If we go with the car analogy, then the gas tank would become smaller with age, but also the fuel line which feeds the engine becomes smaller with age. So overall capacity is reduced, but in addition to that, if you try to floor it when the tank is at 40%, the engine will stall.
If you had only puttered around town (putting only a light load on the engine), you could have fully used the remaining 40%. So the gas tank does still have 40% capacity remaining at that point, it just can't deliver surges like it used it.
- slantyyz 9y agoI guess we should take a look at how the electric car makers do it then? They have this problem and deal with it now. Not having any experience with electric cars, I can't speak to how it's done.

AFAIK, most of the battery degradation on phones can be attributed to heat and suboptimal operating temperatures. An EV will heat up / cool down the battery, treat each cell as an independent unit during cycles etc. They will degrade a lot slower compared to phones. Most EVs even after years of use have decent battery performance and some manufacturers (like Tesla and BMW) even go with 8-10 year battery warranty programs. I think they don't see much abuse like the tiny phone batteries.
