Is it possible to make it automatically switch to 2g when mobile data is off so i can save battery and get better reception? Maybe some tasker profile?

I have the Wifi enabled on my Droid Charge so when I'm home it will use the Wifi. But when using the Wifi the 'mobile data' icon is still highlighted in the pull down tasks..
now is it trying to use BOTH the wifi AND the mobile data at the same time? I want to use ONLY wifi at home to help conserve battery usage.
then when I leave my house will it automatically turn wifi OFF and use only mobile data?
trying to keep the battery usuage as efficient as possible.
In theory thats how it's supposed to work.
hahahha in theory.. but does it actually do it?
and another thing.. in the Mobile Networks Settings.. under 'System Selection'.. you can choose either LTE Automatic or CDMA Mode... being I am ONLY in a 3g area and do NOT have 4g LTE in my area yet.. should I choose the setting for 'CDMA Mode' Will that save the battery? or does the phone try to switch from 4g to 3g...
Yes, that is how it works. If wifi is on, the phone will use wifi by default, regardless of what it is connected to for mobile data (4g, 3g, 1x). Check out http://myresolver.info from your browser to see your ip and dns server you're using.
Ok I've got a few questions about the different network types and battery usage.
As far as I know there are 4 different possible scenarios:
3G mode active
3G mode active and connected to mobile data (3G/H showing in notification bar)
2G mode active
2G mode active and connected to mobile data (E or G showing in notification bar)
Currently I have settings default with "Use only 2G networks" unchecked, and "data enabled" unchecked. I have tasker made to automatically turn mobile data on whenever I open any app that may require it, and then turn it off after the app closes, or I can switch it on from the status bar power control.
This is because I assumed having it constantly activated would consume more power. Is this true? does it consume more power having data enabled even when no traffic is going through? If this wasn't the case, I might as well leave it enabled. However with my current system I could still be saving power because if I leave data on, traffic WOULD periodically be used for automatic sync and apps randomly using network and stuff.
The other thing I was wondering about is if there was any major difference in power consumption between 2G and 3G network modes with no mobile data connected. if 2G uses much less power, I could have it set on 2G by default then use tasker to switch to 3G and activate mobile data when opening any internet requiring app. Are there any other advantages of having 3G active over 2G other than mobile data transfer speeds?
Thanks for any help!
Imho your settings are good. Mobile network is one of the battery killlers, so not using (or better using it when you really it), is very good. You are right, 3g has a higher speed on mobile network. Whereas the 2g-network has a much better network coverage. And the permament switch between 2g and 3g drains the battery very fast, too (happens e.g. when you travel).
To sum it up: Use 2g and mobile network off. If you need to use mobile network, turn 3g and mobile network on. Are you done, turn them off again and switch back to 2g.
When you say mobile network, do you mean when an active data connection is enabled?
Because just by the name 'Mobile network", you can be connected to a mobile network for calling and texting etc. without being connected to mobile internet/data.
Is there a difference in call quality between 3G and 2G networks?
Also when toggling between forced 2G only and 3G there seems to be an inactivity period where the reception icon at the top shows like 'disconnected' like it cuts all network communications, then shortly connects again to the specified network type. This delay might be annoying when trying to get internet fast on apps that need it... might not be worth the power saving, if it is only minimal power saving

for the best battery duration, use GSM ONLY!
Hi,
My phone is not activate so it always on the air plane mode to save the battery. I use textme to send and receive text message from the wifi and nettalk to make free call. If a leave the wifi always on to be able to receive sms and disable it when wifi is not available, would be equivalent on the battery life that receive all the time the mobile network?
Thank in advence and sorry for my bad english..
Yes wifi consumes more battery than mobile networks for calling and messaging as that uses the 2G networks which are very light on the battery.
I was wondering should I disable the wifi calling feature(from the Setting>Application menu) if i'm in an area with good reception even when I use wifi often? Would it save more battery keeping it on or turning it off?
Dear friends, some time when I have low 4g signal, I can not receiver calls.
I need some app for setting auto switch from 4G to GSM band, when the 4G is low.
Same problem, I have with wifi. I need some app for setting auto switch from wifi to Data mobile connection, when wifi signal is low.
Someone know any app that I can try for resolve this problems??
Thanks
The firmware has this feature itself.
i.e. it can switch to another network automatically if the current network signal becomes weak.
You should select the network mode as Auto Network Mode for it to function.

Yes, but when the signal is low, the phone don't switch network, because phone see the signal there is, low signal, but there is! But really, when signal is so low, I don't receive calls, my phone number is not available!
I need an app, for setting the minimal signal level, that the phone must change network
