A method and apparatus provides charging information regarding devices such as a portable terminal with a solar cell. The solar cell charges the battery of the portable terminal with the highest charging efficiency at an optimal charging angle. The optimal charging angle is determined according to the location information regarding the portable terminal and time information. When the solar cell performs a charging process with the highest charging efficiency, the portable terminal provides a user with an average charging efficiency and the help containing a user's manual of the solar cell. The average charging efficiency is determined according to environmental conditions, such as temperature, humidity, weather conditions, etc. |
