This doesn't work. Ignore this thread please. Android OS and Wi-Fi Sharing reappeared after a few hours even though I was in bed sleeping and not using the phone.
For those who have problem with Android OS and Wi-Fi Sharing draining battery, this is for you.
I think I have found a solution. I need someone to try it out with me. So far so good. The main culprit is Kies Air. If you are not going to use it, please do not tap on that app at all. If you can, hide it. Once you tap it, it will remain running forever even if you shutdown and restart your phone. So what can we do?
First, Factory Reset the phone. Then, make sure you do not launch Kies Air after Factory Reset.
That's all. Now all you need to do is monitor the battery graph and let us all know your findings. You should not see Android OS, Android System high up in the list. Wi-Fi Sharing will no longer appear in the list that consumes battery.
I have success with this.
How long have you had it running like this?

why dont you just end the service in the settings?
I use Kies Air extensively. But it does not really keep running in the background here.
I dont keep my wifi on unless and until needed. SGS2 is very quick to get IP than my older phones, so i turn it on when needed from widget. Also you dont need wifi on before launching Kies Air. It will turn it on and off by itself.
when i close kies, it asks me if I want to disable wifi and it closes properly.
I tab of ATK and it closes on me never to turn back on by itself.
The only programs that keeps coming back are hubs and iplayer which to be honest does not seem to eat juice much. I will be getting rid of them soon enough.
now that i think of it the nexus one doesnt have kies air does it ? and it has the same android os issue?
Kies air shutdown wont help, did not even have it installed and still have android os bug
I've had both android os and wifi sharing eating battery, and I've never touched Kies. So it's not that.

not a soluton for me.. becuase i do occasionally use the wifi sharing so that i can tether over wifi.. the solution i am using which is kinda kludgy is to freeze the two wifi sharing apps with titanium backup (requires root).. works for me.. when i want to tether i will unfreeze them.. hopefully this will fix in a firmware update.
sorry guys I am late to the party.
WHAT AM I SUPPOSED to see for "Android OS" and "Android System"?
My phone right now is at 4 h 15 min (I charged it before going to bed, yes I sleep 4 hours a day). The phone did not do anything, but sounded Alarm to wake me up, and I had screen on for like 10 minutes total so far, plus the Alarm sounding and vibrating.
I have AOS at 37% up top, and AS at 3% on the bottom. This is not right?
I used Kies many times, but restarted the phone after the last time, and that was before the phone was charged last time.

my AOS is at 6% now - it was at 47% this morning... but i think that was because the screen was 0% whilst i was alseep, so yes your 37% is waaaay too high, mine was up at 15% but since i installed juice defender it has dropped to between 6-8%
Android OS / Android System percentages don't really matter that much - even if the device had a week long battery life, the percentages still have to add up to 100% - so something always has to be using battery.
The main problem seems to be the 'wifi sharing' and 'wifi sharing manager' services, which start up whenever you connect to wifi...

You mean you're connected to Kies Air and wanted to play with your phone while waiting for files being transfer? The answer is yes, press the home button and do whatever you want, it will not be disconnected.
Sorry, I meant when I finished and exit the program, something continues to run in the background (wifi share?) that drains the battery?
Damn...
Android OS @ 46% followed by Display at 21%. Android system however, at just 4%. Yeah 46 is just way too high...
Oh.. my watchdog didn't report any app misbehave after I done with Kies Air.
My wifi sharing will keep on running on background at 3% regardless of whether I connected to Kies or not. Frozen it but it still there. LOL. Weird.

This is my first android phone and I'm wondering if I am doing anything wrong. Yesterday I charged my phone and it was at 83%. I unplugged the phone and went to sleep, when I woke up this morning the battery was completely drained.
This happens a lot. Even if I am not doing anything it still drains like crazy. I just text, make some phone calls and it barely makes it through the day. I don't play any games, no gps, no Bluetooth or anything. With my plan, I don't have a data connection so I can't connect to 3g/4g so that shouldn't drain anything.
What could I be doing wrong? When I'm done using the phone I tap the power button on top, the screen goes black - to sleep I presume and I put it away. I had an iphone before this and I did exactly the same thing and the battery lasted for 3-4 days on one charge.
Whenever I see what's using up the battery, the display tops the list. The display is using up 75-80% of the battery. If the phone is asleep for most of the time why is the display using up that much battery? Am I not putting the phone to sleep correctly?

If you cant connect to 3g/4g, you should turn it off in settings. Otherwise, Your phone will constantly look for a signal, draining your battery.
Battery life is all relative. Every single person will experience different battery life. The apps you have installed, the amount of time you spend on it and the time you spend on/in each app, distance from cell towers, distance from Wi-Fi sources, settings you have for every app and things like sync and what not.
The first thing to check is if your phone is being affected by the init or suspend bugs. The good news is the former has an easy fix, and the latter can be temporarily fixed by a reboot.
First, download & install Watchdog Lite from the market. Then open its preferences and check "include phone processes," "monitor phone processes," and "display all phone processes." Then just use your phone as normal. It may take a while before you get an alert from Watchdog (and maybe you never will and it ends up you have a different problem). But if you do, note the process that is the culprit.
If it is the init process, go to settings>applications>development> check "usb debugging."
If it is the suspend process, reboot the phone. It should keep it from happening again for a while.
I know the second answer isn't really an answer, but so far it's all we've got for that problem. There is more information on the 2 problems in these threads:
Init:

Good luck...I had both of the problems and my phone didn't last to dinner time. Now I get better battery life than the iphone 3GS I had before this...about a day and a half of moderate use.
EDIT: also you'll probably want to go to settings>wireless & networks>uncheck "mobile network" since you don't have a data plan. No reason to have that on since you don't have a data plan.

I installed this using the Moderate setting, and then selected those options as recommended in preferences.
Does Watchdog use a lot of system resources when running in this manner? Will it cause the battery to drain noticeably faster?

Completely unnoticeable, IMO.
I installed watchdog lite and I have had couple of alerts. I got suspended couple of times and I also got Android system once.
Android system - 50.1%
Foreground
Suspend - 54.4%
Linux Process
I turned off the data usage from the settings and it did help save battery. The display is not using so much battery life anymore. It went from using 70% to 35%.
Edit: Battsatt reported that the battery was at 93%. When I saw the two alerts above I rebooted the phone and Battsatt now starts reporting the phone is fully charged.
Make sure the GPS is turned Off, too...

You just summed it up right there. You are experiencing the 'suspend' issue, period. There is no app you can install to fix it. There is no app you can uninstall to fix it. There is no setting you can adjust to fix it. There is no fix for the 'suspend' issue, literally.
I started the following thread in an attempt to consolidate posts and hopefully work toward flushing out what the real issue is...
http://forum.xda-developers.com/showthread.php?t=872839
This is a real, legitimate issue with Android 2.2.x Froyo. As I linked in my post, this is Issue # 11126 on Google Code...
http://code.google.com/p/android/issues/detail?id=11126
If there was an app or setting that fixed the 'suspend' issue, we wouldn't even be discussing this right now. There are fixes/workarounds for a lot of things, but right now, the 'suspend' process issue truly is a mystery. No one, not a single person has yet to post, "this is the cause of the issue," let alone a fix for it.
I wish you had a fix man, I really do. My fiancee experiences this and there's only one way she's found to sort of workaround it, sort of - she reboots her phone every morning. This seems to keep it at bay, at least more so than when she doesn't reboot each morning, once she takes it off the charger. She still gets it though and she's just used to looking for Watchdog and checking her processes now.
This thread could go on and on forever but it comes down to this:
- The MT4G does not have insane battery drain and will give you about 12 hours of life, under normal>medium usage. If your battery is draining insanely quickly AND if you're seeing the suspend process jacked up so high, then there.is.no.fix.yet.
There might be a ton of other replies after this about uninstall this, install that, change this, don't use widgets, use widgets, etc. Those attempts will be futile.
Are you having high battery drain with XXJVK firmware, or any other 2.2.1 firmware?
Does your Battery Use shows high CPU usage time on Android OS?
Then, check if you ever had Software Updates logged in! I noticed high battery usage once I logged in for OTA updates. Possibly, the device is retrying the connection to update server (which will always return timeout). You can see the Software Update service running all the time once you logged in.
If you have logged in Software Updates, go Settings->Applications->Manage Application->All->Software Update->Clear Data
Once you have logged out from Software Updates, the service disappears and personally, battery life doubled.
Thanks, i will try it!
It really could be the last chance to solve my idle-drain-prob.
i'll report back.
//edit: cleared data, service automatically stopped. i'll report back tomorrow if it solves my drain-thing.
Yup i had it running too since boot.. cleared data and will report back
Let's hope this is the answer. I've just took the drastic measure of doing a hard reset and now battery drain is pretty much zero and phone is idle when screen is off. I'll keep installing and enabling things and see what takes more battery.
Very interesting, I did check if there were any updates, and I suffered from random battery drain. At first I suspected Google Maps/Navigation, but you could be right. I started Maps, and Navigation, killed en cleared OTA, and I am monitoring the battery.
I have found that when i use the built in task manager to "clear memory" as soon as i have done that the battery drains alot faster and my android OS in battery stats goes through the roof (from 5% to something like 14%). It has been running fine since yesterday and i cleared memory only to find my battery went very quickly from 28% to 9%. I rebooted the device and all is well, i wont be using that option anymore
After installing jvk full I installed jve modem, rooted and did battery stats wipe and battery issues went away.
i lost 25% over night in airplane mode
background & sync = off.
after clearing dalvik cache & battery recalibration using battery calibrator from market i have 5-7% drain per night, and 30-40% per day... last battery time was 2d 19h 14m, with some calls, some games, some wi-fi and some hsdpa & with weather widget update every hour.
info
i9000 + JVK (repartition 512, with bootloader) + CF Root
P.S before clearing dalvik cache & battery recalibration with same use i have maximum battery life - 23h
Clear the data for "Samsung Account".

There's something very wrong with your phone, either your battery's shot or there's a rogue program draining it, you shouldn't lose more than 1-2% overnight in airplane mode.
Same problem here. I hate this device...

Sent from my GT-I9000 using XDA App
I'm seeing huge battery drain like others, sometimes more that 50% in a few hours doing absolutely nothing, wifi & 3G off and OS takes up to 60% of the battery usage. I never activated Automatice Updates since I flashed JVK. I am now on Darky's v10RC3. Only a few people are having such problems, most users say they are experiencing their best battery life ever.
I noticed that this drain always happened to me after I used Maps / Navigation. So I suspect them to create problems, maybe kicking off Software Update in a bad way. And rebooting stops the drain (it once took as long as a full flash for my phone to reboot...?).
So I have bought for $1 this nice app called Autostarts that shows which apps autostart, what triggers them to start and it is then possible to disable by app / event.
When I tap on Software Update, I can see that it kicks in on these occasions:
- After Startup
- Application installed
- Application removed
- SMS received
- Secret code entered
I disabled everything as well as for Map, so now it's no longer showing in running apps / processes.
Will follow this thread !

Spot on.
My Android OS battery usage is down to 3-5%.
Great find guys, Thanks a lot!
Also, a little suggestion here but I need someone to confirm.
Regarding Google Maps, I was having some trouble getting rid of Hotpot and Rate Places processes as they were constantly running for no reason and restart after I kill them. Another 13% drain. So yesterday I updated to Maps 5.3 and the processes are no longer there even though I've used Maps, Hotpot and Places
I upgraded with odin, repartition and bootloaders. Since now the battery life is very good, i can see the difference by eyes.

This worked for me.
Got my GS2 on Friday. Charged it when I got home to full before turning it on for the first time.
Getting a bit less than 10hrs of battery life, which isn't too bad, but use hasn't been strenuous, so not thrilled.
I looked at the battery usage and WiFi Sharing has been chewing through my battery. When I was first setting up my phone I configured it, as I do use, but haven't since turned it on, or connected to it from my laptop.
When I started writing this new thread I see there is another thread on the Optimus 2x doing the same thing. Is this a bug in Android with Dual Core CPUs?
Wifi Sharing (mobile hotspot) is a battery hog on any Android device. Thats just the reality of a good feature.
Wifi sharing is a mega power-hog, as it is essentially making a base-station from your phone. So a lot of power is used as the wifi will be in use fairly heavily.
Same on every device. Hero used to get quite warm using wifi tether.
That's surprisingly good battery life for leaving wifi sharing on.. a 10 hour wifi hotspot from a phone is about the best you can get. Not even sure if those portable wifi routers get that kind of battery life.
Yes, I know it can use a huge amount of battery. But I haven't been using it. I configured it (ie, put in my WPA key, the same one I had on my Nexus One) so I could use it, but then turned it off.
I shutdown my phone last night (took out SD card to copy a bunch of music over quickly). Since I turned the phone back on, I haven't even been into the wifi sharing menu and it's used 15% of the battery.
I will try removing the config and see if it crops up again in the list tomorrow.
Cheers, Tim.
I also have this, but do not use the feature, nor do I start it, but it still keeps appearing.
Any advice?

This is the problem. Wifi sharing is off. I configured it, but it is off. I 'forced exited' it from from the battery usage menu after I saw it, but at some point it started again.

Force exit won't do anything, it will just start up again. Make sure the checkbox is disabled. If it is disabled, try enable it and then disable it.
Can't seem to replicate it here - when I disable the checkbox it turns off.
The same thing happened to me. I configured the sharing never turned it on and it was killing my battery. I checked a million times that sharing was not active but it made no difference the service was always running. Killing the service didn't work it kept coming back. I did a full hard reset and haven't setup sharing since and it has yet to be an issue.
Kinda sucks as I need this feature. This did not happen in my atrix which is a dual core phone aswell.

Yep, I think you're right. I never enabled wifi sharing either, but I have used Kies Air a few times, and then seen Wifi Sharing appear in the Battery Usage stats.
same here set it up and not using it but it is sucking up battery .. this is a big problem. this phone isnot ready yet for my daily driver.. think i am going back to my sgs
i was getting 10% usage in about 2 hours.. i normaly get 3-5 % overnight with my sgs
anyway i have read a few threads and froze (makes them unruneable /using titanium backup .
software update
wifi sharing
and wifi sharing manager
i can always re-enable them if i want to tether
i will keep you informed on how this effects battery
i also used autostarts to disable accuweather which kept starting up.. i dont use any weather widgets other that beautiful weather which has its own
Sitting on 7% battery now. Been going all day, 10.5hrs, and NO Wifi sharing in the battery usage. Didn't turn Wifi tethering on at all today.
This morning it happened again ... But unlike yesterday, instead of killing the process I tried to enable and disable wifi hotspot and the process has finished eating cpu and battery!
I have the same problem, both Wi-fi sharing and Wi-fi sharing manager appear in my 'running services' and are consuming a lot of battery power.
I have not enabled wifi tethering, I've tried enabling and disabling, but this has not fixed the problem. I have used Kies air before, but have made sure that this is not running too.
I can force stop wi-fi sharing and wi-fi sharing manager, but they will re-appear as soon as you re-enable wi-fi.
Any idea what this is? or how to stop it?
I was having a problem with fast battery drain on my SGS2. I would get 15 hours if lucky from a full charge with light - moderate use. My most recent charge looks like it has doubled the time.
What did I change? I did a factory reset and manually installed all my apps, NOT using titanium backup. I had used titanium backup to restore apps only, that were from my previous phone (Nexus1). I have never used titanium backup for system settings, only apps, but it seems even that is unreliable. I've now stopped using titanium backup completely.

Well... Ive done several hard resets , because I though I had a network problem , and I many of those I didnt install titanium or even root the device and the battery life was the same.

If you notice a higher battery drainage than normal then you have to see what application you've installed lately. If you can't find it then the only option is to do a Hard Reset. That has worked for me, IF your battery is drained by some app which you've installed lately.
Regards.
I am sure battery drain has to do with the apps we installed and the settings we use.
We are in a fortunate situation that my wife and I have both S II, hers is 2 days older from the same shop, so I assume both devices are from the same batch. Hence no hardware difference.
I installed a lot app and played with lots of settings and if my wife like it, she "demand" to install it on hers too, so hers is a more controlled env.
For some reason my battery drains a lot quicker than hers. I still have to find out which application / settings cause this.
For an experiment, we did not use both phones for a full day (very difficult), so all the drain is due to background processes.
There are several dips in the graph, but those are explicitly usage of the phone for a while. The big last drop on her battery was because she was playing a game for more than 3 hrs.
PS.
A collegue of mine (also an SII) had his battery run out quickly, until he found out his culprit: Settings->Location and security->Use wireless network was ON.
You can see the effect of this as the "almost horizontal bar" in my wife's battery when we turned it off.
thx for info man.
What would happen if i turn that off? I want to try this to preserve my batt life. Thanks!

I installed a lot app and played with lots of settings and if my wife like it, she "demand" to install it on hers too, so hers is a more controlled env.
For some reason my battery drains a lot quicker than hers. I still have to find out which application / settings cause this.
For an experiment, we did not use both phones for a full day (very difficult), so all the drain is due to background processes.
There are several dips in the graph, but those are explicitly usage of the phone for a while. The big last drop on her battery was because she was playing a game for more than 3 hrs.
PS.
A collegue of mine (also an SII) had his battery run out quickly, until he found out his culprit: Settings->Location and security->Use wireless network was ON.
You can see the effect of this as the "almost horizontal bar" in my wife's battery when we turned it off.

The screen shot on the left is your phone correct? It looks like something is waking your phone up and leaving it in an awake state for far too long. Your graph represents over a day's time and I see those huge chunks of time where your screen is off but your phone is awake; I'd say some program is what do they call it *wakelock* every now and then.

By the looks of it, the screen was on the entire time (which seems impossible?).

If you notice a higher battery drainage than normal then you have to see what application you've installed lately. If you can't find it then the only option is to do a Hard Reset. That has worked for me, IF your battery is drained by some app which you've installed lately.

it's not just the apps that was just installed. It should include apps that are updated. I had this issue on SGS I when beautiful widget was having issues with updates causing the phone to use more battery power than usual
Morel likely to be a bad app, or a bad app setting causing the app not to close properly then drain power than the mere fact you restored it via titanium.
anyone one trying while sleeping, off your packet data ?
for me i tested,
2350 @100% to 0700 @ 99% (during packet data off)
If on, it will left 70% ++ in the next morning..
why is that so?
This is my battery drain using Litening ROM 1.5
I usually make and receive 30min phone call a day, push email on 2 accounts, wi-fi at work, data always on.

Turning off data packet doesn't allow any application going on line (unless you have your wifi on) and cannot download e-mails, synchronize anything, etc..
This saves your battery a lot.

Yes, that is also what I suspect. It is just to find out what which application / settings this cause.
I found out that I have 4 apps has an "sync" account, I delete all of them (except gmail), now I got a lot better performance (1 day: still 75%).
I'll post later my picture

Of course the updates are included. There should be an app/good optimized app which will allow us to close the apps and thus Auto Sync and Background Data to off when we are not using them, especially at bed time. The in built task manager's RAM Clearance function is crap and frankly I haven't found an app which will optimize the RAM without force losing the apps/widgets. Tried 'Gemini App' but I doubt! This 'Sync' stuff is the main responsible part of high battery drain.

Is anyone else having issues with overnight battery loss? I lost about 10% overnight in around 7 hours. I sideloaded BetterBatteryStats and I see that the WiFi is left running the entire time even if there are no running apps (and no email has been set up either). I know that on most (non-Kindle) devices there is a "wifi sleep while screen is off" setting but I don't see it on the HDX.
How is everyone else's battery life while the screen is off?

Same. There is no feature to turn off wifi automatically.

you can side load idle time connection manager which you can configure to turn off wifi after a set amount of inactive time.

Thanks! Works great. However i get 2 FC popups from gapps (which i have also sideloaded) whenever connecting to a network, suddenly they have become more annyoing. Hopefully someone will figure out how to fix those at some point
Ok on this HDX 8.9 battery life has been great. Was over 60% wifi off. Left it off or just over one day. I tried to turn it on but show'd one red bar on battery. Had to plug in and let it charge before I could use it. WOW this sucks.
No wifi nothing else left on and powered off not just simple click off.

I don't know why you guys are getting bad battery life while idle. I leave mine on for days and still have 90% three days later (after a full charge). Maybe it has to do with the fact that you have gapps on it?

Wakelock Detector reports that "Amazon Communication Services" has made a lot of partial wakelocks. I have no idea what this APK does. I have freezed it using TitaniumBackup.

It's killing my battery so I'm freezing it also. Anyone figure out what's it's for and what requires it?
If you are rooted and have installed android firewall and are using it in white list mode and did not allow all the Amazon services then some of them will repeatedly try to connect. This was causing my Kindle to be awake a lot until I renamed the apk in my rom slot. Not sure if this matches your situation but it helped mine. The service in question is inside Com.amazon.tcomm.apk.

Oh yes, that should help. Didn't think of renaming it. Will try that next if the freezing didn't work but so far it seems to be working.
