Abstract: A power saving apparatus and a method for a mobile terminal are provided. The method includes measuring a system load for a preset time during an application execution in a power saving mode, setting, when the measured system load exceeds a reference load level, a limit clock frequency as a maximum clock frequency for the power saving mode, measuring, in the power saving mode, the system load due to the application execution, performing, when the measured system load exceeds the reference load level, the application execution at the limit clock frequency, and performing, when the measured system load does not exceed the reference load level, the application execution at a system clock frequency corresponding to the measured system load, where performing the application execution at the limit clock frequency reduces a battery power consumption.
