8 hours gone and I'm left with 49%. With the standby estimation, I should be good to go through out the night. So I hope it should be the same as previous. Just note that I'm a moderate user .
have you tried using zergrush rooting this firmware?

Draining like hell. Can't even last for a day due to radio issue . The issue is there in .283 & .42.
i've not seen a fw that had great battery life...
on cm041, miui the drain was there as well....
what is wrong here....
Slightly off topic: I'm getting about 8-10 hours with pretty heavy usage on CM7.1.0.1. When I leave it on standby, I have about 10% drain after about 8-9 hours of standby, with the occasional time check.
And back to topic, thanks for having the generic SG ROM here, I might go back to this as I have some issues with Wi-Fi tethering on CM7.
Just to add on, i had previously used the .283 version, battery was good. Then i started to root and unlock bootloader, and installed the doomlord v12 for .283, battery drain about 10-15% overnight in 6hrs. Days back, I had flashed the SG ROM .042, the battery was good again, averaging 3% overnight. Its proven to be good.
3% drain overnight is impressive. Which kernel are you using? Stock .0.42?

Same experience as me. But I turn off the data connectivity at night.
As far I used (I used almost all the versions, I guess) the .368 firmware is the best of battery usage. I usually get 24-26 hrs of usage (I would say pretty heavy, with all guns up... [BT, WiFi, GPS]) out of it, compared to this .42 firmware, I can't cross 15 hrs mark!!!
But from what I experimented, I understand that it's the baseband that is giving problem. I notice that there are many users from SG here and specially from SingTel, if you guys observe closely, the network coverage is poor with this firmware compared to the previous .145 firmware. So I'm planning to flash back the old baseband on to the new firmware and give a try whether the battery life improves together with the network coverage.
How do I know which firmware I am using?
Ok, I am on .0.42 world generic now. Let me monitor and revert.

I'm on stock kernel, and i'm using Juice defender Ultimate, let it auto manage my battery-drain stuffs, so i need no worry on forgetting to switch off any batt drain functions. I"m not sure if the SETCPU profiles works, I just enable the profile when screen off I set to 245MHz max 122MHz min. Mine is M1 set.
Kinda tired of flashing custom rom/kernel.. there's always some problem with the features, i.e. 0 batt, wifi cannot connect, batt drain etc etc.. stick to stock for the moment.. Root hp is good enough to play with some stuffs for the moment. Especially ad free.
Personally I don't like any programs that turns off my data to save the battery. It defects the purpose of having data plan moreover, you miss the updates (I've tried lot of applications like Juice defender and I experience the same issue...missing the updates, even the Whatsapp messages are not delivered to you on time).
Now I've flashed the old baseband (from UK .368 firmware) on to the latest firmware (.42 SG) for testing to see how is the battery drainage
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%

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.

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

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!
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.

I remember my 4.1.2 had the same battery consumption and with 4.3 it remained unchanged(if not better). I think you just gonna get used to that .
Use your phone and stop thinking and worrying about battery. Though I charge my phone twice a day because I use wi-fi a lot,I still don't worry or something.

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.

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.

You are right! There is no use resetting the phone. It won't improve your battery's performance. I think it's a bug of android 4.3.

I think you need to try someone else's battery in your phone to see if you have the same problem then

I remember my 4.1.2 had the same battery consumption and with 4.3 it remained unchanged(if not better). I think you just gonna get used to that .
Use your phone and stop thinking and worrying about battery. Though I charge my phone twice a day because I use wi-fi a lot,I still don't worry or something.

Even with wifi on you can use the phone the all day

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.

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.

Hello, let me cut to the point. Testing a few nights while sleeping from around midnight to 7:30am on different firmware versions, i can confirm.
- Stock, unrooted, firmware verison Taiwan, 253: BetterBatteryStats drain overnight : 0.7% per hour
- Stock, unrooted, firmware version Hong Kong, 253: BetterBatteryStats drain overnight 0.3% per hour (Update, last night was 0.1% per hour, woke up in the morning with 100%)
In conclusion, not all firmwares are created equal. If you have the dreaded battery drain problem - try another regions firmware. The HK version definitly does not has the drain problem, and its quite a generic firmware, so you can customize it to your region no problem.
In Both firmwars I had WhatsNew, and all smallapps hidden/disabled via the adb "debloater" app.
PS: Taiwan is original firmware of my phone, I am expat living in Taiwan.
Why HK firmware has more battery? lol

This is the million dollar question. I invite anybody to try and figure this one out!

I also noticed this on my old M2 when I ran customised tw firmware for a while the battery life was way better than the customised UK I was originally running never could work it out.

Nice.I try it.
At now i have this Bat.: -5%(98% to 93%) [0,5%/h] at night in airplane mode.
I try last night HK firmware. And now -10 % in airplane with turned off some apps like google backup,most of xperia apps and etc. Usually i use firm for Russia region also Xpower 3 or 4.In both have a same result 5-7 % per night in airplane.
how do you disable whatsnew without root?
I think the firmware 253 is the same for battery management for all versions.
I think a good thing to do sometimes is clearing cache in recovery. For me it help when performance become slower.
But few parameters can really change your battery drain like the Temperature in your house, usage during the day, network level, running process, humidity....
Maybe that's because some differences of LTE bands support?

I thought the same thing but shouldn't that be more hardware related?

LTE is disable on my phone on all tests. All my testing with done with 3.5G and wifi off.
VoLTE is something i noticed taiwan firmware had, but HK didnt. however I had it turned off in both cases.

I know most people most people would like buttery is the same for all version. That why I am posting. Caches etc all cleared, phone got full wipe when switching firmware.
This test is verifiable and repeatable. I tested both firmware at east 2 times each before posting, and the results were the same every time. Same phone, exact same apps installed, same firmware version - different region = different battery drain.
Can someone upload .253 stock kernel with SU and DRM fix for me? I want to do some further testing but I'm not able to extract it myself for the next week.
the Wifi-allways on bug
did somebody changed already the default:
Settings->Wi-Fi->Settings->Keep Wi-Fi on during sleep
(the good old bug - if you look at the other threads)
one solution I had for battery drain even in marshmallow is to remove the sd card. Yes, I do know it defeats the purpose but I'd prefer not having to worry that my battery will drain by 30% overnight.
SDcard?... did you try another one...
How can I know which firmware do I have? The number is 32.0.A.4.11
32.2.A.0.253 here and I'm seeing Android System keep awake for over 11 hours.
Google Services mobile radio active for 27mins.
No other mentionable apps.
Any luck with the battery drain?
Some good news for me and maybe for others may be helpful.
I flash clean new 305 FW and modified stock kernel from here
http://forum.xda-developers.com/z5-compact/general/customized-stock-kernel-32-2-0-305-6-0-1-t3477464
With root i delete some system apps (mail,gmail,gdrive,maps,whats new, all about small apps and etc.)
Now 3% at first night(9h) after flashing FW in standby mode and all data off without stamina.Its first good result for me.On all others 253 custom kernels was ~7-10% at night sometimes more...
I stay on this FW and kernel.
