Answers to some of your questions about your Battery Status
Why does my Battery Status say Overheat or Over Voltage?
You may be using a charger that is not compatible with your Samsung Galaxy S III® or your phone may be using a lot of resources.
Note: You risk severe damage to your phone if your charger isn't the same voltage, amperage, and plug type as your original charger. You can purchase compatible chargers on sprint.com.
