Battery Charging System

A non-transitory machine-readable medium including instructions that, when executed by processing circuitry of an electronic device, cause the electronic device to perform operations comprising:

• selectively charging a battery of the electronic device according to a first charging mode or a second charging mode, wherein the first charging mode includes charging the battery uniformly using a first mode charge current,
• wherein the second charging mode includes charging the battery using at least a first charge phase and a second charge phase, wherein the battery is charged using charge current less than the first mode charge current during at least one of the first and second charge phases of the second charging mode, and
• wherein a start time of the first charge phase and an end time of the second charge phase are determined by the electronic device according to a specified idle time of the electrical device, the end time of the first charge phase is determined according to a first specified battery charge level, and the start time of the second charge phase is determined according to a difference between the first specified battery charge level and a second specified battery charge level.
