The guessometer in a battery electric vehicle is usually set to take into account the weather and recent driving patterns (the main exception is Tesla whose system or rubbish because it’s never realistic - I understand it always uses the theoretical range initially and so won’t be accurate). None of them will at this time of year (possibly not at any time of the year) match what the results were in the laboratory test (under wltp). Volvo (and all other manufacturers) have to indicate the wltp figures for bev range as they are with mpg for ice cars
Setting off on a cold day will always use a disproportionate amount of the battery as it has to heat the cabin (and to some extent the battery). Travelling further will give better results
This is the same on the bmw i3 that I had for three years and the Jaguar iPace that I have had to 2 years 10 months (66000 electric miles between the two) and will no doubt be the same on the c40 we are about to get
