Abstract
Methods and systems for implementing wireless charging identification using a sensor are described. A device platform operating a device, such as a mobile electronic device, may be configured to determine that the device is in wireless communication with a charging surface by receiving and analyzing information from sensors. A battery or another entity associated with the device may receive a charge wirelessly from the charging surface through induction or another means. The device platform may determine if an orientation of the device relative to the charging surface has changed depending on the state of the charging process. In some examples, the device platform may use information from an accelerometer, gyroscope, or magnetometer to determine whether the device has moved. Based on whether the orientation of the device has changed relative to the charging surface, the device platform may be configured to provide feedback through one or more systems, such as audible notifications.
