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?

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
This is a great question because if you’re not familiar with wireless communication, it does make sense
No. The signal remains the same except from the bits that control the volume
