The Samsung Charger that came with my Nexus...

Emits a high pitched ringing when plugged in that made my girlfriend think she had ringing in her ears. It does this even without any draw. It also smells a little bit like burning electronics so I assume that means its toast and/or a hazard. Think I can get a free replacement from Samsung?

Probably not.. they only cost like five bucks though

Take it to Verizon or call them. They'll swap it out if it has a problem.

Mine makes the same sound, but only when it's plugged into the wall and not to the phone.. When I plug the phone the noise stops.. I guess it's normal... I can only hear it when it's really quiet in the night..

Mine does the same thing. I spent 30 minutes trying to figure out where it was coming from.

You're assuming he's got a VZW version

My first vzw nexus charger had the issue and I got a replacement from support. It was lent a Samsung charger, just a generic charger but it has like a ten foot cord so I didn't mind! Anyways then had to get my nexus replaced (random reboots and a column of dead pixels bothering me) and got a new Nexus and inherently a new charger that ALSO has the ringing issue. Luckily I still have the replacement charger from before so I'm using that.
Pretty disappointing I got stuck with two annoying samsung chargers in a row though and I'm just leaving the USB cable connected to my computer.

Yup same thing here. I only hear it at night when its quiet. When phones plugged in it doesn't make the noise.

Wow, really? That's nuts...

Yep! I figure I can't complain about that but kind of miss the quality of my of Droid... that thing was a tank and so far my experience with samsung quality is not the best. Luckily I love ICS!

Is it high pitch or a low buzz?
My dell laptop's charger had a low buzz when it was quiet, never heard of anything like that from a tiny adapter like the one for phones though.

High pitch
Sent from my Galaxy Nexus using Tapatalk

Mine is high pitched when the phone is not connected.
When the phone is connected it still makes a sound but it is a more deep hum but I must put my ear right near the adapter to hear that.

Common issue for these chargers. I have iPhone and blackberry chargers that make the same noise.
Sent from my Galaxy Nexus

I think it may be common for chargers in general as my electric toothbrush charger does this too ever so slightly. .
Sent from my Galaxy Nexus using Tapatalk

It's called inductor/capacitor hum and it's normal and varies a little bit from device to device. Essentially it's just a very fast vibration.

Just for the record, I also have this high pitch squeeling from Samsung charger, only noticeable when not charging. My old SE charger 5V 700mA does the same and my 6yo HTC charger 5V 1A is quiet I think this sound has gotten worse since the chargers has become more idle efficient (not wasting power when not in use)

Nexus phone charger noise

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.
Sent from my Galaxy Nexus using XDA App

Mine does if the phone isn't plugged in. I plug my phone in and it stops.
Sent from my Galaxy Nexus using XDA App

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.

Do you charge your Gnex with Nexus 7 charger?

I love how my Nexus 7 is able to charge my phone very quickly. Do you use the N7 charger on your Gnex without problems?

your other thread you started asks about your phone smelling like burnt plastic. maybe you should use the charger it came with and see if it still does that

I don't use the N7 charger on my phone regularly. I used it last time I went on a trip because the original was at the house.
Sent from my Galaxy Nexus using xda premium

should be okay. your n7 charger provides more current than the standard gnex charger. the phone's charging circuitry will only draw in as much current as it can take without damaging itself.

ever single electronic device i own i charge with the charge with the charger they came with

I have random chargers laying around everywhere. At work I charge with my old Nokia n86 charger. All good. :thumbup:

I been using my old HTC charger for my galaxy nexus on an off for the last 12 months with no problem, I never heard of anyone damaging their phone using other phone chargers that fit, if you lose your charger an buy a generic charger they work the same way without needing one made by Samsung, I know most phone manuals will tell you to only use charger supplied with phone but they always says that an rather you get a replacement through them.I also use to lend my gnex charger to other people at work who owned HTC phones all the time an they have no problem with it.

The entire idea is to have the micro usb system universally, all manufacturers / os. Only apple messes it up.

I use the charger it came with and also several other generic ones (car, work, second office) and all seem to charge fine with no signs of excessive heat. What about charging time? I just came from the HTC Thunderbolt and would leave it charging over night. I thought I read that is not recommended to do with the Nexus. Does anyone leave theirs charging over night?

I plug my galaxy nexus in every night before I go to bed to charge overnight since I got it last December that way its fully charged an ready to go when I go to work every morning, I have done that with every phone I have owned , I don't see how that's a problem.

GNex ~ N7 charger :good:
N7 ~ GNex charger

MicroUSB plugs are universal so all should work fine. Only time it'd be bad is if the wiring in the outlet you plugged into is done improperly.

It should be fine, as someone else stated earlier, the N7 charger is capable of supplying more current, but in simple terms it's a "suck" rather than a "blow"
The devices will all have regulator circuitry in to prevent damage.
The other way around is tedious (charging the N7 from a GNex charger...zzz)

Nexus 7 charger killed my gal nex

Kinda had a feeling to not use it as it's a higher voltage but it would charge my phone so much faster it felt like. Well now the phone will just reboot no matter what rom or stock rom I use. If it does get to boot up the screen starts flickering and you can tell something is wrong. It stays on fine in recovery or bootloader but nothing else. I can flash anything the problem is when it needs to boot up. It's very weird but sprint is sending another after they tried to tell me it's because it's rooted.

Wow good to know, almost used it last night to charge my gnex

Strange. I've used sooo many different chargers everywhere I go and never had a problem. If its micro USB, I use it.

I used the n7 charger one time and I swore I smelled burning plastic or something....never again will I use it on my gnex.
Sent from my Galaxy Nexus using Tapatalk 2

Errrr . . . I actually suspect you've just stuffed yourself up some other stupid way. (or the charger you used isn't actually a Nex7 charger)
The Nex7 charger is not higher voltage. It's 5v, just like the GNex expects. It's a 2.1amp charger, compared to a 1amp one for the GNex, but that's irrelevant, as chargers don't "push" current to a phone - they'll only give it what it asks for, so using a 2amp charger with a device that expects a charger of 5v, 1amp, is not a problem - it'll just give it the 1 amp.

Yes he's ^^^ exactly correct. The voltage is the only concern here.. and it's 5v like every other USB charger should be.

I have charged my gnex into a 24 volt outlet an still didn't get problems lol

im guessing the issue lays someplace else too, not with the charger. i use my nexus 7 charger on my galaxy nexus every day, without burning smells or any other issues. id say ive used it at least 10 weeks in a row if not more.

hmmmm I use my Nexus 7's charger with my GNex all the time... and no issues

The only issue I've had with the N7 charger is the USB cord end is too fat and messed up my old charging port otherwise it was fine for weeks

Did that same thing happens, maybe it is not the charger but pretty much it's something hardware no matter what software I load it reboots at random times and screen flickers. I was just using the phone one day and it rebooted and never stopped. Tried everything known to man to get this phone to work.
I also was using the nexus 7 charger for weeks and the only thing different was the usb cable is a blackberry but that should not matter.

I use my iPhone 5 charger

I use a kindle charger (and its long usb cable) to charge my gnex all the time.. and that thing is meant for all eink kindle models including the dx. No issues at all.
Have also used iPad charger, old gravity touch charger, iphone charger, 5v is 5v.. so don't really matter what charger you use .

I can confirm that I have used my n7 charger with an aftermarket cable/n7 cable/gnex cable about 20+ times n i never smelled any burning plastic/metal/rubber/carbon fiber. My gnex still performing exactly as b4, except the sucky 4.2 update, that is. That blows, big big time. I mean, i seriously had the desire to slam the damn thing in the wall so many times. But I digress.
Conclusion-Either I have a special super gnex, or n7 charger doesnt affect the gnex. charging speed=slighly increased though. slightly. like 15mins lesser.

I've used a nexus 7 charger with my gnex 50 times+, no issues.

I've had 3 Android devices and 3 chargers. I don't even know which is for which, but I've never had any problems with charging any device with any of the chargers.

Definitely no issues. I've been using Nexus 7 and Blackberry Playbook 2 ampere chargers without problem

[Q]Wall Chargers

Does anyone else have a problem with their wall chargers dying on them? I don't know if its the wall outlet itself or what killing these things. I've had 2 die on me since I've owned this phone, but never had problems when with other phones with microusb chargers. I probably just need to change out the outlet, was just wondering if this is a common problem for others?

Never had or heard of this issue (until now) I would guess it's the outlet. But...hmm...is it the cable or the AC to USB part that's actually dying?

Are you using a aftermarket charger, is it plugged directly into the wall or is it connected to an extension cord? Sounds like it could be the wall outlet though.
Sent from my stock rooted Galaxy S3

I had the original one die on me as well ... but, I was plugging it into an inverter (modified sine wave) so not apples to apples.
I just scrapped it and started using an old Blackberry charger and have had no issues for months.
I just chalked it up to a defective charger and went on about my way.
No help I guess, other than I did have the supplied one die while the BB one chugs right along with the same type of connection.

Well, the stock one died on me. Then i used my Motorola one and that died on me.. and my car charger I've had for years died on me today as well... I'm hoping it's just my wall outlet, but its weird that my car charger died, too.

That sounds really strange . What makes it even weirder is that you've gone through three of them. I would defiantly check the wall outlet / s . As for the Car Charger if it has some years on it. The fact that it went south on you might just be a coincidence.

My father in law had 2 charging cords go bad on him already ....maybe try a after market one instead of a OEM charger

Now there's an interesting point. How many of you with Charger issues are plugging straight into the Wall, vs plugging into a Power / Surge Strip ? I'm not saying it matters. It would just be interesting to find out. I also have my Charger plugged into a Power Strip with built in Surge Protector.

Mines is straight into the wall, using it for my shift now but yeah. My sisters is straight into the outlet as well
Neither of us have had issues

Mine was in an outlet... many many different ones too. Sprint tested it and told me it was bad. Bow I am using the LG rumor charged I got in 2009 and it still works just fine. I had to move both around a lot so i don't know why Samsung one broke, other than it was USB?
