I bought Sony Ericsson XPERIA x10 on ebay.com from USA. I'm living in Georgia (in Europe). Our electricity power is 220 v. When I got it a battery was charged till 40%. I did not turn on a phone and then I plugged in a charger (USA standard) to charge till 100% without inserting my SIM CARD in a phone. An indicator in the front of the phone was lighting in white without blinking. After some hours a battery became empty. Then I inserted a SIM CARD and began to charge again without turn on a phone. After this action an indicator in the front of a mobile was lighting in red without blinking. After the battery charged till only 41% charging was stopping itself. Then I tried to continue charging but the battery gone empty and if I try to charge again an indicator is blinking in red and the battery is not getting charged. What to do?
