When I plug in my charger into the outlet, I hear a faint hiss; when the charging completes, and when I remove the charger from the outlet, the hiss still persists for some 2-3 seconds. Is this normal?
Mine doesn't, but my wife's htc sensation does & it drives me nuts. I have not figured out a fix either. Tried different cords, chargers, nothing.

I'm actually using a stock charger that I bought from ebay; I don't like opening the new charger that comes with the phone in the box unless it is absolutely necessary. Anyone else hear's the hiss? Almost every forum member posting at the N7100 XDA Forum confirms some form of hissing

I have same problem but only hear the hissing sound when car charging it while using the audio jack. Have you try differnt charger? Is there any magnetic static whatever may think cause your charging sound.

I haven't tried another charger; I do have a 0.7a Samsung Charger lying around somewhere. I will update once I find that charger.

I do t think its normal to make a sound like that. Hey if this problem cannot be fix and you try everything you could then, your only choice is using your insurance if you have one and get it fix. Good luck!

YES I get this problem too and when I notice it, I get really annoyed. I first noticed this about a week ago and I had trouble falling asleep because of it.
It's strange because I read everyone's comments in the N7100 forum on XDA, and they confirm that this is indeed normal because of higher amperage. I can hardly hear the hissing on my charger unless I put my ear next to it. Obviously, I would believe this is normal then. I have an HP laptop which comes with a travel adapter that hisses. As a matter of fact, I have two HP chargers, both do the same hiss, lol.
Also, I get the average current somewhere between 1200 and 1400 milli-amps, and occasionally, the Max amperage that shows on my charger is 1,800. I'm under the impression that the chargers don't provide consistent output. When the phone is switched off, I would believe that the max current is provided. Probably, nothing to worry about then. Though, there seems to be a lot hype over this. Samsung...
I actually have two stock Samsung chargers. They are both 2000 miliampers and they BOTH do that annoying noise. ((((((((
I've confirmed this is normal; the Samsung chargers are rated at 2 amperes; therefore, the hissing sound is present. HOWEVER, if your hissing is so loud that you can hear even from a few feet away, replace it at once, because its an indicator that the capacitors have either gone bad, or there is a wiring issue (similar to a bad circuit board, etc). Minimum hiss like what I'm facing is normal.
Now, coming to the amperage output, I don't get the full 2A current. Samsung is duping their customers. Shame on them. The current fluctuates; it would have been reasonable if Samsung listed a range instead of fixed # for the listed amperes on their stock chargers. I don't see anyone getting full current (even on the N7100 forum).
Something tells me its due to the charger being made in China but made for US... I mean even my electric razor hisses when plugged in lol

Well, if you go here, http://forum.xda-developers.com/showthread.php?t=2112811&page=5
The whole international community is experiencing the same thing like us. I don't think we are the only ones experiencing this.
Perhaps, 'cause it is Made in China.
Either I'm deaf or I just can't hear the hissing lol.

Obviously, some will say as what is mentioned below. Confirming with well over 20 forum members clearly confirms a hiss is present in all chargers. Whatever...

Not sure if anyone else is experiencing this but I have a buzzing sound in my headphones in the left ear. It is fairly loud when the phone is idling. When I switch apps or screens it goes away momentarily then starts again. I have tested it in the music app and it does not appear to be an issue while playing music. I checked some very low volume sources and its not there. Still I wonder if I have a bad unit or have something activated doing this. I am completely stock new AT&T LG G3.
Update: After testing a few more sets of headphones, this only happens on my Bose QC15s which have the noise cancellation. Its interesting though that the Bose are dead silent on my Galaxy S5 and my wifes iphone. I tried both cables with them (since one is designed for idevices) but it doesn't make a difference. Not sure what interference they are picking up but I think I will take them to an AT&T store this weekend and see if it does it on their display models.
Is it anything like...

I think it's the same thing. With the Bose it's like a humming buzzing sound. I don't hear it at all with the Apple $79 IEMs. They are listed at 23ohm impedance. With mine it's as if theorizing switches on and off though. I can switch apps or play music and its dead quiet after I immediately pause but then it clicks back to buzzing.

Same here, Bose QC20 LG G3 D855... Left Channel buzzing.
Do you think it's a defect of the phone?
they all have this problem, let's hope an update

I was almost returning my G3 and i was like "Hell no, again..." , i have exchanged my nexus 5, 5 times! and still has the same problem!
One interesting thing I will note guys, when I plug my headphones in that I hear a buzzing sound, I get the headphone icon in the NB. When I plug in the Apple headphones that I cannot hear the buzzing sound at all I get the headset icon in the NB.
I have read this is a Kit Kat 4.4 issue but I did not have it at all with a Galaxy S5. I am hoping it will be fixed soon but I am thinking about grabbing some different headphones anyway.
I have the buzzing just listening through the earpiece on the phone itself, no headphones required. I have the T-Mobile D851 model. So one would theorize that this is also using power since it's powering the earpiece to make noise. Some kind of electrical interference in the phone itself would be my guess.
Hi. Just got my UK spec G3 in the last few hours and I've just come across what I believe is the same problem. There is a distinct buzzing/crackling/static sounds when I have headphones connected via the 3.5mm jack. The sound is only present when I have certain media playing (using Spotify at the moment). I only notice this when connected using the jack and not when using my Bluetooth receiver (HTC BH S600). I did hear this while using two pairs of earphones while they were directly plugged into the device, the LG QuadBeat 2s from my G3 and the in box headphones from my old HTC One M7.
This has to be a software problem. I was just testing again and the buzzing becomes stronger in any app I use just when I touch the screen and scroll. I hope this is an easy fix in a custom rom. Also as I reported earlier, I do not have the buzzing during playback. I know this because I have tested some very quiet tracks and also checked on some very long gaps between songs. If it is humming it is much quieter. Only when I exit out of the Music app it is immediately quiet then it clicks in at about 2-3 seconds. I have also had a few quirks today where my headphones come up with the Aux Icon then after pausing the Music app a few times they switch to the Headset icon.
Not really sure what is going on but there has to be a software fix.
I will say the Music app sounds unbelievable with Viper4Android installed. It definitely has more oomph than with Play Music. Comparing the same tracks in both apps back and forth, the Music app is cleaner. Not sure what LG has done in that app but I like it.
I only get a buzz during charging. Disconnect the charger and it goes away. Most devices I've owned have the same issue recently. S4, S5, note 3, moto maxx, moto X, nexus 5 have all done it to me but only while charging
I have a really nasty popping crackling sound in between tracks when using aux in my car, but headphones no issues... Never had that problem at all on my nexus 5 so it can't be my head unit in my car
I wanted to post an update to this problem. I originally reported I had this issue with my Bose QC15 headphones. I do not have this issue with my Apple In Ear headphones. Today I was diagnosing things again and had been listening the the Apples. The Apples always correctly have the headphone icon show up in the Notification bar. When I plug in the Bose, I always get the Aux icon. This got me to thinking about if the cable was different. I pulled the cable out of the Bose and on the end that inserts into the headphones themselves there is a Hi Low switch. Mine was on high. When I switched it to Low, the G3 started to recognize them as headphones and not show the Aux icon. The hissing and buzzing immediately went away and its dead quiet. This switch is an input level switch and undoubtedly having it on Hi causes the G3 to not recognize the Bose properly.
There is a thread about the Aux input problem and I think they have it diagnosed. Its going to take some software manipulations. I listen to my G3 in my car through Bluetooth so I do not experience any issues on that end like the folks in that thread. As for headphones, I am not having the issue with my 2 sets.
Just a little update...
Updated to V10E, issue seems to be fixed...
No more buzzing noise in my left channel...

I have this problem when I plug into the car aux port (noise in between tracks). Just a quick question, which icon should appear in the NB if I plug in an audio cable from the Aux socket?

I picked up a D855 V10d (Telstra branded Australia) two days ago and noticed this yesterday myself.
I have Shure SE425 canals and they make the static noise when idle, very noticeable on these headphones. When music or audio is playing the static goes away. This is of course only when the charger is plugged in.
I tested it with the LG headphones that came with the phone and the noise is still there but softer, grabbed my Samsung headphones that came with my S4 and couldn't hear anything. I believe it's due to the resistance of the headphones.
Another test was to turn off the phone and charge it with the headphones plugged in, no static noise if I did this.
Going to exchange the phone today as it's unacceptable, I primarily use it at work to listen to music and often charge it at the same time.
Hey guys i noticed something that I would like to point out and ask you about.
When using the G3 on battery i get no hissing noise whatsoever. But the moment i plug it in the charger supplied i start to vividly hear hissing noises. I noticed that a hissing sound also comes from the charger and i assumed that its normal because of the 1.8 amps flowing through the thing. Is it normal or do i need to hit up tmobile for a replacement charger?

I can tell you I've NEVER gotten any hissing sounds when charging any of my phones, or my wife's phones, whatsoever, over the years. Even charging them from a near empty status AND using them at the same time.
One time last year, I got a hissing/crackling sound when charging my Note 3 and it turned out our kitten had chewed a portion of the cable, right through the sheathing and exposed some of the wires. The cable was shorting out a bit and creating that hissing/crackling sound.
I would try and see if you can replicate the hissing sound when using another charger and/or cable, to narrow down whether it's the charger, cable or phone.
Hissing from the charger block could indicate a defect in the stepdown transformer or a short in the charging cable. Hissing from the phone could indicate a charging port problem. Hissing from the battery could indicate a defective battery.
Of course, this is coming off your description of a hissing sound, which might be similar to a crackling sound, in which the above still holds true.

Are you sure your g3 does not have the hissing sound while charging? At all?
Sent from LG Gangster 3
All mobile chargers will make a noise. That sounds comes from the electrical components, as they chance AC electricity to DC at lower voltage.
I dug out an old block charger and that gives off a hum, not a hiss, when I use it and also when it's just plain plugged in and not being used to charge or pass current. The hum do is very faint. I don't get any hiss or hums on my other chargers, whether charging or not.
And yes, all chargers are stepping down voltage, but cellphone chargers on a whole should not be hissing. The current is not much on a whole compared to other appliances that hum (ACs, fridges, etc) that are pulling more amps and current through that transformer. You might get an audible hum or noise when your phone is pulling the full current with a deep charge and even more so while deep charging and using it at the same time.
You said you're hearing hissing, which is not the same as humming. If your battery or phone is emitting a hissing charge, then something is up. As I mentioned in my earlier post, hissing from your phone or battery might signify a defective battery and bad charging, the cells might be overheating or so.
I'm not sure on your setup or so, but one cause of loud humming on transformers is "dirty voltage", or when you have noise on your electric lines. All lines have noise, but depending on your electric supplier, they might have more noise on the line and that translates into the transformer.
You mentioned hissing and not humming again, so I'm assuming it's actual hissing you're hearing. If it was humming, then I would say that that is normal under use and so forth. But hissing is something different, especially if it's coming from your phone!
I notice that when i charge my phone and i out on my headphone there is a wierd noise. Is there a fix for this?

Does the Dash Charger make noice also, is it Normal? Thx!
Just checked but No Sound at all.
Mine does - a very slight buzzing whirling noise...have to have ear less than a foot away to hear it. Not sure if it's normal, but my Op2 adapter made pretty much the same noise.
Normally i would see cheap condensators placed.

Yes i have some situation. Power supply does a noise. Bit it'is very rarely
Sent from my OnePlus3 using XDA Labs
In my personal experience I have noticed an extremely high pitched noise from pretty much every mobile phone charging brick I have ever used. Nothing to worry about.
Mine has always been 100% silent, but if you're getting some kind of noise out of it, try plugging it into the power strip, or plug it in at a different location and see if it stops. It might be that the power coming into your house is "dirty". I used to build pro audio studios, and we always had to use power conditioners due to the power coming into the location giving producing substantial noise in the lines, both analog and digital.. A lot of it has to do with slightly out of phase AC current, and when it's switching to DC in the charger transformer it can make noise at the front end of said transformer. Also, the dash charger pulls a significant amount of current to be transferred so I can imagine some noise would be expected with unconditioned power going into it.
If it's annoyingly audible I would plug it in elsewhere and if it still makes the same noise contact OnePlus and get another one.
So Many people facing same sound issue inside the charger,its normal
Mine is silent and if the sound being emitted by your charger is like a buzzing one is extremely low then it can be considered as normal but if its even audible during normal room sounds then you should get it checked.
If you unplug your charging cable from the phone before unpluging your charging brick from the wall outlet, then some "charge" may remain in the charging brick. Just remove the charging brick from the wall outlet first, wait about 3 seconds for the remaining "charge" to transfer from the charging brick to the phone, and then unplug your cable from the phone. By doing these, there is no remaining "charge" in your charging brick and it won't make that buzzing noise. That buzzing noise occurs on all of my other charging bricks as well (for samsung tablet, lenovo smartphone, oneplus 2). Of course, if the charging brick makes that noise, just plug your cable in the phone (without plugging your charging brick in the wall outlet) - this will transfer the remaining charge from it to the phone and the charging brick will stop making that noise.
