OK...I am confused. Earlier in the Year, I am sure I heard Elon answer a question about the recommended daily charge level, to which he said 70%. Then last week, I believe there was a tweet from Elon that recommended 90%. So....which is it?!

I’ve read a lot of people’s opinions, and I don’t think there is a straight-forward answer to this.
Pretty much everyone agrees that having your car at close to 100% or close to 0% for extended periods is not good for the battery.
And batteries will degrade over time, regardless of how you treat them.
So the question is how much of a difference does different charge levels make?
My personal belief is that the difference between 90%, 80%, 70% does exist (with lower charge levels being better for the battery), but it is probably not worth worrying about. Maybe after 5 years, it might make the difference of a few miles of range, but not much more than that. This is not based on any scientific facts, but just my feeling after doing a lot of reading.
My M3 is set to charge to 85%.
Huh. My explanation of the two differing priorities people need to balance to come up with their charge limit got a disagree. Someone doesn't like having to make decisions?
