Under Peak Performance Capability, it will tell you what your battery's health status is. Normal peak performance is what you're aiming for.
When it says your iPhone has experienced an expected shutdown the performance is throttled to prevent further shutdowns. This can be disabled to manually enable peak performance.
Once you disable performance management, you cannot enable it again. It is automatically enabled after an unexpected shutdown.
Once your battery falls below a specific threshold (typically 80%), you will be notified that your battery's health is significantly degraded.
