Should I be concerned with my battery efficiency?

I leased an Elite a little over 2 months ago. I have 1,500 miles driven. Haven’t had many complaints except maybe battery efficiency. I hadn’t thought much of it since I’ve only owned the car in the winter. But recently I thought this was too much. I live in Illinois btw.

I enjoy using adaptive cruise control which I have been using less and less because it seems like that might be using more energy.

I have a 21 mile commute to work(one-way) and I usually warm up the car 10 minutes prior to driving.

This morning, I ran some errands so the car had been warmed up for a while and left for work with a range of 109mi at around (43% battery). Google maps showed a 20 mi trip to destination. The battery range when I parked showed 71mi. Drove 70-75 the entire way, mostly using one pedal driving. It was 20 degrees in Chicago today.

Total battery consumption was close to 40 miles on a 21 mile trip. Is this normal with this weather or should I be concerned? I found that the battery range always depletes way faster than the speedometer increases. Typically, I find that consumption is close to 35 miles one way, regardless of traffic.
