#143743 — Which uses less power

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?

Any idea?

Too marginal to say definitively. It might make a difference if you
routinely turn off BT when using the internal speaker, but most people
don't. 

The best way to save power is use airplane mode which turns off the mobile
radio.

But no cellular radio (for data aka Internet) means no podcast.  The OP
isn't listening to local audio files on his phone.  He is listening to a
podcast, and that requires Internet access which requires the cellular
radio for data.  I suppose he could be using an app to first download a
podcast to save to a local file on his phone, but he didn't mention how
is is listening to the podcast: locally downloaded file, or streaming
from Internet.

  I haven't used podcasts in a while, but when I still did, downloading
(in MP3 format) was the normal way, i.e. not streaming and no Internet
needed to play.

  Wikipedia implies that's still the case:

'Podcast'
<https://en.wikipedia.org/wiki/Podcast>

"A podcast is a program made available in digital format for download
 over the Internet."

With mobile internet plans being that cheap nowadays I usually just
stream because it is only going to be a few MB anyway. 
I use Podcast Addict (paid version, 10 Euros/year), with this app you
can of course do both.

Not if you use any regular podcast application for mobile phones.

https://independentpodcast.network/training/what-is-the-difference-between-podcast-streams-and-downloads/

Yep, the OP didn't specify how his listens to them.  I used to listen to
podcasts, but I did not retain them.  I had no want for a local library
of podcasts, or to repurpose the content.  Retention was not a goal, for
me, so I didn't need to waste storage space on a podcast that would
never be re-listened.  I don't hoard media.  Some folks do.  Different
goals for different folks.  

Downloading affords listening where streaming is not available, but
podcasts, to me, are very nonessential, and usually very uncondensed (to
long to get the info).  If I'm out in the boonies camping or hiking, I'm
not ruining the ambience with noise from my phone which is likley turned
off, anyway; i.e., I unplug.  I can entertain myself in other ways, or
just snooze on a long trip, or think through projects or resolutions to
problems or make plans while idle.  An issue of Scientific American will
occupy me during both flights for a vacation, and beyond, and I don't
need to download anything, have an Internet connection, or even need
power.  I certainly don't want to be a driver distracted by a podcast.
Unless someone else is in the car, I rarely turn on my car's radio.  I
don't watch movies on a flight even if free.  I prefer less noise and
less distraction.  

Podcasts never seemed an efficient means to convey non-fictional
information.  I don't do fiction.  If I want an audio distraction during
a long trip, it'll be music, and using noise cancelling over-the-ear
headphones: I want to hear the music, not the noise around me.

Even with unlimited data, I never bothered to check which method
(download vs streaming) for podcasts consumed more or less bandwidth.
Podcasts were a short-lived fad with me: lots of noise, too little
information, and too slow to get the information.  To me, podcasts
seemed a waste of time, or noisy low-grade content during idle time.
But that's me.  It's one of those things I tried, eh, but not great.

Podcast listenership is generally still growing, but I'm not drawn to
the fad.  I'm also not into Zoom, Skype, Google Meet, WhatsApp, Teams,
Signal, either, nor into social sites (aka sites for the socially
needy).  

https://www.pewresearch.org/journalism/fact-sheet/audio-and-podcasting/

I didn't find a fact sheet comparing usage of download versus streaming
for podcasts, but I didn't look very hard.  Not a topic of interest to
me.

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.

I only use earphones when I must use them (when around other people).
Otherwise I greatly prefer my sound to arrive at my ears the natural way.

I have a choice of bluetooth speakers (which have their own power).
Or the phone's speakers (which use up the phone power, of course).

Both use the phone's power to make sound but for different reasons.

The phone has to output to the bluetooth speakers over bluetooth RF.
And the phone has to output to the phone's speakers using audio power.

I wondered which is more efficient for the phone because on long waits,
such as those in airports, train stations, bus stops, and uber stops, you
often do not have easy access to USB power in the waiting spot you're at.

It seems from what one person wrote that the speakers consume much more of
the phone's power but from another reference it seems it's not so much.

It's confusing what the answer is where the reason for the question is that
the phone only has so much power on long trips where there is often a
series of long isolated waiting periods in between transportation types
where you're all alone but nowhere near USB chargers so you listen to
podcasts (whether on cellular data, wifi or not depending on availability).

I asked the question focusing only on the phone power requirements delta
between casting audio over bluetooth versus directly powering 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.

https://www.newegg.com/p/pl?d=ble+speaker

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.

https://www.amazon.com/POW-Expandable-Wireless-Universal-Compatible/dp/B07NWV79L9
(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:

https://www.ebay.com/itm/404233152689?chn=ps

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.

https://youtu.be/d-LpPcO0VL4?t=247
https://www.youtube.com/watch?v=5RM_rdw9X0A

Reminds me of the Red Green Show - but wait, no duct tape.
https://www.youtube.com/watch?v=NWzPCLcbExo

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.

It's just a podcast. Audio quality isn't a major concern.

The concern is there are often long periods of isolated boredom when
traveling on long trips where there are often benches or corners where you
wait for some type of scheduled transportation to arrive but which you
can't easily schedule because you have no control over arrivals/departures.

During those long waiting periods you may or may not have access to USB
power and you may or may not have access to the Internet so the question
was asked without adding those two complexities into the problem set.

Generally I download a few podcasts (just in case) and stream otherwise, 
but as I said, you can't be assured of an Internet connection at all times.

Given those constraints, the question was only about the power delta
between spitting out audio from the phone speaker versus via casting that
audio to a separate bluetooth speaker (which is independently powered).

With the equipment that I own, my hand-held bluetooth speaker is louder but
it's a PITA to carry around and ensure that it's always charged up by USB.

I had thought the phone's speaker would be MUCH MORE power hungry though,
than casting the audio to the bluetooth speaker - but one respondent said
it was NOT more efficient (while another said it was more efficient).

So I'm still not sure.

Depends on whether your phone supports BLE (Bluetooth Low Energy) or the
older traditional BT.  BLE will consume as much power as BT, but sends
in bursts.  Between the bursts the BLE radio is at idle/sleep power
level.  However, there are high-efficiency speakers that can be used in
the phone, and other factors depend how much power the speakers consume,
like volume level.  Ear buds and headsets don't need to use nearly as
much power to generate the same volume as the speakers since they are in
or right atop your ears.  There are a lot of variances in the components
used for the speakers, in the headset, if BLE or BT is used, and even
the capacity of the battery (a lower capacity battery will die faster
under the same load).

As others pointed out, you should measure the difference in battery drop
(starting from a full charge) while testing how much the battery level
drops between when using the speaker, and when using the BT headset.
You could use an app to monitor battery usage by app, like whatever
you're using the play the podcast, or the main battery's drop in power
level.  I would test for, at least, an hour in each mode (speakers only,
and BT/BLE headset only), and probably repeat the test, at least, 5
times to get an average reading.  Recharge to 100% before each test to
start at a known capacity in the phone's battery.  For the BT/BLE
headset, make sure those are also charged 100% before each test when
using them for audio output.  Testing and measuring will let you know
for sure.  You could use an app to measure the battery drop after each
test, and gauge where the power is most consumed, or just watch the
battery level indicator for a rough estimate.

My non-exhaustive research shows that with newer components, and using
BLE with the headseat, and with high-efficiency speakers, the speakers
will draw the same, or maybe a tiny more, than the BLE headset.  Higher
audio volume in the speakers means more power consumed by the phone's
battery, just like higher volume in the headset means more power
consumption on the headset's battery.  

I was in the camp that speakers used more power than BLE headsets, but
the more I read the more they can be [nearly] equal in power consumption
if the latest components are used in the design.  Actual measurement is
more accurate rather than guessing based on specs which can be wildly
exaggerated.  If you have internal SATA-3 drives, HDD or SSD, or even
m.2 NVM3 SSDs in your computer, have you ever reached the theoretical
and marketed 6 Gbps transfer rate, even for burst transfer mode versus
sustained transfer mode?  Marketing cannot be trusted to supply accurate
specifications.

When I used podcasts they were usually downloaded and could be played
any time without a internet connection. That makes them interesting for
longer flights or ship travelling. And many users build libraries of
podcasts.

People should do the same with any media content (video tutorials
 on YouTube, music, movies...)
That's also why real FM radio is better than webradio.

Well - there is no big difference if you download 100 MB as one file or
stream it using HLS with smaller segments. In the end you will download
100 MB data. So only avoiding downloads completely *may* be better for
the environment. But on the other hand using data media like CD/DVD/BD
was also not ideal since these media had to be produced first.

You are right... if you are going to stream it only once.
If you are going to play it several times, streaming gets worst
 than downloading.

There must be few giga free on your private storage. Anyway usb

Indeed. But podcasts are usually only listened once and not repeated on
a regular basis.

My available private storage is around 30 TB in total, distributed over
three servers, two NAS and a number of computers and smartphones ;-)

I wonder how people manage on planes, then?

That's an assumption on your part as the OP said nothing about the source
of the podcasts. Many podcasts are downloaded.

Correct. Either is possible. How does that help with answering the question
at hand?
