Have you enabled the fast charging in device care option or not ...? If no then go to settings >> device care >> battery >> more battery settings >> turn on fast charging

[ChandanMallick]

i think it is a bug. so give an error report to Samsung

[avi666]

how can i report

[ChandanMallick]

Okey let me explain you. follow the steps below;
Open Samsung Members app >> Click on get help section >> on the feedback section click on error reports >> on the categories click on power/battery/charging >> then select the frequency as always >> then write down the problems whatever you're facing and allow it to collect your device log.
NOTE: Please put your device on charging while submitting the log report.
It will take some time and you'll get a response from Samsung authorities.
Thank You
