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.
