On laptops, one of the most common settings to save battery power is to set the power of the wife receiver to the minimum.
For my limited experience, it seems to me that this is not possible on android devices, since I cannot find a single app for that.
In case I am wrong, could anyone please point me to the right app / setting?
Thank you

its probably possible im not sure do some reasearch on the wifi attenas used b/c i'm almost positive it would be possible to turn down but most of these phones have problems connecting wifi as it is turning it down would just make it worse for some might as well just kill it like everyone does! notifications power widgets are the best way!

Most of the times I am using WIFI at home, where my router is set at 6% of its power
and I get excellent signal everywhere with phone and laptop.
I reckon that I could compensate for the reduced power of the receiver on the phone by increasing the signal on the router....
So I guess it really depends on the situation....
But for sure being able to set the power of my receiver would be a more than welcome option for battery saving and not only....
You can't reduce power of a receiver because it's at a set level. Receivers don't draw much power, but transmitters do. If the transmitter circuitry was designed to be easily variable, then an app could vary the output if it was written for that chipset.
If you want to use less power then park yourself next to the cell tower and/or access point. It's just like in real life. If A receives a low transmitting signal from B, then A is going to turn up it's transmitting power to high when it is A's turn to transmit.
Another example is if you and your friend are within two feet of each other and it's quiet around you, then you speak in a normal to below normal loudness in your voice. Now your friend walks outside and goes maybe 200 feet away from you, that same loudness of voice used previously isn't enough for the other person to hear you. You yell. Your friend has to try and listen harder to hear you and he automatically yells back to you.
I know this is an over simplified example and it doesn't always work like that with radio transmitters and receivers. This is just an example without getting too overly technical. You can turn down a receiver but that would be like putting earplugs in your ears. You don't hear as well.
That is why i said that I would increase the power of my wifi router at home to compensate for lower power on the phone receiver ...
Anyway, let's close it here

As with any AT&T phone on the edge network, I get terrible feedback in my car speakers unless I have the phone on airplane mode. Can anyone offer any profound advice?
Thanks!
It's not really feedback but radio interference. It should only be a problem if the phone is within a few inches of one of the speaker lines or audio lines for your stereo. It could also be a fault in the wiring of your stereo that is making it vulnerable to radio interference.
None of my phones past or present have interfered with my car's stereo.

You can put a anti-static bag underneath the phone. It might reduce your signal, but it'll almost eliminate the feedback.

Okay, cool, I just bought one.
Also: the problem only occurs once I actually plug the phone into the stereo. When it is not plugged in, I don't get feedback. Does this mean anything?
Try Unplugging the power
I get feedback in speakers if the headphone jack is plugged into something on the same power strip as the power supply for the phone. Try unplugging a charger and see if it's better.

Thanks, but this is my car.
Feed back is unavoidable if your phone is on 2G only. 3G will completely eliminate this issue but that may not be an option to you if you're only in 2G area. Back in the dark days of 2G service, I can predict a phone call is incoming when my car speaker sounds off the feedback.
I fixed this by purchasing an Anti-Static Bag and placing the phone on top of it.

Those were the good ole days. I can still do that with my girlfriend on her iPhone 3GS. She doesn't have 3G in her neighborhood so its a dead give away when she's texting while on the phone with me.

Is this happening to anyone else? It's been doing it for weeks and I'm positive it's the phone. I always instinctively put my phone down next to my speakers on my computer desk and it will start to static randomly and I'll have to move the phone away from the speakers. It's the same with my Xbox microphone and my clock radio.
Magnets are bad for electronics.. You should probably keep your phone away from them... Also if you do it while your on the phone and the speakers or mic is on your most likely getting feedback

Yeah, I can't put my Charge down on my nightstand because my clock radio speaker starts making some strange noises. That seems to be the only thing that is getting interference so far (for me.)
Does the noise sound something like this?

Interference from the 4G radio...nuff said. Turn it to CDMA only and it goes away.
Sent from my Droid Charge running Humble 1.4
Assuming what you're hearing is like the noise in my post above, here's some background: so-called "GSM buzz" is something that's been inherent to GSM networks for a long time, and anyone with AT&T or T-Mobile had just had to live with it. CDMA, running on very different frequencies, fortunately doesn't have the problem... but it seems LTE, which uses spectrum closer to GSM, may.
Some people have found that placing their phone on aluminum foil alleviates the issue, and some have found like putting ferrite bead magnets on their speaker cables (http://www.engadget.com/2008/08/02/killing-your-phones-gsm-buzz-with-ferrite-beads/).
Yep, mine does. I usually use a cassette adapter to listen to music on my car stereo, but it's almost completely unusable with the Charge. It also makes my computer speakers go crazy sometimes.
It's somewhat like the GSM buzz, but much lower pitched. Doesn't have the same pattern either.
As others have said, it is the LTE radio. Turning 4G off eliminates the problem. Sometimes 3G isn't fast enough to stream my music, though...

Sometimes it happens when my alarm clock goes off since I keep my phone by it. As vash1053 says, it is lower pitched, and in my case it is also more a continuous sound instead of the intermittent blips like in that clip. However, it doesn't do it all the time and seemed to happen more often when I was using the Thunderbolt. In fact, I didn't even make the connection to the phone until I saw this thread; I just assumed the alarm clock was going bad. I will have to experiment more, but I suspect it only happens when data is being transferred. This would explain why it happened more with the TB since it had loads of carrier-installed apps using data in the background; much worse than the DC.
Trying to pair my phone up with a car stereo to play music, but if im over a couple feet away the music completely cuts out.
I seem to remember seeing a 'low power' setting enabled on my phone for bluetooth, but I can't find it right now, and I can't find the way to disable it.
I looked and looked and I can't find it...HTC site is no help either...the Bluetooth power is most likely set very low because of the very aggressive power management the HOC has....the vivid battery was horrible and people complained so i think HTC listened and employed the very aggressive power management...probably why I get about 26 hrs on a charge...I like it all but the multitasking issue...

I'm curious if anyone else is having this issue or can confirm this is happening on their phone.
I'm pairing my phone up to a bluetooth car stereo (4 different ones) and a couple bluetooth sound docks, and the result is the same no matter what.
If I walk more than a couple feed away the music cuts in and out. it completely disconnects at around 12 feet.
I have never seen bluetooth range this poor, even on my cheepo chinese bluetooth adapter a coulpe years ago.
I called HTC and their only options were telling me to factory reset my phone.
I believe it is by design as part of HTC's "aggressive" power management...I have tried to find a way to increase the Bluetooth power but have not been successful...I have to be no more than 2 feet or so for mine to work..I'm sure there is a way to increase bt power but I'm not sure how...I think I remember seeing this in another thread..
Sent from my HTC One X using xda premium
^It was probably my first thread.
I'm assuming the reason the range is so bad is because the phone is running in low power mode, a feature of bluetooth 4.0.
Yeah, BT 4.0's main attraction is the low power usage. You can't have both great range (the old BT devices) and great battery life. Given a choice, I'd prefer great battery life.

Bluetooth 4.0 is multiple standards of bluetooth plus a low power version.
It should have better range than bluetooth 2.0, but with the added ability of a low range/low power mode.
The audio will cut in and out even if the phone is just in my pocket and I am using a bluetooth headset (Motorola Elite Sliver). If I cant find a way to fix this or it doesn't work with a different headset I am not gonna be able to keep this phone. I really like the device but the non-existent multitasking and the terrible bluetooth performance is pushing me away. When I work I use my bluetooth all day for either customer calls or just to listen to music/radio on down time and I can't deal with this for too much longer. I'd hate to go back to my iPhone but I may have to unfortunately..
pretty disappointed.
I'm also out of my return policy on this phone now, and they have no other good phones.
Hopefully htc comes out with a fix for this soon.
I've called them 3 times now and havn't gotten a single good answer to why its so bad.
Also emailed them and still no response.
I have also noticed poor range. Much less range when streaming Bluetooth audio to my LG soundbar compared to my iPad and buddies iPhone.

If my headset is on one ear, but the phone's in the opposite side's pocket. It cuts out.

hey guys, i just bought a One X and im having similar issues. there should be no excuses to have bluetooth cutting out like this on a new phone. My old Desire HD did it and i just thought it was because i had dropped it, but looks like its a HTC thing!

I have no problem at all anywhere in my car, I listen music and radio an average 40 mins a day (while comute). I have a bluelogic bt that came built-in the car.
I also haveno problems and no cutoffs on my stereo bt headphones and I often leave my phone on the table while I workout (true, under 10 feet away). If that matters, I'm on 2.20 stock.

Same here
i never used bluetooth with my ONE S before now. But I have moved it in to take over my business phone needs and replace my Sensation 4g. It is definately worse range. And if it it 10-15 ft away on the hood of my truck and i turn my headset away from the phone, the signal from my phone can't carry through my head. The sensation had no problems. The newer plantronics headsets are worse than the older ones as well. And putting the phone in my work belt on the opposite side from the earpiece is really bad. I don't know what to do. Might be time to fix my sensation and move back to an old headset.
When I use a wired headset, people are hearing themselves echo back. I'm running moar Rom, but I'm not sure if its related to the Rom. I've used the original headset and several aftermarket headsets with the same results. When the headset is disconnected, the conversation goes back to normal. I don't here the echo on my end. Anybody else have this problem with the s5?

Anyone?? Blue tooth works fine. All my wired headsets are echoing back to the person on the other end of the line. I found out that its not the Rom, by loading the stock Rom back on the phone, with the same results. This leads me to belief that its a hardware problem with the headset jack, possibly.

An update on my wired headphone echo problem. I think I can trace it to the volume level. If my volume level is set to high, the person on the other end gets the echo. It happens with every wired headset that I have. I'm not sure if its leakage occurring within the phone or the headset. My suspicions are the headset wires don't have any shielding between the Mic and speaker wires. Its either there or within the phone itself. When I turn down the volume the problem goes away for the person on the other end. Bluetooth works fine.

This was exactly the solution I needed for both wired and speakerphone usage, and just wanted to post to let you know how appreciative I am of your self-resolved solo-thread! There are many similar complaints all over the net about the S2's echo problem--with numerous nonsensical fixes and/or warranty-voiding solutions, but nothing remotely helpful regarding the S5. Of all the solutions I came across, not one person mentioned simply turning down the volume!
As a previous owner of the S2, I never had any of the troubles stated by many users, partially because the ICS OS was so clean and easy to optimize. The S5 is another matter entirely; after countless hours and days of immersion in KitKat, I had no clue what of the million one Touchwiz bloatware apps and options was the culprit. Or if it was just a hardware flaw. There was no way in hell I was going to get a replacement for a mere echo since too many hours were already sunk into reconfiguring and installing backed up applications (for a second time), and I was already using a hard-won replacement due to some bizarre problem where the original phone bricked itself.
Nevertheless, the echo wasn't an issue at all at the beginning, but after optimizing and customizing ad nauseam, I gradually discovered that call quality was never consistent for my wired handset, wired headset, wired headphones, a splitter setup, and with the speakerphone. Sometimes others complained, other times they didn't. And after a while--where circumstances forced me to keep the volume setting on maximum all the time, the echo problem, along with a deluge of relevant complaints, became a constant whenever the phone wasn't radiating my head. (Despite the current "safe" SAR info out there, this S5 model is still dangerously high for me as my face will experience numbness when pressed up against the device for extended talk time .)
With the sheer amount variables to test, the prospect of bothering others to double check call quality, and the added frustration of communication-imposed radiation, this simple conclusion would have taken me a long time to resolve on my own.
Many thanks for posting!

The solution is to turn down the volume? Nice free solution brother! This has been driving my wife and I nuts whenever I am driving in Chicago (hands free or ticket, land) using my wired headset. the only downside is my hearing isn't what it used to be...dare I say I may need to go iPhone if Galaxy doesn't get their act straight. Hmmm, I wonder if this issue has been noticed and fixed on the Edge? Thanks again for the only REAL solution I can find on the web.
Echo in headphones~
Another thing to try might me to put your phone in TTY VCO mode. I find the echo goes away and you can keep your volume as well. Let me know if that works for you.
I know this an old thread, but I *just* started having this problem. The earbuds that came with my phone don't have this issue, but one side just quit working so I ordered new earbuds... I have ordered and returned 2 sets of random earbuds, so I finally ordered the OEM earbuds, assuming they would work (since my original ones do). Just got them today and the person on the other end can hear themselves. It's so strange. How is it that 3 pairs of earbuds produce the same issue, yet the original ones work fine (except for the fact that I can now hear out of only one side)?!?
Since the new OEM earbuds didn't solve my problem, I started looking online for a solution. I am a freelance web developer and have to talk to multiple clients regularly and it's nice to be able to have my hands free since I usually need to be on my computer/their website when speaking with them. This is so frustrating -- I just turned off the noise isolation function, I will try turning down the call volume.
Thanks for the suggestion @Xalky
