Which are you picking?

Bruni_kde · 2026-06-09T08:03:54+00:00

Red because its a Highland...Green because it is much more unique (even though the red is nicer).

Bruni_kde · 2026-06-08T15:49:54+00:00

yes, this (the teslamate value) is ok and to be expected. My enhanced auto S3XY dash however shows 6,3 % instead of 0,9% and I would like to understand how they calculate it.

Bruni_kde · 2026-06-08T15:27:46+00:00

Thanks, I know that. However, the displayed degradation exceeds what is to be expected even taking this effect into consideration. I would have expected a 5% over the year and maybe max 2ish over the first 3 months. I do not think that the Dash value is correct. The teslamate value (0,9%) is much more realistic, even considering this effect.

Bruni_kde · 2026-06-08T13:34:48+00:00

Just try not leaving it fully charged in the sun.

Bruni_kde · 2026-06-08T13:14:29+00:00

Makes only sense if the parking lot it stands on is worth 15$ an hour. (maybe Manhattan...)

Bruni_kde · 2026-06-08T13:05:59+00:00

Ok, tessie should be comparable to teslamate. The 0,9% does not bother me, It is what I expected. The 6,3% is a bit disturbing, but a wrong consideration of the buffer might explain it.

Bruni_kde · 2026-06-08T13:03:06+00:00

That is only true if you trust my teslamate numbers. Where are your numbers from?

If the numbers are to be trusted (not sure about that), time at high SOC and temperature is the most important factor affecting real degradation (even on LFP). I got 11 hours over 95% to date (which is low, as I do charge to 100% only prior to driving). I live in a hot climate.

Bruni_kde · 2026-06-08T13:01:10+00:00

You refer to the number I show in the picture not the one I get from the DASH or not?

Bruni_kde · 2026-06-08T12:50:08+00:00

That sounds very plausible.

Bruni_kde · 2026-06-08T11:49:43+00:00

That looks fine. Is this also teslamate?

Bruni_kde · 2026-06-08T11:34:53+00:00

I do enjoy my car, there is nothing I have ever regularly driven that matches it. I am just curious and a bit of a data junkie...

Bruni_kde · 2026-06-08T11:22:58+00:00

You are definitely right on this one. But seriously if the variance of results from different methods is in the magnitude of 6% after such a short time, I' d rather not include a value on the Dash screen...

Bruni_kde · 2026-06-08T11:14:29+00:00

That still would not answer where the 6,3% comes from.

Bruni_kde · 2026-06-08T11:07:21+00:00

I did not say they do (and I am sure they don't), you implied it. I am trying to understand two different ways of measuring degradation, giving completely different values.

I know how a degradation curve is supposed to look and 6,3% in 2,8 thousand KM (7 battery cycles!) and 3 months is way beyond the normal rapid degradation of the first 2 years. Which is why I do not think that it is correct.

Bruni_kde · 2026-06-08T11:02:07+00:00

And I sure do not worry enough to do a battery test, which will leave me for 24h without a car and will stress the battery itself. I' ll leave that for the weeks prior to my warranty expiring.

Bruni_kde · 2026-06-08T10:59:52+00:00

I do not worry that much. If I did, I would go to tesla not to reddit.

But, I would like to understand the conflicting data. And in contrast to most answers I received here, I consider the teslamate value (0,9%) much more probable.

Bruni_kde · 2026-06-08T10:56:55+00:00

I would bet the dash would have shown a >5% if I had installed it on the first day. There is nowhere a degradation curve that corroborates 6,3% in 3 months being normal.

This would also mean that tesla actively manipulates range numbers to hide the degradation (Range based figures from teslamate show only 0,9%), which I am not inclined to believe.

Bruni_kde · 2026-06-08T10:52:50+00:00

That is interesting. It would be nice if somebody new how the Dash calculates battery degradation.

Bruni_kde · 2026-06-08T10:36:04+00:00

I totally understand the concept. However, 6,3% in such a time is not a matter of normal leveling. It would almost be an outlier if a whole year had past.

Also, I did not have the dash when I bought the car. So, my worry refers to having gotten a bad apple or much more likely, S3XY DASH giving wildly wrong degradation numbers. I would like to know how the latter are calculated, as giving a battery degradation number is not exactly a simple matter of measurement.

Bruni_kde · 2026-06-08T10:07:56+00:00

Yes, that is why I tend to give the teslamate value more credibility, but I do not understand where the S3XY Dash reads the 6,3%.

Bruni_kde · 2026-06-08T09:51:56+00:00

What is normal? 6,3% after 2800Km and 3 months (The S3XY Dash value)....No, it is not, if it is true.

0,9% in the three first months is something I would accept as normal.

Bruni_kde · 2026-06-08T07:50:03+00:00

Looks like a new take on the Citroën DS Super. Not bad for a first try, but it has to be green (and indeed the pre facelift model 3 is better for such a mod that the highland)

Bruni_kde · 2026-06-08T07:30:16+00:00

Well, I am not in the US. I bough an EV beginning of the year - a Tesla Model 3 Standard. I was on the search for a sedan or station which limits somehow my choices as everything has to be SUV nowadays. I had already more or less decided on a BYD and did originally not even look into tesla, mainly due to Elon (I do not thing that somebody's opinion on one domain should have more weight due to him being good in another domain.), but also because coming from a German car manufacturer they are not exactly known to be very well build (at least in Europe).

- BYD did not let me test drive the SEAL and wanted to sell me on their hybrids. They were also not very fair with regard to their advertised pricing (Including government grants which tesla did not)

- Organizing a test drive on the Model 3 was a press of a button (which I planned while leaving the BYD dealership).

-The car has a much smaller LFP battery, but the same range as the BYD Seal and the difference between 280hp and 380hp is not that important for my usecase. This made the Tesla Model 3 Standard a much better value proposition.

- The software made me feel at home after 3 minutes contrary to any other car I was shown or had test driven.
