Why does the stock charger buzz so much? - Nexus 4 Q&A, Help & Troubleshooting

When I leave the charger that came with the N4 plugged in, it makes a noticeable buzzing noise. Is this common?

I think some of the charges are just defective. Sometimes my charger makes a noise even after it's unplugged for a couple minutes. I tend to use one of my other chargers/usb cables for my phone because I never have luck with my pc seeing my Nexus when I use the factory usb. I use my Samsung camera usb or my old vibrant charger with no problems.

Mine stopped working after awhile I started noticing the buzzes.

That happens because there is still some charge available in the capacitors. When the charge is "gone" the buzzing stops.

I've had two Nexus 4s, as the first was defective, and both chargers buzzed when the phone was not plugged in.

Screen fails when charging!

why when you plug the phone up to charge the touchscreen goes nuts can this be fixed with a software update?
edit:wrong section please move
you are using a different charger from the one recieved from the phone or you are using some old and faulty usb port from a computer.. These problems are reported in the Apps and themes section actually the wrong place 2

Im using a cord I was provided with
Sounds like either your cord or your phone has a problem. I'd exchange them while you can.
ok it does not do this when I plug it into my room or my other PC so why does this happen when I plug it in my living room or in my laptop! Ive about had it. I hope this is fixed with a software update

There's no problem with your phone, software or hardware. The problem you are experiencing is from the usb port not providing correct voltage that the phone need. Use the cord with the provided wall charger will not give you this problem.
Same thing happened to all 4 of my touch screen phones when used with some third party chargers or low voltage usb ports.

That's pretty strange. It sounds like the circuit in your living room has more noise in the power, but usually a DC charger should reduce that enough.

DC charger?
I plugged in an eBay cheapo charger and screen's touch goes all wonky on me too.
no software can fix what is clearly a voltage issue coming from either your charger or the source that your charger is plugged into. Had the same issue last night on a walmart charger but when I use the provided usb cable in a decent usb port or the wall charger provided by samsung, the problem goes away. I would steer clear of using the problematic charger/usb cable/wall outlet to prevent possible long term damage to your device.

I noticed it happens when I have two plugs in my wall. So this is my outlet? How am I suppose to charge my device then? I REALLY want this device and do not wan't to return it because of the power issue. This didn't happen to my G1, im guessing because it used up less power?
Same thing happened to me so i took it back to BB and exchanged it. Its the phone. Go ahead and exchange it.

I have this problem came with my current touch screen and my previous blackberry storm.. I used a cheap charger and I have this problem, or even if I use my wife's Nokia also like this.. what I do is pull off the battery and reinsert and your problem will gone.. alternatively, use back the original charger.. or your case, avoid using the socket which gives u the problem like your living room..

are you using your computer to charge the phone or is it plugged into the wall. i know a few people had the same problem when a computer was being used to charge the phone.

if you're using your computer, it'll keep happening. just to be on the safe side - exchange the device.

This does not happen when I plug it into my pc can you explain that? Also I'm not going through the hassle of returning the phone again just to have the same problem occur because it is not my phone.

Loud buzzing from wall charger

Just wondering if anyone else noticed this. I unplugged the wall charger today and noticed it was buzzing. It continued to buzz for about 30 seconds after I unplugged it.
Maybe I have a bad unit? Or is it normal. It takes about 3 hours to charge to full and for it being a 1.2 amp output charger that seems kinda slow. I figured it has something to do with the lithium polymer battery but maybe it's the charger?
Going to bed now but I'll try to get a video recording of the buzzing noise in the morning.

Would it be more like a "whining" sound from an internal capacitor discharging? I recall hearing that sound as well, when I switched off the charger and unplugged my phone. I think my previous HTC charger had that sound as well.
My OEM gnex charger does this but it's going through a UK adapter also
Sent from my Galaxy Nexus using xda premium
I'm pretty sure this is actually a fairly common trait of mobile device chargers, and it has something to do with the rectifier(?) used to change the current from AC to DC to charge the phone. It shouldn't buzz at all when you have the phone plugged into the charger.
I simply remove my charger from the wall when the phone is not plugged in. I save a (minuscule) amount of energy this way, too.
FWIW my charger buzzes like crazy too (UK).
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 just realized my charger was having this issue too. It's too quiet to hear in most instances but if I get real close it easy to hear. It's very high pitch.
so is this normal?

It's normal. My Gnex charger does this as well. There was a thread in the Gnex forum that discussed this and I believe it was said that it was the capacitors making the sounds which is why when you unplug it the sound goes for another second or two before fading away.

I thought I was hearing things until I put my ear up to the charger. It's definitely audible from a distance...but mine isn't high pitched. The buzz I'm hearing is almost a tiny motor as odd as that sounds.

Same here. I can't sleep with it next to my bed it's so loud. I'm just using a charger from my old phone. I've used like 10 different mobile chargers and the n4 one in the only one that I've ever had that has this issue. US version.

Faulty chargers causing battery problems?

I'm wondering what the easiest way would be to test the charging voltage going to your phone from the charger. My experience has been that the first time I charged my phone it seemed to charge up just fine pretty quickly, but then drained pretty quickly also. The second time I plugged it in for about an hour or so and it had only charged up 10 or so percent and the phone was pretty hot. I was thinking maybe it was the outlet or something, but when I plugged it in to another one the charger started making this buzzing noise, and continued to buzz for about 6 or 7 seconds after being unplugged. This concerned me, so I switched chargers to a different one and it charged up my phone no problem and I have pretty good battery life.
I'm not sure how widespread this is, but I've had a few other people say they have the same issue as me with the buzzing and everything. One guy's phone phone got bricked completely before I mentioned to him that my charger was buzzing and he found his was also buzzing. This is just something to be aware of if you're experiencing heat issues or charging issues. Is there maybe an app that displays charging voltage?

Hmm... My charger also buzzes when unplugged and plugged in. I noticed it before but didn't pay attention to it. I guess I'll use a different charger. I hope this hasn't killed my battery in any way.

My GNex came with a buzzy charger, I used it for two days before swapping for a new one and had no problems with it.
Is the LG charger broke? Maybe. Is the LG battery super sensitive? Possibly.
I use about 3 different charging blocks and cables on with my HTC onex and My Nexus 4, It doesn't matter at all which I use with either phone, the n4 still has crazy heat.
One thing either way, Never use a noisy charging block IMO.
My charger buzzes as well, and my battery life seems to be on the poorer side. I kind of doubt the are related, but perhaps they are. Would they send a new charger with a replacement unit?

My charger also buzzes occasionally and will continue to do so for ~10 seconds after being unplugged. Should I be concerned?

I'm in the same boat. What's the deal with the charger?
My charger also buzzes. I don't think it's defective though... Seems like everyone's does, plus it seems to be working fine. I just assumed it was some kind of capacitor discharging inside or something.
Just played around with it and it seems like the block buzzes when plugged in until you plug the phone in and it stops. Mine proceeds to buzz for a few seconds after unplugging as well, as others have mentioned.

[Q] Charging problems

So I went to plug in my phone using the stock charger and it would not charge. The charger would however charge other devices including my N7. I tried several different chargers and none would charge it. My N7 charger was here at work so I could not try that until now. Plug it in and instantly charging. Why would the N4 charger quit working on the phone but still charge other things.
Im so confused!
It probably has something to do with the terminals inside the connector. They must not be making a solid connection
the wall plug in part of the stock charger is junk. mine makes a loud ticking noise and gets really hot. i don't trust it, i use the stock charging wire with an old HTC plug in and its been problem free

Does your charging change from AC to USB?

My nexus so far seems great but i have this issue and idk if its a defect or idk? When i go to charge my phone with the stock AC adapter and even a HTC adapter it starts charging on AC then sometimes switches to USB and charges slower. And I have to like plug it in and out a few times for it to finally catch as AC its super annoying and my GNex never had that issue. And when i want to use the phone on AC the Charge Drops significantly sometimes discharging and im not even doing anything intensive. Does anyone have this issue? Is it a problem with the USB cable maybe? Or do you think this is a defect? Because its about to be 14 days and i dont have much left to get an RMA cause its what im considering and if I need it i dont have 380 dollars in my bank account either if i do need it so idk how that would work. Any help would be appreciated Thanks!
It lowers the incoming current, by dropping to usb charge, to help keep the battery cooler. They seem to be really trying to keep the battery temp down on this thing.
Ordered my Nexus 4 on the 13th. Still waiting.
Really? Do you know the temps? Or does anyone? Cause sometimes it changes to USB after plugging it in for like 5 mins and i wouldnt think it gets that hot that quick. And when i finally get the AC to seem to stick the temps go up to 30-35 degrees celcius as normal and im getting around 850mah and it doesn't drop to usb charging it just drops current sometimes mainly when im using it obviously. So idk if it really is what you say or maybe someone could elaborate more?
I just want to get to the bottom of this issue so to know if i need to get an RMA :/
I forgot to mention that it also seems to randomly switch between AC/USB/UNPLUGGED really fast sometimes and i have to unplug and replug to get a charge I have no idea why.. I really want to know if its a software issue or hardware. Thats my main concern.
Woww this makes sense Ive been trying to figure out why this freaking thing was taking so long to charge. this reminds me of the galaxy s and how long that thing took. hopefully this is a software bug and they can get this thing worked out

Yea idk if its a hardware or software bug im hoping software but i may just do an RMA incase if i can ill call google tommorow. And if you want to check how your phone is charging you can download Battery Monitor Widget it shows the mah and all that.
I have that same problem with the charger that came in the box.once it goes to USB it take forever to charge but when I use the charger from my gnex it stays on ac and charges really fast not once does it goes to USB.so I tried the N4 charger on my HTC thunderbolt and gnex and both would go into USB mode and charge really slow.

For what it's worth, my Nexus 4 *NEVER* charges in an AC mode using the OEM charging plug, regardless of which power point / cable I use with it. And to charge from 'critical' to 100% took about 7 hours last night. Wtf.
It's been RMA'd as I don't believe this to be correct behaviour. Perhaps also related, the USB computer connection has stopped working. It'll charge via USB but won't connect to any computer.

Hmm so did you use the Gnex charger like the USB cable and AC adapter? Cause ive just used the ac adapters with the N4 Lg USB cable. It makes me think that the USB cable is **** to. I need to find another USB to test this out.

Yep, tried a whole bunch of different power sockets, usb charger plugs and cables. Still screwed. The more I read, the more its obvious that the devices behaviour isn't correct.
You should send it back because mine charges fine. It takes 2-3 hours to charge mine to full from empty. I'm using the charger and USB cable that came with the phone.
I'm actually facing the same thing, I slept for 3 hours and woke up to my phone being only 60% charged. I tried plugging it in and out a couple of times, and now its back to AC and not switching to USB anymore.
In using Franco kernel and even enabling USB fast charge doesn't keep it from showing USB.

Yea mine is missing it to I wonder if that is why? And i just got my RAVpower external battery and that usb has all the pins and i tried to charge my phone with the lg brick and the ravpower usb and it seems to charge fine goes to ac every time. So im really wondering if its the LG USB that i got and it being faulty or not. I need to get another USB to test this out. Cause i dont want to swap out an entire phone for just a usb..
I've noticed mine charges as USB when using the stock LG charger. I had put it down to the 3 metre USB cable it was attached to, but I guess it's just a pants charger.
I just started having the same problem since Sunday. Had the phone for 2wks now. I had the same problem with my gs2. I really don't like these adaptor charger now a days. I go for the straight wall charger. Seems to work best. I think it's better because it doesn't convert to a usb cord as well, I don't know but I went ahead and ordered this one. http://pages.ebay.com/link/?nav=item.view&id=150959459340 should be here Friday. it says original OEM charger for E960 nexus 4. We'll see.. I suggest direct wall charger instead of those USB adaptor that come with phones now.
I just looked at my USB charger from lg, it has 4 gold pins. Seems like they're all there, how many are there suppose to be??

That actually sounds like a good idea and should hopefully work! I need to order one. Still debating on Getting an RMA cause i dont want **** phone or worse phone..
Correction And it should have like 2 gold outer pins and 3 gold inner pins and mine and I guess a few other people have the outer pins but only 2 inner pins im missing the left most inner pin.
