Thank god for this thread. The Samsung apps were my culprit (fingers crossed). I also did a sim swap. Sim swap has helped my signal issues also. The Samsung apps are a major battery drain. Disabling them has helped a whole lot. Thanks to everyone and all of your advise!
God i love this Android community! :P

Thanks for the clarification, I have a baseline to compare to now.

I use Chrome because I like it better than the stock browser but it's not compelling enough to keep if it drains the battery; which leads to the question of how can the browser drain the battery any more than the stock version. Does Chrome operate in the background ? (couldn't see that with GSam).


Thanks again for the help and advice by the way.

I had about a 70% battery drain overnight as well. However, I have sync disabled, mobile(4G) disabled, wifi enabled, auto rotate disabled, no mail accounts, only account I have is gmail, but doesn't sync, and I have no Samsung Accounts.

It's also weird because Maps app shows there, but I was asleep and the app wasn't even open? According to the settings, it's only suppose to update when plugged in? (Note I plugged in the charger prior to this, then sometime in the night the cable got unplugged, so it might of updated when it was charged.)

I am more concerned about the Android System. It seems to be a rare occurrence for the drain to happen so significantly, but I generally leave my phone charging overnight, so I can't be certain; I will try to leave my phone unplugged overnight more often to get more info. Anyone know what battery drain issues stem from Android System?

Maybe I should disable Samsung background processes anyways? Any suggestions?

EDIT: Uploaded pictures.

OK, so I was a bit off, but still pretty darn good. I got full 20 hours on that charge. The usage was rather small, but that is my typical so nearly full day does it for me no problem. Mind you bluetooth was disabled, gps too.

I will do some more testing and go back to using Chrome (I too like it better, although I have noticed some advantages of the stock browser), and re-enable bluetooth, but 20hrs vs barely 10 is a night and day difference (hmmm.. literally!) and very much an expected charge duration so all is cool, I believe.

News on my end... As promised, I am testing some more to get to the bottom of this... And I have some new developments.

After a successful 20-hour-on-a-charge day yesterday, I have turned off wifi (everything else the same as yesterday) and left the fully charged phone overnight (with LTE for data instead of wifi). I wake up 7 hours later to realize a 80% discharge! (20% left!). An hour later, 8 hours since full charge, 10% of battery left.

So because I've left everything else unchanged, it seems to point to the fact that WIFI uses MUCH less juice that LTE!

Unfortunately, this adds a degree of randomness to the phones life per charge as you may not always be in a wifi range. I happen to be, most of the time, hence 20h+ per charge is attainable. Maybe this is precisely why there's been no real statements or attempts to address this by Samsung or Google. Each person has a different set of circumstances when it comes to available data. LTE is sure a drain though. Especially at night when you really don't need data!

Not wanting to monopolize the thread, but I hope my findings are useful to you guys.

I spent most of today around my house (wifi zone) and damn.... This is my 26th hour on one charge with Wifi, Sync, Bluetooth, Chrome, you name it - ALL ON!!! I still have 15% left, so I presume 1-2 more hours. So in Wifi zone: my charge now holds 27-28 hours with minimal use (about 2-4 minutes per hour on avg).

Remember, I came from 10 hours on a charge with no use at all with Wifi OFF just 4 days ago.

Impressive!

I went on to use the phone to find out the battery drain has returned.... 10 hours to discharge (with wifi on this time). So now even I say WTF.... There must be something else that runs in the background and drains it. Crap... On to more troubleshooting...

Update: Back to normal (ie. 8 hours = about 15% drain). Now need to start turning things on to figure out what was causing the drain. Apparently it was not due to Wifi vs LTE (or at least not to that alone).

My suspects now are: Talkatone, Rogers visual voicemail or Skype. It will take several days to find out for sure, though.

I've disabled all non-essential tools, including sVoice, Rogers VV, and a host of others. I left it on overnight with GPS & WiFi off only had minimal battery usage.

It's unfortunate that once I turn it on the battery drains at a ridiculous rate. Whats the point of having a phone that has all these gesture related features, voice activation and homescreen widgets if I can't use them.. silly.

It must be an expectations thing. I'm looking at my phone which has been discharging for 6hr and it is a 70% with light useage and actually a poor service area and I'm thinking it is doing excellent. Of course I came from a phone that would be dead by now.

What I really don't get, what is the big deal about keeping a charging wire by the night stand and other places you commonly rest your phone. Is it really that big a deal to plug it in at night and start the day with a full charge? Especially if the alternative is disabling features you want to use?

This actually opens up a new line of questioning..

Q: Does not letting the battery discharge completely affect performance ? My belief is that if i constantly have it on and off the charger then you won't get good battery life on the days there isn't one around.

Short answer is no - litium-ion batteries do not suffer from the memory effect that occured in older battery technology. LI batteries actually do better going on off the charger rather than fully discharging constantly. That said every now and then you should do a full discharge/recharge cycle in order to recalibrate the battery.

Don't know if others is have the same issue, but my stock video player constantly runs in the background even if I haven't touched it on a fresh reboot and manually end the process. I've uninstall it using Titanium Backup since and use MX Player now, so much better as a player with many options. No more video player running in the background wasting battery...it was using 97% of the CPU at times according to watchdog.

Well, another thanks to John P. I guess I had the same problem -- serious battery drain without using the phone at all, disabled those Samsung services and the problem went away.

The trouble with battery drain diagnostics is that there's actually a lot of different stuff that could be responsible. So in some sense, it may be a better idea to draft a recommended set of diagnostic steps to help solve this wider array of battery drain problems.

For instance, in our case the Samsung apps were responsible, but other apps could just as easily be the culprit for other users.

The ideal battery use for our purposes is clearly reflected with BetterBatteryStats, and seeing how much CPU time is spent in Deep Sleep. If you left you phone idle for several hours, but hardly any of it was spent in deep sleep, that's the reason for battery drain. Before I killed the Samsung services, my deep sleep time was miniscule. Afterward, it was nearly the whole time since my phone was last unplugged.

I found this thread because my new phone is draining overnight. I got to bed with 100% charge and it is less that 50% overnight. I've turned off 4G, syncing, wifi, bluetooth, wireless, motion. I've turned on powersaving options and my screen is so dark I can barely read it outdoors. So everything that makes the Galaxy cool is use is disabled. After reading this thread, I did some research and downloaded some apps. I found my phone is always awake, that Android system is using 60%+ of the battery, and it's mainly suspend_backoff causing it.

One thing I noticed is that my email is constantly synced no matter what. I first turned it to manual, then in case that was faulty tried every 12 hours, yet it was still pushing. I turned off sync all together, but that isn't really feasible when I use this for a work phone and have other accounts I need to sync.

I doubt it's realated but this morning, when I turned off mobile data trying to save battery, I got two texts from verizon with VZWNMN:1. I don't have any custom ROM, so I'm not sure what this was about.

You must not have learnt anything from reading the thread then. You MUST NOT shut wifi off if you want to have any chances of longer battery life. Just re-read the last couple pages (you can also leave full email sync on and shut off battery savings - which is a complete BS in itself).

I think not all the GS3 have this issue.
I had a GS3 which i pre-ordered back in July and it did really have good battery life. Unfortunately there is a problem with the GPS receiver that i could not have a GPS lock and i need to replace it.
The battery drain problem starts with my replacement device. It is terrible. Not only it's sucking juice while using, but also while sleeping. This is very unusual. I'm actually using much less apps than my previous one.

I'm starting to think some batch of GS3 have problem with the hardware or something that's draining the battery. My previous GS3 lasts 2-3hr to dip down from 100%-99%. This is totally something. and believe me i did not compromise any single thing with that to squeeze the juice (4G LTE, always on GPS, all the sync on, auto brightness, face detection etc) . and it still worked perfect.

Now, my view to the GS3 is totally different. The GS3 i used to know was never like that.
How could samsung produces these phone? may b they're using different hardware parts. I don't get it.

I do believe to the ones who're saying they could get more than 1day with full charge as i have had that kind of galaxy s 3. I hope someone could compare these ph side by side under same location and conditions.

Default Draining in Alberta

Good morning everyone!

So glad I found this thread. My troubles have been scarce, but last night was too much. I unplugged my phone at full charge at 4AM. When I got up again at 7,my battery was at 43 percent! No running apps, no auto brightness, no outside syncing besides Gmail and one or two others.

I find if I re-start the phone it helps, but I am spoiled by technology and don't feel I should have to!

I also noticed that sometimes while I am charging the phone, it seems to lag around 50-60 percent. Again, if I re-start the phone, it starts charging again without any issue.

In will try to get in touch with Samsung as well and see when they plan on a roll out of firmware for North America.

Thank you for all of this information everyone!

Wow! you guys are talking about 1 day and 2 days. that is awesome by my standards!

i lose 12% of batt in 1 hour. i only have my wifi on, and on 3G network. one full batt lasts for about 8hrs for me.

I've tried 3 different batts and they are all the same. So at least it is consistent that way.

Hey John,

I just joined this forum to say thanks for you well documented process that you followed in this thread. After getting my phone very recently I was getting really ticked at the standby battery drain and I ran a lot of my own tests before I found this thread. Based on ally testing I can confirm the following:

For me the Samsung Apps were most definitely the culprit and this weekend I decided to barely use my phone at all just to see how much I could get out of it. From the attached screenshot you can see that in the last 48 hours with minimal use I only used up 83% of my battery.

For those wondering for me minimal use meant no phone calls (used my wife's phone), a few text messages, reading a few emails (For email syncing I have exchange, gmail and another account on aqua mail all syncing and all these were on the whole time) and I always keep GPS and Blue Tooth off unless I need them which I didn't use this weekend. Oh and power saving is Off. Also additional information, my phone is not rooted and the ONLY thing I disabled through APPS for this test is the "Samsung Account" app

Also to answer another post earlier I can also confirm in my tests that when I said turn WiFi off in sleep mode, LTE used CONSIDERABLY more power than WiFi, meaning I went from 1% to 2% an hour in standby to 15% per hour.

Hello, everyone

The way I see it, there is nothing wrong with the indicator. With network mode set to "GSM/WCDMA" and multiple apps performing updates and refreshing in the background, there is a continuous switching between no activity, 3g and H+, which obviously drains battery around 6% per hour.

In settings: under "Wireless and network", there is "Data usage". There you can set mobile data limit and get a list of apps using it. Clicking on any of them, gives detailed information and at the bottom of the page the option to "Restrict background data", which disables "background data on mobile data network only. Wi-Fi will be used if available.".

I checked "Restrict background data" for all listed apps except messaging and my weather widget, since they apparently don't transfer any data in the background, but I still receive multimedia messages. Now the signal status shows "H" with no activity (upload, download) while wi-fi is off.

I tested my theory last night: in 8 hours, battery power dropped only 4%.
As far as I'm concerned, I do not need Internet, e-mail, facebook or any other app performing updates, while I am not using them.
This solution definitely is not for everyone, but I suspect it could help the masses
The only thing to watch for is to turn wi-fi off before going to sleep.

I hope this helps at all

Default i agree that

I agree with you friend. I checked in the battery usage and noticed that my phone was awake the whole night and drained nearly 20% battery. then I restarted the device. some times it goes to. sleep mode. some times stay awake and make me to restart.




[QUOTE=DemBones;4862243]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).[/QUOTE]

Default thanks a lot John

hey john,
i am from connecticut-usa at&t user.
i was having the same issue as the title of this thread said.
in my house i and my two brothers have baught total of 3 galaxy s3.
out of those three mine happend to be showing these problems, and not the other two phone.
i really want to thank you and also congratulate you on cracking the root of the problem. that was really hard work.
yr post #170 worked great for me.
but some times i still fear that i am going to have same issue with the phone again. so i was kind of thinking to get a replacement device also, as costco let u exchange it for the new one withing 90 days here.
what u think about it?
i had used yr advice to disable all those samsung apps/processes, it has been 5 days and i dont think i had issue.
everynight i listen to this 30 min song before i go to bed, which is stored on my phone. in my last 5 nights i played that song on my s3 and rest four night i didnt. but on that night when i played the phone went from 50 % at night to dead bettry when i wakeup in the morning. but i am 100% sure i did ended that process in the task manager.
any idea what can be issue.
i plan to check tonight and play that on S3 and test it.
once again thanks for all yr help

in my house i and my two brothers have baught total of 3 galaxy s3.
out of those three mine happend to be showing these problems, and not the other two phone.
i really want to thank you and also congratulate you on cracking the root of the problem. that was really hard work.
yr post #170 worked great for me.
but some times i still fear that i am going to have same issue with the phone again. so i was kind of thinking to get a replacement device also, as costco let u exchange it for the new one withing 90 days here.
what u think about it?
i had used yr advice to disable all those samsung apps/processes, it has been 5 days and i dont think i had issue.
everynight i listen to this 30 min song before i go to bed, which is stored on my phone. in my last 5 nights i played that song on my s3 and rest four night i didnt. but on that night when i played the phone went from 50 % at night to dead bettry when i wakeup in the morning. but i am 100% sure i did ended that process in the task manager.
any idea what can be issue.
i plan to check tonight and play that on S3 and test it.
once again thanks for all yr help

Hey guys,

I've had my galaxy s3 for a couple of months now. I've only been experiencing the battery issue for a couple of weeks now and some days it's better than others. In all cases, the issues seem to be with Cell Standby. But today was the definite nadir.

I took it off the charge at 6 AM and it was dead by 4.00 PM. The only features i had enabled were mobile data, power saving, and screen rotation all day. The phone was in my pocket all day while I was teaching and I literally did not illuminate the screen one time. That's 10 hours of standby and then dead. A check of the battery usage revealed more than 50 percent drained by cell standby. I live in the nyc metro area and use at&t. Unless something like Facebook or twitter is some drawing insane amount of power, this is a pretty heavy defect, right?

Am I right that there's an issue with both the reporting of the cell standby usage and the usage itself? Has there been any update on fixing this issue?

I've read this thread and many others but no one seems to have a true sense of what's going on. What would you guys as given the severity of my issue?

Thanks for any help - I'm an iPhone convert and love the s3 and every capacity so far except this one. Cheers!

Looked up this thread due to a weird issue I had today (May of been a fluke)
Had a full charge this morning, working from home and made one short call.
Then my phone beeps saying low battery ???
Don't have BBS installed, but I do have Juice Defender installed.


Now I did see that AllShare used 4 Gig today alone
Though I wasn't viewing any images, listing to music or playing any vids, so I don't know why that app went all hog wild.

I have a whole other drainer, same as the guy above.
My android system has suddenly been sucking down my battery this week - 47% already today.
I have barely used the phone today and I even restarted it.

Since I see a few recent posts on this I will also put in my 2 cents. After turning the Samsung App off (Post #121) everything was going okay and then one day I noticed that while at my desk at work all of a sudden I was losing 8-10% an hour, restarted many times over a few days to no avail. Then I started wondering if there was something wrong with my work WiFi and was switching to 4G LTE for some reason, so I used this post -- http://forum.xda-developers.com/showthread.php?t=1766516 -- Post #2 and switched my phone to 3G (well it is Edge on Rogers) and that fixed my problem. Of course since the IT person at work restarted the router and it was not a problem for me anymore but I have kept it on 3G because now even with regular usage I get almost 2 days out of each charge, basically have to charge it the 2nd day before bed.

On Nov. 20th I switched over from the Galaxy Note to the GS3. From the 20th to the 27th the battery life was absolutely awesome! Yesterday (Nov. 27th) the phone had been off the charger since 5 AM and I went to bed at 10:30 PM and had 39% remaining! I remarked to my gf yet again about how great the battery life was.

Then today I noticed that my battery was draining much faster than it normally does even though I had barely used it (was just sitting on my desk). Went into Settings --> Battery and sure enough Cell Stand-by was draining the battery like crazy - even more than Screen On time.

I did notice that the GPS active icon was displaying in the status bar so I disabled all GPS related settings (Use VZW Location Services and Use Google Location Services had become checked somehow). The GPS inactive icon now permanently displays in the status bar but I don't think it was always present before today so I'm wondering if that has something to do with it.

Also I noticed just yesterday that in my camera gallery I all of a sudden saw an album that said Kies:wifi - don't know why that is present but suspect its playing a roll in all of this.

I'm gonna try John's suggestion of disabling the Samsung apps and see if that works. I really hope Samsung provides a bug fix for this because it is obviously a software issue and it is truly a shame to see such a great product marred by such a horrible issue.

So I had that bad standby drain to the point where if it was full going to bed, it would be 0% to 10% in the morning when I woke up. Literally did EVERY possible solution, power saving mode, toggling data, wifi off, turned off all location settings, facebook refresh interval to never, screen as dark as it could go, etc... Every single solution, I did and I STILL had the issue.

Well, I went ahead and rooted my phone and installed CM10 with Jelly Bean 4.1.2. That problem is gone. I don't know what that did, but I now lose like 2% an hour in standby mode. So I recommend everyone give this a shot lol

I've posted here before and even made a new thread about how I solved my problems with overnight drain at the rate of 8%/hour but the thread seems to be gone (moderator deletes them?).

Anyhow... the solution I found after 3 months of tests...

WIFI MUST BE ON
ALL OTHER STUFF CAN BE ON TOO (I HAVE GPS OFF)
SYNC AND BLUETOOTH ALL ON
BATTERY SAVING OFF
SCREEN BRIGHTNESS MAX
VISUAL VOICE MAIL COMPLETELY OFF (TO AVOID CONNECTION BY LTE)

and THE KEY TO SUCCESS IS:

EACH NIGHT RESTART THE PHONE!

That's after weeks of verification tests. If I do not restart the phone, after a successful day, the memory build up will be about 1GB. Clearing unused cache does nothing to help. Restarting the phone in the evening does the magic. I charge it back up and an overnight drain is only 8-10% (1% per hour MAX).

With this solution (again almost everything is ON including full SYNC, only GPS is off) I can get... watch this..... nearly 30 hours of standby (and some use) when in WIFI zone (say at my house on a weekend). The drain is very very slow... as mentioned above, about 1%/hour in standby.

Best of luck everyone. The phone is great but that issue should be addresses by Google...

PS. Battery drain when WIFI is not available is always 5-10% / hour. LTE simply kills battery life.

This is a fantastic thread. A huge thanks to John P and everyone else who spent time investigating this issue. I just got a GS3 a few days ago and I got really upset when I realized how poor the battery life was, especially compared to my iPhone 4. Just to give you an idea: today I ran both phones with about the same amount of usage. Both phones came off the charger around 9:30, and by 3PM, the iPhone was down to ~98% and the GS3 was down to something ~60%. This is absolutely ATROCIOUS. Both phones were in standby almost the entire time, connected to my home wifi, and I was running Easy Battery Saver on the GS3 (which turned the radios off while the screen was off, which was most of the time.)

I'd like to summarize all of our findings for the benefit of other users (as well as to confirm that I understand what's happening.)

1) Standby drain bug
In Settings > Battery, there is apparently a bug that shows "Cell standby" as consuming *much* more than it actually does. I read in another thread that apparently some Samsung software dev pulled a Michael Bolton a-la Office Space whereby they moved the decimal place over one spot, so the usage is shown as being very high. However this bug appears to be purely cosmetic, and does not actually affect the battery drain.
In my case, this value has always been at the top of the battery usage list.

2) Chrome bug
There is apparently a bug in Chrome that causes extra battery drain when a specific option is set. To fix this (other than uninstalling Chrome), run Chrome, press the menu key, Settings > Developer Tools and uncheck Enable Tilt Scrolling.
In my case, I had this enabled, so I just disabled it.

3) Samsung services
According to John P (post 70 in this thread, link here) he found a big culprit: the native Samsung apps. He force-stopped 4 Samsung apps (services?) and he found that after a week's worth of use, his battery life is fantastic. Other users in this thread have confirmed this seems to work well.
I'm going to try this tomorrow.

4) LTE consumption
According to yogi799's findings, as discussed in this thread and his own thread, LTE sucks up significantly more juice than wifi, so if your phone is on LTE it will draw more power than if it's just on wifi. The solution to this is to go into Settings > More settings > Mobile networks > Network mode and choose "GMS/HSPA (Auto mode)". This will allow your phone to use 4G, but not LTE (which I guess is 4.5G.)
In my case (and I'm sure most other people) the default is "GMS/HSPA/LTE (Auto mode)" which will allow the phone to use LTE. But I was on wifi all day, so I'm not sure if this affected me. However I changed the option as described above so we'll see.

Someone, please read through this to make sure I got everything correct, and please add on if I've missed something.

I have done the above, and I will be testing out the phone over the next few days, and report back.

I left the phone on my bed side table at 47% and about 9 hrs later it was at 5% so that didnt work to well for me.

In addition to the list below let me add that sometimes the phone just needs to be rebooted. Can't remember if it was in this thread or another one but someone else made the same recommendation. On Saturday out of nowhere I was beginning to see my battery percentages fall faster than normal.

I double-checked my samsung apps to make sure they were still disabled and they were. There was a couple of Samsung services running and don't remember if they were part of the original ones that I disabled but I went ahead and disabled them.

Then I also remembered that it had probably been over a week since the phone was rebooted. Gave it a quick reboot and the stand-by performance has been fine since then.

GREAT NEWS!

I tried out the things I mentioned in post 141 of this thread seemed to have worked, at least after one day of testing.

Before, I had a battery drain rate of 6.6%/hour, with the phone is standby mode nearly the entire time. I've managed to improve this to 1.3%/hour with some light usage, with a minimal rate of 1%/hour. That's an improve factor of FIVE, which is a big deal! My GS3 is now performing just as well as my iPhone 4 (on which I had fantastic battery life.)

Here are the details of what I did:

1) Disabled the Tilt Scrolling feature in Chrome.

2) Changed my mobile network mode to GSM/HSPA auto, instead of the default GSM/HSPA/LTE auto. However, I should point out that my phone always seemed to be on EDGE, indicated by the little E. Strangely enough, never one time when I checked the phone did it ever go on 3G or HSDPA. Not sure why this is; it's something I'll need to investigate.

3) Disabled all Samsung apps. This was the big one, and I believe this is the most likely culprit of battery drain in standby mode. I went into Settings > Applications Manager and selected the All tab. I did a "Force stop" on the following services:
  • Samsung account
  • Samsung Apps
  • Samsung Backup Provider
  • Samsung Cloud Data Relay
  • Samsung Push Service
  • VVM Plus

Note that "VVM Plus" is Visual Voicemail Plus, which is a Rogers-specific service, so if you're on a different carrier you may not have this one.
After stopping all of these, I noticed after 10 minutes several came back on their own; I believe these were Samsung account, Samsung Cloud Data Relay, and Samsung Push Service. So just to be on the safe side, after force stopping them all again, I then disabled each one above by clicking the "Disable" button. This would ensure the services wouldn't start up again on their own.

I should mention that I never signed up for a Samsung account, so these junk services running in the background serve ABSOLUTELY NO PURPOSE WHATSOEVER other than to suck on your battery.

During this day of testing, the following icons in the notifications tray were ON the entire time: Wi-Fi, GPS, Screen rotation, Power saving, Notification, Bluetooth, Sync

I should also mention during this testing I had *no* battery saver application running, whereas before when I had 6.6%/hour drain, I was using Easy Battery Saver.

Tomorrow I plan to run under the same conditions, but this time re-enable LTE on my phone, to see if having the LTE antenna enabled really does have a significant effect on the battery life as some have claimed. I don't plan to re-enable the Samsung services because they're utterly useless.

I'll keep you all posted.

Just in case any of you continue running into massive battery drain even after all of the above are met, I am confirming here that DEPENDING on your situation, a nightly restart may be required...

Here is something extremely weird:

When I am at home (wifi) on a weekend, no restart is required. Drain of 1%/hour is achieved as long as wifi's present.

When I go to work on Monday with flaky / poor wifi and cell reception (ie. the phone battles and hesitates between Edge or nothing and wifi), something hangs in the system. I have the phone plugged in so no worries generally, but when I get back home in the evening, the drain returns just like that (ie. without starting any new apps, etc), ie. about 5-6%/hour UNTIL I RESTART THE PHONE.

This has been tested and verified and I can now control my drain at any given moment, but it's very weird and while I know HOW to deal with it (with all services running which is the good news, bluetooth, sync, all apps that I need, etc) I still don't know WHY..... What messes up the OS and causes the memory "contamination" at my work is the million $ question.

Sorry to bump an old thread, but John P's fix worked GREAT! I exchanged my S3 for another brand new one (faulty home button). The second S3 I received had really crappy battery life. After disabling all Samsung built in apps (as well as Google +, Google Play Books, Vtones), battery life was amazing. Before, I would lose 5% after about 15 minutes. It has been over 2 hours since unplugging from power and I have been using it HEAVILY and I'm at 90%

Upgraded to JB yesterday. Last night, I charged my phone to 100% and unplugged it at midnight. Between 12 midnight and 8am, my battery only dropped 5% , to 95%. Amazing! I was NOT using Power Saver either.


Here is what I have disabled:

All share play
apps
google play books
google play magazines
google+
my verizon mobile
s voice
samsung account
samsung backup provider
samsung browser syncada
samsung calendar syncad
samsung cloud data relay
samsung contact sync ada
samsung push service
samsung smemo synchada
samsung syncadap
verizon tones
yahoo finance
yahoo news

Everything works great (wifi, LTE, bluetooth). No issues from disabling the above.

Well, it looks like my battery usage is still pretty good even after enabling LTE (see my previous post here.)

I should also mention that I figured out why my phone was always in Edge and never switched to HSPA. It's because I was fiddling around with my network selection settings and I had GSM only selected. To access this menu, you go to the phone dialer and enter *#2263# which wbill bring up the band selection menu. Choose the first option Automatic and this will ensure automatic band selection, although this will be overridden in the GS3's normal "Network mode" menu.

With LTE on, I get 2.5 to 3%/hr battery drain. Although this is not as good as my iPhone 4 (obviously) it's still pretty good. I don't have to charge more than once a day, which is what I expect.

Thanks for the input, rcs1. I've tried disabling some of the services you mentioned, hopefully that will help improve battery life even further, and perhaps help some other poor soul who stumbles on this thread.
