Abstract
A near field communication (NFC) antenna in a mobile device is used to wirelessly charge a battery in the mobile device by placing the mobile device on, or in very close proximity to, a charging station that emits an electromagnetic field. An induced current from the NFC antenna is detected that is above a predetermined threshold for longer than a predetermined duration. The induced current is used to charge the battery in the mobile device.
