Abstract
An electronic device is equipped with power generating means (unit), a secondary battery, a device, charging detection means (unit), battery voltage detection means (unit), and a time display control means (unit). The time display control means (unit) is equipped with an operation suspension portion, an operation resumption portion, a timer, a persistence display control portion and a timer updating portion. The timer updating portion updates the remaining time of the timer to the persistence time according to the detected voltage detected by the battery voltage detection means (unit) is longer than the remaining time, and operates the timer in operation as it is when the persistence time according to the detected voltage is equal to or less than the remaining time of the timer in operation.
