| `battery_time_until_full`  | Number  | Estimated time in seconds until battery is fully charged (null if not charging) |
| `battery_time_until_empty` | Number  | Estimated time in seconds until battery is depleted                             |

## Origin System Information

| Variable                | Type   | Description                                                     |

| `origin`                | Object | Contains information about the Origin system version and kernel |
| `origin.version`        | String | The version number of Origin                                    |
| `origin.kernel.version` | String | The kernel version number                                       |
| `origin.kernel.type`    | String | The kernel type (e.g., "stable")                                |

## Examples

```javascript
// Display system information
log "Running on " + system_os + " using " + system_browser
log "Origin version: " + origin.version
log "Kernel: " + origin.kernel.name + " " + origin.kernel.version + " (" + origin.kernel.type + ")"

// Use the fps value for performance monitoring
if fps < 30 (
  log "Warning: Low performance detected"
)

// Use delta_time for frame-independent animations
position_x += speed * delta_time
```
