I think that is a result of this being their first entry into the ARM market. IT takes a while to get all the hardware and drivers in sync. Hopefully they don't give up and also upgrade to a better CPU.
There has got to be some firmware bugs causing high power usage, but also the CIX CPU is fabbed on TSMC 6 nm process which is a couple generations old.
And note that Radxa launched their O6 with the same SoC earlier this year, and they haven't brought down idle power consumption either.
There's also the Orange Pi 6 Plus, and the Radxa O6N with the same SoC, they would all benefit from the power issues on this chip being resolved. Not sure if it'll happen.
