Okay so my phone will only charge on certain chargers lately, but with the right charger, it would charge fine. Last night I kept having to twist the charger around for it to charge. Today I woke up and went on it like always and I unplugged it a bit, and it dropped from 100 to 3 percent immediately. I plugged it back in and it went to 100, so I unplugged it and ten minutes later it was back at 2%. Does anyone know what is wrong?
