I read few thread and tried like Calibrating Battery, Clearing battery stacks etc. I'm has flashed the ftf file and Pre-rooted image. The draining issue only happens if the WiFi is On. If I turn off the WiFi it works just fine. Otherwise the device will get heated and the battery will go down like crazy, Within 1 hour around 10% goes down when the phone is in idle. I turned off all the sync. I re-flashed the firmware as well still no luck. I only have Launcher Pro and Widget locker installed rest is stock. I removed few apps like Fun download etc. I also freezed Maps using Titanium backup. My only theory it could be a buggy kernel because it didn't happen in the previous build. But I also tired with DoomKernel (test version) no luck. I'm kinda scared to flash the old firmware back because I see lot of RED Light issues. What else you think could be the problem?
try the stock kernel. remove unwanted apps from system or freeze them via titanium backup
try the manual network search instead of auto. and lastly try the stock kernel

i have exactly the same problem with a NEO, all stock no root no nothing, there is for sure a problem with this firmware.
I'm still on the 2.3.3, but i have noticed a similar effect. This was caused in my case by my email program (com.android.email). By killing the service, the batterydrain went to normal. By starting email again, the batterydrain goes to around 10% per hour and a warm phone. Also there is a lot of bandwidth used!!! up to 20 mb per hour.
I finally got off my lazy ass and jus tremoved all my email accounts and am re-adding them now one by one. Up until so far, it does seem to work.

The phone stops charging the moment it reaches 100%...!!! When charger is removed it goes down to 99% in few minutes...!!! Earlier it used to take 4-5 hours before coming to 99% from 100%...!!! Everything else is fine...!!! I don't think that just keeping the wifi on causes such a battery drain for me, but yes if i keep surfing and keep my display on the whole time then it drains around 15-20% an hour...!!!

I have the same issue, it started on .368 firmware.
now I'm getting weird battery status readings, for ex: when charged to 100% after few hours of not using it reaches 60~50%, I turn it off, pull out the battery and put back in then turn it back on, it shows 80~70%
im having serious wifi problems, anyone know a safe method to flash back? i just got my phone replaced to, i dont want to run into the 0% battery issue again
I have the exact same battery issues since .368. For example, I unplugged the phone 24 minutes ago at 100% and now it's down to 97% on stock kernel (.283) and with the screen off the whole time....

I tried the stock kernel as well. Still the same problem. I really like to know if it's hardware or software.
I am having the same problem, with lots of heat generated when making calls so much it makes my ear sweat onto the screen. Also there is a huge amount of heat generated when i use data, the battery reduces at 1 % / minute when using data, and also quite a bit when im using the music player also. I hadnt noticed this before as i wasnt using it for every day use because it was sim locked. im scared to go back firmwares because of the 0% battery issue. Im not interestd in root is it ok just to flash back and not root?

Thanks for the reply.
There are just the system apps, the keyboard, the clock widget, music player equalizer, e-mail client and setcpu... basically the same apps as before, as I didn't do any major change since I was on .145.
I checked for maps and it wasn't running.
I guess the battery life is indeed poorer since the last two updates, but at least they have better RAM management than in .145.
Anyways, I have a computer around most of the time (either at home or at work) so I can always charge it, but it's a bit frustrating to see the battery go down like hell when I'm not even doing much with the phone. I mean even a friend of mine who owns an SGS II has slightly better battery life, and that's a dual-core...

It is definately the android system. There is another thread here where the samsung rep says they know about this version of android and the battery issue. My tab went to zero yesterday in ten seconds. It took me a long time to get the battery meter to show it was charging again.

Has anyone tried calibrating the battery? I just received a Tab for testing and it was used prior. Some battery monitor apps reported less then 12hours available after a full charge. After I calibrated it, i'm getting ~28 hours / moderate use before battery is depleted. What amazes me with the Tab is that when idle (overnight) there is no decrease in battery levels and graphing shows a complete flat line when idle.

I have done all of the battery recalibrations suggested here on xda to no avail. The only thing that has helped me is plugging in a portable kennsington battery by usb that tricks the battery indicator and it seems to slow down my battery drain.

Try doing a resetting on the tab, and do a full charge, I mean let it charge for 8 hrs continuously.
If it can't work, bring it to Samsung for firmware upgrade (takes about an hour), after which do the same, long charging.
Last option, ask for an exchange with Samsung.
Rooting it has never been my option

Hey guys, I was in the same boat (you can see my posts on other threads) and I have tried pretty much everything from flashing rom, resetting, calibrating, and bump charging. Last night I decided to open up the tab and look at the battery, thinking maybe I should buy a new battery to test.
Long story short, I disconnected the battery from the board and let it sit for 15mins before reconnecting. I check every couple hours to see the battery level in android. So far, I only lost 1% for 20hrs in flight mode w/o any app running. I usually lost 20% overnight and would regain that after reboot. So the problem is GONE and the system is reporting the right battery percentage without fake dropping.
I will continue to monitor it and report back, but it looks great so far. Hope this helps other XDA fellows.
Thats actually ive been wanting to do just prick it open, funny though i my problem resolved it self, last night i keep rebooting my tab up to the point it hangs and froze then i left it like that for an hour then i pressed the power button for around 10 seconds to reboot it again, once it booted up it showed the correct percentage, now im still monitoring if the trick went well..

Hi Shinji, it is quite unbelievable that the tab only drain 1% for "20hrs". But it is great, if opening the tab can solve battery issue. Now, I myself encounter some other new problems, after I solved the sudden drop in battery issue by upgrading to new firmware (e.g. 50% => ask me to shut down). Now, no matter how I charge, it will remain 67 or 70%............
Do you have the instruction to open up the tab, or any link which you can lead me too? Thanks.
Hey henrylam do you charge phone whilst on and how long do you charge for before you get fed up waiting for it to move from 70% and remove charger ?

I try both, on and off, sometimes it work sometimes it doesn't. After I have done factory reset, it seems ok for first 3 cycles. After that, the problem surfaced again.
Sometimes, it just stop charging at 65 (curvefish battery indicates) but battery icon shows like 85%. I felt like smashing the Tab and get myself a new Ipad. I am thinking to send it again to Samsung this Friday, and let them investigate for a while (hopefully 2 weeks will be sufficient). Damn it, my wife tab has no such issues. She didn't even do an upgrade on her firmware.

I have this issue on Darky 10.1 (2.6 kernel), 2.3.3
Battery lasts around 10 hours with light to medium usage (its a new original Samsung battery as well).
Does anyone have any quick advice to fix this? Bit under time pressure due to job at the moment and don't have much time to research this. Any advice to fix this easily and quickly?

It's been through quite a few cycles.
I think I figured it out.....I think it was Skype. If you sign in the app is always on...it doesn't have an exit feature. There is, however, an app to close it. I used it and got normal battery life today!
We'll see if it keeps working like it should.
So I've upgraded to 2.3.4, (Ficeto.Deodexed.XXJVP) and Android OS battery drain stopped. Now it shows 70% battery usage on display (before it was 70% android OS). I recommend updating your system too
with darky on medium use never had more than 14 hrs )
I've given up for the moment and gone back to Darkys 9.5
Now at least I can get through one whole day and have about 40% left

Are you willing to flash the rom again? or you can try to use the speedmod 15g t11 for the kernel to replace the JVP kernel.
it's said that when you use the USB connection to your PC, you need to reboot it. So this battery drainage will not happen.
In the ROm 2.3.3 JV5 and JV6 for Asia, I do the same to keep the batter alive.
Try backing up everything and then factory reset phone. Generally this happens because of a few unwanted applications excessively using ur processor, in turn draining battery or there may be a malware that stealthily connects itself to the net. This will almost certainly cure the disease. If it doesn't, then there is a serious defect in ur hardware or some of ur system app required for properfunctioning of the phone is corrupted, causing excess pressure on the processor
It is a big problem to everyone, I charge twice per day for this.
Calibrate your battery
Let the battery go down to 0% and turn off
Then turn the phone on, it'll turn itself off again cause battery is low
Keep doing this until its totally 0%
Plug in the charger, charge it to 100%
Turn the phone on
Download SGS Tools from the android market place
Run the app
Go to "scripts"
click delete battery stats
Unplug charger & you're done
battery should be more stable now
go to settings
applications
running services
check what you have in the background
close them down if they're unecessary
I get through the workday with only 10% loss
If you have an really old SIM card, try and replace it with a brand new one. This may also help. I had bad battery run time with two LG Optimus 2x phones (about 10 hours) and not so stellar 20 hours with the i9000. Finally I stumbled over some advise to replace old SIM cards. Since mine was over 12 years old, I ordered a new one. It is not gonna change the world, I know, but it was worth a try .
After a week of research I figured out what was draining my battery. It's a system process related to Google backup. So, here's the tip:
* in Settings->Privacy disable "Backup my data"
* restart the phone - yes, you have to, otherwise the process will continue running
* enjoy!
Before disabling the backup service I used to get no more then 12-14h on a charge. After disabling the service I get 48h.
This service seems to be a problem with Samsung firmware only, it has no effect on battery use on my Desire HD.
I've tested this on stock XWKF3 (2.3.3) and XWKI4 (2.3.4) firmwares. Let me know if it's been effective for you.

Your battery lasts 4 times longer after disabling this? Do you expect anyone to believe you? Probably not.
Let me try n get back to u aft a few days
I think he got a point. I am at %67 in 7 hours. I use to spend more than %50 in 7 hours, that is, my battery will be depleted in 21 hours instead of 12-14 hours. Not x4 times but almost twice the battery life I had. I am not using any power savings, stopped green power. Wifi on, 3g on. All battery consuming widgets, e-mail check every 30 minures. Facebook in the background and Skype, and Fring, etc...
Thanx for the tip. ıt really works for me

i also had my batt lived longer when i freezed wifi sharings, im, market updater, accu weather, radio and gmail which i do not use. Believe it or not, i topped 82 hours. My record. Without these i was getting 24 to 30 hours. Without widgets let me say.
82 hours was on 2.3.3. Now with 2.3.4 it is around 72 hours.
My emails are in push for every hour. I use my phone moderate to high by talking, internet over wifi and edge, and my phone is always on edge not 3G or H.
I believe that there are certain ways to increase your battery life. All you need is to find it how.

I wonder what you loose if you do it though??? (calendar entries, contacts etc)
Cause I don't wanna loose my contacts which are up in google servers
I ll try it I guess I get around 13-18hrs depending on usage ( Just copy my contacts to sim card first )
EDIT: Ah I think its ok its just for applications... not related to google account or so I believe
Current state 7hrs 18mins and 68% battery remaining will see how it goes
this isn't so new...

Thanks for the tip,mine has always been checked so i have unchecked it and hopefully battery life will get better.
The topic pretty much explains it. I've been using different modified stock roms and now I'm on the latest nightly of CM7, and I keep having this issue. After a reboot at around 50%, the battery drops to 15%. The weird part is that while I continue to use the phone, it slowly rises back up to sometimes 30% and then starts going back down. I've always cleared battery stats when flashing and calibrated (which I believe is unnecessary), but I don't know if this is a problem with the battery, the phone, or if anyone else is having the same issue?
Attached is a screenshot of battery usage. You can see I never actually charged the phone.

anyway guys, you need to recalibrate your battery, its not being read accuracy.
download BatteryCalibration from the market, charge your phone till 100% (not just 100% but when it beeps, that its truely at 100%), then use BatteryCalibration to calibrate your battery, and then drain it to 0.. (crank full brightness, turn on LED flashlight, blast internet radio, whatever makes it drain faster to get this part overwith), then recharge it to max.
so;
charge to full 100%
while still plugged in, run BatteryCalibration
discharge to 0%
recharge to 100%
battery successfully calibrated, you will now have an accurate reading
I had exactly the same issue on 3 different custom roms....finally resolved by going bck to stock rom

Sorry guys, but your method with BatteryCalibration is useless ....
If you wanna do a correct calibration, look at here http://forum.xda-developers.com/showthread.php?t=1312273
Cheers
Put back the battery on the right side.
8. Turn on the phone.
9. Pray the Battery god
And that post is just nonsense based on the old battery bump method .

The topic pretty much explains it. I've been using different modified stock roms and now I'm on the latest nightly of CM7, and I keep having this issue. After a reboot at around 50%, the battery drops to 15%. The weird part is that while I continue to use the phone, it slowly rises back up to sometimes 30% and then starts going back down. I've always cleared battery stats when flashing and calibrated (which I believe is unnecessary), but I don't know if this is a problem with the battery, the phone, or if anyone else is having the same issue?
Attached is a screenshot of battery usage. You can see I never actually charged the phone.

i have the same problem when i use custom roms.
i have been using pure stock rom by wannam but rooted for the past week with 12 hours aday syncing and surfing the net and plenty of voice calls via viber and my battery lasts at least 16 to 18 hours.
right now i am using odexed KL3 Kernel KL2Base KL1modem 2.3.6 and it is absolutely amazing interms of battery life and performance.

Maybe, you wanna share a better way to all of us ?
Are you using speeded kernel. If you are then it is because logging and debugging is off.

Got the same here, very strange, on CM7
Sent from my GT-I9100 using XDA App
This thing only happens on CM7 for me. It had 40% before reboot and like 15% after. However mine only increased to about 17% then started dropping as usual. This never happened on any stock ROMs I've tried(stock, not themed/modded stock).

did you
did you rsolve the problem ? how? I have the same problem and I tried more stock roms ... I don't know what tot do ....
Its nothing to do with calibration etc, its just how the fuel gauge chip works, it learns and more accurately reports usage over time. For example, if you reboot and (I can't remember the actual voltages for the S2) you have 1200mV, the chip goes, "ah, that is 15% battery." Then as you use it more, it relearns its settings and goes "aaah, my mistake 1200mV is really 30% battery. I'll display that instead."
Its been covered frequently that "calibrating" the battery of the S2 in any way but actually using it, is next to useless.

I'm having this problem too, what did you all do besides get new phones?
Got the same here, after update stock jellybean
Had this problem, when my S2 was half a year old.
I got the original Extended Battery and that solved this issue completely.
The replacement Battery has held up since 2013

anyway guys, you need to recalibrate your battery, its not being read accuracy.
download BatteryCalibration from the market, charge your phone till 100% (not just 100% but when it beeps, that its truely at 100%), then use BatteryCalibration to calibrate your battery, and then drain it to 0.. (crank full brightness, turn on LED flashlight, blast internet radio, whatever makes it drain faster to get this part overwith), then recharge it to max.
so;
charge to full 100%
while still plugged in, run BatteryCalibration
discharge to 0%
recharge to 100%
battery successfully calibrated, you will now have an accurate reading

did it but it still there... phone flicks and goes off at or below 40% wont turn on again:crying:
same here and I got the 2000 mAh samsung battery back in the days but now it happens with both of them also when my phone shuts off the screen brightness start flashing weirdly
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.

Do a clean install with Odin?

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.
I have this habit of doing clean install. No mistake with that.

With normal usage it is more than 10 hours at 77%. May be it's normal but it last more than that on 4.1.2

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.

If I browse the internet non-stop from 100% batttery then, after around 3 hours the battery is 20-30%. Is this also normal.
Maybe your battery is damaged ...
otherwise you can check for wakelocks using Better Battery Stats:

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.

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

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.
