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.

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.

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?

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.
I've had the Droid 3 for about 10 days now, and I've been encountering an intermittent problem with charging the phone.
Last night, I plugged in my phone so that it would charge overnight. I made sure that the connections to both the phone and the outlet were firm, and upon plugging it in, my phone's battery icon and lock screen both indicated that it was charging. However, when I woke up this morning, I discovered that the battery had actually continued to discharge overnight. Despite this, the battery icon and lock screen both continued to say that the battery was charging.
I've run into this problem three times this past week. It's entirely possible that I just have a defective device, but I wanted to check and make sure that nobody else was experiencing this issue before taking it back to Verizon.
Check the task manager for programs using lots of cpu. I've found that using google maps nav in the car dock while charging still in fact uses more power than it could charge. Your issue is with the screen off though so check for background apps.

I have had this problem 2 times and I have had the phone for about the same time. I plugged it in at like 40% watched a movie screen never came on till the movie was over I looked at my screen and the battery was at 11%. I was thinking maybe just a bad connection untill I looked at the notification bar and it said it was charging!
I just got my Droid 3 yesterday and last night, the first night of use, it did the same thing. Even if I go into battery usage and look at the graph it'll say charging but the power level will be going down. Very frustrating.
A Verizon rep I spoke with recommended trying a different charger. Sounds reasonable enough, so I'll give that a shot and post back after a few nights of use.
What is the current rating of the chargers you guys are using? (i.e. 850 mA, 1 A, etc). A good rule of thumb is not use anything less than 1 A (1000 mA).
The Motorola-supplied charger is 850mA.

This sounds logical. I had this same problem two phones that happened to have a slide-out keyboard (Shift, G2) and the problem vanished when I used a different charger. I just read today that 100s of people were having this problem today in a news feed.
I was having the issue too, so I used a 2A charger that came with my Huawei tablet...no more issues! (Charge time is about 1.5 hours too!)

I'd be careful about using higher amperage chargers. Don't want to be burning out the charging circuitry. Not saying you will.. just be careful using a charger not designed specifically for the device.
Apparently the new Moto LiPo batteries have another level of overcharge protection. To be safe, I'm going to use an ohm-meter about once a week or so to check the internal contacts (a higher ohm rating would suggest damage).

That's not the one I have, I'm using the USB-output charger from the S7 SLIM, then the Moto supplied USB cable.
Well, it's been a few days, and I haven't experienced the problem since switching to a different charger. Granted, the problem was intermittent, so it's difficult to know for certain if the charger was in fact the issue, but I'm content with this solution.
I've been using my iPad's 5.1V 2.1A charger without issues for a few days. It charges the extended battery from 10% to full in a little over an hour.
That's the dual-core proc for ya. Wonder why the Xoom uses a proprietary charger? dual-core devices nom battery.

No? Dual core is more efficient, it shuts down one of the processors when it's not in use. Dual core means nothing about power efficiency. As a matter of fact, it can have an advantage. Each core uses less power, and combined, they can use less power than a similarly powerful chipset.
I've also run into some issues on my 5 day old Droid 3. It seems to be when disconnected from the charger. I have two regular Moto chargers for this, and tried a 1A HTC charger, which this thing will not charge from.
I tried using different micro USB cables, which didn't help, either. I was trying to move the phone around while charging, and seemed to encounter the issue. Either it's a connector issue for the mUSB, or the (especially short and stiff) charging cables have broken conductors inside, and we're getting a bad batch of cords.
Possibly the D3 has its own issue with charging, but I didn't have a problem until this morning. regular mUSB cords won't work for me at all, as I've tried all I have.
Given this issue, I'm wondering how widespread this is, and if it's something to take the phone back for. I took me a few hours (over 3) of waiting and fiddling with it, but it's at least charging now.
I had this issue to. I used a different charger and cord to charge my phone at night woke up the next day no charge. I went to work pluged in to my wall charger and still no charge. I did a factory reset thinking that might work but it did not. I was going to take it to a verizon store after work so on the way there I pluged in to my car charger an it started to charge so I skipped the store. When I got home I used a different cord and wall charger and it also worked. I did notice that when I plugged in the night before that a small little white light was lit up for a second in between the charging port and hdmi. I know there is a light there but never seen it light up before. So maybe that was behind all of this. Not had a problem sense.

The amperage you see stated PS units has no effect on your phone. That's not how many amps leaves the unit to charge your battery. That's how much the PS unit can handle as a draw. In reality the reason the stock ones are only 850 only means that the manufacture used spec parts for the PS unit. i would think that Motorola's minimum spec was 850 and so that's what the PS units manufacture used.
The higher the number means nothing other than you can bet the 1AMP one is going to out last the 850.
Of course the last statement is highly speculative because i have no idea what the amp rating for the phone is. But what i do know is that all the parts are made in china and you can bet they are not going to overbuild anything.
If the amp range is 675-832, which is the number I would expect then if the phone draws more than 850 for an extended period of time the units internal fuse could blow. Unless of course you purchased a third party unit that has an external fuse. Then you can jsut replace the fuse and not have to worry about going out to buy Chinese garbage. lolz
but then again i bet this Droid 3 is made in china, oh well. I like it anyway
My charger seems to emit a very high pitch noise that increases as the phone has been charging for a while. I am using the stock Samsung charger for the Galaxy Note with the included UK adaptor.
Should i be concerned that the charger is emmiting these noises?
Are these noises caused by the capacitors like in desktop psu's?
Can these noises cause any damage to my Note?
Do your chargers make this high pitched noise?
Many thanks

I wouldn't worry. Modern chargers like the one with the Note, use switched-mode technology, like a pc PSU. Basically, instead of using mains frequency AC conversion in a transformer (50Hz, big transformer), the system uses high frequency (15kHz+) transformers, which can be much much smaller. A vibrating transformer is all you can hear. Not all chargers do it, you're just unlucky. Giving it a tap may or may not help. If its annoying, you could always ask Samsung for another. I change all my wall chargers and PSU's in my bedroom for switched-mode ones as I can't stand the 50Hz humming through my bedside cabinet.
You could always think yourself lucky that you can still hear these frequencies, it's an indication of healthy hearing response.
If it wasn't for this fantastic bit of technology, our power supplies would be bigger than the phone, and PC PSU's would be too heavy to lift without breaking Health and Safety regulations!
I digress sorry lol

Yeah.. using high frequency has an advantages.. You can reduce the size of the transformer and eventually your charger size.. I still remember my Nokia 3330 charger which works at 60Hz.. it was a huge charger with small capacity.. lol
the transfo should not be correctable by tapping it, the windings should be firm on the transformer itself, the sound you hear is most likely a crappy capacitor used in a bridge to get AC to DC. I have the same sound about 15kHz coming from a hair clipper charger when the clipper is first being charged. load (I) may be too high for components. try turning your device off before charging, see if the sound is as pronounced

I have the same problem on my S4 mini but it's pretty annoing!

Hi I've just got the galaxy s9 today and while it's plugged in charging I can hear a very high noise almost like when a computer is "thinking" really hard it's coming from the phone I believe not the charger plug, it sound like a tiny mouse is stuck inside my phone lol an ideas how to get rid of it? I'm using the fast charger and cable that came in the box with the phone, any help in simple terms would be great thanks
This is a reply to a very old post, but I also discovered that a Samsung fast charger (not wireless) emits what I would describe as interference to my portable AM radio, when the charger is within several inches of the radio. mind you, the charger is unplugged from the wall outlet, and is without a charging cable. This is probably a product of the switching supply circuit, and happens within about 60 seconds after being unplugged. As soon as the supply voltage in the charger drains to zero, the noise goes away.
Most active devices have a period of time after power is removed for the voltage inside to reduce to zero, that is why it is recommended, when power cycling (power down then back up) to wait 10 seconds for the voltage to go to zero before plugging back in.
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.

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.

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:

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.
Sent from my Nexus 4
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

mine doesnt make any noise. i think motorola only made yours that way? you should probably get it replaced.
Mine does that since it was new. It's right next to my bed and it sometimes gets annoying at night, but not worth the hassle of replacing. I've had no issues charging.
Mine does the same, it's plugged into one of those 3 outlet splitters if that's any reason. But only everyonce in a while
Mine only does this when I charge it wirelessly . I hear a loud squeal for about 15 seconds and then it goes away.
Any sparkies looked to see if its cheapass caps issue? Only other thing I could think of is since its a quick charger there is some other half assed component in there since I think it adjusts voltage. Oddly this is the first walwart ive had that did this.
I swear a squirel is gonna jump out my phone motorola.
It does on mine and it's annoying when I'm charging it at night next to my bed. I just use a 5V 2Amp charger for overnight charges.
I have quite a few chinese power adapters for boards with coil whine.
My moto charger is fine though, I would expect they are higher quality and coil whine wouldn't be too common. Try for a replacement I guess.
Same problem. And there is already another thread about this issue...
Mine is making noise when my N6 is fully charged - otherwise the charger is quiet.
