## List of exported metrics:
TODO: add grafana dashboard json here
`android_battery_charge_ratio` - Current battery charge
`android_system_info{manufacturer, model, os_release, cpu_core_count}` - Information about Android system
`android_uptime_seconds` - Phone uptime in seconds
`android_cpu_active_seconds{core}` - Active CPU time in seconds since last time system booted
`android_cpu_total_seconds{core}` - Total CPU time in seconds since last time system booted
`android_system_temperature_celsius{where}` - Temperature on the device
