Magnetic self-aligning coil centering for wireless charging

A portable device, comprising:

• a second induction coil configured to receive power wirelessly from a charging device having a first induction coil;
• a second charging surface including a second coil charging area defined by the second induction coil;
• and
• a third magnet disposed at the second charging surface, wherein
• when the portable device is in proximity of the charging device, the third magnet creates a first magnetic attraction force with a first pole of a first magnet having the first pole and a second pole disposed at a first charging surface of the charging device, and the third magnet creates a first magnetic repulsion force with a second pole of a second magnet having a first pole and the second pole disposed at the first charging surface of the charging device, wherein
• when the second charging surface of the portable device is placed adjacent to the first charging surface of the charging device, the first magnetic attraction force and the first magnetic repulsion force cause a first coil charging area of the first charging surface and the second coil charging area to be aligned, and wherein the first coil charging area defined by the first induction coil,
• wherein the first magnetic attraction force provides an anti-tip magnetic attraction force when the portable device is adjacent to the first charging surface and a touch force is applied to a display portion of the portable device when the display portion is in an open position.

A method, comprising:

• in a charging device including:
• a first induction coil configured to transmit power wirelessly to a portable device having a second induction coil;
• a first charging surface including a first coil charging area defined by the first induction coil;
• a first magnet having a first pole and a second pole and disposed at the first charging surface;
• and
• a second magnet having a first pole and a second pole and disposed at the first charging surface,
• creating, by the first pole of the first magnet, a first magnetic attraction force with a third magnet disposed at a second charging surface of the portable device, when the portable device is in proximity of the charging device;
• creating, by the second pole of the second magnet, a first magnetic repulsion force with the third magnet;
• and
• causing, by the first magnetic attraction force and the first magnetic repulsion force, the first coil charging area and a second coil charging area of the second charging surface to be aligned, when the second charging surface of the portable device is placed adjacent to the first charging surface of the charging device, wherein the second coil charging area defined by the second induction coil,
• wherein the first magnetic attraction force provides an anti-tip magnetic attraction force when the portable device is adjacent to the first charging surface and a touch force is applied to a display portion of the portable device when the display portion is in an open position.
