Hi...I am using STM32WB5MMG MCU..to optimize the power consumption I am using HAL_PWREx_EnterSTOP2Mode() to put the controller in sleep mode.. But after power cycling the board multiple times the power consumption increases and not stable always...What can be done to achieve the lowest power and it should not have any fluctuation in power once the device is reset for multiple time....
