Apple is considering switching from titanium to aluminum for the chassis of the iPhone 17 Pro and Pro Max, aiming to enhance the design and reduce the environmental impact of the devices.
Summary of essential information to understand
- iPhones 17 Pro and Pro Max can swap aluminum with titanium.
- Apple’s change is connected to its aim to decrease its carbon footprint.
- Wired charging can now reach up to 35W, a slight upgrade from earlier versions.
What differences occur with aluminum?
iPhone Pro models currently utilize titanium, a premium and lightweight material. Analyst Jeff Pu suggests that the titanium structure should be reserved for the iPhone 17 Air/Slim model in smaller quantities, as aluminum has a smaller carbon footprint which aligns with Apple’s goal of achieving carbon neutrality by 2030.
Jon Prosser, a leaker, further supported this information by stating that the prototypes he viewed feature a distinctive aluminum body with no noticeable divisions between the edges and the back.
The most recent versions I’ve seen do, in fact, feature a unibody aluminum. No visible separation between the edges of the phone and the back. https://t.co/vfSlR7VDDz

The latest versions I have observed indeed come with a single-piece aluminum body, with no apparent gap between the phone’s edges and the back.
MacRumors also highlighted the enhancement in quick wired charging capacity to 35W, a slight improvement compared to the iPhone 16 Pro’s 30W. The iPhone 16 Pro Max, on the other hand, hit 37W in tests but maintained a lower consistent speed.
MagSafe still offers wireless charging speeds of up to 25W in the newest models.
Sorry, but I need the actual text you would like me to paraphrase in order to provide you with the paraphrased version.
