This problem was there since i bought the nexus 5 (first week of jan), but it used to happen seldom, like once a week or so. But since last 2-3 weeks, everytime i try to charge my phone, it doesn't charge and actually starts discharging and reaches 0% in some time while charging, one way i have found to solve it is to switch off the phone while charging, let it charge like that for 5 mins, and then switch back on, it gains 1% during that time, after that it charges normally.
Using original charger and USB cable that came with my nexus 5, tried using samsung charger and HTC cable with HTC charger as well as OEM charger, doesn't make a difference.
Also, since i bought the nexus 5, if the USB cable is even slightly displaced (like when picking up the phone), and phone disconnects and reconnects from charging, like the port on the phone is loose or something, this annoys me while transferring data from pc as if the phone is even slightly moved, then the Internal Storage unmounts and remounts on the pc, thus interrupting the transfer. Though this problem i have noticed is slightly higher when phone charge is on the lower side (~20%) and if i try to fiddle with the USB cable while the charge is >60%, the problem doesn't seem to be that much, though it still disconnects, but not that sensitive.
Can anyone explain what's going on?
Does the mobile display that the phone is actually charging when you have connected it to the charger??
As for your second problem, I'm sure the micro usb port of your device has become loose... Nothing you can do to fix it... May be visit a local LG centre and tell them to see if it can be fixed by opening up the device and tightening it may be?

Yes, the phone says charging, battery settings says Charging (AC), but it doesn't charge, and discharges, i don't think that some app is using high cpu while charging, because my battery discharges fine before i put it on charge.
I purchased it from Play Store, so LG would fix it then too?

Are you fully stock? If so, then perform a factory reset and see whether the issue persists. If you're using a custom rom then flash the factory images and go fully stock and see whether it still occurs.
If it does, then it's surely a faulty battery we are looking at. Since you've tried using different chargers and cables, there's nothing more you can do.
Call google customer service and RMA it.

Yes, i am running stock rom with root, tried factory reset, no improvement, currently my phone is on charging with 71% charge, now i am using my phone, testing new camera app, no disconnections, but when i use the phone with low charge while charging, it disconnects and reconnects, don't know if it's hardware fault or just software, as charging too returns to normal when phone is switched off and then turned on.
Is RMA'ing the last resort? coz i am afraid that RMA might lead to some other problems, like getting a replacement with screen bleed issue or some else issue.

Yes, what you've said is very true. The replacement device might have other problems if you're unlucky.
Are you on stock kernel or have you flashed a custom kernel? If you have then flash the stock boot.img and see.
If everything else fails you can flash the factory images from Google and go completely stock and see if the problem persists.
It's upto you to decide whether you can overlook this weird battery issue or not. If you can't, then RMA is the only option left.

hmm yeah, i would need to think about it, thanks for the help.. :good:
i think i'd wait for 4.4.3 first to see if it isn't a firmware issue.
This results are from my tests.
If your current CPU operating temperature is higher than 51 degrees celsius the phone won't charge,it will stay at for example 50% .
If the temp. Is higher than 51 degrees the batt% will decrease.
If the temp. Is below 45 degrees the battery will charge but very slow.
If you're gaming it's normal.
Leave your phone to cool down for 20 minutes and it will start to charge at normal tempo,1-2% per minute at 20.degrees celsius.

In my case the battery isn't charging or it's charging BUT at 1 percent in 7-8 minutes when CPU temp. Is 51-52 celsius or above.
Sometimes when it's above 55 celsius,battery percentage is going down.
I'm charging with the original charger and cable.

Yes, that's normal. It will charge if the temp is above 50*c..it will charge slowly as you are using your phone for hd gaming which takes a toll on the battery..
Fast charge just means that you can charge via your computer at AC wall charging speed...
If you charge your phone via computer and play games on it simultaneously then it's normal to discharge while charging as usb charges only at 0.5amp

ok, so after some days of testing, i can say that this problem is irrelevant of temps on my device, sometimes it charges without any nags, but most of the time it discharges while plugged in, and i have to reboot the phone.. :crying:

This happened on my last phone. For me, it was from using a USB fast charge option on a custom kernel: reflashed the kernel and charging was back to normal; selected the option and it duplicated the problem.
So:
Are you using a stock kernel? Either way, I would try wiping caches and flashing the kernel (or another one).
Or, if you haven't, try a simulated battery pull (hold down the power, volume up and volume down buttons for ~15 seconds).

I know when I'm using my phone as a sat nav on the car dash it can get pretty toasty. When it's like that, it is on charge but the phone will still drain slowly... so on a 3 hour journey it may lose 20% battery or something. That is with an official HTC car charger so perhaps the results are a little unfair - think it's rated 1 amp.

yeah, while discharging, no matter how many times i re-insert the cable, or change the charger or the cable, it won't charge unless i switch off the phone, let it charge for some minutes and then power it on, it'll start to charge normally after that..
I'm in a similar boat. Every now and then I'll wake up with the battery being only charged to 75 or so. Since it happens sporadically it's hard to test why it may be happening. Have you found any resolution for the issue? This is using a wireless charger so a bad USB port can be ruled out.

The Nexus 5 has a charging controller by TI, that regulates the voltage and current to the battery if the battery gets hot enough lets say 50C it will stop all charging untill the battery is cooled and the charging session is re-started
The battery also has a fail-safe measure to prevent the phones battery from exploding which also does what the charging controller does, incase it fails the battery has another fail-safe mode

I've noticed that the battery meter will sometimes stay at 100% for a while and then all of the sudden drop to the actual percentage sometime later. A reboot after unplugging the phone will fix the problem and report the battery % at the correct level. I was wondering how many other people were experiencing this, or if it is just a hit or miss thing?
I'm still on stock, unrooted, no mods. It's a straight out of the box Skyrocket.
Also, does the problem remain after rooting, modding, etc.?
I asked this on the battery results thread in general, and only received one response, so I figured this would be better in Q&A.
I had the same issue, but it has only happened one or two times.
Showed 100% for hours then rebooted and it showed 73%
I don't know how long you've had your phone, but it takes several cycles from full to empty for the battery to calibrate correctly. During that time you can get some really funky readings on it.
I am experiencing the same problem.
I've also had a hard time charging the phone. I've left it plugged in upwards of 18 hours, only to find it saying its only 83% charged. That may just be another symptom of the same problem though.
Do you think this is a phone or a battery issue?

That sounds like you were plugged into a pc vs ac power and had heavy usage during that time.
Mine charges very quickly when at idle and plugged into the wall.
I've had my phone since the day it launched (the 6th) and just experienced this for the first time yesterday. It was indeed quite odd to see.
I have had this happen one time. I also noticed the phone got very hot.
It actually happend yesterday, stayed at 100% almost all day then just shut off and wouldnt reboot.... freaked me out!!

I think that the battery is pretty wonky. I am not sure if the NFC addition is causing these issues but some people are having amazing life ans some people (me included) get horrible. I am getting a warranty exchange on my battery. No way I should drop 12% in an hour and 20 minutes when the only usage is 19 minutes of checking email. If I have to have it plugged in every time I turn around it is not exactly a wireless device now is it?

Strange, I was just reading this thread and thinking I have never experienced this. Then I checked my battery stat and it showed 100% even though I've been using it for an hour and a half. I restarted and now reads 90%.
Had my phone for almost a month. Rooted only on stock ROM. Just took it off USB cable from laptop an hour and a half ago.

I think we narrowed it down to being a bad charging circuit in the phone or battery triggered by a .1a charger.
When we got our new skyrockets they stopped doing it.

I was powering my phone off, plugging the power in and allowing it to recharge. The phone would automatically power on as soon as I connected the power but I didn't think that mattered. It turns out it did. If I powered the phone on and then connected the power, the battery meter would work correctly.
This was different the Captivate I had previously. That phone had the capability to charge while powered off. There was even a charging graphic that displayed while the phone was off.
The Skyrocket did not have this same feature when I originally bought it. However, ATT did an update at some point and now it does. I've been unable to re-create the stuck battery gauge since that update.
please only use the charger that came with the phone. other chargers, after prolonged usage, may cause issues.
The charger that came with most skyrockets is a .1a charger and causes the issue as well. A few reported getting .7a chargers in the box but most have been .1
I have tested the iPhone charger theory on 5 phones now. Phone 1 and 2 experienced the issue. Phones 3-5 did not
Its more than just the charger. The phones experiencing this either have a bad battery or it's in the phone

From day 1 with the skyrocket, I have used an old wall charger and cable and had this problem daily. I plug it in at night and in the morning, it's at 100% until I reboot, or some other random event that drops the percentage to the real battery stats.
Because of this thread, I dug out the box and used the wall charger and cable that came with it, and this morning shortly after unplugging the phone, it was at 99% and dropping, just as it should. Very glad I tried this.
Ummm no.....

I did a recheck of my black cube SR wall charger (Samsung part # ETA0U80JBE).. It is NOT .1a it is 1.0amps - which - interestingly enough is EXACTLY what my iPhone3g power cube right next to it delivers.
The .7am Samsung charger has the usb connector on the side, and is part number ETA0U60JBE - delivering 5v at .7 amps (30% decrease over the little cube device). That was the charger my SGS-II had. My S/R came with the 1.0 amp ETA0U80JBE version.
One amp will charge the phone MUCH faster than the USB port. Per the spec, the typical USB device cannot drain more than 500mA (1/2 of what the power cube supplies to the phone).
Unfortunately Apple and Samsung both have the cubes pretty well locked up, so I cant compare the components, but at a first glace they appear to be absolutely identical, both putting out about 5.1 volts at zero load.

I had the same issue for a bit. Someone said to try disconnecting and reconnecting the usb from the power block about 4 or 5 time relatively quickly and that fixed it for them... tried it and have not had an issue since even when connected to an extension. But also make sure its firmly in.
Oh.. and do this with the note plugged into the mini end of course
I have to say that I have been very happy with the crazyondigital wall charger that was bundled with my case. I used the OEM charger for the initial charge but began using the crazyondigital charger because it's more convenient due to the fact that it's longer. It also seems to charge more qiuckly. Perhaps slow charging with the OEM charger has something to do with the USB wall wart wiring design.
I seem to have the same type of problem I had mine on charge for 2 days now I done nothing different in the way I normaly charge, I tried both having ny note off over nite and with it on both with no luck, both time my note not fully charged.

Had the same problem yesterday. my note went out of energy and shut down. So, after a while I connected it with the cable to charge. And what happened? After a hole night I got only 50% -.- I was like wtf?? then I tried the galaxy s3 charger and there was a red cross on the battery icon. Then I tried the note charger, again nothing, and like the other poster said, after a few times in and out it worked again.
another one here with slow charging, this is a big problem, its so slow it means it drains when you are using the tablet when its plugged in, you should be able to use it and charge at the same time. I could understand if it didnt charge much when I was using it but to not charge at all is a real fail.
Has anyone logged this issue to samsung?
Nothing has solved this problem for me.
Taking 8 hours to charge 79% is just beyond comprehension. Can't use it plugged in as it drains anyway. I want a update asap or I'm ditching this tab.
I don't know what caused this, it was fine a few weeks after the update and suddenly crippled.

So it's not the update then? If it was fine for a few weeks and then suddenly crippled JB is not the problem.
More likely an Application is NOT properly compliant with JB and is draining battery or hogging

Nothing shows up as running and hogging the battery. It doesn't drain fast once charged. It just charges slow.

Indeed, it charges so slow it drops when you are using it plugged in, if anyone has registered their tab properly with samsung perhaps they could log a fault, I havent had chance to do this yet.
Also, has anyone tried switching back to stock to see if it resolves it?
My SGH-S730m (no device forum for this phone yet) battery percentage was at around 80% when I turned it off. It was placed in a pocket with another device. I can 100% confirm it was off for a complete 4 hours.
When I turned it on, the battery level was at 5%.
The battery still charges, the phone still works. The battery has not exploded yet, and is currently at 45% charge. I am using samsungs OEM battery (it came in the box with the phone). I have had this phone for just more than 2 months now.
What the heck happened? Is my fuel guage messed up?
Have you ever tried battery calibration?
1. Charge phone to 100%
2. Discharge to 0%
3. Let phone sit for 5 minutes
4. Plug it in without turning the phone on
5. Charge without break to 100%
6. Repeat 2-3 times
I also is same...

That might be a fix, but im looking for the reason behind this problem.
Does anybody know what went wrong? My phone still works (if that even means anything).
Sometimes it happens that the chip goes mad. It happens with every android phone. You're lucky that you have removal battery. Some devices is difficult to do the above trick. I think when you do a full charge and disconnect the battery from the phone for 5 minutes it will be good again. I'm not kind of advice let battery go to 0 because you can ruin li ion battery with a full discharge.

I don't know where you from but in Europe you have 6 months for battery and 2 years for phone.

What I meant was, if it's still within it's warranty period you should get it exchanged.
If not, swap your battery with someone and see if it's your phone or the battery.
Indeed.

I won this phone for $7 at a stack-em machine. I doubt it has warrenty.
Sorry pal I can not answer that. But try the exchange battery suggestion from the other user. And try mine for calibration.

Is this a one time only issue or did you get that a lot?
One time only can be from a stuck process in your phone
If you get that a lot => try the warranty

One time issue. I noticed that the phone was getting really hot (even though it was off).

...I'm not kind of advice let battery go to 0 because you can ruin li ion battery with a full discharge.

Nope, you can't. It reads 0% while actually it's voltage is way above 0mV (actually somewhere above 3V) and that's a preventive so that you can never discharge it even close to full discharge because going over 0.5V below the nominal voltage would ruin most Li-Ion batteries so it simply doesn't even allow you to do that. And besides, from where do you think it draws the juice to blink the LED when you try to turn the phone on after a "full discharge"?

You should buy a replacement battery then ASAP, they're pretty cheap these days. You don't want Li-Ion packs overheating and the liquid inside them catching on fire.
Li-ion battery are intended to work between 40 and 100 working below that is in most cases the ruin of a battery. And experts say even 98 % slhould be optimal full charge not evem full.

Can you please quote some sources and prove that this is not just a speculation by yourself? I understand the physics of electricity and the foundations of marketing and economy well enough to say that what you wrote is utter nonsense.
Just read the thread from gokhanmoral from here. On galaxy s3 original development thread.

I already know what the problem is. What I want to know is "what" happened to the battery.
Why, would the battery die so quickly when the phone was off? Why, was my li-ion battery discarging the energy as heat? (which would expain the heat while it was off). Why, does my phone still work?
Years ago, I fried a pocket pc by using a 10A charger instead of the usb 0.5A standard (is it 0.5mA? - I cant remember anymore). The battery didnt actually explode, but it got HOT! Really hot. I came back 10 minutes later to discover that my battery was discharging while plugged in..
I fried my fuel guage hardware. Tried to save it, but there was no way. Even after unplugging the 1 pound beast from the charger, the phone was discharging around %4 every 30 seconds. I learned my lesson from that horrific event (I loved that phone so much).
Now, who "actually" knows what happened to my battery? Anyone? I dont need a fix - so dont bother posting if your going to tell me to buy, sell, or repair, and not tell me why.
My phone's battery goes down if it's charging and the data is on until the phone dies. I'm using miktouch and Hyperion's extended battery. It also doesn't seem to charge fast at all (12+ hours). Once it's "dead"it will power off, then randomly go back to 100% battery (orange light to green light).
Anyone else have this issue?

First guess is you have a defective battery. Draining while connected to the charger should never happen with a good battery.
I guessed as much too. These Hyperion batteries go bad quickly. I've had five since January.

I just got mine. It says to not use more than 4.2V to charge it. My chargers are all 5.0V. What kind of danger am I playing with buy not buying a compatible charger?

With LiPo batteries there is the danger of explosion/fire. I have an Anker universal charger and note that the output when plugged in is 4.2V. However, USB ports output 5V, so I would think the Anker battery can tolerate that otherwise you would not be able to charge the phone by plugging into a USB port.

I hope so too.
So, brand new anker and the battery still decharges when plugged in and goes full charge once the phone is off. I'm thinking there's something broken with the phone and not so much the batteries.

From a lot of the comments in this forum, I suspect the phone has a charging circuit controlled by software rather than hardware. Before you do anything hardware drastic, you might try flashing a different kernel.
Also, you report that the battery leaps to 'full' when you disconnect the charger. Have you tried measuring the battery voltage physically with a multimeter to see if the battery is charging at all. Should be 4.2V when fully charged. Something like 3.6V when empty. Obviously if you put the battery in for half an hour and the voltage goes up, it's charging no matter what the UI says!
I've not tried either of those. I don't completely understand what the kernel is. I'm using Miktouch rom, but I don't know how much that has to do with the kernel. I know the battery is being charged because if I leave it plugged in for a good 8 hours it holds its charge for the day. And if I leave it plugged in for say, half a day, and turn off data/wifi, it will slowly show increased charge, like a percentage per half hours of charging.
What do I need to know and do to flash a new kernel on here?

Your the only one of my users to ever have this issue, including me. And the doubleshot was my last device before going Nexus last February.
What I would do is:
1. Backup all your user downloaded apps with Titanium Backup.
2. *Do a full wipe from recovery*
*Wipe data/factory reset
*Format system
*Format Data
*Format cache
3. Flash MikTouch and reboot.
4. Once rebooted don't go cramming apps and settings back into your phone just yet. Make sure its going to charge and drain like its supposed to. If all is well, then start 1 by 1 with your apps, making sure each of them are not causing your issues. If all tests are passed then something in the ROM its self went stupid.
Sounds like hardware though.

Thats normal dude...if you use your phone while its charging you are using the energy from the charget to use your phone and to charge your phone...Faux kernel has the ability to lower you cpu speed to avoid heat but its pretty normal for the phone and any other device you have to heat while charging!!!

This, everything gets hot while being used
Like a engine it gets hot while being used
Your phone should get warm, but not hot. If it's getting hot, then there's a problem.
If you're not sure whether the phone is warm or hot, then it's simply warm. You'll absolutely know it if it's hot. Also, try letting it cool (as you've done), then put the phone back on the charger at as close to 100% charge as you can. Once you're at 100%, touch the phone, then wait 10 minutes. If, after 10 minutes, it's significantly hotter than before, then something is probably wrong, because your phone didn't go into "trickle" mode, like it should. If that's the case, I'd be more inclined to look at replacing the charger, than the phone.
My phone barely gets warm to the touch solely from charging. In fact, the battery temperature usually drops and holds at about 26C when I plug in.
Are you using the phone heavily while it's charging?

Its very normal case for every smartphones. However,
Try plugging in another charger if one is available and see if the issue persist. If the charger is defective you can process you should discard immediately or process for a warranty return if still under warranty.
Remove the battery door and battery from the device, inspect the battery and battery connections. Ensure there is no damaged to the battery, battery pins or contacts on the device. If you have damage to the battery or charging pins, please discontinue use and submit the phone for repair.
