It takes around an hour to recharge an iPhone 12 from zero to 50 percent using the MagSafe Charger, which is twice time it takes to charge by using USB-C to Lightning adapter and a 20W+ USB-C charger adapter.
Important!
- Apple warns that while using the MagSafe Charger, it may leave a mark on the Leather Cases designed for MagSafe iPhones. It can also harm silicone cases.
- Credit cards, security badges, passports, or key fobs should not be placed between the iPhone and the MagSafe Charger because magnetic strips and RFID chips might be destroyed.
