[Q] how to turn my phone off with wifi on?

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.

[Q Solved] Nonactivated 3G

If I haven't activated 3G, does that mean the radio is disabled, or could it be still using battery power?

Put it in airplane mode then enable WiFi, then the only radio that's on is your WiFi radio. That's what I do on my deactivated Droid, otherwise its looking for 3g...

I forgot all about doing that on my Xoom. I did that just now, since my 3g has not been activated.
Awesome! Thanks for reminding me about that.

Yeah, originally I didn't do anything about it....but then I was thinking that maybe it was using some battery so I enabled airplane mode. Battery has been much better. Hopefully there will be a ROM or some other way to disable it in the code, so that I don't have to leave airplane on.

You can also disable mobile service in the settings. It's preferable since doesn't airplane mode also disable gps?

If you go into Settings in Wireless and Networks, if Airplane mode is turned off you can choose Mobile Networks and turn off data selected.
That should stop the antenna from activating without using Airplane mode.

I tried that originally and the battery monitor still showed the 3G radio being on. Also even doing that it still prompts on every reboot to be activated while in airplane mode it doesn't

My understanding though is that this will ONLY disable data. It won't disable the physical radio that connects to the cell network. And as long as that radio is enabled (even if data is disabled) it will contribute to the draining of your battery. By putting the device in airplane mode, it will actually disable the RADIO, not just the data coming in through the radio.

I just switched to Airplane mode. Let's see if this will help battery life (not that I had to complain anyway)

Originally after about 30 hours I would have around 20% battery left. After enabling airplane mode I have 86% battery left after 1 day and 7 hours. I think it makes a big difference.

So is this right? The only way to disable the radio is to actually enable airplane mode and then turn wifi back on? Will the GPS still work?

I found with mine just on standby I used 17% battery in Cell Standby. I went into Mobile network settings and unchecked Data Enabled and it dropped considerably, down to about 3% (still while I hadn't been using the Xoom).
I'm going to try airplane mode tonight.

Is there any hope to activate 3G? I am living in europe (Denmark) and here is no verzion.

New Note unable to connect to wifi

Hi, I have enabled Airplane mode and WiFi. However, I still cannot use WiFi at home. In particular, the device keeps scanning for network connection. After I chose my home network, it stayed there for about a second "remembered". Then, when the device started scanning again, my home network connection was disabled. Since I cannot connect to the network for more than a second, I cannot use WiFi yet. Is there something wrong with my new device? Please help.
P.S. For some reason, Mobile Network, Bluetooth Settings and Call are dimmed. I don't use 3G.

You need to turn off airplane mode, having it on blocks all network activity.

Actually not true, I can still connect to wifi when on airplane mode. If your in an airplane and there is wifi than this helps switching the phone to airplane mode than just using the provided wifi.
Anyways about the wifi, looks like it could be your modem settings if you changed them recently, if you didn't change them, forget your network on your phone and re add your network which will refresh your modem's settings. After this it should connect fine

[Q] How to turn off cellular radio on N7 3G

I must be missing it somewhere, but I cannot seem to find where to turn off just the cellular radio on the N7 3G.
To save battery, I'd like to turn off the cellular radio and only use Wi-Fi when I'm at home. I can go into settings, and under Wireless and Networks I can go into Data usage and turn off mobile data there, but I still get a status bar icon with signal strength for cellular. That leads me to believe the radio is still powered on and scanning for a signal. That has to use some power.
I found I can turn on Airplane mode which turns off everything and then turn Wi-Fi back on. This seems like a really strange way to turn off the cellular radio. Every other device I've had there was a place to turn the cellular radio on and off. So then when away from home I can turn off Airplane mode and turn off Wi-Fi.
If anyone has a better way to do this, let me know.
I'm running a stock 4.2 ROM that has been rooted.

The airplane + WiFi method is the one I've always used on Androids. Are there other Androids with such an option in the standard user facing menus?
Anyway in the Testing menu (easy way to access is with the app "Phone Info") under Tablet information there is a "turn off radio" button. That seems to kill the cell signal while leaving WiFi on. Go back to the same place to turn it back on.

To get to the testing menu go to the play store and install

My HTC One X has an entry for Mobile Networks with an on/off control near the top on my settings screen. HTC also supplies widgets to toggle on and off all the radios of their phones. There is one called Mobile Network that will toggle the cellular radio.
Has anyone seen a set of widgets that I can install to toggle Wi-Fi, Bluetooth, GPS, NFC, and the Mobile Network that works with the N7 3G? To conserve battery, I prefer to turn off the ones I'm not using.
For instance, with only Wi-Fi enabled, three email accounts syncing, plus Facebook and Twitter, my battery drain is about 0.5% per hour. If I leave the cellular radio and GPS enabled, it jumps to about 1.7% per hour. These numbers are when sitting idle with the screen off. I haven't tried enabling Bluetooth and NFC to see how much they increase the drain.
I only enable the radios I need to conserve battery. I'm just looking for an easier way to do it. Currently I have to go through several steps.

Wifi networks don't show up in airplane mode but do when airplane mode off

this has been very vexing mainly because I don't know how to craft the google-fu to get beyond "no wifi in air plane mode".
Basically, when you turn on airplane mode it disables wifi. You can then enable it an all is good. However, for me it appears that when you disconnect from a wifi network in airplane mode the wifi network can no longer be connected. Once you turn airplane mode the wifi network comes back up but if you enable it the wifi network is gone. Other wifi networks are still there in both modes but just not the one you forgot.
Using wifi analyzer the wifi network is still being detected by the phone but the phone won't connect.
Any thoughts on how to solve this one?

For future readers it appears that if you run into this issue you can turn off airplane mode connect and then turn airplane mode on again and it will work. Sometimes. This is my solution until I can figure out what the heck is actually happening.
