Why has my battery all of a sudden stopped working?

In the stores when you go to get your iPhone repaired they offer the originals and the replicas obviously the original are more expensive and they have the replicas with different grades I bought a replica screen before and it smashed when I dropped it the tiniest bit ever whereas the better screens withstand more, but the real problem is when I got it fixed all of a sudden the battery stopped working when it died and it won’t turn back on at all is there any chance the store could have replaced my original battery with a terrible replica one ?
