Abstract: An electronic device. The electronic device may include a battery, and a charging system in electronic communication with the battery. The charging system may be configured to charge at least a partially-depleted battery to a threshold charge value, discontinue the charging in response to the battery being charged to the threshold charge value, and monitor the function of the electronic device to detect at least one of an anticipated event, and an unanticipated event of the electronic device. Additionally the charging system may be configured to recharge the battery in response to detecting one of: the anticipated event occurring a predetermined time subsequent to the recharging of the battery, or the unanticipated event occurring immediately before the recharging of the battery.
