The 4K model of this device has a battery life of up to 10 hours, depending on the working that the device is performing. Streaming an HD video is a resource intensive process, even though it is not 4K resolution, so 6 hours of battery life while streaming an HD movie would be considered within the normal range. With regard to running hot, this is a high performance system. The normal operating temperature range for this device is 100 to 150-degrees Fahrenheit. Streaming a movie would be a resource intensive process and would push the device to the higher end of the normal temperature range, approaching 150-degrees. This would cause the fan to run to keep the system within normal temperature range. If you feel this device is running hotter than 150-degrees, we suggest you take the device in to your local Best Buy and have the Geek Squad evaluate the system under stress.
