Along with all the other patients, doctors and hospital staff you

I was more considering unwanted connections.

Connections 'to' A's phone over WiFi from some external device?

I'd say most peoples smartphones have WiFi on all the time, unless
they were specifically trying to save power etc?

Probably and even if on and searching for networks to connect to the
vast majority these days are encrypted and need a password before any
data connection is established (save for the one between the devices
to authenticate).

Of course having the thing hunting around all the time uses battery.
