Is 3% battery degradation a lot for the Tesla Model 3 LR RWD


  • Total voters
    54
Car specs: Model 3 LR RWD with 42,000km/26,000 miles after 1 year 4 months.

Situation: I've been driving and charging the vehicle to 90% every night. Last couple of days I noticed that the car only charge to 87% now. 3% degradation seems high for 1 year use.

Questions:
1) Are any other owners experiencing a similar situation?
2)Do I need to re-calibrate the battery?
3)Should I contact Tesla?

I'm not even sure I understand your "situation"? You've set your car to charge to 90%, and it doesn't? It stops at 87%?

Is there anyway to re-calibrate? What I read from the other threads is to discharge to 5% and fully charge to 100%.

Move the slider again in the car or in the app until it "snaps" to the 90% level. And try again.

This issue has nothing to do with capacity loss - in fact there is no way for you to easily gauge capacity loss when you use % as you are doing. Which is fine.

Defective batteries will sometimes refuse to charge to 100% but that will give you an error message saying so and that is pretty rare (so very unlikely to be your issue here).

Funny thing, just the other day I charged my car to 80%, slider was on that mark. But when the car stopped charging it showed charge of 83%! I had recently taken it down to near zero (1% I think) so it may have recently recalibrated. I’m not sure if this means I lost range or gained it, but apparently the slider stops can get confused.

I slid the battery bar down and back to 90% stop and today, it charged to 90%. Seems like this fixed the issue. Many thanks for your helpful insight!
 
Tesla Model 3 Performance here, had delivery in early October 2018, approximately 66% of total charges on Tesla DC Superchargers (yay for lifetime free supercharging) with other 33% of charges using 120/240V AC where I almost always charge to 90% though sometimes to 100% if I'm taking a long trip. Per Teslafi I've had somewhere between 2.84%-3.08% degradation after driving 43,625.87 Miles. (Note: I didn't start using TeslaFi until 12/08/2018 at 5,788.28 miles)

For almost 44k miles, and charging to 90% and 2/3rd on SC, 2.5% degradation is pretty excellent.
