Hi all,
Several days ago I got a brand new LG Optimus 4x HD. Last night I plugged the phone to charge and went to sleep. This morning when I unplugged the phone, a weird buzzing sound was coming from the charger. The phone was charged 100% and seems to be fine. Since the LG charger looks a bit cheap compared to other chargers I have seen (made in china by Sunlin T_T). I have charged the phone several times by now, but noticed the sound just today, I dont know if it was there before. I decided to see if the charger from my previous phone (Xperia mini, used for over a year and still working fine) will make the same sound and it actually does! Its alot quieter and I could not hear it until I put the charger to my ear, but its there. Also with both charges the sound continues for a while after they have been unplugged from the wall socket.
Should I be worried ?Note that the warranty of my phone does NOT cover the charger itself, so I cant replace it. If needed I will change the charger with a Duracell or Energizer charger, since here its next to impossible to find separate original phone charger.

the sound is normal. it happens in almost every AC to DC step down transformers. The sound should come on a short while after you unplug the phone, and slowly go away when the charger is unplugged. It will also stop when you plug in your phone.
you can do a little experiment here. When you hears the buzzing sound, switch off the charger or unplug it. Then without any power, plug in your phone FAST. You will see your phone is getting charged for abit, then it stops together with the buzzing sound.
anyway you shouldn't leave your charger switched on when its not charging, its a waste.

Thank you for the info. Now I noticed that the charges makes buzzing sound only when the phone is 100% charged or when the phone is unplugged from the charger but the charger is still plugged to the wall socket.

hi, new member here.
bought my tilt on 10/4/07. has been flawless since that time.
used the nav quite a bit during a road trip, used a cig lighter usb charger.
got home and my battery was at roughly 40%.
put it on the charger at night went to sleep. in morning disconnected it at 8 am. shortly after i arrived at work i got the critical battery low chime. checked and it had like 7% battery life.
figured i didnt plug it in right, or it got knocked loose some how and didnt get charged.
put it in flight mode to minimize battery usage. left work at 2 30 pm (4% battery life) and put it on the car charger. got home and put it on the HTC supplied wall charger. light turned amber, so i assumed it was charging.
checked an hour later and turned phone on, it said 0%, and immediately died. left it on the charger for a few hours and the light was still amber, turned it back on and again 0% and phone immediately died and did a soft reset on its own. i turned the phone off and left it on the ac charger, took out the sim card and put it in an old blackberry to use while the battery was charging.
its been on the ac wall charger for the last several hours, i checked and the phone is totally dead, cannot turn it on, and the LED at the top is now RED.
what is the problem here? why wont this thing charge?
thanks in advance, i have alot of critical info on this device and any help would be greatly appreciated.
i cannot hard reset because i cannot turn the flippign thing on....
Does it charge when you connect it to your computer? If it does, then your charger is toast. If not, then it's probably the phone itself.
I'd try a different charger first. If that makes no difference then a different battery. If that still does not make any difference then time to exchange it.

connected to either the computer or the wall charger, the LED thats normally amber when charging, and green when charged, remains red.
I had something very similar happen to my wizard.
And as weird as it sounds, the only fix was to charge the battery in a friends wizard on his charger. I'd check the battery if possible.
Could be the battery. Know any place or anyone that will let you try a charged battery? If not, you might have to go in to an AT&T store.
i think i got it working. did some reading/browsing...
took a usb wire and cut the mini usb head off. dissected it and found the the red and black charging wires. took out the battery and held the leads to teh battery while the other end was plugged into a USB/AC adapter wall charger from a old blackberry. after manually charging the battery for several minutes, i put the battery back in the phone and the phone started up. now it seems to be charging off the wall charger and the led is now amber from red.
thanks for all your help/suggestions.
well it worked briefly. the amber light has gone back to red and it seems that the battery is not charging.
dont know what happened to my perfectly functioning phone.

Repeat this proceedure but this time do not turn the phone on, just plug it in to the wall charger once you have zapped the battery again.
Turning your phone on probably just caused the already recovering battery to die whiles it is trying to take on a charge.
It is mentioned quite a lot on the boards that Li-Ion Batteries do not like being over disscharged and there is usually a little protection circuit in the battery to provent complete disscharging although this circuit may be on board the phone. Completely disscharging a Li-Ion cell will kill it stone dead and it will need replacing.
When you took the battery out and so called jump started it with your flying leads, this possibly reset the little protection circuit in the battery so it can now take on a charge. I feel that once you turned on the phone, this was to much for the already depleted cell to take and possibly re-tripped its inbuilt circuit.
If you do manage to recover you cell, in future it is good practice not to let the battery go below about 25%. Li-ion cells are generally happy being top off regularly.
I hope this helps buddy
Do let us know!
Cheers

thanks, that was very helpful.
ive tried defibrillating this battery out of the dead several more times to no avail.
ill try it one more time when i get home from work, if its a no go i will go to teh att core store. the phone is 6 weeks old, dont know what they can do for me if the battery is toast...
That Sucks! I hope they'll give you a new battery.

I had exactly the same problem with my battery. It came on though after a day. Although the battery life after this happened went down to 10hrs max on standby. I sent the phone back and got a new one and now all is fine.
This is a problem that affects almost all makes of phone. There are three (main) causes of the problem:
1.
The battery charge drops too low to allow the charging circuit to recognise a battery is even in place (red no charge light stays lit)
possible solution:
http://forum.xda-developers.com/show...22&postcount=6
(in the end very similar in the end to the USB wire used in post above)
2.
A faulty battery (but if you can charge it using a cut usb cable or using a couple of AA batteries this may not be a faulty battery.
3.
A faulty charger OR a charger not delivering 5v at 1000mA as the OEM one does. Many chargers that are used for other phones or generic chargers only deliver 500mA. This is not enough when your battery drops very low. (these chargers are OK for occasional use but I do not advise using them regularly particularly if the no-charge syndrome has shown itself)
4.
A faulty USB connection on the phone. I have now seen a couple of reports where the fine wire connections in the phones USB port have become bent out of place.
Number 4 above is at least possible for the OP as it seems the battery will charge using a cut USB cable but not when either the PC USB cable or mains charger is connected. A USB port on the phone with a a bent internal contact would explain what's happening.
A previous poster was able with a needle or similar to bend the contact back into place.

i had the same problem with my phone.
put it in the charger overnight and woke up in the morning and couldnt turn on the phone with blinking red light. I don't know if my battery was over-drained though. I went to AT&T and was playing around with their charger and new battery and somehow the so-called dead battery started working again. They changed the SIM card on my phone there and then i haven't been able to use the phone since. I've changed the network to GSM instead of Auto setting under Phone Options which allows us to make calls; but now I can't connect to 3G network.
Charging thru mini usb
My phone started to exhibit similar problems...plugged in but no charging of the battery. I finally realized that my mini usb connection on the phone has been compromised (bent, distorted=not functioning properly) Now I have to prop the mini usb connection up at a slight angle to engage the charge. I think the plastic/metallic connector on the phone is somewhat fragile ...I had similar issues with my hermes.
called customer support.
they are sending me a new phone and battery.
how do i know its not a refurbished one? any clues?
before u send out your defect phone, have u check if your phone's mini-USB connector has bent or misaligned pins?
yeah all the connectors visually are fine.
ok i bought a new battery because my last battery drained and wouldnt charge back up. and now wen i charge my phone it just drains as if it wasnt plugged into the wall charger.

I had a problem where the Tilt wouldn't charge until I deleted a waiting voicemail and a few unread emails. This was on a cooker ROM but check it out.
Hope that helps.
check the connector on the phone and see if it is broken I remember on my first two tilts it broke and I had to get new ones (warranty) and then the third ones broke but i used a small screwdriver and put the pieces together again.

Don't throw away your old battery because it's probably not to blame and you can then have a spare. How does it go if you attempt to charge via a USB cable connected to the PC? Will it still connect via Activesync over USB? Do you still get the orange light on the left of the phones earpiece when you're attempting to charge it? These are some steps that'll help to narrow down whats going on - let us know.
Had this problem using on of the original M2d (roms).
Now im running hyper dragon w/ m2d cab and all is well. Ive also experience this from a bent pin. (dont drink coffee for 1 day prior to attempting mini-usb surgery!)
umm.. when connected to the charger the orange light is on i bought a charger on ebay and it charges the batteries up so now i have two batteries using one as a spare when one is charging. the usb doesnt seem to be broken. a lil background i spilled water on it a lil while back but the phone works fine i have a feeling that that may have something to do with not being able to charge but why would the light switch over to orange then when i charge it. sorry if this seems really noooob
My Kaiser failed recently with not being able to charge. Most of the time it didn't charge but if you wiggled the connector around the charge light came on, then went off moments later as the connection/wire combo moved. I contacted Orange and they sent me a replacement. No problems since.
Most of the time my PDA goes into a charging cradle but when that fails I use the car charger/other mains lead.
As for being a Noob, we all have to start somewhere

My fix
Stuck my stylus in there by mistake and could only cvharge if i wrapped the cord around.
I recently bought a rechargable battery pack for my daughters wii, and it came with two usb cords (from target $26.99), and one day i plugged my tilt in and it charged no problem, been using this ever since (November to now).
Cnn.cn sells the usb part of the phone, Im just to afraid to solder the old one off and the new one on. Might try it one day!
I have the same problem currently. I plug in and the light comes on, but the battery does not charge. I'm waiting to borrow a friends battery so I can reflash to standard to send back to HTC!
I got my phone wet last week and I am having the exact same problem. I have a battery charger and 2 batteries so I am doing the same thing as you but it's getting a bit old.
I dont have a warrany so I'm hoping to find some good ideas here as to what (if anything) can be tried.
Update:
I decided to crack open the case tonight and take a look inside. Unfortunately I couldn't find any youtube video tutorials so I had to just go carefully and not force anything. I ended up only having to take apart the motherboard side (keyboard side). Once I had the phone completely apart, I taped a known good battery in and connected the charger. A physical inspection passed, no burns or shorts that I could see and no funny smells. After about 30 minutes of charge time, I unplugged the charger and the battery power had increased 10%. Sweet.
It turns out that the battery I had in the phone when it got wet may have been ruined though. That one will not charge even in a standalone battery charger. That's allot cheaper than the alternatives I was thinking about though. The Fuze was really calling my name today for a couple hours. Saving $500 though feels pretty good.
For some reason after a couple days of using the iphone wall plug to charge my phone, my phone will no longer charge any more.
When charging with the iphone wall plug it would take forever to charge and im wondering if this may have damaged the battery.
a couple of nights ago when i had my phone on the iphone charger over night I woke up to my phone still being on 20%, the same as when i plugged it in.
since then the battery has been acting very weird and i can't even get it to charge over 20%
right now the orange light does not even blink when i plug in my phone and i have not been able to turn it on since yesterday morning
i have the phone under warranty but i have viper rom running on my phone\\\\How can I get my phone back under warranty if it wont turn on?
Dont have a PC, just my macbook

I don't get it correctly.. did you also try some different connection cables? And with iPhone charger what do you exactly mean... can you send a photo?
If you send it in they'll most likely throw it away and give you a new phone if they are not able to turn it on. Replacing the battery costs way too much for them. But this information describes just a probability.. and that's useless..
He used the wall plug that came with his iPhone. Its also rated at 5V 1000mA output.
It should work just fine.
What i would reccomend is using a different data cable and wall plug. If you dont have one try to borrow one or go into a store.
Its possible that the data cable and / or the wall plug your using is bad.
Those are easy to rule out. If you do get different cable and wall plug and still have a problem then you have ruled out those and its your phone.
Till you do this it is a phone, cable, or wall plug issue.
Hey Guys,
So after the last AT&T update to my phone the phone started acting erratic and the bloatware was ridiculous. My phone was constantly loading apps, changing time zones, and making emergency calls.
Then last Friday the phone thought the earpiece was plugged in. So I couldn't use the phone.if I put a earphone jack in the volume went all the way down on the phone and different things went crazy.
I took the phone to AT&T service on Saturday. They said they needed to reflash the phone. So they reflashed the phone. And the earphone issue was gone.
But when I plugged the phone into my car charger the phone started discharging even though it showed it was plugged in.
At home and on my desk at the office I have a little charging deskstand for the S4 active. Sitting in the stand the phone discharged. But if I pulled the micro USB out of the stand and plugged it directly into the phone it charged.
Well after a couple of days the reflashed phone was dead. It was rebooting every 15 minutes, and kept losing Bluetooth devices that were attached to it.
So today I went back to AT&T service center and they gave me a new phone.
The new phone is functioning, but it continues to discharge in the desk stands or with the car charger. With the deskstand I know it's not the wall wart, because plugged in directly the same wall wart rapid charges the phone. And this is happening with 2 stands and 2 different wall warts.
And I find it hard to believe that at the exact moment this happened the charger in my car failed.
Does anyone have any idea what setting is hidden somewhere in the OS that might be causing this?
Thank You I really appreciate the help.

I've had my N6 for about two weeks now, and lately I've noticed it doesnt charge once I plug it in, I'll go to sleep and a few hours later its still at the same percentage, I check the battery stats page and it shows "Not Charging" I unplug it for a few seconds and the Charging icon sticks as like the phone thinks its still "charging". Another issue I've noticed just now today, it says itll take 4 hours to charge from 56%! Only way for me to fix these issues it is to restart the phone and itll work, mind you this issue only happens sometimes. Although I will say I plugged my LG G2 into the Turbo Charger, so IDK if that affects the charger in any way?
Does anyone else experience this? If this is something no one has I'm planning to swap the device out for another one.
Running SinLess ROM v1.0.3
what charger are you using for your n6? and where are you plugging into? wall or usb?

This may seem obvious but try a different cable. I had a cable that, when plugged in, my phone would say is charging but doesn't actually charge.
I've had my nexus 6 for a couple weeks now and the first time this happened I was using a wireless charge so I thought I didn't have it placed on the mat right. But it happened again last night whilst plugged into an AC charger. The AC charger is an LG charger from a previous Nexus. When I look at the battery graph it just flat lines for the whole time it was plugged in.

My turbo charger is doing the same thing the OP said. We have 2 6's and it also happened to my wife's the other day too. I thought it might have initially been a cable too so I changed that out and it happened to the second charging cable last night as well.
Just experienced this
I use the turbo charger also and just experienced this. I was at 25 % after playing injustice (which just murders this battery) and plugged in the USB and I looked back 5 minutes later at I was at 22 %. So I killed Injustice and waited about 5 minutes more and I was at 19%. I had to reboot to get charging and after 5 minutes of charging I was at 29% so it is weird stuff.
I've been noticing this as well, but my charger is an aftermarket charger by Tenergy (Amazon link), and I'm using an aftermarket cable. Missed my alarm this morning because the phone must have not actually been charging, even though the N6 always shows that it is charging. I haven't tested it thoroughly with the stock charger as I keep that next to my workstation, but it seems that others are having this issue even with the included charger. Frustrating, to say the least.
Same thing with my N6 on 5.1. I would say that 20% of the time i plug in it shows charging but doesn't charge, just maintains the battery at whatever percentage it was when i plugged it in.
I don't have to restart but rather just unplug and re plug in the charger, then monitor for a couple of minutes to make sure the battery is going up and if so it will charge normally.
I also have tried a few different chargers including the quick charger that came with the phone. same result.
the same. here
I have the same issue while charging n6 with Motorola terboxharger ... But it takes 3 h while charging with any other chargers .....any updates !!!

Wow, same here.... only just started to notice it. Using turbo charger as well...however upon using a normal charger, it seems to always charge. it it something with the turbo charger?
Yea it seems to be turbo charger problem , but how come I bought it just one month ago !!
I started noticing the same issue recently. I'd say it started after upgrading to 5.1. I'm using the stock turbo charger. I found a workaround that, so far, fixes it for me (3 nights in a row at least).
After plugging in the phone, I notice the battery icon shows it is charging. If I actually go into the battery settings though, it says it is NOT charging. If I unplug the charging cable and plug it back in while still in the battery settings page (you know, with the usage graph), then it starts charging just fine up until I get a full charge. As long as I do this each time, I seem to get a full charge. Annoying, yes. But not as annoying as waking up to à phone that never charged.
Sometimes it won't charge when it's not plugged in either
For my N6 to charge, I need to push the TC USB cable a little downwards for my phone to charge. Sometimes, it doesn't even charge at all. I'm considering to RMA this, if I can do it here in Norway.
my nexus 6 has different behaviours, if I charge it when it is turned on sometimes it stops the charging and I need to disconnect and reconnect the cable and charging starts again, so i need to be careful because i can't be sure that my phone will charge completely if i leave it alone. if I charge it when it is turned off sometimes it starts to restart continuously showing battery in the screen again and again, without charging. hopefully this happens sometimes, i dont really like this bug, i spent so much money for buying it and i dont want to control if my phone is charging or not when I plugged it, i just want to put in charging and coming bac when it is flly charged.
RMA it
I hope the first thing anybody does is check the charging port and make sure there's nothing in there. Take a strong, sharp toothpick and carefully dig anything out that shouldn't be there. Pocket fuzz etc...
I am having this same issue, my phone is brand new yesterday, running 5.0, I have these exact issues, seems to be only with the turbo charger because I use a slow charger for overnight next to my bed and the battery was full. But I can't seem to make the percentage actually go up with the turbo charger without restarting the phone first.
Any more info on this very annoying bug??
can't seem to figure it out
i have the same issue - my N6 is a couple of months old and it started on an overnight (not) charge. Now it's happening 1 in 2 charges so it's getting worse. I cleaned the connection, tried different cables, USB chargers and plugging into the laptop - no dice. It's going back to Google - annoying...
