STM32L0 in lower power stop mode with RTC and RAM retention consuming more current

[ASequ.1]

As mentioned in the datasheet of STM32L053 with Stop mode + RTC + 8-Kbyte RAM, current consumption is 0.8 μA. I have the STM32L053 Discovery board and to test the stop mode on it I'm using example code provided by ST. Path of the example code: ~\STM32Cube\Repository\STM32Cube_FW_L0_V1.1.0\Projects\STM32L053C8-Discovery\Examples\PWR\PWR_STOP_RTC

Both example code v1.1.0 (Old) and v1.12.0 (latest) are the same.

With the example code the current consumption is ~180μA on the discovery board. I'm measuring the current at Idd (JP4) pin 1 and 2. Current consumed is much higher than mentioned the datasheet.

Is there any more step to be followed to reduce the current? Please suggest

Do you use the debugger? Then don't.

Set DBG_CR to zero before entering low-power mode and disconnect the debugger physically.
