Now Tesla recommended charge percent becomes 80%, how much difference for battery health if I use 90%?

If I only charge to 80%, the real range will become too short, and I must charge more often.

Then don’t!

Thousands of posts have been written on battery levels & longevity with all kinds of charts and graphs. If you plan to sell your car before the HV battery warranty expires then this whole issue is moot. But if you want to dig into this, just search the forums.

If you need 90, use 90. That’s about all there is to it.
