Allison Huettner double check your charger and your charging cable. Make sure that those are in working condition. Check the charging port make sure it is not obstructed or otherwise clogged, dirty etc.. If all that is in good working order then there is the possibility that this is a bad charging port, bad battery or logic board issue.
