"wlan_wake" kernel wakelock high drain problem

Hello, I'm having a problem, my Wakelock Detector detects a lot of wake time (72%) by a kernel wakelock named "wlan_wake" and I don't really know how to solve it! I have a Samsung Galaxy S4 i9505 with the 4.3 android version, official release, and this started to happend less than a week ago. I cleaned cache and dalvik, I tryed to let the wifi always off, and nothing worked... Solutions?

Did you recently install viber ?
Viber is known cause of keeping wifi on while the phone is in sleep mode. you can easily Greenify it.

Go to settings wifi advanced settings and disable wifi search whlie wifi is off (sory dont know the right name because I use miui
This disables the search for wifi networks while the wifi is off its a know issue in android 4.3

It didn't help me!
but after restarting the phone the problem is gone. AND ITS BACK AFTER 2 DAYS!!!
EVERY TIME!!
Ohh yes.. And I know that if i turn of the WIFI the problem is gone..
BUT!!! I want the Wifi to be ALWAYS on..
Please help!!!

I would suggest doing a full wipe on your ROM or trying a different kernal. By the way, using CAPS and a lot of !!!!!!! will just make people not want to help you.

Same here. See http://forum.xda-developers.com/showthread.php?t=2533853

and it seems to be always occur after a application has updated through googleplay.

Android-System Battery Drain after Update to Kitkat

Hi There,
after I updated to kitkat, I have more Android-System drain then screen. Over 23% Android-System and round about 20% Screen.
With Jelly Bean I have had 50 % for screen and I could use my Phone for 3 days with normal use, 2 hours Screen ON Time per day...
My Phone is NOT rooted and I can't analyse the drain with wakelook detector.
Maybe anyone have the same issue with the phone and can help me to find a solution.
here a few pics from my phone and the Battery-consumption
excuse me for my bad English!
best regards

Solution is very easy. Factory reset your phone. NOTE: Files in Internal SD would be deleted too. So backup whatever you need, or everything in there to your PC, just in case.
Follow up with my battery saving tips here - http://forum.xda-developers.com/showthread.php?t=2579075

I tried before I post here. Doesn't help! ?
I forgot to tell, I use greenify und disabled a lot of bloat ware

With pure stock unrooted Kitkat, it seems Android OS/System sits around 17-25% average. You can limit the usage by turning off GPS and uninstalling Google Search / Google+ and switching off Google Now. Reboot into recovery mode (yes stock recovery) wipe cache and then boot up the phone again. Simple no bells and whistles tweak. It works.

Thank you for the answer!
This steps are already done. It doesn't help ?

[Q] Can't make or receive phone calls

I thought I had performed all of the necessary checks before flashing Cyanogenmod on my Note 3, but it turns out it hasn't worked 100% as planned.
Everything is absolutely fine, bar the fact that I can't actually use it as a phone. I'm able to send and receive texts and also use data, but whenever I go to make a call, the call ends and if someone tries to call me, they hear ringing, but nothing makes it through to my Note.
I found this post reporting a similar issue. I'm locked into O2 in the UK, so I'm guessing it's something along those lines.
Is there anything I can do to resolve this or do I need to restore to a backup?

Use a CyanogenMod build from 3/27 or earlier and you will have calling back. It's a bug that is still not fixed as of today

Thank you. I'll give that a go just now.
Edit: That worked. Thanks for the heads up!

Same problem here
Have exactly the same problem with SM-N9005 on Cyanogenmod Nightly 28/03 onwards, and can't dirty flash back to 26/03 somehow, have to clean install 26/03 to make the phone working again. Super annoying...

I know that feel, bros, but on a stock based rom it works.

Guys, everytime I flashed an AOSP based Rom like Carbon on my hltexx, nobody can call me and I also can't call someone else. If I dial a number, the connection seems to break instantly but my mom told me, she got my calls but didn't hear anything. I'm also unable to change or view the access points.
Stock based Roms like Omega work correctly.
WTF am I doing wrong? :crying:
Additional Infos:
>SMS and Internet work.
>3G because my provider (Drei, Austria) is retarded.

>restoring an old EFS backup didn't solve the problem

Update: after dirty flash the latest Nightly 2013-04-05, calling problem seems to be resolved. So far so good, fingers crossed. :thumbup:

App Back Up without rooting phone (using Carbon AKA Helium)

I would like to move my subway surfers progression from my S4 to my new Note 4. Another forum advised using Carbon (now changed their name to Helium) https://play.google.com/store/apps/details?id=com.koushikdutta.backup&hl=en_GB which I have used but now it says to restore data I must pay the premium (wish that was obvious before I wasted my time) but hey ho, I was going to buy the licence key but there were bad reviews saying it didn't work or messed up the users phone. My question is has anyone used it before or could recommend another app I can use to back up my app data without rooting my phone. £3 is a lot to waste on an app that doesn't work or can cause problems to my phone

You have a 15 minute refund period for all applications you bought on Google Play.
Try it and get a refund if it doesn't work.

I didn't have to pay anything to restore my apps using Helium. Just make sure the data is on the internal storage of the phone.

I used the free Helium to save my Apps and Data from Note 3 and restored successfully on Note 4

Could you explain this in more detail? I tried to restore from my old RAZR to my Note 4, but I couldn't figure it out. I saved to the internal storage, but I couldn't find the files.

Hmm the article is about bricked Phones after installing recovery or rom but i changed the rom very often and no brick or touch screen issue appears. The only issue in every rom is the rotation.
