How Battery Health Works
iPhone battery health is measured in two key ways:

Apple considers a battery healthy when it has:
- Less than 30% capacity loss
- Less than 500 full charge cycles
Note: Battery health can vary between iPhone models. The calculator provides a general assessment that may not be 100% accurate for all devices.
