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.

Another potential problem, not a huge problem, but...

Sometimes when my phone comes out of sleep mode, the wi-fi doesn't pick up at all, so I have to disable and then re-enable it.
I tried reinstalling the radio button and still nothing.
I have Battery Defender and GSAM Battery installed and thought maybe it had something to do with the settings there to save power, but there doesn't seem to be anything there that would affect the wi-fi.
Anyone with any thoughts?
Thank you

Battery defender might be putting your WiFi to sleep to save battery when your device goes to sleep.
Also check to make sure WiFi isn't set to standby on default.
Go into settings select WiFi tap menu button press advanced and make sure keep WiFi on during sleep is set to always or a similar setting

Battery Tips

Hello all. I just decided to retire my Vibrant yesterday and got an S3. I haven't changed much on it. I'll run it stock for quite a while. I am using a custom launcher, etc.
My battery life is horrible though! It's not even noon and I'm already down to 35%. I've made sure S Voice is not set to wake up when I talk to it. My weather was set to update every 15 minutes by default, but I've changed it to every hour. I charged it in the van on the way to take kiddos to school, and it was at 80ish percent. So that's quite a drop in not a long time. Granted, it's new, so I'm playing with it.
What tips can you give me to get the best battery life I can out of it? Besides custom ROMs. I'm not even rooted. Yet.

Well how long has your screen been on? That will be the determining factor in your battery life. Like you said, it is new and you are playing with it so I am willing to bet that probably has something to do with it.
Otherwise, turn data off when you aren't using it and keep the screen brightness as low as possible.

Here's what I do with a freshly flashed rom. I pretty much drill down through every setting turning off what I dont need.
WiFi - turn off network notification.
More Settings - Everything off
Sound - turn off everything below "System"
Display - Auto brightness off. Timeout 1min. Smart Stay off. Touch key always on or off. Auto Adj Screen Tone off. Battery% on.
Power Saving - Off.
Accounts and Sync - Off
Location Svcs - Off
Language and Input - Voice Cmd off. Voice Recognizer (all off for google and Samsung). Voice Search all off. TTS driving mode off.
Backup and Reset - can't remember what its listed under but below carrier data press to open and uncheck collect data (this is carrier iq, so I removed it asap once rooted)
Accessory - all off
Developer Options - set animation scales to 0.5x.
Hope that helps. I keep a lot off and only turn stuff on when I need it. There's some pretty cool features but for me it doesn't hurt my experiance with the phone to not use a lot of them.

Ah. My screen was set to stay on for 10 minutes. That, I would imagine, was a large part of my problem. At least according to my battery stats. Why do they set that as default??
My screen brightness is now set to low. What is this with the data? Doesn't that mean I would not receive email, google talk messages, etc?

I just did almost all of these. With the WiFi detection off, will I need to manually find my home network each time I get back home?
Also, if I turn Voice Command off, I won't be able to push the button and say "Listen to blah blah blah" or "Navigate to ....." correct?

I am on CM10 so I am not sure where it is for stock Touchwiz, but I would assume you could go to settings > display > screen timeout and change it there.
Yes, turning off data would mean no push email or Google Talk messages. You could download an app that turns off your data when you turn the screen off, then on when you turn the screen on and your emails and messages would come through then.

I should have also mentioned I turn off wifi and data when I don't need it to, which is rare but it happens at times!
By turning off the wifi notification, the only change is it won't give you a notification in status bar that there's an open network nearby that you could connect to. Itll still auto connect to any network you've already got configured.
For voice cmd, it won't let svoice open apps for you. But for example in navigation you can still hit the mic button on keyboard and speak your destination.

Can you upload a Screenshot of your battery screen... It will make it a lot easier to look at

On the Wifi issue. What I do with regards to wifi, is if I know that I am not going to be near an open connection, I turn it off. When I am at work, there is no wifi nearby that I can connect to. So I use Mobile Data instead. Why you ask? It is because when you have your wifi on, in the back ground it is always scanning for a signal. Turn that off and no scan, then no drain for something that you are not using at moment.
I know that this is a bit deeper than you wanted to go, but in the Build.Prop you can put a setting [wifi.supplicant_scan_interval=] and you can set that out. The time in there is the time duration on scanning intervals based on seconds. So the setting wifi.supplicant_scan_interval=180 means that it scans for wifi and doesn't find one, then counts off 180seconds and scans again.<--This is what I have mine set too, btw.

Disable the wifi when your not using it.

Wireless Shuts off While Sleep - Causes Issue with Tasker

I have a tasker setting that says when connected to wirelsss ssid @ work is disabled volumes.
However every now and then when in sleep mode I will here it turn volume back on as it disconnects from wireless in sleep mode. When I turn screen on it connects backup and puts vibrate back on.
I looked in the network settings for wireless and it is set to Always be on. So I am not sure what else could be the issue. Anyone have any ideas?

I think I may have found the fix.
http://forum.xda-developers.com/showthread.php?t=2077758&highlight=wifi+sleep
I'll let everyone know.
Okay if you are having WiFi issues and it disconnect every 3-4 min here is the fix
Go to phone
On the keypad dial *#0011#
Automatically should go onto a screen
Press menu
Go WiFi
There should be a button there saying WiFi saving and it should be ON turn it OFF
And then reboot
Done
Make sure you leave a thanks if I helped
And I would love to know if this helped

That did not fix it. I heard phone beep that it was coming out of vibrate mode.
So I turned screen on and it went back to vibrate mode. Like the wireless went to sleep again but I didn't catch it as activating on the screen this time. It may have im just not sure.

Settings> wifi> menu button> advanced> keep wifi on during sleep

DSBS and battery monitor widget issues

1) Well for one, I'm on the newest stock rooted, I have greenify, DS Battery Saver so my 3G/WiFi turn off and sleep during screen-off....but sometimes when I turn things on.....everything works for fine like 5 minutes, but then randomly my wifi will NOT connect to my house's wifi network and itll use 3G....which is a huge battery killer....WHYYYYY
2) for battery monitor widget, the widget is NOT updating itself....when u go into the app, the mAh is not updating, it just says +0mah or whatever. there is no update, no nothing. i have no idea whats going on. ive already re-installed and it still happens like this. i love this app but now it doesnt work

Re: Retarded Issues
Did you disable the notification? -_- the phone will likely kill the app if you disable it as it had no exactly way to stay active. You need to set the notification to transparent or hide
It's worth a shot

I don't know how to "ungreenify" something....if I press the "play" button, it'll just start up the application and put it into "pending"
As for the Wifi name on my network, it's something like "FJKD33" its nothing too hardcore, but why would I change it?
