Recently I switched my settings from rated miles to percentage, and I like it. Instead of thinking about how my rated miles convert to actual miles, I find that I can plan on using 30% for my daily commute. What setting works best for you?

I'd take percent if it had at least one decimal precision. They're no reason the dash can't display miles and percent. Ideal miles are completely useless. Might as well display moon miles.

95% of the time (subtle pun intended), I use percentage. Makes more sense to me on a daily basis.
when I am driving long distance between superchargers, I use mileage so I can estimate better when to move on.

I like the megajoules option. Having a 270 MJ battery sounds more impressive...
I always wondered why the charging screen couldn't show both...or have a button to allow you to toggle back and forth with one tap.
Instead of going through the longer process of going to settings, etc. to toggle back and forth, someone pointed out a shorter way to toggle back and forth now is just to copy your driver profile and have one set up for miles and the other for kWh. That way you can change back and forth with just a couple taps.

I am hoping that 8.0 will take care of this. Why the display cannot show both miles and percentage is beyond me. My Remote S app on my iPhone shows both, why can't the car?
I rather like the idea of have all of the options displayed. Sometimes I have managed to beat ideal (!) but other drivers cannot have been happy about me puddling along at a precise 45 mph.
Normally I display percentage maybe because of habit but any of them can work so long as we understand precisely and accurately what they mean.

Percentage. Percentage. Percentage. There is only one percentage number to keep in mind vs. different flavors of miles that get confusing.
Simple math too. Find out your true 80%-90%, 3 miles per KwH and voila, you've got your actual/physical/real/<insert word of your choice> mileage.

I use rated miles because, duh, it tells me how many miles I can go before I need to charge.
Percentage is irrelevant and meaningless to me.

Precision is irrelevant because the accuracy isn't there. The SOC displayed is an estimate, whether in miles or percentage, because the SOC can't be measured directly. Don't take the result you see displayed too literally.

That's exactly what I do. Two profiles... Art Pct and Art Miles. Sweet

I do realize that "rated range" is not perfectly accurate since it can be affected by weather, terrain, etc. However, in 40,000 miles of driving, I have found it very accurate and very useful.
I just wouldn't know what to do with "percentage"... I guess I could convert it to miles using something like rated max range * percentage but why not just display rated range.

I always select "web page views available" instead of "percent battery available" on my iPhone.
Just FYI, on my P90D my actual Mileage per Full Charge has ranged from 155 miles up to 264 miles. Just too many variables to count on an accurate mileage estimate.

Me too. Also, I was stressing over the different mile values every time I charged up, was worrying about degradation and so forth.
Also, it occurred to me that ICE cars don't calibrate their gas gauges in miles. They could, by taking the EPA combined fuel efficiency rating and fuel tank capacity into account. A lot of ICE cars have a Trip Computer which calculates how far you can go based on recent past driving style... and so does Tesla! This is a much more accurate prediction of range than a static "Rated Miles" number on your fuel gauge. So I like my "fuel gauge" to tell me, as a percentage, how much juice I have and use the Trip Planner for accurate range predictions when I need it.
I just can't think in terms of percentages--not useful. So I keep it on rated miles and just ballpark that it's a little high. If it says 190, I can probably go 170. I'll just generally drop 20 or 30 off the number, and it's close enough. I don't worry or stress about it, and most of the time I don't need to care. If I'm on a longer trip and need to pay more attention to making a driving segment work, then I'm not really using either, because I'm using the estimates from the energy app on the center screen, not whatever is on the console display in front anyway.

A long time friend who has a Founder S told me that his rule of thumb is really simple and takes into account the worst case which is winter... He banks on 2 real miles per percentage of charge. This gives him ample inter Superchaarger range of 200 miles which is pretty much very good. It also simplifies the estimation by doubling the percent to get your range.... So 80% = 160 miles of worst case range.
I suppose winter in the western mountains could break this method but here on the East Coast it seems to work and is simple to do and understand and estimate.
