IPhones start slowing down after a year

Tesla slightly understates battery capacity from the factory - to give future headroom and the appearance of less battery capacity.

In this case, are they 'guilty' of leaving extra performance/range on the table when the vehicle is new?

Tesla does not leave any headroom. If they did, then the car would appear to be able to charge to its original value for a while -- but it doesn't:

What Tesla does do is pretend that the bottom 20% of the battery doesn't exist. That's because it's very damaging to use it at low charge.
