Yep, the OP didn't specify how his listens to them.

 
It was a general question where it was about power requirements.
The phone can speak and the phone can throw bluetooth.
Whether or not WiFi is involved wasn't part of the question.
 
On trips, there are long waits, such as those waiting for a ride.
You're sitting on a bench or in a park or at a bus stop or whatever.
 
You want to listen to a podcast (whether streaming or prior downloaded).
I don't like earphones. I don't like earpieces. I like real speakers.

But there are BT speakers, too (although you should check your phone
supports BLE, and, if so, get BLE speakers).  I've NEVER been impressed
with the audio quality out of a phone's internal speaker.  When using a
headset, I get the over-the-ear type with noise cancellation.  I want to
hear the audio from the phone, not around me.  That does mean you may
not hear the approach of the bus, or announcements over the speakers at
the airport.  Of course, that means having to tote around a BLE speaker
to get good sound, and also impinging the ears of others with your
noise, like those insensitive thugs toting around boom boxes to annoy
everyone around them.

If wearing ear buds or headphones is undesirable, use the phone's
speaker, or tote a BLE speaker if you want decent sound without
something in or on your ears.  Even a tiny BLE speaker surpasses the
phone's internal speaker.  You could use the BLE speaker until its
battery goes dead, and then switch to the phone's speaker since the
phone's battery is still alive.

Don't remember the brand and model of my aunt's choice, but it folded
for compact storage (looked like a small folding cup).  When expanded,
it had a lot better bass than the phone's speaker.  Folded the external
speaker was about the thickness of a hockey puck, but much smaller
diameter.  I didn't think much of it until I heard it.  Far superior
than the phone's internal speaker.

(BT 4.2 is a version of BLE)

Not what she had, but gives you an idea of using an external BLE speaker
instead of the chintzy one in the phone.  Hers looked more like:

but hers was cylinderical rather than conical, the the folding sections
slide past each other instead of silicone that crushed.

By the way, to get better sound quality, I've heard that putting the
speaker end of the phone into a cup acts like a passive amplifier and
gives more bass.

Reminds me of the Red Green Show - but wait, no duct tape.

Seems, to me, a passive amplifier just better exemplifies the poor sound
quality of the phone's speaker while a BLE speaker would produce better
sound.  However, with a passive amplifier, you could lower the volume of
the phone's speaker to reduce its power consumption.
