Apple took a bold step this year with the release of the iPhone 17 series, introducing a major redesign and a shift from titanium to aluminum in the Pro models. The new aluminum finish promises better heat dissipation, and its durability was put to the test by the PhoneBuff team through a series of rigorous drop tests.
In a showdown of durability, the iPhone 17 Pro Max faced off against the Samsung Galaxy S25 Ultra, which boasts a titanium alloy frame. Both materials have their strengths and weaknesses, and the drop tests revealed interesting insights into how each phone handles impact.
The comprehensive set of six drop tests simulated real-world scenarios, including drops on the back, corners, and front of the phones from various heights. Surprisingly, the results ended in a tie, showcasing the unique characteristics of each material.
When dropped on its back, the iPhone 17 Pro Max’s aluminum body proved to be more resilient, absorbing the impact and resulting in cracked rear glass while leaving the camera lenses mostly unscathed. In contrast, the Galaxy S25 Ultra’s titanium frame transferred the force more directly, causing more significant damage to its back glass and telephoto camera’s autofocus unit.
However, the corner drop test revealed a different story. The softer aluminum of the iPhone 17 Pro Max showed visible scuffs and a dent from the impact, while the titanium alloy of the Galaxy S25 Ultra remained virtually unscathed, demonstrating exceptional durability.
Front-facing drop tests from both phones at one and a half meters yielded similar outcomes, with both screens cracking and the damage spreading across the display. Despite the shattered glass, Face ID on the iPhone and the in-display fingerprint sensor on the Galaxy S25 Ultra continued to function as expected.
The tests underscore the trade-offs between aluminum and titanium. Aluminum’s malleability allows it to absorb impact and protect internal components and glass from certain falls but makes it susceptible to scuffs and scratches. On the other hand, titanium alloy is more resistant to direct hits but can cause more extensive damage to glass due to the way it transfers force.
Overall, the drop tests showcased the strengths and weaknesses of both materials, providing valuable insights for consumers looking for durable smartphones.
