7a rapid battery consumption even after battery change

Hey so my pixel 7a has been depleting battery really quickly lately, like it'll go down 10% in half an hour when im not even using it and it gets really hot. I literally JUST got the battery changed a few hours ago and the problem hasn't resolved, it is depleting just as quickly as before, is this something that can be repaired or is it just worth buying a new phone at this point?
