That is true, but for safety reasons since friction brakes heat up, you don't want to rely exclusively on fiction braking for long mountain descents. An alternate approach, which I sometimes employ, is to drive fast (55 mph) on the descent. That way there's more wind drag and less regen. Plus it's fun.
I should also say that I'm not *that* concerned about battery degradation due to regen. One of our big mountain descents is still significantly less stressful than a Quick Charge session, since the regen is not continuously maxed out, is spread over a longer period of time, and involves less total energy into the pack. And we only do it once or twice per week. It's just something to be aware of if you are an EV geek...
Also, sorry to have strayed from the topic. The big point is, if you really want to maximize battery longevity, we believe it's best to try to stay in the center, or somewhat below the center, of the SOC range as much as possible. But more importantly, use the car. If using the car requires charging to 100% or draining to almost empty, then do it.
