Same problems here seems to be an awful phone for the charging fault, Recently I had problems with my xperia x10 not connecting to my PC but charging fine, I purchased a new usb lead and this sorted the problem with connecting the handset to a PC but now the phone will not charge.
When I plug the phone into the mains and go into settings/about phone it says (charging AC) and the battery on the display moves up with the charging symbol in it but still remaining on 48% for over 3 hours.
I have then plugged it into my PC and on the phone I selected "charge phone" and get the same problem the phone says charging via USB and the battery flashes as if it is charging even the battery gets luke warm like it does when charging but yet still stuck at 48%.
All this seems to have started since I purchased the new micro USB lead to get the phone to connect to a computer, However I have since thrown out the other cable and the bin men have taken it.
Just stuck now - I intend to leave it on charge all night to see what happens in the morning, but seriously thinking I never got this X10 now which is a shame as it looks great.
I will probably ring Sony tomorrow only to be told its because it needs to be an official Sony lead which my response will be if I knew the phone was so picky I wouldn't of got it.
Wish I never got the x10 now
does anyone know if sony will take in my phone for repair as I moved and cant find the receipt it has the numbers 10W09 Which im told is 2010 week 9 which will mean I have got until the end of feb 2012 for the warranty, would sony use this or would they insist on a receipt.
