We'd recommend performing a battery test:
1) Take your Dash Cam inside and plug it into mains power or a computer using the Nextbase provided USB cable.
2) Remove the SD card and press the reset button on the underside of the dash cam. Then turn the Dash Cam on. Please turn Parking Mode off and turn Screen Saver off as these could interfere with the test results.
3) Let it charge for 2-3 hours whilst turned off.
4) Unplug the power cable, turn the Dash Cam on and time how long the Dash Cam stays on for. The time it takes for the battery to drain will help us identify the root cause
5) Please remember that after this test your Dash Cam will once again need charging as the battery will be flat.
If the battery lasts for less than 3 minutes, the battery may have reached the end of it's lifespan. If this is the case, please contact our Support Team and we can explain the options available.
