I had been in the habit of charging my phone overnight with the phone beside my bed. This is now impossible with the GN2 charger as it emits a tortuous, uncomfortable high pitch squeal particularly near the end of the charge.

Mine doesn't make noise when it is actively charging. I might hear the pulses for a minute after it is done charging and it's trying to figure out that it has completed charging and the light turns green. Then I unplug it when it is done. But I unplug it from the wall first then 2 seconds later I unplug it from my phone. This way, you avoid the ticking noise. It has trained me like a pavlovian dog to save me money...even though it is probably a few cents a month.
Yes, some people had reported of a buzzing sound from the charger. Go get a warranty exchange if you want cos not all charger unit have this issue.
I use my PC to charge mine. It's slow but, I sleep 8hrs, it's usually charged by the time I wakeup.
warranty. end of problem.
My charger squeals in some plug outlets and not on others. I think it may be a grounding issue. Try plugging into a different outlet or into a power strip and see if it still squeals.

Not had this issue myself and have the charger by the bed, will listen out for it. as other have said you may have a dodgy charger ask for a warranty swap out.
Yeah... My S2 charger emits a small high-pitched noise after being unplugged. Best way is to remove it from the wall first, and allow the phone to draw off any residual charge in the capacitors.
I'd imagine that something is a tad leaky in the rectifiers... If it's a really high frequency, it's possible you're hearing the actual pulsing of the mains supply coming through (these power supplies work by rectifying the mains supply, then inverting it. The inverter should operate above 20 kHz so you don't hear it. If it's "faulty", it might operate at less than 20 kHz?

Got absolutely no problems with my charger here...
I experienced the exact same thing with a charger before (I haven't even tried Samsung's yet). My wife can't hear it, it drove me insane. Woof woof I guess...
The high pitch noise has nothing to the with your phone. It is caused by the converter inside the charger. Since the chargers these days have to be cheaper and cheaper, inferior products are used sometimes. Try using an older micro-USB charger (I'm using one from HTC), or a standard 220V adapter stick with a standard USB-microUSB cable. And not all chargers are equal, not even if they are from the same manufacturer.
One of these will most likely restore your sleep

Hi,
Any of you feel that there is electric charges on ur ear while charging when making a call? when i disconnect the cable it is okay. only on the receiver portion. could it be a faulty battery?
I've not experienced that issue, but then again I've not tried using the phone during charging.
Are you charging from the mains charger, or from a PC?
It is most probably a small amount of electricity "leaking through" down the cable from whatever you are charging it from.
This might sound a bit scary, but is not necessarily a danger or even a fault. PC power supplies in particular have components to stop EMC (radio interference) that can sometimes cause a bit of this "electrical leakage".
If you are using the supplied charger, make sure it is not damp or wet, as this really could be a danger.

Hi,
I am refering to the charger. using PC is okay. i tried with different power point still the same. no it is dry. shld i go to the service center
I just tested the electrical mains leakage current from my own charger.
It's around 15 microamps, probably not enough for most people to feel but maybe on a sensitive part like the ear it's possible. I think that the CE requirement is 250 microamps maximum so it meets statutory requirements.
Obviously I cannot tell whether there is a fault in your charger, but if it was mine and the current was not actually uncomfortable, I wouldn't worry too much about it. I would expect genuine HTC chargers to be 100% safety tested.
i did notice the same from mine while using the wall charger.. on my hand tho not my ear.. more than once.. kind of weird.. but w/e haha
Yes, I have had 4 HTC phones for myself and every of them has done it while on wallcharger. It is kinda annoying when speaking on the phone.
Wizard did it really much and couldnt sometimes talk on the phone same time.
2 Diamonds did it, one i use now has invisible shield so it kinda stays in them because of rubber
HD does that but not much or not at all.
Maybe it is because of aluminium or metal casing on phone like wizard and Diamond, havent yet tested HD much. Got it yesterday :>
Hi,
so it a norm for all HTC device? so it is not faulty?
thankx
Hi everyone,
I noticed that the original battery charger (wall socket to usb) makes strange noises when the phone is charged. It's very quiet when the phone is in standby-mode but when the display is on it becomes louder. It's an alternating buzz -it comes and goes- sounds like a circular saw. Make it impossible to sleep while the phone is being charged.
Do you have similar noises or is mine just broken?
Yes.. i hear it too...

Anyone else, please?
It's the LEDs. If you turn of the charging LEDs you'll get rid of the sound. At least mine did. I was trying to sleep with it charging next to the bed and got annoying as hell.
Me too, I think it came from the charger.
mine has absolutely no noise at all whehter I turned on LED or display while charging using the wall charger.
yeah mine squeals too in time with the leds it worse when the phone is charged
You guys should not worry, it's a normal "issue" with electronics. Most Intel-based notebooks have it and a lot of chargers make the same noise. It's usually always there just barely audible, or you may not be able to hear the highest frequencies.

Yeah, I guess you're right. But it's very annoying since I charge my phone over night and it has to lie next to my head because it's my alarm clock too.
I don't charge a notebook in my bedroom over night, therefore it doesn't bother me
But I tried your advise and switched off the charging leds -it became better after that! Thanks!
mine does not make any noise at all. im in the u.s 120vlts, whats your outlet voltage?

The charger transformates 230VAC 50Hz to 5VDC 700mA here.
yeah i think that might make the difference. the charger is stepping down its voltage and hence more noise.
my friend i don't have this noise .
and my phone is close to me i don't hear it any noise .
i have 220 volt
okay.... i guess that shoots my theory down.
its a small transformer.... from 100V~240V DC to 5V DC.... so it is reasonable to make some high frequency noise as in other transformer.... its just a matter of the build quality of that small sucker
Yesterday I left my house with around 75% battery left to drive 40 minutes or so using the Google Nav app. I also had it charging using the included data cable and a usb conversion plugin.
I was also listening to Pandora as it was navigating with the screen on low brightness. However, when I got to my destination, the battery was at around 45%. I know the converter piece isn't broke as my ipod charges fairly quickly via usb when plugged into that same piece.
Is the data cable that's included really that bad at providing enough power to run the phone, as well as a mild charging?

Car vs Plug
Your car charger may be outputting at .5 Amp rather than 1 Amp; models exist for both. I do not pretend to know if .5 puts out more or less than GPS+Pandora; but your mileage may vary if you changed over to a 1.
I had a very similar issue this weekend. My problem was with overheating.
I left with my battery at about 60%, setup the GPS for travel. After about 20 minutes i noticed the charging light start flashing orange and green, and i noticed my battery was draining pretty quickly. The end result was that the battery was over heating (very hot to touch) and wouldn't charge because it was too hot, i had to remove the phone from the dock and put it in front of the air conditioner before it would continue to charge. This resulted in me holding the phone in front of the AC for about 2 hours because it could only last about 10-20 minutes before it would over heat again.
The dock is basically useless because the phone over heats, i have no idea if this would work differently if you start at 100%, but with anything lower it definitely fights to charge the battery and power GPS usage causing over heating.
Incase it matters i am using the Motorola P513 Car Charger (http://j.mp/cuOqWH) and the official car dock for the Incredible from Verizon.
That's definitely interesting. I wonder why they released something with that obvious of a fault. Major heat can't be good on the life of the battery.

I had problem with charging while using GPS and listening to Slacker but that was with this cheap charger I had. Once I used a higher quality charger (dont remember amps) it was able to charge and use GPS and Slacker at the same time no problems. It gets to about 115 degrees though. Battery says 140 is too hot so I figure its ok. If it fries....sending back under warranty.
It's definitely important to charge at 1 amp and not .5 or .75. I fried my battery to the point where it wouldn't hold a charge. Its worth the money for the right charger.

When you guys have the phone in the dock with the gps on are you leaving the screen on as well? If so that could be a big killer of the battery expecially if you have your brightness set way up.
I just got back from a long road trip (22 hours each way) and noticed the phone would get warm if i had the screen on so I could see the map but if I shut the screen off it would stay pretty cool while charging. It will still talk and let you know when you need to turn even if your screen is off. Maybe something for you to try?
Just throwing this out there because of the overheating issues but Proclip will be offering the Incredible package soon. Not only can it be positioned right in front of the A/C but it will come with a charging cable that can be ran to a 12v(?) source cable such as an after market stereo's power cable.
Sounds like, for me, I will be able to get a solid stable charge and have it in front of the A/C for cooling if I get that problem.
Again, just throwing out what I'm planning. I emailed proclip and they said early June for a release date!

Agreed. 9 times out of 10 when using a charger not meant for your device specifically, the charger has the wrong voltage and/or amperage or it doesn't communicate that the battery is full properly.
The wrong charger will either not work at all right away (best case), kill the battery slowly by overcharging it, or cause some immediate overheating issues through overcharging or improper charging (worst case).
tl;dr: buy your chargers from reputable places, specifically for your device! It's worth it!
I am still holding out hope that they will release the same type of car dock that nexus one has. That thing was almost perfect as far as car docks go. At least imo.

I drove from Mississippi to Florida and never had an issue. In fact, I listened to Pandora without a single interruption the entire way. Thats just awesome that Verizon's network had a data connection through rural parts of Mississippi and Alabama. Most of my trip was off the interstate.
FYI, I was using the rocket fish charger from Best Buy. It didn't have a proper dock, so my phone set in a cup holder. It never over heated but was slightly warm to the touch.

gummehbear, I have the same car charger and same problem as you. I tried looking online to see how many amps that charger puts out but I can't tell. So our phone needs a one amp charger?

sounds like what ever amperage it is, isn't enough. I have a verizon car charger in one car and one I bought at Radio Shack in the other and they both charge while phone is in use fine
As much as i would like to say its just the charger, i do believe it has something to do with the device trying to charge itself.
Yesterday I used the same setup as i did when i had the overheating issue, but this time i didnt have an issue. The difference was that the phone was at about 94% compared to the previous when it was at about 65%.
Yesterday the phone charged up to 100% before the overheating could become a problem.
I will continue to analyse it the more i use it, i am trying to figure out exactly what the factors are. So far from my experience i believe that if your device is charged up enough, you won't encounter this problem. It seems to be the charging event in conjunction with the GPS drain causing the battery to overheat.
I had the same issues on a trip to the Bay Area, up Highway 1 yesterday. The phone actually came up with a warning message that the charger I was using wasn't able to supply an adequate charge + power for GPS.
I purchased the Official car charger directly from Verizon and I have come across this issue. So the problem is within the phone, not the charger.
Sunlight: heat.
Using the device: Heat
Charging the device: heat
Is it hard to understand why its overheating?
Situation: Nexus 10 connected via the enclosed charger (micro USB). Headsets connected to the jack, which happens to be right next to it.
The quantity of buzzing makes it impossible to listen to anything for more than a few minutes.
I tried switching earphones but the buzzing was present with all of them. No buzzing when the charger is disconnected, but I need to be able to recharge the tablet AND listen to podcasts in the evening at the same time.
Do I have a bad tablet (so I should seek an exchange) or is this a design flaw and everyone is having this issue (so I should return the tablet)?

Sounds like noise in your electrical outlet is responsible. Do you have a computer, lamp, refridgerator, etc. plugged in on the same switch that may be dumping noise into the line? You can test this by plugging it in on another part of the house and seeing if the noise changes. I'm betting you may want to invest in a good power conditioner/surge protector.

Thanks, I will have to try that tonight. The buzzing noise was correlated with what was going on on the tablet (i.e. more when using it, less when just listening) and there's only a Galaxy Nexus and a clock radio in the outlet, so I didn't think of it.
I have the issue too.
For my part it's only when the battery is charged over approxymatively 80%.
At lower rates, no problems.

Same here, last night I got a horrible noise on my headphones while charging (noise related to what I did on the tablet) with the battery close to fully charged.
Today, same situation but the battery is at 37%. Perfectly clear sound.
Just wondering if this might have anything to do with the slower charging rate used by these devices when the battery is above certain threshold to lenghten battery life?
Hello everyone
I'm having a bit of an issue that's waking me up in the middle of the night, regarding my LG G2 charger.
When my phone is charging and ONLY AFTER it reaches 100%, the actual charger will start emitting a humming/buzzing/high pitch sound that is very very annoying and a bit loud as well. I believe this is happenning when it is making it's maintenance charge in order to keep the battery at 100%.
Does your LG G2 charger produce the same issue or do I actually have a defective charger ?
Thank you all
regards,
Nelson
You probably have a "defective" charging unit. That's likely an inductor coil in the charger that has a loose coil that is vibrating. It's not uncommon, it's how inductors work. Usually there is glue or such to keep it from rattling, but sometimes QA messes up, or things come loose during use. I wouldn't worry about it unless things become excessively hot. If it's annoying I would suggest getting a new adapter. My Qi charger adapter makes a similar humming/vibrating noise, but it's rather faint.

Hello and thank you for the reply my friend.
The thing is, it's not the heat that's bothering me because it actually doesn't heat that much!
The only problem for me, is the actual noise it makes when it is sending the maintenance charge after the battery levels reach 100%. It's a high frequency pitch, so high that it wakes me during my sleep lol
thank you for your feedback though.
It's a loosely soldered capacitor. If you still can, exchange the charger or get a new one.
