I've check everything and i can't seem to find the culprit (unlocked AT&T G2 on Tmobile network LTE).
Big problem must google ?

When I first got my g2 I was having battery drain as well turned out for me it was Wi-Fi always scanning under Wi-Fi then settings then advanced Wi-Fi I turned off Wi-Fi always scanning and it's been good since

Is there a way I can toggle between Edge and 3g on the g2 without going into settings? I cant figure it out using tasker and i'm not sure how to use APN droid to do it.
Basically, I want to switch to 2g when I'm at work just to save battery - i dont want mobile data off, i just want it to use the 2g radio instead of 3g.
Ideas? Is this even possible on stock froyo? I know CM can do it.
SwitchPro has a 3G/2G toggle. Available on the Market.
This is in the wrong section.

I used better cut to create a shortcut on the desktop. It works for now, like you I'm waiting for CM to fix most of the stuff that bugs me...
I've been using the "Data On Demand" application on my g2 which turns off your data when your screen is sleeping and then back on when you turn on your screen. It's saved me a lot of battery so far, but as you said you want data to remain on, there should be other applications out there but this is an option.
i wonder since they can turn off data when the screen is off and on when the screen is on if they can do 3g when the screen is on and edge when the screen is off.

Go to the market and install extended controls. Make a widget on the home screen and add the 3g/edge toggle button.

Yea extended controls is the best one. Had switch pro, isn't a great as extended control

Quick, tip, toggling from 3g/edge could burn out the sim card and cause connection problems to the network, or at least that's what the tmob tech said to me. I had trouble with my g2 switch from hspa to edge to cutting off completly, so I called the tmob tech. It turned out I had an older sim card (from the g1, had 3g/2g toggle) and said that that was causing the problem and that eventually it would burn out from switching networks so many times. Don't know if this is true or not but just giving yall a piece of warning. Anyways, I registered a new sim card that came with my g2 and now i get constant hspa and everything is hunky dory
Burning out the sim from switching between 3g and edge makes absolutely no sense to me. At worst, switching from between 3g and edge should be no worse than going in and out of service which, as T-Mobile a customer, happens all the time if you ever go inside. It also seems odd that a supported and encouraged battery saving feature could reduce the practical lifespan of the product. I say chalk this one up to the usual T-Mobile tech BS.
So 2 days ago I updated to 4.0.3 and noticed that when wifi is on that it was impacting me making calls due to where I am I do know get a good signal and data was almost nonexistent.
So I looked on the market and found a free app called "Wifi on call". I downloaded it and just turned on the option while on call: turn on wifi will making a call, and made a call and it went through just fine.
I was hoping to find a wifi calling app that would work with t mobile due to the signal issue but this is helping out for the time being until someone gets a wifi calling app working.

maybe your customer radio frequency is the same of your wifi frequency.
I know this is one app we can try: http://forum.xda-developers.com/showthread.php?t=739530#
But it can't disable switching while do tethering. Can we have this flexible function that we can customize from Settings menu?
I noticed our SGSIII can switch off and on WIFI when the screen on and off. It's good if our SGSIII already have the function what I want and it good enough to now what we do when the screen off, it will not switch to 2G when we do tethering and downloading.

If network idle, it 's will auto down to 3G umts or HPDPA to keep the battery life.
1 hour with auto sync-> 1-1.5%
2g can save battery ?i think not so much with network online.

As I remember correctly AOKP has this feature under their powersaving settings. From what I can tell from my I9000 I always lost mobile data connection entirely when turning screen back on... took 10-60 seconds to get an active 3G data connection again. That kinda really pissed me off cuz it is very likely you need your internet connection when pulling the phone out and turning the screen on ... and in that case having no connection really sucks.
So I never used that option (besides using manual 2G limitation if wanted).

Thanks for the info. My home town just have 2G connection. I think it's better if it directly connected via 2G, rather than the phone continuously searching 3G line.
I noticed that my phone does not switch to any mobile network whenever my wifi strength is too low for Internet connectivity. I have to manually switched to airplane mode then back..
I googled around and found out that it is a common prpblem and Samsung is looking into a fix for it. Is it true?
Is there any app out there that I can use temporarily that switches to the best signal strength? This would help on the battery life of my phone too!
More info: I'm on a Sweden 4.1.2 stock rom (DLL1) with my country's default modem (AJL1). Will it affect the switching? Also I have frozen some samsung default application/service to prolong my usage..

I spent a hour with support on enabling Wi-Fi calling. I set it all up but all I get is a star next to my Wi-Fi signal and no ATT-wifi calling icon in the left top notification area. Any ideas?
At&t is going to call me back Wednesday as I said i would troubleshoot it further. I have reset network settings, resetup Wi-Fi calling and reset my phone

At&t support WiFi calling only if your signal is lower then two bars. If you have plus ( star) sign next to your WiFi that mean your WiFi calling is working. To check this turn airplane mode and connect to WiFi and try to make call. There is no WiFi icon on left side at all.

I will give it a try. I Usually only have one bar. I took my note 5 back because it wouldn't work with my microcell I fought with them for 5 months about it I finally took it back .

Airplane mode disables all radios. That's not possible
Yes it IS possible, after setting airplane mode to ON, go up and turn the WiFi back to ON.

Why don't you try first then tell me what is possible and what not.

I didn't personally have any issues... although it would not activate for the first few hours I had my phone. But I had never used wifi calling before, and why i didn't think of your method of testing it, I don't know. But thanks for the advice.
If I keep the WiFi calling enabled, will it reduce my battery life? By keeping a constant connection or something? I guess I have more than 2 bars for most part of my home.

I can't imagine that it would. Unless you normally turn WiFi off when your not using it. WiFi calling will automatically toggle wifi on and search for a signal. If you just leave wifi on all the time, I can't imagine the wifi calling portion changing you battery life any.

Not just for testing. That method (turn on Airplane Mode, then re-enable WiFi) can be used to force WiFi-calling (instead of using your voice minutes) even if you have a strong connection to your mobile network.
I was having this same issue and by switching to the Sim card that came in the box rather than my old one fixed the problem for me.
