The phone’s overall footprint is compact and well-balanced, making one-handed use feasible for many. On the other side, Apple’s iPhone 15 maintains its signature elegant design language, featuring aerospace-grade aluminum and a Ceramic Shield front cover, which Apple claims is tougher than any smartphone glass. The edges are slightly contoured, providing a comfortable grip that many users find appealing. Its Super Retina XDR display is vibrant and color-accurate, with a peak HDR brightness of 1600 nits and typical brightness of 1000 nits. While the iPhone 15’s display is undoubtedly gorgeous, it retains a standard 60Hz refresh rate. This might be a noticeable difference for users accustomed to higher refresh rates on other devices, leading to a less fluid visual experience during fast-paced content or scrolling. However, for everyday tasks and general media consumption, the iPhone 15's display remains excellent. A significant design change for the iPhone 15 is the adoption of the Dynamic Island, replacing the traditional notch.
