Jellybean Battery Drain Discussion - Galaxy S III General

Now, I know that we have a "All your JB discussions here" thread, but I think that this one is a rather specific issue and hence should be discussed in a separate thread. I also know this post is rather lengthy, but please read and give your opinions as it's important.
If you look at the last 5 pages on the JB discussion thread, you'll notice that lots of people are complaining about the battery drain due to wifi. The gist of it is that if you forget to turn off wifi before turning your screen off, then you'll experience a battery drain of about 5% an hour even though you're not doing anything with the phone.
I can vouch for the wifi battery drain issue. After flashing DLJ4, doing a factory reset, doing several full charge cycles, etc. here's what I can say:
On ICS, battery drain when the screen is off is the same regardless of whether you leave wifi on or off. Approximately 2-5% overnight
On JB, battery drain when the screen is off and wifi is off is the same as ICS. But if you leave wifi on, it drains about 2-3% an hour.
General battery use on JB otherwise is the same as ICS
It's pretty obvious. You don't even need to use apps to monitor battery use. Anyone can easily tell that there is something about the wifi causing battery drain.
So there are 2 things to note:
1) Wifi strength on JB is much stronger. For example, I could never connect to wifi from the 2nd floor on ICS (the modem is on the ground floor; it always shows poor signal and gives the "authentication error" when I try to connect), but now on JB I can easily do so within seconds of turning the wifi on. And this result is consistent each time I try.
2) With wifi on and the screen on at the same time (eg: when browsing), the battery drain is similar to ICS, ie approximately 1% every 4 minutes.
Point (1) seems to imply that the wifi strength on JB is stronger, and maybe the frequency used is higher. This seems like a pretty good explanation for the battery drain, until you consider point (2). Point (2) seems to indicate that the problem is not in the wifi frequency, as battery drain during screen-on time is similar (you would expect it to be higher), but there is some other explanation.
So my idea is that the wifi is indeed stronger in JB but that doesn't affect battery drain significantly. Instead, the problem lies in the fact that wifi management on JB is just bad. On ICS, when the screen is off, the wifi signals are probably "weakened" significantly, for lack of a more technical term, but on JB it remains at the same "strength" as when the screen is on. This is probably what causes the battery drain.
I'd like to use this thread to see what everyone else thinks from the experience on stock JB roms. And of course, if we can properly identify the cause, surely someone would be able to fix it.
Update 1: Alright, so far it seems that only those on stock kernels have this problem. Those on Siyah kernel appear to be unaffected. I'll test it out soon, and see if it can be a temporary fix for now.
Update 2: So I've been using Siyah kernel 1.7 RC1 for nearly two days now. While the battery drain due to wifi is reduced, it's still not as good as it was on stock ICS. And this is even after I flashed the "better profile.zip". Also, as a side note, the overall battery consumption on Siyah isn't significantly better than the stock kernel. But at least wifi battery draining seems to be less. Do continue posting your experiences so we can find a more viable solution.
Update 3: Over the last few weeks I've tried out DLJ1, DLJ5 and the leaked Rom with multiwindow (can't remember the Rom name). Anyway, from my experience, and from the collective opinions on people who posted here or in other battery threads, it would seem that the WiFi battery drain persists in all these jb roms. The only solution I've had so far was to use Siyah kernel. Some people report that custom roms work too, but I suppose if you're reading this thread it means you're trying to fix a problem with stock jb.

Wifi battery drain is bad on my s3 too. :crying:
I thought it was just some wakelock issue. hopefully the next jellybean update will fix this

I'm on the latest DLJ4 and I had wifi on last night. I unplugged my phone from charger at 3:00am then woke up at 6:30 for work and in that 3.5 hours I had only lost 2% battery, the whole time wifi was running.
Maybe it's kernel related, I'm running Siyah 1.6.8 and I don't seem to have a problem.

I'm on stock kernel. Perhaps I'll try out Siyah kernel, but still there a quite a number of us facing this issue, as you might be able to tell from the original JB discussion.

I've been on Omega since version 25 (now on 31) and I have 0.9% per hour battery drain with WIFI on. I've used BBS and found all of the main drain causes on my phone and stopped them. For instance, I have location services turned off and even disable\freeze maps when the screen turns off (I have a tasker widget to defrost and open it when I want it).
On my phone the OS doesn't have a problem with WIFI battery drain, but various apps and services did until I sorted them.
Edit - my drain is the same despite whether I run stock kernel, Phenomenal or Siyah.

I'm on siyah 1.6.8 and have no decreased battery life.

Well are you sure ? please answer My problem is the WIFI speed su** it always shows no bar or 1 bar all the times and speed is horrible after seeing your comment i think JB update is worth a shot

Maybe we need to add:-
These problems are only on stock jb roms, not flashed kernels or custom roms. A large amount of people on stock firmware on jelly bean have this WiFi drain. Its very obvious on my phone, with WiFi on and screen off, I get around 4-5% drain, with WiFi off and screen off I get about 0.5% drain.

And I thought that this problem on my phone only ... I wanted to do a factory reset, but you say it doesn't help, so no point trying.
With the JB benefits, there are still annoying bugs.
1. When accessing a Settings tab, notice how it opens. There a chubbiness in the Settings app. (tried to clear data etc etc ..).
2. TouchWiz Redraws very frequently.
Other than that, I can't see any problems with the Official JB.

I don't get drain Lj4 WiFi on overnight max drain 2-3 %

I know these aren't methodical tests, and they're still quite subjective. But it's pretty obvious to most of us that the wifi is stronger. By the way, what do you mean that you don't see that sort of drain? On ics or jb? Because on both ics and jb, my battery drains about 1% for every four minutes of browsing and I find that normal; pretty good even

I'd like to add that after I installed the stock jb it wasn't the WiFi I had a problem with it was my network connection with virgin as my signal was very low, about only two bars and my s3 used to get very hot when it wasn't doing anything.
After I left my screen off overnight and checked bbs I found that the main problem causing battery drain was losing connection and bad connection and my s3 got hotter the more it charged.
I tried the Shiyah kernel and flashed the even more battery zip I've notice that I now have a full connection and it hasn't dropped out yet and my battery is draining very slow and my s3 is very cool which I am really happy about.
Edit:After a full cycle the quad core seems to be draining less, seems the Shiyah Kernel is the best Kernel for battery life with Jellybean

Yea got the problem too ...if I use my phone on charge it slowly (I mean really slowly) charges...and it takes twice as long to charge my phone. When I returned my phone to stock (ice cream ..etc) it goes back to normal.
But wanna thank this thread hopefully changing kernel will help

I've just noticed something after using stweaks, if I change to dual core my battery drains slower and the Celsius of the phone is lower but if I have it on quad core my battery drains really fast and the Celsius is much higher.
I read somewhere that it's only the international versions of s3 that have bad battery drain and the other versions use dual core, not sure if that makes a difference.
Also noticed after changing to dual core my s3 only lost 4% over night, I also undervolted the battery a bit.
I installed the wattage widget to see the differences.

How about folks running stock DLJ1/2?
I had flashed DLJ2 French stock version previously and I feel I had better battery at that time than DLJ4 UK unbranded JB (which I am on right now).
And I dont think we are getting enough complaints about battery life from folks who are running versions other than UK DLJ4 ROM!

DesireZ ICS Battery life, is yours worse?

Hi all,
Just wondering if your all seeing reduced battery life with the ICS builds for the DesireZ?
I was using Miui (2.x) and now trying out Ice Cream JIBWich,and Im discovering the battery life is most certainly less. I've also tried CM9 Alpha and Andromedus r13, all roughly the same.
Battery Widget reports on average 40(ish)mA in sleep, I havent compared it to Miui but just wondering I've done something wrong here..
Install procedure this time was a factory wipe.
Comments?
Angelo
I don't know if my battery life is worse on ICS than on CM or stock 2.3. Because I don't have any logs of battery life. Maybe I will do some tests in next week, just for curious.
So... I'm getting 30mA - 34mA drain on idle on Andromadus v13 with default kernel. It is lower than yours. I'm using latest radio now (.19).
After implementing new features and fixing bugs, there is a stage of development called optimization. That is when you will see all the battery life milked out of a rom.
And none of the ICS roms are even close to that stage, so battery will probably not be indicative of the final product.
I don't have any hard numbers, but based on my moderate usage, (8am to 11pm) I go from 100% to about 40%. Fairly good IMO when compared to sense roms (that i'm used to) but not as good when compared to AOSP GB or MIUI roms..
Hmm I found my battery doing suprisingly well compared to aosp gb, now that I'm using ics its lasting longer than ever.
It probably has to do with better app/process management.
That's my experience..

Well, this might sound strange to say but i'm actually getting the best battery life i've ever had out of ICS so far with Andromadus v13/Jibwich 1.3 on my phone. I seem to manage to get really long charges of at least 48 hours. Maybe i'm not using my phone as much as i was with GB? I'm not quite sure if that's the case or not, but i'm consistently getting longer lasting charges than ever before with GB.
Thing is though that ICS ROMs DO seem to drain the battery more while the phone is actively being used (in comparison to AOSP GB ROMs), this seems to be the case for me, as well as some other people that i've seen.
There were a few strange versions of Andromadus and Jibwich though which seemed to cause severe battery drain for me. Fortunately, that hasn't been the case with any of the latest versions.
All of that said, i still don't think anything compares to the battery life on G2 Slim (Gingerbread AOSP ROM), that ROM has ridiculously good battery life. With that one, i'd use my phone a fair bit (couple hours of tethering, gaming, lots of texting and calls) and it would still last for at least 44 hours or so.
In the end though, there are still some GB ROMs that have much worse battery life than ICS for me. For example, all CM7 variants that i've tried has always had this frustrating radio related battery drain, then some Sense ROMs seem to drain the battery a bit more than AOSP ROMs too. In response to the OP, i never really got amazing battery life with MIUI, so ICS has been a much better experience so far in that regard.
What i do know for sure though is that battery life with ICS is MUCH better than the stock gingerbread OTA update that our phones got.
thanks all,
I've done some checking and according to battery monitor, my JIBWIch rom seams to be fluctuating .. from 36mA to 97mA in standby which to be indicates something's running.. not sure what... Anyone recommend a decent process monitor, there's soo many of them

Agreed..
I'll see how it goes but I might have to go back to Miui (GB) as I use the phone for work..

Here was my (personal) record breaking charge on Andromadus v13 https://www.dropbox.com/gallery/12263406/1/screenies?h=c9ef42
You can see part of my configuration there (radio and CPU speeds).
On top of what's already there, i use supercharger RC6.9 with option 6 and nitro-lag-nullifier.
here are my usage patterns for good battery life:
-I generally stick to 2g networks as i don't do much web browsing while i'm out but when i do, i just switch to 3g.
-I also don't regularly use any task killers but if i detect any choppyness i kill app using Advanced Task Killer.
-I don't use auto-brightness and instead i just use the notification power widget.
-I do lots and lots of texting, some calls here and there, i often use wifi hotspot and i play 2d games a little bit at times, so i'm generally a light-moderate user.
-I also "debloat" as much as possible by getting rid of any system apps that i don't use.
On a random note, right now, i'm using Jibwich 1.3 and it is so great, battery life seems the same as andromadus v13 but this ROM is actually much more smooth and fluid on the home screen.
I hope this helps a bit, give me a thanks if you found this useful ;D
hey thanks for this, yeah very nice!
Just occured to me, im currently in Madrid (Roaming), and the phone's on 2g at the moment, I WONDER.. just wonder, if its constantly hunting for 3G signal.. now that would account for the random power demands...
Meanwhilst I found this app http://androidadvices.com/save-battery-android-phone-enabling-2g-network/
Apart from adding a 2g/3g toggle it also makes the phone go to 2g when sleeping.. I mean when its sleeping we dont need 3g access....
Anyone else tried it? or can recommend a different better/app?

Go to settings --> wireless and networks --> mobile networks
Now see if you have "use only 2g networks" checked. If you do, that'd be why you're always connecting to 2g networks.
As a battery saving tip, it's best to always check that option when you don't need mobile data (like when you're at home and wifi is available).
In addition to that, if that option is NOT checked, then your phone will connect to 3g networks where applicable, you have to check if your carrier actually uses 3g networks on your plan.
Also that app seems fine, but i wouldn't use the "use 2g when sleep" option because that could cause problems with reception between waking and sleeping because it'll be erratically switching between basebands all the time.

It looks to me that yes. Tried 3 ICS inluding JIBWich and CM9 based and battery life was reduced to me about 1/3 maybe 1/4. looks like that. Hope some improovment will come in near future.
I'm running Andromadus v13 and it seems to be only a bit worse than the latest CM7 nightly. However, this is only my subjective opinion, it could be that I'm using my phone more with ICS
I also have the .19 radio and the tweaks associated with v13.
Well from what i've seen, ICS has very steep and sudden drops in the battery stats graph when the phone is being used. This is in contrast to many gingberbread ROMs which just have a sloping negative curve on the battery stats graph. This seems to indicate that ICS uses more battery when the phone is being actively used.
I'll post pics after this current charge is over to show a comparison of ICS battery life with Andro v13 and GB battery with Virtuous G-lite 2.0.1.
I don't see any difference between GB and the ICS battery usage, maybe because i allways configure it from begining and don't restore apps via titanium backup or any other app...
Also battery needs to calibrate under new ROM and after few charges you will see it working little bit longer and longer...
ps. Do you have disabled Google Talk on ICS fresh install? He is always on after installing and eats a lot of battery.

I also configure all new rom's from begining and on Affinity 2 - my battery in averange usage die after ~16h but on ISC os about ~13h, I don't know why.
My battery after full charge get 4.212 V , tried clear battery stats bin no effect
My avg runtime on one charge on CM7 w/o oc, with ilwt or pershoot kernel is 60hours (yes! 3 "work days") or atleast 2 days with 50-70 min calls and 25-35 SMS
Turning data and/or wifi when needed makes phone battery least looooonger...
Now testing Andromadus Audacity b1, charged 7.5h ago (4207mV), i will post when empty (or near ~3600-3650)
Also remember that we don't have the proper kernel source for our phone. There are some tweaks that can't really be made yet, and probably a bunch of wasted cpu time where errors and stuff get worked through.
GB battery life was worse than Froyo at the same stage of development. It'll even out better when we have the official kernel source for the DHD, I think.
Sent from my HTC Desire Z using XDA
So most ICS based roms have roughly the same battery life?
I'm current on the audacity beta, getting about 20 hours with no charge with moderate use. Gingerbread i could go about a day and acouple more hours.
I'm a bit bitter that I can only use 3G or higher on Bell with my DZ...that means if I want better battery life I need to ditch mobile data altogether. Boo.

Better battery life
All,
I was just about to install "Elitemod", which claims to be tuned to bits wrt battery life, and I noticed AudicityBeta1 was released.. so i thought Id try it out.. and
And yes I think its much better!.. this morning I used it a bit, made a dozen phonecalls, sync'd email and for the first time the "voicecalls" are less than the screen.
(see attachment)
Im wondering if the recently released qualcomm drivers made a difference..
At this rate it will last ~40hrs... probably less but as long as it lasts the day Im happy
Anyone else want to confirm my findings?

Curious observation in battery life on ICS LQ3

I have noticed accidentally yesterday that after I had my stock headphones pluggeed in the Note, the typical curve of the battery drain became much flatter and the different wakes during screen off have almost disappeared. The moment I unplugged the headphones, the battery drain went back to the usual 2-3% per hour on standby.
I am running stock LQ3 and stock kernel. I am rooted, as I have flashed it through Mobile ODIN, over stock, rooted LPY.
I have quite a lot sync-accounts - twitter, facebook, gmail, email, weather widget etc. so I am quite used to relatively short battery life but the trick with the headphones came as quite a surprise.
Before writing this post I decided to test it today as well and it is the same.
So, could someone test this and report? I think that if this proves to be true and common, the devs could easily track what's happening exactly and sort things out, so that battery can live longer without the headphones plugged in.

Ugh...I am terribly sorry, this was meant for the General Discussion. Please, admin, move it there.
I've noticed that same if the SAR of the last samsung mobile is very low, the reception is quite good compared to other phones.
Do you notice also an improvement of the signal reception? Because if it is the case, it is that your headphones are used as a secondary antenna, giving the phone a stronger reception and less power consumption (better signal = less need of power usage for processing the signal)
This is just a theory...
After some ICS ROMs I went back to Gingerbread, mainly due to poor battery life.
When Litening ROM 2.0 was published I flashed that one. I liked the GB version a lot. The battery life was remarkable, a lot better than previous ICS ROMs. Because Litening is not much supported I tried Alba, also LQ3. A surprise because battery life was the same. I think I'll stick to ICS this time.

Alba often uses LB2 modem (from GB) in his ROMs - maybe it is the reason. I myself observed huge batterey drain on latest ICS ROMs while connected to Wi-Fi at my workplace. Fixed it by flashing ZCLP5 modem (from early "LP5 leak" ROM).

Hm, that is an interesting theory. I am not sure, however, that the headphones' cable really improves GSM radio reception. I think it is only for FM reception. Of course I have no knowledge behind that, just thinking.
I have frozen lots or apps in Titanuim Backup like:
- the whole range of SNS's
- Social Hub
- Wi-fi sharing manager
- the infamous wssyncmlnps
- software update service, etc
Also I have stopped a bunch of receivers, using Autorun Manager Pro, and disabled a lot of processes from Autostarts.
This should mean that I have opted out the most common battery drainers. I have tried to disable auto-sync for the time being, but that does not seem to be much of a drainer, so maybe the real problem comes somewhere from the modem.

Hey dimcus, i've been having this WiFi vs battery issues with some routers(including the one at home), weird enough it doesn't happen on some of them. I did read somewhere about flashing te Modem file, what leads me to a couple of questions ir you don't mind. Are you on ICS? Do i need to be root to flash the Modem file? If not, any risks involved? I'm on stock ICS LPY DBT.
Thanks in advance,

I flashed the ZCLP6 modem earlier today, guessing that it would be better than ZCLP5.
It is too early to judge but first impressions are that maybe there is a slight improvement in battery on 3G but not something worth it over the stock XXLPT that I used to have and generally battery drain on wifi seems as bad as it has been ever since I flashed ICS.
I have read that some people dared to wipe their Notes and after that most of the problems had disappeared but I don't want to risk getting some brick.
I will try several other popular modems and will report back.

Please let us know how you get on with them. Currently on LR1 modem and noticing a few strange wakelocks.
I have been with LR1 modem for about 40 hours now. What is better than the ones before is the much better behaviour on wi-fi. Other than that it is hard to tell any differences. So far 7 hours since unplugged, 1 h screen-on, half time wifi, half time 3g - battery is at 75%

wow.. that;s great.. i upgraded to ICS 5 days ago.. super poor battery..
then I heard to go with speedmod kernel, which I did.
no change..
Can you'se tell HOW TO change the modem?? I need to do something... mine just dont last worth a crap.. half day..
should I try a modem? and can you please say how to do just the modem??.
my baseband is N7000XXLPT
and build # is IML74K.XXLPY
thank you!
Unfortunately after several different ICS Roms (From Stock LPY to Cleanote 2.20) with several different Kernels (Stock, SpeedMod, Goku and more) and few modems (XXLPT, ZCLP5) I had to go back to Ginger due to extremely poor battery life. With all roms /kernels/modems combination the behavior was very similar. The phone was going into deep sleep pretty easily when idle with very low battery drain. On the other hand when using the phone I was getting about 10% drain each 20 minutes (A little less with data wifi and all sync off). I was also getting overheating with temp most of the times over 40 deg C. This drain was almost the same even with system energy savings on. I could not understand the reason for this strange behavior considering that many other users are having great battery life on ICS with their devices. Anyone is experiencing this situation ? NB now with Ginger the battery life is ok.

Battery drain with cm10 paranoid android
I am facing a huge battery drain issue. Used the phone for downloading and playing games and general usage yesterday and battery only lasted 3.5 Hours. Need to continuously watch the battery as it drops about 10-20% on idle. Checked the wakelocks and mainly wifi related, the phone is going into deep sleep just fine. HELP PLEASE!!!
lol continuously watching means you're the wake lock.
btw phone only has 3-3.5 hour screen on time. When playing games its usually less.

Battery worst on JB than ICS

Hi Guys,
I am on the Three network in UK. I recently updated my to JB and immediately noticed that the battery performance has deteriorated. I used to get nearly two full days with a 2 - 2.5 hours of screen time, 1 hour talktime and 1 hour music and little maps with GPS. I can merely a day now with the same usage. I would like to mention that the standby time was brilliant on the last update I received on ICS. Is anyone facing the same issue. I am thinking of of doing a full factory reset. Not sure if that will solve the problem. The battery graph shows that something keeps the phone awake

I flashed the french version last night and I literally only got my S3 yesterday too and I can't really comment on the battery life compared to ICS but the battery life is way better than on my Xperia Play... Anyway I intend on trying out CM10 soon.
for me the other way around
ICS used to eat battery faster.
everything depende on how you setup and how you use your phone. it's not as simple as ICS > JB or JB > ICS
All the leaks I used, including the Polish Rom, had rubbish battery. H3G is working fine. Even better than ICS (or about the same).

Yep getting similar battery as that screen shot... Seems to be a lot of wake locks also I have realised even with data turned off it still drains battery as if it was on... On ics with data off I would lose like 2% over night bit with jb data off I lose 10±% battery easily over night... Hoping this is fixed soon... I though jb is suppose to be more efficient than ics?

I know how to disable Google Now, but how to disable S-Voice on a stock (unrooted) ROM other than simply "not using it"?
Like an earlier poster, I used to get huge battery life with ICS by turning data off overnight etc, however now with JB it seems to drain much quicker.
I'm only sync'ing the minimal essential things as before, pretty much exactly the same settings, so disappointed in the battery life.
I made a point of doing a full wipe both before and after the update to be sure of starting "with a clean slate".
Some people have said that battery life should improve after a few days. Why should that be? Is it busy housekeeping its flash memory or something?
Did you try Settings->Application Manager->All->S-Voice->Disable?
Works for me.
I'm the same. Ics was much battery. I have turned everything off, disabled everything unsynced everything and batteryvstill draining at 3-4% per hour, whats the point of a smart phone if you can't use it! My battery drains pretty much the same whether the screen is on or off!
I found battery life in JB to be poor IF my wifi was connected - with wifi off or just disconnected battery life seemed to be similar to ICS. I use wifi a lot though, so for the moment I've gone back to ICS... wifi range and performance seemed to be lower in JB too for what it's worth.
Im loosing 2% overnight using foxxhound
Sent from my GT-I9300 using xda app-developers app
I get roughly 10-15% more juice out of JB with identical apps and settings.
My battery life is a lot worse on stock unrooted UK BTU JB aswell ... didnt even get 10 hrs out of it yesterday ... doing a full wipe and restore just now but its taking hours to put my apps back on ..
Didnt take this long to restore a iphone or is something wrong here ...My back up is only about 300mb and its been about 3-4 hours and still just at 50% complete ...
To be honest, that looks alright to me. 17 hours with network on all the time? And look at those wakes while the screen is off.

oh really that means I should be getting better because I am on 2000mah but it seems not. Im not sure what's the problem if its the battery or the kernel. I also used an ICS firmware from Samsung I9100TDULP4. I don't know if that affects the battery life

To callibrate battery..first completely drain the battery to about 5%, then charge the phone non stop without disturbing it till 100% and immediately remove the charger..again fully drain the battery and follow the above steps and u will get better battery life after a few cycles!
About roms..battery life does differ from rom to rom...i suggest u could check the custom kernels packed with zzmoove governor, ithat particular governor definitely improves the battery backup!
And in the above post es file explorer is eating ur battery..for that u should download greenify and hibernate apps continuously running in background!
great. I will follow your steps. one more thing. how can I know if the battery is still good or if its still holding the proper charge its suppose to have? thanks

best I can get is about 3 days standby in jb stock.
I use the 2000mAh battery is primary battery.. no big surprise to expect here, capacity is just 21% more by construction...
With wifi on, JB burns in my case about 3% in IDLE.. stock kernel.. and about 5% in 3G mode, IDLE.. then battery drains more or less fast depending on screen on, phone calls etc. I use the phone extensively for work (email sync & replies, phone calls, sms and voip) and i have to topup the battery twice or trice a day!
Have tried various custom kernels with all sort of magic to reduce battery drain.. more or less effectively.. sometimes with less stability.
Right now trying out latest dorimanx 8.27.. seems thatn IDLE with WIFI on drains around 2% per hour.. better than stock.. still not quite awesome
I miss the GB battery life.. but JB is so beautiful in comparison, I cannot go back!

Does Jb stock for you has better life or does custom rom have more? I really like the custom roms but as per observation stock rom offers more battery time. Right now I just reverted to stock rom i9100xwlss. Touchwiz really sucks. Supernexus is really beautiful but offers less battery (but I will have to try yet their latest build). Also one of the reasons for going back to stock is the camera shot quality. Custom roms really have poor camera quality. I guess when it comes to lowlight shots the stock roms are best. So much for that. Does stock rom offer more battry for you or custom rom does?

Below is a reply in some other forum by Samsung offcials regarding a specific method to Hard-Reboot your phone after a Firmware update: This method particularly helped me improve the battery life on SGS2 after 4.1.2 update.
"1. I’m sorry you are having issues with your device after upgrading the firmware. I can understand your frustration about this.
Old systems settings can be left on the phone after an update occurs, which is why we usually recommend a full factory reset after updating. If this isn’t done your device may begin to give false readings from system resources, or experience technical problems, which may explain the issue you are having.
We would advise on doing the following, which is designed to reset the settings on your device. Please back up your device using Samsung KIES before you do this.
1) Remove the battery for at least 40 minutes, put the battery back in and allow it to fully discharge. Afterwards, perform a full battery charge with the device turned off. Do not interrupt the charging process.
2) After the battery is fully charged, we would like you to perform a full factory reset, which can be done via Settings > Backup > Reset.
This process will reset your device, remove old system files that are no longer needed and enable your device to operate normally again.
Please let us know if your device continues to experience problems after the reset so we can investigate further.
If you require any further assistance, please contact Samsung again and we will be more than happy to help.
Kind regards,
Stewart

Actually I only use stock JB.. and trying to get it last longer with some custom kernels.. recently trying snapdragon rom, which is stock JB as well but with some S4 apk made compatible with S2... tried some time back omega, vanila rootbox and some other android builds for s2.. but was facing few stability issues / bugs and also missed some features that i was getting from stock rom.. so i gave up with these... now just aiming at stability and if possible battery endurance.. but not at the cost of stability.

[Help] Battery problem

My battery is draining too fast after upgrading to android 4.3. Even only on 2g there is 1% decrease in battery almost after every 3 minutes. But with screen off it will remain almost at 99% after even 12 hours or more. But when I start using the phone for something like even navigating through the settings the battery drops 1% every 3 minutes or even less. My handset is about a month old. I am from India and running the ML4 android 4.3 recently released by Samsung. There is no wakelock when the screen is asleep. The phone screen consumes between 60 to 90% of the battery or more. I factory reset it thrice since the update but with no effect. I am running the 4.3 update for about 3 weeks now. I also installed Greenify, battery doctor, juice defender etc to save battery but there is no improvement. I installed the same apps that I installed on the 4.1.2 firmware but the battery is draining quite faster in the 4.3 version. I also freeze almost all bloatware using Titanium backup and even uninstalled some like Google Books etc. but no use. I don't use wifi or wifi hotspot at all. I rarely use bluetooth. GPS, location, etc off. I even freeze Google Play store, Google play services and Google services framework. No multi window, no smart stay, no s voice, no ripple effect, no live wallpaper, etc everything off but still the same. If there is anyone facing this issue and has already found the solution, please help me out.

It is normal battery drain.
Battery on 4.3 is almost same as 4.1. What else do you expect its a quad core phone.

This is funny! You mean to say that the upgrade to android 4.3 has damaged my battery? The battery is not even 1 month old as I mentioned in the first post. The battery is very good on android 4.1.2...... As I mentioned in the first post, there is no battery drain when the screen is off. Even after 24 hours the battery is 99% from 100% with screen off. Why should I checked for wakelocks when the battery is fine on screen off? I did checked it to be sure but no wakelocks. The battery problem is when I use the phone, the battery is draining abnormally when the phone is used. Anyway thanks for your reply.

Using BetterBatteryStats will nevertheless help you to find out which process is consuming your battery…
Yes, 4.3 upgrade downgraded my battery life about 20% when I am using my phone. On idle it is better about 10-20% also compared with 4.1.2. It is useless to do factory resets or other nonsense. Just it is as is.

Okey So Firstly I rule Out Few Assumptions Made By Some Members(No Offense):
1) As thadoukuki said battery Drains only while using the phone and not wen its idle that means its not a wakelock for sure.
2)Secondly as the handset n battery ofcourse, are just a month old i dont even assume it to be damaged(Trust Sammy)
3)Thirdly 1% / 3Mins is quite normal on extensive Usage but as you say its just while navigating around settings etc. den i assume its a bit high.
4) Now betterbatterystats is good to identify what consumes your battery but ive never been a fan of that actually.
SO according to me try to do some trial n error work .
Instead of Freezing apps through TB u can use Greenify Donate to greenify system apps and user apps as well. It Does same job as TB freeze but without that extra hassle.
Secondly Choose a kernel that you think is battery friendly for you like the one which gives you peace of mind(Oh Yeah Battery's Draining Slow!!)
for me i'd go for Boeffla or Googymax
Choose a battery friendly Governer for ur CPU(For me Boeffla kernel with Archi_ultra_power_save governer gives great results)
Check if CPU Touch boost is Enabled in Kernel Settings coz Touch Boost gave me good performance and responsiveness but even i had observed that battery used to drain faster with it.
Battery friendly Rom with few Tweaks by xda members is always better for me over Stock( ArchiDroid Is the Rom ive ever Used){Personal Opinion}
Ppl Say undervolting helps .....hmm maybe ive never Done it but as you are very cautious about battery you may try it (on your own Risk)
Lets see if that Helps
And Lastly i never Observed much Change in Battery drain pattern wen Coming from 4.1.2 to 4.3 so thats not really true.
