The Battery Life Gap


ESP32 is not a low-power chip. It is a high-performance WiFi chip that can enter a low-power state.

The distinction matters.

When the ESP32 is awake, it draws 80-240mA depending on radio activity. In deep sleep, the datasheet promises 10μA.

But 10μA is the number for the ESP32 chip alone, with no peripherals, no voltage...
