• Deep Sleep: The firmware utilizes an aggressive but effective deep sleep mode. If left unconnected for a period (approx. 10–15 minutes), the speaker shuts down to preserve the massive battery capacity these units are known for.
• Battery Calibration: The battery indicator logic is accurate. The firmware provides honest readouts of remaining battery life rather than the common "100% to dead in 5 minutes" issue seen in cheaper speakers.
• Pass-Through Charging: The firmware allows for pass-through charging (playing while plugged in) without overheating or introducing line noise, a sign of well-written power regulation code.
