Apple iPhone 15 Pro models said to feature all-new titanium chassis

The iPhone 15 Pro and iPhone 15 Pro Max or iPhone 15 Ultra are widely rumored to feature an all-new titanium chassis, which would be a major design change for the iPhone. Titanium is lighter and more durable than stainless steel, which could make the iPhone 15 Pro models more comfortable to hold, but also more resistant to damage. It would also be a significant upgrade from the stainless steel design that has been used on the iPhone since the seminal iPhone X in 2017.
