I'm getting a second hand Streak 5". I don't have AT&T, but I recall hearing that dell had also made a Wifi only model. My question is: can I load a Wifi only rom (are there even any?) on it and disable the phone/3G?
There are no wifi only streak 5's only streak 7's have a wifi inly model
try dialing *#4636#*#* (*#*#INFO#*#*) then press call.
try phone information, I beleive there is a button to turn radio off, which should completly disable 3G radio.
Not sure if this will stick after reboot, but I think it should.
settings also gives you the option to turn off data, etc. and if there's no SIM card in it, I dont imagine it will use any radio.
I use APNDroid which seems to disable radio pertty successfully, only allowing wifi connections.
I use my Streak 5 in wifi only mode.
I started off just not having a SIM in it, but I found that cell standby was still eating loads of battery - as much as the phone idle was, due to the fact that they are still able to make emergency calls even without a sim.
The really simple solution is that I installed Widgetsoid and added a widget with toggles for Airplane mode and for Wifi on it. I assume any widget app that allows these toggles would work. I then turn Airplane mode on, which kills the cellular radio, both 2g and 3g, and turn on wifi when I need it - which overrides the airplane disable.
I've even found that JuiceDefender can auto-toggle wifi while in airplane mode based on running apps, though only after rebooting while in airplane mode - before the reboot, it quite sensibly saw airplane mode and left the radios all off.
Thanks for the tips.
Got it up and running nice, again thanks for the tips.
And just to clarify, even if I throw a custom rom (probably StreakDroid) I can't pull phone/3g functionality? Could I pull some apks from the StreakDroid zip to get make it wifi only, or would I need a custom kernel?
Got the galaxy s2 running XWKE7
Under wifi settings>advanced>Wifi sleep policy. selecting turn off wifi when screen is off setting does not seem to take effect.
Tested by pinging it and continues to ping even 5-10 mins after screen is turned off.
anybody else having the same issue ?
Have the same issue, want my wifi to turn off when the screen turns off but wifi stays connected.
Only thing I can think of is that i restored my access point with titanium.
Can this cause any problem and if it can, can I delete the restored settings?
My sleep policy works fine when turning screen off. When i turn on the screen, the wi-fi icon appears after a few seconds. Also the battery usage shows that wi-fi is off when screen is off and phone inactive. Might be related to one of your apps that conflicts with the wi-fi policy. Happened to me when using an app that had options to turn on/off wi-fi scanning.

Weird, will have to check this up.
But as far as I know I don't have any other app that manages wifi.
As you can see in my screenshot, wifi is on at all time even when sleep policy is set to sleep when screen off.
Currently I'm not connected to any wifi since I don´t have any in range at work but it looks exactly the same when I´m connected to my home network.

Hi, I have the opposite problem, I don't want my WF turns off when is sleeping. I remember that a program ask me to turn WiFi in energy save mode but I cannot remember which app and I have no clue how to go back...
Any help?
Tks a lot!

Have you tried setting the sleep policy to 'never'?
Has anyone found a solution to this problem? I did a factory reset (XXKI4) and it was still the same. Screen off, policy set to turn off when screen is off but I can still ping the phone after a few minutes.....?!?
EDIT: I remembered ;-) Had the same thing on my original Galaxy over a year ago.
Needed to edit a database:

Cant save sleep settings.....
I have a slightly stranger problem that's just started. I'm aware of the situation where wifi takes 15 mins to turn off after screen turns off was never bothered with that aspect.
However, since today I found wifi was staying on continuously - checked in settings & wifi sleep policy had reverted to 'never' - I always had it set to 'sleep when screen turns off'.
The problem now is that I change it to sleep when screen turns off' and 'save' this setting but it's not saving - when wifi goes off & then back on again or if I reboot phone, it reverts to 'never'.
Any ideas folks?
Back-up data and factory reset .
jje
Would like to know this too.
Wouldn't like to back up and reset everytime this happens.
Also couldn't find the files in /dbdata folder as indicated by the Galaxy S thread pointed to.
Is there any other solution?
someone says using static IP will solved this issue but It didn't...
Any news on that?

Me too! Any word on that?
Had the same problem, where the battery no longer lasted the whole day.
When I checked under "Settings/ Battery" and clicked on the graph I could see that whilst the phone was sleeping, WiFi was not.
I have done a few "factory resets." All seemed okay to start off with and then after a while I would notice the same problem.
This last time I found that "Google Now" is the culprit.
Just click on the blue Google Icon, under Applications, then bring up the menu, click on "Privacy and Accounts" then "Google Location Settings", then "Location Access" and make sure "Use wireless networks" is not checked. (also available from "Settings/ Location services")
That fixed it for me!!

Mine is not checked and its still keep 'on' for almost hour...
as far as I know its better to be on wifi instead of data, eat less battery... but anyway I guess its have its own wakelocks...
Please explain me, I just dont understand the settings. What's the difference between 3 options: always, only when plugged in, never? I see that regardless of either option WIFI stays on during sleep. It is clearly seen from statistics. So what's the use of it?
Come on people, I can't believe nobody cares. Did I ask something stupid?

well perhaps no one have seen your post.
anyway, i just saw that feature a while ago, and i think what it means is:
when your phone screen turns off (your phone is asleep because you're not using it), wifi connection gets disconnected -- to conserve battery.
the options are:
always (default) - will keep wifi connection turned on, no matter what
only wen plugged in - well, wifi connection will keep on ONLY when the device is plugged in.
never (increases data usage) - as soon as the device sleeps, it will disconnect from wifi, and possibly conneted to data network, hence the warning.

1. Always on even if screen is off (DS WiFi ON)
2. Only when charging WiFi is still on (DS WiFi ON while connected to USB or AC charger and DS WiFi OFF when disconnected from external power source)
3. Never online while in deep sleep - disconnecting WiFi in Deep Sleep (DS WiFi OFF)

Dear friends. Thank you for your replies but I suspect you didn't get the point. Again, regardless of one of these three settings WiFi is still ON during sleep. Try to set it to "never" (given that global WiFi switch is on of course, thus it should go to sleep along with device), disable your mobile data and run Skype for example. After your phone has fallen asleep you still online in Skype and available to receive calls. You're still on WIFI! It doesn't switch off when phone sleeps!
I know this is an old thread but did you manage to figure this out? This has recently been bugging me too. Thanks!
If wifi doesn't disconnect when it's set to "never", maybe your phone doesn't go to deep sleep properly.
It'd be good if we could read somewhere what this "deep sleep" really is..

I agree! phone may not go in deep sleep even after switching off screen.
And also also this question is really not stupid, but I say google is stupid, that he assume we have a data plan active always. I have wifi at home and office, so am not activating data plan. So I was having the same question/confusion about this option!
Keep wifi on during sleep -> never, so how come it increase data usage?? data means not data transferred through wifi but sim card internet!! Ha ha ha..
Google should clarify it that when phone is connected to wifi, it will not use sim card internet, but if wifi is off and mobile data plan is active, android will use sim card internet.
Also I'd like to add that wifi signal itself is not eating much memory, but in most of case, fb/gmail/google+/twitter etc which are always internet crazy (hungry) will not let your phone asleep. and they eat memory. if wifi is off then we can have two option, 3G and 2G phone internet. 3G signals eat more battery, and 2G internet use more battery because of slow speed.
Background activities option came in picture with invention of smart phone, but always misused by google+ and facebook!!!!
I always hate fb android app, it is too slow in 2G and surfing site in Opera mini is way too fast and handy, anyway that was my taste.
Take a look at green power app as this handles 3g/WiFi connectivity very well. Much better than juice defender

Hello guys! I have a really annoying problem with my S3. I use tasker to turn on/off wifi with cell near feature. The problem is that when I get home, the wifi turns on but it won't connects until I unlock the screen. As soon I unlock the screen it connects. This problem I had it with all the roms past 4.0.3 and I really don't want to come back to 4.0.3 only for this issue. I have UltimaROM v8.1.1 Ifrit on it, and I tried with the stock XXELLA kernel, with the Phenomenal kernel and others I can't remember all now.
The setting "Keep Wi-Fi on during sleep" is set to always.
I made the "*#0011#" thing and put the WiFi Power Save Mode to off and don't make any difference. BTW after restart this changes back to ON.
There must be a solution for this. Thank guys for any piece of advice!
So whenever I left wifi area or turn off the wifi soon after the mobile data gets automatically turned off, the icon of it shows not just for specific app.
Even when I turn off the data saver, it doesnt help.
This is very bothersome as I will miss alot of stuff.

Anyone experiencing or heard such problem with Huawei Phone? Need help.
Are you talking about missing notifications?
If you enable Developer Options (settings/system/about phone...then press build number 5 times) then in Developer Options there is an option you can tick to always keep mobile data active. I use it for faster network switching and it doesn't have much of an impact on data use or battery drain.
But if you are talking about missing notifications that might not solve your problem.
You want to remove any apps that need timely notifications from battery optomization in the power settings. Make sure after you choose to manually manage the apps that they are allowed to run at startup and remain running in the background. (All 3 options should be allowed).
If that doesn't solve your problem then you might also need to remove Google Play Services from automatic power management since that service is normally responsible for syncing Android phones.
Huawei has more aggressive power management than most Android phones which provides great battery life but also annoys many people because they can miss important notifications.

No, the entire data just cut off after leaving wifi even thou the mobile data was on prior to leaving the wifi spots or just turning off the wifi. Does that make sense? I have had so many different phone this has never happend to me. I even turn off the data saver mode too.

If I turn that option on in dev mode "always leave the mobile data on" even when the wifi is on (even when wlan is active) does that mean it may sometimes suck up my mobile data while wifi is on, i dont want that.

Ok after tons of digging found the problem. a function i have never seen on previous phones.
basically you go to mobile data setting and go to more and then (wlan/mobile switcher) go in there and thats where the problem is.
I now select switch to mobile data.

I don't see that setting. Does this fix the fact that when you use hotpsot the phone is incapable of any data? I can't use hotspot at the same time as data on the phone itself.
