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'd do some experiments - fully charge the phone, set it to play the same
multi-hour podcast, come back at the end and see what the battery percentage
looks like.

Remember to repeat the experiment sufficiently for a statistically
meaningful result ;)
