Abstract
A technology for charging the battery of a terminal device with efficiency. In a wireless game controller, a charge control unit supplies electric power from an external power supply to a battery. A communication management unit receives a drive request signal to a vibrating motor. A motor control unit supplies a drive current to the vibrating motor in accordance with the drive request signal. The charge control unit performs charge control for the battery in a first mode when the communication management unit does not receive the drive request signal, and performs charge control for the battery in a second mode when the communication management unit does receive the drive request signal. The charge control unit performs the charge control for the battery in the first mode using a charging current higher than that in the second mode.
