I forgot to unplug my phone after fully charged for more than 30 minutes.

Did it affected my battery life on my Samsung Galaxy A33.

I think it will be fine, just check your device diagnostics if something is wrong with your battery

No. Samsung phone and it's original charger stops the charge once full. I overcharged my tablet for the past 5 years and it's fine
