I own 2 Note 2's the first one burnt while charging, it still works., but obviously does not charge anymore.
I replaced it with another one which also got very hot while in charge and had an electrical butning smell, but i got to it quicker and it is still in working order and able to charge, alrhough very slowly ie 5% an hour.
Is this a common fault with Note 2's ?
Also the battery will deplete in less than 4 hours from full charge just on standby using stock rom.
Am i unlucky or am i doing something to kill my phone.
Any opinions or advice greatfully received
No, this is not normal so perhaps it's a problem with the phone. To rule out the charger and USB cable, you might want to swap those, too, and retest.
I thought so. How widespread is this ?
I have 2 that have done the same thing.
I have tried different chargers and most of them dont work with my 2nd RMN2
I have not heard of this problem before. Either there is a problem with the phone itself, or (more likely, since more than one phone is affected) something is not right with your electricity mains supply. Do you have a surge protector/voltage regulator device/adapter?
Almost every charger should work maybe the output of the other charger were too low (and device uses up more than charged)
I got myself another charger (from Samsung with 5V 2A) because my old charger burnt out >_<

Did anyone try to use HOX+ in car as navigation? I have quite strong charger in car made for iPad (2.1A rated USB) and it is not able to charge phone when it is running navigation (Sygic, but it doesnt matter). It seems to me, that charging current is too low to charge battery and also power phone, which is actively used. Tried to repeat at home, again big Apple USB charger from iPad rated 2.1A and while I was actively using phone (browsing etc), charger was able to get 1% of battery charged per 15-20 minutes. Which is too long.
Phone is getting warm or even hot while using CPU actively (Chrome is able to run all 4 cores while rendering page) and maybe there is some protection to avoid HOX+ getting too hot while charging? Or maybe internal logic just doesnt take more juice from charger when phone is charging and being actively used (to power CPU/GPU and also charge battery)? Anyway result is that with intensive CPU/GPU apps like navigation, I cant charge phone fast enough and it is actually discharging! No matter how strong or good your charger is, phone takes constant current and sometimes its just not enoug...
Anyone got similar problems?
The problem is that you shouldn't use chargers meant for other electronic devices.
How is it with the charger supplied with the X+?
Bbattery Monitor Widget is good to track charge/discharge value.
I have not noticed anything out of the ordinary, even using the phone while it is charging.

And what is the difference between chargers with USB ports? I could understand that using cheap noname charger from China could be problem, but I'm using branded from Apple, which is known to be really well made. And it is providing 5V and up to 2.1A of current.
Anyway cant use original because I bought phone in UK and they have some ugly shaped power plugs unlike rest of Europe
...but it ain't working, obviously. A power adapter is like a couple of €s, and @amazon original charger are around 7 €

I've used both an OEM US charger and the UK charger with an adapter with the OEM cable and both have done fine. It does take longer to charge while using it, but that's no surprise.
The Apple charger should do better.
Simply put, the device reduces charge rate if the device gets too warm. I don't know if this is happening but it's something to keep in mind.
I had this issue also when i was using the device. Charging was stuck at 99% and did not change anymore.

Well, you probably can't top the battery while charging because the phone is drawing more current than what the charging circuit (internal to the phone) is able to deliver to the battery (while charging).
Been digging in this problem a little bit more and found strange pattern. Since I cant use original charger (UK version doesnt fit my outlet), I have to charge with Apple ones. I have one big for iPad3 (strong marked as 2.1A), one small one with 1A and one small one chinese copy from DX (also 1A). When I try to charge phone with first two, it just charge like USB (settings>power and there you can see type of chargin on the top of screen). When I use chinese copy, it charges like proper AC adapter, quite fast. But after while, touch screen is messed up and it is almost impossible to control my phone. It seems like some static electricity build up or something like this messing with toucscreen mechanism. It gets fine few seconds after removing phone from charger.
Tried different cables, have 3 types at home. Original cca 1m long, only chinese charger woks in AC mode. Then I have extra short for drive, same behavior like original and two long ones (2m), chinese from DX but well made with quite thick cable and with this even chinese sometimes charge like USB, but sometimes it connects like AC.
Always thought that Apple chargers are good and used them to charge other gadgets, never had any similar problems. Seems that One X+ is quite picky with chargers, anyone can verify if it is just my piece?
I have a ton of micro-USB chargers that I've used with my GNex and Evo3D with no issue. The only consideration I take into account is Amperage, and I toss the ones below 800 mAh. Last night I plugged into one thats around 850 mAh and left my phone to charge all night (at around 5%). When I woke up, the phone had completely discharged without any sort of recharge.
Since this isn't a Nexus phone, am I locked in to only using verizon branded chargers? Is there a way to defeat that with root?
I haven't had any issues with that as I use all different types. Maybe just try another or maybe it wasn't plugged in all the way.
What voltage is it rated at? It could be that or that the charger is bad somehow. I charge mine nightly with a .7A charger and it's always been full when I wake up (about 30-50% when I go to sleep).
I have the sprint note 2 but they are essentially the same phone so here is what Igot for you:
there is no "smart" element to any chargers in the market, so your phone shouldn't know the difference between Verizon brand and the devil's own brand
if you look at the stock charger it outputs 2 amps...the phone needs this and in my experience it needs at least 1 amp in order to charge instead of discharging slower
also there is a known issue with all note 2s that the cable will not sit snugly inside the port causing it to be a bad connection... just make sure you put it in hard (no pun intended) and it shouldn't be a problem

Yeah, if you take a close look at the micro-usb port, it is recessed a bit. Make sure you plug the cable in firmly.

I think this was likely the issue. The charger is rated at 1 Amp, and I tried it out again last night and it appeared to work for the few seconds I had it plugged in, so I must not have had it in there snugly.
So I just tested with the same charger, and when I plug it in, it beeps every half second and flashes between the charging/discharging symbol, and does not charge...

I don't remember where, but I remember reading about someone with this issue where they were using their phone as a gps while charging it and it died. Someone commented saying that the culprit was probably a faulty charger. Sounds like they were right.

I have seen this same thing with two Droid X's plugged into the same 2A charger. One phone would charge and the other would do exactly as you describe. It didn't do it all the time, it just depended on how low the battery levels were on each device. How much battery life do you have left when it does this? You may just need to use a higher amperage charger.
I have not received my Note II yet, but it sucks that I will most likely not be able to charge it while tethered (USB) to my laptop.
Based on the info I could find (kernel driver), the phone will accept up to 650mA of power, so anything over that should charge the phone at the same rate. Voltage shouldn't be an issue as it is charging via USB, which is 5V (+/- 5%). Unless someone has an amp probe to put on it, we can't tell if it is actually pulling more or less than what the driver specifies. And, as someone else stated, the phone can't tell if you're using a genuine Samsung cable and charger, or a $1.00 made in China cable/charger, as long as they both output the same voltage/amperage, the phone will never know the difference.
Based on what you said though, if the phone is constantly seeing the charger connect/disconnect, that would drain the battery even faster.
When plugged in, the charger included with my Optimus G buzzes. Audibly. It's pretty loud. At first I thought a fly was in my room, then I realized it was coming from my charger.
If I unplug it, it keeps buzzing for about ten seconds.
I have a Nexus 7 charger and a Atrix 2 charger. Neither have the same specifications as the buzzing LG charger. The N7 outputs 2 amps, the Atrix outputs 0.85 amps, the LG outputs 1 amp.
So... is it safer to a) use the buzzing charger or b) use a non-buzzing charger, but one that outputs a higher/lower current than the included charger?
I'm now afraid to charge my phone.
Anyone else having a problem where the charger buzzes?
Thanks.
UPDATE so apparently some googling tells me that it IS okay to use other chargers AS LONG as the voltages are the same. Amps can vary; even if the charger is rated for more amps, the device will only take as much as it needs, and if the amps are lower than the device specifications, it will just charge more slowly.
So my N7 charger has the same voltage but higher amps, so I'm just using that until LG sends me a non-buzzing charger (if they ever return my request)
If any of this information about volts/amps is wrong, someone let me know. But it seems right according to my limited knowledge of physics.

Never seen that before. Had a lot of phones with a lot of chargers and never heard a buzz, I'd get a new one just to be safe...but I tend to be super cautious
Weird, my charger (that I got with the OG) buzzes as well. I've been using since I got it and it hasn't exploded....yet.

Interesting... so it's not an isolated issue. My phone is four days old, which is why it's frightening me. I think I'm just gonna submit a replacement request, and keep using the buzzing one until that one arrives (assuming it's granted and I don't have to deal with any bull from LG). If it's a common thing for the charger to buzz and yet no one is complaining about an exploding battery... it's probably safe.
But I'll request a replacement just to be safe.
My htc inspire charger has always buzzed when plugged in to the wall but not charging the phone. My guess is it is a function of the transformers magnetic field and some metal part in the charger.
My charger buzzes too, when is plugged in and for a few seconds after like you described. I've been using it since launch day on this phone with no issues. The buzz has not gotten any louder or anything over the past few months so I wouldn't worry about it.
Running SnowJB
Switching power supplies like our chargers sometimes do buzz because of the way they work, and it may or may not be an issue. Usually it's an inductor vibrating, and it may last as long as you need it to, or the vibration may cause eventual failure), but since yours is still under warranty I'd definitely replace it.
Using any other USB charger will not be dangerous or bad for your phone since the voltage is standard. If it's rated for a higher current, great - the phone will only draw as much as it is designed to, so you can't damage anything that way. Battery monitor widget appears to tell me that it only charges with about 800mA of current (that is net; the phone is still using some additional current to operate), so assuming the correct current is being reported, it doesn't appear that there's any benefit from using a charger that can supply more than 1A. Unless it can draw more quickly when charged with power off -- I don't have any good way to check this.
On the other side, while you can use a charger that's only rated for 500mA, which is the old USB standard current, the phone will charge more slowly and you'll probably get the warning saying so. It may not actually even supply enough current to charge the phone while you're using it in that case. So while you'll get by in a pinch for an overnight charge with one of those, it's well worth investing a couple of bucks in a higher-rated one.
I normally use my kindle fire charger which is rated for 1.9A (and the Fire can draw that much) or my New Trent battery pack which is rated for 2.1. My LG charger stays at work and doesn't get much use. I'm going to eventually buy another charger for home and I'll be looking for one rated for 2A or so.
Beeping
My charger is beeping after the battery is full. Its very very quiet but I hear a rhythmic beeping.
Hey, been on these forums for a while, I rarely ask for help (been pretty lucky with the phones), but I have a question.
My phone won't charge. Or rather, it requires a time consuming process of fiddling, unplugging, replugging, and sometimes minor surgery on the USB port with a toothbrush or a tool I've crafted out of a Q-tip. However, after a night of charging (or some interrupted equivalent that results in a charged battery) the battery quickly depletes while still plugged in.
This is most clearly illustrated when yesterday, at 8:45 I rolled over and checked my phone to see if it had been charged. Pleased to see that it had been charged up to 100% I fell back asleep. When I woke up again to go to school at 9:10, my phone was entirely dead. I couldn't even get it to turn on to the point where it showed the I9100 screen. After following the time consuming and frustrating process of fiddling with the USB port and Micro USB charger, I coaxed the phone to show the powered-down charging screen, where I left it to charge to full.
I have been experiencing this over the course of a few weeks and I have tried many chargers, but only one of them will work at all (Interestingly a Motorola cord). Upon inspection of the USB port, nothing seems out of the ordinary, though the 2 prongs on the outside of the USB port male receiver look slightly different than the inside 2, though they difference is symmetrical.
Does anybody have any idea of what could be plaguing my phone? USB or battery? This is my second SII, a replacement one after my original one was tragically lost in a hot tub . Any thoughts would be awesome.
Thanks

If you are using Siyah kernel have you altered the charging current through EsTweeks?
If so then it is possible that the battery / charging circuit has been damaged. Try resetting the values to default (I think its 700mV on AC and misc and 600mV on USB but dont quote me).
Failing that then some hardware trouble shooting (trying a new battery / external battery charger) will help you figure out what is going on.

My signature is quite outdated... Currently just running CM 10.1 with stock everything. Haven't tweaked anything in that capacity... but will try my other battery (if I can find it). Thanks!
I was having this same problem with my HTC vivid. I tried charging with may chargers, the phone claimed it was charging (orange light lit up) but the phones battery was dying while plugged in. Just like you said, the battery depleted rather quickly when plugged in. Since my phone refused to accept any form of charge I bought an external battery charger and some extra batteries.
However, last week I wondered if maybe there was some sort of dust, or small pieces of sand inside the Micro-USB port on my in my phone that were possibly "blocking" the charger from properly charging.
So I bought an air duster and blew air into the USB port of my phone. I guess there must have been something in there because that fixed my issue and now my phone charges!
Now I have 4 batteries for my phone and an external battery charger.
Try it on your phone, see if you have the same luck I had.

Maybe I'm missing something here because you seem to be experienced on this forum and understand about searching first.
Anyway, this sounds like the common USB problem that S2s have. It can be the jack or more typically, the flex cable. You replace the little board. Search for USB in this forum. I just changed mine with one I got on Ebay. Cheap and easy.
Hello XDA,
I'm not sure how this happened, but for the past couple of months I haven't been able to charge my phone while it is turned on. It shows the charging animation but the battery still drains, even with all radios off and screen off. I can leave it charging all night and end up with a nearly flat battery. Plugging it in to any wall socket seems to only slow the draining, and plugging it in to a fully powered USB socket (many tried) keeps it at the same battery level, or very slowly charges it if I don't use it. If I turn it off however, I can charge it until full in the normal time with the original AC charger.
Here's the really strange part: I've tried several new chargers of different brands including samsung and it makes no difference. Not only that, but they won't charge it when powered off either making them completely ineffective. It doesn't initialize the charge properly - the screen either shows a battery with a progress circle over and over again without getting to the charging animation, or displays the charging animation over and over and never charges at all, but nevertheless gets hot.
The chargers I've tried are:
Cygnet for samsung phones including SGS-II
Belkin for Samsung phones including SGS-II
Premium blackberry travel charger
Premium 10W 2A Samsung travel adaptor
One charger that did seem to work while plugged in was from a new Sony Xperia Windows phone charger I borrowed once.
I've exchanged at the store 3 times now with the same result! It must be something wrong with the hardware or software...
I've calibrated the battery, I've had a new battery for a couple of months and normally still lasts all day and more on a full charge. It is a 3rd party high quality Anker battery. The problem is the battery is getting a lot more taxed now that I'm using 3G over the portable hotspot, so its not quite lasting the day anymore.
I've had countless custom ROMs on there now, current ROM is CyanogenMod 10.1 stable. Would returning to stock then reinstalling help?
Something that shouldn't matter is I've moved from the UK to Australia. I'm still using the English charger as its the only one that works. And the Xperia charger that seemed to work was Australian too.
Before it got this bad I think it was getting slower and slower to charge. I had to replace the old USB cable that eventually got really loose, then broke and i've tried several new ones with no improvement in charging ability. Is it possible that the contacts inside the micro-USB socket might have been bent from the old cable moving around so much so that only minimal contact is achieved with any other cable? The new connectors do seem to fit perfectly.
In the attached screenshot, you will see on the left the AC charger is plugged in while battery level goes down, then on the far right its plugged in to a computer and is kept level.
Any suggestions would be greatly appreciated!!

IMO, u should revert back to a stock samsung Firmware (pertained to ur region) and then see if the issue persists or not to rule out any possible 'Software issue' in the first place
