Wireless Charging & MagSafe
Wireless chargers work with both phones, but magnetic snap varies.
- Your MagSafe charger will charge the Galaxy S24 Ultra via Qi, but it won't magnetically snap on.
- Only the iPhone 16 Pro Max has built-in magnets for MagSafe accessories. The Galaxy S24 Ultra needs a magnetic case or ring adapter.
