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?

It would actually get quite cold, at 16000' you can expect the air to be well below 0 (pick your units, it's fuckin cold).

The only time heating becomes an issue is at supersonic velocities and is due more to compression of the atmosphere against the object then actual friction.

The terminal velocity of a tumbling iPhone won’t be high (about 70km/hour, according to ht…

It's almost as if the laws of physics align entirely with the observed result! Baffling!

Kelvin

In all seriousness, it can be down to -70 degrees Celsius.

Drag (air friction) is proportional to the square of velocity. If you know aerodynamic properties of iphone, you could find a value of velocity where drag is equal to gravitational force, at which point the speed doesn't change. You could use it as an approximation of the speed at which iphone hits the ground.

Crazy considering multiple iPhones (latest being an iPhone 11) haven't survived a few feet fall for me (no case...I'm extremely particular about using a case now).

Must be a U-shaped curve of survival rate versus drop height.

If the iPhone self-stabilized an acceleration maneuver while using its charging port speakers to build acceleration while playing Metallica, maybe it could reach the sound barrier and truly self-destruct.

Realistically it's more of a rounded L shape. Once you reach terminal velocity, you're not getting any more energy.

Then all you need is to get really lucky and/or hit something relatively soft, like grass on some less-dense ground.

There was a death at 20mph around our area though, because of no seatbelt. It was specifically shown at the course to attain the driver's license.

It was also a choice; life is full of risks, having stuff (or even worse, other people) decide for me which I should prioritize drives me bonkers. The same person who's super disciplined about seat belts likely takes other risks that another person would deem at least as serious. Having an optional reminder feature is great; forcing it, not so much.

We already legally force it in almost every state on public roads because it's not about you, it's about everybody else minding their own business getting killed by your choices.

Doesn't take much FOD on the highway for your unbuckled body to slam into something and now you have a driverless vehicle. Also every else in your car should be bucked too so you're not bumping noggins.
