[Q] Battery life of bluetooth vs aux cable - T-Mobile, Samsung Galaxy SIII

I tried to find info on this and found little peices here and there but wanted to get a clearer answer. I was wondering if anyone knows what draws more power from my phone. When playing music does it draw more power to play music through an aux cable at full volume, or through bluetooth. I would think that bluetooth would not require as much power but I'm not sure. This is the ultimate geek forum so I trust your answers Thanks!

Bluetooth would use more power because its having to broadcast the signal for the receiver. Over an auxiliary cable its just sending the signal and nothing else. Just like if you were listening on a pair of headphones.
Listening to music over a Bluetooth headset would use more power than listening over headphones.

two way communication
I think it should be other way round as now Bluetooth 5.0 has more power saving features and it detects if the music player / headphone is just with a speaker or with a mic too ( as mic will make it two way communication) and the headphones lead draws power for the current. Not sure, if someone can throw some light on this. many thanks.

Bluetooth reciever for sending Audio to Hifi?

Hi,
I have a HTC Touch which I am currently using the Pocket Player software to stream my music from my PC which is located upstairs. I can connect the Touch to my Stereo amplifier through a USB/Jack cable and play the music through my Hifi speakers rather than headphones but I was wondering if it would be possible for me to transmit the audio to my amplifier by way of Bluetooth. It would cerntainly allow me the freedom of changing tracks on my phone sitting in my armchair rather than sat next to my amplifier through a cable. I.E Streaming music from my PC through Wi-FI, via my HTC Touch through bluetooth.
Hope this makes sense. Has anyone done it and is there a noticible difference in sound quality when sending music by bluetooth rather than a wired connection.
I have seen various Bluetooth type devices on ebay and amazon that claim to do this type of thing but as I have never tried Bluetooth I am a little sceptical and not sure exactly what is required. I assume that as my Touch can send Bluetooth beam I would only need a reciever to connect the Jack plug from my amp, is this correct? Or would it be better to buy a jack transmitter/receiver for the job.
I don't want to spend a whole lot of money doing this just to test so can anyone recomend a device.
Thanks in advance for any help.

Music Through Car Stereo

I just bought a new car yesterday & have a question about playing music through the stereo. My car is a equipped with a 3.5mm & a USB. Basically it is setup so that you can play your ipod/iphone through the car stereo.
I can play music from my phone using the 3.5mm AUX but there is not a lot of volume. Not only that but the quality seem to be degraded.
I can connect my phone via the sync cable but music will only play when I select disk drive when asked for the usb connection type. The sound quality & volume is excellent but I can't use my playlists on the phone. Is there a way to get music to play through the car stereo when activesync connection is selected?
Or is there a cable like the iphone cable that will allow me to do this?
How good are you with wiring? Their are pretty easy to install car kits that will work better

If you check the manual for the stereo system, are there any playlist formats that it does support?
Perhaps just by saving your playlists in a different format, you might get it to work...
normally in my stereo which only has the 3.5mm headphone jack I find that if you turn the phone all the way it up sounds very distorted, I tend to turn it down 2 notches from max and adjust my car stereo volume from there
i also found that to be very helpful with quality also
Update:
My car stereo will read the folders on my imagio when disk drive is selected for the USB connection. I can scroll to individual folders & songs that I want to hear. There are still too problems though.
1. I would rather navigate my music folders via the phone with an activesync connection.
2. When I have the disk drive connection selected I am unable to use TomTom.
I can use the AUX jack but I don't get as much volume. On the highway at 75MPH I have to have the volume on the stereo maxed & it still isn't loud enough.
Is there a solution that would allow me to use the USB connection?
I would prefer a solution that is only going to cost me a couple of bucks
Previously I did have one of the FM modulators to play music through the stereo. I am aware of lowering the volume on the phone to reduce the noise.
Thanks to those of you that have replied to my original post.
It looks like your phone doesn't have enough "power" to feed your AUX in.
Normaly you should use a line-signal to feed your AUX.
What you can try is to amplify your signal from you phone before you send it in you AUX.
If your car stereo have a bluetooth option, you can pair it for sound!

VZW Nexus headphone recognition - App for that?

Not sure where or what to search for on this issue but it's been killing me with my Nexus for the past few months.
Coming from a couple of HTC phones one thing I really liked about them, which might have been Sense feature, was the phone having two completely separate audio volumes one for when headphones were plugged in and another for when the phone was hooked up via Bluetooth.
My problem is I listen to music very low with headphones at work, then unplug them before getting into my truck, automatically hooking up to the Bluetooth to stream and the volume stays at the low headphone volume. To hear it over truck stereo I need to turn the phone BT volume all the way up. Fast forward to when I sit back down at work to listen to music, my headphone volume is back to the last BT volume or maxed out. Just a real annoyance and find it hard to believe this is the way Google designed it and has nothing in place when I'm having an off day and don't manually fix it before I listen to my headphones again and blast my eardrums like I did yesterday.
Is this how the Nexus should handle BT and Headphone volumes? Is there any kind of fix for this?
Thanks in advance

Recs for non in ear headphones with mic and controls

I like the sound of the stock headphones but looking for a pair that aren't in ear but still have a mic and controls. Looks like I might have to go with bluetooth, but would appreciate any suggestions.
You could always use something like this:
http://www.amazon.com/Headset-Adapt...&sr=1-60&keywords=wired+microphone+3.5mm+jack
There are several out on the market if you look around. Some have controls others only a microphone.
The advantage would be that you could use any headphones you like or already have.
Problem is that you have to find one that works with the S3 which seems to be a little picky when it comes to wired controls. Especially the control part like volume up/down and skip tracks. The answer call button usually works as does the microphone. But you'd have that same problem with a Headphone with included controls and there are not many of those out there.
A bluetooth transmitter with controls would have the same advantage of being able to choose whatever headphone you like but the hassle of having to pair it, the diminished battery life of your phone aswell as having to keep track on the battery charge of two devices makes bluetooth an unattractive solution in my opinion.

very low Bluetooth volume output

I have noticed that when either connected to Bluetooth headphones or streaming to my car stereo that I am having to turn the volume up to nearly 90% just to get a reasonable volume.
Any work around for this ?

Yea I have a pair of wireless beatsx, but those headphones are junk anyway. Can not get them "loud". Maybe its the phone/bluetooth..
I noticed the same thing when I first paired the 7t with my car's BT. I don't consider it a problem because all I had to do was raise the volume on the car radio, and it remembered the setting. But I'm only listening to navigation prompts and voice phone calls. I haven't tried it with music.
Anyone solved this problem?
While using headphones or any audio-bt devices connected to oneplus 7t i can get only around 70-80% of max device volume.
My bluetooth can get painfully loud on any system... Are you sure you are not facing to sets of volume controls?
Some "dumb" headphones / speakers just have one output volume and you control loudness via the phone volume. Others have their own volume processing (like a car stereo). If you max out your phone volume then you can control the loudness via the stereo.
Numerous times I've been in the car and can't figure out why I need to turn the stereo volume up so high only to realize I've bumped the phone volume to a low setting.
