Turn off 3g?

Anyway to turn off 3g in our cdma phones. Might save a lot of battery.

turn off "mobile network" and just use wifi at home?

I've read that the phone constantly searching for 3G and/or using 3G is a big battery drain. Also that unless you require the bandwidth you can do just fine with 2g. There are apps on the market to let you switch 3g off but the ones I found don't work with cdma phones.

Turning mobile network off like said above will turn off 3g...

Doesn't it turn off 2G or edge also. I want data when I don't have wifi. I also thought the phone switched off mobile network when connects wifi automatically.

If you hold the power button and turn off mobile network it turns off 3g. It goes to 1x and you basically receive text and phone calls..it helps turning it off in my house because I don't get great reception so its not always looking for that 3g

Thanks. Is that only 1G? That's partially what I want. Better would be to be able to get 2G which would be ok for web browsing. 1x is painfully slow and useless. I'd like to be able to switch to 3x just for streaming video, downloading, or other high data needs.

Yes.
Hold power down.
I think ATT when you turn off 3g it goes to 2g.but if um not using 3g I keep it in 1x

If you still have sense, there is a widget from the settings that you can add to do this instead of having to hit the power button. Make it a 1 step process!

So it is not possible to shut off 3G and keep 2G?

analog = 1Gen network
1X = 2Gen network
EVDO = 3Gen network
EDGE is GSM 2G, does not apply to this discussion.

No.
An easy way to see what you can and can't do is to install the HTC Widgets (found under "Widgets", then "Settings").
The one's relevant to the topic are:
Mobile Network and Wi-Fi.
I also use Bluetooth and GPS widgets, and between the four, manage battery consumption as best I can depending upon what I'm doing and whether or not I have wi-fi coverage available. If I'm just doing calls and SMS text messaging, I turn them all off.

OK. Thanks all

Incredible. The OP is looking for wireless data (see his post #5) when 3G is off. If you can do that, post a how-to. When I disable 3G and wi-fi, I get 1x - which is 2G, as explained - but isn't what the OP is trying to ask for (but getting terminology mixed up).

Hidden menu?

Is there a hidden menu for the glide? I want to try to disable 4g cuz its killin my battery

Are you running the Inc3ption rom?
To turn it off, you have to go to Settings > Wireless and Networks > Mobile Network > Uncheck use packet data. But you can get an app which allows you to control when the data is on or off and put a widget on the homescreen so you can turn it off/on asap instead of going through the method I gave you.

Runnin stock... i just wanna turn 4g off but have 3g on.. im on straight talk and ithink ots killin my battery cuz its sayin 97% without signal

Captivate glide doesn't have 4g.. It only has 3.5g. You can't go down to 3g manually.

3.9G or 3G++ if you want to be accurate. But it doesn't matter, and I imagine he would want Edge to save more battery.
But I remember reading that it was not possible on the AT&T ROM. I think disabling sync when you don't need it could help a little.

you can try:
- open dialer
- dial *#*#4636#*#*
- tap Phone Information
- scroll down to "Set preferred network type" (or similar)
- tap drop down and select "GSM only" or "GSM auto" if you want EDGE
oh one more thing, I have no idea if this persist upon reboot....sorry

I have the Rogers stock and I select 2G from the Settings -> Wireless and Network -> Mobile Networks -> Network Mode -> GSM only
This allows me at work to only use Edge as I have crappy reception at work and it keeps alternating from 2G to 4g (what the phone shows on top middle) Now I simply see an E and battery life is much better. I switch it when I leave work back to (GSM/HSPA(Auto mode)
You mentioned a widget that can do this from the home screen??? This I would like.

Samsung website says it a 4g phone???
Sent from my SAMSUNG-SGH-I927 using Tapatalk

^^^^^^
It is just 3.75G and NOT real 4G... Further in AT&T stock ROM, there is NO way to disable 3G/HSPA or set 2G only... Even the *#*#4636#*#* method is NOT working, as I have tried that too...
Just flash the ROGER's ROM or any other Custom ROM here (Rooted_Rogers_stock, Osimood, inc3ption, etc) and you can select HSPA only (for fast data on good 3G coverage) or GSM only (to save battery in spotty 3G coverage area) and Auto mode also...
Further I use one app which stays in Notification bar showing current network and on clicking it, the above-said option will be shown (otherwise you have to goto Settings-->Wireless & Network-->Mobile Networks) and you can also enable/disable data on that same page... The app is called "Show and Switch 2G/3G" and its available in Google Play Store --> here....

It's actually 3.623G if you want to be precise.
;-)
Actually compared to LTE speeds it's downright slow. But it's more than enough for most people.
Faster speeds just means you hit your data cap sooner....

Where did my 4G go!

I live in area that does not have 4 g so it stays off, however today at airport I tried and no 4G toggle anywhere! Where did it go, I swore when I got s3 I tested 4G but now it's gone? Thanks for help.

GS3 doent have a 4g "toggle" as you say...but you can make sure its enabled
settings-->more settings-->Mobile Network-->Network mode.
Preferred network mode should be set to "CDMA/LTE/EVDO"
If you have "CDMA/LTE/EVDO" enabled, anytime your in a Sprint LTE area your phone icon will switch from 3g to 4g.

it shouldnt chew up ure bttery at all, as all it does is search the network for 4gLTE and if it doesnt find it, it will automaticly go to sleep and try again like 2 or 3 hours later or periodically as it tells u. .however u do need to have sprint automatic connention left on in order for that work. atleast thats what i got from reading the sprint connection optimizer information it gave me.

The optimizer isn't for the LTE. I hate that garbage so I always leave it off. As long as your preferred network is set as stated above, it will automatically switch between them. Side note though, it may switch back to 3g if you don't have a very strong 4 g signal. It likes to be weird.

Sounds like your thinking of a wimax phone. I I had a Motorola Photon and you had to physically turn 4g on and off on it.... I think most wimax 4g phones are that way.
Sent from my SPH-L710 using xda app-developers app

Do any of the custom ROMS have a toggle for 4g/3g? I live in a 4g area but sometimes the signal isn't strong enough so it goes to 3g. Quite annoying. It would be great to toggle 3g off and force 4g.

So I had s2 before s3, so I assume the s2 was a 4 -g wimax? It had a toggle widget.

Have you tried updating to the new radio? I believe they boosted the power to give slightly better LTE connectivity in those kinds of environments.

There is a way to force LTE on the GS3. I did it with mine so that I could map out the LTE zones with sensorly a bit easier while I was driving over the weekend. The way I was able to do this is you need to have Nova Launcher downloaded and installed.
Once you do this, long press on the home screen and go to "Shortcuts".
Next click on "Activities"
Next scroll down to "IOTHiddenMenu"
Then scroll down and click on "IOTHiddenMenu : HDR1X_Selection"
Doing this will allow you to force LTE only mode. Keep in mind you WILL NOT be able to make any phone calls while doing this. For some reason the GS3 requires the phone to be in LTE + CDMA + EVDO Mode to make calls even if you have a very strong LTE signal.
Another app I would recommend downloading is called OpenSignalMaps. Once you have the LTE only mode turned on or even the normal LTE + CDMA mode, you can use this app to refresh your network by clicking the little refresh button at the bottom left of the app in the Overview tab. What this does is pretty much turn your phones mobile networks on and off and then scan for LTE first before scanning for EVDO. I have been able to connect to many more LTE sites by doing this. Even ones that are fairly far away.
Hope this all helps. Let me know if you have any extra questions.

No data connection at all
I have the settings on GSM/HSPA/LTE, but lost data connection completely. Tried to restart and turned on/off flight mode - still no data. Voice in and out is OK. I finally managed to reconnect by repeating the process. Is there a better way to reconnect?
Thanks.

Check out "Network"

with the latest l13 radio my phone will not stay on 4g it is heavily biased to 3g and I do not know how to fix it. I am right next to the 4g towers.. ... any thoughts? Thanks

Thanks
Thanks. Unfortunately, the "Network" app would not run. So I followed a similar line, and found "3G Reconnect". It does not fix the connection issue. Any other thoughts?

Is it possible to switch 3g->2g if I turn on Wifi and wise versa?

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!

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.

How to Force Galaxy W (Android 4.2.2) to Use Only 3G?

I was testing this on my W cause it keeps going the H all the time and sick of it.
"It would be on 3G but as soon as I open say Google Play or the Browser it would go to H,H is HSDPA."
Access Android Testing Menu
Go to Galaxy W and type *#*#4636#*#*
It will open the Android testing menu.
There you have several category of information. Tap on phone information.
Scroll down there and you can find set preferred network type.
Set it to WCDMA only,
Now your Galaxy W is in force 3G mode. It will never switch to 2G.
The problem is solved and we just forced Android to use only 3G. But Remember, in a situation where you don’t have 3G signals at all, you will be totally cut off from data networks. In such case if you need to use 2G EDGE connectivity, set preferred network type back to “WCDMA preferred”. If you restart your Galaxy W this setting will go back to default.

Just a comment. I hope you know that High-Speed Downlink Pocket Acess (hsdpa) is an enhanced 3G protocol. So its faster than 3G. Another thing, no need to restart after changing the value. If you notice, right after changing it, the radio signal resets. Then it goes back on. Just a comment.

But what about quick settings? There you have an option to set the network to 2G, 3G and both, no?

When using a CyanogenMod-based ROM, one can create a Notification Drawer toggle which will shift between 2G-only, 3G-only, or 2G/3G.

How come?? if the place has no 3g signals?
