1. An operation method of a user system which includes a first device and a second device, which share a shared voltage, and a power management integrated circuit (PMIC) configured to generate the shared voltage, the method comprising:
performing a first operation of the first device;
predicting whether a second operation of the second device is to be performed while the first device performs the first operation, based on an operation profile; and
when it is predicted that the second operation of the second device is to be performed while the first device performs the first operation, changing a power mode of the PMIC from a first power mode to a second power mode, before the second device performs the second operation,
wherein the PMIC is configured to generate the shared voltage based on the first power mode or the second power mode.
