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.
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.
EV do proper battery management AND cooling.
