ESP32-C6 power consumption: Arduino vs Zephyr vs ESP-IDF

Qoitech has published an analysis by developer Kevin Leon comparing power consumption across three development frameworks for the ESP32-C6—a modern microcontroller increasingly used in battery-powered edge scenarios where replacing the battery is impractical. The analysis found that your choice of software framework heavily dictates energy efficiency. ESP-IDF delivers the most stable, low-power performance out of the box. Arduino excels at active efficiency but requires careful coding to avoid hidden background consumption and stack instability. Zephyr RTOS is the most power-hungry of the three, trading energy efficiency for cross-platform portability. For developers deploying battery-powered edge devices, the analysis suggests choosing based on your priorities—stability, coding ease, or platform coverage.
