Your ESP32 Project Should Run for Months, Not Days

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 regulator, no sensors, no USB-to-serial chip, no pull-up resistors, and powered directly from a perfectly clean 3.3V supply. Your actual circuit looks nothi
