The Cycle Count is a number that refers to how much the battery is used. A single load cycle is the cumulative usage of 100% of the battery’s capacity. For example, discharging to 50%, charging to full, then discharging to 50% the next day will equal 1 load cycle.
Current: The number of load cycles that your battery has completed.
Factory: The number of load cycles for which the battery was designed. Apple declares that the above percentage should be 80% or greater until the current load cycle count reaches this number.
Percent of Lifespan: Expressed as a percentage, the number of load cycles your battery has completed compared to the maximum load cycles the battery was designed to achieve.
