Nothing is free! The reason the Tesla has such good battery capacity retention is because it has extra capacity from the start. When you buy a 80 KW Tesla you are actually getting a 90KW battery and that capacity is not accessible until it's needed in the future. I am not sure they will keep this with the Model 3 but most likely they will as it reduces owner griping about something that every EV owner should know about but does not.
Having said that, I do wish Nissan would fix the software so that I have a 80% charge limit on the battery that would be relaxed over the years of ownership so that I can get more consistent range and not charging batteries to full always definitely helps them not lose capacity down the line, as the last 20% charging is the hardest on them. Since LIon batteries don't have memory it's ideal to keep them in the 20-80% range at all times if your driving pattern allows it - and mine definitely does at about 20% for one commute day.
This could be a software switch in the settings like Tesla has where it asks you if you want to enable maximum range or battery conservation? Such a simple thing and everyone's a winner.
