Will I save battery to turn off data when I am on wifi? Is there any toggle that will turn on wifi and turn off data at the same time?

Um, you could use Tasker...
But technically Mobile Data is disabled when you have an Active WiFi Connection..
Its still functions for MMS and such though. (I think, maybe it downloads those via the WiFi Connection also, have not looked into it before)
But yeah, Not really going to save any battery, since mobile data should not be used anyways when you have an active wifi connection
When you are on WiFi, the cell towers will never get used for data. You will still be connected to them for receiving phone calls, but that should not be a big battery drain. The phone battery has enough power to keep stay in standby mode for a week. The WiFi data will take many more times the amount of power.

It will save some battery. You want to look into an app named Tasker. You can basically write rules that perform this and many other tasks. There is a bit of a learning curve to the app though.
Data connection is automatically disabled when you are using WiFi. If you are connected through WiFi, you will notice that there is no G or H or anything on the signal bars.

hi,
the data (3g/2g) is taking alot of my battery life..
i'm looking for someting like "setting profiles" that is running as a service and while being connected to wifi its automatically disabling the data (Data enabled)
and returning it to enabled when there is no wifi connection...
i didn't see in setting profiles option to set profile without data....
when you connect to wifi, android OS turns of the 3g data connection already.
Check out Tasker: http://www.appbrain.com/app/tasker/net.dinglisch.android.taskerm
There's a free trial of it for a week...http://tasker.dinglisch.net/download.html
As far as I know, Android turns off data when on wifi automatically without any additional software

Turns off, or just uses the WiFi preferentially? There's a difference, though operationally perhaps irrelevant.
My NS frequently shows BOTH the WiFi connected and the Edge signal indicator while I'm at home. Both green.

it turns it off. the 3g data session is terminated once you connect to wifi, and when you turn off wifi, the 3g data connection is re-established.
Agreed, it turns OFF the the 3g data. Notice that when you get on WiFi, that the wifi icon appears, and the 3g icon DISAPPEARS. This is because it's disabling the 3g since it has access to a wifi connection
this has been the default since as far as i've used Android
If I have just my cell radio enabled, then I enable the WiFi - does the phone disable the data on the cell radio, or leave both enabled?
If both are enabled, then is it bridged or not? In other words, when I have my WiFi on, will I get the speed of my WifI + Cell service?
If the data connection is not bridged, then it seems pretty silly to have WiFi options on location apps, like Latitude, since this means that if you lose the WiFi connection, the phone will not know to switch back to the cell data connection.
No when wifi is enabled the phone has no use for 3g so it disables it until u turn wifi off. Oh and I use an app called quick settings from the market cause u can manually turn off everything with it and makes ur battery last way longer too

I would like to know the differences in battery life 3g vs Wifi. I also would like to know if the focus automatically cuts out 3g to use wifi; as i understand wifi is more efficient and usually faster bandwith rate. How do people have there settings configured wifi and data on, wifi no data, or data and no wifi?
wi-fi uses less battery and faster in general than 3G when actively transmitting data. Wi-fi uses more battery than 3G when your phone is standby and not transmitting much data.
Wi-fi will automatically cut off 3G when it is activated. However, if your phone is not plugged in, wi-fi will automatically be turned off when phone screen turns off.
I have data toggled off, and wifi on, I am revceiving text messages when the screen is turned off. Would that mean wifi hibernates and wakes up when someone is trying to contact the phone or that the wifi is on even when the screen is off?
Text message does not use wi-fi or Cell data. It is the same as voice calls.
You can tell that your wi-fi is off while sleep when you turn the phone on and look at the wi-fi icon.
There is really no reason the manually turn off the cell data unless you don't want to use it at all. Just remember to keep the phone plugged in when you have wi-fi access.
For me its pretty much the opposite. Having wifi on drains my battery very fast, even if I hardly use the phone. My battery is totally dead with very light usage by the end of the day. Turn off wifi and I'm still at 50% by the end of the day with the same usage. It's bad enough that I just don't use it anymore.

That's exactly what I have posted above. Nothing is opposite about what you have experienced. If you don't use data much, wi-fi ends up use more battery than 3G. If you use a lot of data, e.g. browsing internet for hours, 3G uses more battery than wi-fi.

Michael, awesome article so officially wifi uses less than 3g. furthermore, if you use wifi and your screen goes off the wifi rests until your screen is back on using even less battery.
Power (mW) 3G (700) vs. Wifi (650)
Is it my imagination or do apps that use my wifi connectivity seem snappier when the data network mode is deactivated (from menu after long press on power button)? It seems like they are pulling the data faster. I am wondering if they stop to look at 3g/4g before going to wifi when data network mode is activated?
honestly, i always turn off my 3g when I'm close to a wifi connection. saves battery & its way faster
Juice Defender for the win #FTW
Y'know, I've never tried this and think I may. Wonder if it does make a difference since I'd hope WiFi would override it anyhow. I don't see the icon for it on WiFi much of the time anyway, but is that proof? Thanks.
I am curious also? So you are saying if you disable mobile data, your wifi will pull data in faster because it doesn't have to check if 3G is on?
That would be cool, cause I am on wifi almost 90% of the time - although I would probably forget to turn my 3G back on when I got to my wifi zones.

That was just a guess. It could be nothing more than my imagination - but it did seem a bit quicker to start pulling data.
I have never turned my 3g off and have noticed at times it is slow and other times it is really fast. It mostly has to do with the transmissions and receiving of packets from your attennas
The phone automatically disables 3G and 4G data when on wifi.
Is anyone here using Leandroid to turn off wifi, GPS, Bluetooth and drop from 4g to either 2g or 3g connection when the screen is off? I had tried on OOS Andrew on CarbonROM but can't get the data connection to change from 4g.
Anyone had any success with this or could point me to another app that does the same?
There's no point in changing from 4G to 2G, it won't save battery. In fact it will likely make it worse since the radio will be active for much longer during the sync process, especially if there's a fair amount of data to sync. Only thing that would really help is turning off WiFi, GPS, Bluetooth, or mobile data all together.
