    Possible 35% battery degradation after 57k miles?

    With default settings and my 75D car, ABRP estimates 37 minutes and 13% battery usage for the home -> office trip and 38 minutes (16%) on the way back. The avg time is very close (unknown / 37 min today) but battery usage is way off (19% / 24%). Avg energy / mile on the way back 408 Wh/ mi...

    Possible 35% battery degradation after 57k miles?

    The service request that I did was about two issues: battery degradation and also high energy consumption. I provided all the numbers but they canceled my service appointment and sent me the link to the range tips. Yes, that was unexpected and rude.

    Possible 35% battery degradation after 57k miles?

    Nothing feels unusual when driving, the brakes are cold after driving. I scheduled an appt with Tesla Service but they canceled as "we do not see any failures or alerts at this time". Charged the car to 100%, yesterday's average: 414 Wh / mile over 65 miles - this is ridiculous

    Possible 35% battery degradation after 57k miles?

    Sentry off, cabin overheat protection off, headlights off, AC on; drop after 10 hours on standby - 0% Better route planning does not exist. The round trip includes probably 300' elevation change... energy was compensated as we are talking about a round trip. Return trip was 33 miles, took 36...

    Possible 35% battery degradation after 57k miles?

    New data with no Sentry or other "vampires", headlights off, AC on: - 26 kWh corresponds to 47% battery drop (80% -> 33%) => max charge = 26 / 47 * 100 = 55kWh == 73% of new battery (75kWh)... is 27% capacity drop over 57k miles normal and expected !? - unrelated: 408 Wh / mile average over 65...

    Possible 35% battery degradation after 57k miles?

    I am using the Sentry, but not Cabin Overheat Protection. That is interesting, I read that Sentry mode uses 300W, in 10 hours that is about 3kW. Will look for numbers when the car is parked. The e-Golf has a 36kwH battery and can do about 100 - 110 miles on the freeway -> 330 - 350 Wh / mile...

    Possible 35% battery degradation after 57k miles?

    Interesting data and comments, thank you! My e-golf averages about 350+ Wh / mile, so 385 Wh / mile for Tesla doesn't look outrageous to me. At 80% full the car reports 180 miles, so 100% is about 225 miles, but this info is useless. Shouldn't the car (as any other car) report the miles left...

    Possible 35% battery degradation after 57k miles?

    AC on, headlights on, music on.... ridiculous that with a car that advertises 256 miles you cannot do 130 and we have to charge daily. We also have an e-golf (38kWh version) with 40k+ on the odometer that pretty much does 100 miles daily (111 advertised) with a few miles left at the end of the...

    Possible 35% battery degradation after 57k miles?

    My wife has 65 miles commute freeway / city with not much traffic so she drives 65 - 75 mph on the freeway. I guess that is kind of an average commute. The car uses about 100+ miles of battery on this 65 miles daily drive, so we have to charge the car daily. My calculation of the battery health...

    Possible 35% battery degradation after 57k miles?

    Hi Everyone, I am a proud second owner of a 2018 Tesla S 75D with about 57k miles. Still not familiar with the car, but the range is not what we expected, as apparently we can only drive about 130 miles on a full charge. Yesterday my wife drove 65 miles and used 25 kWh, 51% of the battery. That...
