An electronic device includes: a communication section to wirelessly communicate with an external device; a first section to make the communication section establish a wireless connection with the external device; a detective section to detect whether the electronic device is in a used condition or an unused condition; a second section to shift to a power-saving mode when the unused condition is detected for a while; and a third section to cancel the power-saving mode when the used condition is detected during the power-saving mode, wherein the second section cuts off the connection if the connection is still alive when shifting to the power-saving mode; and the third section changes a connection processing for making the first section establish the connection after the power-saving mode was canceled, based on a connecting condition from a time of detecting the last used condition to a time of shifting to the power-saving mode.
