[INVESTIGATION] Battery drain bug in 2.3.4 (JVP build for now)

It seems that our beloved Samsung did it again!
Now we can enjoy a fully functional, long waited, Gingerbread 2.3.4.
Although some sources say that it is only a leak, the JVP build seems to behave really well, according to the reports of many users.
Gingerbread 2.3.4 was build in order to fix some Android bugs and make the interface even faster. We have seen that the second task is a success, the user experience and crazy Quadrant scores being the best witnesses. But what about the first task, are there any android bugs in this build? Maybe we could find out together.
The key purpose of this thread is to find out if that Android OS bug, which made Gingerbread users a hard life, is still present.
You can help this investigation by keeping an eye on the battery stats and reporting the consumption (in percents, of course) of the Android OS. It is even better if you can add some screenshots.
Please don't forget to mention:
- The ROM and kernel you are using.
- Some apps or games you are using (known to fire this bug on previous builds).
- Whether you have autorotation on or off (some users reported they had no drain if kept off on 2.3.3 builds).
- What type of usage you applied to the phone (not really necessary, only you are kind enough).
If you have any kind of suggestion regarding some modifications for this thread you are welcomed to post them. It will helps us become more efficient.
Thank you very much for your effort!
EARLY CONCLUSIONS*:
- Battery life is indeed an improvement on JVP 2.3.4
- The Android OS bug is less aggressive. The reports show a maximum consumption of approx. 20%. We can't say for sure if we can talk about a bug anymore. Anyway, the drainage is not so bad, comparing to 2.3.3 versions.
- The Android System consumption is a bit scary (15-20%) especially after a flash. However, it tends to stabilize in time.
- A clean flash, factory resets, avoiding apps restoration with Titanium or similar, reducing consumers when you don't need them always helps. With or without battery draining bugs.
- JVP is a better alternative for previous versions due to improvements for battery life, speed and stability, even if it's a beta release. So you should go for it, it really is an upgrade!
*The statements above are based on reports and poll results collected until now and they may change. I take no responsibility if you will find those informations incorrect or incomplete. Flash JVP at your own risk, you could loose data or brick your phone, although there aren't reports that say that. Follow the instructions and you should be ok!

is this a new craze insted of train spotting or stamp colecting ....battery watching ....most of us have got a life and have better things to do then watch how much a battery uses ...do what i do charge the phone and enjoy these phones do use loads of battery

Updated with 2.3.4 I9000XXJVP,CSC = I9000OXAJVP and kept it on without sim and without even touching but fully charged. The battery life was just for one and half days.

Android OS running at 3%
using Damian's GTO Alpha kernel for JVP and Brotuck's gingerMod ROM.
Autorotation off.
Consistent q scores in the 2600 range, phone running very smoothly and very fast in daily use (internet, twitter, pics, camera, messaging, phone), 130+ apps installed, no issues. Seems a much better base firmware than any of the 2.3.3 variants.

It's a bit early to investigate this stuff.
Wait for Samsung to release 2.3.4 sources and devs to make some stable kernels based on this.
Until this time many stuff can be broken (well, you're free to beta test though ).

batery is much beter in 2.3.4

no since i flash JVP 2days ago!

Keep in mind that after a reflash the battery life will stabilize after a while.
In my opinion, the cell standby may be the cause. If left without SIM, Airplane mode off, your phone will continue to search for signal and this really drains the battery.
If you can make a test again, check the battery usage and post your conclusion.
Thanks for your contribution!

This kind of activity is normal in community, especially here in XDA.
It will be useful for those kind of people who don't like to experiment in order to find some answers.
We could do like you but, what if we need to charge it again, after 8 hours, without using the phone?
That's why this "new craze" exists, because we want to avoid that kind of problems.

You're right but the 2.3.4 concentrates on fixing bugs, so even in beta stage we should see some changes.
Anyway, the thread is intended to test the firmware regarding this problem, so it can become an indicator for people asking weather they will experience this problem of they can enjoy using their phone without even thinking about this.

Thanks for your feedback, happy user!

I must say that 2.3.4 battery is performing better than 2.3.3 so far.
After 11 hours with gps and auto rotate on, battery still have 30% of juice left.

Comming from Froyo JPY to stock deodexed JVP, I have noticed a higher battery drain.
I lost 13% overnight, I had 21% battery use on cell standby (6hours of use). and I noticed something very strange, android system has a 18% battery use with only 5 minutes running, WTF???
I'm using stock deodexed rom from ramad, Dark core kernel and screen off animation. that's all I've changed to this rom, no games, and a few apps like titanium backup and atk.
When I tapped on the android system there was a huge list of included packages, I will list them here, maybe one of them (or all together) is causing that huge battery use:
com.samsung.InputEventApp
Service mode
Software update
Google Backup Transport (actually, I turned off google backup, idk why this is here)
Settings Storage
Mobile tracker
Account and Sync Settings
EncryptApp
Task manager

It seems that you have a normal consumption on Android System. Also that app list is present on every ROM which has all system apps. On lite ROMs you can get a smaller list, because some of those apps are removed by the chefs.
Maybe your network coverage is not that good
After a flash, the battery needs stabilization, until then it can drain fast. Try to recalibrate it. Please tell me if you need a good guide.
Try a lite ROM. Maybe you will experience a good Android System consumption.
Thanks for the feedback!

Look at the poll results so far 72% say they have no battery issue, so it must be the apps on your phone that are at fault for any unusual battery drain.
Look at your own apps first before you blame the rom, mostly it's not the rom that's at fault.

When you're not really using your phone, Android System will have a higher battery use percentage, because nothing else is using battery.
Long periods of idle, you will see higher Cell Stanby and Android System percentages.
The more you use the phone, those percentages will lower.

Good job! Enjoy your phone!

turn off data connection or wifi when youre not using them
and it will least even longer...

This is what i had with the previous JVO (2.3.3) and not using any task killer anymore. I moderately used the phone, made some calls, wrote some SMS, had blutooth on in the car, listening mp3. Ah, and i set display brightness to "auto" always, i don't use the manual setting with lowest brightness value anymore.
But i also can get the battery down in less than a day...
I'll give the new 2.3.4 a try.

It's funny to see that there is always somebody who needs to torture the board with reinventing the battery wheel. Strange battery behavior usually shows up (and is often dependent on them) in threads with special roms or kernels. The only thing this thread will brings us is more of the same on how to save juice if you don't want to fork for a larger/extra battery.

galaxy SII battery usage

i bought my galaxy SII 1 week back and im not much happy with my battery consumption ...its average but from two days i dont know why but the Android OS consumption usage is increasing.....can any1 plzz xplain me what to do and if i do rooting will it help with the android OS issue in battery
im attaching my screen shots...

Moved thread here, where it belongs.
This high Android usage seems to have gone in newer unoficial SGS2 builds.
Rooting and flashing a ROM based on anything Post KF2 might resolve this after a full Wipe of device.
(Full Wipe Then Flash new Rom)

that is built into android now.
menu > settings > applications > battery.
If you click the graph at the top of the page you get more info too.
as for the OP, the easiest way to gain battery life is to get a good custom rom, and also underclock!! (even if its just for screen off). Most of us at VillainRom have underclocked to 800mhz and you honestly cannot tell the difference you can easily get 24 full hours of heavy use out of it.

yeah, updating the official stock rom would help or just get litening rom 1.5, few people complain about battery drain there cause thats definitely what you've got, most of my battery usage is from display and i only last 12 hrs cause i use it so much

This worked for me:
Root.
Backup, then uninstall certain systemapps with Titanium backup pro.
Advanced task killer pro.
Much better battery life after i did this

The percentage given for android OS is the percentage out of the total battery usage. If you don't use your phone, then android OS will be the one consuming the largest proportion since the operating system still runs while the screen is off.

I was using an app to get the same graph, i guess that way will consume less battery when i check it, as it doesnt have to run any app...=)
Thanks too for the 800mhz advise!

thanks for the reply im totally new to this android amateur....so can any 1 have a guide for the step by step process...so how should i install this villian rom...im guessing rom means operating system right....so rooting also include in it.........

From my finding, disable following features can totally kill the "Wifi Sharing" service and help battery performance a lot.
Accuweather Widget (preloaded on GS2)
Uncheck Settings -> Enable current location
Voice Command & Voice Talk (preloaded on GS2)
Uncheck Settings -> Use location

hi thanks for ur advice ..after installing villain rom i dont know why but still Android OS is consuming a lot of battery so can you plz help me out to fix this probs...and one of the thing i observed i s camera shutter sound is off which is nice....but do u know how to on it.....and do u know how to use the camera app even ur battery <15% bcz when ur battery is at 14% SII doent allow to use it....

Galaxy Note 2.3.5 high Android OS Battery Use

My galaxy note is constantly displaying Android OS use between 50-70%.
Anyone else experiencing this issue?

Flash a Custom Kernel based on 2.6.35.14 (2 are available). This solves the problem.

thanx for the suggestion.
But i'd rather keep the stock firmware, for now, as this is my first android..don't wanna risk a brick.
From other threads i've read, there's a newer firmware 2.3.6 available for the germany galaxy notes. Any idea if it fixes this bug...its really annoying..i've already done factory resets thinking it may fix it .

I bought my note in st Louis USA . It had european charger and strange language that I don't recognize . it came as KJ4 build . So I don't know from what european country my note came but I downloaded and flashed Hong Kong rom 2.3.6 and its pretty good with battery , wifi , etc . I am just really disappointed with camera . My battery usage for android OS = 8% and Android system 7% . This link might help you . http://leemn.wordpress.com/2011/11/13/rooting-and-installing-cwm-for-the-samsung-galaxy-note/

It definitely fixes it on the German Note... at least mine

I had/have the same issue. I flashed the latest KKA ROM which flahes the KK5 modem. I deodexed it and turned off some unwanted system apps. Running the CF-Root KKA kernel and Android OS spikes to about 30-40% at times. I don't think it really has much affect on battery life. From what I understand and have read, it has to do with wifi Scanning repeatedly. You can adjust your wifi sleep policy to help this.

If it's keeping your phone 'awake' then you should install BetterBatteryStats which monitors Wakelocks. It'll tell you what OS services are going nuts.
It's happened to me a few times with rogue programs and USB host going crazy when I don't unmount correctly.

Same thing happening to me? Do you experience heavier drain on wifi than 3g?

Any misbehaving program either got their settings adjusted (stuff like sync frequency) or uninstalled. The USB host issue was, I think, because I unplugged the USB host cable without unmounting first. I just rebooted my phone in that case.

Well after countless number of hard resets....Android OS use in now around 11 %...
the difference i think was because of some apps....i'm not really sure...but this time i didn't install skype, winamp and viber...cuz every time i installed em...Android OS would be like upto 90%...

I currently have 2.6.35.7 with the KK1
would it be safe to update to the 2.6.35.14?
high OS battery is my only real problem.

I have the same kernel but with kk3....dunno if 2.6.35.14 will help with Android OS battery usage...my note still has no update available....
The only thing i can suggest for now its most definitely an app you installed which is causing high android OS usage...read my previous post....i hard reset my note installed all apps i had before but not winamp, skype and viber....i've kinda narrowed it down to these 3 after many hard-resets...
When i had them installed....my phone lost about 2% battery per hour on standby....But now it loses 1-2% in 8 hours on standby...

I'm having the same this with the high OS battery drain and have skype installed. Going to remove it and see if I get the same result. I didn't have the other two.
I've got the 2.3.6 KKA firmware installed but the drain just suddenly started one time (not when I installed it). I figured it can't have been the firmware itself, but much more likely an application I had installed or had updated.
Doesn't ICS have a better breakdown of service usage etc? Should be perfect if they have done this. Just have to wait and wait and wait for the ICS version.
Surely there is an app out there that can tell you what in the "Android OS" is causing the problem?
As an indication of how bad mine is at the moment, I was 100% at 9am this morning, 11:30am now and its down to 84%.. That's really awful!
I want to reset the battery stats as it could simply be that, but don't have CWM installed on this firmware. I'm rooted though.
[update] I've removed the battery stats file and restarted to see if that will help too.

Yea...let us know if removing skype helps....
oh and i installed Asphalt 6 from the samsung apps store.....its not available in the market....i had also installed it before hard resetting my note.......and guess what....high Android OS usage again.....damn....removed it....and i think its back to normal....but still have to see if removing fixes it for sure......

I guess the battery manager will count power used by all hidden processes and services as Android OS...

I had exactly the same experience with Asphalt 6 too. Good game, but why it sucked so much power when not even in use, hell knows!
Skype not made a big difference that I could tell, but resetting the battery stats made an immediate difference. 2 hours since charged and only down to 98%. Usually it would be 90-92% by now.

How do you reset battery stats

Same Boat
Hii,
Following are my stats
Android OS at 35% (Awake Time 1 hr 36 mins)
Display at 25% (on for 3 hrs @ 12% brightness)
Voice Calls at 13% (34 mins)
I don't know if the Android OS is a bit of a drain. Feels so. I think the Wifi Sharing and Wifi always remain on. So does Social Hub - use it to sync FB pictures to contacts as Social Hub offers great quality pictures unlike FB app or Friendcaster.
I do have Skype installed, but its never been initialised, never logged into.
I use GO Launcher, with 9 home screens. TouchWiz has been rendered empty (no widgets, short-cuts whatsoever running there)
I do use APW widget pack - Twitter & FB updates at 3 hours. GReader (with Google Reader syncing every hour). 2 Contacts widgets.
In addition to it, I also have the PowerAmp 4x2 music widget. Homescreen has Simple Calender widget, A "Make youw own clock" widget, a 1x1 Beautiful Widget Weather.
Dunno if the widgets are causing the drain or not.
Like you remarked, my battery drain ATM is around 1-1.5% per hour, with Wifi On and everything running and syncing (as above)
The standby time has been pretty decent. Whereas I am happy with charging everyday, if I could reduce the AndroidOS overload, I cud brighten up my screen a bit more
Dunno wat to do now. I don't wanna root now or try any techy stunts. The phone is only 2 days old yet.
Wud appreciate if anyone can guide me around. I will try to FORCE STOP the Wifi Sharing and Wifi Sharing manager, along with Social Hub, and EMail apps/services tomorrow.
Wud be amazing to lose 2% over 8 hours on standby. Awesome.

[Q] TWO Android systems draining battery??

Good day to you all,
Recently after a small android update (still having version 4.4.2) I noticed the battery was draining faster than I'm used to. Before that, it was consuming roughly 1% per hour in idle. This has changed now to 3-5% per hour. Looking at the battery info I noticed the Android system was the biggest batterysucker here. Not only that, there are even TWO Android systems shown and I began to think there's something wrong here.
http://forum.xda-developers.com/attachment.php?attachmentid=2908920&stc=1&d=1408796626
Also looking at the wakelocks shows that my phone is barely able to get into sleepmode.
http://forum.xda-developers.com/attachment.php?attachmentid=2908921&stc=1&d=1408796626
Before posting this thread I have literally tried every option to see if it could lessen the battery consumption:
- Disabled Google location reporting services
- Disabled GPS
- Disabled Google sync
- Disable Wifi when in Sleep mode
- I don't use Google Now so it's disabled
- Widen the Facebook refresh intervals to 4 hours
- Wiped the cache partition
None of the above worked and I started to think that the second Android system here might be the cause.
Should there be a second Android system consuming battery? What could be the problem here??

Will this app also show the needed info even when my phone isn't rooted? Because I'm really not into rooting it.

Hi mate
This is from the thread :
Q:Why installing BBS as a system app as everything works with root?
A: Starting with Kikat BBS has 3 modes: without root a limited mode provides a minimal set of stats. With root the set of stats is complete but some stats (other, partial wakelocks, processes) still use a workaround. Finally with the system app BBS is fully featured without any workaround.
For this cases root is good to have as it gives you a better access to all the process running , try without root and see what kind of info you get

If it's a conciliation, my android (currently on AOSP) is also running two android systems. Not exactly the same name (Android-System and Android-Besturingssysteem), but you get the idea. You mentioned quite a few things you've already tried, but what about existing widgets and or android apps you've installed? Usually (for me anyway) battery drain is an installed app not exactly behaving nicely.

Hi mate
This is from the thread :
Q:Why installing BBS as a system app as everything works with root?
A: Starting with Kikat BBS has 3 modes: without root a limited mode provides a minimal set of stats. With root the set of stats is complete but some stats (other, partial wakelocks, processes) still use a workaround. Finally with the system app BBS is fully featured without any workaround.
For this cases root is good to have as it gives you a better access to all the process running , try without root and see what kind of info you get

So does this mean I'm not able to see the exact cause of my wakelocks since my phone isn't rooted?? I have installed Gsam Battery monitor from Google Play, hopefully it will give me (and you guys) the relevant information after keeping my phone on idle for a while.
@Skyrider: The weird thing is that in my case, it DOES display the same name twice. Doesn't that seem weird? I can't see any Android OS (besturingssysteem) displayed.
Also, if I have a battery heavy app, shouldn't it be displayed in the battery info screen as well? I only have the Weather widget and a News widget (NU.nl) on my homescreens. Haven't installed many apps except for Facebook and a few games that barely use background processes.

In my opinion, that's the problem with the default battery information. In my years of experience, it usually never knows the information that you need what exactly is braining the battery. If your battery is still being drained, I suggest to remove most of your apps. Only for a day orso. It should be enough to gather the information to know that at least one of your apps was the cause of it.
It's a pain to do it. But It always has helped me rather than relying on apps of which usually doesn't work out for me.
Also. Might be a good idea to alter your system language from Dutch to English and check the battery info again to search for the duplicate running system on google. You'd expect "Android System" being enough, but who knows that a different language might show a different name.

Ok, I don't have the slightest idea what happened but my battery duration is amazing now. After installing Gsam Battery Monitor and charging my phone to 100% I went to sleep and after 10 hours of standby I looked at my phone and it was on 93%. My phone doesn't consume more than 0,6-1,0% per hour now in the last 3 days!!
I haven't changed anything except choosing to use Wifi and mobile network for location services but not GPS. Weird thing is that I tried that option before without success.
I'm happy now
I'm still confused about the 2 Android systems in my battery info screen though. That might be a good idea to try @Skyrider but I do remember that "Android OS" was displayed differently in Dutch a while back. I'm guessing you have your phone language in Dutch as well since you're seeing "Android Besturingssysteem" on the battery info screen?

Yea, I'm using the Dutch language. But I'm not using the stock ROM of the phone, so hence I am seeing different systems running in the background. But I'm glad the battery is semi-fixed.

Ok, so I changed my phone to English and behold, one of the "Android Systems" indeed changed to "Android OS"
I could have sworn it was like that when my phone was in Dutch.
Perhaps someone with the stock ROM in Dutch could check that out?

No idea if this helps but i thought might as well contribute what it sais on my phone
Edit : i have a very high idle battery drain so any advice is welcome btw

Thanks a lot for confirming this! I guess Android OS is indeed translated to "System" for Dutch S4's.
Have you tried my suggestions in the opening post?

I've been running back and forth between tweaked rom with shinto, and this (been testing kernel for CekMTL...) and whole on Temasek's Roms I haven't had any battery drain problems, overall it's been a great rom... Last full cycle I ran was on 5.7...sm900t, and I got over 30 hrs. With 8.5 SOT... Now I make a lot of tweaks to get my life... I use Blue Mail, cause it use GCM for delivery... No syncing on all the time, textra for sms, dolphin browser, Nova launcher, I have way too many app to list them all. I always run the intellimm gov, with row schedulers set at 1024 Read-aheads
Common sense isn't all that common

WiFi always on, GPS and sync off unless needed, I also use greenify and lux auto brightness.

TIA

On my phone, the screen is still the top battery user. And I've been using CM12 for quite a while.

Thanks for your answer. Look at this screenshot. Anytime "Mobile radio active" ("Cellule GSM active" in French) for an app is longer than screen on time, then this app is higher than Screen in battery report.
I still cannot get KitKat battery. Lollipop is hungrier for me, even when sleeping it does drain a little.

I'm on Wi-Fi must of the time. I do know that a poor mobile network connection drains the battery faster than a good connection and that Wi-Fi is the least battery draining.
So I'm wondering if you are not on Wi-Fi and live in a poor network connection area.
