Charging to 100%

I just got a 2025 Model Y RWD and am loving it!Charging question — I see in the Charging section of settings that 80% is recommended for daily driving and 100% only for trips. I live in an apartment complex that has free chargers although I can’t necessarily charge my car every day or leave it on the charger all the time because there isn’t always a charger available/it’s courteous and encouraged to move once you’re fully charged so others can use the chargers. Can/should I charge to 100% if I only need to charge once a week-ish? Should I be charging more often? I only really drive around town to the grocery store and gym and don’t need to charge for multiple days (I only lose about 10% a day with sentry on). I was thinking it would be nice to stretch longer between charges if I’m starting from 100% rather than 80%, especially since I’m not always guaranteed a charger, but want to do what’s best for battery health.

Follow up question, is there a minimum % that I should plug in (I was thinking 20%)? If I was at 20% I’m not concerned with running out of charge while out and about, I’m more concerned with what’s best for the battery (i.e. if you shouldn’t let it ever get below a certain % unless on a trip). TIA!
