Have to agree with Lozza12.
Seems like every 30 seconds I come across a thread on here or somewhere else asking about battery degradation. I completely understand the anxiety that comes from switching to a completely different way of powering our cars, but people pay far too much attention to the concept of battery degradation. Especially because the only indication we have is the computer's best estimate, which can vary widely from reality.
Just last week there was a post on the Facebook group from an owner who just rolled over 100,000 miles. His would fully charge to an indicated 97% of his original rated capacity. When asked about his charging habits, I had to laugh… He routinely charges to 100% and discharges down to the low single digits because of all the miles he drives. Pretty much the worst case for battery maintenance, and his pack is still in outstanding condition.
I don't blame the OP, I think everyone is prone to thinking like that. But the examples I've seen with both the older Model S crowd and the much newer, but occasional high mileage Model 3 owners, have kicked that thought firmly out of my mind.
Batteries aren't a problem. I'm going to plug my car in and drive it… I don't even look at the useless mile counter either. That thing disappeared for a much simpler percentage two weeks after I bought the car. If my battery proves to be the extremely rare outlier and starts dying early, I have a nice long battery warranty to handle it.
Here's the FB link I mentioned above, BTW.
