That may need repairer attention.

I agree. Might also be interesting to try one of the wireless chargers if you have one available. That way you might be able to identify if there's an issue with the charging plug / cable or with the battery itself not taking a charge. Either way, especially if the phone is under warranty, sounds like you want to work with your carrier on a replacement or repair.
