I just recently upgraded from a Samsung Galaxy Player 4.0" to a Moto G. I sold my SGP and accessories for almost what I paid for my Moto G, which I considered a pretty good deal. I currently have no need for a cell phone, however, and merely use the Moto G as I did the SGP. That means connecting with WiFi only and using it mostly as a media and navigational device (with pre-downloaded maps and GPS enabled).
In an attempt to conserve as much of the (already amazing) battery life as possible, I've set location to Battery Saver and disabled "Data enabled" and "Data roaming" under Settings>Wireless & networks>Mobile network settings. I've also set "Battery Saver" under Settings>Battery to "On". Despite this "Cell standby" under Settings>Battery still consumes an average 20% of a full charge of my battery. Part of this could be that as I am in a remote location, with only very weak cell signals available, the device is constantly searching for signal despite the fact that I do not even have a SIM card installed.
Is there any possible manner in which I could switch off the cellular modem in the phone without switching off WiFi? I can set the device to "Airplane Mode" but that also turns off WiFi, which I prefer to leave on during the day and only switch off at night. I am very new to Android 4.x, so do not yet know all the ins and outs of the Settings menu, and as such may be missing something. Or there might just not be the option. Either way, is what I am wanting to do possible?
