I dont have androidOS bug..tapi my android system is 42%....can I assume androidOS same with android system??
[Nexus S General] jeremy112683:
Usually my main issue is mediaserver. But I have used any music apps today
[Nexus S General] bedalus:
Thanks to all the people who replied.

For the people with the OS drain, these apps are in common:

Youtube 3/4

Whatsapp 3/4

Titanium Backup 3/4

Maps 3/4

Google Search 3/4

For the people with no problem:

YouTube 1/5

WhatsApp 2/5

Titanium Backup 5/5

Maps 1/5

So, although it's a small sample, the most likely candidate for causing this bug is Google Search. My guess is that the search app incorporates the new Google Now thing, and is a hungry app, but is listed as an OS stat, because it is a Google product.
[Nexus S General] apatal:
I have Google Now disabled and I don't suffer from this high Android OS issue, so this may or may not support these findings. However, battery life in JB for me is really quite short. Not sure if it's the modifications by project butter or something else but I learned to live with it, since the update is awesome. Can't get something for nothing, I guess. Life is all about tradeoffs. :)
[Nexus S General] bedalus:
I suppose people with the app can disable it like apatal, see if this is sufficient to clear the bug
[Nexus S General] Articudos:
Well, I never enabled google now..

+Never used google search via app;)

BTW, it can't be catched using betterbatterystats?
[Nexus S General] 063_XOBX:
I'm not sure that any of those apps can be blamed. Sure, 3/4 of the reported users have them installed but they are all apps that most power users would have (except whats app never heard of that) I have all of those apps and have never experienced SEVERE battery drain.
[Nexus S General] unlinker:
I usually have no androidos battery drain, but yesterday my phone has gone crazy with 60% of androidos usage. I usually run air kernel and this happened to me just once, do you want my infos too?

Sent from my Nexus S
[Nexus S General] bedalus:
It's not a severe battery drain problem, just a little higher. The main issue was determining the source of the high Android OS drain to make sure it wasn't a kernel issue.

Thanks again to everyone who helped narrow this down!
[Nexus S General] Aceangel21:
As one of the users who put their app info in, android os problem is confirmed gone after disabling location and search and flashing v4.5. Thanks for all your great work bedalus!
[Nexus S General] bedalus:
Thanks for your help!
[Nexus S General] EleventhHour2139:
How does this effect Google Now? I'm all for saving battery life, but I'd hate to do it at the expense of handcuffing Google Now.
[Nexus S General] :
I actually have no idea! I don't use it. Try it out and feedback?
[Nexus S General] evcz:
Yeah, let us know what happens to Google Now disabling that :)
[Nexus S General] jeremy112683:
Looks like it just makes Google now say your location service is off. So I guess turn it on when you need it. That setting is just like turning GPS on and off except its using your network signal or WiFi.
[Nexus S General] 309041291a:
Yo Beddy (Terrible attempt at a nickname... ignore that...), have you put in the 'powersave' governor in your kernel? It's great for a screen off profile in SetCPU, smartass doesn't do the job as well.

I have titanium, YouTube, Maps, and search installed. Google now off and location off. I have the android system bug, I believe Maps and YouTube are the cause.

Nexus S. (GSM i9020a)

Paranoid Android (2.0 - 4.1.1)

Air Kernel (JBN Stable 1 - Voodoo)

OndemandX (Screen On) (800/100)

Powersave (Screen Off (400/200)

Deep Idle (N/A - Deadline)

BLX (98 - Inverted Apps)

Black Exodus (Stock Voltage)
[Nexus S General] qaz2453:
I have got Google now + gps on .. I'm at a steady 3% Android os usage
[Nexus S General] ADJack:
I've deleted Google Now and have always disabled any sort of location tracking and gps permanently on my phone for some time now. When I saw the [SOLVED] tag, I was not expecting that the cause would be attributed to those things. Before flashing marmite 4.5, I was on Flo's JL OTA with 4.4 - all location tracking and gps off (settings menu), google now deleted, gmail deleted, maps deleted, email deleted, exchange services deleted, calendar deleted, search bar deleted - all through titanium. Primary uses are: kik messenger, talk/text, poweramp, youtube and occasionally dolphin browser if I'm too lazy to get on a laptop/desktop. Before updating the kernel, OS was at 19%. I've let it sit for a while and did some messaging - OS is at 7% and System at 8%.

EDIT: OS back up to 17%.
[Nexus S General] :
Android system and OS are two different things. No one else is complaining about Android system, so you may have some other issue. My guess is an app.

Regarding powersave, I'll quote Ezekeel, who discussed with morfic that limiting the maximum frequency can save power, but only if the system doesn't make proper use of the chip's idle states. Obviously neither form of deep idle is working properly at the moment, so my suggestion is to use Ondemand which will keep the frequency low during screen off with processor activity, versus smartassV2, which takes longer to scale down the frequency.
[Nexus S General] Erythnul:
I came here to put in some input as well. I have all location tracking and Google Now enabled, but until yesterday, have been experiencing major battery drains from Android OS. I tried many things, including disabling GPDS/Location tracking/Maps/Now, but found the issue was something else entirely. Thus, I don't think the [SOLVED] tag is warranted by blaming the drain on GPS/Google Now/Maps. Android OS drain is a complicated issue with many possible causes. For example, this was my experience (solved it yesterday to my great relief):

Android OS was consistently keeping my phone awake, reboots were no help, checked out everything I could think of (including shutting off Google Now/Maps) to no avail. So I started digging into my BetterBatteryStats. Eventually, I managed to interpret BBS well enough to trace it to suspend_backoff (which keeps the device awake if it gets many wakeups within a few ms) and mmc_detect1. Connected my NS to my computer, mounted the SD card and checked it for errors, Windows reported and fixed an error in the file system and then I re-mounted/disconnected. This fixed all of my issues and my device now sleeps properly, battery life is completely back to normal. Apparently, in my case, Android OS detected the error on the SD card and kept trying to read it, causing constant wakeups when it should be sleeping.

I think anyone with the Android OS problem should install BBS and we should do some comparing from there. Each problem could be individual (I think I may have caused some corruption on my SD card myself by not properly mounting to the computer, though that only happened once or twice, so I can't be sure).

However, there could be a consistent problem causing this behaviour in multiple devices and multiple configurations, and the only way to get to the bottom of it is to check what causes the drain, and I highly doubt that any user-installed (non-root) apps have the potential to screw with Android OS on such a massive scale.

I'm expressing myself horribly here, I'm sorry. However, I hope I got my point across.

To summarise: Google Now/Maps is not to blame in my opinion, Android OS drain is a symptom of some other underlying issue or possibly multiple issues across multiple devices/configurations. We should work to get to the bottom of this and not shift the blame onto a few apps/GPS without good evidence.
[Nexus S General] :
Thanks, I'll link this post in the OP.

I had some problems when I switched to JB, that disappeared after formatting the SDCard.
[Nexus S General] polobunny:
This thread is lol worthy. Location has always been a known battery drain and used to be more centered around Maps. I can't imagine people who got big Android OS drain are all too dumb to do a modicum of research and actually disable that before crying for help. Please tell me it's a joke so I can have faith in humanity still.... @_@
[Nexus S General] :
Sorry, we're all doomed!

Edit: just to clarify, a lot of people posted on my thread that they were having high Android OS drain, but not complaining elsewhere, it made me wonder if it was a kernel issue.

Eventually I realised it couldn't be, and narrowed it down to this search thing. However, I personally had an issue with high drain that disappeared after formatting the sdcard.

So the old axiom of battery saving still applies... The less you have switched on, the longer your power lasts. But occasionally, you might want to do a complete spring clean of your entire flash memory. At the very least, it's a good excuse to backup your photos!
[Nexus S General] polobunny:
If I can ever get some time for xda stuff other than at work I'll have to flash your latest kernel with so said android OS battery drain. Because so far mine is at 4% with knzo cm+ kernel. If for some reason it jumped much higher than I guess it would be worth investigating. Never really got a huge android os usage in pretty much as far as I can remember, after disabling all the features I don't want/need/use. Still curious about this ordeal.
[Nexus S General] apatal:
I never really had any problems when I switched to JB, except for the high battery drain, which I attributed to project butter since I didn't get the high Android OS issue. However, after I accidentally formatted my NS USB storage (during one mindless wiping booboo), I did notice improved response and more buttery animations. Battery life stayed the same however, so I just accepted it as a given. I did decided to go back to using ondemand, as opposed to interactive governor, since I noticed the former makes more efficient use of lower CPU frequencies, which I hope leads to slightly better battery life.
[Nexus S General] ratlik:
helped for me

Thanks that helped.
[Nexus S General] EleventhHour2139:
^This. And unfortunately, I've been trying this for a while, and no noticeable battery savings.

I'm actually wondering if my battery isn't starting to kick the bucket, these days I'm *barely* getting 2 hours of screen on time. Coming from 3-3.5 on ICS, and over 5 on GB, this is effing depressing :(.
[Nexus S General] :
You should be able to get more than that. You might need to download some battery monitoring apps to determine which apps are responsible. You might want to try a different ROM. Someone in my kernel thread managed to get 5 hours screen on time. Presumably he doesn't have a brand new battery either.
[Nexus S General] VerneVerne:
Could be a battery issue but my nexus is only a few months old and since JB came out i can't go a few hours without having to charge. All location apps turned and even with the screen off i get horrible battery drain. And this is with a fairly new phone and battery
[Nexus S General] Erythnul:
Then give us some info please, maybe we can fix it :) First off, install BetterBatteryStats from the Play Store or here on XDA. Run it and activate the root functions in the advanced settings. Once you're all set, charge your phone and try not to use it too much, if at all. Let it sit and drain for a while. A phone that goes to sleep well is generally much better, battery-wise, than one that doesn't. Wait until your phone is drained to like 30-50%, then make a couple of screenshots of the following:

Your regular battery stats screen

The deeper regular battery stats (tap the graph)

Screen on time

BetterBatteryStats Partial Wakelocks

BetterBatteryStats Kernel Wakelocks

BetterBatteryStats Alarms

BetterBatteryStats Process

If it's not set correctly, be sure to set BBS to "since unplugged" as reference.

This way, there is practically no way that information will be missing. We should be able to find out what's going on and how to fix it (if that is possible) :)
[Nexus S General] EleventhHour2139:
I have (well, had) bbs installed, along with a few other root-enabled monitoring apps, however my power button is broken and retarded me flashed a non-rooted stock rom. So until I can pony up the $ to get it fixed, no root for me :(. I would just use adb but I've had zero luck getting it to work on windows 8. Figures right?

I know troubleshooting such things without the right tools is borderline pointless, but for reference I'm running stock jb rom, stock kernel. Unfortunately, since this is my daily driver I can't really sacrifice reliability, although I'm hardly suffering since ics/jb.

My apologues for the long quotes.
[Nexus S General] madd0g:
Just for future notice, my NS was behaving weird suddenly and had high Android OS "usage". When I checked the BettterBatteryStats app, it had a high wlan-rx kernel wakelock. I've browsed around the internet and one of the suggestions was that something is keeping the Wifi on the phone active, so it doesn't sleep.

In my case, the culprit was the LanSync option in the Dropbox desktop application, so when I disabled that, the wakelocks and Android OS "usage" stopped. I did have an experimental Dropbox app installed on the desktop, so this might be at fault also. But so far I know, mobile android Dropbox app doesn't support Lansync anyway, so for my home network it's useless anyway.
[Nexus S General] :
I suppose android os is a wide umbrella, and potentially a lot of things fall under it, so one statistic isn't particularly useful for all the possibilities. I hear better battery stats is a useful app for seeing what's really going on.
[Nexus S General] madd0g:
Indeed, I hope Google can provide more specific stats in the future editions, maybe enabled under Developer options or something.
[Nexus S General] ryuken80:
how about mine,i have 50% android OS,i runing stock root,this happen twice on my phone

[Nexus S General] snandlal:
I have added this fix: https://github.com/snandlal/frameworks_base/commits/wip to my ROM and now my Android System is averaging 12% and my AndroidOS is at 4-6%.

Applying that fix to my source and building my ROM did the trick for me. I was at 20 + % before this fix.
[Nexus S General] snandlal:
I will probably be releasing my ROM soon. So everyone that has this problem can try the fix out themselves.
[Nexus S General] :
My system is 8% my os is 3% my screen on time is 1hr and my uptime is 13hrs, without any special tweaks.
[Nexus S General] snandlal:
Thats excellent. Wish mine was that low.
[Nexus S General] :
Have you tried using better battery stats? It might tell you if there is a specific problem with one of your apps
[Nexus S General] snandlal:
Will give it a whirl. Thanks buddy.
[Optimus One, P500, V General] vlt96:
HP has made webOS open-source! It has a linux kernel too (as I read) so maybe someone can try it too? Since B2G was successfully build by adfad (not yet flashed on our phone) we can get our hopes up a little bit :D

http://www.openwebosproject.org/

I wish everyone GOOD LUCK!
[Optimus One, P500, V General] aspee:
Sorry,I have 64bit machine and its not supported although we should wait more and found out what other phone developers think.
[Optimus One, P500, V General] adfad666:
WebOS is quite unlikely, more unlikely than B2G. It's written from scratch whereas B2G is based on the android subsystem, which is why we can get it to work on our phones.

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Deleted member 4736004:
Why dual boot ? Dual boot if not handled properly can mess up your device ... So my advice is don't..
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] ScatteredHell:
I don't think so bro, even we can't use Xrecovery(correct me if i'm wrong)

Possible to dual boot with (Xrecovery and CWM required)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] rahimali:

could somebody shed some light on this please. thank you!
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] yannick61:
I would love to dual boot my own customized rom and stock ics rom
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] tux-root:
It might be difficult doing multiboot using difficult kernels. In this news http://www.xda-developers.com/android/dual-boot-your-favorite-roms-on-your-xperia-play/ the way is using one kernel for two roms. In this thread http://www.xda-developers.com/android/dual-boot-roms-on-the-lg-gt540/ solution for LG smartphone every rom is suited to fit to dual-boot solution individually, not every rom functions here.

At last in this blog (german source, http://techgeek-live.de/2012/04/05/dualboot-android-clockworkmod-betriebsystemen-sw/ ) you are supposed always to flash back backups of your different roms, but in my opinion it needs way to much time. It would be cool to have a one-click-option which rom to boot. And what about message and app synchronisation? Maybe there are ways to automate such processes, but it might need a huge amount of effort.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] panamamike:
I'm a fan of the dual boot. I've seen this on the nook color. Pretty neat being able to simply remove the sdcard and go back to practically stock or whatever you want to have as the base.

Is the nookie implementation similar to the dual boot options you've listed? Wondering why it's not possible or not a good idea for xperia.

Regards,

Mike
[Samsung Galaxy Nexus] famester:
So the cable that came with my gnex will no longer charge it. It will charge my old rezound however. So now I have to use my rezound cable for my gnex. Its quite a bit shorter so its a pain in the neck. Just wondering if anyone else has had this issue and if there's a fix or anything I can look into I'd like to use my longer cord cause the battery is not very good on this thing either so being tethered to a wall with only that small cord is quite a pain.
[Samsung Galaxy Nexus] Teoctist:
How old is the cable?

I never had this problem, but why not buying a new cable? or just a extension cable to make your old one longer? As far as i know they are pretty cheap.
[Samsung Galaxy Nexus] famester:
Its a month or so old. Before I forked the few dollars over I figured I'd ask around if anyone had this issue before and knew of some odd fix. Just seems weird it works for my other phones just not the one it was designed for.

I baught a class 4 sandisk 32GB memory card .

it is written 720p HD video on back of the cover.

what does that mean ? i cannot record FULL HD video with this memory card ?

does that i cannot transfer full hd video to it ?

Anyone can clarify this please ?
[Galaxy S III Q&A, Help & Troubleshooting] sjgore:
You need a minimum of Class 6 for recording 1080p video.

That said, branded SanDisk SD cards are usually a bit faster than their rated speeds, so you might be alright.

Its really hard to understand but I don't think you unlocked your boot loader and flashed a recovery.

What method did you use to root?
[HTC Amaze 4G] Gasuky:
i`m root with unlockroot.
[HTC Amaze 4G] Dark Nightmare:
How sure are you that you're rooted? Anyways, if you just used an app to root, it won't be possible to flash a custom recovery until you unlock your bootloader.
[HTC Amaze 4G] Gasuky:
hello, I have not posted before, it broke my wifi.

Turns out my ruby, is a Chinese clone, if you have not unlocked the bootloader, but try to flash the recovery.img with flashtools and I did, but it was starting to 3e, so try flashing boot.img, a boot.img flashtools accept, and did, but when you restart the phone, it stays in green android screen with black background.

Any idea?
[HTC Amaze 4G] Dark Nightmare:
You honestly lost me there, if your device is a Chinese clone, why would you attempt to flash files from this device to begin with? You'll need the stock files for that device to recover it.
[HTC Amaze 4G] Gasuky:
of course, but i buy an Htc Amaze 4g and not a chinese phone. i dont know that thing, and now flash recovery.img and boot img compatibles with htc ruby, with flashtools and my phone fake is brick. Only on to android green and hold in that screen.
