iPhone 15 details revealed: titanium alloy body, grip feel better
From the looks of things, the iPhone 15 is definitely going to feel better in the hand this time than its predecessor, or at least Apple is reinforcing that detail as well.
According to the latest news, the rear edge of the iPhone 15 will be rounded off to form a new bezel similar to the bottom edge of Apple's latest 14-inch and 16-inch MacBook Pro models' cases.
For reference, the iPhone 14 model has a flat design with angular edges, which is reminiscent of the iPhone 4. The last model with curved edges was the iPhone 11 several years ago.
New information suggests that Apple's 2023 iPhone will have a titanium body with curved rear edges, replacing the existing square design.
This isn't the first time we've heard rumors claiming Apple will release a titanium iPhone. Apple recently investigated the feasibility of using titanium cases for its products, including patents related to the use of machined titanium with unique properties for future MacBooks, iPads and iPhones.
Compared to stainless steel, titanium is relatively hard, making it more resistant to scratches, and its hardness makes it durable enough to withstand bending.
Titanium's strength makes it difficult to etch and polish, so Apple has developed a sandblasting, etching and chemical process that can give the titanium case a high-gloss finish for a more attractive appearance. Apple has also been investigating the use of thin oxide surface coatings, which can reduce the retention of fingerprints on the surface of the body.
