What does "Battery Cycle Count
So if your battery cycle count is 3 that means 3 full charge cycles. A full charge cycle is 0-100%, or any combination that adds up to 100%, such as 50% to 100% twice, 25% to 50% four times, etc. As one example, if you charge the phone overnight, every night (and that is what you should do; it is a best practice), it starts the day at 100%.
