+### Battery display mode — 🟢 [FreeTRX]
+The battery level in the top status bar can be shown three ways, cycled with
+◀/▶ at **Menu → Options → Display Options → Battery**:
+
+- **%** — remaining charge as a percentage.
+- **V** — the measured battery voltage.
+- **Bars** — a battery-shaped icon with up to **four segments**, each worth
+  **25 %** of charge. The fill blinks when the battery is low.
+
+The **%** and **V** options are inherited from OpenGD77; **Bars** is the new
+addition. In every mode the low-battery warning still blinks the reading.
