Can you share which model?
Thanks!
Ho do you measure power consumption? I'm quite sure your tool isn't very precise. My R4 never got under 3.5 without anything connected and fully idle. It's virtually impossible to be that different.
Did you use Sinovoip's image or real OpenWrt?
I have USB-C power meter, and the details are quite accurate I believe, I don't know what power type you use, if you choose DC jack and measuring directly from AC side of course there will be a lot more power being used due to the loss in the power brick, while my measurement is directly on USB.

Just the one together with AC power bar (not very sure about model number), but I have many USB-C power which work with my R4, I tried to connect a USB HDD to R4 to increase a bit the power consumption and it's still fine.
To stress it a bit, I connected a 2.5" spinning HDD to my R4, running tansmission torrent download, power consumption is roughly 6-7W only.
Note I haven't plugged anything into SFP+ yet.
well my wifi 7 card shows up, but the Drivers are part of Kernel 6.9 far as i know and i don't know if it can be used as a AP or not.

Which card exactly did you order and where did you buy it?
This card shows up on ali but two times the price of intel be200...
But Intel card doesn't support AP mode.
If you already own the card, boot up a general purpose linux distribution, update the kernel to v6.9~ and check how far you can get (iw list will tell you about the interface capabilities, hostapd should be available for most distributions; and even network-manager afaik offers a basic hotspot mode). I'm not saying this should be the real, long term solution, but it's an easy approach for a quick test (at worst even running from a USB stick, without touching the installed system). You will have to do quite some experimenting either way, as these cards aren't commonly used for this purpose (or on OpenWrt at all).
Judging from design and specs, this is more intended for client uses - how far it may go in AP mode remains to be seen.
It was pulled from a MSI HERALD-BE NCM865 WI-FI 7
and Amazon have them.
I know that, i'm not dumb ...
Looks like the Linux Desktop UI's need updated for Wifi 7.
Qualcomm QCNCM865 with Linux Kernel 6.9.rc pulled up 1060 lines with iw list
This is a Qualcomm client card - so it is questionable whether the firmware and drivers support an AP mode at all.
The Upstream Linux driver also tells you that the AP mode is disabled.
You can see this by the (no IR) flag

So, as loaNga0m already implied, it's just as useless for AP uses as an Intel card, which is kind of a bummer.
You can remove the (no IR) flag in the driver.
But as already mentioned, this is a client/station card.
The WCN cards support AP mode in the 2.4Ghz band - I am not aware of anything else.
You can also remove the flags on the Intel cards to enable AP mode in the ≥5Ghz band - but this doesn't do much except crash the card firmware
Regarding Hardware flow offloading: Even with the latest snapshot, I still have a problem with it. If I enable hardware flow offloading, my wan speeds drop to 0. LAN connections work fine and as expected, but WAN connections are horrible.
Here an example without offloading:
And here with it enabled:
Neither the system log nor the kernel log indicate any issues.
What could be the cause?
Please try to limit the RAM size to 2 GiB (by settings bootargs in U-Boot to contain mem=2048M) and report if that fixes the issue.
Now its working as expected, thanks 
But is that a final solution or a workaround?
You may try this patch and rebuild, let me know if it helps
