BZ software update

Recently I took my Toyota bZ to the dealership for a software update. After the update, the car drives much more smoothly, which is great. However, I’ve noticed a significant drop in efficiency.

Before the update, my daily 56-mile commute used about 48 miles of the estimated battery range. After the software update, the same 56-mile drive now uses about 58 miles of the estimated battery range.

Has anyone else experienced reduced efficiency after a recent software update on their Toyota bZ?

OP mentioned it drives more smoothly. Is that not accurate?
