TTGO LoRa32 V2.0 battery level

Battery voltage measurement works [20201230_152200] I had to add a 20k potentiometer, 10nf capacitor and adjust the indication (the error was -0.68V and it drifted).[20201230_151648] But now lora32 never sleeps as if it were connected to USB all the time. Even when I disconnect IO35. [20201230_154931]
