Battery Tesla or OEM Chevrolet

We've been driving two EVs, a 2012 Leaf since Dec2011 and a 2017 Bolt since Sept 2017.

In the Bolt we lose about 40% range at -20 and lower. Bu the range is so good to begin with its not an issue.

I have a Tesla Model 3 I got last year and drove it every day during last winter. No problems other than it uses a bit more of your battery to go. Also using the heat uses a bit more battery as well. I would say about a 20-25% loss in range compared to summer driving.
