ESP32 ADC measurment with variable input voltage?

[jim-p]

@orangedays22

How reliable to do you think it is to generate the 1.1V inside the ESP32 when the input voltage is varying between, 3.0 and 3.6V?

Very

I have found this thread here which states that some users get very different ADC voltages depending on the input voltage:

It seems that the OP was somewhat confused about the ADC and could not prove his claims.
