Der iPhone 12 brachte flache Kanten zurück – eine Anspielung auf das Design des iPhone 4 – und debütierte MagSafe, Apple’s magnetic charging system integrated beneath the glass.

The back cover became more than protection; it was a functional platform for accessories and efficient power transfer.
Mit dem Keramikschild Glas, Apple also enhanced drop resistance by up to 4x.

Refined Aesthetics (iPhone 13 Und 14 Serie)

Apple continued refining the glass era.

• Diagonal cameras gave the iPhone 13 its signature look.
• New colors like Pink, Midnight, and Starlight showcased Apple’s mastery of pigments and transparency.

Der iPhone 14 further improved repairability — a subtle but critical design shift that allowed the back glass to be replaced more easily.

The Era of Color-Infused Glass (iPhone 15 Serie)
