for the old batch 0903, the discharge current of RTC battery is too high so the RTC survive less than 2 days.
if you can, a DIY work will help (need some DIY solder skill and equipment):
1, take the battery + pin from PCB, use a heat resisting tape to insulate;
2, connect the battery +pin with the diode with a 220R resistor
that means add a resistor between the diode and battery, which will extend the RTC last time effectively.
<<of course, if you can't DIY, it is OK to send the the camera to our factory to repair>>
and some users feedback the last files of every driving is damaged, that is because a charging diode was burn/damaged from high input voltage for some reason.
please replace the SS14 diode with a new one, then the camera will work fine.
