Wireless Charging & MagSafe

⚠️

Wireless chargers work with both phones, but magnetic snap varies.

  • Your MagSafe charger will charge the iPhone 11 Pro Max via Qi, but it won't magnetically snap on.
  • Only the iPhone 17 has built-in magnets for MagSafe accessories. The iPhone 11 Pro Max needs a magnetic case or ring adapter.

MagSafe cases are NOT cross-compatible between these devices — the case body is shaped to each phone, even though the internal magnet ring may be the same.
