In any case, it's strange there are many other users following my charging pattern that have not seen any degradation. I've been reading many messages and 50 kms per day driving and charge to 90% is SUPER common. So it's weird why it only affects some and not others.
Also, it's strange Tesla has not "fixed" the BMS estimation "problem" after so many cases and bad press. If they're aware of the problem I'm sure they would be trying to fix it ASAP.
Few things to mention here - a lot of people don't care or don't have Stats or TeslaFi apps. They charge to 80%, keep the car at % and never see if there is any change in their rated km/miles.
Unless you actively look for it with stats apps, like people here, if you only drive 50kms a day and keep the car in % you will never see any issues or degradations, because you are only using 10-15% of the capacity...
And even if you drive to a Supercharger, you still wouldn't notice anything, because you are mostly an inexperienced driver who follows what the car suggests and the car will probably just suggest to get a stop in about 200kms, which you can easily do on 80% battery...
So the simple answer is - people don't care for the range.
But there are people like us who care.
The other thing to mention is that there are a lot of S and X drivers in these forums. Their cell chemistry is different, their BMS is different. So you might hear someone say - I charge to 90% and have never seen an issue. Which brings us back to the above IN ADDITION to the fact that they drive an S or X, whichs screws the stats.
I also don't know if its really a BMS issue or some cell issue in combination with BMS or some battery gauge. Tesla is doing expansion and trying to deliver 100,000 cars each 3 months I think they have limited resources. Plus the amount of cars on the roads and the small number of people complaining - I don't think this is a priority. It might not be that easy to fix either. No idea.
But the simple observation so far has been that charging 70-90% daily and almost never discharging below 30%-20% on a Model 3 is a bad idea.
I have 10,500 miles (16,000km+) and am stil at 75.9kWh from 77kWh new, which gives me 498km displayed at 100% or 0.02% range degradation (1.5% real). Have never charged from 70%-90%, not even once. Most of my charges happen between 30% and 80% and I also do a lot of highway stunts where I go from 100% to 7% and then back to 80% (never charged to more than 85% on a Supercharger) I also have 60% DC vs 40% AC charging, which is supposedly bad.
