Does playing audio at a high volume bluetooth wirelessly use more phone battery power than lower volume or are equidraining?

  If you make your car receiver louder, do they need to pump more energy at the radio station’s antennae?

      Not sure if you were serious, but I believe he meant, if you turn the volume up on your phone, the cell signal doesn’t get worse.

      The end device receives the same signal, than uses its own energy to broadcast it at whatever volume

  No. The signal remains the same except from the bits that control the volume

    Would there be a stream of data indicating a volume setting? Or rather a once off “volume up” or “volume down” signal? My guess would be the latter but I might be wrong.

      Actually it’s a little bit of both. Some devices use an an audio stream that is encoded kind of like a normal digital audio signal where the bits go up in the encoded audio and so does the output. Other devices send a full level audio signal and send a separate control signal which tells the device to turn the volume up or down. If you push the volume button on the receiver and it shows the volume on the source (your phone) going up or down in sync with it, then it’s the latter.

      It’s the latter for all of the Bluetooth audio protocols that I’ve worked with.

      It doesn’t matter. Even if it were constantly streaming the current volume level, the energy to transmit the value “100” is the same as to transmit “5”, so your phone doesn’t drain any faster to constantly tell the earbuds the volume is high versus low.

  This is a great question because if you’re not familiar with wireless communication, it does make sense

  What everyone says here make sense. But, using audio jack does use more battery, right?

    Yup, in this case the phone sends out an analog signal, and must increase the amplitude of the signal to increase the volume, which needs more energy.
