I've had my 2019 Premier for 4 months and have the following observations:
After a full charge my range varies from 230 to 270. It all depends on recent driving behavior. If I spent the previous day on the highway.....230. I f it was spent around town....270.

I've also noticed that flipping on the A/C instantly drops the range by 20 miles.

I've also noticed that flipping on the A/C instantly drops the range by 20 miles.

And if you live in a colder part of the world you will see lowered range in the winter. Pump your tires back up to compensate for the several pounds drop in cold weather. Running the resistance heat will use more power than running the AC heat pump. Even if you preheat the cabin while plugged in, and use only seat and wheel heat in winter, expect to see lower mileage from denser air.

To be a little pedantic, it's not the actual range that is varying, it is the guess of the range shown on the GOM (Guess-O-Meter).

If you drove around town yesterday, it won't actually help you drive further today. And turning on the A/C or heat won't take exactly 20 miles. If you precondition before you leave and have the car cozy, it may not use much at all. A long trip in bitter cold may exact much more.

I have found that preconditioning in cold climate area's does nothing beyond give a warm fuzzy (literally) when you get in the car. If it adds range, it's single digit range .... which for the record I'll take what I can get.

At the very least, it warms up the battery. I think the amount of time spent preconditioning matters too. The battery has lots of thermal mass and warm air in the cabin takes a while to change the temperature of the things inside. It's my operating theory that two full preconditioning sessions would be best when it is very cold out.

Doing some controlled experiments doing the same commute on days with nearly identical weather might be informative, if you want to have a go.

Now that I have a thingy, I can most certainly add some data to it. Sadly, I may need some hand holding to know what is relative and what isn't. I'm very green and new to it. And yes, if the car is sitting outside in a -6 F environment then I do revise my statement .... in that case, if we're talking about heating the battery to that extent than yes, that might be a factor. But for the cabin heat, for the person who has their Bolt in a garage ..... I believe it's minimal. I have been super impressed at the efficiency of the cabin heater and although I do see it impact the range I feel it's efficient. The cabin of the Bolt isn't 'large.' I precondition many times a week.
