WiFi keeps turning off...

Hi all,
I just got a Droid 2 Global today and I notice if you leave it alone for a while (which is hard to do with a new phone) the WiFi will turn itself off. The first thing I do with new Android phones is turn the WiFi Sleep Policy to "Never". And that is what I did today, but it still appears to be sleeping.
When I wake the phone I notice that the WiFi is off (Both up in the notification bar and the widget is dark) and the 3G is off as well. The only that is showing is bars. In about 5 seconds the WiFi will turn back on and connect.
Now this only happens if I don't play with the phone for a while. Turning the screen off and back on the WiFi will be on like normal.
As this annoys me that it is doing it, it is the 3G is off at this time as well. Which means the phone isn't getting any data during the period that it is off. Which isn't good since I rely on Google Voice for all of my texting, which won't come in unless there is a internet connection.
Any help on this will be great,
Thanks

I did find out what was going wrong last night. In Settings>Battery Manager>Battery Mode it was set to Nighttime saver. That would have been bad because I work 3rd shift and I'm up and using this mainly at night.

Wifi not turning off after screen is off

My rule for wifi is to turn off when screen if off. I notice that my mail is still coming thru when the screen is off.
I'm getting a lot of battery drain. Anyone know what I can do to solve this issue?
What do you guys use for the rule of wifi to reduce battery?

what rom/kernel are you using (you should always mention thse when asking a question like this fyi). revolver just fixed this problem yesterday, try updting your rom/kernel....

I'm using the latest stock rom..I think 3.2?
How do you update the stock rom or solve this issue?

Root and flash a custom rom. Revolver 3.2.1 fixed this issue i think...

I am on stock 3.2 and no problems. Have you checked the battery info. That is the best time to check how much time the TF has been on and how much time wifi has been on.
It's true that wifi doesn't disconnect as soon as screen goes off. It maybe takes some minutes for wifi to actually go off. Also, if I am using any app that uses wifi (like radio streaming), wifi won't turn off.
Anywy, most of the time wifi will go out just a couple of minutes after screen goes off. Check settings, running apps and battery stats.
Regards.

The stock rom is set to time out 10 minutes after the screen is turned off I believe. The revolver rom now has an option in revolver parts to set how long till the wifi is disabled.

There are several apps that keep wireless and/or GPS alive after screen is off. This is due to the way the OS handles apps after you stop using them. Try turning off TF then restart and without running any apps, let is sleep. Then check to see if wireless went off.

same issue
Hey, I'm having a similar issue.
I'm on a B70 running revolver 3.11 and a stock kernel and I've noticed my wifi intermittently toggles the disconnect policy to "never" instead of "when screen is turned off".
I thought it was part of the custom wifi timeout from revolver parts but according to battery usage in settings (and massive battery drain) the wifi isn't actually being switched off when the device isn't in use (tablet idle rarely shows top of the list).
I've tried flashing new roms and kernels but haven't been able to work out the specific cause of the problem or how to fix it. I would have posted in the revolver discussion to find out how the wifi timeout is managed as this might have given a clue but alas I am a noob

Honeycomb is not good at keeping wifi off with the screen when other apps request a connection
Grab "Auto Airplane Mode - by Don" from the market free and it does exactly that, screen off = radios off, screen on = radios on

Well my TF wifi off with screen off work except it work too good.
It work but after it goes to deep sleep it does not want to turn back on ( would need a reboot of TF for it to work again) so I set Wifi sleep policy to never and use Auto Airplane Mode.
Prime 2.1.1 w/ Prime OC kernel

Downloaded this app and it works a treat. I'm a bit anal so I'll keep trying to investigate why the system isn't doing what it should but its nice to have something to save the battery in the meantime.

ICS Wifi stays on while on sleep

Hi guy, my wifi won't turn off when my Xoom is on sleep. I have set the settings of 'keep wifi on during sleep' both to 'NEVER' and 'ONLY WHEN PLUGGED' but nothing happens. Wifi stays on and keeps draining my battery life. I am running rooted with the latest version of nightly 62 and I've been having this issue since 55. I have reinstalled, flashed, factory reset, wiped my Xoom.
Is anyone else having this issue? What should I do?

From my experience, wifi stays on for a little while longer after device sleeps. However, some apps in background may trigger wifi back on again. So I turn off wifi when i go to bed. Actually i notice wifi itself will not drain much battery, 1-2% for 10hr. It's the host apps sucking the juice.
I am not an expert though.

OK i've also checked it out and as you said wifi turns off after some time. My main problem now is that my battery life won't last more than 3-4 hours on wifi.
I have posted my battery stats with use of web browsing and watching pictures on gallery...

What do you mean "no more than 3-4 hours"? In your battery chart, you can get more than that even starting from 75% battery.

What I wanted to say is that I think my battery won't last more than 4 hours with wifi on and some serious usage.. from my stats as I can see I've been using it 5 hours but I only had screen on and browsing the web. I think there will be a huge difference if I am watching a movie or playing a game.. I don't have the time to check it now but I will post my results in some days..
According to my previous battery graph do you see any problem or something less from what your Xoom battery holds? Does this battery drain seems normal to you?

I think you'll find it will stay on for about 15 minutes. There is some setting in a system database (using a sqlite editor) that can be changed to bring this down. I doubt Wifi is what's draining your battery. Are you synching email via activesync or running other stuff in the background?

I am only using my yahoo mail from the EMail app. I don't know if it uses activesync. I have set it to check emails every 30minutes.

wifi not turning off
Edit: I found the wifi sleep option in ICS. Google sure did a great job of hiding it. See attached picture for anyone else having wifi staying on during sleep issues.

So there are three options
Keep WiFi on during sleep
1) Always
2) Only when plugged in
3) Never
What option to set if i want Wifi to turn of after some time of when phone sleeps. Previously i had set the option to 15 minutes but that option is not available in ICS and i m having a hard time understanding how these options work on my sensation.
Can anyone explain what each of these options do ?

My guess:
1) Always: WIFI always on no matter awake or asleep
2) Only when plugged in: WIFI always on only when plugged to power
3) Never: WIFI will be off if asleep (my current setting)

That was it

Thanks, I had not seen the option to turn wifi off during sleep.

Bear in mind that (irritatingly) applications can seemingly change this setting.

For an app to change wifi sleep policy, it needs the WRITE_SETTINGS permission.

[Q] [ICS] Disable wifi when screen goes off ?

Hi everyone
I just flashed Android Revolution ICS Rom and I'm quite happy with that so far ! The only thing I cannot find is how to automatically disable the wifi antenna when the screen goes off...
Any help would be much appreciated

You can try in wifi setting and set wifi sleep policy to "screen off" out you can get Auto Airport Mode by Dan

Well I just took a look. Guess they changed it a round a little
In Settings under the WiFi, click on More and there's an "Airplane Mode" try that.
Or try Auto Airplane Mode (this is what I use and it work great)

Wow... wouldn't have found it by myself
Thanks a lot !

I'm noticing the native setting for disableing wifi when sleeping is working poorly. It takes a while to turn it off and then when it restarts the service does not seminar to be able to obtain the IP address and I have to manually turn wifi off and then on again for it to obtain an address. Very strange because the auto airplane app has no such issues.

I have just found out that:
(under GB) "Advanced > Wifi Sleep Policy > when screen turns off"
is NOT the same as
(under ICS) "Advanced > Keep Wi-fi on during sleep > never (increase data usage)"
It is supposedly to be the same thing but it is not.
As osho741 observed, it takes a very long time to turn off and most of the time it just does not.
I think this is one of ICS bug.

It does turn off fine here after around 10 minutes but it takes at least 30 seconds to activate and connect.

Is there any specific reason youd want to turn off the wifi during sleep? In my experience it doesnt drain enough battery to bother turning it off.
In my case with wifi on and a few apps running that uses wifi all the time, the tablet drains around 15-20% over 12h while sleeping.
That gives at least 2.5 days batterylife if you keep it sleeping... I cant imagine you would have to have it turned on (sleeping) longer than that. In that case you could just shut it down completely when youre not using it

you should give juice defender a try. it revolves around battery optimization, but it isn't a task killer, it just lets you make whatever setting you want concerning turning off services like wifi, bluetooth, etc.. its highly customizable, so you can set it to turn the wifi off entirely while its asleep, or to keep it off, while turning on in whatever time increment you set, long enough.
i have mine set so that the wifi turns off and stays off entirely when its in sleep mode, but if i have a online radio app like pandora or 8tracks running, then they override the sleep settings, and keep the wifi on when the screen is off.or, when i use certain apps that don't need internet to run, like kindle or certain games, the wifi automatically turns off and remains off until i close the apps.
i really like it and i think its made a huge difference in battery. Before if used it, my transformer would drain 15-20% percent overnight with the wifi left on. now, it drains maybe 2-4%.

Turning off wifi during sleep makes a huge difference.
It really saves a lot of battery for me.
And juice defender, while it might help, but on my phone, it causes a lot of wakelocks.
You can check this with bbs.

wifi not reconnecting after sleep

Anyone else having this problem? Sometimes when i wake the device, wifi needs to be power cycled to come back on. I have it set on default which has wifi turned off during sleep. When the problem occurs it says "scanning" until i turn it off and back on.

Try hitting the scanning button at the top. If that doesnt work try connecting to another wifi source then reconnect to yours.

Scanning did not work and there are no other access points listed. Its like wifi is completly off.

Set wifi to stay on while sleeping. Mine is always on, and no noticeable impact on battery life... and is always connected on wakeup.

i have that same issue and i just press the wifi button, i know it shouldnt need to do it but thats just how it is. it happens to me about 50% of the time (after deep sleeps).

I think that it depends on your router. Both my Samsung Galaxy S2 and my Galaxy Note will have wifi issues if I change the policy to turn wifi off when they sleep. If I leave it at the default setting of leaving wifi on while they sleep, then they have wifi available when they wake. My Note has no wakelock issues. My S2 has a ton of wakelocks.
