Does the blinking icon actually affect anything you're doing? Does it cause an interruption to the webpage or anything?

Yea it does... it interupt the webpage im loading...

Try booting into recovery and clearing both cache's(on two different screens) My WiFi was scanning every few seconds and interupting web and also turning my screen on after I would turn it off...no more problems now!

Try setting the wifi option "notify me when any network is available" to disabled.

Disable WiFi in Standby

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:

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.

Oh yes, stupid me, the menu button at left bottom corner!!!
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.

The one thing I dislike about my N7

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.

Wow, why do people care about such small things? It's not like it drains half of your battery.

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.

Nfc spontaneously shut off? Location setting revert to GPS only?

Ok, so I've had the phone for just under a week. I really like it. However, I've noticed that nfc will spontaneously just shut off on its own. I do not have power save mode activated. Similarly, I toggle location on/off often from the notification drawer, but I had set the setting to "power saving" where it estimates location based on mobile/WiFi signal. However, I often find it reverts to GPS only. Anyone else experiencing this?

Is WiFi on or off?

So I turn WiFi off when I leave home to go to work in the morning. See attached. It appears that WiFi is still on well after 9am. All the way up until I reboot the phone in the afternoon. Then is appears to be off until I turn it back on at home. Any insight?

go under wifi settings and make sure scanning always is turned off. that setting will make wifi stay on even if you turn it off.

On the picture you have, it's on.
To turn it off, swipe down from the status bar twice, and tap on the WiFi icon.
Or go to Settings, then Wi-Fi and slide Wi-Fi to the left

Thanks, I am fully aware on how to turn it off, and I do just that. My question is why does this show it was still on that whole time?

perfect. this seems to be it.

Also make sure that "Always allow Wi-Fi Roam Scans" is unchecked under Developer options.
