The battery health drop percentage is not related to charge cycles. This is overall battery health based on charge capacity left and is determined and affected by several external and internal factors. iPhone batteries, like all rechargeable batteries, are consumable components that become less effective as they age. You should change out the battery once your Battery Health reaches below 80% which will take over 2 years to reach under normal usage. Until then enjoy your iPhone.
