100% Charged for 150 mi?? (UPDATED)

[AlmostHuman]

I've never understood why it has to be one or the other. They both require math; either you are estimating your miles per percent (which the nav does anyway) or you are estimating your typical efficiency (e.g. you get 90% of rated on average). Personally, I prefer miles over percentage because it gives 2 pieces of information; state of charge and degradation. Percentage only gives one metric, SoC. My iPhone shows me the battery percentage, but details in the settings shows me the battery degradation. With the Tesla, you have to rely on your own (or an app's) calculation to estimate degradation. It doesn't really matter which you use on a day to day basis, but periodically estimating degradation from the rated range is quite useful.

Yeah totally agree, it doesn't have to be one or the other. I like % so I can keep my battery at a SoC I like when I don’t need to do a long trip.

?‍ That's highly specific and only true if you take the same route all of the time. And it changes over time because of loss of capacity, and seasonal changes and topography are all calculated by Tesla. So go by miles.

Battery degradation is so little as to not enter that chat.

We are both showing our age. Simply means there are many schools of thought on a topic and getting in to a deep conversation about it may not be fruitful.

You keep using that word, I don't think you know what that word means.

That's not true. A 7-15% degradation is going to be almost 25-50 miles on a long range Model 3. That's not insignificant.

So someone who gets used to a regular trip taking 40% might find it strange that after time, they need 43% for that same trip. That destination didn't get farther away.

Lol, imagine buying a larger range car and that regular trip becomes 30%. That destination didn't get closer.

You swap EVs with your partner and it has a different "% to work amount". What? Lol this whole conversation is just asinine.

100%. See what I did there?

That's clearly not true, since the OP claims their 100% charge only shows 150mi rated. Normal degradation has lower impact as you mention, especially since the navigation system provides such accurate calculations that nobody really should need to worry about it, but rated range display can alert you to issues that might otherwise be hidden by percentage only view.

Why do you keep mentioning religious? What does that even mean? Lol

This conversation is getting weird. Lol

See now that is a well crafted point

Oh the internet!!

All joking aside we did get a little off topic from the OPs issue.
As @eswimm pointed out if you charge to max miles and you see 15x miles something is off. Good reminder to look at once in a while.

Can I get the last 10 min of my life spent catching up on this thread hoping for something meaningful or some resolution back?

That's clearly not true, since

...you have no proof this isn't just a system fault.

Battery degradation to 50% capacity at launch isn't degradation. It's system failure.

Your destination miles would also have that fault.

So there's no reason to look. You'd notice your % peeling off at 2x the normal rate, as well.

I ride a short-range EV. I am super-familiar with what works in percents to miles on the main display. I just know it takes 15% to get downtown, and 25% back. It takes 25% to go up the hill on a hot day and 45% when it's freezing out. You just get used to it.

Because EPA miles don't represent your range, you have to translate anyhow. And you need to know the percentiles to know how dire charging is.
