Scenario Charging Protection
No Case Optimal (15W) Minimal; leaves the phone exposed to damage
Non-MagSafe Case Moderately reduced efficiency (potential drop of up to 20% in some cases) Provides basic physical protection but might compromise charging speed and magnetic alignment
MagSafe-Compatible Case Designed to maintain full charging power (15W) with minimal interference Offers excellent protection along with seamless integration with other MagSafe accessories
