[Q] Noise when charging

Hi, does anyone hear the very high pitched sound when charging your phone?

Nope, mine's on charge right now and silent. What charger are you using?

I am using the original LG wall charger. I found that some phones were having this problem too, and some had this problem just for a certain rom @[email protected]

Its not the rom its your charger.Even if you leave the charger plugged without charging the phone after some hours you ll hear it.. original charger from lg!
Dont know why though..

Charger Whistles?...

I just bought this phone from wind (called optimus 2x but is LG-p999) and when i plug in the my phone to the wall charger, it does this wierd whistling noise that is kinda annoying. When i charged it with the computer there isnt that noise so i know its the wall charger. Does this happen to anyone else and is there anyway to fix it?

lol no, somethingg has got to be wrong

The one thing i didnt want to hear I guess i should return it.
Edit: Also, is charging faster with the wall charger or is it the same thing with PC?

Wall charger is faster, 1000mah as opposed to 500mah.
Definitely faulty though. Any old USB charger will do to tide you over.

I don't have any usb chargers, just the phone's. Also do you guys think it could damage the phone in anyway?

I wouldn't have thought so, noisy transformers aren't exactly uncommon, but they are annoying.

i wouldnt worry mine does this with no ill issues. A few of my chargers over the years have also done it. Some people are just more suseptable to noise than others lol.

My charger is whistling as well. But I wouldn't be too worried about it...

mine whistles when its almost full. like 90%

It's a Characteristic of Switched Mode power supplies
All of my later Nokia chargers did it, And My HTC
It can be annoying but nothing to worry about

Mine makes a weird clicking noise.. When it's been charging for a while (the charger, not the phone), it even continues after I pull it out of the wall socket!

the lg charger is ****, get an iphone charger from ebay or dealextreme, at least thats what i did

mine whilsted, but when i hit it few times, now it doesent, it also seems it charging better now...i'm not kidding...

Keep an eye on it though. Usually the difference between a piece of equipment that is exhibiting high performance and one that is about to explode, is slight.

Buzzing AC / wall charger / adapter

Anyone else dealing with this? It was so loud when I went to sleep last night I had to get back up and hunt the room to find the source.
It's the wall charger. It buzzes when plugged into the wall, with or without the USB cable attached, but only without the phone ALSO attached and charging.
I come from a Nexus S and Galaxy Nexus and neither of those had this issue (nor any other wall charger for the myriad of electronic devices I've owned).
I'm not gonna reach around under the desk to unplug the adapter from the wall each time I'm done using it with the phone.
My usage scenario is probably really common in that I leave it and the USB cable plugged in, with the phone end of hte USB sitting on my desk. Plug the phone in to charge, otherwise phone is elsewhere. So, more often than not there is no phone plugged in, and it's thus buzzing.
Of course, Google can't or won't just send a replacement charger - they want to do a complete warranty return of the phone and everything. Such a major hassle for a small simple piece.
Does anyone know if the LG Optimus G has the same charger? I'm tempted to go to some local cell shop and try some other of the same charger to see if the problem is beyond my particular unit.

Happens to me too. As long as it charges I'm going to keep using it. If it goes I have a couple backups. I wouldn't return the phone though. Just pick up an after market charger and you should be fine.

Having the same issue, really annoying. There seem to be many faulty units...
But I fear they won't just replace them for free, because they are working well, just with this annoying noise. :S

IMO its just a charger. My phone is fine so if I have to use another I will. Walmart has some for like 10 or 12 bucks. But your right, charger shouldnt be faulty with that annoying buzzing sound.
Sent from my Nexus 4 using xda app-developers app

Mine does the same and its only when the phone is unplugged from it. It takes a little while to build up the buzz. Its like they used a low budget capacitor or something. Who knows..
Sent from my Nexus 4 using xda app-developers app

Same here, doesn't do it when the phone is plugged in so I don't really care. You can only hear it if you are right beside it.

Have the exact same issue with my Galaxy Nexus and Nexus 4 charger...

This is the 3rd nexus I've had due to various faulty reasons and all 3 have had the buzzing in the earpiece and an even louder annoying as hell buzz in the wall charger. The last 2 also have the rattle while the first didn't but I don't care anymore I still love this phone and will live with the annoyance. I don't really hear the earpiece buzzing unless it's silent in the room

Mine doesn't buzz, but squeals at a high pitch (15+KHz). It's not a constant tone, but warbles up and down in volume making it almost impossible to ignore. Swapped to the charger for an old iPhone one I had lying around. It only has a 1A rather than a 1.2A output, so it'll charge a little slower, but it's worth it to avoid the racket.

I am having the same issue is yours charging really slow some time I left mine overnight and it was around 25 :banghead:

Having the same issue as well with my charger. Very annoying. After I unplug it from the wall it still buzzes for about 30 seconds then stops.
Sent from my Nexus 4 using xda premium

Buzzing is just a capacitor inside charger.
When there is nothing connected capacitor is getting current, but with phone connected current goes to your phone.
Buzzing last even after charger unplugged because capacitor is like a temporary storage and gets discharged in few seconds.
Capacitors prevent power fluctuations, and help prevent ditect damage to device if there are fluctuations in power supply board.
Nothing to worry about it, many industries use capacitors to maintain their power factor (voltage/current) ratio.

Yep, experiencing this problem too. Personally, it's really annoying for me, the charger is just 30-40 cm away from my head when I'm sleeping.
I wonder if I could use another charger, I've one with OUTPUT of 5.0V and 700mA, that should be fine right?

Who's worried about it? It's annoying and obnoxious.
Person above: any USB charger is fine. The higher the possible current, the faster the charge (to a point, the phone will only ask up to a certain amount)

Yeh I have this on my UK charger.
It is recommended to unplug/switch off at the wall anyhow as a charger will be using power even when not connected to the phone.

An ancient 'wall-wart' transformer PSU maybe, but a modern switch-mode PSU will be using a handful of milli-Watts at most when idle. Not really worth unplugging to save power: home electricity is measured in units of 1kWh; at 10mW, you'd have to leave the charger plugged in for over 11 years to use 1 unit.

mine buzzes very loud too. both my nexus s chargers also buzz but not as loud as the LG one.

All the phone chargers iv used have got pretty warm when I've accidentally left them plugged in with no phone. They are using power so it just seems common sense to unplug (or switch off at the wall, which is what I do in the uk).
I'm not sure where you got your numbers but a quick Google found these :
the Lawrence Berkeley National Laboratory, who measured several devices in each category, a cell-phone charger draws an average of 3.68 watts when the phone is on and charging; 2.24 watts when it is on and charged; and 0.26 watts when it is just hanging out in the socket

I have the same problem with my Nexus 4 charger. Decided to use my Sony Ericsson Xperia charger instead.

This problem still annoys the hell out of me because my charger is next to my bed and I can hear it all night if I don't have my phone plugged in.

Turbo Charger - Electrical Noise?

Is it normal that my turbo charger has noticeable electrical noise when charging?
It has some volume variation depending on the phones battery level or what other device i am charging with it.
Its at my nightstand and it bothers my while i want to sleep. It gets louder if i charge something that's not QC2.0 compatible.
I stopped using it at night because its loud , but i am not sure if its okay or it has some problem.
Anybody else with his charger making noise?
My other charger are completely silent(chromecast adapter, nexus 7 2013 charger, iphone 4 charger, sony bluetooth speaker charger)
Only the turbo charger makes noise and its louder than i am comfortable with.

No noise on any of my 3 Motorola Turbo Chargers. I would have it replaced by moto

My Note 2 and Nexus 6 chargers both make a sort of high-pitched whine when plugged in. Come to think of it the charger on my electric razor makes the same sound as well.

yup, mine makes the noise, Google results pointed me to a couple reddit users who experience the same, so there of a few of us out there.
ah, damn quality control.

or maybe its a high pitch noise that most people cant hear, but a few with hearing sensitivity that can pick it up. generally, the yoinger you are, the more sensitive you are to noise in the higher pitch range. and gradually the sensitivity goes away as you age.

Finally someone else is having this problem as well. I mean i wish we didn't but it's good to know that I am not the only one. My first original turbo charger was making that noise too so i called Motorola and they sent me another one but that one is making a noise also which makes believe that it's something with a phone.

You either have really good hearing or something is not right with the charger. It will make a high pitched noise but it should not be that loud.

Mine will occasionally "whine" but it doesn't always do it. I have 2 of the Motorola 'turbo' chargers and both of them do it. Its more of a rare occurrence and it doesn't bother me. I bought a different brand one off Amazon that's coming today and can provide up to 30W (I doubt the nexus 6 supports the 12v turbo 2 output but i bought it for future devices). Has anyone else noticed that battery monitors don't reflect the accurate voltage? Mine always shows ~4.1V it could just be my turbo chargers.

Same for me. Thought it was normal due to the extra power output.

One would expect that to be the case. However, I just found mine doing it (it woke me up this morning) and my phone is fully charged. It made no noise while the phone was charging; so either it's only doing it under low load or on the 5v circuit, or my charger degraded overnight, the first night it was in use (I just got the phone yesterday).
Contacting Moto about this for sure.

I can confirm this issue using the EU charger. I didn't notice it until yesterday evening. When my phone was at 100% the charger started making noticeable sounds.
Any feedback from MOTO yet?

As a refrigeration tech I deal with low voltage a lot. Buzzing from a low voltage transformer, which is what you're charger is, Is no good. That usually means the coil inside is overheating. Sounds more like a defective charger to me. I honestly wouldn't even plug that thing in.

This exact thing just started happening to me. I am just hoping that leaving it on the charger isn't a safety hazard (for me or the phone lol)
Also curious to hear Moto's stance on this.

I noticed this 'whine' from the charger too tonight. Actually I found sounds like this fews days ago,but no idea where it came from, -- have thought it was from my notebook. Until tonight I found out the whine gone when I plug out my charger. and yes, that was when my phone got fully charged, will check out if it is there when the phone isn't 100% next time . . .

I've got the same problem. Has anyone performed a factory reset to see if the problem goes away?

Mine only whines on a cheapish wireless charger. No whine sound on my turbo charger or my tylt wireless charger. Been doing it since I bought the phone back in November. As far as I can tell it doesn't hurt anything.

I don't think the charger is a good quality or a safe one, strongly suggest you to replace a new one.

Yeah i've sent it back they'll ship a new one:good:

That whining you guys hear is just a voltage regulator vibration. It's not really something to be concerned about unless it gets louder. The same thing happens to graphics cards in a computer when they are under heavy load. It doesn't happen to all, but does still happen.
In my case with GFX cards, hot glue around the regulator that is vibrating has normally been a more than satisfactory fix. I doubt you guys will want to tear into your chargers to find the culprit.
Anyway, just giving my experience and knowledge.

Hi. I have this as well with my Moto X Play's charger. It is not so loud but it is enough to ruin my sleep. It only does it when the phone is done charging. One solution is going to the developer options and set it so that the screen does not turn off while charging, but this is probably bad for the battery as my phone is often very warm in the morning when I do this so I cancelled this and just resorted to not charging my phone when sleeping. It does not seem to be a defect, just something that went under QA or desing's radar.

How loud is the Samsung Fast Wireless charger?

Just wondering how loud your chargers are?
Mine is louder than my entire PC (which is pretty noise-optimised to be fair).
And the fan is on all the time while charging (ive heard that its meant to turn off when its not hot) .
I'm getting really annoyed by this charger.

A charger that makes noise??? I don't even hear mine. It's not a fast but regular wireless.

The fast charger has a fan in it, so its just a regular fan whirring noise.

It's really quiet, I get more "coil noise" from some of my other fast chargers. My Surface Pro 4's fan is 10x louder than the Samsung Fast wireless charger, so unless there's a jet turbine in his I doubt it's that loud.

Ah thats a bummer. I guess mine might be defective :/

I am using new series S7 but it charger is not best

Hear it occasionally but the fan only seems to kick in when it's warm.

my charger is loud too but only whet it connected to fast charger adapter. when it connected to regular adapter thet it has no noise at all

My Charger barely. works it doesn't really charge that fast either. I wonder if it will work with Dbrand skins.

Does it say 'Wireless Fast charging' on the screen when you place it on?
Are you using the fast charging cable/wall adapter that came with your phone?
I'm using a spigen neo hybrid case and fast wireless charging works fine (and very quick too)

Yea it's a Samsung fast wireless charger and I have fast wireless charging turned on. It works when it wants to its just not consistent.

Just as an update. I have 3 now. Two from the same seller. One from a different seller. All appear to be legit.
All 3 are quite loud. One in particular i think is broken because of how loud it is
All have the same sn on the actual charger. rf7g80ag77acis
The box for #1 and #2 have differnet numbers, but #3 has the same one.

I am using a Samsung USB Power Plug.Do you have tried another?Tell us the bad thing so that we could avoid being defrauded:good:

I dont have another plug to try unfortunately, and the wall chargers are quite expensive.
I'm starting to think all these ebay chargers are legit, but maybe not A+ stock. Maybe the fans are loud (all 3), or the paint is peeling a bit (two of mine)
Totally guessing here.
I go into wayy more discussion plus photos over here: https://forums.whirlpool.net.au/forum-replies.cfm?t=2525674&p=-1&

I am using it. The fans is extremely silent. No fans spinning sound.

How can you assure it is legit. Plenty items in ebay is not legit. It looks legit doesn't means it will be.

Someone on whirlpool took one apart, along with a legit one. Components inside were identical. Also the weights matched. Packaging was identical, fast charging works perfectly (confirmed on all three of mine).
There are a lot of fakes on eBay I agree. But they all cost $15 or so. The ones I purchased were $40 and $50 from sellers many others on whirlpool had purchased from
And in reply to the guy who said the fan doesn't turn on when not using a Samsung fast charger adapter.... Yeah that's by design. Same result by switching off fast charging in the phone settings. Fan doesn't turn on

Do you have a link to the teardown? I'm interested to see what's inside componentwise.

Don't mean to derail this thread but instead of creating a new one. I've been meaning to ask: does your Samsung fast wireless pad not turn off (blue lights are still lit up) after charging your phone to 100%? I've got the proprietary standard wireless charging pad but it automatically shuts off once done charging my phone. I'm suspecting a problem with the former but would like to be sure so I went ahead posting it here..
Thanks in adVance!
