An iPhone 12 weighs 164g [1], so, through the magic of the metric system, it needs to displace a minimum of 164ml of water to float.

The iPhone has an external volume of 14.67cm * 7.15cm * 0.74cm = 77.62cm^3 = 77.62ml. So it would need to be about 2x the volume to float.

Yeah thanks, I looked it up and got those numbers from calculations but wasn't sure if that was the right way to just calculate that because I am not familiar with it.

Time to roll back this innovation and release the new iphone with 2x volume so that it'd float.

Meet the new iPhone Air...

Lifeproof used to make an add-on life jacket that fit around their cases.

But then it would be heavier, and need to be even bigger than 2x.

Might be an idea for a magsafe attachment: a floater :)

There’s this anecdote of Steve Jobs saw a prototype for an iPod and dropped it in a water tank in order to proof his engineers that they could make it smaller, because it had bubbles of air coming out.

That’s an old urban legend which has been told about many people and companies.

The calculation pretty much boils down to changing the phone's weight in kg to a volume in l.
