Data is a bit light on the ground given we haven't had masses of EVs for all that long. But I wouldn't necessarily have this expectation based off of phones and laptops.

EVs have really high-end battery management systems and cooling, which will have a huge impact on battery life.

Heck even my phone is lasting better these days with just better software battery management in Android. My current oneplus 9 is going on three and a half years old and hasn't notably degraded in battery life. Whereas I'm pretty sure I remember all my previous phones having noticeable battery degradation after a year or so.
