Has anyone ever charged ALL the way to 100%?

No it's not possible. Tesla locks the vehicle remotely for attempted overcharging and issues a repo.

I tried to charge my MSP to 100% using the portable charger on a 15amp plug at my girlfriends house, but the relationship didn’t last long enough…..

I regularly charged to 100% (twice a week), and to 85% or 90% on the other days, all Supercharged. After 16k miles in 5 months, my battery degradation was the same as reported by everyone else here.

I mean to the point it finally stops charging. In my experience it takes a long time to “top off.”

Yes, twice. I’m not sure how long it took because it was overnight both times.

That's been my experience too...we charge both 2020 MYLR's to 90% every day. And to 100% when we are going on a trip. One has 37k, the other 13k.

On regular trips, it takes nearly the exact same battery percentage as new for round trips. We're talking a few percent more at most.

Yes, probably around 8 times total. All the others for road trips. Started at 100%, drove to a supercharger and topped back up all the way to 100%, arrived at my destination at 20% which kept me good to get to a supercharger the next day.

The most recent time was this last week, where I found this guide and decided to give it a try. Have been leaving the car at low SOC's to try calibrating the BMS and get a more accurate reading of the battery degradation, but prior to that I did a 100% charge, and kept it plugged in for a couple hours after it reached 100%, to do some cell balancing.
