The duel is launched between the iPhone 15 and the iPhone 15 Pro, featuring a battle between aluminum and titanium. While titanium is often seen as the undisputed champion of lightness and strength, durability testing by JerryRigEverything shows a completely different picture.

Apple talked a lot about the benefits of titanium when announcing the iPhone 15 Pro. In this context, the comparison between Apple’s iPhone 15 and iPhone 15 Pro Max, made of aluminum and titanium respectively, offers interesting information on the robustness of these two metals. After the iPhone 15 Pro, JerryRigEverything tackled the iPhone 15 and 15 Plus.
The Ceramic Shield screen: a guarantee of scratch resistance
The screen of both versions of the new iPhone 15 benefits from Ceramic Shield d’Apple. This particularly durable material only shows visible scratches when exposed to elements with a hardness of at least seven on the Mohs scale.
As a reminder, the Mohs scale is an indicator of the hardness of minerals: it goes from 1 (talc) to 10 (diamond), seven corresponding to the hardness of quartz, a mineral renowned for its solidity. This means that the iPhone 15 screen is very resistant to everyday scratches.
Aluminum frame vs titanium frame: the match
Despite its aesthetic appeal and its lightness, titanium does not offer superior guarantees in terms of resistance, contrary to what one might believe.

Indeed, the aluminum frame of the classic iPhone 15, although less well protected against scratches, has superior resistance to torsion and bending. This effectively means that the iPhone 15 cannot be easily damaged or bent by force. Testing shows this is also true for the iPhone 15 Plus, despite its comparable size to the iPhone 15 Pro Max.
The strength of titanium is its weight
The titanium frame of the Pro models, despite its image as a robust and light material, does not make Apple’s smartphones more solid. Compared to the stainless steel frame of the previous year’s models, titanium does not provide increased strength. On the contrary, JerryRigEverything’s testing reveals that the Pro Max model, in particular, exhibits weaknesses during the bend test, leading to the glass back breaking.
