I have a evo view 4g and its not in service. Ide like to save battery by completely disabling the 3g/4g support. Is there a cwm package or something in the system I could remove to disable the radio?
If you just un-check mobile data it turns the 3g/4g radio off..

I run my View in airplane mode and then just manually turn the WiFi on and off.
No it still searches for signal thats what the bars are on the status bar. So in essence its still using power to search for a cell signal to connect to. Doing that stops data connection but it doesnt turn the radio off. You can do that on a phone but going through dial info thing. On our tablet you cant just do that it has no dialer.

It helps if you use the Quote function so we know to whom you are replying.
Look, in airplane mode my View does not search for signals. Airplane mode has to stop the radio, that is what it is for. I'll take a look at my View tonight, but I don't think I have any bars on my status bar, since I keep it in airplane mode all the time.
EDIT: If the radio is indeed still on, HTC has a serious problem in integrating hardware and Android.
Ok, I'm on my view now and there is no signal strength icon. Turn on airplane mode to shut down the modem.

I have a Vibrant with no data plan (I'm in Wi-Fi 99+% of the time). How can I turn off both the 2G and 3G radios, both to save battery and to make sure I'm not accidentally charged for using data?
I searched around and there are a ton of apps and widgets to toggle between 2G and 3G or disable 3G (Smoda, APNDroid, etc.), but I haven't found a way to turn both radios off. I also poked around in Service Mode, and the only options I found were to toggle between 2G/3G, not turn the radios off. Any ideas?
Not sure you can. Airplane mode will kill the WiFi too. But the best bet would be to stay on 2G and disable data roaming.

Trigger Airplane mode, slide down notification area, turn wifi back on. Bingo. I do this at School in areas where I get no reception at all but has wifi access.

Another option would be *#*# info#*#* then go phone information ..scroll down and hit "turn off radio" and your good to go. Or you can hit menu and press "disable data"

APNdroid shuts them off Ive used when i used my vibrant as prepaid to save battery. After you disable you have to reboot
Thanks for the help, everyone! Airplane mode + wifi is perfect.
(About APNDroid: as far as I could tell, it just changes your APN entries to invalid addresses; it doesn't actually turn off the radio. So you can't use 3G, but I was afraid it would still use the radio while searching for the invalid networks. But I don't have a great understanding of HSPDA, so I could certainly be wrong on that.)
just a heads up, airplane mode also disables calling/texting
Yes the radio would still be searching for networks if you disable the apn
If you get the Juice Defender app, it has a "Toggle Mobile Data" widget. It's a nice 1x1 widget that turns off the mobile data radios (but not Wifi). This is the best solution I've found.

Since I am dropping my sprint service I want to disable the 4g and 3g radios but leave the wifi enabled. The best way I have found so far is to put it into airplane mode and then enable wifi. Is there a better or more permanent method to do this?

LTE On/Off from the Android Market provides a shortcut to the radio list; there's a "turn off radio" button at the bottom.
It was intended for use on the Thunderbolt, but works great on any device.
Keep in mind that this does not persist through restart.
Thanks for the info.
I dont have my view yet but I read this on the hero forum
"In the dialer put in *#*#4636#*#* then go into Phone Information then scroll down and select turn off radio."
But instead of the dialer you enter it in the calculator (from what I hear from viperboy). He tested it and it does disable the radio(not sure if just wimax or 3g as well) and I'm not sure if it sticks after a reboot or not or if it leaves Wifi turned on (something I find annoying about airplane mode, having to enable wifi every time I boot)
FYI: if you enter the passcode as !+!+4636+!+! in the calculator, you can indeed turn off the radio. Unfortunately, it comes back on after you reboot. The better option, then, is to keep it in airplane mode and enable the wifi when you need it.
I use the lte program with a shortcut, bt dont work in airplane mode btw.
3 out of 4 times my phone fails to disconnect the mobile data network when I connect to WiFi. This is draining my battery unnecessarily.
What could be causing this unless I can fix it so it is automatic I will have to stop using wifi so it doesn't waste power keeping both connections going.
I am running a 2.3.6 rom.
Do you toggle the connections or just enable/disable WiFi? When you enable WiFi and connects, does the 3G icon (the two arrows) appear next to the WiFi icon?
my phone does both I have a program that shuts it completely off when I go to work then back on when i get home based on time.the rest of the time it is on even if I go away which then it just disconnects but wifi is still on.
I have not paid enough attention to when it happens but when it does I have both the wifi icon and the data arrows at the same time.

I think you just answered your own question
What program are you using? Might a suggest a change for Juice Defender for example? or many others that do the same thing...
When I am at home on wifi, and even with "mobile data" turned off, I still have a 4G LTE icon in my status bar. Does this mean the cellular data radios are still on and drawing power? If so, how can I truly turn off the cellular data radios (but keep the cell radio for voice on)?
Note: I did see the *#*#4636#*#* trick, but I'm hoping for something much simpler, ideally a toggle widget. My phone is rooted but I do not want a custom ROM.
(Apologies if this question has already been answered, but I wasn't able to find it through searching.)
It should do that automatically, mine does.

I have a new gear s on Verizon and have found the battery life very variable for lack of a better description. It appears the Verizon version does not display the same info in the moments bar as the Samsung manual shows or as I have seen on other carriers versions. I ask because my battery life in auto connect verses always off is a major difference even when connected to the phone via Bluetooth. It almost appears the 3G/4G is always on in the auto setting. worse case connected to the phone "note 4" via Bluetooth and network in auto I was getting 7 hours from 100% to 15% battery. If I turn the network off in the same situation I got over 40 hours and still had 25% battery left. Does anyone know if the Verizon version actually turns the network on/off in auto mode? Since they don't display this information in the moments bar you don't know if you are on, off or remotely connected. The 3G by the signal strength bar graph is always on whether you are on or in auto mode. Thanks for any help you might have.
I have the Verizon version also. When I'm by my phone Bluetooth automatically turns on and 3g turns off and vice versa. I had problems with it not automatically switching 3g off so I ran clean master from the Samsung store(made for Samsung phones) and ever since then it always works with auto connect

Thank you for your response. I tried your suggestion but can see no immediate difference. If I may ask how do you know 3G/4G is turning on and off? On my watch the Bluetooth symbol in the moments bar will change either having the additional white triangles on each side when connected. The 3G/4G and signal strength bar graph is always there in the on or the auto. Only off will make them disappear. Thanks.

The 3g disappears and turns off the cell radio then connects to my phone Bluetooth. Double check your settings under connections, then mobile networks, make sure gear network is set to auto switch

Thank you once again for the information. I pretty sure mine is not working as it should. I have the 3G and signal strength bar graph if the mobile network is on or in auto phone connected Bluetooth and inches away. You need something to know if its on or off as you stated 3G there or off. The weird thing is with the network in auto and Bluetooth connected I put the phone in airplane mode then tried making a call from the watch. It would not do it. The 3G was there telling me the network is on but not making phone calls. I tried sending a text to the watch phone number with the network off and as expected it didn't come through even connected to the phone via Bluetooth. If the network is in auto and connected to phone via Bluetooth the text to watch phone number will come through. I'm guessing to get calls or texts to the watch phone number the network must be on. I'm curious if yours behaves as mine does. I have had the note 4 since January and its getting pretty cluttered with stuff plus add the lollypop update to the mix. I have tried a hard rest on the watch and think I'm going to do the same to the phone to clean house and try from scratch. Thanks again.
