Therefore I would just like to clarify that they were not made by me and I hope it does not deter anybody from helping me with my issue.


FAO. Moderators
If I may, without intending to disdain your current rules, as rules are rules. I have an idea/suggestion to make as a possible improvement for you to consider:
Rather than just erasing posts entirely, perhaps just delete the offending text and replace by the words - 'Text removed, Inappropriate content' or 'Text removed, content against forum rules' or suchlike.
Then, that way, even if the entire text (not the actual post) is removed, people currently following the thread or new readers can fill in the blanks of what happened, and by whom, without actually being able to read what was said.

from the looks from the bbs, multi_pdp definitely point to network usage by some app. without root, you are not able to access the network pane of bbs. i suggest u trying turning off auto sync overnight and see whether the drain persists. if it doesn't, we start tackling the syncing apps one by one. but i have a nagging feeling its the email app.

Thanks wolflet27, I will do the test as you say with auto sync turned off and see what happens.

What does auto sync actually sync? Will it stop emails coming through or is it just to stop apps from syncing that run in the background?

So i exchanged my phone yesterday, charged it to 100%, still all factory settings, left over night tonight, went from 70% to 15% in 8 hours

I wonder if I can just wipe samsumg software package clean on it and install the android all by itself, as I am about to give up on galaxy S3. love the phone but cannot stand this idle evening battery drain.

John, instead of disabling auto sync, go into accounts and sync and just disable the one email account from syncing at all. If it still drains, disable a different one. If you saw my post on the first page this was the problem I had. I'm now getting 48 hours+ in standby after resetting up my hotmail account.

Try and narrow it down to one thing first, then you can try and fix it.

i think i found my culprit... the LTE network! I always suspected Telus had shitty 4G, Joh,
go into your settings --> more settings --> mobile networks --> Network Mode - and switch to GSM/HSPA (Auto Mode).
Then see how your phone performs from then on. I switched it over last night just to see if I'd see a difference, 2% battery loss in 8 hours of inactivity. I am hoping it lasts, I think this is what must have been causing it. Looking at the battery graph, the drain was usually highest when it was green (ie connected to 4G), meaning spending a lot more battery power maintaining it than needed. 2G/3G variant offers you the same great phone, but with 80% more battery lol.

Thanks for this thread John. I'm having the same issue. I did a factory reset and didnt install any apps to see if that made a difference and it did not. Its something that comes with the phone. Its driving me nuts as my battery life honestly sucks.

Hope someone can find a solution

I just started getting rubbish battery in standby again on Sat night. Last night the phone was at 100%, looked at it this morning and it was at 43%. The only thing I've done to the phone since Friday is install CarHome Ultra, so that must be the problem. Looking at BBS though, I have a number of different wakelocks that I had stopped getting before installing the app; multipdp, battery-monitor, l2_hsic, secril_fd were all much longer than they had been before. My phone also hadn't been in a deep sleep at all. So it looks like that one app is affecting all of these things, apparently it is constantly monitoring the phone's sensors even in the background. So for other people with the battery problem, it could be an app that uses the phone's sensors that isn't quitting properly. Or a setting on the phone which is constantly monitoring sensors.

For the people who have done factory resets and have installed no other apps, then I think it must be a network related problem or you have a dodgy battery. My boyfriend has an S3 and has left the phone settings pretty much on default and he gets excellent standby battery drain, even with twitter/facebook/emails syncing all day.

multipdp is network use, secril_fd is fast dormancy, battery monitor could be bbs itself (known to have higher wakelocks if you're using the widget), l2_hsic some says is caused by the wifi (i personally tried the method recommended but didn't work for me, you can give it a try by going into wifi settings -> advanced (at the bottom) -> set keep wifi on during sleep to never

unfortunately, u cannot know what is using the network in multipdp without root. neither can you disable fast dormancy without root

I know, but these were all lower when I didn't have CarHome Ultra installed. Now I have uninstalled it and my battery is much better and the list of wakelocks has gone back to how it was before. So I'm thinking either this one app can affect all of those wakelocks, or BBS is reporting them wrongly.

I'm going to try it again systematically when I have time and record the BBS output, both with the app installed/not installed and with data on/off.

The only two times I have had terrible battery on this phone have been when apps (Chrome and CarHome Ultra) have been accessing the phone's sensors in the background. So I thought maybe this could be a cause for other people, although not everybody since some haven't installed any apps and others have done factory resets etc.

Hi all, thanks for all of your help so far. I haven't posted for a while but I have been checking up on the thread to try out suggestions. I have tried numerous things and still cannot find the issue. Each time I try something I have to test it overnight, as a fair and comprehensive test, hence the reason this is going on for so long.

In response to some of your posts I will answer them all here, not intentionally short, but just a quick answer to each, just to show that I am reading all posts and trying out your suggestions/advice.

Thanks for this information DrMorph.
1) Trouble is if I set background sync to Never in K9 mail, I do not get any of my emails so this is no good for me, although I did try it and my battery still drained
2) Thanks for this link, I have gone through the list and disabled many of the ones I can but my battery still drains

A good suggestion as I do have my phone in a case, but I have taken it out to test and battery still drains

Yes I suppose this is a possibility, as I haven't yet tried a new battery but I don't particularly want to buy one. I may yet go back to the shop to ask them.

I had the same hunch as you regarding the email app wolflet, but I have literally turned everything off through sync and in apps then force stopped apps, I have deleted apps, done a restore etc etc and it still drains

Thanks for this information SubTerran, my next port of call was actually to seek a replacement, but from your experience and others I have read it doesn't seem to help the matter. I have also reset to factory settings with no joy, Battery still drains

Thanks bigchief, When I go into accounts and sync I only have one account in the that is syncing, which is my gmail account. The other two emails I have are AOL imap accounts are are just installed via K9 mail. Nevertheless I have tried disabling auto-sync, and have completely removed email accounts from the phone with no luck. Battery still drains

SubTerran, thanks for this information, I was all excited when I read this thinking 'This is it!', but unfortunately here in the UK we do not have 4G/LTE as yet so when I go into this part of the menu I do not have the same options as you. I have tried both of the two options I have in there (cant remember what they are off the top of my head) but unfortunately, battery still drains

Thanks anna_p, in a strange way, its nice to know that there are others experiencing the same problems as me. Like you, I have also tries a factory to no avail. Battery still drains

Thanks scrabbley, I think my only option now is to go back to the shop for help/replacement battery/replacement phone. I have been trying so many different things out, I have pages of information I have recorded/written down, I have folders full of screen shots and betterbatterstats, statistics.

I just do not no what else I can try now, has anybody anymore suggestions before I go back to the shop and start the ball rolling for a replacement battery/GS3?

Thanks again, John

hey everyone,
just an update, ever since i turned off my LTE, its been a week now, phone now lasts on avg 2.5-3 days until needing a recharge, which to me is amazing. Since I dont browse all that much on my phone without wifi, loss of 4G had zero impact on how I use my phone.
I am having JuiceDefender Plus running in the background, and Advanced Task Killer set to kill everything but messaging, itself & juice defender every half hr.

hopefully you can all figure out your solutions, Joh, sorry to hear that 4G wasnt your culprit, wonder if its then 3G network as well? But in that case, I dont see any way out of that

Do you have a Live Wallpaper running? Such as Windy Weather or the Animated Weather application? Both Windy Weather and Animated Weather do near constant data dips even though they are told not to. Just a thought. I turned on the CPU monitor on my S3 and found these to be using cycles. They may have been the culprit for me (keeping for deep sleep).

Thanks for your replies Ches111, I don't have a live wallpaper running no, I changed the stock wallpaper for just a picture of a little green android robot thing lol, its not live though. I also changed the lock screen background for just a basic photo in the hope it may help.

I appreciate that, I don't have media server no, as far as I can see anyway, I sometimes have one called 'Media', but that appears to have gone now. I have however already deleted all my photos, music etc.

In the battery section, I have:
Cell standby, Device Idle. Android System and Android OS. (No screen usage as I'm not using it at all during testing)

My exhaustive list of running apps include:
Settings, Software update, Factory mode, MapServiceSamsung, BroadcomMEMsService, Google Services, Maps.


I have obviously been reading other threads in the hope of picking up a vital bit of information and I downloaded an app that somebody mentioned called 'GSam Battery Monitor'.
After a test with this, it gives me the following information;

Phone Radio - 94.9%
Phone 0.2%
Android System - 1.4%
Screen - 2.9%
Kernel - 0.3%
System (*wakelock*) - 0.3%

All that, and the BBS stats, and all the tests I have done, with combinations of various/all apps removed, sync on/off, no emails, case off, upstairs, downstairs, at work, in factory state etc etc etc etc etc (probably hundreds by now lol) seems normal to me, apart from the massive standout of phone radio.

Then when I click on Phone radio within the 'GSam Battery Monitor' app to see more information it says I had (on a scale of 1-5, 5 being high) a 5) signal for 99% of the time, and the other 1% was a 4. So I clearly have a good signal, but the cell radio seems to be the problem?

This goes back a full circle, to the cell radio issue and false reporting, but other than the false reporting is there actually a cell radio issue on some phones?
I guess only Samsung can answer that, and maybe that is the 'fix' they said they were aware of and working on (copy of which can be seen in my original post).


I think I will have to either:
A) Contact the store I purchased from and try a new battery/GS3.
B) Seek a refund.
C) Hold out, and wait indefinitely for a fix from Samsung, Three, a forum member or whoever/wherever the problem lay (If there will ever be a fix, who knows)

I'm still more than happy to try any suggestions people have, but I must admit I am, slowly losing hope .

Thanks, John

*Possible Breakthrough*

Just as I was getting disheartened, I went through all my running applications yesterday trying to find out exactly what they were doing, and I think I have made a breakthrough.
I won't jinx it just yet, by saying its fixed, as it may have been just a lucky night lastnight, but I will continue to test for the next few nights and update with my results.


Anyway last nights battery drain results; With GPS on, Mobile Data on, Power saving on, Sync on, Bluetooth off, Wi-Fi off.

I charged it up, not fully, but took it off charge at 22:55. = 89%
Left it all night without touching it, until 07:55 this morning = 81%

So that's only an 8% drop in 9 hours of standby - 0.89% per hour = Excellent


So what I did:
Firstly, it is the only time I have ran the test without the battery fully charged. This time it was on 89% to begin with.
Secondly, I went systematically through my list of running applications, and force stopped (Couldn't delete as they were pre-installed on the phone) the following Samsung applications;

1) Samsung Apps - This is the Samsung app store, I also removed my account from the phone, so it doesn't exist in 'Accounts & sync'.
2) Samsung Backup - Not too sure, but presumably a backup method that I don't use as stopping it has had no effect on the phone.
3) Samsung cloud data relay - Not too sure, but presumably a cloud storage method that I don't use as stopping it has had no effect on the phone.
4) Samsung Push service - This is to notify you of updates for Samsung Apps installed on your device via the Samsung App Store

That's it, so basically most of the Samsung pre-installed stuff.
S-voice is still working.


The apps I still have constantly running, in the running tab of applications are;

Settings
Software Update
MAPServiceSamsung
BroadcomMEMsService
Google Services

There are a few apps that seem to turn on and off either randomly or when I use certain apps, but appear not to be draining the battery;

Factory Test
Factory Mode
Secphone
MapServiceSamsung
Video Player
Maps
DSMLawmo


As I say, this is not a definite fix, but it does look promising as this is the first time since I bought the phone that my battery hasn't excessively drained when Ive tested it overnight.
I will of course keep testing over the next few nights and keep the thread updated. Fingers crossed it continues to behave.

Thanks to everybody for all your help so far.

Default Resolved!

Ok, a little update a few weeks on from finding the problem.
My battery has been absolutely brilliant, both whilst in use and in standby mode.

It was a combination of the Samsung apps draining a lot of battery, see post #70, and an app called 'APP Lock' which would cause in the region of 101435 wakelocks in a 9 hour sleep period.

My battery drain in standby mode has gone from a terrible drop of;
6-8% per hour (so 54-72% over a nine hour standby period)
To 0.5-0.8% per hour (4.5-7.2% over the same nine hour standby period).

That is a huge difference! Considering all the tests were done in the same place on my bedside cabinet with a strong signal.


I have included some screenshots of my latest full battery cycle below, it shows my very light weekend usage. These were my settings >
I always kept data turned on, I didnt use wi-fi at all, Screen brightness was on auto, sync was always enabled, gps always enabled, power saving always enabled, notifications enabled.
I only have a few widgets running, shazam, assistive light, sound toggle, handcent sms.






Thanks to everybody who helped me, I'm now very happy indeed with my GS3 .
Hopefully others with battery problems can read through this thread and utilise the same advice and methods I have been given and used, to hopefully help diagnose their battery issues too.

Thanks Jeepmaster, I'm well chuffed its fixed

Your right, it gets a well deserved rest at weekends with only very light usage.

It gets a bit of a screen usage beasting during the week though, so it earns its weekend break ha

Thanks for the research and findings John. I'll definitely give them a go. I've noticed that since moving on from ICS to JB (doesn't matter which ROM, i've tried a few) that whenever wifi is turned on, the battery drain is immense.

When i was on ICS, say i got my phone fully charged at 11pm, and left it till morning (say 6-7am) with wifi on, batt will only go down only 5-7% at most. But after moving to JB, it becomes power hungry for some reason. I can't leave it on for long periods, by morning there'll be only 30% or so left. Somehow turning wifi off but with data on the consumption went back as it was with ICS.

i'm just not too happy with this because our data plans are expensive, so best way to save is by wifi. i don't really want to go back to ICS though i don't really notice much of a difference between the 2.

First of all, thanks John for your hard work. You have documented and possibly solved a problem I have been experiencing for a while.

My girlfriend and I have the same phone (S3) and she has a very good idle battery consumption (less than 1%/h) and I have a 6-8%/h drain. We have the same carrier, phone and contract, so that rules out 3G/4G/LTE related issues.

First I notice rebooting the phone a few times a week was necessary. If you don't you end up having all sort of issue (battery drain, signal issue, etc.)

I want to try removing the applications from Samsung but most can't be removed or even stopped (they reboot). How did you do it?

Cheers,

G-

Got it:

How to disable built-in system application on Samsung Galaxy S3?

Go to Settings.
Select Application manager.
Select All tab.
Select the application that you want to disable.
Click on Uninstall updates (if have).
Click on Disable.
Confirm it by select OK.
Thatís all....

Edit: My girlfriend, who has a normal battery drain, never bothered to install a samsung account.

So that's it? Remove the samsung account and you are good. Delete that samsung account ASAP.

Edit: Sry for double post.

Default Even when i put my mob in aeroplane mode, then the drain is very high

I opened the battery stats when i saw that the phone is switched off by the time i woke up after putting my galaxy for a full charge. Can you tell me what these services mean ?

com.sec.android.app.launcher - 26%
BroadcomMEMsService - 3%
avast - 26%
accuweather - 13%
android os - 14 %
mediaserver - 8%

i dont know why the avast etc are are running when i put it in aeroplane mode. I there is another way to put mobile into standby please tell me.

I havent got this problem before. I am facing it from 3 days. I even used it for 2 full days with the same settings.

I am sorry i couldnt post screenshots as the androidauthority needs me to be a user rather than new for me to post pics

It works.

I see a huge improvement. Cell standby consumption was reduced by a factor of at least 4.

I believe deleting the samsung account may resolve this issue by itself since my GF's S3 never suffered from this issue and she didn't create one.

It seems my S3 still remains awake too much but I now got a much more decent drain in standby (1-2%/h)

I am still at 80% today with 52 minutes of screen viewing. 6 hours of standby. I usually would have been around 50%.

Thanks John for the fix.

How does one go about deleting their Samsung account or verify if they made one in the first place?

Well you go into account and sync under settings.

Then you check what you want to sync or remove account.

I'd just like to thank john, as I've been following this thread closely, and I'm impressed at his cool head - I would have lost my rag with the phone ages ago!

I've not had disastrous battery levels - but have disabled the Samsung apps - just in case.

cheers

John P. Thanks so much for all your hard working fixing this. I recently bought my S3 and have been baffled by how much battery it was consuming throughout the day. I spent a good 30 mins reading through this thread. God only knows how many nights you have spent in anticipation for a fix only to be let down again and again. I have disabled as much Samsung trash as I can and hopefully that fixed my issues, which have been identical to yours all the way.

I think everyone who reads this should email the link to Samsung in an effort that they sort their rubbish apps out and fix this issues properly. Or else I'm going to root my phone and install Cyanogenmod when its released.

Thanks a lot John. I too was experiencing atrocious battery life. Tried everything thing possible even bought an extended battery which seemed to last longer but once I really kept a log of things realised it lastee only a smidge longer. I knew then it was some sort of a software fault.. Just disabled all the Samsung sh*t and im going to run my battery down till my phone turns off so I can have a proper reading if this works for me, Which im sure it will! My usual battery after 10 hours at work + 1 hour travel(taking off charge around 8.30am and getting home at 7.30pm) would be around 40% if mildy used and yesterday after some moderate use was around 20!! I'll report my results back tomorrow

Thumbs up Thank you so much!

John, I registered on this forum just to thank you for your patience and your research in getting this problem resolved. This was my issue, and I was starting to lose hope as well, just like you. Such a fantastic phone, and such a major issue... But you solved it. Thank you so much John! All your hard work was greatly appreciated. You're the man!

John,

your awake ratio is almost 90% of the time during the night. You need to find out which app or what exactly is keeping your phone awake during the night. I have deep sleep ratio of 85% to 90% and for 6 7 hours during the night I lose 2% or 3% battery drain. I use GScam battery app and it shows exactly which app or process how many times awakes the device and for how many seconds. Than you switch off this process/App and the battery life will improve. Your deep sleep ratio should be at least 80%.

So does this really work for you guys? I have a Samsung Account and use it on my S3, and have not removed any of the Samsung Apps (I also have the Samsung Store Installed) and none of the Apps has caused me any battery problems.

You are lucky. It was really bugging me. The fix did work. My phone was not in deep sleep. It was related to either the Samsung account, some Samsung apps or both.

My phone is now in deep sleep 80% of the time.

Runtime: 10h27
Deep sleep: 7h45
Awake: 2h32
Screen: 34m
Battery: From 100 to 65%.
Some calls, texts and emails on the phone.

Hello John P. I read all the post because I have the same problems with my battery. I have the last firmwire and I've discovered that in Settings/Data usage/ there is a new option called restrict background data. I'm discharging my bat until tonight and fully recharging until the morning. Tomorrow I'll post the results.

"I had a dog and his name was Bingo". It worked for me. 12 hours with 10 minutes of voice calls, one email sent 11% of battery from 100% to 89%). Restrict background data works. Also 2g network, wifi, bluetooth, gps off. I have also stopped as many programs I could, especially samsung and google apps (those I could stop). What I did also was to enable from Advanced settings "Do not keep activities". So that's it. Hope it will help you too.

Hello all,


I have registered on the forum only to thank John for his really awesome work. I have been experiencing terrible battery life, my phone wouldn't last more than a day of usage, yet I kept seeing people bragging about how they could use their phones for two days on a single charge.

I have followed John's guidelines, and I'll see how the battery performs from now on.

Will keep you posted

I've had battery drain for about 3 weeks now, having had my phone for 3 months. I've tried turning stuff off etc. Nothing helped improve the 10% or or more per hour battery drain. Juice Defender did help. BUT last night I read about turning off Email, Calendar etc auto sync. Then I charged my phone overnight, turned it on at 8am and by 8pm it still had 52% left. So solution for me - manually sync emails etc when I want to (which is how I used to do it on my old Nokia so no big deal).

Wow, such sites are amazing. Here is my timeline of events and final SUCCESS...

Day 1 - purchase S GS3, test it, fully charged, set up gmail and Exchange emails, sync on, wifi on, battery saving off, gps off, screen set to brightest - I was used to enjoying my last phone, not be paranoid about conserving battery hence such options. Phone lasts on standby with some moderate use for nearly 24 hours (coming from iPhone 4 I was impressed).

Day 2 - loading up more apps and setting screen widgets. Installed Skype, Talk-atone, Dropbox, etc (so, some background apps). Turned on bluetooth to sync with my car. Did not pay attention to battery life that day (following my day 1 test and expecting the same, plus I keep my phone plugged during business hours anyway)

Day 3 - loading up more apps. Battery life takes an immediate hit. 2am full charged. Go to sleep, wake up at 8, half of the battery is gone. At noon the batter nearly dead. Less than 12 hours from battery with NO use of the phone at all, mostly standby.

Day 4-10 - testing stuff - turning off wifi, bluetooth, gps - everything shut down. Shutting down Skype, Talk-atone and all background apps. Battery dead from standby alone in 10-12 hours.

Day 11 - logging onto this forum. Trying several suggestions: disabling sync for all but my gmail/google and exchange accounts. Turning off Tilt Scrolling in Chrome (settings - developer tools). Turning ON wifi (suspecting from my research that contrary to my prev. belief LTE sucks up more juice than wifi these days). Phone fully charged at 2am. Wake up and go about my day. At 10.30am the phone has 81% of charge!!! (SUCCESS). So in 8 hours of standby and some minimal use, only 20% discharge. Back to normal, problem fixed (at least for now).

Because I've done a few things at the same time, I cannot tell which one actually fixed it but the suspects are:

- tilt scrolling in Chrome
- disable sync for all but my emails and calendars (which still gets me what I need via push)

I am grateful for this thread. Got me a fix that I needed. Still not sure how though, but will nail it soon I suppose (will start using Chrome again and identify the culprit)

I can definitely see the sense in disabling sync for emails, but is this pointless if you're using WhatsApp for example, as this will always be polling for data? Or other apps that maintain a connection, like Facebook or the yahoo mail app, which doesn't let you disable sync (AFAIK)

Can you give me an idea of what "minimal use" is by your standards ? 20% for 8 hours standby would be a dream come true and I have disabled all the same things you have.

No, I would not disable sync email. After we've fought with Apple and others to finally give us push email, why give up now and forget it? I have disabled dropbox and samsung sync, left all my gmail, exchg mail and whatsup synced up. Push email is a must for me. Now i still get emails but no more drain whatsoever (well, just "regular/acceptable drain")!

I am now 13 hours since full charge and I have 65% left!!! I am back to normal then, expecting full day, maybe 30 hours of standby with "minimal use". OK, so how would I define "minimal": my guess would be 2-4 minutes of screen time per hour. Fair enough? Moderate use would be 10-12 minutes per hour (that's something I did on day one when I was getting myself familiar with the phone - and which also produced 24 hours of standby!).

Hence, with minimal use 30 hours would not be unexpected. 6 extra hours for much less use (basically, I work in the office so not much need to do anything on the phone).

Hope this helps.

My suggestion - try killing sync altogether for one day. See if it helps. Then remove Chrome and check it out too. One of these things did it for me. I was getting drained in 10 hours with no use... Then, start re-enabling things to find the real cause (re-sync one account at a time!)
