Any body with an X10 that shuts down at random, problem powering back up etc etc? well i have just solved the problem on my X10. After countless re installs / factory resets which did not work i checked out the battery and the pins that go up against the battery. Bit sticky, so cleaned off and just to be sure put two little drops of solder onto each terminal plate on the battery so that the pins would make contact better. Hey presto. I can throw the phone around the room and it refuses to power off. This may well have been the problem that made my original battery drain too quickly. Don't know if this helps anyone else, but did the trick for me.
