Abstract: An electronic device and a wearable electronic device are provided in implementations of the disclosure. The electronic device includes a housing frame, a button assembly, and a circuit assembly. The housing frame has an inner cavity and a first through hole. The first through hole communicates with the inner cavity and an external space outside the housing frame. The button assembly includes a first conductive member and a second conductive member. The first conductive member is connected to the housing frame and at least partially in the external space. The second conductive member is at least partially in the first through hole. The first conductive member elastically abuts against the second conductive member, so that the first conductive member is in electrical communication with the second conductive member. The circuit assembly is disposed in the inner cavity.

Abstract: The disclosure discloses a mobile terminal, a DC-charging power source adaptor, and a charging method, where the mobile terminal detects whether two communication pins of a USB interface thereof are shorted, and if an inserted external device is a power source adaptor, then the mobile terminal communicates with the power source adaptor, so that the mobile terminal identifies automatically the type of the externally connected charging device. Also a specialized rapid charging mode is designed for a DC-charging power adaptor, so that a battery being charged routinely is DC-charged at large current using charging voltage output by the DC-charging power source adaptor, and a volt value of the charging voltage is adjusted dynamically to the varying voltage of the battery core.
