Phone cases with a MagSafe magnet remain firmly attached around your iPhone 12 series and newer. You can easily click this case on your device with the magnet. A MagSafe case enhances the effect of the magnet, so you can be sure the wireless charger stays in the right place. Other accessories, such as a card holder, also work well with a MagSafe case. Normal cases without a MagSafe magnet are too thick sometimes, so the accessories won't stick well. Of course, the MagSafe cases with magnet also protect from damage. Only the iPhone 12 series has a MagSafe magnet.
