Current consumption and state of GPIO in StandBy mode?

Question asked by vu.andy on Nov 11, 2016
For the STM32F0 device, in the standby mode after executing the function HAL_PWR_EnterSTANDBYMode(), will all the GPIO pins (except for the wakup pin and RTC tamper ...) are put in highZ mode?  Or is it something I have to explicitly do in the codes?

Also, assuming all the GPIO pins are in highZ mode, based on the datasheet, the current consumption for the following are in worse case:
Idd = 3.1uA
Idda = 4.6uA
RTC = 2.8uA
Are these accurate?  Are there any other source of current I should take into account?
Thanks.
