Yeah, I’m pretty sure I read that somewhere too. The reason being overcharging just once basically kills them, so they give it a lot of leeway and say it’s 100% well before that.

… Aren’t devices designed to only charge the battery to 90% (and report that as 100%), because actually changing a battery to 100% is pretty harmful for it?

You’re thinking of cars, industry and others that have high value batteries.
Power tools, smartphones etc charge to the maximum 4.2V/cell, sometimes even 4.3V (some chemistries safely allow it) because the average person just wants the maximum runtime and will replace the equipment before the battery degrades significantly.
