2 months in and 90% yields 254-255 averaging 254.6. ODO is only 1807.5 miles though. Currently on v7.1 build 2.11.54.

I'd settled down to 252 at 90% until recent "warm" (for the season here in Massachusetts) weather and it creeped up to 253 and then 254. With the cold snap over the past few days, it dropped back down to 252.
3,000 miles Range mode is off.
What did you start off with when the car was new?
I received my S90D on September 23rd. My first 90% charge was 261 miles.
Since then my 90% range has also been declining.
Yesterday I hit a new low of 243 miles at 90%. That is a 7% loss of range in 5 months.
I have never turned range mode on.

I doubt you have actually "lost" range beyond the typical 1% in the first 6 months or so. It's a software estimation error issue that will likely be corrected in a future update.Yesterday I hit a new low of 243 miles at 90%. That is a 7% loss of range in 5 months.

The above chart shows a linear falloff over time. I seriously doubt it's suddenly going to level off. How much range must one lose before folks stop believing it's a calibration error? 10%? More?

So some have been told by Tesla. Until someone drives down to something low like 5% and reconciles remaining battery % with the wh / mile * miles driven, I don't think anyone will really know for sure.
There have been several updates since this was first postulated but no improvement in range indicated.
Silicon in the anode decreases cell life as the tradeoff for getting higher capacity. How did Tesla overcome this tradeoff?

I will stop believing it's a correctable algorithm issue if Tesla doesn't come through on their written promise (to me and several others in this thread) that they are updating the software issue soon. My internal clock has that patience wearing out by the end of March. I've cycled down to 3/4% from a 100% charge two or three times with no appreciable effect.
As cited previously with numerous posts in this thread, I too have this challenge with my S90D -- from a lifetime 90% charge high of 255 rated miles at delivery on 10/5, to now something between 249-251 depending on however the crazy algorithm is calculating things at the moment. It's not correlated to temp swings or simple rounding errors in my case, and I appreciate the data for some others with 85kWh batteries clearly show it is over longer spans of time. I have though, reported my situation to Tesla and have it documented (see previous posts) that my battery itself has no issue and it is a firmware problem how rated range is being calculated/presented, with no ETA for resolution.So some have been told by Tesla... How much range must one lose before folks stop believing it's a calibration error?...

We're worrying about fantasy range not meeting hypothetical range, when we all know real drives falls short of either anyway.
