Hello all, I have been using the d2spr for quite some time... without mobile. I have no service on the phone and have no problems using it as an esspresso device like my p5113 tab 2. On my tab two there was a thread about removing the cell from the device, which I will more than likely have to look up again for that device. Is this possible for this phone? Anyone have any experience removing cell from the phone. I have read that searching for signal reduces the battery life, and I have yet to try it on the phone. If anyone can give me any pointers on this would be great. Also if you know which files to delete would save me a crap load of time searching for it.... thanks in advance...

are you basically trying to use it as a galaxy player? (i.e. an android version of an ipod touch?) if so, ive just put mine into airplane mode and turned wifi on manually. It greatly improves battery life as its not using the cell radio.

not exactly I use it as a voip phone and remote control as well as play various games, though there is no service on it, it shows the mobile connection. With the tablet it was a wifi only tab so removing cellular feature from android really increased battery life. Though I was not sure if it would work the same on the d2spr... not quite sure where to start though so thought I would ask, but thanks for the alternative, I am not sure about using airplane and wifi together as I have not tried that before.

gotcha. well, if youre using strictly voip, then the airplane mode and then turning wifi back on separately will work very well. like i said, ive done that with other devices and it substantially increases the battery life. Give it a whirl, what can it hurt?

Just an update with the steps on what I did.. as well as the results. With rooted device I deleted the 3 folders telecom, telephone, and another that starts with a tele that I can not think of. They are located in system/priv-app folder on root of system. (Using root explorer) After that I reboot, and all is working fine with no cellular at all. I have been letting it sit just to see how long the battery lasts on standby. So far I am at 28 and a half hours... I still get notifications and wifi works smooth. In the battery section in settings it currently reads charge remaining 8 days. Anyone with no service like me might want to give it a try... if something does not work all you have to do is re-flash what ever rom you had and that will put the folders back. and install cellular on the phone again... I would say that is the number one battery drain of the phone next to the display...

Day seven of my battery test and So far it appears that without cellular on the d2 you can get up to 10 days of standby charge. I did not use the phone at all for anything but to check status. Also, If you notice the small change in the curve, it is because it downloaded updates. It was connected to the internet the entire time...
