Hi. I just bought my Sensation from Amazon UK and I plugged it in to charge with the stock charger.
After a while a high pitch sound was coming from the charger. Is a very annoying sound. I thought there is a problem with the charger and I tried to charge my Xperia X10 with that charger but with Xperia X10 I do not hear the sound.
Then I charged Sensation with Xperia X10 stock charger and I hear again that sound but much less than the HTC stock charger (I have to put my ear near the Xperia charger to hear it).
With the HTC Stock charger the noise stops when I switch on the screen. When the screen switches off again that noise begins.
Anyone knows why? Is this normal with new smartphones? Maybe they charge faster and they require more current?
Hmmm...
I get that with my 3rd party iPod charger too... not too sure of the reason...
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.
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 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?

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
Well I tried it and it worked but I'm worried about the voltage. Will the speakers draw too much power and ruin the charger?
Here are the specs of the charger and the speakers and you tell me if it's safe or not.
This is what's written on the box of the speakers.
