A few design modifications are anticipated for the iPhone 15 series.
Compared to stainless steel, titanium is more resilient.
The release of the iPhone 15 is anticipated for the second half of 2023.

The rumoured iPhone 15—the device that will replace the iPhone 14—might include a new border style. Apple will allegedly take a significant design risk with the upcoming iPhone model, according to a recent leak. According to rumours, the iPhone 15 would not have a flat side bezel like the iPhone 14 line, but one that slopes backwards.

The Cupertino company might also switch out titanium for stainless steel with the iPhone 15. The Pro versions in the upcoming series could have titanium frames instead of stainless steel like the iPhone 15 and iPhone 15 Plus. Rumor has it that the iPhone 15 may feature a new border design.

In contrast to the iPhone 12, iPhone 13, and iPhone 14 models' straight edges, he asserts that the upcoming phone will have curved rear borders. Additionally, it is speculated that Apple would employ titanium for the iPhone 15, as opposed to earlier models, including the iPhone 14 Pro range, which have a stainless steel chassis.

Because titanium is more expensive than stainless steel, the premium iPhone 15 Pro and iPhone 15 Ultra models may include a titanium frame. The standard iPhone 15 and iPhone 15 Plus will reportedly have stainless steel frames.

It is projected that Apple's iPhone portfolio for 2023 will include the regular iPhone 15, iPhone 15 Pro, and iPhone 15 Pro Max versions. The iPhone 15 Pro and iPhone 15 Pro Max are anticipated to have Apple's forthcoming A17 Bionic CPU and 8GB of RAM. The non-Pro versions might utilise the A16 Bionic chip from this year.

Ming-Chi Kuo, Apple analyst of TF International Securities, believes that the iPhone 15 range's two primary selling points will be its button-free design and compatibility with USB type-C charging.

There are rumours that the premium iPhone 15 models do away with the physical volume and power buttons in favour of solid-state counterparts, which are similar to the home buttons on iPhone 7, iPhone 8, and iPhone SE smartphones. To simulate the sound of a click, they might be equipped with three Taptic Engine vibration motors.
