No you would have to isolate the contact on the plug for the cut off bud and microphone to isolate power like that.
As far as your phone goes it sees in the logic you have 2 earbuds connected and a microphone so it will send power even if nothing is there.
Honestly if you want to save battery just use airplane mode and turn off Bluetooth or get an old iPod or mp3 player.
