Does the Wifi Calling app save more battery? I've noticed the network signal turns off when I enable Wifi Calling

Yes, saves LOTS of battery. Big difference when wifi calling is on.

Expanding on OP:
Does WiFi automatically supersede data as well? And if so, is there battery saving in that case?

When you turn on WiFi, all data goes through WiFi assuming that there is a good signal on it (aka if WiFi is so bad there is no data throughput, the phone will turn mobile data back on). The phone will always choose WiFi and turn off mobile data. Some/most people say that this saves battery because the phone isn't always searching for mobile data. I'd say that this is more true if you're in a situation where there is poor/low 3G reception but good WiFi reception. I almost never use WiFi because I get full bars and good 3G speed at home. I see no reason to use WiFi in this situation as my phone isn't searching for better networks.
As far as WiFi Calling goes, in the settings of the app you can choose to have the phone "Prefer WiFi"/"Prefer Cellular"/"WiFi Only". Same thing here. If I use WiFi calling, I choose "Prefer WiFi" because if for some reason my WiFi goes down while I'm not using the phone I want the mobile network to come on so I can receive calls without having to toggle back. A situation I could see where "WiFi Only" would be applicable is if you're traveling and want to use WiFi for calls if you have a data-only prepay SIM, or if you're in an area with only Roaming coverage and you would want to just use WiFi to make calls.
Is it possible to just turn off the 2g radio and have wifi on since I'm in the library? Thanks in advance buddies.

When your on wifi all data automatically uses wifi. The 3g radio stays on so you can get phone calls

Just turn off Mobile Network in settings-wireless and networks. This disables 3g and 2g.
I do turn off mobile networks but isn't texts still 2g?

I think text work off your cell network not 3g or 2g

Ok so it would be calling through wifi, texting through 1g?

No no Calling uses the Radios. And texting uses the radio not the 1X (2g) or the 3g (3G)
MMS uses 3g or 2g. soooo and wifi is data only not calling unless you use a voIP
Ok thanks for the clarity. But as i was saying, if I am in an area with wifi only no cell coverage;can I just turn off the radio then?

If there's no cell coverage whatsoever, turn on airplane mode and then turn on wifi. If you have wifi turned on then turn on airplane mode, wifi will automatically be disabled. You can turn it back on, though. Airplane mode will disable all radios - this means no calls or texts. Alternatively, you can just turn off mobile data - this will allow you to receive calls and text messages. You should be able to receive MMS (texts with media attached) on wifi as long as you have cell coverage.
I use a toggle widget to do these actions from my homescreen... Widgetsoid is my personal favorite. It has the only mobile data toggle that I've actually seen work without messing with my APN from a widget, just choose "root toggle" as the method in preferences. From within an app I use my notification toggles as I generally have my status bar hidden on the home and lock screens.

What is the difference between LTE and Mobile Data?
Lte is a type of mobile data hspa+ is another type
Mobile data is data streaming over your carriers network. It what you use to browse the internet, check emails pretty much everything on your phone except calls and texts.
LTE is the speed of your mobile data connection, currently the fastest. There are different mobile data speeds, 2g/edge, 3g, 4g/lte.
Hopes this clears this up foe you.
Edit--> beaten to the punch lol
Thank you for the explanations. While I am at home or work I was trying to decide what items to turn off. I can turn off the GPS, LTE, & Mobile Data and use just use wi-fi.
I believe mobile data already turns off/disconnects when you are connected to wifi. If you go check your "about" screen while on wifi, it will show the mobile network at disconnected.

This ^^^^^
The difference is when your Wi-Fi signal depreciates (for whatever reason), if you still have Mobile Data enabled, your carrier's data will pick up right where Wi-Fi left off.

Yep you are correct. I turned on/off the wi-fi and the mobile network state turned on/off accordingly. Does turning off mobile data help extend the battery?

Thanks for the tip!
The reason I ask is because I am setting up some NFC tags and I wanted to know what services are OK to turn off.

Yes it does. WiFi uses less battery. Mobile data is right there with display for the two biggest battery consumers.

Good to know. Thanks again.
I'm looking for a automated way to change "network mode" to GSM when connected to wifi. My issue is at work I don't very good LTE/3G service, but great 2G reception for phone calls/SMS and since I'm on my work wi-fi I don't care about having LTE data. I looked briefly into tasker, but looks to be a bit of a challenge due to the pop up when changing back and forth.
Llama is the app you need. Like tasker but way easier set up
You can trigger your event by GPS location or by wifi network.
Set it up so when you connect to a WiFi network it disables your data connection. When you disconnect your Wi-Fi network it turns on your data connection.
Works great and it's free
