user57976: I am using Nodemcu ESP8266. I want to know how much my ESP board consume the battery during sleep mode.
as the Mannual said it spend about micro-ampere, but my multi meter said it spend 10 mili-ampere, I cannot believe the result.
so please see My arrangement is right and give some advice

red line is for vin, black line is for GND.
black pin is COM, red pin is mA.
I set multimeter on 20mA, 200mA, it said it is 10mA.
when I change multimeter to 10mA, 1mA, microAmpere, number was overflowed.
I already connected to RST - D0, so It is properly sleep & wake up automatically. and here is my running code in the board
#include <ESP8266WiFi.h>
#include <WiFiClient.h> 
#include <ESP8266WebServer.h>
#include <EEPROM.h>

void setup() {

}

void loop() {
  // put your main code here, to run repeatedly:


ESP.deepSleep(60e6);

}


user63783: ESP.deepSleep(60e6, WAKE_RF_DEFAULT); Try this code, it should decrease it a bit.

user79943: The Board you are using contains an ESP-12F Module, along with other chips that make it easy/possible to connect to UART over USB and thus flash the chip. This USB-to-UART converter chip isn't related to the ESP-12F Module, so is unaffected when the ESP goes to sleep, so the converter continues to draw about 10mA. You can't do anything about this unless you desolder it, or use a pure ESP-12F Module.
