@BLUETTI_CARE: As I said, the battery was new when I did one set of those tests, and a few months old (broken-in but still new) for the other set. Please read the post…
I would expect my vehicles gas mileage to perform within in specs with a reasonable variance due to differing user scenarios. “What you expect” the idle power consumption to be is only your expectation unless a mfg. specifications specifically state what the idle consumption is in their published specifications. What specific claim regarding Bluetti’s efficiency are you stating is not being met? I have an original AC200 that is two years old and it has always had high idle power consumption and it has always been stated to have high idle power consumption and it works just fine. I understand its limitations and if I want to dig a small hole, I use a small shovel. If I want to dig a bit hole, I use a bigger shovel but I do not complain about the additional energy required with using a bigger shovel because I understand that bigger means more operational energy. By the way, I have several smaller “Bluetti Shovels” that I use when I need lower idle consumption. All portable power stations consume power at idle regardless of size.

That’s great; but not everyone has the luxury to purchase multiple units. You can feel free to purchase them for us 
and then I won’t complain.
Of course, my issue isn’t that there is self-consumption. I was very clear that the issue is that the actual value is about 2x what Bluetti says. If their specs matched reality, then we’ll know what to expect when getting it, and all would be well.
I’m not sure I understand why you seem to think it unreasonable for someone to expect that what the item they purchase behaves as the manufacturer says it does…
I have also an issue with the update. I was happy with the old bms version and all numbers seem to be correct. 12v lights, even my phone charging had a watt value accordingly. But I was notified by the app to make an update on the firmware and bms, which I did. From then on, all my power consumption is incorrect. Phone charging says 0 w… etc. Today I had my diesel heater + my TV and Android box + 2 12v lights and the maxxfan led on + my fridge that takes about 40 to 50w, my Ac200max was giving me only 40w of consumption. Also, When charging I noticed that the numbers were too quick for the 400w charging, it went from 75% to 90% in minutes. I already “reset” the power station once and the problem persists. I am at this moment “resetting” the machine again and hoping it gives me better results. ARM v4008,05 - DSP v4005,08 - BMS v1017,03.
