I have the same issue with ttgo LORA32 (V2.1 1.6). Device starts in "ON" power mode and goes down power saving chain quickly. Battery is not attached if that matters. This happens after I connect the USB and reset the board.

I've debugged a stuff a little bit, here are the battery voltage readings (battery is not connected):

getBattVoltage() = 3641.601562 getBattVoltage() = 3641.601562 getBattVoltage() = 3635.156250 getBattVoltage() = 3615.820312

Does that mean I have a faulty board?
