I have been using my X3 since the early days of it's release. The device has never run hot on me before, until about a week ago. It was on my desk and when I picked it up it was very warm. The back was warm as well as the glass on the front. The battery was also run down from a full charge to about 40% in only about 5 or 6 hours. Today, the same thing happened. Picked it up and the case and glass was shockingly warm. Checked the running apps and nothing really stood out. Outlook, podcast, Skype Preview and phone dialer. Turned it off and temperature seemed to be increasing even with it off. I let it sit a minute or two, then rebooted and it started to cool down. Battery level went to 40s again on about 6 hours since full charge. I'm suspecting Skype Preview might be running the processor in a loop but I'm really not sure. Anyone else having any similar problems? (I'm running the released OS, not Insider)
