My charger definitely makes noise... It's usually not a problem and caused by some internal components

My galaxy nexus charger had this same type of issue. Although it would only emit a noise when the phone wasn't hooked up to it. Kinda reminded me of coil whine on certain video cards.

My charger makes the noise too, usually about 1h of use.. Also the charger from my previous lg phone (Optimus 2x) used to make the same noise too. My wife's s2 charger does not make any sound at all..

So I suppose its the way it is and its not a sign of faulty charger is it?

did anyone request a replacement charger from Google or is everyone just accepting it for what it is?
p.s. i found 3 threads for this issue...

I have this issue to. It's annoying when I wake up in the night and can hear it.

Mine is super annoying. I wouldn't be able to sleep with it charging beside me.

same here, noisy when the Nexus 4 isn't plugged.. when I plug it - the noise stops..
I care less about the noise, but can it be dangerous for the phone?

My Chager also make a noice
My Nexus 4 Charger also make noise
actually it buzz like a bee
But just when the cellphone isn't conect to it while conected to the electicity
when I plug my cellphone to it the noice stops!

May be the Nexus 4 charger is mice powered.

my Nexus4's USB charger is noisy

I bought my nexus in hongkong several weeks ago, and then I went back home in China mainland. Then I tried to charge my phone in the night. I found the usb charger was noisy, though the charger could charge my phone without any problems and the sound is not very loud , but it was loud enough that even I could not get asleep because of the noise. Does anyone have the same problem?

Nobody has ever noticed this before. If you were to have searched, there's no way you'd find people experiencing the same thing.

I hear buzzing but I have to be really close to it.

there is a possibility of getting a faulty charger.. just get rid of it and use a compatible charger.
also check the ratings compatibility

Lots Of Headphone Noise

When I'm using my N7 to play music I get a lot of white noise in the background. It's barely noticeable in loud songs but when listening to a quite song or nothing with the headphones plugged in it is extremely noticeable. Does anyone else have this problem and has anyone been able to fix it?

What headphone you use? My nexus is also make noise with my sensitive iem (cx300 II).

I notice it with both my Klipsch Image S-4's and my Bose Quietcomfort 3's. The Bose are noticeably worse, probably because you cant hear anything else.

Unplug the charger? I have the same problem but it's only there when I have my N7 plugged in.

I'm with clintvl. I have the same issue only while its plugged in.

Mine is with or without it plugged in. That makes sense though, with a car charger the noise gets really bad.

AW: Lots Of Headphone Noise
I've got the same problem. No matter what headphones i use or whether it is plugged in or not, the background noise is there and very annoying..

High pitch mains charger squeal cure!!!

Does your mains charger squeal with a high pitch noise that makes you want to bang your head against a wall?
Well suffer no more! Here's the simple solution - make a tiny loop with the charger cable at the phone end and rest your phone on it to keep it in place. Voila! The squeal that makes you want to kill is gone!
Let me know me if this works for you. Peace!

Use blackberry cable.
Faster charging.

It work.

How do you go about doing this? Sorry but not clear to me. I have this noise problem as well when charging.

OP: What country are you from?
ie Voltage / Frequency
Not a problem with me @ 240v 50 Hz....
I'm an electrician, and this piques my interest.

I'm in UK 220 volt, 50 Hertz. I have this high pitch sound from charger that is not constant. It goes higher at occasions during charging. I didn't try another USB cable though.

I have tried other cables, it didn't help. Must admit I am curious about fixing the problem though, it drives me insane.
I am a little concerned that its a fault in the PSU though as the power light on the phone changes brightness and it seems to coincide with the noise changing on the PSU.

OK, make small loops of the cable near the phone and rest the phone on the loop just to keep it in place. Try making one or two loops and listen for the change of frequency. Also flipping the mains power switch can help change the frequency.

Omfg Thanks! It works. Been irritated for so long since the days of my trusted old nokia 6610..

Well i found the problem is not with the cable but the plug itself must be a fault with the design aspect of the housing of the seperate charging plug not being allinged with uk plug sockets correctlym The pitch to it is very similar to a squeal of electrical connection that doesnt have a consistent voltage running through it due to a loose connection being produced from a loose solidified object such as 1 of the the the bottom connectors (try any other plug like a toaster coffee machine etc they will give the same noise when not connected properly). Cant see it being the plastic adjustable top plug as it bares no real objective to the charge other than an earth connection.
I changed my plug from the samsung provided charger to another usb plug-in charger adaptor whilst still using the offcial usb cable that came with my note 2 and have noticed the noise has disappeared and it charges a bit quicker as a bonus. I cant say iv tested the 2 adaptors parallel to each other YET but when i can be bothered maybe il look into it. (For the picky readers in xda i am in my final year of electronics engineering so i kinda have an idea what im talking about just cos my avatar is dressed as a duck doesnt mean im dull as f##k)

Nice try but your wrong. Only high current electrical appliances is connected to earth these days.
Why is it when I use the same power socket for my tv and my charger and only charger gives out the high pitch noise?
Say your theory is correct. Why is looping the cable solving the problem?
I graduated in electronics and electrical engineering from leeds with years of working experience so I know what I'm talking about too.

I don't know.. Voodoo? It works for me, and others it seems.

Or maybe looping affects impedance changing the frequency just enough? I don't know I'm no scientist!

I just got used to the sound. Initially I was having trouble sleeping but now it's all fine. With the looping.

For me it sounds like that only when phone us fully charged.

Same here, silent till it hits 99% or 100%, then this quiet squeaky noise starts

I've also discovered the charger continues to squeal when you unplug it. I think it'd sending subliminal mind control messages regarding the purchase of your next phablet.

I replaced the cable with a blackberry charger cable. Not only is it fixed, but I have a better charge rate which makes me think the original cable was faulty.

Charger Makes Vibrating Sound

This is an extremely strange phenomenon. When I plug my OEM LG charger into the wall, it makes a faint vibrating sound, which persists for a few seconds even when I unplug it. However, it goes away when I plug the phone into the charger. Is this a widespread issue? It seems to charge very well anyway.

It's normal, It's called coil whine. All of the chargers I've had made the noise. http://en.wikipedia.org/wiki/Coil_noise

Interesting, thanks. This is my first charger to do that. Must be just a coil that isn't very well secured.
