Hello ,I work with the sdk 12, I have a program to contoler the level of battery, it works, except that I recode 3870 mV (with USB) and when I measure the pin VDD I find 2.88. I do not know is what I made a code fault thanks

Do you use the SAADC? What is the gain and reference set to? And what code do you use to convert to mV?
Check the NRF_SAADC->CH[0].CONFIG register to verify that the gain is really set at 1/6
