In a method for managing power consumption of a mobile storage device, the mobile storage device includes a power switch, a timer, and a universal serial bus (USB) port. The method detects whether the USB port has a data transmission signal from the electronic device. The method further drives the timer to determine a time period of how long the USB port has no data transmission signal from the electronic device, and determines whether the time period is equal to a predetermined time. In addition, the method controls the power switch to switch on when the USB port has the data transmission signal from the electronic device, and controls the power switch to switch off when the time period is equal to the predetermined time.
