I'm having some major problems charging my x10 at the moment! I went home to see the family over Christmas but accidentally forgot the charger plug (USB adapter) for my phone, so I now only have the USB lead. A few weeks back I had to return my phone because the battery was not charging properly after one morning I woke up and my phone was on red hot and about 6% charge (despite being on charge all night) The phone was returned to me with a new battery, stating that this was the problem. But I have a question: Why does it take so long to charge on USB? I may be able to answer my own question but my theory is it because it is not a direct current? But even so, does 12 hours for it to go from 5% to about 20% on a USB charge sound a little extreme? (this is with the phone OFF!) Also, I charged the phone earlier and on one of my last checks it was on around 60% - this is charging with the phone on - but literally 20 minutes later my LED was red and the battery was down to 8%! What on earth is going on with this phone?! Any help would be great.
