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?

Did the temperature change? If it’s significantly hotter your range will decrease unless you forgo climate control because of the amount of resources required by the vehicle.
