iPhone Battery health showing 94%

Battery Health is an inexact figure that varies with usage. Yours is excellent. Keep in mind that the average Apple Battery lasts for about 2 years of normal use. When that figure reaches 80%, it will be time to make an appointment at the nearest Apple Store for Battery Replacement.

Maximum Capacity of 94% indicates that on average, your Phone is about 6 months old, since the battery declines at an average of about 1% a month.

If your phone is older than 6 months......(it likely is).....your battery is doing great. I wish mine was doing as well as yours.
