During our heatwave here in the EU, I’ve noticed that Apple is getting more and more generous in what the temperature is supposed to be. Here it is pictured side by side with the actual, measured temperature via a Kestrel 2000.
I suspect that this is AI being its usual solicitous self, continually making it better for people asking, ‘Is it cooler on the coast?’ It ain’t, by the way, same here as it is in Paris. That’s my theory, but I’m open to all conspiratorial suggestions.
My last phone from 2018 had like 48 sensors on it, including thermometer, so yeah that indeed is a thing. But obviously OP’s photo is showing Apple pulling numbers
out of thin airfrom whatever weather station, not from any internal sensors.
