Check usage

It is possible phones will become warmer during heavy use.

This is normal behavior especially if you are transmitting data, talking for an extended period of time, using GPS navigation or playing games, music or videos on the device.

In these conditions, the phone is transmitting and utilizing alot of power on the device which will generate heat.

Tips:

• If you are feeling the warmth from the front of the screen verify the display settings. It is not unusual for the display to become warm when in use for long periods of time.
• If you are feeling the warmth from the back of the phone it could be a sign that an application is running or there is a problem with the charge

Some facts on battery temperature

• Devices need their space; There are no on-board fans, cooling relies solely on the device being able to dissipate heat through the air. To help cooling, ensure the device is not in a pocket, purse, carrying case, or direct sunlight.
• Normal temperature is (97f) ~36c
• A user will begin to sense a “warm” device at 106f (~41c) and it will seem hot at 109f (~43c)
• Cool Down Mode kicks in at 152f (67c)
• Batteries with temps => 113f to 140f (45c to 60c) will not charge to 100% capacity
• Battery temps >140f (60c)will not charge at all
