nexus 7 not killing wifi during sleep after updating to 4.2.1

I have selected to never keep WiFi on during sleep yet now the tablet continues to run the WiFi as you can see in the pictures. This has forced me to use airplane mode when I am on the go because otherwise the tablet just keeps WiFi on and burns the battery extremely quick. This has been a problem since I updated to 4.2.1. I am not rooted completely stock. A solution would be great because this sucks right now. I have tried clearing the cache in recovery but that didn't solve the problem.

I'm running the latest Paranoidandroid ROM and thought that was the problem. I can't yet post to that developer forum so I was just waiting for the next beta.
I guess it's a problem with 4.2.1 then.

If you don't find a solution you may want to try DataEasyPro from the market. It kills both 3g and wifi as soon as the screen is off and then runs a user defined schedule to turn on 3g or wifi every now and the for a few seconds to keep you upto date with your social world. Works great. There is even a widget so you can turn off the schedule when you are downloading or updating from the play store.

I think it is a 4.2.1 problem. Its hard to say how wide spread it is though because I have only seen a handful of posts about this issue though. To me, this issue is unacceptable. I should not have to enable/disable airplane mode to conserve battery. Especially when the previous version of android prior to the 4.2.1 update handled WiFi sleep settings without a problem. Hopefully a fix will be here soon. My tablet used to have superb battery life without me constantly monitoring it. Now I feel like I have to keep double checking that I remember to use airplane mode so that I don't go to use the tablet and find a nearly depleted battery.

I recommend automate it, I have a couple of rules set to turn WiFi of with the screen (with a 5min delay), then turn Wi-Fi back on when the screen turns on. There's plenty of other settings and rules to play with as well.

In had the same issue. I found Google maps to be the culprit.
It defaulted back to location reporting.
Check Google now sync, maps and currents.
Sent from my Nexus 7 using xda app-developers app

It's not google maps itself, it's the android location service. It's always collecting data even if your phone or tabscreen isn't on. This is pretty anoying since google only let you choose between agreeing to run the service in the background or not using it at all. Stupid! How about collecting data only when the device is in use?

Same here. There is a bug report on Google about it.

Ah this is interesting; as last night my battery was on 53% and I am sure I charged it fully previously...... Am on stock too but have rooted.
Might just switch the tablet off all the time for the time being.

I'm on stock rooted 4.2.1 and mine is fine. Strange.

WiFi turns off here also, which means its working as intended, what is strange is is it not working for some people, I'm also on stock rooted 4.2.1.
what is the OP using? Are there any apps installed/running on the OPs device that can keep the WiFi alive?

I highly recommend using an app called Better Battery Stats. You can find the free version here on XDA. It'll tell you if there is an app causing a wakelock. I used it to troubleshoot my Rezound and I'm getting a solid 4-5 hours of screen on time with the extended battery on that because it helped me lock down the apps that were killing my battery.

Hmmm. Just checked PA beta 7 and it's doing it too. Wifi on always.
A custom kernel would probably fix that.

I was having the wifi on issue as well. Just bought my N7, stock 4.2.1 and not rooted. I followed the tip in point four of this post, which details a simple set up using Tasker, where the unit turns the wifi on and off after the screen turns on or off respectively. The reason for the 10 second delay as is detailed in the link, is to allow for the turning on of your N7 to check the time or other reasons, and then quickly turn it off without the wifi on task being activated.
the screenshot below shows my wifi being stuck on while in sleep mode, even with it set to be never on during sleep in the settings, and the change in behavior once the 2 Tasker profiles we set up.
Cheers

Those of you having issues, have you tried the "only when plugged in" setting? Not sure if it would really matter but that's what I use and mine turns on and off just fine.

Testing that now. Turned off Tasker, and set wifi to the "only when plugged in" setting. It's only been about 30 minutes, but so far it looks like it's behaving the same as before, as in keeping wifi on while in sleep. I'll Let it sleep for a few hours and see what the chart shows.
Cheers
EDIT: So I let my N7 sit for about an hour after switching the above mentioned settings, and you can see in the screenshot below that the wifi is staying on while the unit is not awake. I've set my Tasker profiles to control the wifi once again.
I know it may be fixed by a factory reset, but frankly I'm more than happy with the way Tasker handles the issue.
Cheers

so 6 months later, I am still getting this problem. However it seems only to be with the last update. The tasker method seems to be working well though.

AW: Battery drain
It's the mediascanner.
The mediascanner introduced in 4.1 does not like many files and a cluttered folder structure. If you've migrated your sdcard from an earlier device, it's time to de-clutter your folders, get rid of old junk and make everything lean and clean again.
The mediascanner also tends to crash and hang on corrupted media files. This will result in the phone heating up and battery going down the drain.

I have no sd card yet.
Gmail isn't the problem.
Mediaserver is still draining my battery.
I copied some songs and pictures from my other HTC device to the Z.
Can this be the problem?

Remove your multimedia files (music, video) and observe for a couple hours/days. If it recovers, check your files. If it doesn't change, theres obviously a need to look into the matter a little more indepth.

Mediaserver is probably audio playback service, it is differ from Media Scanner. Since Media Scanner is called as "Media".
edit:
To OP:
Here is my Xperia Z battery usage, I found that Mediaserver will keep running when your phone is playing "sound" (including touch sound, typing sound).
Since after turning off "Dial pad touch tones, Touch sounds", it is not running unless I'm playing music.
Sorry for my bad English.

Anyone else has the same issue with Mediaserver?

First thing I do. Hence I never have it.
On CM based ROMs this translates into Audiut wakelock which is triggered by UI sounds, dialer touch sounds etc.

Never mind.
Maybe those "Dial pad touch tones, Touch sounds and lock screen sound" are just one of the reasons that lead to battery draining problem. I don't know (maybe there are multiple possibilities lead to the same problem).
Anyway, if I don't start up any music player, the process does not show up in battery usage (at least up to now ).

When I use Walkman or dial touch sound or any sound thingy-Mediaserver % goes up.
I'm only curious is this normal or not?

I don't know but I never disabling /Location services (on any phone)
But yesterday I did and the battery performance jump up to 25%

Second time I charged my Z,i'm getting better battery stats.
I turned off my locations,dial pad sounds,dock vibrations.
And every time I turn off my screen I turn off my apps too.That helped.

[Q] Devices is keeping device awake? Is this DLNA? Can I disable it?

When using the phone with 'Stamina Mode' switched on I got the message that the phone was kept awake because of 'Devices'. I went into my Pwer Management > Battery Usage, and to my surprise Devices is at the top of the list, it has used 19% of my battery. It has a red icon (round circle) with a 'Movies' pictogram in it. The information about Devices is the following:
Code:
CPU Total: 12m 58s
CPU Foreground: 0s
Keep awake: 2h 33m 48s
Data sent: 2.98MB
Data received: 9.30MB
When I open Settings > Apps > Running and look for 'Devices' I find three services: DlnaDmsService, PushDerviceImpl and UpnpServiceCp. I also find the com.sonyericsson.dlna service. Does anyone know why dlna is running on my phone, even when I'm not connected to WiFi? What could be causing the wake? I do not have dlna enabled, and I think 'Devices' is a strange name for an Android process, especially with the Movies icon.
TL;DR:
What is Devices, why iis it running when I'm not on WiFi, and Can I disable it permanently?

I have used throw once on a Bravia TV, but I have turned media sharing off after that. This was about a week ago, and I have rebooted the phone at least two times since. My bluetooth headset has been connected for about an hour, and when it connects it is in the 'Throw' list. But is this a reason for the phone to use CPU wake time when WiFi AND Bluetooth aren't even connected?

Noticed mine was doing the same since yesterday over 45% battery useage for Devices.
I did work out how to use Throw yesterday, cant seem to get it to stop now
Just done a power volume+ reset and see if it clears up
If you refresh batter stats - the "Devices" changes to com.sonyericsson.dlna for a fraction of a second

Yup this is what kills Stamina Mode if you use throw you're phone will be like this for a while. Even when you turn all the auto stuff off it will happen again when you next throw. Hopefully it will be fixed, if not then it settles down again after a day or two.

But does using a Bluetooth Stereo Headset qualify as 'using Throw'? Because it shouldn't have anything to do with dlna, right?

It has happened to me once when I've used Walkman but I haven't managed to replicate it, but Throw it has done it to me repeatedly.

Hmm... interesting. Thanks for sharing your insights! Tomorrow I'll disable the 'Devices' application and see what it means in terms of battery usage and loss of functionality. I'll report back at the end of the day.

Today I disabled Devices. Bluetooth worked as it should, and my battery is at about 56%. I guess it's okay if you don't use DLNA. Of course this is all subjective, but I do think that my battery is lasting a little bit longer. If you're not using throw I recommend disabling Devices. You can disable it in Settings > Apps > All > Devices > Disable.

Stop Throw
So, anyone knows how to totally stop Throw???
No matter what I try, I keep getting the Throw symbol in my status bar.

No and I would like to know this. Seems like when you load it once, you're stuck with it (unless you disable).

Xperia TL "Android System" using tons of the battery.

So ever since the JB update, I've noticed that the Android System is using up a good chunk of the battery. The phone seems to be "waking up" constantly. Anyone else have this problem?

Let it sink for a week or so then it normally should go down.
Sent from my LT30p, 4.1.2 stock, DooMKernel v7,root access, unlocked bootloader.

Alrighty then. Thanks for the advice

I have had JB installed for almost 3 months now and it still sleeps very bad. Android system is around 11% in the android battery stats, i guess that's normal, but i just cant figure out whats waking up my device so often. I was so desperate to get it to sleep properly that i disabled auto sync, restricted background data for most apps and i disabled a lot of 'm. that didn't work. The highest wakelock in bbs is audioOut_2 but there's no real answer on whats causing this problem (for some people it's viber but i'm not using that) does any of you have the same problem? My drain on 3G is more than 3%/hour, that's way more than my xperia arc used to have.

I've been reading around forums and stuff. Trying to gather any information I can. From what I've read, it's just a bug in the Jelly Bean software. But of course, it could also be an app that is causing the wake ups.

In sound settings disable the last 4 options. Touch sounds and vibrate on touch and screen lock sound.
That will most likely fix your problem.
Please keep us updated.

1. turn off "Daydream" and "Glance" by setting--display
2. do not use "live wallpaper"
3. always use animations on "0.5" --settings--developer options
4. turn of "always awake" -- settings--developer options
5. set ur brightness low as possible
6. use apps kill app like "quickly recent app" and close all apps time to time.
7. turn off GPS and Data (when u dont need).
(For long life battery, use specific battery charger, lets the battery drained minimum of 4% then charge "if possible switch off the device and charge it".

Thank you all for your help. I had to freeze the stock messaging app using titanium backup to solve the battery drain issue. I'm currently using an alternative app.
