I have sync off, maps off, gps off, location off... and wifi set to "never on" during standby mode...
But... it takes a good 15 minutes before wifi actually turns off, which wastes a little bit of battery life
Any way around this? Eg, make it turn off wifi quicker?

Uhmmm well maybe if you were able to provide more info like rom, rooted or not, kernel etc. we'll be able to help you out more.
As of now i can tell that is not right, mine goes off immediately.
Yes, more info would help however try this go to your settings and in the WiFi settings forget your network then restart your router and re-boot your tablet off/on (not stand by) then go to the wireless settings log back in to your network.

Well, because it is not a normal thing to happen. So if it is not normal, it is a sign of a possibly bigger problem that needs to be addressed. If he is on a custom rom, then the dev would be notified to see if its on his end, to fix in the next release. And those are just two reasons why people "care about such small things". Welcome to xda. This is where all the small things are fixed. Its kinda the point.
Are you sure that's not normal? All my android devices take 10-15 min to turn the WiFi off.
It'll have a negligible effect on your battery life but if you really want it to turn off faster, the green power app on the store allows you to turn off WiFi instantly.
That's normal. If you have tasker or other similar app you can set it to turn off WiFi on lock or if you have a magnetic case, sit it to turn off WiFi when it's closed.

Don't think that's normal, wifi always turns off almost instantly for me
wifi turns off almost instantly here too. 10-15 minutes to turn off wifi is not normal in any situation. op, maybe a little background? stock or rooted? rom/kernel? mods flashed? themes?
The WiFi on my N7 turns off instantly. It did when it was stock unrooted, it did when it was stock rooted, and it does with Paranoid Android. Not sure what the issue may be. Unless you are running a different kernel.
It is normal.
I'm on CM10 and in the advanced WiFi menu is an option to alter the default WiFi timeout from 15mins to other values. I'm unsure if that option is only available in CM10 but I think its also available in stock, can someone on stock clarify that.
The advanced menu is definitely available on stock 4.1.2 I'm just unsure if the timeout is configurable or not.
But WiFi always takes some minutes to disconnect in case you decide to hit the power button to put the device on standby and then 2secs later decide to use it again.
Test it by just hitting the power button and 10secs later hit it again and look at the WiFi icon, it will show its connected. Now do it again but wait 20mins and then hit power and look at the icon and it will show its disconnected.
I guess the timeout can be affected by apps that use WiFi when the screen is off and how quickly the device sleeps when the screen is off etc.
Stock, rooted. Using Notification Toggle, my wifi turns off immediately when I touch the wifi toggle icon.

Is the concept of this thread that hard to the understand...
...of course it turns off immediately if you hit a toggle, that's the point, this post is about the timeout value, ie the WiFi timeout when the screen is turned off.

It seems like after, I don't know, maybe 5-10 minutes or more of the phone being in sleep mode, when I unlock the phone and go to do something, like check mail, or hit a website, the WiFi is always showing disconnected. Wifi Logo with the Red X over it in the upper left of some Roms.
Then, it jumps and tries to reconnect after a few seconds and shows the normal connection icon bars onthe right. Kind of frustrating waiting 10-15 seconds for it to reconnect.
Is this normal?
Every Froyo build I have tried (three different) have this same behavior. It seems the WiFi is disconnecting itself while sleeping. Then once awake again, it connects back to the access point.
I can't find any setting that seems to be affecting this.
Anybody else have this issue? Is it by design?
Thanks
Search didn't help? Really, this was brought up a lot.
Press "menu" when in WiFi menu, I bet you can take it from there.
Ah, and look in the Apps section, first page will probably help you, if the suggestion above didn't.
No setting?
How about Settings->Wireless&networks->Wi-Fi settings->(press Menu)Advanced->Wi-Fi sleep policy?
(and yes, I do agree, they shouldn't hide an option like that behind a menu in settings, think that's the only setting screen with a menu)
The wifi sleep policy is broken is some phones. See this thread:
http://forum.xda-developers.com/showthread.php?t=706454
or google it, there's a bunch of people complaining about it for a long time.

This option is no guarantee..unfortunately (there´s a bug in the OS)
Haha...what a tool I am. Could have sworn I looked in the menu and didn't see that option.
Will give it a go and see if it works and not a bug like some have had with it.
Stupid policy by the way by default to set it like that. Kind of like when closing the lid on a laptop running Wiondows. It goes to sleep by default?!?! Ok.
My searched terms must have sucked also...I went through pages and couldn't find this.
Thanks.
I noticed people are using power management apps to "fix" the SOD in CM7.1. I use green power myself, and it works great. Stopped my SOD's completely.
I ran across this thread to fix a wifi off at screen off issue. http://forum.xda-developers.com/showthread.php?t=774507
It seems the default wifi off at screen off is timed at 15 minutes after the screen turns off. If we could have an option under cyanogen settings, or advaced wifi settings, to change this timer to just a few seconds, I think it could temporarilly fix many of the SOD problems, until the real culprit is found. I know Dalingrin said he would get to the SOD problem after a couple of other projects, but maybe this could be a temporary fix until he really gets into it.
I would have put this under the developers thread, but I read a lot, and post a little.
What do you think?

Just use Setting Profile Lite or Tasker or whatever to turn off wifi at screen off and back on when it's back on. Doesn't seem like adding a setting in CM7 to set the length of time is worth it.
This is the part I'm not quite following...the behavior you're describing (wifi off with screen and on with screen) is actually the CM7 default, so why the need for a special app?

I haven't looked at these 3rd party apps yet but I don't believe shortening the wifi sleep timeout would help. I believe the reason these apps prevent SODs is because they forcibly turn off the wifi after some time. There seems to be some condition that the wifi driver or wpa supplicant gets locked and the sleep timeout has no effect.
What is the default time period before wifi turns off when the screen turns off?
I am noticing people in the various SOD threads having success stopping their SOD's with third party software that does what the advanced wifi setting "should" do, cuts the wifi off when the screen turns off. I am using "green power" and set it to turn off wifi 5 seconds after the screen turns off, unless there is traffic. I have not had an SOD since. The thread I linked to says the default android time period for wifi off is 15 minutes.
Maybe, just maybe, SOD's are occurring in this 15 minute time period. That's why people are having success with these 3rd party apps.
This was a reply to rhester72. I should have quoted.
Dalingrin, Did you happen to read the thread I linked to? It may be of some use to you. It may not. It may not pertain to your kernel.
I'm no Dev, just someone that appreciates the work you do, and am trying to help.
Well, I guess I learned something. WiFi off when screen turns off, in the advanced wireless setting, does not actually turn the WiFi off. It only puts it to sleep.
The third party apps that turn WiFi off when screen turns off, actually turn the WiFi off. That's why they "fix" SOD.
I'm still curious as to the default WiFi off/sleep when screen turns off timer is. Just for knowledge sake.
Thanks again, to all of the Devs, for all of your hard work.
Well, interestingly enough, I updated from n150 to n157 last night and this morning after disconnecting from power (with wifi set to never sleep when plugged in), about 5 minutes later I had my first SOD in a *long* time. Not running any special power-management apps.

My NC hasn't had a single SOD since selecting the option to turn wifi off when screen is off. Surely, unless you need notifications while the NC is in sleep, this is the simple solution to SOD?

Hello,
Coming from WM and WP7 i am crashed with so many apps for my Note.
I am searching for a way to disable the WiFi when the phone goes to standby.
Maybe one where i can set the time between screen is going black and disabling WiFi?
Any hint or guess?
Thanks in advance
Juice Defender will do that for you:
https://market.android.com/details?id=com.latedroid.juicedefender&feature=search_result
But you don't need a special app for that. It can be also done via WiFi advanced menu:
Settings/Wireless and network/Wi-Fi settings
Once in Wi-Fi settings, click Menu button (the bottom left one), then click Advanced, and you'll see Wi-Fi sleep policy. Click on that and select 'when screen turns off'.
You're done.

On every page it changes the options available, great!
Thankyou very much, the battery drain was significant with WiFi allways ON.
wow I never know it's have this option...
I think android need to display some hint to us that some page have more config menu lol.

It's a good option to have, but I find there may be a considerable lag between screen off and WiFi off. That may be just after changing the settings, I have yet to see. You can compare by looking a the battery usage, and clicking on the graph to make it full screen. Then you see the screen and WiFi 'on' periods below.
I found that by enabling the option to "when screen turns off" it drains the battery much much more then when it was on "never". Could this be because it is always searching for a mobile network when display is off?
I find it much easier to use the notification bar to switch off wi-fi just before I turn the screen off. It's become such a habit that it doesn't bother me. At least I know that it is 100% off and is not draining my battery.

Two things:
1. I have read that too. I am not sure. Now I use Llama to turn off mobile data when I am Home or Work, where my WiFi networks are. It also turns off WiFi when I leave either place, because I always forget. I think that may help.
2. When I set WiFi to sleep when the screen is off as an attempt to increase battery life, I get the issue in the battery graph that WiFi does not seem to always turn off. I would have expected the blue bar for WiFi to be off when the blue bar for the screen is off, but it just seem on most of the time. Sometimes it does turn off, however.
This happens whether I let Llama set it, or I set it manually. Seems flawed to me.
Same here, wifi never turn off with screen. have to disable manually, otherwise battery drain.

You can try "Green Power" app
I use this app to manage the WIFI and Mobile Network
It really saves the battery...
thx, i'm trying it...
There is something you can edit in some database. I cannot find the post again.
I have solved the problem by getting Llama to turn off the WiFi 1 minute after the screen is off (that can be adjusted, obviously), and turn it on when the screen turns on. WiFi usage goes down significantly. I have yet to have a 'slack' day, so am not sure of the overall effect.
It also keeps the WiFi on if charging because I have set SugarSync to only sync while connected to mains power (a really useful feature). That way I get the best of both worlds.
Hi all
My Wifi stays on during sleep even though in settings I have this option set to never.
Anyone else experienced this? And is there a way to make the Wifi go of when n7 is in sleep mode?
Thanks

Have you actually given it time to turn off? Not sure if it is 5 or 10 minutes but for me it eventually turns off.
EDIT: I am set to "Only when plugged in"
Or there is a build prop tweak that suspends it in sleep like pm.sleep_mode=0 or close to that
Sent from my VS920 4G using Tapatalk 2
The N7 wifi stays active for several minutes after the unit goes to sleep - even if you have it set to be only on when plugged-in or off when sleeping.
This is a really stupid design so I use my wifi widget to just turn it off before putting the unit to sleep.
There's most likely a setting somewhere to tweak to get the wifi to turn off immediately when the tablet sleeps.
Yes, the built in wifi off at screen off sometimes takes minutes and sometimes never turns it off.
Green Power, Tasker, Settings Profile, etc, all market apps will turn off wifi for you on screen off.
I use Tasker myself.
Hey so my night clock is set but doesn't activate unless I reach over and swipe the edge. Which defeats the purpose. Then it turns on and stays on but will not just turn on at the set time by itself. Am I missing something or is it just a random glitch?
Thanks ya'll

OK. The only other thing I would mention, is the clock won't show automatically unless you swipe, when the battery is low - I believe at 15%. Do you have any power saving modes on by chance?

I believe so
I can't remember my settings on that. I'll have to double check but my battery is never that low when I'm sleeping. In fact, a lot of the time it's plugged in.
