!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.

The phone sends signal, that signal is sent regardless of the audio level request at the other end so the signal costs no extra energy to send.
The headphones at the other end use no extra battery from reading and interpreting the signal at different volumes.
But the energy required to make the speaker vibrate at higher rates takes more energy so the volume effects battery life.
Volume would be speaker amplitude not rates.
Higher amplitude at same frequency can only be achieved by higher rate of displacement change.
Potato, potahto. For an ELI5 it works well.
What everyone says here make sense. But, using audio jack does use more battery, right?
Yup, in this case the phone sends out an analog signal, and must increase the amplitude of the signal to increase the volume, which needs more energy.
Phone battery=no. Wireless audio accessories like earbuds=yes. Changing digit values vs pumping air.
If you make your car receiver louder, do they need to pump more energy at the radio station's antennae?
—Dont hold me in Suspense—
Not sure if you were serious, but I believe they meant, if you turn the volume up on your phone, the cell signal doesn't get worse.
The end device receives the same signal, then uses its own energy to broadcast it at whatever volume
Alright now riddle me this, do you burn more calories if you listen to loud sounds or quiet sounds?
Unlike if you inhale cold /luke warm/ hot vegetables one hurts your ears more than the other
chooses Luke warm
Burns calories... But tastes delicious.
I'm one of those weird people that drinks cold water because it makes me burn more calories and im lazy... Or maybe I just like cold water more really.
No. The signal remains the same except from the bits that control the volume
Would there be a stream of data indicating a volume setting? Or rather a once off "volume up" or "volume down" signal? My guess would be the latter but I might be wrong.
It's the latter for all of the Bluetooth audio protocols that I've worked with.
Actually it's a little bit of both. Some devices use an an audio stream that is encoded kind of like a normal digital audio signal where the bits go up in the encoded audio when you turn up the volume and so does the output. Other devices send a full level audio signal and send a separate control signal which tells the device to turn the volume up or down. If you push the volume button on the receiver and it shows the volume on the source (your phone) going up or down in sync with it, then it's the latter.
It doesn't matter. Even if it were constantly streaming the current volume level, the energy to transmit the value "100" is the same as to transmit "5", so your phone doesn't drain any faster to constantly tell the earbuds the volume is high versus low.
Obviously.
This is a great question because if you're not familiar with wireless communication, it does make sense
