The phone sends signal, that signal is sent regardless of the audio level request at the other end so the signal costs no extra energy to send.
The headphones at the other end use no extra battery from reading and interpreting the signal at different volumes.
But the energy required to make the speaker vibrate at higher rates takes more energy so the volume effects battery life.
Volume would be speaker amplitude not rates.
Potato, potahto. For an ELI5 it works well.
Phone battery=no. Wireless audio accessories like earbuds=yes. Changing digit values vs pumping air.
If you make your car receiver louder, do they need to pump more energy at the radio station’s antennae?
—Dont hold me in Suspense—
Not sure if you were serious, but I believe they meant, if you turn the volume up on your phone, the cell signal doesn’t get worse.
The end device receives the same signal, then uses its own energy to broadcast it at whatever volume
Alright now riddle me this, do you burn more calories if you listen to loud sounds or quiet sounds?
Unlike if you inhale cold /luke warm/ hot vegetables one hurts your ears more than the other
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.
It’s the latter for all of the Bluetooth audio protocols that I’ve worked with.
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 when you turn up the volume 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 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.
Obviously.
This is a great question because if you’re not familiar with wireless communication, it does make sense
