>Ever have your phone or laptop not hold the charge it used to when you first bought it?
While true, the analogy is bad. The phones (and to some extent laptops) are notorious of the overcharge. The Li-Ion (cobalt) normally should be charged to 4.22V or so. Tool batteries usually do not go over 4.18V. Yet, the phones are happily pushing 4.35V - which provides longer life per charge initially, plus a proper planned obsolescence later.
At the very extreme end, Apple Watch batteries have a 3.87 V nominal and 4.45 V end of charge voltage. Most lipoly pouch cells would turn into a balloon trying to do that once.

EV do proper battery management AND cooling.
