Wireless Charging & MagSafe
Wireless chargers work with both phones, but magnetic snap varies.
- Your MagSafe charger will charge the Galaxy S25 Ultra via Qi2, but it won't magnetically snap on without a magnetic case.
- The Galaxy S25 Ultra supports Qi2 but has no built-in magnets — magnetic accessories won't snap on without a magnetic case. The iPhone 15 Plus has built-in magnets.

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.
