1. A case for an electronic device having a coil for wireless charging, wherein the coil is disposed in the electronic device and has an inner boundary and an outer boundary, the case comprising:
a protective cover configured to cover the electronic device such that the electronic device is at least partially received in the protective cover; and
at least one metal plate attached to the protective cover,
wherein the at least one metal plate is positioned to allow magnetic waves to pass through an area formed by the inner boundary of the coil, and
wherein the at least one metal plate is positioned not to overlap with an orthographic parallel projection of an area formed by the inner boundary of the coil when the electronic device is at least partially received in the protective cover.
