Which uses less of the phone's battery power on long trips?
 
Playing long podcasts with the Android speaker as the output?
Playing long podcasts with a Bluetooth speaker as the output instead?

 
My instinct says that moving the speaker coil is going to cost more
power than doing RF for the Bluetooth, but it'll depend on a lot of
things, such as how much volume you have for the speaker.

I vaguely recall observing something like an additional 200 mA drain
when playing my phone speaker at a medium-loud volume. That's quite a
lot.

I rarely use Bluetooth but some say its current consumption is about a
tenth of that, or even less.
