Why does the back of the Kindle Fire get hot?

The back of a Kindle Fire can get hot due to several factors, including prolonged usage, intensive tasks like gaming or streaming, or charging the device. Heat is generated by the processor and battery during these operations. Additionally, inadequate ventilation or using the device while it's covered or in a case can trap heat. If the device becomes excessively hot, it's advisable to give it a break to cool down.
