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.

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.

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

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.

Yea i have this as well it hasn't affected charging or flashing tho... When I plug in my friends blackberry charger it clicks in nicely though.

Alright I know this sounds weird and you probably think I'm crazy but here we go. My wall adapter for my charger makes squeaking noises. Imagine a cricket got trapped inside it somehow. That's what it sounds like. Its kind of quiet but definitely noticeable. If I unplug my phone from the adapter or unplug the adapter from the wall, it instantly stops. I'm using the stock Motorola charger and micro USB cable. Should I be worried?

If it is just a high pitched whine, its probably ok. But if it is sporatic chirping there may be as short in the transformer and that is not safe.

It might be that one of the bearings on the hampster's wheel is going bad. I'd let it go for now. The only risk is that the hampsters get massive quads from the extra force needed to turn it.
If your into fixing those kinds of things yourself, like I am, and don't mind cracking it open, check the capacitors inside your charger. Electrolytic capacitors are prone to failure. My power adapter for my XM Radio did the same thing, when I opened it up the capacitors had burst and were leaking. It's a cheap fix.
Or you could just buy a new charger, lol.
Voidwarranty is definetly correct my knowledge of pcs says thats a capacitor you would have to be willing to solder but it would be easy its a common problem with cheap graphics cards or motherboards

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..

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.
Anyone notice anything similar on their devices?

Well its a known issue. My galaxy tab plus also had the same thing and my notes charger as well. But it will self resolve once u put it in another plug. Its transient for me, sometimes

It is SATAN.
When I had the note 2 it made a weird noise when charging. I had 2 different chargers.
That high pitched noise is not normal.
These chargers use a switched-mode power supply that usually runs well above the audible frequency range typically several 100KHz. Some designs cope with a light load such as close to end of charge by cycle skipping and this can bring the frequency down into the audible range. This is not a problem per se but may be audible if the transformer is not totally encapsulated. It's like the hum you may have heard on a 50/60Hz transformer but at much higher frequency.
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.
