    Tesekkur ederim arkadas. This is the most comprehensive answer I have had up to date. Knox really is working constantly and I have noticed that when I use the phone battery consumption is normal, but when I let it sleep it drains like mad. Just as the video showed, Knox is working constantly using a huge chunk of my cpu. I'm thinking of rooting and trying to remove Knox or down grade to 4.1.2.
    Comprehensive but I'm not entirely sure Knox is to blame, least not entirely. Its easy to blame bloat ware though. However I was seeing terrible drain after the update and for weeks it's had me stumped. Until Google released an update to Google Play Services which in the update notes stated it addressed battery drain issues. Once I downloaded the APK (I could have waited for the update to be pushed but wanted a fix now) and installed it, the effects were instantly noticeable. Google Play Services completely dropped off my battery usage screen and my battery was back to performing as good as if not better then what it was on 4.1.2.

    Can you please tell me where you got the APK fromt md? Google services have had an update recently but I'm not sure if that was it. It made no difference on the drain.

    I did the following, and it helps a lot, like before upgrade to 4.3:

    1) install Greenify - the new version support non-rooted device; and hibernate all applications except Whatsapp and other Apps needs to run all the time
    2) In Manage Apps, browse through All Apps, and find all those Samsung services: "....syncAdapter", "backup provider", "cloud...","push service", "print service", "link"..., turn them off and Forced to stop


    Actually, Note 2 belongs to my wife, which is not rooted. My own S3 is rooted, and runs AOKP android 4.3, which does not have battery drainage ..... so 4.3 & google service is not to be blamed. If I have time, I would root the Note2 as well to get rid of all those useless Samsung service.
    ( I disabled location reporting, but allows Android device manager to remotely located it)

    I have installed Greenify but it only shows normal downloaded apps. It does not show Knox, which is I believe the main culprit of the wakelocks. I will probably hibernate most apps but I doubt it will solve anything. Before 4.3 and Knox my battery run for days without Greenify.

    How do I Remove/Uninstall Knox Personal on my Samsung Galaxy Note 3? : T-Mobile Cell Phones | Samsung
    Hi Guys, I am from India. This post is very very relevant to what is happening to my Note II. I installed the Usage App from the video and found KNOX doing the same as explained. I was also on 4.1.2 and upgraded to 4.3 and did the very mistake of accepting the small security upgrade by Samsung later. The link above is not really helpful for uninstalling KNOX. When I clicked the KNOX shortcut in my cellphone, the initial screen is asking me to Install it now. What a joke!! So there are no such options as explained in the link. Probably it is something specific to T-Mobile and completely irrelevant to a person like me in India where the service provider doesn't even exist as a carrier. If anyone finds a real solution, please post. Thanks to you all for this post!

    I pressume that for this to work KNOX has to be installed already. I have not installed it. The one always running in the background is a KNOX component (there are three that came with the 4.3 update). If after you've tried this, KNOX and all of its components are forever gone please let me know so that I can install it and then uninstall and get rid of everything together.

    I don't understand the hubbub over Knox. I have two Note 2's here with 4.3 and neither one drains the battery any faster than the past 15 months on the previous 2 OS releases.

    I tried, and found the same message .... prompt to INSTALL Knox. So, I didn't install. Knox is in fact not running in my case. In Manage Apps, I have Forced Stop all Knox related components/services.

    Nor me. I think it's a red herring to be honest. I don't see anything related to KNOX eating my battery at all. My battery drain rate is as good as if not better then it was on 4.1.2.

    A few of us here don't seem to be facing this issue but I have confirmed that KNOX is eating a lot of my cell RAM + CPU. It has to go from my cell!!

    serkansancak, please please please spend some more time to write it again for us (prob in Notepad first and then copy-paste here).

    Thanks much in advance for helping rest of us here...

    Your experience and that of the many reporting a problem suggests that it doesn't have a simple or obvious cause. My wife and I each use the Note 2 and have seen a substantial loss of battery life since upgrading. These are our only phone and Internet access and are used a great deal in areas with borderline cell reception. None of this changed after the problem began but this type of usage may have exacerbated it. Your usage and service environment may minimize the issue. In any case, a substantial number of Note 2 users are reporting problems and no user initiated solution appears to help most of us. Samsung must make this a priority.

    Not at all Christos! You welcome.

    Yesterday I wrote a very detailed answer but it's lost anyhow. I'll try to summarize once more. I'm also adding some replies to some posts.

    This may help but needs to be tested. Past 11PM my time, so need to go to bed. Let me know if you guys give it a try.
    Not gonna work. This is only for installed Knox interface which allows you to use a "secure" 2nd desktop like you are using a second OS. But in some sources they announced that it is not "that" secured and should be fixed. Even if you do not install it there are 7 or 8 files related with it and they are system apps that is running!

    Comprehensive but I'm not entirely sure Knox is to blame, least not entirely.
    Exactly! It consumes a great amount of battery but other programs too. The case is, it keeps some programs wake that should be in deep sleep mode when device is not in use, at least they were before Knox. So it consumes battery with other apps but it is the core of the problem.


    I don't understand the hubbub over Knox. I have two Note 2's here with 4.3 and neither one drains the battery any faster than the past 15 months on the previous 2 OS releases.
    Actually that was the aim, to use battery source more efficiently. But it failed in most of the cases. I don't know how and why it failed in some cases and not in others, but the problem is that it seems nobody knows the reason! Another side is you don't have the rights to uninstall it, and it is a new user that is using YOUR phone! Well I don't wanna share my phone with anyone! You can see in some cases (when it asks as which user you like to perform a task) that it is a new user that has full root access to everything. There should be user and virus program with restricted access at this step. But Knox is more powerful on your phone than you are. This is what is wrong about it.

    I tired many ways to get rid of it but all the methods described on the net has been failed. Some methods might work if you do not make the security update after you upgraded to 4.3. (I installed that security update ). While finding the method I will describe below, I tried others too, and one of them void my warranty and the methods to set the counter back to zero is not working on 4.3. If you know a method I'd like to learn and will appreciate! Therefore I will summarize the method skipping the parts that I did but not necessary for the success.

    Before we begin there is a point that I should say. I installed SuperSU few times on my previous attempts but it has been removed by knoxed system. When I started the method described below, I don't have this app anywhere on my phone. But after I manage too root my device it pops up! Don't know if Kingo Root installed it automatically or it appeared back because I installed it earlier.

    Now try the method on your own risk!

    Step by step:
    0) Before you begin make sure that Kies is connecting with your phone with no problem and all necessary drivers are installed on your PC for the communication. And also make sure that under developer options USB Debugging is checked! (I'll write how to do it after, if you don't know how, because with 4.3 developer options is gone!
    1) Install "Kingo Android Root" ( Application Download Link Removed by Moderator ) to you PC. It will not root your phone without following the other steps.
    2) Install "System App Remover" (the one by Jumobile) from play store. The app will be installed as a different name, as "Uninstall". I tried "All-in-One Toolbox" too but it coudn't find all the files listed below (namely KLMS Agent). So I had to install this one and try again.
    2.1) Install "Root Checker Basic" from play store.
    3) Go to Menu>Settings>More>App Manager>All and force stop the apps:

    com.sec.enterprise.knox.attestation
    com.sec.knox.eventsmanager
    Security principle (or element) update -- (Probably you have this if you installed the security update after 4.3 upgrade. I'm not sure about the file name because I translate the name from Turkish)
    KNOX
    KNOX -- (Yes we have to of them! One is to install Knox interface other one is the one that is already running without installing the other one.)
    Knox Notification Manager
    KNOX Store
    KLMS Agent

    In total we have 8 files (or actually apps) to close. You may have 7 of them if you don't have Security Principle Update.
    Some of these will not gonna allow you to force stop, never mind, just close the ones that you can.
    4) (Now you have to be quick because somehow these apps restart themselves.) Connect your phone to your PC and run Kingo and click root then follow the instructions on your pc screen. Your note 2 will restart and will be rooted.
    5) Disconnect your phone.
    6) Run "Root Checker Basic" and click "verify root access" and see if you are rooted now. (You should be rooted.)
    7) Install "SuperSU" from play store.
    8) Run "uninstall" (which we obtain by installing "System App Remover" (the one by Jumobile)). SuperSU will ask for root permission for uninstall, approve it. Uninstall will provide you a list, choose all the apps listed above and uninstall them. KLMS Agent will not be in the list and you should use the search option of the app. If for any reason you don't see any other app in the list search and uninstall! YOU SHOULD DELETE ALL 8 FILES!
    9) Restart your phone.

    Congrats!

    Hope it worked for you too.

    Actually I installed Battery Doctor before I rooted and remove Knox and it really helped a LOT! But still not as good as I was in 4.1.2. Now I'm back to normal again! Besides while having Knox I had some other strange things like the device restarting itself even in a middle of a call. I don't know what caused those anomalies, may be Knox may be I tired to many things on my poor device. However, now it seems all is gone. Besides Knox is not watching me anymore, the best part!

    I'll try to uninstall battery doctor in few days to check the difference. If you don't want to root your device you can use it for a better result but NOT completely back to normal.

    To access developers options if you cannot access after 4.3 upgrade:

    1) Go to Menu>Settings>More>About
    2) Now scroll to "Build number" and tap it 7 times.
    3) After clicking the Build Number 7 times, you will get a message saying "Developer mode has been enabled.
    4) Now the "developers options" will be under Menu>Settings>More>

    Hope I could managed to explain clearly.

    Hurray!!! I have done exactly as you have described and got rid of all 8 af those annoying apps. Security Policy tried to block me from rooting and from uninstalling but my root apps prevailed and did exactly as I wanted them to do. I will see how the battery goes and let you know.

    Alright...some first observations. There is great improvement in the battery life but it's still not what I would expect. Eg iT still drops during the night about 2% per hour. That is better than the 4% that was before removing KNOX of course. Something is still keeping the phone awake. I am wondering about two things: Firstly if all those Battery and Wakelock monitor apps are keeping the phone awake and if it would be a good thing to remove them and see what happens. Secondly, if it's necessary to do a factory reset (which I would hate to do, since I did it 3 times in the last few weeks). By the way, what is this Security storage that is using so much ram?Galaxy Note 2 - Massive battery drain after 4.3 update-screenshot_2014-01-17-03-12-27.pngGalaxy Note 2 - Massive battery drain after 4.3 update-screenshot_2014-01-17-03-12-48.pngGalaxy Note 2 - Massive battery drain after 4.3 update-screenshot_2014-01-17-03-13-14.pngGalaxy Note 2 - Massive battery drain after 4.3 update-screenshot_2014-01-17-03-13-34.pngGalaxy Note 2 - Massive battery drain after 4.3 update-screenshot_2014-01-17-03-13-46.pngGalaxy Note 2 - Massive battery drain after 4.3 update-screenshot_2014-01-17-03-14-06.pngGalaxy Note 2 - Massive battery drain after 4.3 update-screenshot_2014-01-17-03-15-19.pngGalaxy Note 2 - Massive battery drain after 4.3 update-screenshot_2014-01-17-03-15-50.pngGalaxy Note 2 - Massive battery drain after 4.3 update-screenshot_2014-01-17-03-16-04.pngGalaxy Note 2 - Massive battery drain after 4.3 update-screenshot_2014-01-17-03-16-13.png

    I noticed my internet security running constant. I believe that the security software is detecting a "bug" in the Android update and starts scanning continuously. Can overheat the batteries and possibly the processor. Try uninstalling your internet security. This solved my battery drain issue. Don't have a cure for the security issue yet. Not much help. :-/
