turn off WiFi?

guys, is there any point turning off WiFi when not in use, or does it do the decent thing and stop using power when not actively in use?

I'd imagine it still scans for networks so it will still use battery - I just have the toggle on one of my home screens and turn it on when needed

from Market, get WiFi Status from Andrew Schwimmer, one of the very best android app developers. It doesn't do exactly what you want but it's the smartest detection app out there for letting you know when there is no wifi signal to connect to, thus prompting you to toggle off wifi. It displays in the Notification Bar.
As for turning off wifi, I tried about 10 home screen widgets; they are all the same more or less. To me the far greater tool is Quick Settings, which gives you one-click access from anywhere via the Notification Bar, vs having to navigate to home screen and find the widget. But in addition it has toggles for sound, brightness, data, gps, bluetooth, etc -- all in on fast app.
I think it blows all these single-function widgets away as dumb.

So if my phone is on, screen off, in my pocket, it'll be constantly looking for wifi? If this is the case it's, well, dumb. Ta for tip about quick settings, just installed it and it's very nice.

Not sure it would be scanning for wifi when the screen is off. That would be daft. Ntework coverage yes, but wouldnt think wifi until you turn on the screen. Anyone confirm?

no, it stays on when the screen is off.
Seems so many people complained about it turning off in standby that google went ahead and changed it.
now it defaults to staying on forever until manually turned off.

Go to Settings> Wireless & Networks > Wi-Fi Settings > [Menu] > Advanced > Wi-Fi sleep policy. I set mine to 'after 15 mins'... if I understood this setting correctly then after 15 minutes of the phone being in Sleep mode it'd turn off the Wi-Fi. I don't use mobile data anyway so that's irrelevant. Wi-Fi will turn on again once I activate the screen.

blimey, that's well hidden.
what a stupid arrangement. WiFi should be on demand, and enabled only when data requests it, like the iPhone.

I use "Y5 - Battery Saver" for my wireless shenanigans

I am using 'Y5 battery save'r. It turns on wifi if you are on a location where you had a wifi connection and turns it off if you go elsewhere. You can manage the locations in the program. It can use the GPS or radio for the locations. You will find it in the market place.

Problems: Wifi keeps turning on and off when screen is off

Hey there,
I'm using S-off and oxygen 2.2 on my rooted desire and I have a big problem:
Always when I press the power button so that the screen goes off and than turn it on again by pressing it again after some time (20 secs or so) I see that wlan is turned off and the cellular data connection is used. Shortly after the screen went on, WLAN is on again. Is this some default behaviour to save battery? Is wlan really more battery comsuming than the providers data connection?
The problem which arises now is: I'm using http://www.appbrain.com/app/unlock-at-home-using-wifi/com.accedo.unlockathome which unlocks in a certain wifi and locks, when going out of whitelisted wifi networks. When I press power to turn off the screen and the wlan is disconnected after some short time, the screen gets locked and somehow I think that the screen gets on shortly after this. This causes the wifi to connect again and than after turning off again the wifi gets disconnected again. Thus after the lock applications locks the screen and thus shows it again... -> infinite loop. every now and than (i think about once a minute) I see the screen go on and quickly after it off again.
how to fix that?

Do you have something like Juice Defender installed?

Check the sleep policy.

Set wifi sleep policy to never, under wifi advanced settings.

Nope i havent!
@k3lcior: strangely it's already set to never and though I often see the cellular data icon appear also when I use the phone (e.g. when writing an sms) and directly disappear again there's to be a problem I think with something on my phone!?

WLAN off when Screen off?

Hi,
I just discovered something strange: I use FolderSync to sync Music to my GN. I configured it to only sync when WLAN is available. When I sync and switch the screen of, then the Sync stops immediately and resumes when I switch the Screen back on. Is WLAN switched off when the screen is switched off? Did I miss some settings to configure that?
Thanks

May be related with some auto task killer or process killer like juice defender

Yes you missed some wifi settings. You can set there whether you want to turn off wifi with the screen, keep it always on or keep it always on while charging.
You can find it in:
Settings - wifi - ... - advanced

Thanks martan1981, but this is "always on" on my GN. So thats not the reason

Do you have any battery-saving apps like JuiceDefender or GreenPower installed? That could cause your data/wifi to turn off with the screen.
Or there could perhaps be a power-saving function built in to your ROM? I know AOKP has a Power Saver mode that could be enabled to turn data off with the screen.

wifi sleep policy should be set to never. But some people have a bug where this setting does not stick for some reason. You prob have this bug too.

I also have this problem how to fix it ?

[Q] Wifi won't connect until turning on screen

My WiFi doesn't seem to connect to saved hotspots until the screen is turned on. Whenever I get to work or back home and I don't turn on my phone; a couple hours later when I actually turn on the screen it connects. Does anyone else have this issue or know what might cause it? I'm not using any power saving apps or any apps that affect my network.

Try going into Settings-> Wifi -> Click menu button and select "Advanced" and make sure "Keep Wi-Fi on during sleep" is set to always.

It's already set to that. Any other suggestions?

can anyone else verify this happens for them too? I have tried a complete format/wipe and loaded a stock 7105 rom and am still having the issue.

Maybe if you have power saver on, it does that? I know it's lot listed under what it's done, but you never know (;
Other than that, I can't think of anything other than keeping WiFi on during sleep.

it's off :< My roommate's S3 and my other roommate's N4 both auto connect without touching the phone. Once you turn the screen on it's already connected to wifi while mine is on edge until I power on the screen.
The only reason this is an issue is that I use grooveIP for calls through data, so if I have no reception here (i.e. no data) I won't be able to reliable receive calls unless I remember to power on my screen every time I come home.

WiFi Woes & Power Saver Problems

Having just returned to the latest stock firmware after a couple of weeks testing CM12.1, I am finding that even if I turn "Keep scanning on" off in advanced WiFi settings menu, it comes back on by itself. Also, when I check my battery stats, it nearly always seems to show a solid bar for WiFi regardless of whether my WiFi was turned on or not, regardless of whether always scanning is on or off, regardless of whether location is on or off... it seems to have no effect whatever the settings are.
I am also unable to use the Power Saver function. If I try to open it, I get the "Unfortunately power saver has stopped" message. I read that disabling the stock clock or calendar apps causes this problem, so I deliberately didn't do so. Are there any other stock apps that will stop power saver from working if disabled? I guess I may have to enable everything again and then disable one by one checking power saver each time to find the culprit, but that is a huge pain in the behind, so thought I'd ask you guys on xda first
