# peakPower

The system’s peak power requirements exceed the battery’s current capacity.

```
static var peakPower: AVCaptureDevice.SystemPressureState.Factors { get }
```

## Discussion

Devices with chemically aged batteries are less able to respond to rapid increases in total power usage (CPU and GPU usage, I/O, camera systems, radios, etc). When a device detects such conditions, the system may limit capture sperformance to prevent an unexpected device shutdown.
