Low Power Mode in STM32L152

hamed ad

Hi,
I am using the below function to enter low power mode in STM32L152, but yet the current consumption of MCU is about 4 mA. is there other configurations?

RCC_APB1PeriphClockCmd(RCC_APB1Periph_PWR,ENABLE);
PWR_EnterLowPowerRunMode(ENABLE);

    Thanks for your points.
    Indeed to measure the current of MCU I have not soldered any other parts on my board.
    As you said I could not use Discovery board because its consumption is about 60mA with all parts on it.
    it seems any change in MSI frequency does not affect the power consumption of my board. Any Idea t go step by step to make power consumption low?
