OK, my phone kept shutting off even with battery still left, sometimes 40% sometimes 20% sometimes as much as 70%, as soon as I plugged it in and it would start right back to where it was (as far as the battery %). After about a month of this I figured the battery was dying and I needed a new one so I came on here and used the guide and replaced the battery. Then when I started my phone and used the front facing camera the phone would freeze up so I ordered a new one of those. But I realized my battery never charged and it died on me, so I thought maybe I received a bad battery and ordered another, when I got it it had about 20% so I plugged it in and came back about half an hour later, and I lost about 2%, so I tried 3 different cables 2 different wall chargers I tried the laptop the pc even the car charger... nothing. I restored it, no change. So I ordered a new charging port put it in and still nothing. What could the problem be? I'm at about 7% battery and counting.
