Battery Health is a section in your iPhone settings that tells you how healthy the battery is compared to when the phone was brand new. New iPhones obviously start with a brand new, 100% healthy battery. Over time, as the iPhone is used and various features are turned on and off, the overall health and performance of the battery will decrease. However, as long as the battery stays at 80% or more, Apple still considers this to be an optimal peak.

If you go back one screen (Settings > Battery), scroll down to view the battery performance since the last charge. It will tell you when the battery was last fully charged and what has eaten at that charge since then. You can see how much battery each app has used, with the worst offenders at the top.
