The charge cap is a bit pointless day as I know, more of an urban myth than reality

Nope. It’s very real. Tesla loudly advises to charge to 80% at most. There was also a thorough study of this a few years ago. Will try to find it.
The tl;dr is that you ideally want to keep the battery dancing around 50%, as much as possible.

Alright no here's a better one, but this is under artificial "constant" conditions and the previous paper mentions dynamic, real world conditions have battery life fairing better. Still, 85%-25% > 100%-40%.
