[Q] Need to check if this is normal? - Galaxy S II Q&A, Help & Troubleshooting

Hi SGS2 owners and experts. Im new here and a proud new Galaxy s 2 owner now. Im quite android savvy coming from the Spica development from Samdroid. I'v got a brand new GS2 on contract and wondering if the things I'v been experiencing are normal.
Battery life is only 14 hours with light usage and 3g, GPS and bluetooth turned off.
Phone gets warm around the camera sometimes, watching video and browsing the web.
Battery gets warm while charging.
Wifi reception is horrible.
Front facing camera is laggy.
Thats all I would like to know if its normal or should I take my phone back for new one.
Its running on Samsung firmware, gingerbread 2.3.4 XXKI1

For battery life im getting the same and im on checkrom and tried alots of ics rom im the same as u for battery life
And my device is the same the top left of the screen gets worm when multi tasking when the weather was cold i didnt feel it
But now after its summer i can feel my device getting worm abd hot when playing hd games
For battary mmm it gets little worm when charging
But if u use ur device while charging it will get hot ofc
Update to 2.3.7 or 2.3.6 the wifi will get better
Front facing camera yes its laggy
My advice update ur firmware or use custom kernel it will make ur battary and heat little bit better
If i helped dont forget to press thanks

yup all is normal an giv the phone some time to settle like charge and dischsrge cycle...and flash diff kernel an c which suits u.

Ya it's a bit weird to see people still on GB and not on ICS, but for sure update to latest update on GB (or try ICS).
As ayhamx360 said - try a good custom ROM. Look for one that has a lot of users and help. Check what bugs there are and anything else that's important to you (like battery life, heat, camera, wifi, etc).
PS
Most smart phones only last a day and need charging daily... it's the nature of their screens and other hardware excelerations. Newer phones will be coming with better tech that hopefully can consume less energy.
*That being said, with the right tweaks and kernels it can lost longer - mine is usually good for 1 day and 8-14hrs (1.5 days).

Your battery life seems low, but you may need a couple of cycles to get a more realistic idea.
Never had any of the other problems you mention.
I'd try XXLA4 - either stock or as part of a custom ROM. It's very stable.

Thanks for the advice. I sure feel better now. Thought I had a dud phone. Yeah I'm waiting to update ICS via Kies but old sammy hasn't released the update in South Africa yet. My phone is a little new to me to start messing around with custom ROMs like I did with my Spica. I'l prob switch to Cyanogen 9 when its stable.

I remember having much of this when I first got my S2, poor battery life, phone gets hot around camera (the cpus are located behind it) warm whilst charging and although wifi reception was never an issue, it would drop the connection if left idle for short periods of time, (sleep policy was set to off), most these will subside once you've updated to the latest firmware version, especially the heating up, and battery life will improve once the battery has been properly cycled.

[Q] SGS II screen & back becomes hot

Hi guys!
Just got my SII yesterday. After couple of hours use I admit that the phone becomes hot even on normal usage, like downloading apps etc. The back of the screen as well as the screen itself slowly becomes hot. If i continue to use the phone it gets worse! I'm really confused n kind of scared. I've a iphone 3gs which rarely became hot. So, can u guys please tell me if its normal with SII or its just my unit that's got some problem?
Oh, sorry if its a duplicate thread. I've seen in different websites people saying it become hot when playing games. In my case since I had my phone I didn't even install a game yet! What I did is installed couple of apps, widgets and I use mspot to sync my music(446MB) over internet.
Any suggestions and advices appreciated!
It's normal that it gets hot when you use it
You have to remember that it's a dual core 1.2 ghz proc... and Yes it's normal..
Thanks for the replies. What concerns me most is the screen becoming hot and that I don't know if anyone else is experiencing this. How about u?

a part of the issue is it is a 1 GHz CPU overclocked to 1.2 GHz, so whenever your activity demands 100% of CPU, it gets sped up to 1.2GHz and gets hotter than needed.
But yes, excessive heating is not a defect, the phone is just too thin and tightly packed to dissipate heat effectively.
Actually, i dont think it's normal
The processor sometime get stuck at 1.2GHz in my device
whenever ur phone get too hot, go and check SetCPU, if the phone dosent get below 1.2 when idle, then reboot
My guess it's a kernal thing
Not normal. Mine doesn't get hot even when gaming. It used to get hot before I updated the firmware. Now it does not.

I had the same issue, it dissapeared after I flashed to KE7
Thanks for the replies.
Well, it seems yesterday my phone was warming up even in normal usage but now after using the phone for over 4hrs(after full charge) and a lot of usage(videos: 60-75mins, downloading apps, music: 40-50mins, little web browsing & checking fb & mail and sync & wifi always on.....) temperature is around 30 deg celsius.
Next thing giving me trouble is the capacitive menu button which wasn't working at all since yesterday(back button was ok). Last night, sometimes it worked for a few seconds and dead again. I was thinking I should call O2 for a replacement, suddenly its working again today! Guess its a software problem.
Another thing I'm concerned about is the battery life. After charging it to 100% and after the above mentioned usage the battery level is bellow 40% after only 4hrs. Well, brightness was 0% most of the time which is ok for indoor use. Its quite funny that the phone doesn't seem to discharge faster when playing videos(at youtube & vevo) compared to browsing web. In the review & battery tests at gsmarena they mentioned battery life is very good and can last almost a day with heavy usage. What u guys r experiencing? Is it similar to mine or mine has got a faulty battery.
which firmware are you running?
I'm on O2 as u r. So I guess its the same one. If not, mine's build number is ....XWKE2, baseband: I9100XXKDJ
NB: I'm using the stock firmware, didn't root and didn't use any optimisation app like juicedefender. And display brightness is on 0%, always on wifi.
KE2 is a little buggy, you try updating to latest firmware build KE7, might solve your problem.
you can do it if you connect your phone to your pc and run kies, or reading in the dev section of the forums there is a sticky there that informs you how to upgrade firmwares.
Thanks for the reply.
I use mac and the kies mac is in beta and won't let me upgrade(option disabled). I've tried the windows version of kies(downloaded directly from samsung portal) via paralles desktop for mac(lets u use windows app in mac) but it say mine is the latest version(ke2).
And the capacitive menu button is dead again! Is it possible that this is just a software problem? Or should I contact O2 for a replacement? Its my 3rd day with the phone so I've to report ASAP if i need a replacement.
The battery also feels faulty to me. It turned from 100%-1% with only 8hr of usage as follows:
videos: ~75mins(mostly HD),
downloading several apps apps,
music: 50+mins,
little web browsing,
checking fb, rss feed & mail,
sync & wifi always on,
brightness most of the time at 0%,
fring chat: 50-60 mins
And it took 3hrs to completely charge it up. Is it normal for you guys? Or should I request for a replacement? Any suggestions appreciated!
i have debranded my phone from O2 and upgraded to KE7 from kies, but if you cant do it that way you can try upgrading thru odin.
http://forum.xda-developers.com/showthread.php?t=1075278
This thread has multiple firmware versions and instructions on how to flash your phone (please note, if you decide to flash your phone, you do so at your own risk, even thuo the risk is quite small).
As for battery usage, i have rooted my phone and frozen a lot of bloatware, if i leave the phone on standby with wifi off the battery drains lest than 1% each hour, with wifi on its about 2% each hour.
Also i find that when i play angry bird a lot i have to recharge after about 6-7 hours, when i watch videos my phone heats up a little, it heats up a lot if i watch videos while charging.
hope that helps you, if not talk to the ppl at O2 to see if you can get it swapped out, but i think if you can get your firmware upgraded your battery drain should reduce and the shouldn't heat up as much.
Thank u very much for the replies. It looks like battery draining is normal for all SGS II users. Its kinda funny that playing videos over internet eats less power that browsing web(27.19min of HD video playing at vevo over wifi drained only 5% of battery!).
So now everything seem ok except the capacitive touch keys which sometimes which doesn't work most of the time. I'm just scared to use custom roms as it might void my warranty. Well, I'll try the link u mentioned and see if the problem still exists.
Thanks again

[Q] Its official. My Galaxy S2 is busted.:(

Hi guys just wanted to say my galaxy s2 is officially busted. Its still in working order do not get me wrong but something wrong with the hardware i think because i have flashed so many roms and stock roms to try and resolve the problem and i cant. My display is always sky high in battery usage and i cant get it down to save the life of it. Got everything on the lowest that is brightness settings and still nothing. Spoken to samsung and they say its not suppose to be like that and that display always high and as high as 60% is not right.
What can i do please cause i love the phone and it really pisses me off that it gets drained so bloody quickly? Shall i just sell it and get an HTC sensation instead or shall i send it to Samsung and be patient for ten days without my phone

Id say just wait for the new phone, the galaxy s II obliterates the Sensation. This coming from a person who's owned both devices.
About your display problem, sounds pretty weird never heard of an issue like that before.

What is your average display "Time on" on "Battery usage" when you're almost running out of battery?
How quickly does it drain? Don't you have warranty to get it replaced if it's actually faulty? I can't really decide if that's the case from your non-sense post.

My display is high as well with android Os in second most of the time and its normal, cause I use the phone a lot so obviously the screen will be high.
I get around 13-17 hours heavy usage so am happy I dont think its anything to do with rom flashing unless you get lower then 10 hours battery life
sorry i should of made it more clearer. Once i charge my handset as soon as i start using it you can see the percentage drop rapidily. i go into the battery usage and the display is at its highest and draining the battery. And that is with brightness to low settings. If i do not use the phone it can last me for a whole day and a half. But im to scared to use it for browsing and thats over wifi cause i know it will not last me to long...i know the handset is a battery drainer but come on the display should not be as high as it is..and with the warranty i have put the stock rom back so can they find out still that i had my handset rooted if i was to send it in

If you get two hours with screen on, than that's normal and not a hardware failure. Use white backgrounds as little as possible.
Apparently they could, I believe they some kind of count record of the amount of roms you have flashed and the only way to reset is by using a 'JIG' if you search the forums should be able to find more info on the 'JIG'
http://forum.xda-developers.com/showthread.php?t=1068522&highlight=jig+to+reset+counter
you might try some of the other forums about reseting it
Looks like SAMOLED+ consume most power on SGS2. I thought it's normal. Just know mine also having the same problem.
Sucks to be the guy who receives all these problems. I suggest, you just get a refund, as you should be ashamed of yourself if you sell a defective SGS2.
If you like the sensation, get it. It's also good, as I usually borrow it from my sister when we feel like exchanging phones for a few days. Sensation's default battery life is a little worse than the SGS2, as I only get 18hrs-1d 4hrs in the Sensation(still not rooted/default ROM) against the 1d - 1d 10hrs of the SGS2(Leomar ROM + Ninphe 2.2/undervolted).
My sister just got those chichitec 1900mAh batteries, and she said battery life on the Sensation improved(Only her word, as we have yet to exchange phones again this weekend). Now, all it needs is an undervolt + good ROM and the Sensation's battery should last a longer if not the same than the SGS2. Though you'll surely miss the SAmoled+ quality if you compare it with the SLCD of the Sensation, hope HTC improve on this department, they should have used IPS instead of SLCD.
A little tip if your getting the Sensation, is to thoroughly check its touchscreen sensitivity. My Sensation, is a little buggy sometimes, sense lagging/resetting + weird touch sensitivity. Though, I think it should be fix by flashing a good ROM + Kernel. Good Luck.

well im going to fully charge it again today and see how it goes. i have reverted back to stock rom and just rooted with chainfire kernel and installed titanium backup and unistalled all the samsung hubs and froze the wifi sharing bit. but my display is still high but i see how long i can get out of it i will post a screen after i let it drain down ..
and sorry to hear that you are having the same problem.

what is your display percentage and how can you manage to get so many hours out of it? any tips? i will be posting screen shots tomorrow for you guys to see what im talking about
If you have been using the phone the screen will always be #1 on the list, as its the part that needs the most power.
The phone will get about 6-8h of screen on time total before the battery is flat, but it will depends on mobile coverage (weak coverage will drain faster), if you are using heavy data, wifi usage (will be better than using mobile data on a weak signal or if you are pushing a lot of data round).
Generally radios will eat up the juice.
Also games will hurt.
You can use CPUspy to see what states the CPU is in, and if its going to deep sleep.
Also in settings > about phone > battery use, you want the awake and screen on lines to match up as much as you can.
(Music will keep the phone awake while the screen is off, and so will downloading stuff etc)

The truth is, that what you report as a problem, is not a problem, it is simply a fact. SAMOLED displays drain batteries like hell. Mine does exactly the same. Like you, I was starting to think that my unit was somewhat faulty, but soon fund out that it was not. In fact, the truth is that the galaxy s2, if left on with the acreen at normal brghtness, fully drains its battery in a matter of 5 hours or so. It is due mainly to the display draining something like 0.8 Watts, alone.
People saying they get almost 2 days use simply tell bullocks, because there's no way of actually using this phone and getting more than about 15 hours autonomy from its battery.

Moving to Q&A
Samsung support/RMA process has worked very well for me. Third phone already. Maybe ask them to replace yours?
I'm still confused over there. You're just talking without making any sense at all. The only thing I've got from all this is that you're complaining about display being the highest on the battery drain list. That means nothing. Or not much at least. Those values need to give a total of 100%, so if you're using your phone, and display is the highest, your phone is working really good, and you don't have the AOS bug. Which means your device is not faulty, you just don't understand the battery statistics screen. Pardon me if I understood your problem wrong, but if I didn't, just carry on with your life, your phone has no problems at all. I get around 1.5 days with medium usage, and I think that's normal for a phone like this.

You are not being rude at all. I have flashed yesterday batistas new rom and using jeffrey speedfrey kernel and i have fully charged the phone and calibrated it as well. I am going to let it die down and recharge it again to the max and see how it goes after that as well. My point of this though is as below on the screenshot. The display is always in that percentage and that is what has me worried. I have checked on other posts and the most that they get is 35 to 50%. I have the lowest brightness settings and it still that high..That is why i am asking if there is something wrong with my phone. I am getting good battery life so far just with medium usage and having wifi on since i have charged it but the display is what worries me. If someone could help me with these pointers as well i would appreciate it:
Does underclocking with Setcpu help battery life even more?
And what do you guys think of the screenshot?
i know this sounds silly but how does someone close a thread once they opened it i have a few i want to close..
Thanks again to everyone for you help..
It has dropped to 76% after 10 hours and a couple hours of screen usage. I don't think that there is a problem.

[Q] iPhone 4S vs. Samsung Galaxy SII

Hello all,
I'm currently a Samsung galaxy s2 user, just switched from using the iphone 4 because of all the rumors about the galaxy s2. And till now im impressed by everything it has to offer except its battery life.
I love my galaxy s2, but the only problem is battery life, and thats the main reason im being pulled over to buy the iphone 4s!!..
getting that isnt the problem..
I tried way too many custom ROMS, different kernels etc, but ended up with an average 6-7 hr battery life with heavy usage and that doesnt even involve listening to music while commuting. If i did that as well, im sure my battery wud barely last 5 hrs... which isnt ideal at all, im sure everyone feels the same way... Right now im on stock KI3 firmware, rooted. KI3 is slightly better than what bell gave me as stock - KG2.
now i want some strong points of why i shouldn't move back. I've been an iphone user since the 2g iphone and it was amazing!
Only if i could improve my battery life on galaxy s2 i wouldnt have these temptations to move to iphone again.
Should I move back to the iPhone?
no, galaxy s2 is the best !xD
my battery is very good so i don't care just try some kernels or roms
iPhone 4s is much better than SGS2 IMO.
Better size, better display (imo SAMOLED+'s colours are too cartoony), better resolution, better camera, better audio, much better battery and a much faster processor.
Also, iOS has proper dual core optimizations and actually makes good use of the A5 chip, wheras with SGS2, you'll have to wait for a stable ICS rom comes out.
Despite the negativity of the i4s, I personally think it'll be one of the most underrated phones this year.
But that's just my opinion.
My s2 often gives me 16+ hrs of heavy usage (my phone is from the first batch) my other half got a white s2 a few weeks ago and he has dreadful battery life. Both same firmware ect. Although mine is made in korea both battery and handset. His is made in china. Different colour mainboards too. Mines blue his is green.
Sent from my GT-I9100 using XDA App
Well just to make the point clear, you will never get your sgs 2 to have as much of a battery life as the IP4S. iOS is simply much better at handling battery life than android.
Now it depends on what you want really. Do you value battery life over functionality/choice?
Personally what do you expect of a phone with a dual core 1.2ghz processor? If you expect 12 hrs now that is simply idiocy. You have a laptop that can do that? I don't cuz mine lasts 2 hrs with heavy usage. I haven't read of any laptop being able to last 12 hrs of heavy usage either. No I don't expect a laptop to have a battery life like that either. Now this is a phone with a processor better than most if not all netbooks, it is not going to have a 8hr+ battery life with heavy usage just like a laptop.
I feel your pain with battery life. Also, screen burn in isshowing its face on mine too. But threw iphone is waaaaaay too locked down to make it an easy choice.
Sounds like you dont have things set up correctly to me or your using some resource hogging apps.
Im on wifi all day, send between 40-70 sms a day, couple of phone calls, tweetdeck auto updating, around 20mins of music (well, podcast, but it is an audio file), auto updating of all my apps enabled in the market and the obvious hour or so web browsing and 10mins or so of minecraft when I sneak off for a break in the toilets and I get home with around 30%
Dont forget, your also comparing a closed up OS which has been around for a fair old while to an open one which is still reasonably new which each phone manufacturer has his way with before chucking the phones out
Im not going to fight the android corner as you admitted yourself you are 'looking for reasons to not move back'. Which sounds as though you have already made up your mind.
If you want to go get a shiny fragile phone with a half eaten apple on it by all means do Glad you've at least tried Android though, your light years ahead of 90% of Iphone owners who live around here lol.
must be something thats killing your battery in the background. I quite easily get over a day and between 5-6 hours screen on time. Longest ive had was 6hr 38 mins screen on.
Download better battery stats and see whats running in the background.
Lawl you all are missing a very important statement in his post. "HEAVY USAGE"
What is heavy usage? Web browsing, playing a 3d game, watching a video, recording a video, taking pictures, etc. So of course he is going to get 6-7hrs of battery life.
I agree with the above post. find out whats draining your battery. Shouldn't be that low...unless you are just sitting on your sofa browsing constantly because your so excited about a new phone like i was.
Also you can buy a dock charger and extra batteries set for cheap together (ankhers set) so you never have to plug your phone into a charger again
But it sounds like you have alot of money to burn...then why not...being in a locked system isnt so bad when your willing to just buy every app and media at premium prices and your happy with the interface
Thanks for the quick reply guys, and yes, i m loving my galaxy s2 as i mentioned earlier. And yes, im a heavy user, around 100 texts, playing 3d games (sandstorm, brothers in arms etc). I barely keep wifi on as i haf 6gb of data which is almost unlimited. and im getting 7 hrs, which apparently seems to be good. If thats the case then I have nothing to complain about...
And in terms of money, lol i dont have any... its just i could get an iphone if i sold this one... no way i could afford to keep both!
Stick to the SGS2 and wait for the SGS3 till then.
Hmm, If were I, I would like the iPhone 4S. The iOS 5's new feature iCloud and iMessenge really attracted me.
And can get many apps for it:
http://www.enolsoft.com/blog/best-free-iphone-4s-apps/
SGS2! iPhone4S is inferior in many many ways. It's a ****ty phone.
/ownership bias
u should wait untill the ICS rom is out. that should improve the battery life, because it will be customized to a dual core processor.
Iphone 4S is quite a good phone, but I'm personally against Apple's politics regarding software and price. I don't want Itunes, no format support like FLAC or MKV, no Flash. Also Android has more customization abilities in themes and menues.
I like the big screen and weight on the GS2. Well, the battery life could be better on SGS 2. But there's a Samsung 2000mah battery available at the moment and you can easily replace the battery.
I have been in the same boat in fact I have swapped my Iphone 4 for a SGS2 three times, until finally I realise that the SGS2 really is a SuperPhone.
The reason you will find battery life not quite as good as the Iphone4, is basically down to the fact the Iphone is not actually doing a lot.
I waited until iOs5 before swapping back to this truly, greatest phone since the HD2, iOs5 really is a disappointment to say the least, you get a pull down bar that kinda copies Android to a point, but fails in the fact with its Iphone basic-ness yet again, the weather links to the most basic of weather apps, the notification animations appear at the top all very nicely, but the top bar doesn't state that notifications are listed within, they tried to match the Androids version but in true Iphone style, didn't leave in the design to allow users to feel its their notifications.
One thing you will never get away from even jailbroken is the fact you are not free to choose...you will never own your Iphone, it owns you, Android on the other hand is the opposite and with the SGS2, its power and freedom is far more adaptable than the iphone4.

So I'm on stock LA4 GB. Contemplating flashing LPQ and wondering beforehand how the battery life is?
I have BT/Wifi/3G on all day with about 1-2hrs of calls max in a day and on GB I reach around 20% battery at 6pm. Phone leaves charger at 8am.
What's to expect with LPQ? Any firsthand experiences so far?
I did not tested yet the LPQ in full radio but so far I am liking its battery life performance.
let's wait for others input..
Cheers,
Unwired
ics standby time is normal and most likely same like gb rom in term of battery life.
but usage time ,ics seems to eat more juice ..
but i believe after several cycle of full charge + calibrate , it'll be normal too. just like gb
I installed it and I'm about to start my day.. Right now it's pretty nice. G+ update fixed the crashes but I'm unable to detect my Bluetooth earpiece and that's a deal breaker as I need it for when I get calls while driving.
I installed LPQ yesterday and I'm going back to GB 2.3.6 because of the battery life. With GB I could last almost 16 hours of moderate to heavy use. Today, with moderate use, it lasted me roughly 8 hours. This is a deal breaker for me because I'm on the move all day long.
It was a disappointment because it looks almost as GB but with lots of glitches on my favorite games and apps, battery drainage, and crashes. I guess I was expecting something more like Vanilla Ice Cream Sandwich. I wish there were no OS fragmentation on stock Android. Something more like iOS. My iPod Touch from two years ago looks exactly the same as my mother's brand new iPhone 4s.

I have to agree, battery life seems abysmal compared to KK5 2.3.6 or even LA4 (which to me was worse than KK5)
It's good if you got no sync or data but then that's not the point.
ICS is really pretty and all but if I get half a day out of my phone it doesn't matter.
That's from 4 days worth of experience
There are too many variables to say objectively. Like comparing roms & kernels, whether they be GB or ICS. Any comparison will be purely subjective.

I would agree however I have the exact same apps installed as before with the same setup. Only difference is I'm using facelock and I'm playing a little more with the phone because ICS is new but barely. So I'm hoping they get out an update soon that smoothes out the battery life
hi
i think the difference in terms of battery life between gb and ics is custom kernel. kernels like speedmod or phenomenal 4.0 extreme help alot. since ics has no such kernels ((
i installed ics and i'm pleased that is stable. if u want battery life than my advice - STICK WITH GB
Stand by time is almost the same but when you use the phone either playing with it or whatever ICS eats the battery.
How on earth can you measure battery life when the rom is not even a week old and the battery has not had chance to recalibrate itself .

I don't mean to act like a spoilt kid, but when I'm going to work and using my phone as usual and it starts beeping about low battery ~2hours earlier than usual I feel a bit concerned and that's what I'm voicing out here.
If you have any advice concerning the recalibration and how to accelerate it I'd gladly take it over waiting for weeks.
Also when you're talking about recalibration as necessary, you mean that the phone/battery would think it is at x% when it's in fact at (x+y)% at any time t?
I sure hope that's what it is.

Horrendous WIFI Battery Drain since JB Update

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
