Battery charging issues. Recognizes it but doesn't charge.

Alright, I've posted a similar question, but that one got lost in the abyss that is tech problems.

Alright, so a few months ago i dropped my moto x and the screen shattered. I got all the parts, fixed it, and the screen is functioning like normal. The main problem is that the battery will drain extremely quickly, and the phone will not charge. The phone recognizes the cord as plugged in, but the battery menu says not charging. I have tried two phone chargers, both do not work. I have cleared cache, soft reset, and still nothing. The front flash is also missing, which i was thinking might cause the battery to discharge quickly. I have already replaced the battery, and it still has the same problem. I am beginning to think that it might be a charger port problem, or maybe even a problem with the logic board. (maybe even flash? who knows?)

Also if anyone has a good suggestion in how to glue the screen to the frame of the phone that would be great thanks. (1mm 2 sided tape is not doing the job)
