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 13 Pro Max has built-in magnets.
