Bluetooth itself uses virtually no energy (~10mw). If it gets hot using Bluetooth there is an energy-hungry app that is using Bluetooth. For example, if you have CarPlay in your car and you are using a nav app it is the nave app using energy, not the Bluetooth connection. Similarly, if you are streaming video over Bluetooth.
