Tested the custom firmware with default Wifi On:There does not seem to be much difference in power consumption between parked mode and recording mode.
Both hover around 5.12v to 5.14v and 0.30A to 0.34A. It seems to be mostly around 5.12V/0.32A.
(Using a USB voltage and amp tester between the charger and the dashcam)
Thank you for the test, maybe the developer (@estore009 ) looking into ... and take advantage of parking mode on battery lifeTested the custom firmware with default Wifi On:
While recording: 5.14V / 0.34A = 1.75W
While in parking mode: 5.12V / 0.32A = 1.64W
Tested the custom firmware with default Wifi Off:
While recording: 5.12V / 0.25A = 1.28W
While in parking mode: 5.11V / 0.24A =1.23W
"Parking mode" does not seem to do much in terms of saving the battery life of the vehicle. Probably only good for the SD card as it writes less ...
The above numbers are very optimistic as the amperage and voltage differs from second to second. Could probably be off by 0.05W or so
that would be easy to do if it supported 3 wire power supply, don't think it does thoughThis should be rather easy to do:
- when the camera detects no power on the yellow wire just shut down wifi to conserver power and start g-sensor mode
- when the camera detects power on the yellow wire - turn on wifi back on and start recording
