An electronic apparatus obtains, from a battery, information about remaining power in the battery; detects a connection with a power supply apparatus, performs control to supply power from the power supply apparatus instead of from the battery, in a case where the connection with the power supply apparatus is detected; and displays a warning related to the remaining power in the battery when the remaining power in the battery is less than or equal to a predetermined threshold, in a case where the electronic apparatus operates using the power from the battery. In a case where the connection with the power supply apparatus is detected, the electronic apparatus displays the warning related to the remaining power in the battery when the remaining power in the battery is less than or equal to a second threshold.

A system for controlling charging and discharging of a battery includes a charging and discharging switch configured to perform a switching operation for the charging and discharging of a battery. An analog front end (AFE) unit is configured to detect a voltage of the battery and to be stopped after transmitting a specific signal when detecting a voltage having a certain voltage parameter value or more.
