Mobile terminal and USB dedicated charger determining method thereof |
摘要 |
A method of determining a charger of a mobile terminal, and which includes receiving, via a controller of the mobile terminal, a connection signal indicating the charger is connected to the mobile terminal; setting, via the controller, a charging current of the charger for charging the mobile terminal and increasing the set charging current in predetermined current units; measuring, via the controller, an actual current received from the charger and applied to the mobile terminal; comparing, via the controller, the set charging current with the measured actual current; determining, via the controller, a charging sector of the charger when the set charging current is larger than the measured actual current for a first predetermined amount of time; and calculating a charging current capacity of the charger using the determined charging sector. |

1. A method of determining a charger of a mobile terminal, the method comprising:
receiving, via a controller of the mobile terminal, a connection signal indicating the charger is connected to the mobile terminal; setting, via the controller, a charging current of the charger for charging the mobile terminal and increasing the set charging current in predetermined current units; measuring, via the controller, an actual current received from the charger and applied to the mobile terminal; comparing, via the controller, the set charging current with the measured actual current; determining, via the controller, a charging sector of the charger when the set charging current is larger than the measured actual current for a first predetermined amount of time; and calculating, via the controller, a charging current capacity of the charger using the determined charging sector. |
