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?
Ok, then we've confirmed that the config is setup with gain = 1/6, and it should have an input range of 3.6V. Could you try another input, one of the AIN0 - AIN8? Maybe one that is connected to ground? For example NRF_SAADC->CH[0].PSELP = 0x1 or something similar. I want to see that the output value changes.
