If the Maximum Capacity is at 100%, it means the battery is in good health and can hold its full charge. However, over time, the Maximum Capacity may decrease due to regular use, temperature, and other factors.

If the Maximum Capacity is below 80%, it means the battery’s health has deteriorated, and it may need to be replaced. Apple recommends replacing the battery when the Maximum Capacity falls below 80%.

It is important to note that the Maximum Capacity is not the same as the battery’s performance. A battery may have a high Maximum Capacity but still experience performance issues due to other factors such as background app activity, network signal strength, and more.

In summary, the Maximum Capacity metric is a useful indicator of the iPhone battery’s health, but it should not be the only factor considered when evaluating battery performance.

Significance of Peak Performance Capability

Peak performance capability is an essential feature that determines the performance of an iPhone. It refers to the maximum performance that an iPhone can achieve under normal conditions. The peak performance capability of an iPhone is dependent on the battery’s health and capacity.

The Battery Health screen on an iPhone includes information on the maximum battery capacity and peak performance capability. Maximum battery capacity measures the device battery capacity relative to when it was new. A battery will have a lower capacity as the battery chemically ages, which may result in fewer hours of usage between charges.

If an iPhone’s battery has degraded significantly, it may affect the device’s peak performance capability. Apple introduced a feature in iOS 11.3 that manages the peak performance capability of an iPhone to prevent unexpected shutdowns. If the battery is unable to deliver the required power to the device, the iPhone will automatically reduce its performance to prevent the device from shutting down unexpectedly.

Users can check their iPhone’s peak performance capability by going to Settings > Battery > Battery Health. If the peak performance capability is below 80%, the user may experience reduced performance and unexpected shutdowns. In such cases, it is recommended to replace the battery to restore the device’s performance.
