Document Type and Number:
WIPO Patent Application WO/2020/231099
Kind Code:
A1
Abstract:
An electronic device includes a first battery, a second battery, a power management integrated circuit, a memory, and a processor. The memory is configured to store information on a first full-charging voltage value of the first battery and a second full-charging voltage value of the second battery. The processor is configured to detect whether the electronic device is connected to an external electronic device for supplying power to the first battery or the second battery. When the first full-charging voltage value is higher than the second full-charging voltage value the processor is configured to, electrically connect the first battery to the power management integrated circuit and electrically disconnect the second battery from the power management integrated circuit. The processor is further configured to charge the first battery electrically connected to the power management integrated circuit based on power obtained from the external electronic device.
