I was using wireless charger 10W and it did not do fast charging but it was overnight.  Saturday morning Verizon update came out for Samsung and since then it only charged 80% after 6 hours.  I wire charged it with no problem this morning.  Any ideas, I like wireless charging at night and frustrated after the update it does not anymore.

Same here, I have the S21 and the long 3 device wireless charger. My phone says 42% Fast wireless charging 1 h 42 m until full, but it charges very slowly.  Definitely not 1 h 42 m

@mar915 While I have no evidence of this, it appears that Samsung has started enforcing it's charging specs.  Chargers that worked initially with the S21 no longer work in some cases.

I have a Samsung Super Fast wall charger which I plug into my wireless charging cradle and it still works fine.  It seems to affect chargers that are not PD 2 or 3 certified.
