I temporarily use *#*#4636#*#* to force my phone to EDGE/GSM only. I can get 4-5 days on the battery and can stay on top of my email/whatsapp with light data use that doesn't require high speed. It's great when I'm traveling/vacation. Problem is this setting doesn't stick. If I restart the phone, it switches back to 4g LTE and if I forget to toggle to 2G mode, it drains the battery.
Any permanent solution to address this?
Some roms have it baked into network settings where you can select the network type... only helps if your rooted though....

Something strange since my upgrade to 1.66 - when the phone's in standby it appears to be establishing an active 3G connection, and when i wake (unlock) the phone, you can watch as it reconnects to the current wifi connection again. Is this some sort of energy saving strategy, which could theoretically run your 3G bill up? (dont matter to me as mine is unlimited, but not all are).
Anyone else notice/know about this?
By default, Wifi is disabled during standby to save power. So if a program requests an internet connection, for example outlook if you configured it to check mail automatically, the phone will connect the data connection.
You can search for "wifinostandby" to find a fix that disables auto wifi power off.
But beware that current consumption with wifi on is substantially higher than when it's off, by 10 times (current draw is about 50mA vs 5 for "true" standby), meaning you get at best 30h standby life if doing nothing else.
Also, dont forget that the top bar shows you the connetion being offered by your network, it doesn't necessarily mean it's doing anything. If you disable the wifif you see the same 3g icon regardless of what data is doing. So as said above, you go to standby, wifi is disabled so the wifi icon vanishes, then if you have your phone in 3g mode (personally mine stays in gsm mode, so i see an E not a H) when you wake it up it will display the H before the wifi kicks in and the icon changes back to wifi again.
This is not about HOW TO DISABLE the data connection: I know there are plenty of ways and apps to do that, even automatically.
As regards me I have two manual options to do that on my phone:
1. In the Comm manager, under Wireless Controls, I have 3G on/off option, which I can use to switch between 3G and 2G network
2. ModaCo NoData, which I can use to ENABLE/DISABLE my "H3G Internet" data connection
My questions are:
a] do I have to use both?
b] if either one is enough, which one is the best (or: what is the difference between the two)?
Thanks
I believe if you are on the 2G network, you can still connect to the internet via GPRS?

This does what it says, switches your phone from 3G/2G networks to 2G only. But in both cases your phone can place a data connection, only it will be slower when on 2G (GPRS/EDGE).
To disable the connection, you need to use nodata. The other option does nothing in this regard.
So in the end your question still actually was about how to disable
Fine understood
New question then: considering that I have automatic wetaher/location/facebook.pushmail active, if I disable data connection at night and in the office, would this save battery life?
Most likely a little,yes. But data connection barely uses anything when idle, so you save the little amount of traffic that takes place from the updates. And the phone will still wake up at the update intervals to try and connect, which drains pretty much the same as the connection itself.
i signed the data plan only contract with UK O2. they block the calling feature on my dell streak which i only can send and receive text.
I am looking for a way to turn off phone module at the mean time keeping wifi on. unfortunately, seem i only can turn phone module off by setting in airplane mode. in such case, i can't use wifi for surfing.
is there any way around this? thx in advance!
Tap the battery icon in the top bar. This should bring down a menu, tap the tick box next to 3G, EDGE, GPRS networks. This will turn off the phone network data connection and leave the Wi-fi on.
This is sadly the closest to getting the phone to how you want, other than taking the sim card out.
I've noticed this problem on a Samsung Captivate and can put it in airplane mode (which also turns off wifi) and then separately turn wifi back on without changing phone.
You can do it with 2.1 rom, I'm using it now to type this..
put it in airplane mode.
then go to settings, wireless networks, wifi and turn it on .
the quick dropdown menu (from the signal status) will also let you turn wifi on when its in airplane mode but not on the 1.6 rom unfortunately.
i c. it's the ROM! damn...
u r right. when yr phone in airplane mode, it won't get charged at all.
Here is the way to set Sprint Galaxy Tab to wi-fi only. This works with both rooted and unrooted tabs but rooted is way better because of titanium backup. Batch backup everything with titanium backup. Then go to SETTINGS/PRIVACY and erase all data. Follow all prompts and reset device. When device resets and comes to first screen about keyboard, skip this step and when you get to Sprint and Wi-Fi : Wi-Fi only set to Wi-Fi only!!! (Very Important Step). Continue through setup of phone if desired. If you use titanium backup, (Important Step) restore missing apps and data but NOT ANY SYSTEM DATA!!! Reconfigure apps and good to go. Remember, Pick Wi-Fi only and NOT Wi-Fi and 3g.. Also remember if using titanium backup to NOT RESTORE ANY SYSTEM DATA, only missing apps and data. Tested and works great.I use Mobile Hotspot from Evo to power Galaxy Tab and $30 dollars for Hotspot unlimited on 4G AND 3G makes capped 3G on Tab useless. I hope this helps...

Why not just set it to Airplane mode first, then go to menu, settings, wireless and networks and just turn on only WiFI???

I set to airplane mode, then went to menu, settings, wireless and networks and checked wi-fi. Problem was, when you left the range of your router, it would automatically switch to 3g so that you can have continous connection and that was the function that I wanted to disable. This was something I noticed and it all started with the initial device setup which gave you the option of totally disabling 3g on the device. That way, it either runs on my router at home or from my Evo as a hotspot and not the 2gb capped Sprint service included.

I found the setting to turn on or off 3g. Settings/Wireless and networks/mobile networks/ and uncheck use packet data. Thanks for the information. Really helpful.
Long press the power button and deactivate data. Then turn on airplane mode. Then turn on wifi. Voila - no extra costs and better battery!
a ton of apps out there to do this too. apn on-off looks like a nice widget to give you one touch quick control.
this is not the same thing - editing the apn does not turn off the radio, only stops it from finding any network to connect to
airplane mode will literally switch the radio off, saving you battery and removing the cell signal notifier from the taskbar
Hi there,
so here's the issue.
every time I wake up in the morning and switch on my phone, I find the network set on 3g instead of 4g.
Needless to say that there's no problem connecting to LTE, it works flawlessly: all I need to do is navigate the settings menu to 'mobile network' and set 'preferred network mode' back to 'GSM/WCDMA/LTE auto'.
Is there any way to avoid this? has anyone had the same experience?
thanks!
