Service center texted me this, can someone explain?
So tesla did downgrade from 240 to 220. But it's showing only 204 miles at 100%.
Service center rep is wrong. The main range meter on the 3 never takes driving style until account. It's always rated range.
I'm not so sure anymore. Seems like there are lots of reports like the OP now, and it would explain my numbers better.
Aw crap, not this again! The rep is wrong and needs training. This is problem where Tesla has hired too many people too fast with insufficient training. Rated miles is a constant times the number of watt hours that the battery management system detects in the battery. It does NOT change with driver behavior. The ability of the battery management system to assess what is in the battery can get out of calibration over time. The “cure” is to cycle battery a couple of times (deep discharge to 10% or less and charge to 95% or more). Caution: charging above 95% and leaving the car sitting is not good for battery. So only cycle when you can drive it down a bit soon after charge.So tesla did downgrade from 240 to 220. But it's showing only 204 miles at 100%. Service center texted me this, can someone explain?

Exactly how has your 100% range increased?I am not convinced the rep is wrong. When I first purchased my 2016 MX last year my lifetime wh/m was around 377. It’s is now around 350 and since my 100% range has also increased. Wouldn’t this support the reps statement?
It absolutely does not. There's a reason the range display is called rated range. You can see projected range in the energy screen, which does in fact account for driving habits and on that same screen you can see the fixed rated efficiency line on the graph.I would suspect the range algorithm factors historical usage patterns. This is supported with a lower lifetime wh/m allowing for additional range and would be no different than any other vehicle where there is an estimated distance. This is also true with our Chevy volt where the range has also increased with greater efficiency since purchasing used. I have been using teslafi data logging for the MX which further supports the rep showing the 100% range slightly increasing over time as I drive more efficiently.
Stop guessing! You are wrong. Take it from 7 year Tesla owner and many others who have had years of experience and are not guessing. Rated range does NOT factor in driving. Then it would not be “rated” range.I would suspect the range algorithm factors historical usage patterns.

So I went down to 5% battery and charged it to 100% and this time it's 203 miles. I will try this few more times, other then that not sure what to do. Hopefully software update will fix it.View attachment 452577
I drove about 15 min after fully charged
