Hey all, after I unplug my phone from the charger, the charger starts to buzz. I can unplug it, and it will continue to buzz for another 30 seconds or so.
Is this normal?
If I recall, the Nexus 4 charger did this as well. I haven't had an issue with mine so far, but I've heard others haven't been so lucky, so take it with a grain of salt. As for the noise itself, it sounds like a capacitor dispersing it's stored charge, it just happens to be a bit noisy in doing so.

Mine is doing the same thing as well. However it is also making noise while it is plugged in. Does anyone else have these issue?

Yes, mine too.
It makes the buzz also if the phone isn't connected.. I don't think it's a real issue, but I'd like to know for sure!
Charger is buzzing when you unplug your phone because energy is stored in it, and doesnt have a way to go out. If you unplug charger from a wall, it will start to fade that buzz because it doesnt receive any energy and it can dispers. But its really strange for it to buzz when its connected to phone.. But if it charges normally, no worry.

Well ladies and gents, I think either my eee pad has been sucked dry or the charger fried, or both. I went to turn on my pad and found out that both the dock and tablet were at 0%.
I plugged it in got it booted and after an hour, the orange light on the side of the dock stopped blinking and stayed orange, as if it were charging, but the pad still showed at 0% for both pieces. I unplugged the charger to find it was so hot it was almost untouchable and as soon as I unplugged, the tab shut down. Also the dock was not usable to type while plugged in. Am I screwed with this piece?

Zip lock bag your charger and put it in the freezer.
lol really? put it in the freezer? Hey test the usb cable first by connecting it to the computer and see if you get a response. If so for the most part you have like a 90% chance its not the cable. More then likely the adapter is messed up as stated above. The AC plug itself is detachable, its hard to get off but it comes off. You will see its two pieces one big piece and a slimmer piece. Dont rember witch direction it SLIDES off but it comes off. Just check around it and make sure its not blocked or anything. But yea might have to get a new one.

Really. There is a heat sensor in the charging cube that disengages the link in case of overheat. Zip lock bag is there to keep out moisture.
Crazy. I unplugged the charger, let it sit. Plugged it in 20 mins later and all of a sudden my tablet has 60%. This thing is weird. Gonna have to teat more thoroughly ans possibly get a new charger

Good. Just remember. If this happens again but next time the safety won't just disengage, then throw it in the freezer like I instructed.
Added by edit.
Then of course chances are you won't do this. Most people are not modders because they are too afraid to do anything out of the ordinary. This is why the ipad is so popular. Anyway, if this is your case, then I guess the alternative is to get a new charger.
I just want you to know that i tried Goodintention's advice and it worked for me. That being said, do not wait to get a charger replacement by following DevCake's thread on how to make up your own charger for the TF. Once these chargers start going bad the only way is downhill.
My second charger died yesterday and I am following Devcake's advice.

Curious. I've been charging it through the USB/Electrical outlet charger overnight and have yet to hear a beep.
Also, when I plugged in the micro-USB cable to my USB port the charging indicator went on, but even though I left it overnight it didn't charge. Has this happened to anyone else?

I haven't noticed it beep at all. And that seems a bit odd, have you tried using a different charger/charged anything else on that charger?

Yeah, I don't think it beeps when it gets full which might be an oversight. I've never had a phone not do that before.
As far as charging off the USB port, I was trying to charge off a powered USB hub, and the phone clearly indicated it was charging (even though after leaving it was mostly empty). I'll try charging it off my PC's USB port and see if that works- only thing there is that I have to leave my PC on to charge it though.

I'm the opposite -- I've never had a phone that's beeped when it's fully charged. That would be annoying. The Nexus 5 doesn't beep when it's fully charged. If it did, I would find a way to disable it! It would disturb me at night!

I think the beep when charging is a Samsung thing. I had a Galaxy S2 and S3 and they both did it.
I hated that feature so much! It was the only reason I had to mute my phone at night. I'm pretty sure if I plug in my phone over night it will fully charge, I don't need my phone to wake me up in the night to brag about it!
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
