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.

Abstract: The disclosed embodiments provide a system that manages use of a battery corresponding to a high-voltage lithium-polymer battery in a portable electronic device. During operation, the system monitors a cycle number of the battery during use of the battery with the portable electronic device, wherein the cycle number corresponds to a number of charge-discharge cycles of the battery. If the cycle number exceeds one or more cycle number thresholds, the system modifies a charging technique for the battery to manage swelling in the battery and use of the battery with the portable electronic device.
