Cell Standby

[pvella]

Read this on xda about a process consuming a lot of battery. Just wondering if this applies to our favourite tablet!!!

[SCRIPT] Remove Cell Standby Service (Super Battery Life!) - xda-developers


adb shell mv /system/app/Phone.apk /system/app/Phone.OLD
adb shell mv /system/app/TelephonyProvider.apk /system/app/TelephonyProvider.OLD
adb reboot
This was specifically for the Nook. This might break the S7 GSM possibly.

What do you think ?

Look at your battery usage, if cell standby is there and using a large % of your battery then this might help. I have no cell service and therefore no cell standby

Have you tried this yet?

I was thinking about trying this. I keep my tablet in airplane mode, but this would be even better if I could just remove the phone. I have nettalk on my tablet and don't plan on ever adding a cell/data plan to my tablet. I was just going to see if anyone saw a change. I may give it a shoot tonight.

OK, so was I bored at lunch so I tried this through terminal emulator and can confirm it did NOT work for me. On the reboot I got a bunch of errors and then everything looked fine. Then I went in to take my tablet out of airplane mode and it would just try to do it, but would not. Then I tried to use the power button to turn the screen off and nothing. Then I went back in to terminal emulator and I could not get super user permissions. I went in to root explorer and renamed the files back to .apk and did a battery pull. On the reboot, no problems and everything works correctly again. It is a great idea, but I think there is too much tied to these for us to be able to do it.

I use this trick: http://www.androidtablets.net/forum...eatures-tablet-enable-wifi-airplane-mode.html

No root required. Might not be exactly what you want though, but this allows me to toggle my phone radios off.

Be careful renaming Phone.apk. There are programs that depend on some of its methods. You can safely rename TelephonyProvider.apk, but you'll get a FC loop and will have to reboot. After that's been done, you'll have to test your gsm data to make sure TelephonyProvider.apk wasn't serving your data connection.
