Lower and lower miles.....

[RYCO]

I have had my refreshed S90D since the beginning of June '16. When I would charge it to the recomended daily charge, it would go to like 272 miles. Slowly its getting less and less. After just over 4k miles, this morning its at 265 at a full recomended daily charge. I have done a few 100% charges on trips and such, but just 3 or 4 times. Whats up with that?

Have you run it down to 10-20% and then done a full 100% charge? It needs that from time to time to rebalance and recalibrate the rated range. If that doesn't work best to complain in writing to your Service Center.

Ok, ill try that. Last week i did draw it to 10% and only charged it to the 90% daily charge though. Ill have to try that again.

let us know your results.

90% of 294 = 264.6
Seems to me it is right where it should be.

Battery degregation is the worst the first year. I wouldn't panic.

Yep, I missed that. You're good at 265 the 272 was an outlier.

265 is perfect really at 90%. But you'll likely continue to see some degradation in the first year mainly, and a little more if you are in a colder season climate during the Winter - 50-60 degrees and less... But it should stabilize after the first year, maybe after 2% loss on average, down to about 260 or so.

I've seen some degradation on my P85DL. 90% used to be 227 miles. It's now down to 225 miles after 25K miles.

I'm getting 247 at 90% on my 90D that isn't even a year old so.... I think you're fine...

If you're adjusting the charge level with the in-car on-screen controls you might not be at 90% ... You might actually be at 89%. I set my daily charge to 80% and I found that when I adjust with the car settings and later look at them with an app like the Remote S app that lets you apply a numerical percentage, the amount may be off be a percent one way or the other. This could explain your situation.

Please download one of those apps or use Visible Tesla to determine the exact charge percent you are using.

Good luck.

I have checked it on the car switching to energy and miles. It's charging to 90%. I guess android doesn't have those apps either.

So, I got it down to about 18% then did a trip charge to 100%. Seemed to work as it said my rated miles was 294. Interesting though, I drive it to work and ended up having a late job so I drive my 2015 GMC 2500 home and left the tesla at my office. (I was covered in mud and didn't want it to get all over my tesla.) Leaving the tesla at my office at 204 miles at 8 am yesterday, not plugged in, when I got in it today after work, at 5 pm, it was at 193. What causes 11 miles to go away in 30 hours or so? Is that normal? It was like 110 degrees during the day.

Probably cooling the battery. Do you have temperature conditioning active?

I've always had 265 at 90%

What is that? The temperature conditioning? Are you talking about running the air conditioning while I'm not in a car? If so no I did not have that active.

@jeffro01 Whoa... less than a year and 90% at 247? Can you say that is a defect and have the SC replace the battery? I'm at 255 at 90% with my 90D. I've driven a little over 14k miles and took delivery 3/14/16

He's talking about "Smart Preconditioning".

 

[RYCO]

He's talking about "Smart Preconditioning".

What is smart preconditioning? Is that where the AC kicks on automatically when it thinks you're going to get in the car soon? If so that is turned off.

Yes, this is from the Owners Manual:

• "Smart Preconditioning: If on, Model S predicts your driving schedule and automatically
  
  adjusts the temperature of the cabin based on your last set temperature and your driving schedule, making Model S comfortable and ready to drive. It may take some time for Model S to learn your driving habits and if you do not have a regular driving schedule, it will be unable to identify a pattern.
  
  Note: To conserve energy in situations where Model S has a low charge level, smart preconditioning may not occur.
  
  Note: Smart Preconditioning is available only if you save your home and work locations
