Once SST is sorted the main battery drain seems to be USB A cards installed.
See below; Lines 234 and 237 are where I removed all USB A and just had two USB C cards. This achieves 320 and 306 mw of drain, the lowest I have seen on this thread, which is borderline acceptable imo for modern standby (though nothing compared to the 125mw/hr of the 2021 spectre x360). This is compared to 850-1000mw of drain per hour (the other lines) with 2x USB A and 2x USB C cards installed. Can anyone replicate?
