Rumors are spreading that the iPhone 15 may feature a titanium chassis and curved trailing edges

News Summary:

  • According to Twitter user @ShrimpApplePro, the rear edges of the iPhone 15 will be rounded to create a new bezel similar to the bottom borders on the casing of Apple’s latest 14-inch and 16-inch MacBook Pro models.

  • According to a new rumor, Apple’s 2023 iPhone will have a titanium body with curved rear edges to replace the existing square design.

For reference, the iPhone 14 models have a flat design with rounded edges that harkens back to the iPhone 4. The last model with curved edges was the iPhone 11.

This is not the first time we have heard rumors that Apple will release a titanium iPhone. Earlier this year, iPhone 14 rumors suggested that the iPhone 14 Pro and iPhone 14 Pro Max would have titanium alloy chassis. However, that didn’t play out: All iPhone 14 models have chassis made of aluminum and stainless steel.

Despite the switch to titanium material, the iPhone 15 “will still have a glass back,” claims the leaker, who has provided accurate information in the past, although @ShrimpApplePro cautions that the information is “still very early to take it as it is.”

However, Apple recently researched the viability of titanium enclosures for its products, including patents regarding machined titanium with unique properties for future MacBooks, iPads, and iPhones.

Compared to stainless steel, titanium has relatively high hardness, making it more resistant to scratches, and its rigidity makes it durable enough to withstand bending.

However, titanium’s strength also makes it difficult to etch, so Apple has developed a blasting, etching, and chemical process that can give titanium housings a high-gloss finish for a more beautiful appearance.

Apple has also been researching the use of thin oxide layers on the surface that can reduce oily fingerprints. If the latest reports are correct, it would be the first time Apple has used titanium in iPhones and iPads. The company has used titanium as the casing material for recent Apple Watch models such as the Apple Watch Ultra, and the physical Apple Card is made of titanium. Yet the latest iPhones and iPads are made of stainless steel and aluminum.

According to Bloomberg’s Mark Gurman, Apple could replace the “Pro Max” version of the iPhone 15 with a new “Ultra” model, along with naming the Apple Watch Ultra to indicate a premium product. Whether the titanium casing rumor relates to a specific iPhone 15 model, however, is not known. Whether the titanium casing rumor relates to one particular iPhone 15 model, however, is not known.
