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.

Weird WiFi/Data issue

So I notice this occuring on Gingerbread, as well as ICS 4.0.4...
I usually have WiFi calling enabled because I use it in my house, and at my office. The problem is when I leave my house or my office while WiFi calling is enabled, it will not switch to data automatically unless I press the power button to show the lock screen. Then the data works fine.
Does this happen to anyone else? Is there a work around?
I have my WiFi set to always be enabled even during sleep.

Try toggling airplane mode instead of rebooting

I never said I had to reboot. I just have to press the power button to wake up the device in order to get service again. It's like it stays stuck in WiFi whether it's connected or not.

Check your advanced wifi options - hit the menu button when in regular wifi options - and see if keep wifi on during sleep is checked. Also maybe the idle timeout length?
Sent from my SAMSUNG-SGH-T989 using xda app-developers app

I said it was in sleep mode, should I turn that off? I mean if it's on sleep, then I won't be able to get calls or messages since I'll barely have service in my basement or office...

Not sure, that's why I suggested the time out length. I don't need wifi much, but I've had similar issues coming off the subway with data not coming back immediately. Usually switching airplane mode on and off makes it work.

[Q] Does your WiFi go to sleep while screen is off?

Hey,
I've noticed no matter what settings I use for the WiFi sleep policy, it remains on and drains a bucket load of juice.
Any observations?
P.S. my bad, if there's a thread already. couldn't find it

Actually i am super glad. I like to still receive emails, new alerts, sport scores etc when phone is sleep. I would of returned the phone in a heart beat if I didnt have a data connection in sleep mode.

What setting you use.
In wi-fi,there is advance option where you can define sleep policy.

Hello,
You can adjust the WIfi option with *#0011# code on dialpad.
When entering ServiceMode, press the Menu button and select "WIFI".
Check if your WIFI Power Save Mode is turned On or Off.
Hope this help. :silly:

[Q] enable airplane mode turns wifi off in 4.2?

i have 2 gnex phones that both just updated to 4.2, and prior to the update, when i turned on airplane mode, cell data would turn off but wifi would be left on.
after the 4.2 update, one phone continues to work that way, with airplane mode on, cell data is turned off but wifi is left on. the other phone, enabling airplane mode turns off both wifi and cell data.
i know that apps are not able to toggle airplane mode anymore (AutoAP) because of security changes but why would airplane mode work differently on 2 phones running the same 4.2 build?
both phones are running stock android, no root, no flashing.
is there a setting i'm missing? was this something in the update that other people are experiencing?
thanks for the help!

Can't you just toggle wifi back on after?

yes, but it immediately shuts wifi back off.
with airplane mode on, i can go to the wifi settings screen, and hit the toggle, it turns on, scans, finds the local wifi, connects and at the same moment it connects the wifi on/off toggle flips back to off.
just seems weird that it is happening with this phone but mine is working as expected...

Then you must go back to 4.1.2 with 4.2 gapps.

any idea why it would work with one 4.2 phone and not the other?
seems odd i'd have to backport one phone but leave the other at 4.2

This happens on my Nexus 4. Airplane mode constantly disables WiFi, no matter what. And yes the app AutoAP doesn't work either.
I have found this app, Airplane Mode Wi-Fi Tool, funny that it was made for Android versions prior to 2.0.
The actual app doesn't seem to work (to enable/disable airplane mode and WiFi), but within the app lies a nifty feature in the Preferences menu under Extras:
Keep Wi-fi On
Wi-fi on Airplane Mode
Check both of those and you should be able to turn Airplane mode on and then keep WiFi on.
Cheers.

i could check "keep wifi on" but whenever i went back to that settings page, it was unchecked again. like it was refusing to save.
the rest of the settings saved.

im on ARHD 7.0.0 and even in prior versions, when airplane mode was turned on wifi would turn off but it could be turned back on. how come your wifi stays on during the airplane mod transition?

Isn't airplane mode means disable any active radio transmission includes Wi-Fi which is sent and receive data ?
If you just wanna stay off calls why don't you just use automatic redirect incoming calls to voice mail or just simply pull out the sim card?

Airplane mode is supposed to turn wifi off (its a transceiver). However, You can turn it back on while airplane mode is activated and still have the other functions off.

That how airplane mode is supposed to work, thats not a bug, every phone ive had does this

i don't know why, but wifi always has always stayed on when switching to AP mode since i got our Gnex phones in sept. (4.1 i think). wifi even stayed enable when switching to AP mode in my old crappy kin two.
and i think it must be fairly common based upon the instructions in the $30 cell service thread, but i'm no android expert so maybe i'm wrong.

There's a lot of talk about this. Check the [GUIDE] to voip/$30/month plans. But it sounds like google moved it into part of core services or something like that. So none of the autoap type programs work any more. But one member had this suggestion below in that other thread. Gotta buy Tasker, but should be able to get back to working like AutoAP did.
Download Secure Settings. Launch Secure Settings, go over to the Helper tab and install the helper. Then go to Tasker. Go into your task and delete the Airplane Mode radio step and the Airplane mode on step. Then hit the + at the bottom left, go to Plugins, select Secure Settings. Hit edit. Scroll down to "Airplane Mode Radios" and select it, and then select "Cell" from the dropdown. Hit the save button at the bottom left and select the check mark to create the task. Move the task where it needs to be by dragging on the right side up and down. Then create a new task, Plugins, Secure Settings, edit, Airplane mode, on, save button, check mark, move to position. You can figure out the rest. Works perfectly.

Llama works as well, it's free and looks less complicated

Many thanks. Got this working after playing with Secure Settings and Tasker, works great...:good:

keep wifi on in airplane mode
I guess I have figured out how to do it with Tasker or Secure Settings.
Both have two actions like "Airplane Mode" and "Airplane Radios", so the second one doesn't turn off anything, but set, what to control with "Airplane Mode" action. Setting seems to be system wide and permanent (saved after reboot).
Good luck

No data when book cover is closed

hi, i am using an original samsung book cover purchased at amazon (48 euros) and was happy with it. however, i noticed that when closed my data connection is deactivated automatically. i tried to search under the settings but i could not find it. is there any settings we could changed to enable data always while the cover is closed? one more thing, when my screen turns off, the data will also be disabled, how can the settings be changed for this? i could find the settings for this but even if i enable the data when the screen is off, it deactivated it. is it because i'm rooted with CF-auto root? i'm running nf8
thanks

Never heard of this. I checked mine and it works. I have the WiFi only one. Do you have the LTE version?

Do you have power saving mode turned on?
Trying toggling it on and off.

No, i didn't turn on the power saving mode and i also have set the timeout to never under the advance settings for mobile hotspot. This might be a bug for NF8? i have to open the cover again to activate the data.

Mobile Hotspot? You mean WLAN - settings - extended… ?!
