Was the battery voltage divider in circuit before the ADC command was added and the first measurments taken?
No, the voltage divider circuit wasn`t there when i measured 42uA


Leave the code as is and disconnect the divider from the battery and see if that makes a difference.
It is going back to 42uA


R5, R9, and R10
= pulldown resistors for unused pins



Thank You for your help ...
