Fast charging not working

1.Check if fast charging is enabled in settings
2. Change either of cable or adapter and try charging using it. (original samsung adapter and cable)
3. Try to clean charging port with soft objects or dry moisture inside if any (do it at your own risk, you're not supposed to damage port)

i am facing the same issue with fast charging on s22 ultra, i recently updated the September security patch,, is it cause of that or what?
