My SR was 211 on its first charge w/ 3 miles, now it's 207 2k miles later. I've ran it down and back up, charge nightly, etc. I am getting about a hundred actual miles out of it since it is in the 30's - 40's around here now. Makes me realize perhaps I hopped into EV's a little prematurely for my family. I can deal with it but just hope my wife doesn't make a mistake and get stranded this winter, since there aren't superchargers very close here.230 is not bad, thats only 4%. Mine is 9%. 200 at 100% (supposed to be 220) (SR not SR+)

The 12-22 miles difference is likely due to weather conditions. Is it raining? Is it really cold out? Are you running the heater in the car? That kind of thing will cause the range to fluctuate. I've noticed my range drop quite a bit now that it's below 30 out. Heck, it dropped when temps were in still in the 50's too. I used to only charge every other night too, but now I plug in every night just to be on the safe side since it's so cold out, but I only charge up to 80%.
I just finished my 1st cycle yesterday and that was were I got the 231 miles. Going through my 2nd cycle as we speak.
You keep asking "should I", but I would join with several other people who would say no, you probably shouldn't about this whole thing. What you are doing is just trying to give yourself a warm fuzzy feeling about the number you see on the screen. You're not doing anything actually helpful to the car.Should I go with one more 10-100 or just go straight to 90% charges moving forward and see what happens?

People are still trying to "solve" something that is just a phenomenon of all of the cars that goes back 6+ years. Within the first several months, that estimation algorithm gets "off" somewhat and will start reading about 5-10 rated miles low. All cars. Always. The 10-100% thing just lets the estimate get more visibility, but isn't helping the battery with anything.Just trying to get some feedback...that's all. I have had actual had a few people in this forum say give the 10-100 charging cycles a try considering the car had the drop at such low miles. I can see you disagree with that and respect that. I would like to know what you do with your Model 3 and if have any suggestions or do you think I shouldn't worry about it. Thx.

Here's a description about this that I wrote up a year ago:
Who wants in on a class action lawsuit? ;-)
"I think people are talking past each other or not understanding what is being told to them. This is not "being "told something else entirely". These are valid answers for accomplishing two completely different things. You would get entirely different instructions for making beef stew versus baking a cake because they are different things.
The 20%-80% recommendation is what to do for your constantly daily habitual process to achieve the least physical damage and longest possible life of the batteries.
The process of running it low and then charging it back up to really full is the procedure you can do every once in a while for addressing some estimation algorithm and balancing issues to get more accurate readings.
Those are two different purposes and both are good recommendations for different uses."
It just comes down to your preferences for your situation. Sure, toward the middle is most ideal, but that's not realistically enough range for most people's uses, so go higher for however much range you need to be comfortable with your driving amount and not being worried about running short.Thanks for the info. I am new to the game and just trying to see what is going on. My daily commute is around 70-80 miles so would you then recommend charging the car daily to just 60% and then charging to 90% maybe every couple of weeks?

This part is good to know, though, it's not a linear effect of how beneficial each step away from the top end is. Using 90 instead of 100 is the biggest bang for the buck, already getting away from the most damaging effects. 80 instead of 90? A little more helpful, but not nearly as much difference, etc. So when I hear that people drive only 10-15 miles a day and are still using 90% constantly, I tend to think, "You probably don't need to have it quite that high to have plenty of range." With your 70-80 miles, I would probably just go with somewhere around the 80's % and leave it and not worry about it. 60% is unnecessarily low for your amount of driving, doesn't gain you much more and is going to be stressful.
I would. If you come home with 78% and want to skip a night, you could, but for myself I plug it in every time I park at home, even if I think I might go back out later that day. I have my charge scheduled for midnight, so it won't actually charge up in little increments. If I were to make exceptions to plugging it in each time, I'd be bound to forget at some point and miss charging when I really needed to. That way if I my plans change and I suddenly need a maximum charge the next day, it's already plugged in and I just need to use the app to push the charge limit up. Also, if I always have my normal 80 or 90% in the morning, I'm ready for any reasonable surprise that pops up, where if I let it sit at 60%, and something comes up, I might have to scramble for a charge.All great info....thanks for the help. And when you say charging it somewhere around 80% you are saying plugging it in everyday when I get home and letting it charge back up to 80% correct? Should I be always plugging the car in now matter the SOC when I get home?
Doesn't matter much either way as long as you're not going really high or low in the charge state. I do usually wait a day or two partly because we don't do much driving, and in case we go out again later that evening. (And sometimes because we have a pretty good deal with 6 cents per kWh charging at work, so I'll sometimes wait a day or two to make that worthwhile.) It still never really gets below half, so it's not going really low. And I don't want this thing of the charge port latching and unlatching 3 or 4 times a day unnecessarily if I were to plug it in every time I got into the garage. That is a mechanical wear item just like door latches or window motors/switches, etc. or other kinds of mechanical parts that can wear out from a lot of use. Maybe it's a little cautious, but I'm out of warranty on my Model S, so I would like to not overuse something that causes it to break earlier.All great info....thanks for the help.

Not to raise an old post, but in my Mid Range I get ~57.5 - ~57.9 kWh. If the Mid Range has a 62 kWh pack, and I had NO degradation, that would put the "reserve" at ~4kWh. Sound about right?Try this and report your result....
Look at any of the consumption graphs. Take the Wh/ml and range.
Note battery % (as a fraction).
kWh = (Wh/ml x remaining range) / (battery % x 1000).
Ex. (240 x 110) / (0.5 x 1000) = 52.8kWh
I always get 52.5kWh as the answer. But not tried since V10.0, will report back.

But these are just minor preferences and conveniences and I'm not necessarily doing what works best for various people.
