Glad you finally agree.

bluetooth uses a negligible amount of power

With my phone's 3760 mAh battery I generally end the day at over 80% so
whether Bluetooth or wired phones use more juice is pretty much academic
for me anyway. YMMV.

listening to music and certainly having the display on will use a
*lot* more power than bluetooth

You think the display really stays on when listening to music??

I just hit my phone's off/sleep button when the music app is playing
and the screen goes OFF while the music stays ON. SAME when streaming
radio apps. SAME with all my Android and Amazon devices. SAME with my
Chromebook. And likely SAME with Apple stuff. It seems that after all
this digital headphone rhetoric of yours that you don't even use
headphones...
