Why sleep mode current is same in all the sleep modes of Nucleo-L4R5ZI-P?

[Brajp.1]

I am using Nucleo-L4R5ZI-P board, I have flashed sleep mode selection sample code to check power consumption of all the modes, but in all the modes I am getting around 156uA.

I have also tried by disabling debug mode but the result is same.

How can I achieve same current consumption mentioned in datasheet.

Hello

Vbat measurement probe , backup battery charging resistor (VBE bit in the PWR_CR4 register.) TempSensor probe must be disabled.

Connections with STLink also (SW_debug ,PB3-Trace, Bypassed-HSE, serial port ) must be set to analog mode

If Hse is Bypassed from MCO of STLink, use as clock an internal oscillator

When put MCU to shutdown, stby, stop, VDD_1.2 or VDD12 pin must left unconnected from SMPS (page 189 of RM0432)
