Hi all, Have N7 FHD with LTE.
I do have a sim card in it, but it is a prepaid LTE sim, as such, Mon - Fri, at the office and at home, I will use WiFi.
Is there a way for me to turn off the Cellular radio, but keep wifi working? I've already turned mobile data off, but it still keeps the radio on to keep connected to the cell network, despite using WiFi as the connection. I just want to maximize my batt life on standby, without having to resort to Airplane mode.
THanks!
Put in airplane mode then turn WiFi on

Airplane mode is the best choice. Else unplug the SIM.

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.
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 just want to save battery. Can my phone switch to 2g if I turn on Wifi?
Any mod or app?
Sent from my Galaxy Nexus
that question hurts my head.
wifi is wifi...it will connect to a wifi network if an open one is around. this does save battery over 3g.
however, this will have no effect on cellular data.
you may be able to go into settings>more>mobile networks>network mode and toggle through some of those options...one of them will probably witch to 2g mode.
FYI, those instructions are for the CDMA/LTE Gnexus....so your results may differ. but that is where i can toggle from LTE to 3g mode....assuming you would be able to toggle from 3g to 2g mode.
Your mobile network gets disconnected when you connect to Wi-Fi anyways. So who cares?
Thanks!

The app tasker can do all kinds of things like this.

Edit: also my phone gets better signal for phone calls while on 2g only inside of my house.

But tasker is damn expensive What about battery life? Does it consume much? I bet it does because app must monitor everything what is happening in th phone.

I have the Note 8 GT-N5100 which is the 3G version that can make calls. It was the only available version in the market here and I do not use it for its phone functions. I see it eats up 3-4% of the battery power, even without a SIM card in place. How would I turn that off, but still will be able to turn it back on when I need it for calls? Putting it to plane mode shouldn't be the solution as I like it to connect to wifi immediately.

Put it in flight mode and then turn just Wi-Fi on.

I also have the same situation.
I just put the device into flight mode and enable the other connectivity options when required like wifi or bluetooth.
It works very well

Fortunately, flight mode and "wifi on" at the same time is possible with the Note 8....
I use my Note 8 3G without GSM enabled all the time.
Wifi is still on and syncing / exchange push mail works like a charm.
Using the pull down menu to enable and disable connectivity options is convenient enough for me.
Otherwise use something like Tasker to automate 3G availability.

When I was at home I'd get a good lte signal.
I've been traveling the last week and I've been on 3g the whole time. I've been in chicago the last two days and still on 3g.
I've tried restarting, updating profile/prl, switching on and off airplane mode.
This note 4 is running stock rom, I've only rooted it and done the sql hack to enable the WiFi hotspot (which I haven't bothered to use since it's 3g).

Any ideas why 4g/lte isn't working or how to fix it?
Edit: checked the network settings and for reason only cdma was on. Switched out to both and I'm good now. Mod can delete this post if you want
Lol classic
So how were you getting a good LTE signal at home if your phone was set to CDMA only the whole time?
Sent from my SM-N915P using XDA Free mobile app
I think it switched over to cdma when i was showing someone the ultra power saving mode and when i switched it back to normal mode, i guess it didn't switch lte back on. I didnt notice the lack of LTE when i switched power saving on since I was on wifi at the time.

Lol that makes perfect sense as it has happened to me b4. Sometimes it stays on cdma mode when turning off ultra power saving. Must be a glitch because it mostly reverts to the previous setting when turning it off.
