Yep, that's what they told me yesterday as well. Just try to balance it out once a month etc etc...

Mine is 235 and has been so for well over a year. +/- 1% = 2.3 miles so variance is understandable.

I recently did a range charge for a road trip over Thanksgiving. 43k miles on the odometer, 90% at 232, 100% at 257 RM. Range mode off.

Interesting ... how did you get above the new delivery range of 230 for a 2015 Model 70?
No idea. It's always been high. I'm back down to a 90% of 218, which seems like an accurate number.
I just hit 70k miles / 5 years this weekend - my battery is a D from early '14 with ~50 k miles 90%@225 for the last 2 years or so (100~250)
I've got a new 75D. I was a bit amazed by the 90% range it put on my screen, 253 miles. I drove it for 110 miles today and the range dropped from 90 to 51%, which seems accurate with the estimated range. I just filled her up till 90% again and shows 254 miles now.
EDIT:
It misread my screen when peaking in the car, it actually went op to 267 miles (429 km).

Late 2013 (P25XXX) S 85.
~ 60K miles.
90% range is 232.
May I ask, what is battery rebalancing/balancing? Do I need to do it? How would I do it?

Based on your 90% I'd say you're in good shape.
Basically it's just running the battery down to as close to zero rates miles as you are comfortable with getting, then plugging in and letting it charge all the way up to over 93% (usually 100%). Then once you get the "charge complete notice," go for a short drive and bring it back down to ~90% as leaving the car sitting at 100% for hours and hours is not very good for the battery.
/Edit if you do go to 100%, be aware that last 1% can take forever to fill. It will say 5 minutes remaining for about 45 minutes at the end before it finally fills up and completes.

The rated range for a Model S70 is 230 and 90% is 207. Perhaps you are a light footed driver and your kW/mile is less than 300.
I am light footed. Rated range isn't supposed to factor in anything except battery capacity, though, (unlike ideal range) so the way I drive shouldn't matter for that number.The rated range for a Model S70 is 230 and 90% is 207. Perhaps you are a light footed driver and your kW/mile is less than 300.
And now that you mention it, my lifetime kWh/mile is indeed low. I think it's 268 or something. I can do 80 MPH with AC on for long distances and rarely hit 320+. I have had no measurable degradation since day one, either. The numbers all seem too good to be true.
I wonder if the early 70's weren't some kind of limited higher-capacity battery with some fudge factors in the numbers.

According to Electrek, the orginal 60kWh and 70kWh battery capacities were actually larger than rated
All other battery packs are smaller than rated...
Tesla’s hacked Battery Management System exposes the real usable capacity of its battery packs
- Original 60 – ~61 kWh total capacity, ~58.5 kWh usable.
- 85/P85/85D/P85D – ~81.5 kWh total capacity, ~77.5 kWh usable
- 90D/P90D – ~85.8 kWh total capacity, 81.8 kWh usable
- Original 70 – ~71.2 kWh total capacity, 68.8 kWh usable
- 75/75D – 75 kWh total capacity, 72.6 kWh usable
- Software limited 60/60D – 62.4 kWh usable
- Software limited 70/70D – 65.9 kWh usable

My 90% on my classic 85 is now at 237 rated miles (just under 4 years, with 45,500 miles). I just did a range charge to 100%, and it was at 263 rated miles. I continue to feel very fortunate, after seeing so many of the posts where people have lost quite a bit of range.
It's that leisurely Hawaii lifestyle. Your car lives a stress free life and it shows in it's battery range. Send it to Minnesota for a winter, that range will drop down to 210-215 in one winters time
At 2.5 years, 36K miles, my 85D is hanging in there at 90% = 238 and 100% = 265.
Considering a move to 100D but wonder whether it will offer such a favorable degradation curve as my existing car.
The added range is a great incentive, but one thing seems to be for sure, the 85 packs are bulletproof. No degradation with lots of Supercharging (like the 90 packs), good overall bang for your buck. I feel like those early 85 packs, ('B' Series and later) were just overbuilt monsters. Only downside is they weren't really 85kWh in size, more like 77kWh iirc.

90% on a S75D should be 233 miles. A seven mile loss in 1,000 miles seems high to me. When you car was new, did you ever get 233 miles at 90%?
I have a 2016 S90D that was delivered on 12/27/16. I lost 6 miles in the first 6 months and thought that was too much. When I talked to the Service Center, they said that it was not abnormal. Unless your car continues to lose a lot more miles, Tesla will probably not have a solution for you.
