phone does not charge after lcd screen glass replaced

i replaced the cracked glass lcd screen assembly on moto e 4 plus. it turned on, had 18% battery. I checked operation by using maps, linked to my yahoo email etc. it all was working. i left phone alone and when i returned the batter had run down. when i tried turning on the yellow triangle with red exclamation mark inside circle with small red mark indicating 0 battery came on. plugged in charger and left alone for awhile came back and no change. battery not charging. checked charger and it is charging other devices. is this the charging port ,how do i check that or get new one? the battery, though, it did work till it died, it was rough getting it out and sustained external wrap damage? any reliable sources for parts? i have to retrieve the data on phone, what went wrong?
