Voltage measure problem

I have battery connected to PIN35 via voltage divider. When I have esp32 (lolin32 lite) connected to computer I have no problem with measurement of battery voltage. But when esp32 is running on battery, measured voltage is different and it doesn't make sense. What is the problem?
