Outcome of testing with your kernel 6.5.0-2007-oem:
1) with your kernel batttery drain is 8% in 4 days;
2) with Ubuntu 22.04 6.2.0-37 kernel also 8% in 4 days;
3) with power reset workaround (see #49 above) it is 2% in 4 days.
So my conclusion is that 6.5.0-2007-oem has same battery drain still.
Hope this helps you find a good solution.
