For the Faraday bag, see <http://www.instructables.com/id/RFID-Secure-Wallet/>. It's easy to test. Just put the phone in the bag, and call it. If it rings, there are leaks.

I am noob at smartphones, but isn't this very close to functionally equivalent to just physically remove the battery from the phone? At what distance is phone with removed battery detectable? Well, if someone implanted "backup battery" this fails, but the implanted battery must be sufficiently small to not see it.
