I also was concerned about range degradation and scheduled an appointment to have the batteries checked. Here is the response I got from the service center.

Hello,
This is Katie, from Tesla Rocklin. We have ran a battery health check on your vehicle, and found no faults with the cells; they are all charging to the proper voltage.
We have found that in cases where the battery is consistently charged to a lower state of charge, between 60-80% capacities, estimation becomes less accurate and tends to underestimate the true capacity of the battery. The result is an incorrect reduction in the displayed range estimate.
This does not affect the true range of the vehicle, as the end-of-drive conditions are based on real-time battery measurements of reducing battery power, rather than software estimates.
We recognize the inconvenience, and negative user experience associated with this range estimate. We are developing more accurate estimation algorithms which will be pushed over the air to the car when available.
Here is a great article regarding a Model 3 that was able to get more than the EPA rating/ what was displayed by adjusting their speed. Tesla Model 3 travels 606 miles on a single charge in new hypermiling record - Electrek
A good practice is to keep the consumption screen visible for true predicted range and monitoring driving habits and environmental conditions.
