I noticed that my Nexus charger makes noise when it's in the wall with my phone unplugged.
The sqeaky sound goes away when i plug in my phone.
Is anybody else experiencing this?
I'm going back to the store tomorrow for a replacement.

well, every charger i had was silent or at least never make a big noise like the cheap samsung one..a little noise can be normal for a charger, but hey the samsung one does a very high frequency noise..
never happened with other charger, because usually it is plugged near my bed..the first night i plugged the samsung charger i noticed it soon..
anyway it seems to happen with about every samsung wall traver charger of every phone..btw i "solved" by just plug the charger when i have to charge the phone..
I have the exact same issue. I have a socket with an on/off switch on my night stand table that I switch on/off when I need to use the charger. It's mostly to get rid of the high pitched noise though. And yes it disappears when you plug your phone in.
Mine even makes a 'discharging' squeak noise when I pull it right out of the wall socket after letting it squeak for a while. It's probably the capacitors inside charging/discharging. No harm, but annoying.

I just used the usb adapter for the first time today and when I plug the usb cable into the phone the adapter makes this high-pitch frequency sound. It's similar to the mosquito ringtone that teens love so much. It stops when the phone is done charging. Does anybody else have this problem?
I noticed this yesterday, but it was only when the Incredible was fully charged.
I'm cycling the battery right now, so when I plug it in again...I'll get back to this thread.
I know it happened to some others but could not find the post. While im charging my nexus, there is a whistle sound that can be heard, this happens when im using a Samsung car charger, but with others, it was reported as wall charger too I think. Can this damage phone? It charges fine, and this doesn't happen, or I never noticed when charging via usb or at home

It's probably the cheap capacitors in the power supply. No worries.

Happens to me to, its the cheap usb/charger samsung supplied, I use a dedicated usb charger from a previous phone with no problems, hard to sleep with the hissing next to your ear.
My home charger was whining last night prior to me charging in the phone. That was the first time I've heard it before. Kinda freaked me out cuz I was getting ready for bed.

Does anyone else's charger make a high pitch noise when it is plugged in? Same noise if phone is charging and if not connected. Mine has done this since day one no matter where the charger is plugged into in my house. I haven't noticed it elsewhere but there is usually more ambient noise other places I go. I've never heard a charger make noise before and just wondering if this is a defect that is going to burn my house down.

Mine does if the phone isn't plugged in. I plug my phone in and it stops.

Same here. I meant to clarify and say that it does it when the phone is plugged in but only after the phone has reached full charge and stops charging.

my charger does the same... but I use my PC to charge my phone... only used the adapter twice...

Mind does (well, 'did') the exact same thing. I threw it out and bought the powergen version on amazon. no more crazy high pitched whines. Was driving me out of my mind until I discovered it.

The N7100 Charger hisses (only audible when you place your ear close to the charger) whenever connected to the wall outlet; removing the charger, the charger continues for another 2-3 seconds before actually silencing. Is this normal?

Yes, that's perfectly normal. That's the sound made by capacitors inside the charger. Unless it gets so loud you can hear it from 25 meters - there's no need to worry.
Thanks!

I don't think is normal. You need to send for RMA. No harm exchange for a new
charger.

No mine also does a bit like grinding something or like a juicer heard from far away

My charger makes a hissing sound too and it would suddenly stop hissing if you unplugged it. Tried the charger that came from the Galaxy Tab which is also the same as our rated voltage, current, power and it does not produce a hissing sound.
Its perfectly normal
My previous phone's charger used to hiss to. This sound occurs mostly when the battery is up to 100% or close. Don't know the science behind it though...
No it is irrespective to everything.

I have a rooted stock 4.4.2 Nexus 7, and I'm encountering a really weird problem where there's a persistent high-pitched whining noise that seems to come out of the speakers whenever it's plugged into a wall charger. I tried the stock charger + cable that came with my device as well as 2 other third-party chargers all with the same results. Meanwhile, charging it via USB connected to my computer doesn't produce that sound at all.
Does anyone know if there are any tweaks or settings that could be causing this? I looked in the FAQ, and I only see a giant thread about static while at low volumes, but this looks to be a completely separate problem since it's unrelated to volume settings & it happens when I have no sound playing at all. Googling this returns a bunch of results with people's chargers making noises, but not the Nexus 7 itself.
If anyone else has had this problem and can offer any insight, that'd be appreciated. It's not the biggest deal in the world, since I just have to make sure I'm not in the same room when it's charging so I don't get annoyed, but if I can fix it, that'd be great.

Maybe a ground loop. Can you ground your tablet and see if that helps. Just a theory at the moment.

Sorry for the dumb question, but to ground it, just have it touching metal?
Also, a new piece of information: I found that the noise only happens when the tablet is fully charged (100%) and still plugged in, so it happened last night while I left it in to charge after going out. I'll have to wait for it to fully charge again before I can test this theory today.

Not an extra ground, isolate the ground. Make sure the tablet and charging brick are grounded well. Is your outlet/house grounded well? Can you use an outlet with nothing else plugged into that line?
You say this only happens when fully charged and not until? I wonder if there is a problem with the battery perhaps over charging. Have you switch charging bricks? Switched cords? Does the charging brick get warm? How about the back of the tablet?
Edit: Are you using the official cord and charging brick? That can make a difference. If not what are the specks of the brick you are using?

Another new piece of information discovered today: The high-pitched whine only happens when the battery is 100% AND when the screen is on. When the screen is off, everything is fine.
So far I have tried:
1. Directly plugging into the outlet the stock Nexus 7 charging brick & cord.
2. Using the following bricks: Stock charger, Anker 40W 5-port USB charger, Amazon Kindle charger, Moto G stock charger. I've also tried all the cables that came with these devices as well as any other microUSB cables I've got lying around the house.
3. My device is not hot at all, and neither are the chargers.
Thanks a lot for your help so far! Looks like what I need to do is to turn the screen off to charge my device, and then unplug it when I want to turn the screen on & use it.
