摘要： An electronic device including: a housing, a battery mounted within the housing, a power interface disposed to or within the housing and configured to receive power from an external power source wirelessly or through a wire, and a circuit configured to electrically connect the battery and the power interface. The circuit includes a first electrical path configured to supply a first part of a current supply from the power interface to the battery, and a second electrical path configured to supply a second part of the current supply from the power interface to the battery and connected to the battery in parallel to the first electrical path. The circuit is configured to selectively control the current supply to the battery via the second electrical path at least partially based on at least one of a charge level of the battery or a signal from a sensor disposed in the housing.
