My SGT7 does not have any SIM cards in it, I don't use it as my main phone, and will most likely never have to call 911 or other emergency numbers (from this tablet anyway). So pretty much, I have no need for the cell radio.
I want to just disable the cell radio from doing anything (from what I see, I've been on battery for 3hrs so far, and Cell standby is at 19%). The battery usage is probably not too bad at all, but having cell standby do nothing at all would be ideal.
An idea I had would be that when I restock to Gingerbread (via Overcome's guide), I just don't flash the modem file. Not sure if this would be a "good" idea or not though.
you can set to flight mode, then turn on wifi or bluetooth or gps or other radios at will.

Yea but to my knowledge, you have to do this every boot. I was rather hoping for something else :/
Is it CM9?
I am on Overcome 4.1 and the setting sticks on reboot.
Why don't you give it a quick try? Been using this since Roto JMI Froyo rom through all overcome series. I don't have a SIM card in my slot.

Hmm, I could of sworn on another ROM, that setting didn't stick. I'm on CM9 now though and the settings stick Thx!
I do the same. I have mine in airplane mode all the time. Wifi reconnects on reboot. Battery lasts days. Used to use it as phone with BT but got sick of carrying it with me everywhere.
I just tried this on Gingerbread (Hyperdroid) and the wireless doesn't automatically re-enable itself on reboot :/
Switching on Airplane mode is not an option for me to kill my cell standby/cellular radio standby 40% battery drain. My kid uses madden mobile (and other apps) and they will not run with airplane mode on. (Eventhough wifi is on and connected (and internet is working fine with the browser and other apps).
I need to switch off the cell standby (radio) that is using up 40% of a 10,000mah battery on this android tablet.
I found that going into your file explorer and changing all "tele***.apk" files to .bak instead will kill these dialers for searching for signals all day. Battery doctor can help some too. We use 4.4.2 KitKat. possibly download from play store 'toggle cell' and 'data on off'.
If you can find any other .apk files on your device like phone.apk or telephony.apk, these need to be disabled or changed to .bak
I am not sure what cell radio does for me. I occasionally use mobile phone but normally have it in flight mode. I do not use blue tooth or radio broadcasts. I stopped using GPS as it seems to drain the battery. Do I need cell radio and if not, how do I uninstall it?

I have a sprint galaxy tab I bought just to use with wifi, but I see cell bars on top and I dont want it using the cell radio at all since I wont ever be using it and need to conserve battery, anyway to shut off completely?
I cant do airplane mode because I need WiFi on
Take the SIM card out of it.
Otherwise turn packet data off & lock the radio to GSM only, uses very little power then.
3G no mas
I have/had the same issue. The other annoying aspect is that if you haven't activated the 3G, it attempts to FOREVER at every boot. I suggest Airplane mode. After you put the tab in Airplane mode, you can manually turn WiFi on, and not have to deal with the search for service you don't want taking up yer juice. That's at least what I did. I know there are other options for rooted tabs, but I'm too scurrrred to root mine...
This will do it.

Uhmm just turn airplane mode on, wiat 5 seconds, then turn wifi on. you're good to go.
some people don't get that the sprint GT is CDMA and don't have neither sim card nor APN.
I'm in the same situation, using the sprint GT as wifi-only in airplane mode.

I tried airplane mode before, but when it killed the wifi (as I expected), I started searching... I had searched all over for this simple procedure with no success until now.
I had recently purchased this Sprint tab under the description of being a wifi only. When I received it and saw that it was a Sprint, I did not care at first, since I live in Canada, until the battery started being drained very quickly in my poor cell reception basement because the CDMA phone could detect a weak cell signal. I know that any other CDMA phone I had would use all its power to latch onto a weak signal.
Thank you very much.
Airplane mode turn off the cellular radios. Sim cards have nothing to do with it. Both GSM and CDMA are affected by airplane mode the same way.
It will turn your device into a wifi tab.
I just select airplane mode then re-select wifi on. This shuts off the 3G but lets you surf wifi.

The problem with the Airplane Mode is that it also turns off Bluetooth. For some reason, unlike wifi Bluetooth can not be turned back on individually while airplane mode is selected. Any ideas anyone???
I FOUND THE ANSWER!!!!! EasySwitch Pro
This is a fabulous app that allows COMPLETE and SEPARATE control of your wireless radios.
EasySwitch Pro by SMARTDYNE
Uses a very simple and effective widget to switch settings.
Works great on Samsung Galaxy Tab!!!
Here's the link:

I'm not on my tab at the moment so I will do it from memory. For the data issue, if you hold down power, you will see a selection above airplane mode about something to do with data. Turn that off. When I was playing around with it I'm the past, you need to have the radio on (not airplane mode) in order for the GPS to lock. You can also, In settings, enable network location in the location section.
To get rid of the activation nag, note the icon in the notifications bar. See what it looks like? I used root explorer, rooted of course, to navigate to /system/app. Scroll down slowly until you see an apk that has the same green circle with a check mark inside it. Enter rw mode with root explorer. Add .old to the end of the filename. Reboot. No more nag. If you delete it, you cannot update to gingerbread. It needs to be running to get the update. You can disable it later. You also lose all update functions in the about my galaxy tab section.
I use Widgetsoid2.x it allows me to go airplane, enable/disable 3G, wifi, GPS and more. Can get it in Market.

Sigh, you have it wrong. Turn on Airplane mode, go back into Settings and turn on WiFi and Bluetooth. Simple as that.
The ONLY way you can't turn on Bluetooth in Airplane mode is from the drop down slider thingy in Android. If you go into Settings, you can turn on Bluetooth in Airplane mode.
whats up?
Still wishin to kill cell-radio-app =) Any new ideas except the airplane mode?
ps:GPS and Bluetooth don't work in this mode..
I tried selecting airplane mode and then turning back on WiFi. However, Galaxy Tab is still trying to activate the Sprint account I do not have or want to get.
use titanium.

Sprint Activate message disappear on my tab. You must be rooted to use titanium app.

i have the same issue, cant find a solution. trying apps just turn on airplane mode.
One of the big complaints from all published reviews is the lack of battery power - about 4 hours maximum. I have an idea I to present.
I have the T-Mobile version, but I use my S7 at home; in fact I never activated the device on T-Mobile. I think that part of the problem with battery drain is that one cannot turn off the 3G modem. The S7 automatically disables the connection to 3G when the WiFi connects, but the modem is still working (there is still a signal strength on the task bar).
From past experience with phones, that 3G modem drains a lot of power.
Does anyone know of a way to disable the modem itself? I'm not interested in rooting at this point, but maybe there is some setting I am missing?
If you load DJ_Steve's S7 ROM, there is a hack to disable the RIL. That gave me much better battery life.
I just leave mine in airplane mode with no SIM inserted, enable and disable wifi as needed.
First off, what's RIL?
Second, I've also heard that the cellular is trying to connect on the software side. Any truth to this?
I'm wondering how this tab might fare, battery-wise, with it not pinging for a cell signal and 3G (or 4G, depending on the signal you get, or both and only 1x active) off. Can you set it so only one radio is getting play? Also, can you set profiles so that one gets used over the other? Example:
Screen off = 2G only
Screen on = 3G only
Internet apps (such as browser and YouTube) = 4G only

One of the posts above indicates that he is using a hacked software version, and the battery life is indeed much better without 3G.
Using airplane mode would work if I was only using the device to read books, for example, but I generally use it for online work.
I think the replies confirm my suspicion that the 3G modem is drinking the juice. Not too much of a hassle since I keep it at home next to the charge cable, but (especially with that non standard charge cable) it will not be so good outside the house (unless one is using the T-Mobile 3G, but that takes $$).

I use mine similar to this but I have a sim card in as well. I have a widget for airplane mode and one for wifi on my main home screen. I have airplane mode and wifi enabled most of the time but when I am out and need data (not very often) I just disable airplane mode for a short time.
This works well and the battery life is more like a minor inconvenience.
To do this same thing manually I'm sure juice defender ultimate should work since you could set up profiles for wifi, 2g and 3g (disclaimer: I haven't tested that idea but some people on this forum have juice defender ultimate and might be able to comment)

The problem is that when the WiFi is on, so is the 3g. I confirmed this with my battery widget; 57% of the battery drain was due to the 3g modem IIRC.

If you activate wifi by turning airplane mode off then the 3g radio will stay on in the background while you are using wifi.
If you turn on airplane mode then wifi you will only have wifi active. Just make sure that the airplane mode symbol is on in the top right beside the wifi icon.

Thanks, I will try it tonight! That should improve my battery life a lot. I'll report back.
Wow,
That worked great. I didn't realize that flight mode did not override all radios. Thanks for the tip!

This has also worked for me with the SIM inserted. I get great sleep times with new OTA upgrade left at default settings and keeping the S7 in airplane mode, unless charging. I only turn on wifi when I need it.
Also very important: if you're using the S7 only with wifi, turn background sync off from the power widget, when you are setting the tablet aside for some time. I believe this is where the battery drain actually occurs. If background sync is left on, the S7 continues to try to update location services and your various accounts, even though airplane mode is on.
I have "slept" the S7 (airplane mode with wifi off and background sync off) when I get to work at about 90% charge and come back to it at the end of the day at 75%, ready for the commute home.

Im sure there are many people out there who bought their tab second hand on craigslist or ebay and ect.... thats my situation.
i have a galaxy vibrant, and am on the simple mobile unlimited plan. ($60 unlimited everything) so i dont use verizon because i tether to my tab using the vibrant. i noticed the radio taking up a good 8% of my battery after 3 hours of standby. so i wanted to disable this since i dont use it. after trying many different apps like apn on/off and others, i realized none work. then i found the solution to be ridiculously simple.
1. go to settings
2. go to wireless settings
3. Hit Airplane Mode ( But that kills wifi so damn)
4. go to wifi settings
5. Enable wifi (It enables wifi while still under airplane mode, thus killing the cdma radio)
there dilema resolved.
now im getting an extra 20% battery life over a full discharge. <3
good luck
Great Idea. THIS SHOULD BE A STICKY.
Just set up my Galaxy...
Thanks.
Good instructions for newbies, but an old topic. And you can't use bluetooth when you are in airplane mode.
Maybe switch.off mobile data. Also when not using toggle wifi off
Sent from my LG-P999 using XDA App
Or just dial *#*#4636#*#* and switch the radio off
I have to do after each reboot
Thanks guys!
You can also use the Airplane Mode Wi-Fi Tool app, I've been using it for awhile and it works perfectly. It sets it to airplane mode and allows you to use wi-fi in airplane mode. It also stays after reboot. It also allows you to use bluetooth in airplane mode, though I haven't tried this feature yet.

How can I disable "Cell Standby"?
I have an i9000 running Team ICSSGS RC4.2, and I want to disable the cellular radio completely. I use the device as an mp3 player, without a SIM Card.
I am getting 8-10% Battery Usage from Cell Standby.
I have tried disabling the following apk's, and rebooting:
mms.apk
phone.apk
telephony.provider.apk
voice.dialer.apk
nothing seems to get rid of it. I have looked up various ways of performing this same task but nothing seems to work at all.
Does anyone have any other ideas for me?
Thats why u have Airplane mode ryt?
Airplane mode does not seem to stop the cellular radio completely, i was mainly just seeing what other ways people might have to disable it.
So I am using a Nexus 6 on the Latest Tmo build (28E?) of Stock Rom and Stock Kernel Rooted, Encrypted.
Since the update that enabled wifi-calling for the N6 I have taken to setting my phone to airplane mode and turning on Wifi only to save battery since the signal at my house bounces back and forth from LTE to 3G and that murders my battery. Most of the time the signal strength graph shows blank and battery app correctly shows the cellular radios as having no on time. However, after being idle for a while (it would seem) the graph begins to show the signal strength as Red (no signal) and the cellular standby shows up in battery usage with the radios as being on (with no signal) and "active for a few seconds". Toggling airplane mode on and off usually restores them to showing up as off. Other times I never notice and it stays on for a few hours and goes back off on it's own. My main concern is that it seems to be activating the radio on it's own, my minor concern would be that my battery monitor app shows that it's using the battery. What could be causing this? I don't think it's a reporting glitch, because it shows up in both the system battery panel and a 3rd party one. If anyone has any thoughts or could point me towards a tool that could help me figure out what's turning on the radio when it's supposed to be off, please let me know. I've included photos from today showing what I'm talking about, the phone has been in airplane mode the whole time in these photos.
Thanks so much!

I think your issue is one of the reason why I cannot get Wifi Calling working at all. No matter what I do, my phone is holding onto a cellular network. Still trying to figure this out.

The best I can tell, "Android OS" is the only thing that shows any mobile packets sent or received so it's got to be a system thing.
If you have the myT-mobile app installed try uninstalling it I found that app totally screwed with my Nexus 6, turning WiFi on when I had no desire to use it.

Unfortunately that's not the fix. I don't have that app installed. Tmo is sending me a new SIM as I am also randomly having Wifi calling drop in and out even while my wifi is connected.
Does anyone know any app that would let me see specifically what app is engaging the mobile radio?
