How to check your iPhone battery health
Ever since iOS 11.3, Apple added a new feature under the Battery tab called Battery Health. This particular section lets you see the percentage of your battery and performance capability in regard to how your battery health is doing.
Once your maximum capacity drops below 60%, it will no longer be at peak capacity performance. Your device will then be throttled.
This is when Apple purposefully slows down your phone so that it can still function with the weak battery.
