Hey there,
I've owned three nexus 5's and I just bought a 4th and I notice that the back makes a slight buzzing sound when charging. I know the LG wall chargers make a sound but this is coming from the device itself. Only happens when charging and the phone keeps a good charge so I don't thinks it's a faulty battery.
Sounds like it's coming from the middle to top part of the rear, where the battery connects to the logic board. Could it be a faulty battery, just a transformer or something more serious?
Also I left it charging for 7 hours overnight, no issues.
Thanks in advance
Anyone?
For me it has no noise while charging, but the charger gets very very hot. Pay attention to your device while charging, check if the device or the charger temperature is higher than it was supposed to. For me the charger might get to 70ºC, it almost burns my hand sometimes mainly if charging 2 devices at once.
Have you tried plugging in a headphone to it and see if the noise goes with the audio?

The charger is fine and the buzzing/humming sound isn't coming out of the speaker, it's coming from the rear of the phone itself. Temperatures for phone and charger are normal.

I have a power plug and sometimes charges and sometimes don't. It also gets hot after about 10mins of charge but it is charging.
I know there has been a few faults but has anyone experienced this charging sometimes and hot to the touch?
The charger getting hot is a good sign; that shows that it is working. The charger will get (very) hot during charging and will cool off when it is done charging.
My recommendation to fix the sometimes charging/sometimes not charging problem is to pull the cord out of the plug unit and plug them back together. The cord is a little finicky and so it might need to be reseated. Make sure the cord is plugged ALL the way into the plug unit (it can be a little hard to get them to be perfectly together).

I have called Asus on this issue and while they agreed to RMA the charger I just can't be without it right now so i wait. Chargers getting warm are normal, but chargers getting as hot as mine does is not normal and not good. I would estimate this charger is getting in the 160-180 degree range. Mine has also failed to charge on one occasion. One post i ran across said to change the polarity of the charger by turning it over so that the word ASUS is upside down when the viewing the outlet with the ground pin below the prongs. Seemed to help but not sure if its actually better or just wishful thinking, ymmv.

Turning the charger over does not effect the heating of the charger, it simply eliminates the possibility of stray AC voltage on the shield of the cable and frame of the TF. The heating of the charger is caused by inefficiencies in the inexpensive charger and fact that it appears to be working close to its design limit. A few tips that have worked for me.
Use an outlet that good air circulation around it.
If used on an extension cord. sit on a heat conductive surface not on a carpet.
If tablet and dock are deeply discharged, charge separately and allow charger to cool between charge sessions.
If the charger gets too hot, it appears to shut off. Allowing it to cool generally gets it going again.
ASUS said i spoilt the power plug
sigh...i bought 2 units of EEE PAD **** TRANSFORMER...2 of the power plugs also loose...after 2 weeks of use...they said i spoilt the plugs and is not under warranty..i need to buy replacement...
how low quality is ASUS product or eee product...????

The charger and plug for the wall are a 2 piece unit. Ensure that that end that contains the wall prongs is seated all the way down. There is a line between the 2 units. The pieces on both sides of the line should be flush.
Regarding temperature, mine gets pretty warm. Warm enough that I would not want to handle it.
Anyone having issues with your touch screen when you are using it while it's chArging? Just wondering if i have a faulty device or are there others with the same problem

No my device does not have this issue when charging. I think this issue has something to do with the charger.
That's a grounding problem, had it with my SGSII try a different cable.
The sensation had an issue of touchscreen problems while charging. i went through 3 phones. The cause is the same cause as the wifi errors that people are having with the HOX. Bad connection from unibody(sensation) to board.. If we added aluminum foil or solder (just like the HOX wifi issue) it would fix the problem. On the sensation the problem got really bad to where you couldnt unlock the phone with the lockring. grounding issue. I hope the HOX isnt having that same issue and you just have a bum phone or better yet a bum cord or charger. let us know if its either
yeah happened alot on my s2, was due to usb cable or something
but works fine when im charging
It was the grounding issue, does this damage the phone? I have a wall outlet with USB ports so it might emit too much power

Every time this has happened it has been because of what the USB cable was plugged in to and not the cable itself. Try the charger it came with in a regular plug. If it doesn't work better then it is a phone problem.
This happens to me too. Charging from the laptop with an eBay (chinese) cable causes the touchscreen to be unresponsive.
Here's how to test: Open the Notes and draw a few lines very fast.
Here's the results:

Here is a video of it happening to me on my skyrocket. It was because of the charger. Try a different cable, then a different wall adapter.

It is because of the charger...it's always recommended to use the charger that came with the phone eventhough they give us a tiny a$$ USB cable.

Yes, I have an issue - when the phone gets to 90%+ while charging, the screen becomes very unresponsive. The drags don't drag - instead the touches are registered as taps.
You can get an app like MultiTouch Test - and you will see, it's very clear to see when this happens.
My first One X device did not have this issue, so it's something specific to my current unit. Doesn't bother me much, since it only happens at 90%+ charge, while plugged in...

To me it doesn't happen all the time, sometimes it happens, sometimes it doesn't. Unplugging the cable and plugging it back in seems to temporarily fix the problem, if I leave it charging for a couple more minutes, I think the problem will come back, but again, unplugging/plugging it back, solves it temporarily. It's weird...
Oh, and all this to say that I observed this behavior while charging around 65%, not 90%. And I've only observed this while charging with AC power with the original cable and charger. The problem did not present itself (yet) while charging through USB.

I just had this happen with the stock charger from my old HTC One using it on my HTC One X. Along with touchscreen problems it got VERY hot located as you are looking at the camera side it got hot on the top right side near the camera. Dunno what that could be. Both chargers are rated at the same voltage and amperage, I dont get it

It's caused by electrical noise. The voltage supplied from your mains outlet is alternating current (typically 50/60hz in frequency). a usb charger has to do two things; firstly step down the voltage (110v/230v/240v down to 5v) and secondly rectify the alternating current into direct current (positive and negative). how it does this is by using a transformer which employs an iron core surrounded by copper windings, this generates a lot of rf (radio) which travels down the cables to the device as well as broadcasting a short distance through the air, a decent charger will use shielding as well as a few other pieces of circuitry which will neutralize the rf given off. In order to rectify the voltage the charger will use a variety of diodes and capitors, in a cheap Chinese charger they will typically use as little as 2 and possibly a generic chemical capacitor (similar to a small battery) these degrade over time and can get quite hot, fat and eventually burst - when you hear about chargers exploding or setting on fire it's usually because the capitors aren't up to the job. a Chinese charger may have all the quality control and certification stamps but most of them are forged, if you buy a charger for less than $10 this is what your likely to end up with. the outputted voltage may appear 5v on a multimeter but they are a very dirty output and can spike from 3v to 7v or even more the load on the charger increases. The dirty output interferes with the mechanism used on touch screen devices which also employ a type of capacitance to register where you are pressing on the screen. A decent charger will use solid state capitors and which should last a lifetime.
if the smartphone miss behaves whilst charging 90% of the time it's because of a faulty charging device (or one employing poor components). a decent charger may cost more $20 but they are significantly safer for both you and the device.
The problem with mains sockets with built in usb usually comes down to shielding, they will either have none or be earthed (which might sound like a good idea but in practise a lot of domestic devices will create leakage to earth causing more noise - alot of studio equipment will have a separate earth). These may not be as dangerous as cheap Chinese chargers but still undesirable.
If a original or good quality charger isn't available one of the best sources for charging a phone will actually be a desktop pc with a usb3 port. The whole pc is insulated in a nice metal case and there are a plefora of high quality components to create a stable clean power supply (a cpu voltage tolerance is usually measured to 2 decimal places of a volt which is pretty good).
Ditch the rubbish cheap chargers, you honestly get what you pay for and they aren't good for the long term health of the phone. If it hums or makes a high pitch noise whilst plugged in your playing with fire - literally. they aren't bothered if your phone dies in 6 months or bursts into flames so long as they get the $5 x 100,000 people who buy them (these things literally cost pennies for them to put together, even though the case might look the business inside they are nasty and as cheap as)

Very insightful. The worst part is that I have two original HTC chargers and they both emit the high pitched noise.

Some of the very small chargers might whistle a little, its called coil noise and isn't as bad as capacitors about to pop. The iron core hasn't been sufficiently dampened or glued into the case so it resonates when the ac passes through it, the pitch may change depending on the voltage (whether its a 230v or 110v power supply). It isn't unsafe but HTC should be doing a better job at checking the new chargers, over time most chargers will develop coil noise as glue tends to melt or degrade.
Very insightful video, you'll never buy a cheap charger again

The gist being the cheap chargers could very well set on fire and the USB could go live at mains voltage with no circuit protection, death traps spring to mind. Be careful what you buy.

So I just noticed that the wall charger that came with my Nexus 5 makes a quiet buzzing noise when plugged into the wall socket... It does it even when the phone is not plugged into the charger. Does anyone else have this issue??
I find I hear it most clearly when the phone isn't plugged in. But yes, I believe this is normal. Mine does it as well.
mine does the same thing. sadly though that is a sign of non top of the line caps.
Hi
I brought a Samsung wireless charger. The first few days, it worked flawlessly, but today when putting the phone on at 27%, when it hit around 85-90%, it started saying "Wireless charging have stopped" even tho it still charges. It's annoying, cause the screen light up, it vibrates and I get notification about it, but it starts charging right after?
Do you think this is a phone or wireless charger problem? Also, will this hurt my battery in any way? I mean if I leave it overnight, would it hurt the battery that the battery start charging, stopping again and then start again? This is around every sec or so.
Thanks in advance
Sometimes, that charger is finicky. You need to position the phone just right, and if it slides a little bit, it can start connecting/disconnecting. When it does that, try just picking it up and setting it back on the charger. I try to put just above center on the phone over center of the charger.
samsung S Charger Wide works
I bought the Samsung S Charger Wide qi charger, it predates the S6 round charger. It's also cheaper, although it does not come with a plugpack or USB cable. It needs a 2A charger (such as the one which comes with the S6). It charges easily even with the Samsung S View case in use. This older charge is about the size of Note. It has a slight lip making it harder for a phone to slip off.
does wireless chargers is fast as the fast charger provided?
No. It is a lot slower although the difference is much greater if your battery is very depleted. The performance gap is lower as the battery charges because the fast charger 'slows' down.
It's charging at 927mA according to GSam Battery at about 80%. That's not too bad.
I got the phone for awhile,
the phone itself is running very well.
but i have another concern,
i start to hear the super charger when it is idle (not charging but plugged into the wall)
when it is charging, it is completely silence.
Do you also hear the noise from the charger too?
Can't say I have noticed that. But I always turn chargers off when not in use. It's safer.
I sit close to one at night, in total silence, and I can't say I've ever heard any noise coming from it.

Yeah, I heard it too. I have two chargers and both do the noise.
What kind of a noise? Like a humming sound? Electrical buzzing?
Sent from my MHA-L29 using XDA Labs
Better call them Ghost Buster folks.
On a more serious note, never experienced anything like it. Turn off your charger when you're not using. Better charger life longevity.
This has been a thing with LG chargers for years. For some reason they just hum or buzz.
I wouldn't worry about longevity tbh. Any good quality charger will largely outlast the device it hooks to. Heck my 1995 Motorola Flare charger still works.
If the buzzing gets on your nerves you can always get one of those cheap socket adapters with an on/off switch (see attached).

I used to get that on my old Samsung chargers. Never heard anything with my mate 9 charger tho. I wouldn't worry about it if I were you.
Thank you for the input for using a switch to turn it off when not using...
but the most important point is, i have a friend who also own a Mate 9, his charger is dead silence when charging or idle.
The sound is more or less like buzz (but very little sound)

I can confirm your charger noises. Wired thing. Better unplug the charger, because noise means it is burning up energy!
Not to be dumb but is it your outlet? Have you tried a different one? Mine is completely silent

Notice this as well one night while reading on the phone in bed. Mine does it with or without charging. I've also experienced this with a Sony adapter, and Samsung. I have a few devices plugged into a 8 prong switched grounded outlet... I just flip the switch off in the morning and this this actually lasts until bedtime??

Phone chargers are step-down switching power supplies.
They are called switching power supplies, because electrical current flowing into coils or capacitors is always switched on and off to get a desired amount of electrical energy saved inside this energy storages to get lower voltage than the power line. They are verry efficient and much smaller than conventional ones.
Because of the current switching the plates of the capacitor or the windings of the coil can vibrate and cause this sounds.
It depends on the components if there is a sound or not and can vary from batch to batch.
So no worry if the supply creates silent noise, its working fully, only different components are used! (as long as it is no super cheap china power supply, they could be very dangerous)
And i think the power supply lives as long as the phone. Computer or TV power supplys are always plugged in too and they have the same technology.
But i always unplug the power supply to save enegy
