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

If you enable WiFi the 3g/H/H+, and so forth, icon disappear, but if you got to settings-wireless and network-mobile network settings ->Use packet data is still enabled. So am wondering does the network data go to sleep while WiFi is on? So i won't gain any battery by disabling data while WiFi is on? Or would i gain some battery by doing this?

Data is still on even when the icon isn't displayed. You will save battery disabling it manually because it will disable the data radio.

Okay, thanks for the fast reply =) Another question, with data disabled and wifi on, is there any feature that will be disabled because data is disabled? Like won't i be able to receive MMS for example?

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.)
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 .

I have a Tasker profile set to enable wifi whenever my home access point is within range. The problem is that it doesn't enable wifi, even when the profile activates. When I unlock the phone and open the browser it uses the data connection, and doesn't enable wifi. Has anyone else had this problem with Tasker?
I also run Juice Defender (Ultimate). Could this be causing a problem with Tasker's control of wifi?
Could be, I also had this problem when using J.D. Since I stopped using it had no more probs and battery got better!

Correct me if I'm wrong, but, if you have Tasker turning off Wifi, as in Disabling itself when out of range, than how will it be able to know you are in the vicinity of a hotspot to Enable itself? As in, its off, it can't detect wifi signals, so how can it know you are in the vicinity? You might be better off using a GPS option to enable Wifi.

Tasker will peroidically toggle wifi on to check if you are back in range of your access point. You can adjust the checking period within tasker.
Best to set the time to, say, 15 mins (set as 900 secs in the app).
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.
