Electronic devices and notification methods

Abstract

To accurately notify a user of battery exchange timing with a simple configuration.SOLUTION: An electronic device includes a battery, a load circuit that is supplied with power from the battery, and executes predetermined processing at predetermined operation timing, a voltage detection circuit that detects a voltage value of a voltage output from the battery, and a control circuit that is supplied with power from the battery and controls operation of the load circuit. The control circuit calculates an under-operation voltage value which is a voltage value at operation timing, based on a first voltage value which is a voltage value at a first timing previous to the operation timing by a predetermined time, a second voltage value which is a voltage value at a second timing before the operation timing and after a preset first time from the first timing, and a preset correction parameter, and outputs, on the basis of, the under-operation voltage value, alert information indicating that a battery exchange timing has come.SELECTED DRAWING: Figure 3
