The battery in the OOONO CO-DRIVER NO1 typically lasts around 10-12 months. However, battery life naturally depends on how often the device is used.
In general, battery performance varies with temperature. Consequently, in case of low external temperatures, the battery performance may vary. This may result in issues with battery level read-out, firmware update and shorter battery life. However, once the car warms up, the product returns to full functionality.
