My phone has recently started having charger issues. When I'm able to get it to charge it will fully charge the battery, but sometimes it will actually decrease in charge when on the charger. Just last night I had it on the charger while the phone was off and it was showing 100% charge but when I turned it on it actually only had a 2% charge.
I brought it to ATT today and they said it was the charger port by looking at the pin. I'm not fully convinced since I compared it to my friends s3 and it looks exactly the same.
Would anyone have any idea on what the problem might be?
