The charging management module 209 is configured to receive a charging input from the charger. The charger may be a wireless charger or a wired charger. In some embodiments of wired charging, the charging management module 209 may receive a charging input from the wired charger through the USB port 207. In some embodiments of wireless charging, the charging management module 209 may receive a wireless charging input through a wireless charging coil of the portable electronic device 200. When charging the battery 213, the charging management module 209 may further supply power to the portable electronic device 200 by using the power management module 211.
The power management module 211 is configured to connect to the battery 213, the charging management module 209, and the processor 201. The power management module 211 receives an input from the battery 213 and/or the charging management module 209, and supplies power to the processor 201, the internal memory 205, the external memory, the display 225, the camera 223, the wireless communications module 217, and the like. The power management module 211 may be further configured to monitor parameters such as a battery capacity, a battery cycle count, and a battery health status (electric leakage or impedance). In some other embodiments, the power management module 211 may alternatively be disposed in the processor 201. In some other embodiments, the power management module 211 and the charging management module 209 may alternatively be disposed in a same device.
