MagSafe is Apple's magnetic alignment and attachment system, built into iPhone 12 and all later iPhone models. At its core is a precisely arranged ring of magnets embedded in the back of the phone that snaps instantly to any MagSafe-compatible accessory — cases, wallets, mounts, and battery packs — with a satisfying, tactile click into place.

The magnet array is engineered to a precise specification so that compatible accessories self-align on contact, eliminating the need for clips, adhesives, rails, or cables to hold them in position. The connection is strong enough to keep accessories firmly in place during normal daily use — in a pocket, bag, or held in hand — while still releasing cleanly with a deliberate pull. There are no moving parts, no latching mechanisms, and no wear components.

MagSafe cases pass the full magnetic field through to the phone, meaning accessories attach with the same strength and precision whether the phone is bare or cased. This creates a layered, modular accessory system where a single case unlocks compatibility with the entire ecosystem of MagSafe-certified accessories from Apple and third-party manufacturers.
