When I ran my power consumption tests using test firmware v1.0_1105 and my A139 Pro 3CH test unit, I definitely found the IR camera consumed more power than the rear camera. That's with the IR LED setting set to the default of "On". I found that the parking mode power draw was between 73 mA (0.92 Watts) and 86 mA (1.08 Watts) higher when using the IR camera. The same general power draw gap was observed in normal recording mode as well. My time estimate for "2CH, Rear" was very close to your actual test findings. My time estimate for the "2CH, IR" is far lower than your timed test. I'm wondering if the "Auto" mode for the IR LEDs left the IR LEDs off during a portion or all of your time test when there was enough ambient light in your test area(? depends on how you ran your test - just a guess on my part). That's why I left the setting at the default of "On" for the "2CH, IR" and "3CH" power consumption tests.
