Here what we learned while we were designing the new MagSafe wallets.
While the new iPhone 12 / 13 / 14 series is compatible with MagSafe wallets, Apple states that the back of the iPhone doesn't have to be covered with any metal or magnetic materials except MagSafe. Although weak magnets are unlikely to damage the smartphone, there is a possibility that they may affect some important aspects. For example, magnets from materials other than those outlined in Apple's guidelines can create magnetic fields that may interfere with the rear-facing camera with optical image stabilization.
When choosing a MagSafe accessory, make sure that the manufacturer follows these guidelines and that the seller knows what the product is made of. Apple recommends working with manufacturers who produce magnets according to their strict guidelines, and we cooperate with one such manufacturer.
