I'll keep it short. If WIFI is enabled battery is 100% drained for about 7-8 hours. If WIFI is disabled it lasts around 13-14 hours on complete standby and maximum power saving..still underperforms compared to before the JellyBean upgrade. Has anyone come up for a solution for this?
Some reported better battery life with wifi on because of a router tweak.
We all get eaten up by it.

@halninethousand
Flash custom stock rom that come with tweaks and removed bloatware apps.
That won't fix the wifi drainage.

Hi. I know there are tonnes of battery related threads out there but I would appreciate if I got some personalized help.
I am running Trigger 3.2 Final with Bali v1.8.4 and the JK6 modem.
I have gone through all the modems available for Froyo and JK6 gives the best battery life for cell and data. No overclocking or anything.
The problem is I get extremely bad battery life on data on all modems. JK6 seems to be the best of the bad. With data off, I can get 20+hrs with light phone usage, but the moment data is turned on, the bat percentage just drops like a rock. If I enable data and browse the net with Opera Mini (no flash), a 100% charged battery can be reduced to to around 30% in around 1 hour. Sometimes more, sometimes less.
If it is the battery needed replacing, why do I get excellent cell life with no data activated. Bali is supposed to be battery efficient, but I am bleeding power. I bought those cheap knock off batteries from ebay and get the same results.
Brightness is on lowest, syncs are all off and email checks every hour I think. Nothing else I can think off can be chewing the battery.
I have calibrated the battery many times and makes no difference. I should also mention that I had worse battery life on the bionix roms.
On battery use,
Display takes up around 83%,
Cell Standby 11%,
Idle 5%
What can I do? Is there an app that will tell me if I should replace my battery or anything. I am all out of options right now
Bali Is The Problem
I just read about this same problem from other users, the Bali kernel eats up a charge cycle extremely fast and has even caused major over heating problems!
My suggestion is to go to a different kernel or change the ROM completely to something less power hungry
it could possibly be the batttery itself, mine did this a while back and replacing it helped, maybe even upgrade to the extended battery if a little more bulk doesn't bother you it's a great option try a different kernel, i use Bali and am not overclocked with the JK6 modem and text all the time at school I then got an iPod touch and stopped using my phone for music and it saves me an average of 30% battery 0_o idk why but oh well
I have a stock SGS2 with a lot of widgets running. I use BetterBatteryStats and have removed the high power usage apps.
Past few days, the phone uses a lot of battery at night. Yesterday it had 32% battery and when i woke up it was dead.
Are the rest of you also seeing this much battery consumption every night ?
Funnily enough I've had exactly the same issue since about a week ago. Even when I take it off charge it's almost immediately down to around 80%. It's lasting around 4-5 hours, even when I'm not using the phone much, plus it gets really hot.
A couple of times Social Hub has appeared high up on the list of battery draining apps, although I don't use it. It doesn't always show up though. I switched to the CF-Root kernel and started using GO Launcher EX recently and wondered if that (or one of it's addon widgets) could be the cause.
It's really bugging me now!
I gave up with the stock S2. Rooted it and flashed MIUI to it along with the Siyah Kernel. Now it uses only 6% for the whole night. Battery usage is so much better now.
People having issues with battery should try the siyah kernel and change governors (unless some app was draining your battery)
yeah, actually some new users will experience battery problem. however, some says that when time goes by, the problem eventually sorted out itself.
i am guessing the phone need "warm up time"
I had the same problem with stock rom. you have to remove the preinstalled useless samsung apps. then battery consumption is better.
i am now on cm7. everything is working and around 8% per night with a lot of background processes (tasker, lbe, scheduled titanium backup).
Don't always turn on wifi or data unless necessary.Turn off background sync.This should help a lot even u r using stock rom.Kill tasks with built-in task manager.Make sure useless apps are not running in background.
With these tips,my s2 with rooted stock rom and stock kernel only consumed 3% of battery all night .
i keep wifi or gprs on for instant messaging needs. The Siyah kernel and the lulz governor give amazing battery life because process runs at lower clocks instead of jumping to 1200 unnecessarily.
The stock kernels aren't too bad in my experience.
I think you will find your battery drain will be caused by rogue apps before the kernel.
Edit: why have this phone if your going to turn off gsm and data etc. May aswel turn the phone right off and have zero drain overnight.
A drain of 1-3% per hour with everything turned on is normal for me.

Well recently I bought the Beast S3.
Now I installed this first Kernel - CF-Root-SGS3-v6.4
And CM9 rom, was working great though there's one problem the damn battery drain is like being raped evey 5-10 mins if not less I loose 1-2% battery.
Now I though it might be the Kernel so I switched to Siyah-s3-v1.5.3-CWM, no go still the same result.
I changed my Rom to CM10, same result.
Here's a Screenie of my device (In Attachments)
Could you help out a little? I've checked and not sure where is the issue, and I understand that super huge screen consumes allot of power but even if I set brightness to 0-25% I get the same result...
Most battery issues are caused by installed user apps. Install Cpu Spy for cpu deep sleep issues and Better Battery Statts for locating apps that show unusual activity`s and drain the battery.

This battery drain percentage looks normal to me.
Sometimes I lose 5% without doing anything, even if I have a perfectly cleaned rom.
ok m done with this battery and free ram issue, my battery life is draining so fast on any of the JB roms, its like 1% on 30sec screen on.
i turned back to try ics(criskelo v6) while the rom is great, i get also a good battery i guess, around 7hours screen on, 6 hours of videos and virtually unlimited standby time. the only cons here is that i have 704mb used out of 784mb , also i removed touchwiz, live wallpapers and some bloatwares.
note that checking battery life and ram usage is done with no apps installation, just on the default roms apps. no special app draining battery.
also, battery is taking over 4 hours to fully charge from 10%, even while the device is powered down and on ac charger.
on JB roms like (omega and criskello) battery is draining super fast and charge super slow, but i have over 250mb free rams, on the other side, on AOSP roms (paranoid) battery life is better than other samsung JB based roms, but i get only 100mb free rams.
ok i want to stick with ICS roms for now, seems like JB roms are not stable till now, but also i still have this free ram issue in any rom, any suggestion for this problem,
-is it a kernel problem?
-is it my battery problem?
Try searching for "free RAM" on the forum and read a few of the literally thousands of posts about it.
Short version; don't care about it. Android reports free RAM different from Windows and BSD-based systems (including OsX/iOS), so it confuses users.
Battery life is an issue with JB, true. It'sbetter with the new Siyahkernel but still completely random and not great.
Since the JB update I have been trying to narrow down the culprit in battery drain that has cropped up. Going through better battery stats there was never a definitive clue as to the cause.
Tonight my phone has been off charge 3 hours and its drained 10% in battery sat on a shelf doing nothing, simply because WIFI was enabled.
One of the stand out features of this device was decent battery life up against comparable handsets, now that's been taken away from a shocking firmware update i'm considering jumping ship.
Has anyone else found any means of fixing this yet? Or just a case of waiting for Samsung?

Theres some threads talking about this.
I don´t feel that.I´ m on LJ5 build and sincethe LJ builds I´m very happy with battery drain, even sometimes I get 5 hours screen on with wifi on.
Maybe you update your phone from ICS and don´t wyped your data or made a fresh install. Try to do so and you should be happy again.
It's probably due to a dirty WiFi network that's smashing a bunch of multicast packets. Pretty much all the custom kernels available now have a patch to ignore multicast when screen off; otherwise you'll just have to wait for Samsung to realise they did something silly (read: never)

That makes sense. Always the same with Samsung, takes them an age to get a new software update out and when they finally do it always comes at a cost.
My battery drain is less after settings in advanced to always on and changing the location settings and turning off notifications in some apps and also in play store.
Also in maps automatically update your location might be a battery drain.
I've got a lot of battery drain with wifi on, too. Last night, my battery dropped from 29% to 0% (in 5-6 hours) with wifi on. I woke up to find that my battery had been depleted. UGH!
Must check what is draining your battery. I don t experience that... so far and from many android devices I ve the s3 is by far the battery frindly I have.
I i ve s2 and xperia neo dayly use and I'm happy. I use also some dirty wifi networks and don't have problems at all.

it's a known issue on latest JB rlses. Whats funny is that :
-The leaks did not have the wifi battery drain
- The wifi drains more Battery battery than 3G. I can have 3G on all the time the phone last up to 1d10hrs with 2hrs screen time
I'm on the leaked version. But on lj5 I didn't experience that so far.

Iv had my galaxy s3 for 5 months now and i dont know if its just the Jellybean update but the battery drain when having wifi on is really bad im lucky to get 1 days usage with the phone , i got my google nexus4 yesterday and iv used wifi and data for most of the day and im now in day 2 my battery is at 44% and both batteries are same 2100mah
think im gonna sell my GS3 as the google nexus4 is so much better with battery , but before i do i will reflash stock jellybean on GS3 without root and run them both side by side to compare results , but so far GS3 battery is real bad for drain if i install juice defender on Nexus4 im sure i would get between 2-3 days usage with moderate usage
i will run my tests on both phones side by side with and without juice defender and try to show
I have had the same issue. Though the battery drain is not drastic, it certainly is more compared to ics. If you require better battery life then go back to ics and flash Aosp/Aokp roms
