I have a 2013 Nexus 7 32GB and turned off "scanning always available" option (let Google's location service and other apps scan for networks, even when Wi-Fi is off) and set "Keep Wi-Fi on during sleeping" to never.
The table should not turn wireless off and on during sleeping, right?
Look at the attachement and the power meter shows that wifi turned off and on while the screen was turned off.
I didn't have this problem with 2012 Nexus 7.
Is this a bug with 2013 Nexus 7?

Other apps can turn on WiFi. Maybe its an installed app?
I had a similar problem and used Greenify to hibernate several apps. That solved it for me.

Try turning off wifi optimization. That's how mine is configured with the rest identical and wifi shows solid.
tried the above but still didn't work. I'll try wakelock detector and upload screenshots.

my wifi connection always drops after few minutes and then it tries to authenticate again. this happens when i left the phone idle for <3 mins or so and sometimes less. when it tries to aunthenticates back, it takes a longer time than just simply turning off and turning on the wifi back again to get connected.
is this an error or its just the way the phone is? i'd like to keep my wifi connected during some heavy downloads and be able to leave the phone lying somewhere while its downloading..
explainations and help needed..
you not using any power manager apps that turn of the wireless after the screen switches off when left idle ?
And what about wifi sleep policy? But there is problem for me too. I turn it off, but when i disable wifi, and turn it on again, wifi sleep policy settings are again at 15minutes.

i'm using Advanced task killer and Android booster on my phone to kill running apps. however, i did not used them to manage my power consumption. i have not done any settings regarding wifi connectivity on both those apps. But could both these apps be responsible?

my wifi sleep policy setting is set to Never by default. Could it be my router whose causing this issue?
Is it possible to have a Hibernate/Standby mode on the Transformer? Not just a screen off setting. I am used to putting my netbook into standby, hitting a key, and everything ready to use within a few seconds.
With the current screen off setting, the wireless stays on, I stay visible on gTalk and messages end up going to my Transformer instead of my phone. Also, I would think battery life would be increased.
I would check your settings as my wifi disconnects when screen off
settings located
Wireless & Networks
Wifi Settings
Wifi Disconnection policy
mines set to When screen turns off
Not sure about Hibernate state on android at all others may know

Did not know that. I had just been turning wifi off because I noticed that even withe the screen off it was draining the battery faster with with with wifi enabled.
While I'm downloading a large App if I put my Nexus 7 in Standby mode will the WiFi still be active and keep on downloading the App? If not how do I turn off the Nexus 7's screen while downloading a large App thats going to take a while?
You have to set Wi-Fi to stay on always. It's in Wi-Fi settings.
Sent from my Nexus 7(2012) that has zero issues.
Noticed in battery settings that my Wifi turns on and off frequently even when my device is sleeping. Doesn't seem to be affecting battery life but I'm wondering why it does this. It happens on both my Nexus 7 (stock rooted) and my Nook HD+ (CM11). I do have the "always scan for networks" settings off.
Attached screenshot is after I didn't really use my Nexus 7 for about a week.
I would imagine this is caused by certain apps requesting data. For example, your Gmail app may be set to refresh every one hour, which means it needs to use the WiFi to search for new data and download it, if needed. Other apps are similar to that as well, depending on your settings.
If it really miffs you, you can always use tasker and create a task that shuts the wifi (I have it put it in airplane mode since it does several things in one shot) off when the display goes off and back on when display comes back on...will need to be rooted.
I got my 6p last week and it's been running great until this afternoon. It got warm and the battery level drops by 70's at around 10am to low 30's at 4pm; during that time it was mostly on airplane mode with all sync/bluetooth/gps turned off.
When I checked the battery history it says that the GPS has been on for over 7 hours. I certainly did not turn on the gps myself (I turned off location), and I do NOT have smart lock.
Question: How can I determine which apps/processes turn on the GPS?
I also notice that "Miscellanenous" is responsible for 29% of the battery use.
Question: What the heck is that? How can I turn it off?
Thanks!
Try disabling the GPS in settings.
I believe your issue stems from Wifi not GPS, anyhow try this - turn off WiFi scanning, and turn off the option to continuously scan for more accurate information. I had similar issues before I turned this off, my battery used to drain a lot on Wifi.

Thanks! Where do I find these options for turning off wifi scanning & for (not) continuously scanning for more accurate info?
Under wifi-->advanced wifi I already set "keep wifi on only when plugged in". I did turn on "notify whenever a public network is available" --- is that what you meant by "wifi scanning"? But I can't find anything about "scanning for more accurate info" (I already turned off location and smart lock).
Thanks!
EDIT: I just realized something: The compass on my 6p has not been working properly (see http://forum.xda-developers.com/nexus-6p/help/compass-t3243394). This morning I spent a good 10 min calibrating the compass by doing the figure 8 dance etc. It didn't fix the compass, but the time where I began the figure 8 dance roughly coincide with the time where the GPS was reported to be turned on... The plot thickens...

Are you even using this device or android M or you just giving advice from android kit kat? There no longer is "turn on/off scanning" in android M.

There is no plot. Just find which app runs in the background and continuously asks for location. Problem solved.
