  6. 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.

Battery Health no funciona con las baterías iFixit.

Cambié la batería de mi iPhone 6 por una batería iFixit y no se puede ver el porcentaje de batería máximo. Aparece “reparar“.

Con alguna aplicación de análisis de batería muestra 98%.

Under “Battery Health,” my iPhone SE says only “Service” and gives none of the information listed here.
