minus-squareAussiemandeus@aussie.zonelinkfedilinkarrow-up94arrow-down1·3 days agoThe 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.
