II. View the Battery Health:

Apple recommends you get a new battery, once the Battery Health reaches 80% or lower. When the Battery Health is 80% or lower, it is time for a new battery.

1. Go To: Settings
2. Tap: Battery
3. Tap: Battery Health
4. View: [the percentage]
5. Is it 80% or less?  If so, it is time for a new battery.

Try Force Restarting your iPhone. Save any information that need be. Then perform the restart.

Seems I misread you post.

All is Fine. Unfortunately, there is no way to know how, nor when, the Battery Health percentage dropped. Apple recommends you get a new battery, once the Battery Health reaches 80% or less. In fact, it can even increase in percentage. That is all just a guestimation on Apple's part.
