Charger Whistles?...

I just bought this phone from wind (called optimus 2x but is LG-p999) and when i plug in the my phone to the wall charger, it does this wierd whistling noise that is kinda annoying. When i charged it with the computer there isnt that noise so i know its the wall charger. Does this happen to anyone else and is there anyway to fix it?

lol no, somethingg has got to be wrong

The one thing i didnt want to hear I guess i should return it.
Edit: Also, is charging faster with the wall charger or is it the same thing with PC?

Wall charger is faster, 1000mah as opposed to 500mah.
Definitely faulty though. Any old USB charger will do to tide you over.

I don't have any usb chargers, just the phone's. Also do you guys think it could damage the phone in anyway?

I wouldn't have thought so, noisy transformers aren't exactly uncommon, but they are annoying.

i wouldnt worry mine does this with no ill issues. A few of my chargers over the years have also done it. Some people are just more suseptable to noise than others lol.

My charger is whistling as well. But I wouldn't be too worried about it...

mine whistles when its almost full. like 90%

It's a Characteristic of Switched Mode power supplies
All of my later Nokia chargers did it, And My HTC
It can be annoying but nothing to worry about

Mine makes a weird clicking noise.. When it's been charging for a while (the charger, not the phone), it even continues after I pull it out of the wall socket!

the lg charger is ****, get an iphone charger from ebay or dealextreme, at least thats what i did

mine whilsted, but when i hit it few times, now it doesent, it also seems it charging better now...i'm not kidding...

Keep an eye on it though. Usually the difference between a piece of equipment that is exhibiting high performance and one that is about to explode, is slight.

WARNING!

I got stupid and bought an after-market power adapter for my Nexus from -- where else? -- eBay. I've bought a bunch of stuff from these guys before and everything worked as advertised. http://tinyw.in/d5b9 Not so with this!! In fact, I'm lucky to have anything left of a tablet. I plugged it in to "top it off" and it read 87% I came back three hours later to an N7 that was so hot I could barely hold it and the meter said 17%!!! I'm hoping it hasn't damaged something permanently. So far, so good. We'll see after an overnight charge on the OEM charger.
Word to the wise -- don't cheap out on this stuff. It could cost you the tablet!

Sure you didn't leave a game running or something?

Always good advice, in your case though it might be possible that you didn't have a very good connection from the micro usb plug to the N7. Measure the voltage output of the charger and if it's ok it's worth trying again but not leaving the device unattended.

Possible, but highly unlikely.

Not a chance. This thing is going back for a refund. I think I got off extremely lucky and I'm not tempting luck.

I've had about the same thing happen with the stock wall charger.

Don't you just love ambigous thread titles like this? Catchy eh? You caught me clicking this one just out of my curiosity.
Thanks for the heads up though!

Hardware Defect with USB communication and charging

I reciveved my phone yesterday and after playing with it for a few hours I charged it last night and noticed it became hot to the touch in a few minutes of being plugged in. Like burn your hand hot and there was a bit of a hot plastic smell coming off it. I unplugged it let it rest. Today I have no usb access to it. No adb, no fastboot. Lsusb shows no devices etc.

Xplodwild tweeted out the other day about issue with USB charging similar to this. Does the same happen when AC charging?

Is this problem similar to this guy?
Watch out for overheating!

seems to be a similar issue - it was very hot on the back side just below the camera especially I'm just afraid it got too hot and something was damaged.
This explains why google was pushing their bumpers instead of a full case I can't imagine a case would be good for this things thermal characteristics.
This happened while charging via ac when charging via usb it just seems to hold steady at whatever level the battery was.

Just out of interest, what surface did you leave it on all night?

I left it on a wooden desk for 5 to 10 minutes it didn't take long

It is no longer charging. I can't get it back to stock to rma I'm not happy :crying:

Woah, all other nexus 4 problems aside, this one is quite serious.
Just imagine what would have happened if you'd have left it on a easily flammable surface and wouldn't have noticed the heat. Worst case scenario might have been a fire or something like that.
If this really is a common problem (I've already seen at least two people reporting similar issues), we might see a big recall campaign quite soon.
I guess you don't really want the LiPo battery in your phone burst like this
http://www.youtube.com/watch?v=z3o_2mwRPdw&feature=youtube_gdata_player
Maybe Google should start to sell these bags instead of the bumper

Where you using the provided USB-AC adapter?
I know that my friends GS2 and GS3 got really hot when using my playbook wall charger (rated at 5v ~1.8A) :S

Heard of similiar issues with nexus 7, but the one I'm aware of is still charging.

I haven't experienced this issue yet?

I contacted google play they were quite happy to send me a replacement. Aparently they held back stock in case of a need for returns. HOWEVER they tried to charge an authorization hold on my account in the ammount of $350 I DONT HAVE ANY DAMNED MONEY I JUST SPENT IT on their ****! The only other option they said was to return it for a refund and wait a large number of weeks for orders to open up again or send it directly to LG for the same treatment ?!? I'm PISSED. The guy said that this was not the first case he'd heard of like mine didn't even ask any questions except for the serial number - I'd expect that there are going to be quite a few issues like this.

Yeah, sounds like my problem. Was your microUSB port also loose/creaky like mine? I got Google to RMA me a new one. It's a shame, I love this phone and this one has no give on the screen whatsoever and no rattle. The port though and the screen flicker are another story...

I don't have screen flicker yet and the port isn't lose I'm thinking somebody cut some corners on the voltage regulation

Damn, I guess this is sorta good news for all the folks (myself included) whose banks dropped the authorization, haven't had Google recharge us, and have the phone in hand.

[answered]Not charging via pogo pins

My dock has been charging my phone perfectly for weeks, the other day I came in and plopped the phone on the dock and nothing.
I checked the pogo pins (of the dock) with a multimeter, they are working. I've tried different power sources for the dock as well (wall adapter, pc, other cables).
I've checked to make sure the pins are making contact with the phone, good solid contact.
I haven't changed anything on the phone recently, any suggestions?
The phone charges fine through USB.
[ANSWERED]
since i apparently posted this on the apple forums instead of xda, all the replies were "shoulda bought apple products"
so anyone having this problem, i solved it by reinstalling a nand backup. apparently it was a software issue. hopefully this saves you from the apple fanboys.

do you have original sony cradle? i had chinese replica and it did not work all times.

No, I was too impatient for it and got the goosewhite dock, besides I like the looks of it better tbh. The dock is putting out power, I don't get why it's not charging. its not a complex system at all.

Get the Sony one if you don't want the same issue occurring.
Sent from my C6603 using xda premium

why would changing the dock have anything to do with the problem? when voltage is applied to the pogo pins, the phone does not charge. how would changing the dock i use make a difference in that at all?
i would understand if the pogo pins were putting out less power or no power, but they put in exactly the amount of power going into the dock, they make good solid contact, i've check continuity and its making a solid connection...

Then take the dock apart and see if anything got loose

Because the one you've bought is rubbish!
I brought this as an alternative to the Sony DK26 because I was sick of opening the flap everytime I wanted to charge my phone. It does fit the Xperia Z and looks nice enough. It also activates the dock mode and the Xperia's smart connect function. This is why I gave it 1 star. HOWEVER, it outputs at 500mA as opposed to the 1800mA delivered by the Sony dock. This means it charges your phone incredibly slowly. I had my phone on the dock charging for 11 Hours and it managed to deliver a battery charge of just 51% which is ridiculous compared to the Sony charger which delivers a 100% charge in 2 hours.

I do not get why would anyone go for something cheaper and unreliable. Its like those iPhone users buying cheap non original cables to charge their iPhones, ended up causing the phone to blow up or messed up and blames it on Apple.
and yes you are the owner of the phone and you have the right to buy whatever 3rd party equipment for your phone, but dont expect it to work 100%.
Doesnt make sense if you ask me sir.
It is really hard to determine the main cause of this matter. It could be your phone: hardware or software (i doubt it is this one), or the 3rd party dock.
You tell me which one to throw and buy a new one.

Already told you why I bought it. There's nothing but stupidity in that review as docks do not put out power, they transfer it, the power supply puts out power. As for the amperage, it puts out what you put in. it will do [email protected] if you are stupid enough to put that through it... Assuming the wires don't burn. if you are going to base your assumptions on a review, at least choose one from someone knowledgeable. also, my dock never took 11 hours to charge, not that i ever bothered timing it but it sure as hell wasnt more than 4 hours (and thats giving an a good bit of a safety margin), i'd guess 2 hours 0-100 if i had to.
What I'm telling you is that the phone is not accepting the charge, not that the dock is messed up but the phone. And I wanted to know if anyone had similar issues or suggestions.
I'm glad you have insight on the matter and an opinion, however you are not trying to answer the question. I've already informed you the dock is intact and making a connection. I've checked the voltage of the xperia official charger at the cable at its end: 4v dc, the dock when hooked to that charger is 4v dc tested at the pins. I can put a larger amount through it, and any number of amps. A pogo dock is a very simple device, official or otherwise, the difference is mainly in price and design. The diy thread is a perfect example of that.
@LitoNi
I took it apart, nothing is loose. thanks

It's been answered, you've not bought an official product, that's the problem! Buy cheap unofficial batteries, expect issues, buy cheap replica SD Cards, expect issues, buy cheap unofficial chargers, expect issues, and looks like you can cheap docs to that list too.

XperienceD, please continue answering me with your infinite wisdom you learned from the internet. obviously you know everything about electronics.
btw fixed it, reinstalled my nand backup. software problem ftl.
didnt know this was an apple forum.

Having issues suddenly with my droid turbo not responding after going dead

So I was using my phone and was running low on battery power. My ended up dying at like 5% as usual with my droid turbo. I was with my friend in his girlfriends car and plugged it into her cheap charger she picked up at a gas station or something. My phone registered the charger and then began the battery symbol like usual although it never got to the battery percentage, it just stayed as a gray battery symbol with the lightning bolt. After a while the phone screen went black and wouldn't respond to anything and figured that the charger just made the phone go dead and that I could plug it into a Verizon charger to make it work again. When I got home I plugged it in and nothing, no response at all not even the green light at the top of the phone. I plugged it into my computer and it shows up on device manager as QHSUSB_BULK. Now to be clear my phone was never rooted or had anything done to it. The phone was completely stock. I need help frantically because I need to get some media off of the phone if at all possible, whatever the cost. Not sure if just letting it charge for a while will help or not. Thanks for the help in advance.

If you plug it into your home charger it should turn on at least and show the battery symbol when charging and it should go up if you haven't tried it already. If it doesn't, sounds like some kind of charging issue.

The phone doesnt respond at all to any commands. The green light doesn't even pop up as if thebphone was clear dead. Took it to Verizon they thought the battery might be fried which I guess would keep the phone from turning on.

That is entirely possible. When I buy after market chargers, I generally only buy anker stuff. I've never had a problem with their stuff. Get what you pay for. Not that you bought that but yeah.

Yeah I definitely learned a lesson. Is there any way I can get the data off of it though? Would Motorola recover the data for me or is there some way? The data should all still be there considering there were no deletion processes. Of course maybe im wrong but I just hope I can get everything recovered.

It's possible if it will connect to your computer and you can read it but otherwise I'm not sure

Assuming the charging port is damaged you could try a wireless charger.

Well like I said the computer can read it, but thats all it can do. It recognizes it as being plugged in but cant do anything else.

If you try a Qi wireless charger, that would give it the chance to actually charge. Maybe some circuitry in the USB port is damaged and it's not receiving a charge. You actually have the phone, so you know better. But wouldn't hurt to go to a store and try putting it on a Qi charger for a few minutes as a test. When my phone is OFF and I put it on a Qi charger, it actually turns it on, boots the phone.

That is definitely a thing to try. If your computer can read it then you can easily save the files off the phone.

I'll have to give that QI a try. People st Verizon probably didn't even think of that.
How would I go about getting the data off of it though? The phone doesnt show up on computer just shows up in device manager under the code I wrote in the first post.

One step at a time. If it will charge normally with Qi and boot, then it once booted it might show up as device on PC.

I tried the QI charger and it did not work. Thr light on the Verizon pad flashed red. Thr battery has got to be fried. So im not exactly sure what to do next.

Well, you can always get a new one through insurance or through swappa. I get that it's the stuff you want to save though. Might not be able to if your computer can't see it as a SD card unfortunately.

Well the way I look at it there's always other phones but not memories. So if worse comes to worse I'll just tear the phone apart and find the internal storage.

So there's no way you guys can think of to get this data off? I could use all the help I can get

Even if you tore yours apart and found the memory chip, it's soldered onto the board. I know because I've opened my turbo to do repairs and it's not hard but not easy. Maybe, just maybe, if you had the sophisticated equipment you could apply the proper voltage to be able to read the card, assuming you could find the + and - pins on it and then also the transmit pins on it and solder yourself a usb cable to direct connect to it to the computer, that might work but would be extremely complicated. I'm a professional electronics technician and I test, build, and repair boards but not phones. I do surface mount work though. Anyways, got off topic. So unless you got that going for you, I don't see it happening.
One last thought, do you have Motorola drivers installed on your PC? Could help. Don't know.

There are youtube guides out there on how to replace the battery in this phone. It's not easy, but it's probably easier than finding the storage chip and figuring out a way to build a new physical interface to access it. New battery = resurrected phone = get your data back. Maybe.
https://youtu.be/VHFkTgjWzOo

Yeah that's also probably a lot easier than all that. The battery isn't too hard to replace. I totally over thought that.
