It doesn't make a difference tried that already.

I did see something interesting though and it has to do with the quad core, I tried with dual core settings and had a great battery life and changed back to quad core and battery drain became bad again.

Maybe it has to do with the battery not right for quad core phones or something I have no idea.

I prefer quad core though because it is faster but it sucks battery life.

I'm not sure if both the quad and dual core phones have the same 2100 mah battery but if they do then surely Samsung should have supplied the quad core with a better battery.

I'm getting an extended battety because I've given up trying to change settings for more life in my s3, I want my s3 to have the settings it was made for and not have to stop apps from working because of bad battery life.

If you want to try it with dual core to see the difference install the Shiyah Kernel and then download and install the extra battery stweak script from his development topic which changes settings of stweaks to dual core and you'll get better battery at the cost of a slower phone

Same issue. I gave it time to settle but it makes no difference.

Process that has the wakelocks is networklocationlocator!

On screen time is 2h 20min

What about maps - settings - locations settings?

Maybe you have location reporting activated
[Galaxy S III General] XenomorphXx121:
I've tried everything from unticking everything all of the location settings, uninstalling apps, changing WiFi settings,disabling notifications from apps including playstore, trying different Roms and kernels and even googling battety drain on jellybean and everyone had same problems without anyone coming up with an answer.

Given up on it now as it only seems to come from international s3's.

Had bad battety drain with ics also and read that Samsung claimed that they'd fix the drain with jellybean which they didn't.

tried to search the word "static" on each page in this thread but found none.

have you guys tried to set up a STATIC IP on your wifi settings in your trusted networks (e.g. home, office)? it helps your battery A LOT.

and anyway, try to disable google now. the network locator drain battery a lot as it keeps asking your location and give you cards and suggestions. and yeah, a tasker seems a nice idea to toggle network locator on and off when you're travelling and such. or keep a shortcut in your home page.

hope it helps.

cheers!

I installed BBS. It says Awake 100%. I am really confused, what is that supposed to mean? Please help!
[Galaxy S III General] XenomorphXx121:
Didn't actually read the first page and glad I did now, better profile zip actually changes to dual core which slows down your phone and it really shows when you play emulator games (check your stweak settings)

As for losing percentage over night think I solved it as I woke up in middle of the night and checked my phone after switching off WiFi and leaving screen off for over 4 hours.

Not sure how exactly I did that, guess it's one of the things I tried.
[Galaxy S III General] Keydogg1:
Have you used Better Battery Stats to confirm this because I'm pretty sure it has absolutely nothing to do with quad core.

Stopping the NetworkLocationLocator has worked instantly for me, my battery only lost 12% overnight (9 hours) which is about a third as much as what it was doing before. My wake time is MUCH better than before doing this fix. Very happy!

See my post above; for this particular wakelock you need to disable Google Now and un-tick "Use wireless Networks to help determine location" in Location Settings.
[Galaxy S III General] XenomorphXx121:
Check my above post, it does have a lot to do with quad core draining battery while screen is on but losing percentage over night has nothing to do with location settings and nothing to do with quad core

I lost no percentage ;)
[Galaxy S III General] terranoid:
9 hour overnight I loose between 5-6% with wi-fi on. I tested wifi off for approximately 6 hours, lost 1%. (From 100 to 99)

Guess if it's on airplane mode it won't loose anything at all.
[Galaxy S III General] XenomorphXx121:
But that way you can't have calls or anything, if you want to lose no percentage with just WiFi off then try one of the things I've tried in this topic that I've posted

Just trying to help :)

I've solved this problem for myself now and hopefully helped others so I'm off to enjoy my day.

Edit: Oh you did manage to lose 1% with WiFi off, I really should read everything before writing a reply :banghead:
[Galaxy S III General] terranoid:
Well, im never using Airplane mode. Its always on network. I wantes to say that, IF airplane mode is on, the battery will last forever :D 700+ hours.

My solution

This being my very first post, I wanted to share my solutions to the now rampant JB battery drain. I know almost everyone who has upgraded to any form of Jelly Bean (including ROMs) has experienced battery drain, either because of Media storage, Media server, Android OS, Google Now or some other system app (as seen in Settings > Battery). Most of what I've read here on XDA and other sites were mostly complaints and unproven solutions. I am here to show you how I reclaimed my battery life in detail. My battery usage went from at least 20% an hour to about 1% an hour, both with screen on and fresh from bootup. Amazing, huh?

You may choose which steps to follow or not to follow. These were not done in chronological order. I am also aware that these are solutions that can apply to any smartphone with JB.

1. I uninstalled DRM Protected Content and Exchange Services. (NOT disabled. Uninstalled but backed up with Titanium). I don't have an Exchange account and the DRM interfered with downloads. You may just disable these if you prefer to.

2. Disabled Google Now, location reporting, location history, location access and GPS. These features are great and all, but aren't very usable in this part of the world. Disable these location settings through Google Maps because Google Now seems to enable these and leave them set.

3. Disabled startup for unnecessary apps using an autostart manager. (Media storage and Download Manager are not disabled).

4. Removed corrupt files which caused Media Storage to continuously scan in the background, thus draining the battery (almost 5% per minute sometimes). This was a tricky one. I tried looking for ways to detect the corrupt files and delete them (like mounting USB storage and scanning on Windows using chkdsk), but didn't find a solution. What I did was I manually deleted my Pocket (ReadItLater) and PlayerPro folders because they were harboring a lot of files that cannot be deleted by the apps themselves. I also deleted unnecessary picture folders/files by using the "Show hidden" function of QuickPic. I also used SD Maid to cleanup any unnecessary files. I'm thankful that there weren't any corrupt files that I missed.

5. Wiped both my external and internal storages. I backed all the files up via USB storage, then formatted them on my phone. I replaced my files after formatting.

6. I recalibrated my battery by fully draining it (until it turned off), removing the battery for about 10 minutes, then recharging to full while the phone is off.

7. Cleared Media Storage data.

8. Turned off auto-brightness and auto-rotation.

I have not installed any battery saving apps, and my phone is running on stock voltage and CPU settings. I hope that this will help someone out there. Reply if you have any questions. God bless you.

Samsung Galaxy S2

[Galaxy S III General] Keydogg1:
If you lose nothing overnight then you have no battery drain problem, anything around 10% or less over 8 hours is just having a normal phone.
[Galaxy S III General] XenomorphXx121:
So you're saying that a battery that lasts just 5 hours when doing normal activities like occasionally using internet and turning off all services like Google now and GPS and every app that needs the battery and not playing games and just using WiFi and losing about say 20% an hour is normal for a phone?

I've had phones that do all this and more and still last a whole day.

It seems like to get good battery from the s3 and make it last roughly 10 hours is to just leave the phone alone with the screen off and just use it for taking calls and sending texts or use it with the brightness turned down so you can barely see it or use other people's methods and hack it to death until it's barely recognisable as the s3 that Samsung released.

This is normal?
[Galaxy S III General] Keydogg1:
What the hell are you on about?? Do you actually read my posts?! I said if your phone loses around 10% or less over 8 hours then this is normal, that's 1.2% per hour - completely acceptable for a smartphone.

Please, read my posts before accusing me of saying something that is the complete opposite of what I have actually written.

An update for those who care: my phone has been unplugged for 15 hours since it charged to 97%, moderate usage this morning (facebook, twitter, whatsapp, couple of calls and texts) and is now at 69%. I'm happy with that, previously it would be down to about 40% by now. So I've had roughly a 100% increase in battery life by just un-ticking one option in settings that I don't care about anyway.
[Galaxy S III General] XenomorphXx121:
I have all my location settings switched off, have no facebook, have all notifications switched off, have display at 50%, have uninstalled apps that use up a lot of battery, have background data switched off, I don't make many calls, have hardly touched my phone or used internet, haven't used 3g internet, haven't played any games and I'm lucky to get 5 hours without having to charge my phone.

I've read all your posts :D
[Galaxy S III General] Keydogg1:
Definitely install Better Battery Stats (and do a bit of reading on how to understand it from his How-To guide) to find out what's eating your battery so quickly, something is NOT right there!
[Galaxy S III General] XenomorphXx121:
I have done all that and done plenty of research about the s3, quad core, roms, kernels, have better battery stats already.

I can get 10 hours battery if I leave it on standby for most of the time but what is the point when the phone is presumably built for fast gaming, Google now which I've never really used but sounds useful, apps and everything else that has amazed me what this phone can do.

If Samsung released a battery with the s3 that would enable me to use all these functions without having to charge my phone 3 times a day I'd be very happy.

The truth is Samsung didn't and I'm waiting patiently for my extended 4500 mah battery to be delivered from Amazon so I can enjoy my phone the way it was made to enjoy it :)

Think of it this way, say you have the fastest car in the world with so many extras like speakers that would blow your head off and sat nav that you can have a conversation with and all these other amazing things but inside the car instead of a great battery and engine you have a hamster running in a wheel to power the car it will get you nowhere and you won't be able to use what it has
[Galaxy S III General] Keydogg1:
You must have a faulty phone surely? I use my phone loads (I have a Whatsapp group conversation with 5 friends and we send around 50-100 messages a day, I'm always browsing facebook/twitter etc) and even with battery drain I was getting 7am-9pm out of it with about 10% to spare!
[Galaxy S III General] XenomorphXx121:
I really don't, I did however have a bit better battery when I used the polish jellybean than the UK unbranded one.

I've factory reset my phone after trying roms and kernels and it's not just my phone.

Do a Google search for battery drain for jellybean or ics and it's a widespread problem for international s3's with many people complaining and many many forums and sites issuing this problem.

I've not seen one person complain about the battery from USA who have the dual core phone.

Samsung claimed it was to do with a battery standby bug that I saw someone have a fix for and said that Samsung would fix this problem with the jellybean update but still many complain about the battery.

Even in xda it's littered with people complaining.

Maybe you got lucky :)
[Galaxy S III General] miro666:
Dear friend

You are pick point with my problem. I was in other thread write some about draining battery from Media Storage and Download Manager processe, because i was think, that problem come specific InsertCoin ROM. But no one answer me.

http://xdaforums.com/showpost.php?p=33334281&postcount=1152

But your post tell me, it is globally for JB ROMs. Ok, i need, if you can learn me, how i can stopped autostart this two very drainer process from autostart. I was make this with Gemini App Manager, but always this two after some time start again. Rest from your post i was make before (SD Maid cleaning). Interesant, i no where can find, how i can stop Gogle Play store auto-sync, like in Gingerbread ROMs, because this is too one very grow drainer battery. Personally i che once per week update from Google Play, no need always sync with it.

At end , one curiositet:

I have SGS I with 3000 mAh, and from full to emty i have 5-6 days. But with SGS III and 4300 mAh battery, i have only 3-3.5 days, all with same draining (30 min calls, and about 2 hours internet on 3G, per day).

Best regards and thank Yu on your opinion.
[Galaxy S III General] Keydogg1:
Maybe so!

Have you published your Better Battery Stats dump in the BBS thread on here? If so has anyone looked at it? Do you have one you can post here?
[Galaxy S III General] XenomorphXx121:
Of course I have posted there ;)

And no nobody gave me an answer so did my own research about my bbs stats, that's how I managed to lose 0% overnight on screen off.

It had something to do with notifications from playstore, notifications from WiFi and an app called applock that kept my phone from sleeping.

They just ignored my post when I asked for help.

I gave you a thanks for trying to help :)
[Galaxy S III General] testadeferro:
I think standard Jelly bean battery is about 4 and 5 hours screen on.

The media things and other stuffs are not so much important on the big battery. Only in extreme cases as some people have reported here. With faulty batterys and other stuff. I think and tested it more or less the great battery drainer in our phone is just the screen. I´ve tested many roms, many stuff and allways same result, 4 hours or a bit more screen on and bye bye juice.
[Galaxy S III General] Keydogg1:
Thanks for the thanks! :)

Right I've just been looking at your BBS dump and everything looks in order apart from WifiStateMachine (Android System) was on 98% of the time causing your phone to go for only 10 seconds out of the 7 hours!

There's something that's keeping this thing running when it shouldn't be, the rest of your dump looks fine so if you can solve this I reckon you will more than double your battery life.

Do you have any wifi widgets on your home screens? Or do you have any Wifi apps which scan for hot spots or tell you signal strength at all?

Also, go into Wifi advanced settings and let me know what your settings are please. Thanks.
[Galaxy S III General] XenomorphXx121:
That was from two days ago from the night before and I have no widgets and I switched all my notifications off from WiFi yesterday.

I have nothing ticked now in notifications and screen on during sleep as never.

I did however have notify me when open network is available ticked which I changed.

I have my latest screenshot from bbs in this topic from this morning.

It's all sorted ;)

Ooh I did have the flipboard widget, never put that there.

It's gone now
[Galaxy S III General] mad0max:
i have problems with wifi on the latest UK rom. when i keep the wifi on the battery drains within 12 to 14 hours and with the wifi off i can use the phone for 2 plus days on 3g i have noticed in the battery usage that with the wifi off the phone keeps awake for long periods even with the screen off and with 3g when the screen is off the phone stays off for majority of the time. i have no idea what is causing this with wifi on. i would appreciate if anyone can provide a solution to this problem.

Cheers to everyone providing help here.
[Galaxy S III General] Keydogg1:
As I said a few posts back > go into location services and un-tick "Use Wireless Network to help identify location". This should fix it.

---------- Post added at 08:29 PM ---------- Previous post was at 08:10 PM ----------

Glad you're happy but you shouldn't have to turn off Wifi to get good results.

Something is definitely keeping your Wifi operating when it shouldn't be. I've got mine set to "Always" keep on during sleep.

Maps>settings>location. Disable everything.
[Galaxy S III General] stevierayvaughan:
Yeah, the JB update brutalized my battery life and I was perplexed until I saw Maps running and I never, ever use Maps (Sygic only), and it was staying awake for quite a while. I just unchecked using Wireless in Settings > Location and it seems stable now.
[Galaxy S III General] AdamLeonard:
I have a Sprint SGSiii with the dual core and ever since I upgraded to the JB, my battery life has dropped dramatically - I lose about 5% an hour while on WiFi. Am just now trying to experiment with settings to try to fix it.
[Galaxy S III General] XenomorphXx121:
Seriously you think that's a problem?

I lose 1% every 5 mins on WiFi and sometimes manage 6, wish I could get 20 hours from my phone using WiFi and sometimes I even manage losing 1 percent in 10 minutes (they are lucky ones).

But if you had better before jellybean then follow tips in this topic.
[Galaxy S III General] waazup531:
What in the hell does multipdp mean? It keeps the phone awake all for nothing.
[Galaxy S III General] fallenwout:
This is not an option for people that have widget/apps based on current location, like weather stuff.

So i left it on. I did, however, noticed a difference if you turn "location history" of in maps. The rapid short wakelocks that nearly filled the whole bar are now much more serperated.

Current battery after 6h 15m is 76% with 45m screen on time. Wifi enabled the whole time, exchange, pop, weather, whatsapp, facebook, ... sync on. It is still a drain of 4%/hr but I can live with that.
[Galaxy S III General] Matcarroll:
Try turning off WiFi for a day and see if it's any better.
[Galaxy S III General] kukhai:
Find an autostart manager app. I recommend Autostarts, or ROM Toolbox Pro. Which processes or apps did you try to prevent from booting up?
[Galaxy S III General] arsenals:
Paranoid Android has excellent battery life.

Left my Wi-Fi on overnight and only lost 4%!

Also, my phones up time has been 14 hours, and with the screen up for 2 hours.

I started on ~50% now I have 30% left!
[Galaxy S III General] ZunRob:
I have the same problem. With WiFi on my battery drains terribly fast. With WiFi off I hard lose any battery. I've unticked all the location stuff and Google Now. I've no clue what is causing this drain. Also see the attached BBS log. All the help is really appreciated!

PrefetcherService always running and restarting

Hi,

i have a Problem with PrefetcherService always running and restarting. It´s from Maps (google maps).

if i stop it under System Settings with the help of the application Manager it gets soon restartet. Even if i dont open or run Maps.

I have disabled all location services. In maps, in latitude, in android settings everywhere i could find. also disabled google+ and googleNow...

is there a way to stop it without rooting? or only with routing?

i am on stock JB

Thanks to all of you!

Yes there's no doubt that jellybean on S3 has battery drain in wifi. ICS was better.

And also project butter is a joke in toichwiz and lots of redraw issue... this is frustrating
[Galaxy S III General] XenomorphXx121:
If you're experiencing bad battery drain after installing any Rom including stock Rom then try this, it works I've tried it.

Charge your phone to 100%

re callibrate your battery (This step not 100% sure about but it works for me)

Take your battery through a full cycle from 100% until your phone dies then charge it back up to 100% again.

After this your battery should be okay again :D
[Galaxy S III General] jnr21:
Calibrating battery just wipes battery stats and they also get wiped when you unplug charger when battery is fully charged.
[Galaxy S III General] XenomorphXx121:
I did say not 100% sure about this stage.

Fine you know what don't try what I said, even though the other bit worked for me continue thinking I'm talking out of my arse.

Nope. Taking ur battery through a few charge cycles after flashing new f/w is a must.
