Abstract
A wireless audio device, charging system, and method of charging a battery. The wireless audio device includes a communication module configured to enable the wireless audio device to communicate wirelessly and a battery. A charging interface is configured to establish a power transfer connection to the battery from a power source. A memory is configured to store paired history data indicating that the wireless audio device has been paired to an audio source upon the audio device being wirelessly paired. A controller is configured to detect the power transfer connection, determine a charge level of the battery, check the memory for the paired history data, and generate a control signal for selectively disabling the power transfer connection to prevent the charge level from exceeding a preset threshold unless the memory contains the paired history data.
