This can only happen if the motorcycle battery is also empty, or the connection has been disconnected from the motorcycle battery and the BikerSOS GPS-Tracker can no longer be charged.
In the app in the menu item "Tracker" the message appears:
"GPS-Tracker battery almost empty"
You will receive the message as a push message on your smartphone:
"GPS tracker battery almost empty"
