Hi to all, i noticed something, also when i have wifi activated i see heavy consumes of 3g data
What can be the problem? i disabled the feedback and the update check over 3g but the consumes are still there
In stand by there's no wifi, therefore 3G is going to be used on your syncs. Or maybe it's something related with yahoo again?

Is there a small utility, registry setting or similar that will allow me to have the 3G data connection disconnect automatically when the display is turned off? I usually forget to turn of the 3G data connection after using Opera, YouTube and so on and it seems to consume unnecessary battery that way.
Is there anyone here that knows how this can be accomplished or is it impossible?
Bumped because it's a very good question....are there any rule based radio en/disabler apps out there? NoData is nice, as are the others, but en/disabling on certain actions/programs would be even nicer
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 there a way to automatically disable the DATA Radio when Wifi is enabled?
I use Wifi at work and see no point in leaving my DATA radio enabled at the same time which is raining my battery. I dont mind missing MMS as I can get those later.
I found some apps in the play store that can do this but i didnt know if there was a way to do this using stock android? I hate having to go to 3rd party apps if there is factory method using the stock software.
I'm pretty certain it is disabled when wifi is connected.
Edit: added screenshot.
Yes, cell data is disabled when wifi is connected. It drops down to umts to conserve battery.
It would be nice if it switched down to gsm though, although I'm not sure if these newer radios have improved on umts power consumption relative to gsm. You might be able to achieve this with tasker or similar.
If you want an app that can automatically enable/disable wifi depending on location (based on cell tower as opposed to gps), Wi-Fi Matic works well.
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.
