Says it charging but wont charge
So I have a ZTE score. I plugged it in to let it charge. I wouldn't. I switched chargers to see if that was the problem. It seemed to be. I left it on the other charger. An hour later, it said it had only charged 21%. I turned it off to see if it would charge better, but when I turned it on it went to 16%. I tried this once more. I and currently at 4%. I just got this phone a week ago because my other ZTE Score's charger port broke. I need help. Any ideas?
