Which uses more energy (battery), Bluetooth or self-contained speakers?

Asked by Strauss (23950points) September 6th, 2021

Scenario: Suppose my Bluetooth-enabled Android phone has a charge of 30%, and I am not able to charge it anytime soon. I also have a Bluetooth speaker which is fully charged. Will I use more energy streaming music directly through my Android’s self-contained speakers or through the Bluetooth?
