Electronic device management method, and electronic device management system and host electronic device using the method

An electronic device managing method, the method comprising:

• receiving information regarding remaining battery capacity from at least one client electronic device connected to a host electronic device;
• displaying, on a display unit of the host electronic device, the received information regarding the remaining battery capacity;
• determining, from the received information regarding the remaining battery capacity, if the remaining battery capacity of the at least one client electronic device is sufficient;
• and
• recharging, using a power supply of the host electronic device, a battery of the at least one client electronic device, according to a set condition.

An electronic device managing method, the method comprising:

• receiving a list of files from at least one client electronic device connected to a host electronic device;
• receiving, via an input unit of the host electronic device, an input signal for searching a file;
• determining whether a first client electronic device, of the at least one client electronic device, storing the file can reproduce the file;
• and
• instructing the first client electronic device storing the file to reproduce the file.

An electronic device managing system, the system comprising:

• at least one client electronic device;
• and
• a host electronic device, connected to the at least one client electronic device, the host electronic device to perform at least one of remaining battery capacity management, file storage state management, and file reproduction management of the at least one client electronic device, wherein the host electronic device comprises:
• a connecting interface to connect to the at least one client electronic device;
• a display unit to display at least one of information related to a remaining battery capacity, information related to a file storage state, and information related to a file reproduction;
• a power supply to recharge and supply electric power to at least one battery of the at least one client electronic device;
• and
• a controller to control at least one of the remaining battery capacity management, file storage state management, and file reproduction management of the at least one client electronic device,
• wherein:
• the remaining battery capacity management comprises determining the remaining battery capacity of the at least one client electronic device and determining a battery recharge order of priority according to the determined remaining battery capacity;
• the file storage state management comprises displaying, on the display unit, a file storage state of the at least one client electronic device, and moving, copying, and/or deleting files, stored in the at least one client electronic device, according to a storage input signal;
• and
• the file reproduction management comprises searching for a file, according to a search signal input to an input unit, and, if one of the at least one client electronic device comprises the searched file, reproducing the searched file in the one of the at least one client electronic device, according to a set condition.
