+Full Companion firmware accepts the command from its local USB terminal and exposes the same setting in WebConfig. On ESP32, it lowers the CPU clock to 80 MHz, enables idle yielding, and enables the configured GPS duty cycle. USB, BLE, and WiFi remain available. `powersaving off` restores the board's normal CPU clock and disables the GPS duty cycle. This device setting is separate from LoRa RXPS (`radio.rxps`) and WiFi modem power save (`wifi.powersave`).
