I was in my car coming home from visiting the Family for Thanksgiving and I went to check the NAV and my phone was dead! It had been on the charger for most of the day and only off the charger for an hour or so and it died on me! It would not turn on nor would it show that it was charging (the LED light next to the charge portal). I pulled the battery and it came right on and showed battery life. Does anyone know why this happened??
