BAT_ADC (GPIO4) sits between two 100k resistors on the switched supply rail, so it reads the cell on battery and ~4.4 V on USB; above 4.25 V is reported as USB power. On battery the caption shows a glyph + percentage from a LiPo OCV table; the menu shows voltage and source. Menu lists now wrap at both ends.
