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

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.

When I'm at home I use WiFi and the 3G icon is off. As long as I'm actively using the phone this seems to be the case.
I've noticed on more than one occasion that when I unlock the phone after a prolonged "sleep" it is connected to 3G and switches back to WiFi!
Anyone else seen this?
Is there an explanation?
I have noticed this too and I have my WiFi sleep policy set to Never (check yours perhaps).
A little bug I would say.
Unless you've adjusted the wifi sleep policy, this is normal behaviour.
By default, when the screen switches off, so does wifi.

HA! Another Advanced settings menu under the WiFi settings menu.
My WiFi sleep policy was "When Screen Turns Off". Sneaky.
Changed it to "Never". Let's see what happens.
With SYNC ALWAYS for e-mail/facebook/twitter, which uses more power/drains battery faster: WiFi or 3G?
I'm pretty sure Wifi is nicer on the battery than 3G, at least from what I've read and my own experience.
It depends on your signal from both (which equals required trasmitting power), I'd say.
WiFi power is pretty much constant, 3G/HSDPA can vary and get much higher than WiFi.
I have read that when you are connected to WiFi, it is always slightly better for power (I am sure range and signal strength do come into play though).
When you are not connected to WiFi, then the wireless uses loads of power trying to hunt a network down.
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.

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
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)
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.
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.
