Government spies can set up their own miniature cell network tower. Your phone automatically connects to it. Now, that tower's radio waves send a command to your phone's antennae: the base-band chip. That tells your phone to fake any shutdown and stay on.

That means the base-band processor is still running," said Pirc, now chief technology officer of the NSS Labs security research firm.It used to be that way, but no longer. They run RFID spy chips added on to the case of smart phones which require NO POWER from the battery to enable the system circuitry to be operational.
