Lots of our battery powered devices have a bunch of literal antennas, though. I actually don’t know the frequency ranges on which an EMP can be expected to “pump out” significant amounts of energy, but if there’s enough in the bands where WiFi, Bluetooth, GPS etc operate that’s going to fry devices that don’t have some sort of protection built in. I also have no clue how common it is for radio modules used in consumer stuff to protect against voltage surges on their antennas, but somehow I’d imagine it’s not very common.
