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.
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?
Did you use throw or media share?

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).

Getting some heavy wake locks on the one all of a sudden.
My phone also oddly enough seems to be draining battery faster with the screen off than on.
Question I have for you is anyone familiar with this wake lock / alarm.
android.content.syncmanager.sync_alarm
Showing as 1300 wakeups. Does this have to do with HTC sync manager? Heck I don't even use it.

Looks to be stupid Google plus.
I set a custom reference and right away it had the sync alarm wakeup.

I'm a bit confused here...I use GSam Battery Monitor to keep track of everything b/c I'm anal about whats running on my phone and lately, if i check "Time held awake", voicemail is number one...like today...2h 59m and the phone has only been off the charger for about 7 hours....does that make any sense??
Voicemail is in the top 3 of power used at 12.9%...If i check "number of times waking device", voicemail is nowhere to be found in that list...
So is this normal or is something crazy going on?
Wakelock Detail:
starting cm_vnote service 1h 31m
cm message wakeup 1h 29m
18 wakelocks.
Is this a visual voicemail app that came preinstalled? If so, disable it assuming you're on Android 4.0 or above).

Mine has been awake since I unplugged. I would guess the reason were not seeing the times waking the device is because it's not waking it, it is holding it awake.
I'm on vipers newest, and this did not start until I switched to his newest. But I am always deleting useless apps, I wondervif your are doing the same?

Why not just use Google voice? When you set it up it will disable the Visual voicemail app.
Or you can just freeze it and I'm wondering if you can use the pm disable command to disable it

Just got my Dev edition. Upgraded to 4.4.2 and after a while to 4.4.3
All seemed fine until i noticed that Google play books used 40% of the battery... Weird since i opened it, scrolled the list and closed... It wasn't even in the recent app list...
I killed it and added to the disable list (i use fbreader anyway)... Now today (second day with phone) the same happened with YouTube...
It used 30% of the battery. I watched a10s clip... App info said 10s foreground... 30 min background... And again, it wasn't even on the recent app list to be closed. Just went to apps and force closed.
Now I'm worried that this is a thing with everything Google (which honestly i can disable all but gmail and maps) or the OS...
Anyone getting the same? I'm not sure what to search for to find similar threads...
I'm guessing this is either common or i have a ducked device since i got it twice for the 2 days i have it...

Ugh that's really weird. If you're rooted it will be a lot easier to fix but for now reboot the phone and use it like that for another day. Sometimes the OS and apps need time to settle. For example I did a fresh flash two days ago and my Google services had a 1 hour and 13 minute wakelock yesterday where as today it's behaving very well. But YouTube doing that is weird. Never auto update your apps as 85% of updates are crap across the board. Try going to apps under settings and click uninstall updates for YouTube. This should revert YouTube to the version that came with 4.4.3, unless that's already the latest. But yeah for now try and "tickle" YouTube by logging out, wiping cache and data for it under settings/apps and log back in, see if it starts behaving. I'll monitor this thread to try and help.

Thanks. I did all that yesterday and rebooted. So far everything seems fine. So i think you're spot on. Tho it is a bad sign to have those bugs
The phone did lock up twice on me after that.
Once playing webm on chrome. But i just disabled it a while later. Firefox beta ftw! ( ff is the Only reason i have up my nexus one)
Another time when i inserted the Sim with the phone on and right away unlocked the slider... It froze mid slider animation. Think i hit some race condition there. Hopefully i won't be inserting sim cards all the time...
Overall i think i will be able to live with that phone. Now only if i could use nfc unlock with my assine employer email policy...

It may have happened again. It's reporting a widget (simple calendar) as using 15min of cpu with 4min of foreground time. I had opened its setting screen 15 min ago. After i liked it from the recent task list it stopped counting new cpu time. But it's still showing as the top battery user for now.
Since that setting screen has ads, i will just write this off as a sleazy ad library for now.
