Once it reaches its maximum velocity the altitude doesnt really matter. However I dont know how to calculate that maximum velocity and the minimum required altitute.

From the very short snippet I can read (paywall) I dont know if the phone landed in concrete or not.

What about the heat? If the fall is longer won't the phone heat up more?

This isn't much more than the original twitter post: https://nitter.net/SeanSafyre/status/1744138937239822685

The most astonishing thing to me is the destroyed charger cable.

Also a good reminder that it's a very good idea to have the screen lock after a set time — even if it's long.

And yet the air rushing past provides cooling....

Maybe you're thinking about an iPhone de-orbiting from ISS. That would be a different story.

Nope, at the altitude planes are at, the atmosphere is much much colder than at ground level. Along with that the terminal velocity of the phone is going to be under the speed of sound so there won't really be any meaningful compression going on to heat up the air around it like you get with a descent from space. That heating essentially happens (this is simplified) because a space craft is going much faster than it's terminal velocity at the given altitudes it's passing through so it compresses the air below it, heating it just like you'd expect from the ideal gas law. It happens to be that it heats it so much that it makes a super-heated plasma so you end up with what looks like fire (not sure if there's actual combustion happening, but i wouldn't be shocked) surrounding the craft. That's also why once it's slowed down by the friction and air resistance, the plasma dissipates and is no longer a problem for re-entry.

Now if we were to launch the phone at several times the speed of sound we could probably get the same thing to happen but I'm doubtful that a phone could survive the acceleration in the first place.

At the terminal velocity of an iPhone, the air passing through will do more to cool it than to heat it up due to friction.
