Help noise coming from wall charger

[dixonba]

I guess I got lucky. Maybe the key was to identify the sound as capacitor whine instead of just a weird noise.

I'm charging mine up. Hopefully it will make the noise so I can swing by the store tonight.

New phone. Charger does not make the noise. We will see if i have better battery life over the next few days.

My new charger and new battery finally arrived. The battery life is almost 2-3 times more. I wonder if the "capacitor whine" damaged something on the old battery?

Went to a very large store today, regarding this and he could not hear the issue even though I had it charged very high to the point where it usually occurs, I even waited around the charger and never heard it myself. Maybe it was just bad luck. He did tell me his does the same thing and it does not effect the battery. I have ready online some chargers do this and it does not cause any harm. I'm not worried about it.

My wife took my charger in today but the tech could not reproduce it. I will have to go in there with the phone when the phone is between 90-100 percent as this is when it normally happens for me. I agree that it most likely is not doing any harm. My high-end video card in my computer also has a capacitor wine during certain heavy duty operations. Some people fix this by coating the capacitors with resin or glue. It's just annoying when you hear it at night when you are trying to sleep. (I work for a hospital in I.T. and must keep the phone next to me every night). Guess I might have to start charging the phone in the morning at work.

Does anybody notice that sounds stops when the LED is green. Last night I placed it on the charger and noticed it started making the noise after two hours. This is about how long it takes to fully charge from 25%. Although I still had a red LED.

I left it alone and the high pitch lasted about 20 minutes. That is when I noticed the LED was green and the noise stopped.

This is what happens for me and most likely everyone. The capacitor isn't working as hard once the phone goes "green" so it stops resonating.

I went to the store and the tech reproduced the sound. He just game me a Verizon wall charger. No more noises. Hopefully it didn't do any harm to the phone.

Wow... Now I've heard everything "Capacitor Whine". This noise is actually a fairly common noise in newer "switching power supplies". Capacitors store energy, they do not "Work Harder"...

LOL WOW indeed! Are you sure that article you googled is talking about "audible" noise?

 

[highvolts]

Nope just skimmed it lol but there r ones out there

EMI is different than an audible noise. Now I'VE heard everything.

"HEY HONEY...YOUR EMI IS GIVING ME A HEADACHE"

Hi pitched whines coming from wall chargers is nothing new. I have never researched the actual cause/reason for the whine, nor do I know if or what sort of damage could result from using a "whining" wall charger - I've simply not used a charger of mine that whined (I've never had it happen where I didn't have another charger to use instead).

 

[dazeek]

mine makes noise too. The vx rep coulda cared less. If anyone got theirs replaced i'd love to know how.

 

[dixonba]

Call customer care and tell them that your charger is faulty and is making an audible capacitor whine. Tell them you are worried about it damaging your phone.

 

[dazeek]

ahhhhhhh peace and quite. I called vz and they shipped a waller charger out for free. Works like a charm....no more high pitched annoying sounds

My charger whines when the phone is almost or fully charged, not when I first plug it in. It also doesn't do it all the time, so I will pay attention to which way I plug in the charger. My old LG EnV2 charger works just fine with no whining at any time.

So my wall charger also does this clicking when it's plugged into the socket, but not phone. After it's connected to the phone the clicking stops with a really quiet high tone ZZZzzp. After that no sounds. Also if i unplug the charger from the power socket while it's making clicking sounds it will keep doing them for maybe 5 mins or so until it runs out of power. Quite interesting sound, but doesn't seem to be dangerous.
