    Do you have an LSE crystal, is it ticking, does it tick during power down?

    Do you have VBAT powered?

    What STM32? What board?

    Ohh sorry.. I should give you more information of course..Not board it is our own device with STM32F205RCT6,  external LSE CRY= 32768 KHz

     3.3V VBAT  always connected. Actually I wonder  if a software mistake exist like Enabling a Enabled RTC or Starting it again at every power-on.. Can you explain some functions in lines on picture that I upload.In library explanations are not enough..
