Questions about the ID.4 battery capacity and cold weather

So I'm a new EV owner, having purchased the ID4 Pro S in July. I love driving the car and everything about it except for the lack of range and the shortage of fast chargers in my region. There's only one EA charging station in the entire state. Hopefully more are on the way. I digress...

During warmer weather I could charge the battery to 80% and the range indicator said that the range was about 230-240. Now the weather is changing in the Upper Midwest and I took a short road trip to a location where I left the car out overnight for 4 nights without driving it and the temperatures dropped into the mid-to-low 30s. On my return trip, a charge to 80%, which took about the same amount of time as it did during the summer months, only got the range indicator to 160-175. I got it home to my garage where the car is charging in a partially enclosed area (warmer than outside, say around 60 degrees) and it doesn't seem to have improved. Does anyone know how long does it take for the effects of being outside to normalize once I return it to the garage? Is this dramatic change something I can expect for the entire winter (and for it to potentially get worse), or am I doing something wrong?

Example.....battery is at 30°F and left without being plugged to L1 or L2....when you start and go driving it will take 20 or more minutes depending on how much waisted heat ( 50+ MPH will lead to minimum use of coolant heater) to bring it up to 49° usage for battery coolant heater could be observed with appropriate scanner.
German video about ID.3 battery heating after start. Battery indeed is heated to 10°C (49°F) with a 5kW PTC heater:

Another morning, no battery heating when battery pack was around 10°C and ambient 7°C
