One thing this video implies is that no radios are on during airplane mode. Perhaps my terminology is imprecise but the passive GPS receiver can remain active. Still, its creepy (though unsurprising) that it uploads the data anyways.

BTW, having the GPS on must have been a massive battery drain. I know it is on my phone, especially for initial triangulation. I wonder if low power mode would help?

I guess I knew GPS was passive but I would have guessed - naively, it turns out - that "airplane mode" turns off all interfaces to the outside world.

Is there a way to toggle off the GPS on an android phone?

open the phone, find the chip, burn it out.

Faraday cage?

On iPhone, GPS is on in airplane mode as well (but you can just turn off the location services if you want).

You can set it to be off too in settings.
