Power Consumption Issue

[mayank-mpc]

IDF Ver - ESP-IDF v5.3.1
Devkit - ESP32 S3 N16
Other Peripherals - Nordic PPK2 and ESP-Prog

Goal - I want to achieve the power consumption of 240 uA using esp_light_sleep_start() function and 8 uA using esp_deep_sleep_start() function. I don't know why I am not able to achieve those results. At present when esp_light_sleep_start() is used I am getting around 1.8 mA and when esp_deep_sleep_start() is used I am getting around 860 uA.

Steps tried
- Tried disabling the unnecessary modules in the menuconfig which might cause this problems for example USB-JTAG-CONSOLE.
- Initialized and deinitialized Wi-Fi module and UART module.
- Reduced the main clock speed to 80 MHz from 160 MHz
- Referred to various other references as well but the solutions were not working for me.
- Also followed this URL https://docs.espressif.com/projects/esp ... dules.html connection for testing the power consumption

Link to references which I tried to follow

Requesting the community to help me in solving this problem.

Attaching code below

Code: Select all

#include <stdio.h>
#include "freertos/FreeRTOS.h"
#include "esp_sleep.h"
#include "esp_wifi.h"

void app_main(void)
{
    esp_sleep_enable_timer_wakeup(30 * 1000 * 1000);

    esp_light_sleep_start();
    while (1)
    {
        vTaskDelay(1);
    }
}

Here are the few changes which I did in the menuconfig
