Tech Tip: Battery Cycles Help Track Battery Health

PR_NT13UBbatteryWe’ve all experienced the frustration of a battery that has begun to reach the end of its lifespan and simply won’t hold a full charge. Batteries possess a limited amount of charge cycles, which is the equivalent of one complete drain of the battery’s power before a recharge.

Each Apple device’s battery has a particular number of cycles. A cycle is the measure of the number of times that 100% of the battery’s charge was added back. For example, two recharges from 50% to 100% is one cycle, 4 charges from 75% to 100% is one cycle.
