CASE CLOSED!!! Please read bottom part or flash stock GB 2.3.4!
I have posted this already on another thread (almost word for word) but I just really want you guys know and not panic about this problem and avoid going through difficult fixes like deleting system apps, recalibrating battery or even resetting your phone.
Since JVK was released, many observed that Android OS sometimes get hungry and devours battery. For some reason it is triggered to go berserk. Others say that the main culprit is the Auto update app. But other apps like Google Maps, Latitude and even just in a place where there is very low network signal or Wifi reception could also trigger this problem.
Now, I have a very simple solution: Turn off device, remove battery for a minute, put it back then turn it ON. Yes it is just that simple, REBOOT YOUR DEVICE.
Yeah after you turn on your device Android OS is still on the top of the list with high percentage but I believe it is just as it is because it previously consumed a lot of battery. All you have to do is observe again for an hour if your battery is dropping again, look into the graph and see if it is still steeping to the bottom. If it is dropping like Mt Everest, do the procedure above again.
If not, you will observe that after a couple of hours Android OS's percentage is getting low. Problem is fixed, (temporarily though).
Why go through deleting apps, recalibrate battery etc when you could just turn off your device for a minute?
I have experienced it a lot of times already (one of the first users who upgraded to JVK) but it doesn't bother me anymore. Turning off then on your device is very simple ain't it?
I highly advise that you do not touch anything on the sensitive part of your phone as there is no known single root of this problem. Just like I told you, many situations or apps could trigger Android OS to go berserk. Until there is no definite solution to this problem, I suggest you do the above procedure and save yourself from going through the pain of removing system apps, battery calibration or even hard reset.
By the way my battery usually lasts 3-4 days unless I made Android OS angry again.
INVESTIGATION
INVESTIGATION CLOSED!!! The culprit is caught. But the fix is not so simple. Only Samsung and genius devs (apparently the fix requires closed source modification) could fix this. If the problem occurs on your device, just do the temporary fix above. Please do not try to mess with your device for now.It is now fixed in XXJVP 2.3.4!
Click HERE and read the bottom part for more details.
All this is due to Tatsuya who pointed us to the right direction. A big thanks to him for helping us in this investigation. CASE CLOSED

Ok thanks for the credits.
This previous link I gave explains how you can use watchdog to alert you when this bug triggers, so you know when to reboot your phone to stop this leakage (if you really want to stay on gingerbread until a fix is made by Samsung).

Guys if you want to help out please please please dial this *#*#4636#*#* and check "Usage Statistics" and let us know the top 3 items on the list! (highly suggested by {Angel}).
Below are some of the possible culprits currently pointed out by some users (I will update the list based from your feedback):
1. Software Update service
2. Google Maps
3. Latitude
4. Low network signal
5. Very low WIFI reception
6. Auto updates in Market
If this helps, a simple thanks is enough

Those of you with high drain, you can also check battery history through *#*#4636#*#* and see what you have under other usage 'running' and see if your phone as not been sleeping lately. I get this occasionaly with froyo and I suspect many people do also. A reboot fixes it for me, after that my battery usage is superb, but it's annoying as hell.

Yes just like I said in the first post, this is just a temporary fix. But I think users should just do this rather than touch anything on their phone unless they really know the source of the problem.
That is why I suggested that they report what could be the possible triggers, like apps or situations, that make Android OS to awake and gobble up the battery. If we could just pinpoint those triggers maybe we can now figure out the root of the problem. Your fix of removing a system app, the auto update app, is not even the single source of the problem. We just do not know if that app is an essential app or not. Sooner or later you will have that problem again.
I am not saying we should just sit and wait. All I am saying is if you are a plain user and you do not know the exact root of the problem, then just do what I suggested. But if you are a dev and is exploring the root of the problem, then do as you like and we will be most thankful if you find out the answer.
People are mislead about what works and what is not. I just want to help.

Rebooting works, and it seems to be working until you start some apps again. I have the same apps installed as I had on JPY, but JVB drains my battery dead in half a day.

Could you pinpoint some apps? I will update the OP to keep track of possible culprits so that others will avoid triggering this problem. Thanks!
I once saw that the battery drain from 95% to 9% after one night, and the android os used most of it. I rebooted my phone, and the problem has gone away, since. Happy with Gingerbread!
I'll give it a go! thnx
Active Widgets: WeatherBug Elite, 3G Watchdog, BatStat and Calendar.
Apps: All from above plus Twitter, Titanium Backup, Facebook, Twitter, Tapatalk, Camera360 Ultimate, Root Explorer, Foursquare.
Mostly I use the Twitter client and the browser. Location services are disabled.
It is hard to figure out from the above apps or which is the most probable suspect. Just incase the problem recurs on your phone, dial this: *#*#4636#*#*, Go to Usage statistics and Battery Information and please report back (include also information on the Battery Use in Settings).
I hope we can help others avoid having this problem until there is a fixed solution.
Thanks!
Did what you suggested and pulled the battery at 30% waited 5 minutes and put it back in.... 1hr later it was at 35% (WTF!) and 30min later it was at 38% (WTF!)
im assuming its recalibrating?
Not necessarily. Maybe the battery meter is anticipating the fast consumption rate of Android OS that is why when it got fixed, the meter is able to readjust the readings based from the current consumption rate of your phone. Good to know it helped
Maybe use the 'forbidden' task killer? Works for me... Maybe im imagening it but works.
Btw my battery goes quickly down after getting below 25%. My battery not calibrated? Should i.calibrate it? I have this program to do it but am afraid that calibration goes wrong. (example what if my battery is 95% and will calibrate to 100. What if.i charge my battery higher than this.. Will it show 104%? Or will android stop working for it cannot be displayed in the notificationbar.

You do not have to recalibrate. Cm7 has a known issue about battery. I think you cannot charge past 94 or 95 percent and battery usage is a bit terrible. Please refer to cm7 thread for possible fixes, (the last time I checked their thread, they say it is probably kernel related).
Just turning off, pulling the battery and turning on does do a lot for me! i went from 10% per hour to only 1%! great thnx!
Hi,
About battery drain in gb, once fixed the wifi sleep policy issue ( by setting it to "never") u shouldn't have batt drain, but i've installed green power ( juice defender do the work too i think) to get some wifi management possibility back and it improuved my batt life.
But never the less, my battery won't last more than one day of hard usage ( being hanged on xda all day long, for instance ;-)

Guys, just turn off the task killer, it helped in my case. looks like its not working well on ginger
Rebooting works just temporarily.
It will come back the next day or so.
This is not a solution at all tbh.

Guys, on Gingerbread I've had battery drain two times:
1. Had about 14% drain in 3 hours all of a sudden, without doing anything at all. Just started going down for some reason.
2. This morning, saw about 40% drain in 7 hours..
And, both time I solved it by Clearing Memory from the Task Manager.. Went back to normal 2-3% drain per 6-7 hours after that..
So this might also be a solution. Go to Task Manager, RAM tab, and Clear Memory..
i'm on ginger also and my battery acts weird. 2 days ago i charged my phone over night while it was closed. the battery holds for 15 hours with massive use.
last night i did it again, but today it went from 98% to 80% in about an hour !
this is really weird.

Did you manage to check first what is running on your device by looking into Battery Usage settings? I think you have a case of rogue application running in the background.
If you have not rebooted yet could you please attach a screenshot of the battery usage list and graph? In that way we might possibly identify the app running prior to the clearing of memory. Thanks!
Normally, after work, my battery would be around 85%, but all of a sudden, yesterday, my battery after work was only 24%. I am not sure what is the cause of this behavior. I installed apps like tripit, travelsafe, skyscanner, onthefly, but I don't think that should cause this.
I have tried the battery removal trick, but it hasn't worked. The phone wakes up every few minutes and therefore, drains a lot of battery. Could someone offer good insight into what is causing this and how to solve this permanently? Thanks.

According to the tings I've read, you should always unlock the screen before removing the charger and if the problem persists just do a reboot.
That's what always works for me - on Speedmod kernel.
I'm on sppedmod kernel and sometimes will not go into deep sleep...phone will get very hot in my pdocket which to me is a sign that its not going into deep sleep. ill then do a reboot and monitor thru cpuspy. reboot works but I've not found a permanent solution as yet.

Thanks for your replies, but unfortunately, rebooting hasn't worked for me.
What else can I do? Please do not suggest formatting or wiping anything, as it would be too much of a pain to do with my current configuration.
Perhaps you can try to - flash abyss 3.9 for GB - run that jbroid kernel cleaning - reflash your kernel.

Have you tried going to Airplane mode only? If you haven't done that, then try to see if you can turn your phone mode off and observe if your still getting the high battery drainer issue.
One of the big drainers in the battery are your high percentage screen output. If you got a high screen % output that means you got wakelocks and it's being triggered by an app/s on your phone.
See if you can disable one by one those apps you mentioned above, charge up your phone to say 10 to 15 mins, take out the charger, set screen timeout (on settings to 15 secs) and turn off the screen and set your phone to airplane mode off. Observe for an hour without using it.
Note the percentage on your Screen from the time you took out the charger to the time you check back (after an hour) to see if it had gone down already.
Cheers/
Hi,
ICS has this 200 MHz problem and, for the moment, there doesn't seem to be a lot to do about it. I reboot every morning after charging and I'm fine for the day.
Without getting paranoiac about your battery (you have your phone because you use/need it, not for becoming a world champion in Deep Sleep ), mind what you install.
I usually "lose" between 1~2% capacity/hour and manage to run it a whole day with ~60% of the battery (WiFi, BT and GPS active). Yesterday I installed some Security thing and jumped to 4~5% immediately. It also caused constant 200 MHz mode and reboot didn't change a thing.
I dumped it this morning and am fine again. Here's my situation after 3h48m of activity today, I have 88% left
(Sorry for the big picture but I don't manage otherwise )
I keep my GNote as standard as I can and just verify briefly, with CPU Spy if everything is fine after installation of a new App. If it's no good I delete it and that's it.
Thanks everyone for the replies. Without quoting everyone, let me say I have tried all the tests you guys suggested. I have tried the airplane method, rebooting, monitoeing for apps, etc. I dont have latitude so didn't try that method. I also reinstalled speedmod k3-3 kernel last night.
I upload there images: system battery info., cpuspy and betterbaterystats. It seems, for now, my phone IS doing a little better with going into deep sleep. Unfortunately, I don't know which method worked, so I don't have a definite solution for anyone suffering from the same issue. As an observation, my phone used to go into deep sleep mode much more than it does now.
Edit: I have attached the following five screenshots to be analyzed. It seems the issue is not solved yet, and the phone still doesn't go into deep sleep the way it should. Could someone help point out from the screenshots what's going on? Thanks.

In your screenshots you have WiFi running for a lengthy period.
WiFi is notorious for eating the Battery.
Only use it when you actually need it.
The only contradiction to this is when you are actually using WiFi for an extensive period (do not include turning off the screen and leaving WiFi running in this description) it is kinder on the Battery than a Data Plan.
Also, as jpmiv mentions.... don't just remove the Battery (which I note you have already tried this method) but again as jpmiv mentions leave the Battery out of your Note for a short while before reinserting. It will clear away any residual memory on the Note.

I put the phone last night into airplane mode, turned it off and charged it for several hours.I'll test how it works today and post the results. If it doesn't show any signs of improvement, I will try your recommended method.
For historical information, I did try removing the battery for more than 10 mins, but did not charge it while it was turned off after inserting the battery. As I said, I will try your method after some testing today.

It's definitely your WiFi which is the main culprit.
Look at the WiFi Running and wlan_rx_wake
Have you turn off your WIFI dude?
Judging on the screenshots you made... your WIFI has been ON for a lengthy of time and anyone knows that if you enable your WIFI, it's surely going to eat most of your battery.
Try to see if you turn it off, and see if there's a considerable on your phone's battery after.

Yes, wifi is on, but what I should have mentioned is that I used to have a much better deep sleep time even with wifi on before last Friday when the issue began showing up. Also note that the wifi was on only because I was home - when I am at work, I am on data connection.
Is there anything else in terms of apps that you find unusual or the cause of the issue? Something is waking up my Note more often than it used to.

Hi All,
For the last month I have major problem with battery life.
While the phone is NOT in use (like over night) it drains almost 10% per hour.
I didn't install any new APP. The ROM version is Samsung stock 4.3
I installed 2 Apps GSam Batter Monitor and Wakelock detector.
As you can see in the screen shots the Kernel is the major consumer (about 90%).
I will appreciate your help.

Thats realy bad... Disable all GAPS (except Gmail and Play Store), any unnecessary apps (Task killers, AV etc). Let the battery go down to 5%, turn off the phone and fully charge it. Try WakeLock detector if no improvement.

Back up your stuff and reflash the FW. I would suggest using KIES 3 and in Tools option Emergency Recovery. It will completely wipe your phone and flash latest FW. When finished, boot up phone but don't set up. Do hard reset (either via Menu or use the 3 key combo) and you should be ok...

Delete it. Its a bad app. Do only battery draining. No more Because android its not the same like windows
Or battery is old.
Either your battery is so old that it's just had it, or you have a serious issue somewhere.
Why has no one suggested the app 'Better Battery Stats'? Install that, charge the phone to full and when it's at 5% screenshot the stats and/or save them and come back and post them here.

then i used xposed name per app hacking to prevent app wakelock and it solved my problem..
Hi,
I already installed wakelock app.
Here is screen shots.
Please advice.
Thank you
Your wakelock is kernel related. It could be GPS, bluetooth, using the wrong governor...there are so many things that it could be that it's impossible to guess.
Use Better Battery Stats as has been suggested. It gives a much more in depth report of battery use.
Yeah,it's hard to guess when related to kernel...mine is related on app itself

Hello Experts,
My Battery is draining like crazy. I tried almost everything to figure out what is the issue but could not figure out. Below are the details I gathered from the things I tried.
My battery started draining almost 30 % overnight. Initially I thought it was due to the Unofficial Marshmallow Rom, I could see Wi-Fi to be cause of this drain. Hence I tried different Roms (Cyanogen Mod, PA, DarkObas, Sultan ROM, and stock Cyanogen OS ( Past 3 versions, including latest one). but the battery drain didn't stop.
So I decided to flash PA rom again, installed OpenGapps PICO (Only Google play service nothing else). I installed CPU spy and left it over night in Airplane mode. When I checked in the morning (after 7 hours) battery drain was of 25 %. This was surprising as nothing was running on my phone and only the minimum apps were installed. At this time, CPU spy showed no abnormal wake locks and was in Deep Sleep for almost 93% of the total time. The stock battery usage showed only Mobile Stand by and usage of 50 mAh.
Can you please help me figure out what is causing the battery drain.

Thank you for your reply.
Yes I already tried that. The strange thing is Battery drain is observed in Airplane mode also, while minimum apps installed(Stock apps with PA rom and Opengapps Pico package). Do you have any other suggestions.
It's really hard to judge what could be your issue, you can try different methods to find out who is the actual culprit.May be an app eating your battery or device might have nasty wakelocks,alarms etc or the battery itself would be damaged etc.
Anyways,Turn off ambient display, install BetterBatteryStats then run a full cycle and analyze entire stats of your battery, you'll get know the issue or at least a clue. If you couldn't find out the issue after BetterBatteryStats test then clean flash the a ROM(Recommends CandySix or Darkobas ) w/o GApp and give it a try
Firmware
Try a different firmware version. Here's a link :
http://forum.xda-developers.com/oneplus-one/general/firmware-modem-oneplus-one-lollipop-t3300907
Sounds like your battery cannot hold its charge anymore.
How old is your OPO? May be your battery life is about to over.
And this battery drain suddenly started or gradually increased?
Try diagnosing by changing the Location settings to device only. It's some weird bug with COS and CM that's making it to the latest builds of 6.0.1 . I saw that older builds in May don't have this problem.

Unfortunately, Problem still exists even with the Brand New battery. Can any hardware issue cause this issue? It's certainly not Battery problem and not software problem as well.

You really should have taken my advice earlier and diagnose before making any decisions. If your battery truly was dying, then apps like 3C and Geekbench's battery test would've picked this up as they've linear-regression curve data from aggregate sources that you could've compared to. In your OP, you stated that you saw WiFi as a culprit, but did you also know that Google Play Services (depending on version) can do location requests up to 78 times within the hour on stock apps alone? I used to have this similar battery issue, but that was related to location-requests from Google Play Services that somehow propagated to other sources based on CM13's July commit, meaning that kernels also based on this could've been affected as well. What I eventually settled for, in the meantime, is using SultanXDA's 08082016 build and so far everything looks good on Wifi regarding what I expect for typical battery performance. If I learn something, I'll come back to report on it.

Have not tried any Lollipop Rom since the issue started.

I did took your advice and checked Location services. The problem occurs even with Wi-fi, 3G and Location desiabled. Also in Airplane mode with almost nothing installed (only gapps PICO package and CPUSpy)
i suggest trying old version it may help

You might wanna try that. Possibly MM eating through. I still use Lollipop too. I find no need for MM yet. Also MM feels anti-dev to me for some reason :/ Needs all workarounds for things that were previously much easy to do. Oh well. Try Lollipop and see if it helps? It'd have been my first step for troubleshooting before buying a new battery

Yesterday, I left my phone in Recovery mode (TWRP 3.0.2.0). In less then 5 hours, I observed battery drain of 20%. Same amount of drain is observed when running MM rom. I don't think changing to Lollipop will help. To me it looks like some hardware issue, can any hardware beside battery cause such issue?
Android system is using lot of battery more than screen. It's not optimised well. any fixes?
Same here. And I did a factory reset after updating to Oreo... High android system battery drain, I wonder what happened? Hopefully we got a fix soon.
Same here even after factory resetting android system draining most of the battery.
Is it really draining or do you only see it in stats? To be honest I stopped checking detailed battery stats, looking at discharging rate chart + idle battery drain (when the screen is off) are usually enough to say if there is a problem. Battery usage chart should be almost flat when you don't use your phone, Oreo has quite strong and fast doze mode.
Make sure it's really draining because Bluetooth shows me 12000+mAh spent with 80% battery left so obviously a bug in the charts not in the system itself. (Same goes for RCS)
Same here. I have RCS first in battery consumption then the screen. With nougat the chart of the battery had flat zones. With Oreo the chart is always descending even when not using the phone
We must wait for the january update, i think it will be fixed

same issue with me. I have not checked for the January patch yet. I am rooted via magisk, lovin' the gcam in mi a1.
the bluetooth battery drain issue is the only problem in my unit so far.
I too had the system battery drain problem.I solved it by removing my SD card and disabling "backup" in setting menu.
I got the same problem after updating to the January patch.
I read that the "APP preview messages" in Google options can be the problem, so i am checking this out with and without the option and look a the wakelock detector what it does.

DRAIN PROBLEM FIXED:
After some tests yesterday and over the night (while i was a sleep) with help of wakelock detector, i got my drain problem fixed by turning off the "APP preview messages" in Google options menu.
So try it maybe it works for you guys!
I've that option disabled by default...but great battery drain in standby

Damn, do you have wakelock detector lite installed? Just install it and keep it running for a couple of hours he will show you more information.
I've found that is that kernel wakeup: 7000000.ssusb that keep my phone alive also in standby...someone else with this problem? any solution? Thanks.

You can fix the standby battery drain by enabling "Data Saver"
Yes, I did say DATA, not battery saver
Go to settings and type "data saver" in the search box - switch it on.
I have stock OREO ROM, no fancy battery saving apps or custom kernel.
