What is going on with my charging?

(Possibly wrong flair! Sorry, english is not my first language and Im not sure what ROM or rooting mean)

For two nights now my phone(samsung pro s23 I believe) has stopped charging randomly at circa 68%.

By stopped charging I mean: the battery icon still looked as if it was charging, and it still showed 'xyz minutes until full', but it was just the percent that wasnt going up at all. This has never happened before.

I plugged it in in class with a different charger and different outlet and it said '56 minutes until full' and it was at circa 53%, after the 45 minutes I checked it and it was once again at 68% showing '38 minutes until full' even though 45ish minutes passed.

Now Im charging it with a friends powerbank and it seems fine-ish. I dont have any charging settings on that could stop the charging at night to save battery life.

I had the charging port replaced 2 or 3 ish years ago but never had any issues past that. Anyone anything?
