Abstract
A control method of power supply for a portable electronic device is disclosed. The portable electronic device includes a power supply module and a control circuit, and the power supply module is configured to provide electric power to the portable electronic device. The control method of power supply includes detecting, by the control circuit, a system status of the portable electronic device or a module status of the power supply module; and adjusting, by the control circuit, a reserved battery capacity of a main battery of the power supply module according to the system status of the portable electronic device or the module status of the power supply module.
Claims18
A power supply control method for a portable electronic device including a power supply module and a control circuit, the power supply module being configured to provide power to the portable electronic device, the power supply control method comprising:
- detecting, by the control circuit, a system status of the portable electronic device or a module status of the power supply module;
- and
- adjusting, by the control circuit, a reserved battery capacity of a main battery of the power supply module according to the system status of the portable electronic device or the module status of the power supply module;
- increasing, by the control circuit, the reserved battery capacity when a system leakage current of the portable electronic device is larger than a threshold.
A portable electronic device, comprising:
- a power supply module, including a main battery configured to provide power to the portable electronic device;
- and
- a control circuit, coupled to the power supply module, configured to detect a system status of the electronic device or a module status of the power supply module, and to adjust a reserved battery capacity of the main battery of the power supply module according to the system status of the portable electronic device or the module status of the power supply module;
- wherein the control circuit is configured to increase the reserved battery capacity when a system leakage current of the portable electronic device is larger than a threshold.
