Thank you both for getting involved! I get the same result from both @msfujino deep sleep and @PJ_Glasso post #59 sketches.
Here is my current setup. The board with the red LED that connects to the USB Li ion battery is a boost converter where I removed to outgoing USB port and put pins in its place. Sorry if this butchering of the board hurts your eyes, I suppose it does. I know I could directly go from the USB port of the battery, but due to the pins the boost converter was the easiest way for me to enable the current measurement without cutting up another USB cable*. To measure the current, for lack of better equipment, I used those two clips to connect the multimeter on the high side. I have to push buttons connecting to ground on D2 and D3 and ground and 5V on the respective pins, nothing else
…oh no, it says I can’t embed media!.. let me try dropbox links to the pictures… you’ll have to click them because it only shows those broken image icons, sorry about that!
Board support package, BSP, thanks for spelling it out for me! This is what I got. I hadn’t noticed that it picks the “Sense” by default, but I just repeated the measurement after selecting non-sense and it did not make a difference.

*in case you are wondering what is going on there: I am using two of the XIAOs that communicate using BLE. After developing both sides of the code I used this boost converter with a CR2032 to test things. I made a rookie mistake in the BLE code and I think that drained the coin cell quickly. To prevent that for further testing, I put the USB C cable in place so that I can use that Li battery and keep using the pin strips. If you are thinking why on earth did he keep the boost converter, it’s because I also wanted to measure how much current it can provide because the data sheet said “500 to 600 mA” and I wanted to know.
