Abstract
The invention relates to power saving in portable terminals (100) with recording media (200). Conventionally, there is the problem that a battery (104) in the portable terminal (100) may become exhausted and as a result the original function of the terminal cannot be performed. To solve this problem, when the remaining battery capacity is low, the invention controls power supply (108) to the recording media (200) and clock supply (110) to a CPU (202) in the recording media (200) so as to reduce power supplied to the recording media (200)
