You need to know via many miles you have. Three percent doesn’t tell you a lot.
I actually find miles very preferable, since with my driving style I usually get close to the rated EPA efficiency (unless I am having some fun). I check my wh/mi every so often and de-rate if I need to though. I would really hate them to get rid of miles as an option, please don't give them any other ideas about how to ruin the UI!It makes me wonder why they insist on A) having miles be available as an option at all for the battery display or B) making it the default. It's such a misleading, nearly meaningless figure. I can see an argument that if they just displayed estimated kWh they'd invite speculation and whining over degradation etc, but the mile display does that anyway... Just make the 30 mile average visible somewhere as your estimated range like gas cars have done for decades and call it a day. Then it's clear that "I have 70% left, and at my recent pace, that's probably enough for around 200 miles" without all the other baggage...
Not true. My displayed range goes up and down despite the charge level % being set as the constant. Tesla service confirmed the display will vary based on driving habits.
I feel like this should be on some quiz you need to pass to be allowed to post.Displayed range is based on regulating agency certification (EPA) and is not adapted based on driving pattern. Your driving behaviors and environmental conditions can impact your car's efficiency, and therefore its range. To see estimated range based on personalized energy consumption, open the Energy app.
Did you try turning it on via the Climate controls and not just with a voice command?
So I'm confused. How would them saying "You have X miles based on a totally arbitrary estimate" mean any more than "Based on having 4% remaining, and your recent driving history, or your destination and anticipated speeds and slope, you have Y miles". I think you're disagreeing because you aren't understanding how meaningless the "Energy Display: Miles" indicator is.
I hate to break it to you.. but from Tesla's own web site first question in the FAQ (emphasis mine):

Rated miles are directly proportional to the almond of energy in the battery. Knowing rated miles tells you how much energy you have. Note that it does NOT tell you how far you can drive. KWh would be a better unit and lead to less confusion, but rated miles tells you the exact same thing.So I'm confused.

Percentage tells you how much energy you have relative to total battery capacity. How much energy is this? Who knows? To figure that out, you would have to know total battery capacity at that very moment. And you don’t have that info, so all you can do is guess. Percentage gives you no actionable information.
This isn’t my opinion. These are verifiable facts.
I find it to be somewhat accurate. Have you ever run out of battery? How do you know it is inaccurate. Miles isn’t important when you have 300 left, but it is important when you have 30 left. I think you are complying that since the range displayed when your car is more than 50 percent charged is often wrong, the miles display is meaningless. It is there, you have plenty of range. But when you get closer to running out 30 miles is more meaningful than 3 percent.
Back on topic - where is my .4? and more to the point, where is a usable layout....no games, no farts, no 'visualizations' or spinning cars...
I’m not trying to argue that there couldn’t be improvements to the data that is displayed. But rated miles (despite the misleading units) provides information that is more actionable than percentage.The difference between percentage and doing the mental gymnastics to turn "EPA Rated 207 miles" into kWh and then back into a meaningful number is negligible. Battery degradation isn't some dynamic, random, ever-changing thing. It's an extremely slow and steady gradual decline, which is further distorted by the fact that the car's BMS drifts off more often than it's spot-on. And EITHER WAY, actual usable capacity would be reflected if the range indication was the dynamic one from the energy graph. None of these arguments for the Energy Display: Miles setting holds any water. And as proven in countless posts on these forums, it doesn't do Tesla any favors anyway because people still post constantly about why their car with 402 miles of range only shows 398.
Rated miles indirectly tells you how much energy the BMS thinks the car has, in a unit which is misleading, and which is no more useful to an actual driver than a percentage display plus the already existing range calculation from the Energy app. Period.
