I would guess that an iPhone would hit terminal velocity within about 100 feet or so.

Once it hits terminal velocity, it doesn’t matter if it falls 100 feet or 16,000 feet. It will still hit the ground with the same velocity.

Looks like it landed in some soft weeds....................

The flat shape of the phone would cause it to start rotating longitudinally as it fell, most likely. That would mitigate any excessive acceleration.

I wonder what Galileo would say about it.
