First time charging......

Set to charge to 85%.......

Probably quite a good compromise % between range and battery longevity. Although instinctively I'd now probably go to 75 to 80% SoC if you didn't need the range. It's mainly higher temps and lots of DC charging that erode available capacity over time...but it is sort of inevitable anyway.

Thanks - so many conflicting views. the dealer said 83% - yeah right try setting that on the profile....

A few friends have said to keep it topped up at 80%.....

To be honest I’ve had 90% SoC set as my default on the Tesla since new. It’s now at almost 70K miles coming up 5 years and hundreds of recharges. When look at degradation over time. It’s lost around 8% or so…

85% seems most popular on here.

Remember the PB+ has already got 10% off limits to preserve thd battery, which is very conservative.

Thanks - should have remembered that. So far 80% and it’s reporting 181 miles……

Ignore that. Its just the guess-o-meter.

It also increases when you use the car more.
For actual usage look on the PCM / app.

Yep I guess

But isn't the low Tesla battery deterioration because they keep at least 10% of the battery unused and gradually release it into use over time - specifically so that the battery appears to degenerate more slowly? Once that has all been put into use by 7 years (or whatever the warranty period) then it will deteriorate much more quickly. At least that is what I understood with Tesla. Still interesting to hear though.

Beats me how Tesla manage the BMS/pack. That's just my experience of using the car these past five years. I've decided to keep the X when the Taycan arrives, but in any event I'm not expecting a cliff-edge battery deterioration at 7 years. There's plenty of other stuff that can go wrong with the car...

No Tesla do not use much of battery as spare. Porsche uses about 10% but not Tesla model 3 and Y. Some reserve at the bottom end perhaps, 1-2 kWh.

Is it not a worry with Tesla's that the 'phantom drain' (especially with Sentry Mode) uses so much battery when left and yet the car has so little in reserve?

I assume Tesla owners just leave them plugged in when away for any length of time?

Not really.

sentry mode when left on will draw quite a lot of power, but it is switched off when the SoC gets too low.

I have recently left my Tesla unplugged for two weeks and only lost about 2 or 3 percent. It is more than Taycan but not horrible.

Not at all. I left mine unplugged on the street for over three weeks and it had only marginally dropped. The major factor in drain is the car waking up periodically - which is exacerbated by checking in using the app. It’s best to just leave it alone and then the various systems beautifully hibernate.
