Samsung S22 Ultra (at least) has a 'Protect Battery' setting which limits charge to 85% .

Its been a feature since at least the S9. Source: Had to 'fix' my girlfriend's phone only charging to 85%. Was a mystery how that setting got randomly enabled, really.

I can't recall for certain if my old S7 had that option but I don't think it did.
