over 10 hours

Hi thanks for your reply. As I said above, alarms and network had nothing to show, but here they are anyway if they are any use;

I should have said, Wifi was turned off.

Thanks, I will check it now how often it is syncing, also have a look at tasker, I wont turn auto sync off altogether though as I need my business emails to come through, I will forget if I have to check manually.

I can only dream of such low figures at the moment, but at least hearing peoples lower standby figures makes me know it is possible on gs3

Thanks, John

im assuming your phone is not rooted? as you need root to access network and alarms. its turned off by default, so if your phone is rooted, turn them on in the settings

Oh I see, no my phone is not routed, so that explains why they are blank .

I have just checked my K9 settings and all three of the accounts are imap accounts so the emails are pushed to my phone, rather than syncing periodically with the server. My poll frequency is set to 'Never'.
I read here that push email shouldn't use much battery k9 Email check frequency settings help
With that in mind this drain issue is really baffling me, from the results do you think its still emails that are the issue or is there anything else that stands out?
I could try removing all my emails this evening and try the test again.

from the looks of it, the main culprit seems to be k9 mail. did it set it to sync all mail from the beginning of time, maybe thats why its taking so long and probably alot of data. maybe just set it to 10/20 days or something.

Ah ha, yes. All three of the accounts were set to sync messages from; Anytime - No limit.
I have now just changed that to 1 week so be interesting to see if that makes a difference. Will post up the results again tomorrow morning.
Thanks for your help.

Hmm I'm finding this thread very interesting. Had an s3 since June and it has been brilliant. I don't really hammer it often so an average day is reading emails, a little surfing and the odd text MSG. With that in mind, I easily get at least 48 hours from a charge. I do have wifi, gps and Bluetooth turned off permanently but have sync and mobile data on.

In the last 2 days I have been getting the problem the OP has. Battery drains within a day with no use, somewhere around 8% an hour in standby. Battery usage shows this to be Cell Standby.

As far as I can work out I haven't changed anything. My apps have been updated and i have installed a couple of new apps but deleted those (adobe air and sky sports centre) with no luck. The only app I can definetly recall has updated was light flow lite but turning that off completely does nothing to improve it.

Running android version 4.0.4 at the moment in the uk. I don't have K9 mail installed (I think?) and have made no changes to how my email clients work. Very frustrated with this. I turned the phone onto airplane mode and it went back to normal, I turned off the sync option on the drop down menu and it still drained quickly so seems to be something to do with the signal perhaps?

Been loving using my s3, want it back to how it was!

Ok, I did the same again last night and it has still drained. Has anyone any more ideas what the drain could be caused by? Please help, I'm completely at an end with this lol.

Well seems as all the fingers are pointing towards K9 mail, I have got rid of that and have downloaded maildroid instead so will test that out tonight and see if the drain has improved at all.

If anyone can think of any other possible reasons from looking at the BBS screen shots, please let me know.

the high cell standby seems to be a misreporting problem with the software which falsely reports excessively high battery usage during standby. try to use betterbatterystats and see which apps are misbehaving and keeping your phone up

I went through this with my s3 a few weeks ago, even with Wifi and mobile data turned off I was losing 40% battery at night. Do you have chrome installed? There is a bug in that which drains battery, you can fix it by going to chrome settings/developer options and turning off tilt to scroll. I also used better battery stats and found out that a lot of my Wakelocks in standby were to do with mobile data, something to do with a system that Vodafone doesn't support so the phone is constantly requesting something from the network. Try turning off mobile data and see if that's the problem. Once I fixed chrome and turn off mobile data when the screen is off then I get 3% drain overnight!

Hi, thanks for the reply, have you read the whole of the OP, and the rest of the thread though? I am aware of the false report and I have posted lots of screenshots from BBS.

Hi scrabbley, thanks for the information. I had read about chrome problems but I dont and have never have chrome installed. My screenshots of BBS seem to point towards K9 but im not sure if it could be something else? I already have tilt to scroll etc and all motion controls and haptic feedback turned off all the time.

Regarding the data, its interesting you say that its something vodafone didn't support, I am on three network so I wonder if that's an issue.

Although I don't want to turn mobile data off to overcome the problem because although turning it off would not be a problem overnight, I am only using the overnight test as an example because its easier to diagnose when the phone is in the same place unused, where I no it has a constant strong signal.
The battery drains every time its in standby mode, including throughout the day so I cant really turn data off it would defeat the object for me of having a smart phone like the GS3.

Hi wolflet27, did you say that in response to me talking about k9 mail? If so there is a "secril_fd-interface" on the kernel wakelock in BBS.
Although its down the list a bit and doesn't appear like a main culprit, maybe you wouldn't mind having a look at the screenshots on posts #14 & #22 please and see what you think?

To be honest all these codes and numbers etc etc are getting on my nerves , I have no idea what they mean and when I google them, nobody else seems to no either.

Not sure what to try next to fix it though

I think I've fixed my problem. When i was turning the screen on from standby I kept noticing the 3G/H icon in use - now I only have 2 sync accounts, gmail and the inbuilt exchange which is linked to my hotmail.

Browsing through the data usage graph, I realised that the exchange service was using approx 600k-1mb per day in data. Except for the last 3 days in which it has used 12mb, 15mb and 19mb. Constant drip of data coming in = battery drain.

Disabled sync for that one account, went out for an hour and the battery dropped only 1%. Now to try and work out WHY it's doing this. I've not changed any options, its set to 3 days worth of synced emails only, push email and nothing I can see would explain why it is burning through 20x the data it should each day.

Well, I've deleted my hotmail account and set up a new one using the exchange again.

So far, it seems to be behaving again. Very odd!

Yep, thanks, couldn't remember what it was called. After I fixed Chrome the suspend_backoff wakelock all but disappeared and the secril_fd was at the top of the list so I looked it up and fast dormancy seems to be the problem.

The data thing is the fast dormancy mentioned above, it is probably what is causing the secril_fd wakelock. Your others, I'm not sure if it isn't caused by Chrome, perhaps you have another app that is monitoring motion sensors like Chrome was?

Unfortunately, the only way to disable fast dormancy on the s3 is thru rooting

Ok, further to the previous BBS results in post #14 & #22 seemingly pointing the finger towards K9 mail, I got rid of k9 yesterday and installed maildroid instead. Here are the results, with no screen time what so ever.

Still a terrible drain of 6.05% per hour.

Somebody pleeeease help lol

@ OP....Yup same problem here all over again with my phone dropping upwards of 50-60% while just sitting on my night stand overnight. This happen on my 1st unit a few weeks ago, and then out of nowhere 4 nights ago started with my replacement unit. I went through that BS with Better Battery Stats and dealing with all this nonsense with wakelocks, and codes, etc. I've honestly had it! I've had countless countless phones over the last several years between Blackberry, iPhones, l and Android phones and honestly have never ever had to deal with something like this. And if I hear one more person saying its just a false reporting thing I'm going to loose it....its real, its not a reporting issue, its a real life bug and Samsung ain't doing jack about it. I'm not rooted, nor am I rooting, I just want my phone back to normal and not have to wake up to a completely dead phone. Does anyone have a fix for this??

If there is no fix in sight, then I guess the best fix is a hard reset and to stick this thing on eBay and get rid of it. Shame because other then this issue, the phone is awesome.

I agree with you Metfanant that it is most likely the software I would just love to find out what, but I will be the first to admit I do not have the knowledge to find what the issue is that's why I'm asking for help.
I have previously bought phones and just used them, so I no my way around a smartphone but not enough about the in's and out's to be able to diagnose a problem like this so your help is much appreciated.

My carrier is 3. (Three UK). Yes I bought my phone direct from them, and it is branded with their logo on startup and locked to their network.

I was aware of a Chrome issue from reading other threads and from my conversation with another member in post #29, but I have not got Chrome installed.

I have looked up multipdp and secril_fd-interface/fast dormancy and found the descriptions you describe, but other than the information on BBS I'm not sure what else I can do to find more detailed information about the specific cause. Without that information I just cant see how I can fix it, I seem to be going around in circles. If what Samsung told me is correct in post #1, I could be waiting months for them to release a fix, then even longer for my carrier to pass it or do whatever they do to it

Have you any ideas on what else I could try?

You seem to have different things causing your phone to stay awake in standby. Tonight you could try turning off wifi and mobile data and sync, to see if there is a problem with apps using sensors on the phone rather than data. If the phone is still not going into deep sleep for very long then there is a problem with an apps settings. At least that might narrow down one of the problems. The wakelocks caused by data syncing might be trickier to fix, how about leaving the phone on Wifi overnight and turning off mobile data to see if it is an app syncing problem or a network related problem?

Tried all of that...its as if someone is secretly taking my phone while I'm sleeping and using it for 3 hours straight until it just dies, and then putting it back on my nightstand...lmaoo!

Just reading through again and highlighting what you said about whether my carrier supports fast dormancy.
That sounds interesting, how would I know if Three UK support it or not? I could contact them but I'm sure they would not admit to being the cause of the problem, and I suspect most of their staff in store/on the phone or online helpdesk would have no idea what I'm talking about and just tell me anything.

Is there a definitive way to find out whether or not this is supported?

John was your phone behaving like this from the get go out of the box? And have you tried a hard reset?

I tried the hard reset on my previous S3 and it didn't solve anything whatsoever, curious to see if you've tried that route.

Also my new device that I got a few weeks ago was perfect out of the box, from the 1st night until about 4 nights ago not a single speed bump. Then out of nowhere I started experiencing the same problem as you all over again. My phone is about 3 weeks old and from the get go until now I haven't had one issue like this arise. I also haven't downloaded any new apps? Seems to be a great mystery as to what is causing this.

Hi Sean, yes my phone was like this immediately, I perhaps should have complained to my carrier before the 14day returns thing, but I opted to keep the phone as I really like every other feature and contacted Samsung for help instead.
I have reset it yes and done the test on the phone in a factory state so to speak, and it does still drain excessively.
To me, on my phone, it does seem to be the cell radio that is causing the actual drain, as the only way I can stop it draining is by setting it to flight mode.
I no people say that there is a miscalculation in the cell standby usage stats which is a fair point. But even with my phone restored to factory settings, no apps installed the battery still drains.

Out of interest does yours drain in flight mode?

I haven't tried Airplane mode yet, but I will say that this seems to be a problem that arises only when my phone is off for long periods of time, like 3-5 hours without the screen being on. Initially I thought it may be a wifi issue, so I tried going the evening with wifi completely shut down, same issue. I also tried messing with the settings within wifi, same issue. I'm really thinking its a problem caused by one of these wakelocks, which honestly even though I've owned tons of phones, I'm not to familiar with that side of the tech involving the phone. I'm at the end of my rope because this is a very annoying issue to be dealing with.

you said your phone behaved perfectly out of the box and then a few weeks in it started...i find it very hard to believe in a few weeks you didn't install any apps that could be causing the problem...but you're the expert right?...

go find help somewhere else...im done with you people that refuse to logically look at a situation and just want to pass blame onto someone else...

i apologize to the OP but im done here

OK bud, take care! Either way, no I haven't downloaded any new apps the last few weeks Mr know it all. Your answer to helping the issue within another thread was...

If your phone is draining during the evening hours while your sleeping just plug it in to the charger and forget about it over night. See my man, that's not a solution to fixing the issue, that's masking the problem. You have a wonderful habit of attacking the people posting and not the issue at hand. But either way, no harm done...take care man.

Hi JP,

I joined this forum specifically to comment on this issue.

my S3 used to be great and the phone used to last near enough 2 days and I started having battery drain issues a couple of weeks ago. I assumed it was something to do with the fact that I had dropped it in the bath (phone still worked fine btw) !!

However, my battery usage went from two days to about 1 day. After reading various threads I did two things to my phone yesterday:

1) Set background sync to "Never" in K9 mail under Settings -> Network -> Background Sync.
2) I disabled some services on my phone as described on the following thread. forums.androidcentral.com/verizon-galaxy-s-iii/202816-safe-disbable.html]Safe to Disbable - Android Forums at AndroidCentral.com

From a full charge yesterday evening my phone is now at 77% charge after 12.5 hours with a few phone calls and checking texts etc, but not a huge amount of use. So 23% battery used seems to be a big improvement.

I'm going to keep monitoring the phone to see how it goes but for now I see a definite improvement.

For some reason Three UK are miles behind on updates and we have only had 1 so far. I keep pestering them on the Three blog but so far to no avail. I'm sure battery life and stability has been improved in the newer firmware versions but on Three we just can't access it unless we flash generic firmware (tricky to do if you only own a mac)


One thing to note, do you put your phone in a pouch type case? I bought a Sena ultra slim leather pouch and noticed horrendous awake time and poor battery life. I narrowed it down to the case pinching the volume buttons which for some reason kept the phone awake despite the screen being off. Needless to say the case was returebed
