Put my phone on the charger and then fell asleep for about 90 minutes. Once I woke up I went to get the phone and the green light was not on indicating a full charge and the phone would not wake up. I can pull the battery and reinstall it but it still doesn't wake up until pushing the top button maybe 6 or 7 times or so and then it reboots. But then it will still completely lock up and die again in a few minutes. Is there such a thing as overcharging these phones that causes them to die?
