Finally, the iPhone 15 is out. It has a design that feels just right. The aerospace-grade aluminum frame is highly durable, and the new contoured edges feel even better in your hand. The innovative new design features back glass with color infused throughout the material. A custom dual ion exchange process for the glass and an aerospace-grade aluminum enclosure help make the iPhone 15 incredibly durable. Using chemistry, Apple perfected the creation of color. Superfine metallic ions embed color into the glass — with a unique formulation for each color. Then, the glass is polished with nanocrystalline particles and etched to create a textured matte finish. The phone measures 147.6 x 71.6 x 7.8 mm and weighs 171g. Moreover, 75% recycled aluminum is in the enclosure and available in Black, Blue, Green, Yellow, and Pink.
