OtoZen can only record trips while your phone is powered on.

If your phone battery dies during a trip:

• The trip will be saved only up to the point where the phone turned off
• A battery error icon appears in your trip history
• Trips shorter than 0.1 miles may not appear in the app
• Connections may not receive the trip-end notification

To avoid incomplete trips, make sure your device has enough battery before driving.
