Isn't that device a Faraday cage? And if you are in war zone - using a phone with removable battery is absolutely mandatory IMO.

  As nfjstjstns notes, very often there is "a small second battery connected to the baseband for emergency purposes".

    This is entirely false for most modern phones

        I've opened many phones and have one open in front of me. I have schematics of a few open too. Some have supercaps for RTC. No extra batteries.

          Show me a picture on a teardown on ifixit with this in a nexus phone? Or in an iPhone? No? Yeah...
