Good point on the 80% to 100% charge. The last 10% can take another hour. So let's say charge to 95% in an hour instead of 80% in 30 minutes.
Real life data (for example from this heavy fleet user
https://www.tesloop.com/blog/2018/8/...s-in-two-years) who charges typically to 95% and shows only 13% battery degradation after 300000 miles and, even more importantly, apparently showing no further degradation. And we are talking here about 5 year old battery technology, not the latest and greatest.
I am not sure why there is such a widespread negative misconception on reduced battery life and long charging time, I keep reading comments like yours but the reality is very different. I don't know, maybe this is coming from the public perception from cellphone batteries which are unfortunately incorporating programmed obsolescence.
