To do that, the Adafruit Feather docs say you should read from pin A9: https://learn.adafruit.com/adafruit-feather-32u4-basic-proto/power-management#measuring-battery-4-9. (See also https://learn.adafruit.com/adafruit-feather-32u4-bluefruit-le/pinouts#logic-pins-2-9.) I'm not sure why, but analogRead(9); doesn't read the correct pin.
