I just bought a galaxy s 2 skyrocket. It didn't have a battery or door. So I bought a the battery and door from amazon. I got the battery and when I put it in the phone. It still had a little charge left in it. it came on so I plugged it up. that way it wouldn't go completely dead. I left it on charge for 12 hours and the battery didn't go past 2% so I left it on for 8 more hours. It was still 2% so I unplugged it to see if it would hold charge. As soon as I unplugged it the phone died. I thought it was the battery. So I sent the other battery back to amazon and got another one and I continue to have the same problem. I have cleaned the battery and the terminals. I bought 3 chargers also. None has worked. So please try and help me?!?!
