With a fully charged battery, the Toniebox can be actively used for up to 7 hours. The battery life will vary depending on factors such as the volume of playback. The louder the volume, the shorter the battery life.
When the battery is almost empty, the Toniebox LED will light up solid orange.
When the battery is completely empty, the Toniebox LED will flash red and you will hear a voice message letting you know the battery is empty.
