Please I have a problem with my phone. I exhausted the battery and now I was able to charge it. After so much problem trying to charge, it charged up to 75 percent. when I plugged out the charger and plugged it in again (due to Power Issues), I discovered it wasn't charging. It showed 75% and the screen stayed frozen (while off). So I decided to turn it on and then realised it wasn't charging. While the charger was in, it wasn't charging at all. I later realised if I drain the battery to zero and leave it off, it will keep charging But extremely slowly. I am confused as to why this is happening. My phone software is up to date. Please what can I do and is this a hardware or software problem. I will be glad to get a response. Thanks a lot.
