Probably already addressed here or elsewhere but I also have a question about range.

I have a 10/2018 build M3 LR RWD. Have been charging to 90% since day one. (Have 30K miles) Maybe to 100% a handful of times for long trips. SOC indicates 258 miles @ 90% charge.
Is this considered low? Is this normal? Is it inaccurate or should/can it be “reset”?

Typically driven fairly conservatively, mixed freeway/streets, with A/C due to hot SoCal weather.

Please advise. Thanks in advance!
I have a Oct 2018 LR RWD also with about 24k miles. Currently, at 90% I typically have an estimated range of between 270-275.

Before COVID I used to run the battery down to 60% every day and charge back to 80%. Occasionally, I’d charge it to 90% (once every month or so) and only to 100% maybe 3 times total.

Since COVID, I typically let the battery run down to at least 40% before charging (which takes over a week or sometimes almost 3 weeks now) and then charge it back to 80% or 90%. I’ve never charged it to 100% since COVID.

In the past 2 weeks, I’ve been taking regular ~160 mile trips, 2 or 3 times a week, and during that time, I regularly charged it to 90% and my estimated range has been slowly creeping up: at 90%, it showed 282miles.

Do what you will with this information. While my estimated miles may be higher than yours at 90%, I wouldn’t worry too much. I bet if you take a few long back to back trips like I did, and charge back to at least 90% after each trip, you will see an increase in estimated miles.

That's REALLY low, but you'd need to cycle the battery once or twice to be sure.

So I cycled my battery from 8% to 100% @ 285 miles.

I drove and ran it down to about 20% and charged to 90%. Or 262 miles. So no improvement with 1 cycle.

Just passed 30,000 miles. Will be 3 years ownership this October. (10/2018 build)

Oh yeah, still on original set of MXM4 18” tires. Getting about 224 Wh/mi lifetime.

Am I on par with most of you out there? Not really concerned. Just curious.

Those numbers all look reasonable. But that 224 lokks exceptional! After almost 90K miles my usage(P3D) is closer to 265.

How long did it take you to run it down to 20%? I found if it’s one continuous drive rather than many short drives, is when my estimates start going up.

Coming up on 18.5K, just did a full charge which I hadn’t done since traveling back in early June. (although unplugged when it still said 40 minutes to go). car showed 317 with 40 minutes remaining. Not sure what I’m doing but it seems to be working.
