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

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.

Running Android 2.3.5
Kernel [email protected]#2
Build GINGERBREAD.XXKK3
The surfaceflinger seems to have indeed been fixed, but there is still a memory leak in the system, which I now encountered it for the 2nd time. I wanted to make screenshots, but just after I made the 2nd one, the tablet soft rebooted. It didn't freeze, it didn't show any google logo, it went directly to the boot animation and then the tablet booted. This seems to have been fixed it, unlike the previous surface flinger issue where you needed a normal reboot.
Anyway, in the 1st screenshot you can see 44h of uptime, in the 2nd one I took a pic in quick system info which displayed 198mb of free ram, just after I cleared all the processes, but then the tablet immediately soft rebooted and apparently didn't save the screenshot.
Running "ps su" in terminal emulator showed 56 rss, if I typed "su" 1st and then "ps su" there were 2 rows, one with 56 rss and the second with 116 rss, so the surface flinger has apparently been fixed.
Running factory image 4.3, rooted, deodexed, stock kernel. Has anyone experienced this issue on 4.3 so far?
LE: Oh I forgot to attach the first screenshot, sorry. Anyway it's a pic from cpu spy, which displayed 44h of uptime, so it's not that important.
I had just nearly the same phenomen. But my n10 softrebooted when I was starting to examine the process table. I just had found surfaceflinger, so I'm sure it was not that process, but sadly I hadn't found the mem-eater, when the colored X appeared.
I had done a dirty flash from aokp-pub, so I am not sure to blame android-4.3. But mem-leaks stick like sh** on a shoesole, so I'm sure, if it does not result from dirty flashing, we will hear soon from a new memory leak... (hopefully in some opensource part - cm and aokp team are faster in n10 support then google...)
I haven't had a single reboot since I flashed 4.3. My uptime is up into the 90+ hours range, and it would be higher if i hadn't had to reboot to install root, Adaway and the AOSP browser. I mainly use the tablet to browse the internet (using the AOSP browser) and reddit (via reddit news app), plus some youtube videos (using the youtube app) occasionally. I rarely play games, though I have played a little Real Racing 3 since the last bootup.
My advice is to download the stock rom from the google developers website, and completely wipe the tablet clean via the "flash-all" script. Re-install only the bare minimum apps, and see if the issues persist.
I have 4.3 from Friday. No restarts at all, but I noticed two times strange behaviour. Tablet was soo slow, every action was soo laggy. I had to restart it. Maybe its apex fault. Im not sure

Ladies and gentlemen, I present you the "suspect": Google's Chrome, the all time crap browser.
I also mostly use the AOSP browser and occasionally Opera for some downloads that I can't do with the stock browser. I installed Chrome a few days ago to see how it works in 4.3 and it does indeed work better, but the 1st memory leak I encountered happened the day I used chrome, I'm sure of it. I wasn't much impressed with it so I went back to AOSP browser and everything worked fine, then I decided to give it another try: bam, memory leak again, yesterday, the day I used chrome again.
Also, I read some comments on the forums about people having reboots on 4.3, WHILE using chrome.
In fact, in 4.2.2 while we had the surface flinger problems, I remember that chrome was the main cause.
I am back to using AOSP and Opera and everything is working superbly.

Are you rooted? If so, there is a bug in SuperSU V1.41 which causes CPU usage to sit at 100%...

Same here, might be SU fault, but I was using 1.43 when the tablet starts to lag heavily without rebooting. Couldn't find what the culprit was, CPU usage was normal, there was plenty of ram, even tried killing all background apps and services with no luck. Not even a hot boot could fix the lag.
Since then I've updated to SU1.5 so we'll see how that goes.

I got a reboot last night. Opened Google Now and it went to the bootanimation. Stock 4.3 with the Flaming Monkey Kernel, SU 1.45. It was my first reboot since January, when I went to custom ROMs. Went back to stock kernel, we'll see if that helps. Also, what AOSP Browser are you guys using? The one from the Installer from the play store closes every 5-10 minutes, and the apk ripped from CM 10.1.1.0 crashes on start-up...And I stopped using Chrome in January, and never had a reboot until Chrome was installed on 4.3. Coincidence? Probably not...
Sent from my MB855 using xda app-developers app
Never had any issues even on 4.2.2 with any sort of memory leak. Was able to go at least 5 days without any reboots and that's with using the chrome browser. I haven't used 4.3 long enough to post my findings with it but so far after 3 days it seems to be about the same. The only thing I can think of is that I bought my Nexus 10 in May so I don't know if a newer hardware version would make any difference.
Also, those of you with random reboots have you tried updating your boot loader yet? Not sure if or how it would make any difference but it's worth a shot.

Hello all,
I own an international N9005.
Up until recently, I used the stock Samsung ROM with good battery life.
A couple of weeks ago, with no apparent reason, I started getting horrid battery life - in access of 10% drop -per hour- in idle (as opposed to 1-3%).
I removed more-or-less everything, disabled more-or-less everything but nothing seems to work.
Got root (there goes the warranty) tried looking for Wake-locks and nothing. The Note3 is 97% (!!!) awake even with everything disabled, and in the wake looks screen both user and kernel I only see 1-2 minutes (!).
Tried resetting the ROM, tried installing other custom ROMs (X-Note, Omega, etc). Nothing seems to work.
Currently I'm running Omera v20, with *zero* applications installed (including all the Google and Samsung applications beyond Google Playstore) and all external services (location, WIFI, et-al) disabled, my note 3 is still 95-99% awake, and the list of wake lockers is, errr, empty.
FWIW I'm ~100m from the nearest cell tower.
EDIT: According to battery meter, Android OS is keeping the phone up.
Any ideas?

Indexing your external SD maybe?
You could try the link in my sig and try again for your custom ROM.
First, thanks all for taking the time to answer.
I'm thinking about getting a new battery, but my gut feeling is that its not the source of amazing battery drain - ~20%/h while completely [!] idle (auto-sync/location/etc completely off).
I've attaching /d/wakeup_source in excel format sorted by count and total time - in-case someone has any idea what's completely broken.
As far as I can see, qpnp-vadc-ebd30a00, sec-battery-monitor, mmc0:0001:2 are the main culprits.
nicholaschum,
Before I attempt a complete wipe (as opposed to the normal wipe data / cache), how can I detect if someone is indexing my sdcard? (which may account for the mmc0:0001:2 in the wake lock dump).
- Gilboa
I know this is a long shot but try turning off developer options if you have it turned on(especially force gpu rendering). Somehow I found out that when I turned it on and the screen is idle. I get a battery drain. Not as big as yours. But not really sure because if I use the phone, the battery is actually pretty great(an hour of screen time is about 10% even more with internet apps like facebook youtube chrome etc.).
Clear cache. I know this is too common but it actually works for a lot of people.
Lastly, try airplane mode overnight and see if it doesn't drain. It might be your network that is causing the drain.

Hi, basically just check your phone using BBS (BetterBatteryStats), and see which individual process is eating up your battery.

Already installed - together with WakeLockDetector.
Short update, out of pure desperation I completely wiped the phone (including sdcard), tried installing stock ROM and, err, Odin failed. Managed to get CWM running again and installed the latest CM nightly.
...
As weird as it sounds, going from NF4 based ROMs (including stock) to CM nightly dropped to idle battery usage to ~2-6%/h, a huge drop from ~20%/h.
I'll update and mark resolved if this situation holds (crosses fingers).

I heard there were problems with NF4 battery. But I haven't been on TW since ND4. No matter what on Note 3 TW the battery sucks. AOSP is great. But actually S5 port has the best battery.
Solved, at least for now.

I use Nova (and not TW)
Either way, latest nightly seems to solve the battery drain problem completely - using the same Nova and system configuration (widgets, active syncs, etc). Currently I'm at ~1.5-0.8%/h when idle with no issues going into deep sleep.
Seems that my specific model really dislikes NF4.
Thanks again for trying to help.
This thread has been quite helpful as I was suffering with a Battery Drain after the NF4 Upgrade.
Planning to go back to ND5, which was the last stable version.

I was thinking about doing the same, but in the CM 11 runs circles around both NF4 (duh!) and my previous ROM (not sure which revision it was) - plus I can actually get 2 days of standby time, even with the old batteries, so I'll stick with CM 11 for now.

Hi guys,
I ordered a GNote 3 and I'm really excited. But I read a lot of stories about the lollipop really buggy, memory leak, and battery drain. But I don't see many comments about these in the ROM thread, and someone mentioned that they like Stock lollipop better than CM12. Does this mean stock lollipop for Exynos is working fine? I don't have the device yet, so I have no way to try out yet myself, but I plan to flash my desired ROM right away when I get the phone. It could be one of the TW lolliop ROMs or CM12.
Just a note that I would love to run lollipop, and not kitkat. So could you please advise around that? Are there tweak that people use to fix the issues?
Thanks!
Hello!
Right now I have over a month testing the stock LP ROM on an exinos device, it has been quite a good experience, the ROM is very responsive, and although it has a huge memory leak (I have found my device running on RAM as high as 85% with no running apps, just running the processes needed for the OS to run) nevertheless I can harddly notice any lag n the system, I use Clan Master to monitor RAM usage, when I find my device I use the clean now feature, and the RAM usage goes back to around 60-65%.
On the battery subject I run my Note 3 paired via bluetooth with a Gear S, and I am getting between 20 to 24 hrs. Of continuos use, so taking into account I am always running with bluetooth on, I think I am getting a pretty decent usage time, I would like to let you know that I mustly connect to the internet via WIFI, only use Celllular Data when driving or in places where there is no WIFI available.
After installing LP ROM I went straight to rooting my device and installing Titanium Backup in order to be able to debloat, I have managed to uninstall APK that I found useless for me, and got rid of them, also I use Greenify and I have greenifyed every app not essential, I also use Startup Manager ( Free) to get control over what apks startsup.
Finally, I use tasker to get control over how my device handles the changes between Cell Data and WIFI.
I hope you find this information useful, and please excuse my english!
Hi, so I've had my G2 D800 model for a while (about a year or two), and for the most part, it's been an excellent phone despite being 3 years old now. Never had any slowdown problems, and it's always performed well in games and in general.
But just recently, about a week ago, it just started lagging out and being very, very slow.
For example, if I'm watching a YT video through the app, if I rotate the screen, it takes maybe 5-8 seconds to actually rotate. Also, in a lot of circumstances where the keyboard has to pop up, it just freezes the app until the keyboard pops up maybe 10 seconds later.
It's also just laggier in general in most apps, scrolling through FB or Twitter freezes nearly every second when I'm scrolling. It's generally unresponsive and sometimes just freezes outright. It also acts this way on the homescreen, and in most everything else.
The most annoying part, however, is that sometimes the devices just doesn't turn on for sometimes up to 15 seconds after pushing the power button (and it usually just refuses to turn on when using my knock code).
The odd part, however, is that once it's actually in something like a game, it performs perfectly fine.
I've played a number of Cardboard games, as well as games like Nova 3, and it performs perfectly.
I've also ran multiple benchmarks (Geekbench, 3DMark, etc), and it scores around where it should.
Info about the device:
LG G2 D800
Stock Lollipop 5.0.2
Software Ver. D80030f
Kernel Ver. 3.4.0
Rooted
TWRP Recovery installed
XPosed Lollipop installed
G3 Tweaks installed, a number of tweaks applied
Everything else is stock (homescreen, etc)
What I've tried/checked:
Checked memory usage during "lag sessions", rarely dips below 300mb free
Changing minfree values through Rom Toolbox (tried every preset, as well as setting everything to the max to free as much as possible)
Rebooting (affects nothing)
Checked CPU speed with Rom Toolbox (is at max, and does achieve the max speed of 2265 MHz. Setting it to performance mode/setting the min speed to be 2265 MHz has no effect, but reduces battery time)
Changed default cache sizr (tried every preset from 128kb to 4096kb. With multiple benchmarks, the optimal value for r/w bounced between 512kb and 4096kb, currently on 4096)
Things I have not tried (that I am aware would possibly have an affect):
Changing anything in the kernel tweaks/build.prop
Completely wiping, reformatting, and reinstalling (I really would rather avoid this if possible, as it would take a while to get everything back to what it is now, and it was a pain to upgrade to Lollipop in the first place)
I am unaware of anything else I could try to fix it, which is why I'm here
So, does anyone know of any other solutions or things to try? This has made my phone very unreliable, even for phone calls and messages, which is a problem.
Thank you for your time and help!

Hi, so I've had my G2 D800 model for a while (about a year or two), and for the most part, it's been an excellent phone despite being 3 years old now. Never had any slowdown problems, and it's always performed well in games and in general.

Hi,
First thing i need you to try out is this custom kernel : http://forum.xda-developers.com/lg-g2/development/lp-5-0-2-kernel-3-4-107-dorimanx-1-0-lg-t3102512
Then install greenify, and hibernate all the unnecessary apps.
This should solve the issue.

Thanks for the quick reply!
I'll try out greenify, though there aren't many unnecessary apps running (i uninstalled all the bloatware first thing, when I rooted).
And about the custom kernel, it's something I've never tried, so I have a couple questions.
Will it wipe my device, or break TWRP, root, or Xposed? (Sorry, didn't see the answer on that forum)
Will a TWRP backup I make be able to fully restore my device to it's current condition?
Is everything that is supported on my device be supported with that kernel? (Apps, etc. Don't know a whole lot about how kernels work, so I don't know)
Thank you!

Hi,
Even you uninstalled bloatware, the apps you use daily could be running in background and taking all those rams. So whenever you play a game or dont use a certain app, just go to greenify and hibernate. Since you have xposed installed, you can do more than that such as u can stop sync , etc.
About the kernel, it has a ram management settings and cron task.
Ram management dont need to be altered. It has some preset profile so if you seek performance, just choose performance or if u need battery , select battery profile etc.
Cron task is useful because it will do alot of things automatically. For example, it will release ram at certain amount of time from the apps , it will restart google play service since that could be an issue , etc.
All you need to do is take a nandroid backup just to be safe. Then download Dorimanx Ota from playstore and it will detect ur device and show u which version of kernel is available. Then download that, go to recovery, flash it, and you will see three app installed : Synapse -- will give you all the details of ur setup including cpu speed, temp etc for monitoring purposes
Dorimanx settings - this is the main settings of the kernel. You will see a P icon on top, tap it and choose your desired profile.
Color management : It is as the title says, just leave it be.
Then use your device, check your ram and report back. Hopefully it will resolve your issue.
Wow. Dorimanx did a lot more than I was expecting.
Downloaded the app, downloaded the kernel, flashed it no problem, went through and checked out synapse.
Went into the Dorimanx settings, and set it to the "Performance" profile.
Immediate improvement.
The whole phone seems a lot more snappy, and I switched back and forth between a 1080p60 YT video, facebook, and twitter with absolutely no problem.
Free memory when idle (no apps open) stays around 1gb; it used to be about 500mb before.
Tested a few games for the heck of it, and it actually seems to have improved game performance somehow. (It seems to have overclocked my CPU to 2.5ghz, though, so that makes sense.)
Temps stayed at around 58-60c while running a few Cardboard apps, so it seems fine.
Thanks for the help iubjaved! This has fixed my issue and then some! Ah, the wonders of the Android dev community.
