While on wifi, do I need to turn off Data in order to save battery? I *think* the phone will use the wifi if its available anyway instead of cellular Data but will actually turning off Data while wifi is enabled and connected save battery?
The data is automatically turned off while wi-fi is connected unless you have some rogue app that insists to use cell data connection.

Note, this is only if "wifi sleep policy" is "never".
Otherwise, it'll go to the cell connection when the screen is off.
The only app I know of right now that can force cell data traffic while wifi is connected is the Market when it does its initial compatibility checks. (Downloads still go over wifi.)

Hi guys,
Do you know if AT&T automatically prefers WiFi over 4G? If not, is there a way to set it so that I can save on my 2GB limit imposed by ATT? thanks

Set WiFi sleep policy to "never" - then the only things that will use cell data when you are connected to an access point are market checkins (but not market downloads) and MMS. Maybe not even MMS.
Note that the phone won't automatically connect to open APs that you haven't connected to before.
If you have wifi sleep policy set to "when screen is off", background data will be over the cell connection.

Sorry but I can't find this setting. I'm looking in power saving settings and the only thing i see is turn off wifi when NOT connected with mobile AP. Does mobile access point mean wifi or cell data?
Settings>Wireless and network>Wifi settings hit menu and select Advanced

thanks,
just checked and its set to never.
I think you want to control access of data retrieval via cell network, right?
what I did was set the receiver options to airplane mode and then only enable the WiFi. That keeps the cell net from connecting. Also d/l an app to monitor your usage for piece of mind.

If you do that you don't receive any call or sms, no?

With APN On/Off, it's a free app. I turn off the data and can still do everything else. It even has an option to keep MMS enabled
I rooted my phone yesterday using MyGKernel and installed droidwall.I allowed all apps to use wifi and disallowed all of them from using 3G but android background services still use data.I got background data and autosync disabled.Also I noticed that after rooting my phone,the screen turns on by itself in random times.I'm running Android 2.3.6,please help !
go to settings - wireless and networks/mobile networks/ use packet data, data roaming. both off, to disable data via cell provider.
i dont know about the screen issue, some app waking you unit up?, you dont need droidwall if you disable packet data.

But I need the packet data to be on for a vodafone app called vodafone buzz.Its an app that lets me connect to fb/twitter/msn/yahoo/gtalk for 1 dollar a month and I don't get charged for internet data.But the problem is the android services use data for no reason even with droidwall enabled.Oh and I fixed the screen thing,it was a problem with an app.

yes its a fact of Android you have data on so they connect .
try Better Battery Stats to see if you can pin down further .

Anyone know of a way to turn "Scanning" for wi-fi networks off after you are "Connected" to a wi-fi network thus saving battery? Turning off "Notify me" does not do it.

I think it stops scanning once ur connected and leave the page..if u reopen the WiFi page it scans then stops,at least in mine it does..

From what I've read, this seems to be the way it works. Bottom line it will scan every 4 secs or so while you are on the settings page in case you are trying to connect to a new network, then revert to wifi.supplicant_scan_interval from build.prop when not on the settings page. It's not clear that it has much of a battery impact whatever you set it to. I leave wifi on all the time and whether I am on wifi all day or out and about on lte my battery usage for wifi is negligible.

My wife has a stock G3 and for months we've exceeded our data allocation because her phone will automatically and seemingly randomly switch to mobile data even though WiFi is turned on and she's home. Turning off WiFi and back on again will show that our home WiFi network is saved, but won't connect. Turning on airplane mode and back off again will get the WiFi to reconnect, but that's not something my wife will remember to check and these data overages are getting ridiculous. Is this a known bug, or should we try to get a replacement device?

Maybe check your apps? Some apps ask for permission to turn on and off Wi-Fi to save battery or when your phone percentage goes down to a certain level. Of not that, then get a replacement. This doesn't happen to me

Did she accidentally save any other networks nearby or have you connected to them? I had a low signal WiFi saved at my house. I had to forget the network because it kept trying to switch networks, then dropping completely. When I only had the primary network saved, it suddenly was a strong and stable connection.
I noticed with other devices that they will drop connection when searching for networks and there are too many nearby open networks too.
I want to be able to switch mobile data off, and go to 2G, automatically when I'm on wifi. I tried xposed's Smart Network, but that didn't work on MIUI. Any suggestions?
Well, I don't know if I understand correctly your question, but Android automatically turns cellular data off when you're connected to Wi-Fi.

I think it doesn't use data, but it's still on.
In and case, I want to go to switch to 2G automatically when I'm on wifi, and back to 4G when there's no wifi connected.
