Apple Moves On from Titanium: Aluminum Pro iPhones Boost Cooling and Battery Life
Apple shifted the Pro lineup from a titanium frame to an aluminum unibody with a vapor chamber in the iPhone 17 Pro, citing improved heat dissipation and longer sustained performance (up to 40% better in some tasks). Titanium remains used in the iPhone Air, but for Pro models aluminum offers design and thermal advantages, including room for a larger camera module and bigger battery, suggesting titanium may not return to the Pro line for now.
