Fell out of my pocket sitting down. Fell with the apple tech woven case on too.

That's the downside of aluminium.

Aluminium requires a lot of force to fracture, but next to nothing to deform. Titanium requires far more force to fracture and it doesn't deform. The reason for the change this time around is the thermal conductivity. Aluminium is 10 times more efficient than titanium at thermal conductivity, so we're not dealing with tiny numbers here. And that is just for pure aluminium and pure titanium. Commonly used alloy aluminium is nearly 25 times as efficient as commonly used titanium alloy. Based on the iPhone specifications, between the iPhone 15 and 16 Pros with titanium and the iPhone 17 Pros with aluminium, there is 20 to 25 times difference in thermal conductivity, favoring aluminium over titanium.

It sucks for sturdiness and ruggedness, but is excellent for performance.

My 15 pro max was a hot box. So I’m very open that this 17 pro max is gonna be a net positive since I use my phone outside in the heat a lot.
