Buzzing AC / wall charger / adapter

Anyone else dealing with this? It was so loud when I went to sleep last night I had to get back up and hunt the room to find the source.
It's the wall charger. It buzzes when plugged into the wall, with or without the USB cable attached, but only without the phone ALSO attached and charging.
I come from a Nexus S and Galaxy Nexus and neither of those had this issue (nor any other wall charger for the myriad of electronic devices I've owned).
I'm not gonna reach around under the desk to unplug the adapter from the wall each time I'm done using it with the phone.
My usage scenario is probably really common in that I leave it and the USB cable plugged in, with the phone end of hte USB sitting on my desk. Plug the phone in to charge, otherwise phone is elsewhere. So, more often than not there is no phone plugged in, and it's thus buzzing.
Of course, Google can't or won't just send a replacement charger - they want to do a complete warranty return of the phone and everything. Such a major hassle for a small simple piece.
Does anyone know if the LG Optimus G has the same charger? I'm tempted to go to some local cell shop and try some other of the same charger to see if the problem is beyond my particular unit.

Happens to me too. As long as it charges I'm going to keep using it. If it goes I have a couple backups. I wouldn't return the phone though. Just pick up an after market charger and you should be fine.

Having the same issue, really annoying. There seem to be many faulty units...
But I fear they won't just replace them for free, because they are working well, just with this annoying noise. :S

IMO its just a charger. My phone is fine so if I have to use another I will. Walmart has some for like 10 or 12 bucks. But your right, charger shouldnt be faulty with that annoying buzzing sound.

Mine does the same and its only when the phone is unplugged from it. It takes a little while to build up the buzz. Its like they used a low budget capacitor or something. Who knows..

Same here, doesn't do it when the phone is plugged in so I don't really care. You can only hear it if you are right beside it.

Have the exact same issue with my Galaxy Nexus and Nexus 4 charger...

This is the 3rd nexus I've had due to various faulty reasons and all 3 have had the buzzing in the earpiece and an even louder annoying as hell buzz in the wall charger. The last 2 also have the rattle while the first didn't but I don't care anymore I still love this phone and will live with the annoyance. I don't really hear the earpiece buzzing unless it's silent in the room

Mine doesn't buzz, but squeals at a high pitch (15+KHz). It's not a constant tone, but warbles up and down in volume making it almost impossible to ignore. Swapped to the charger for an old iPhone one I had lying around. It only has a 1A rather than a 1.2A output, so it'll charge a little slower, but it's worth it to avoid the racket.

I am having the same issue is yours charging really slow some time I left mine overnight and it was around 25 :banghead:

Having the same issue as well with my charger. Very annoying. After I unplug it from the wall it still buzzes for about 30 seconds then stops.

Buzzing is just a capacitor inside charger.
When there is nothing connected capacitor is getting current, but with phone connected current goes to your phone.
Buzzing last even after charger unplugged because capacitor is like a temporary storage and gets discharged in few seconds.
Capacitors prevent power fluctuations, and help prevent ditect damage to device if there are fluctuations in power supply board.
Nothing to worry about it, many industries use capacitors to maintain their power factor (voltage/current) ratio.

Yep, experiencing this problem too. Personally, it's really annoying for me, the charger is just 30-40 cm away from my head when I'm sleeping.
I wonder if I could use another charger, I've one with OUTPUT of 5.0V and 700mA, that should be fine right?

Who's worried about it? It's annoying and obnoxious.
Person above: any USB charger is fine. The higher the possible current, the faster the charge (to a point, the phone will only ask up to a certain amount)

Yeh I have this on my UK charger.
It is recommended to unplug/switch off at the wall anyhow as a charger will be using power even when not connected to the phone.

An ancient 'wall-wart' transformer PSU maybe, but a modern switch-mode PSU will be using a handful of milli-Watts at most when idle. Not really worth unplugging to save power: home electricity is measured in units of 1kWh; at 10mW, you'd have to leave the charger plugged in for over 11 years to use 1 unit.

mine buzzes very loud too. both my nexus s chargers also buzz but not as loud as the LG one.

All the phone chargers iv used have got pretty warm when I've accidentally left them plugged in with no phone. They are using power so it just seems common sense to unplug (or switch off at the wall, which is what I do in the uk).
I'm not sure where you got your numbers but a quick Google found these :
the Lawrence Berkeley National Laboratory, who measured several devices in each category, a cell-phone charger draws an average of 3.68 watts when the phone is on and charging; 2.24 watts when it is on and charged; and 0.26 watts when it is just hanging out in the socket

I have the same problem with my Nexus 4 charger. Decided to use my Sony Ericsson Xperia charger instead.

This problem still annoys the hell out of me because my charger is next to my bed and I can hear it all night if I don't have my phone plugged in.

Would have been even better with wireless charging

This phone would have been more perfect with wireless charging built in, anyone agree?

It doesn't have wireless charging but the dock that comes free with the phone in some areas doesn't need to plug into the phone and must do it wirelessly or via pins just beneath the backing I suppose

There are 2 contacts on the left hand side of the phone which get used with the dock. They are power only - not USB or HDMI. There is *no* wireless charging in this phone.

Nokias wireless charger works with all phones that have NFC, looks like i will be buying that then!

From what I've seen wireless charging is presently a bit dodgy anyway, perhaps Sony are just waiting for the tech to settle down a bit before introducing it. I don't think I'll be going for wireless charging with my N4 any time soon.

I don't think so. It has NFC so that you can launch a task when you put your phone to charge, but it's still based on the Qi wireless charging spec which means the phone has to be compatible too.

just looked in to it, sorry your right, i had read somewere without looking it up. My bad!

@OP: Why would you want wireless charging in the first place? It's just a gimmick it might be nice to have but, when you don't have it you won't miss it either way.
Same with 3d also a gimmick, we can live perfectly without 3d movies etc. Even though 3d movies can be quite nice to see.

wireless charging is not comfortable for daily uses

I had a Droid DNA and hated the wireless charging. For one you have to pay upwards of $25-$50 for a wireless charging pad, charging takes several times longer, the phone/battery get hot while using it, which will probably lead to shortened battery life, and it's not like you can use your phone while wireless charging since if it moves more than a few millimeters off the pad it stops, versus wired where you are limited only to the length of the wire.

Isnt wireless charging jsut putting the phone on a "dock"? Like my cordless phone? or the old nokia's where u had to put it on a charging dock? Ppl behave as those it is sending microwaves to your phone within a certain radius and the phone magically charges...and if it were like that I would be afraid of nuking my insides lol

Exactly my thought. It's wireless, but you have to put your phone on a mat... i really prefer putting my phone on a dock, and the one for Xperia Z is very good because there is no "port" that might go loose with time, just two metal pins that are touching the charger pins.

For those in doubt - here is the dock Sony will release to go with this phone - Not quite wireless charging but nearly. Having seen this it has convinced me to get the phone - the thought of fiddling with the port covers in the dark every night to conect the charger was putting me off (my gf goes to bed before me so I can't put the light on).

[Q] Hard freeze overnight

Hi,
My IncS has started playing up over the past week or so.
Every night now, when I get up in the morning I have to remove the battery from the phone and power it back up as it has totally frozen.
Another weird thing is the battery is normally really drained once I have it powered back up. Doesn't have any problems during the day at all, never freezes or anything but overnight when it is plugged in to charge,it dies.
I've tried replacing the battery (I had a spare) as it only happens when mains charging and, like I said, when it is turned back on the battery is substantially lower then when it was plugged in but that didn't help.
I tried totally wiping the phone and installing a new ROM (szeszo's lovely new cyanogen with his Tesco kernal) and it is still happening...
Anyone else experienced this? Any idea what's caused it? And finally, does anyone know a way I can do so kind of logs about what is going on?
Thanks...

I had the same issue too. Was USB connector related. Had to sent my device to htc repair

Try a different USB cable on the charger
Sent from my HTC Incredible S using xda app-developers app

Unfortunately it didn't turn out to be the USB port or cable. Thanks for the suggestions though.
It started freezing when it wasn't plugged in at all and it was doing my nut in...
Yesterday I bought a Note 2 and it gets delivered today. I know, it's huge and I'll probably end up selling it on when I get fed up of having to carry it round in a wheel barrow
It is such a damn shame to be putting the IncS to sleep at last. It's been a damn good phone for a long time (probably the longest I've ever used 1 phone for!). Somehow I can't imaging the Note being as well made as this was. The moment HTC do a Nexus phone I'll be selling whatever I have and buying up cos that will be awesome.
Anyway, guess I'll be off to the Note forums now.
Later guys, and thanks...

Charger pins broken.

Basically I want some advice from people on here.
I've broken my charger, the one that comes in the box. The plastic strip out of the port on the side has snapped off. (I use a 3 metre USB cable in it due to weird plug placement in my room, so the weight may have played a part)
What I have got is a HTC B270 charger from my One S I still have and a TomTom charger that can replace it with.
What I want to know is simple... Is there any pros or cons to using them when I can buy a replacement for a fiver off Amazon?
I'm being serious before anyone shoots me down, I know certain chargers charge faster than others and such.

No problem, but slower charging time. 1.5 vs 1.0 Ah.

[SOLVED] Desire C - no LED, screen lights up (slightly), but no boot

OK, maybe someone out there can help me - I've been googling and reading XDA for answers, but not really found anything.
My GF's daughter has a Desire C, and dropped it off this morning reporting the following;
It started playing music without anyone doing anything this morning, and the screen wouldn't turn on. The only way they could get it to stop was pulling the battery.
Replaced the battery and the phone wouldn't start.
I read up a bit and left the phone on charge (no LEDs showing) for 2 1/2 hours. Came back, still couldn't boot.
I took the mains charger out and plugged it into my PC USB and tried volume down + power - still no boot, BUT, the screen did lighten slightly...
So, I WAS thinking the phone was bricked, then, as I was typing this and retried the plug into PC bit - the phone has booted
I was going to delete the post, but decided it may be of use to someone, so I added 'solved' to the title.
In a nutshell: if you have this issue, be patient - it might not be the end of the world (or phone!)

Any idea what the problem was?

I'm thinking the battery is getting to the end of it's life - it's gone again, so I've left it on AC charge until a friend gets around with another Desire C so I can check with his battery.

Hmm... How old was the battery?
Sent from my HTC Desire C using XDA Premium 4 mobile app

Now it seems to be REALLY fixed...
Battery age? no idea, it was a secondhand phone.
Look at the picture though - I've circled the relevant area.
It seems the battery cover has a 'tag' which fits into this and makes contact with a thin metal strip which enable the power button - well, in my case, pushing a plastic stick in there made the power button go on and off anyway.
Looking at the rear cover, the tag seems a little worn, so I trimmed that off with a sharp knife (without cutting myself either!), and trimmed a small piece of old credit card folded over to fit the hole.
And it works - power on, power off.
The battery is reporting to be full so no LED still (does the LED come on when it has full power? I've not noticed), I'll drain it a bit and try plugging it in to see if the LED comes on.
When my pal gets around with the other Desire C, I'll try his rear cover in this phone and see if it was just down to a small worn piece of plastic...
Been an interesting day for me - just hope this 'adventure' will be of help to someone else - I was thinking mainboard/battery problem and it turned out to be a 2.5mm x 1mm piece of plastic...

Just checked mine and you are right. Good to know. Thanks.

As far as I've seen there's no LED implementation, seeing as the screen never goes off whilst on charge if powered up or not
