Full 100% charge is good for the LFP batteries which have been standard in Model 3 and Model Y since 2021.

Indeed, Tesla recommends to charge to 100% at least once per week.

As far as I know this isn't true, LFP batteries degrade more when charged to 100% than if they're charged to less, but the remaining charge can't be estimated accurately unless you do:

(They still degrade much less than the other kind of battery Tesla uses, however).

Interesting, it seems they want people to charge to 100% so they can precisely estimate the state of charge on the road. Still, as you say it doesn't seem LFPs get degraded that much when sitting at full charge.
