Bluetooth Battery Meter is a Gnome Extension featuring indicator icons in system tray, serving as meter for Bluetooth device battery levels and providing detailed battery levels via icon/text in the Bluetooth quick settings menu.

Important Notes

  • Certain Bluetooth devices report battery levels in different increments.
  • One would expect a continuous discharge reading like 100, 99, 98, 97… down to 0.
  • However manufacturers often design devices to report in specific increments.
  • Some devices may report battery levels in increments of 5 (e.g., 100, 95, 90, 85… to 0)
  • Some devices may report battery levels in increments of 10 (e.g., 100, 90, 80, 70… to 0)
  • Some devices may report battery levels in increments of 20 (e.g., 100, 80, 60, 40… to 0)
  • For Quick settings percentage displayed in text (when enabled), might observe battery level stuck at a percentage example 100% for a while and later suddenly drop down to 80%, if designed for increment of 20%.
