Got a W595 December 2008, worked great till about July last year when it stopped working, or at least it stopped charging and taking it to a store they said it had condensation as the metal pins were a bit green/mouldy.
I got another Sony Ericsson phone around December 2009 which had the same battery and charger as older phone so found my old charger and battery to be working as well as my old phone just not charging.
But my newer phone has been having issues in the last month, strange ones actually as it wouldnt charge at all in one of my wall sockets but worked ok in another with both chargers, then on the same socket on another attempt it started charging but the battery lasted a day before dying so maybe its a wall socket issue?
Finally I went on holiday and left my chargers at home so bought a travel charger, it didnt work so assumed I had a dud charger, but took my phone to a 3 store to be certain and their charger didnt work but as soon as I got home from holiday the phone charged right away on my original charger! and then suddenly the travel charger worked!
I just find it strange how I have had 2 tempermental Sony phones in a year with pretty much the same issues with charger socket.
So are they built bad or is it just they make charger sockets bad or something else.
