For the last couple months, when I plug my nexus in to charge, it intermittently stops and starts charging. It doesn't always do this but when it does you can tell because the screen will stay lit up with the "charging x%" label flashing under the clock. The screen stays lit and the charging label flashes because it is as if you are pulling the charge cable out and plugging it back in over and over again.
I think I read about this issue a few times awhile ago but I can't find any mentions of it now. I know it happens with the orb charger sometimes but I just use the stock LG charger and cable.
Does anyone have any idea if it would be my phone, the charger, or the usb cable?
I sort of thought maybe after plugging it in so many times (since I got it basically right after it launched) maybe the usb mini charging port got worn down so it has enough play that the charge wire can't always get a grip on it leading to the intermittent charging connection. My charging cable hasn't ever been bent around much so I don't think it would have been damaged.
I am running the latest official CM nightly with faux's kernel. This problem has happened at least twice when I was running it completely stock as well as each time I tried several other kernels. Formatting and restoring never helped either. So I doubt it is a software issue.
Usually when this happens, I think it also winds up switching to usb charging mode because charging is unusually slow. I'd say 90% of the time though if charges without this intermittent issue and in AC charging mode very quickly.
What happens when you connect your phone to your PC? Does it work, or does it connect and disconnect continually? Does it charge fluently?

On a PC it's a completely solid connection. It has always charged solidly from a computer.

I have tried one other charger and wire a few months ago but I only used it for about 10 minutes. I'll try it again today and charge it overnight for a better test. It didn't have the same issues but the plug was definitely tighter to plug in. Could the lg charger's cable have worn down or is it just not made to fit a tightly? The LG wire does wiggle a tiny bit while the new charger wire doesn't move at all. Does your LG usb cable have a bit of play?

Mine doesn't wiggle, but that wouldn't be the problem. If it's charging fluently while connected to the pc, then the adaptor itself might be the problem.

Can you RMA a charger with google? I think you're right. Right before the problem starts, the charger starts making faint intermittent buzzing noises. It's not an unusual buzz, it's that normal sound that you often hear with chargers and other devices. The thing that's weird is that it is intermittent instead of a steady sound. I'll see if I can get it replaced.

have anyone got issues with S2 when plugged into power?
ie when I start recharging direct from 240V adapter, my S2 started getting VERY laggy and slow.
It immediately goes back to normal response when I unplug power.
I have never problem like you

Try using an alternative charger...probably your mains charger or the usb connector on the charger is damaged.
I'm pretty sure its a issue with the s/w as I have used the charger on another phone without any issue.
unless its one of the apps I'm using, not sure how to narrow it down.
mtrax...
I have the same issue.
You´re not alone...LOL
FYI the common issue I have when plugged in is that its not easy to unlock screen, takes me a 2-3 swipes to unlock screen and after that it seems that it ignores every other key press..
Any one reported this to Samsung? I will try to log a ticket to see what happens.
Try do a multi touch test while its plugged in see if the screens acting funny.
how do I do a multi-touch test?
what will that prove? as the screen works fine when unplugged.
I have the same issue but only when charging with the usb lead (with usb power adapter) instead of the standard mains charger. Think it might have stopped now that debugging is enabled and the Samsung kies screen doesn't come up when i connect the usb.
Sent from my GT-I9100 using XDA App
Took my phone 2 hours to charge from 36 % to 100 %
note this issue doesn't occur when charging via PC ONLY via 240V mains, but let me try with USB debugging on.
edit tried USB debbuging still has issue.
Note is the 240V USB cable different from a normal USB cable? ie perhaps the device thinks its a PC connection
the phone is laggy because of the electrical interference from a faulty charger or some other electrical equipment in the near vicinity...
Please note that actually the capacitive touchscreen becomes laggy not the applications/services...
keep it away from the electrical interference...use the samsung original charger..gud quality USB cable....and the issue will be gone... for sure
looks like its the charger, the A/C adapter I got with the phone was UK which is why I didn't use it to begin with, but tried the samsung one with a UK/AU adapter and its fine..
hmm who would have thought that was the issue...
interesting it didn't affect my other HTC phone.
Same issue here, but something special:
I ebayed another charger for my sgs2, original samsung one. Same serial number, same description, same style.. but i got the charging problem only with the new one.
With my original charger (the one, which was delivered with the phone) works fine. No slow and no lag.
The new one was about 5 euro, seems to be an original...
to demonstrate my point that its the electrical interference from the dodgy chargers onto the capacitive touchscreen... do this and report back...
plug the faulty charger onto the socket BUT DO NOT charge the phone with it...
keep the phone near to the charger wires etc....(not in charge)... you will see the screen lagging sometimes unresponsive...
now move the phone away ...it will work fine..
you can keep on using the dodgy chargers for charging...but use the phone only after it has been charged and is away from the charger...

I am not able to reproduce that with my original charger. There is no lag or any other problem. Switching to my second "original" (ebay 5 €uro) samsung charger leads me direct to the lag and your description. First i thought my second one is not an original one, but because of your description there seems to be a diffrent quality on the original charger depending on it production date.. unit.. charge.. or whatever.
I bought a sgs2 from the UK, and have a UK to AUS converter on the stock charger and I have no lag when it's charging or near chargers.
Sorry. Not a problem here. Writing now and plugged. Very responsive.

The electrical interference with the capacitive display is bullcrap since it needs electrical properties to respond. So it depends on whether your body has enough electrical properties.
So back to the point:
It is due to CPU reducing the clock speeds to prevent the phone from overheating as the battery itself produces enough heat anyway.
Many other people may not notice it since they may not perform intensive tasks while the phone is plugged in and the variation itself is also almost unnoticeable.
I have the same issue but as I said, it's almost unnoticeable to even bring it up in this forum. I haven't done any testing myself to prove this, but the same safety feature is implemented in most modern phones.
I have the same issue - I also had this issue with my Atrix.
I usually charge my phone using USB while in the office. At home, I'll use the supplied wall AC adapter.
I've noticed that even though I'm using the AC charger, the stock battery display will show Charging (USB), which is not the case. Power cycling the AC charger usually fixes it to show Charging (AC).
Have also noticed that in some instances when it's plugged into the AC charger, the charging status would switch between "charging" and "not charging". Very obvious in the notification battery icon, where I would see the lightning symbol appear and disappear, about every half second.
I think there's an issue with the AC charger, or maybe it's the charging circuit in the phone?
Anyone experienced something like this before?
Cheers

Sounds like a hardware issue. If you want to run the test yourself, you can try swapping the charger with another OEM Nexus 4 charger (don't try to get around this). But I'd contact Google about this if I were you.
Might be the stock charger if thats what your using i had the same prob and sometimes but battery would either stay on the same percent for a while or go down so chanhed the charger and its been working fine ever since i still use the stock box charger i just changed the cord

i had similar issue..when plugged it shows charging/discharging..if charging it will be slow as hell..swap cable all good..
throw away the original cable try a different one..
Thanks. Will give it a shot and see how it goes.
Do you guys think this is a charging issue? Temp is very high but still continues to charge at AC level. I have switched out my power bricks and cable but still have the same result.

It is due to temperature I believe. I have observed this behavior closely for a long time, so I'm almost certain this is the cause. I've seen it on the Galaxy Nexus and the Nexus 7. I can't tell you offhand the exact temperature they stop charging at, but I can tell you it's most likely between 50°-60° Celsius. You've got to let your devices cool off. It may be a pain, but it protects your hardware, so when it stops charging, your phone is saying "Hey partner, you think you could let me cool down for just a second? Is that too much for you or what? What's your problem, you dingdong?"..
... Or something like that. If that's not exactly what it says, it's very close.

Ah I see. Anyways, I have used my cousins nexus 4 and every time the temp goes over 38 degrees, the charge rate drops down to USB. Mainly why I asked haha. Yah its a pain from time to time LOl

Same here. Worked out for me it was a dodgy cable. Using the supplied cable through a laptop, I will also from time to time get the plugged/unplugged notification on the computer, which being audible made me realize how often it was happening.
The supplied charger brick now seems to work flawlessly with a different cable (ie, always says AC, no odd charging/not charging behaviour, etc).
Try that and see how you go.
I guess it's the cable. I've tried using a generic ebay cable and it appears to be working fine now.
What sort of mA values are you getting when using the stock AC charger?
Battery Monitor widget says that the phone's only getting around 500mA when I believe it should be getting more than that. I've enabled the USB fastcharge in the options. and have left everything at default. This is after waking up the phone from standby. Keeping the screen on drops the charge rate to 200mA thereabouts.
No music playing, 3G and connected to a wifi access point.
phone only started doing this over the last couple months, used to be able to plug in (either charger / cable) and charge in AC mode without supervision.
Nowadays, it takes several plug in attempts to even START in AC mode, but typically it'll drop down to USB (the screen comes on momentarily when the change occurs) at some point in the charging.
Worst case scenario, it'll change rapidly back into AC and out, to the point where I can watch it on happen on the screen. That's rarer though.
It never changes INTO AC and stays there, to be clear. Always a downgrade to USB charging.
Is something wrong physically with the jack on the phone? I've never damaged the phone, dropped in water, etc.
If RMA is what's suggested as my only option - is that a brand new phone or refurbished?
Use another USB charger, its a known problem with the supplied LG charger with the N4. I myself have this problem but am using another charger and its fine.
The USB cable has no problems btw, its the charger itself.
Can you link to your sources on this being a "known problem" ?
I'm pretty sure the same issue persists with my old Samsung charger too - the one supplied with the Galaxy Nexus. So.. that suggest the problem is with the phone, not the charger/cable.
i also have the exact same problem just now.. i'll try using another charger tonight at home..
just now i charged my nx4 using its original charger, in just a couple of minutes, the phone is saying that its being charged using usb.. stupid..
I'm also getting this at the moment, I'm completely stock, not even rooted and this has cropped up only since the 1.8mb Security Patch....
Any fixes?
Will root if I can fix it....
I was/am having this issue as well. I typically charge my phone via car charger (works fine) or wireless, so I can get around this issue easily. Plugging it into the PC and enabling fast charge with franco's kernel works as well.
I tried my N10 charger and it was dropping to USB as well. When I'm at my friend's place and use his generic charger, it works fine.
I used to have this issue but ever since I updated Android to 4.3, my charging works just fine.

Might try a factory reset and see does it make any difference...
do we have any more thoughts on this issue? is it a software bug? is it hardware? which hardware? I am going to experiement with a few different wall chargers and usb cables.
so 3 chargers (Galaxy Nexus' , Nexus 4's, USB 3.0 port on PC) and 3 cables (likewise + cable from monoprice)
SEEM to yield the results, that the problem is the connection between the cable and the phone. The oldest and most used cable has the hardest time establishing and maintaining an AC connection, the newest/lest used one from monoprice has never had a problem, and the LG cable is in the middle.
Is this an issue of wear and tear on both the cable connectors and the phone's port? It's really lame the phone and it's cable are not even a year old and THAT can't stay charging at AC voltages.
Will a replacement phone from Google be a refurbished unit or brand new?

They will send you a new (not refurb) phone and you will have 21 days to send back your old phone. The replacement process is super easy, just call them at +1 855 83NEXUS and tell them your issue. They will walk you through a factory reset and if the problem is not fixed they will replace it.
I've had issues with the microusb port on multiple phones in the past, and have definitely noticed the N4's socket getting looser.
On an old HTC sensation, I had to resolder the port on. Can you reproduce the behavior by applying slight pressure to the plug in various directions?
Does your connection also intermittently drop out when connected to a computer?
A workaround for the time being could be to use a kernel that allows you to force fast charging regardless of the detected charger. But at that rate, it's quite possible you'll lose your usb port altogether sometime in the future..
You could also enable adb over wireless, and check the charger type:
Code:
cat /sys/kernel/debug/msm_otg/chg_type
You should be seeing DCP (has the data pins connected, possibly with some resistance).
Or proprietary if you're using an Apple-compatible charger (has aspecific voltage on the data pins).
If you see SDP, it means it's in "USB" mode.
If it's staying DCP/proprietary but the charge rate is dropping to "USB," it means the phone is throttling down the current because it's detecting the charger can't deliver (voltage dropping below threshold).
with the good cable (monoprice), wiggling has no effect.
with the poorest cable (samsung), wiggling will rapidly change it between AC / USB / nadda
with the LG cable, wiggling, will SOMETIMES have an effect. sometimes it's solid and will only become a flaky connection after it's been charging a while already
HELP! Used "incompatible" USB cable all night, now only charges w/ computer USB port!
Okay I know this sounds crazy, but I've tried 3 cables, 2 car charges, and 2 wall charges that all worked previously... And what I've found is that I can only get my LG G2 to charge when its plugged into a computer USB port. I've got car chargers that are both 1A and 2A, as well as wall chargers with varying amperage ratings too. And they all used to charge the phone and even still do charge my Samsung S3! Also the same USB cable that won't charge the phone when plugged into a car or wall charger, WILL charge it when its plugged into a computer!!??!
And to make things even more strange, Android reports the phone as "Charging", but the percentage never goes up. And using CurrentWidget or BatteryMonitorWidget, the phone shows as "Plugged In" but shows "DIScharging" and shows the mAh utilization as draining at 18mA...
The only thing I did differently is that last night, I used the USB cable that came with my ChromeCast device to charge the phone. I plugged it into the LG USB adapter that came with the phone. I didn't realize until this morning though that a message had popped up saying the phone was "incompatible" with the the charger/cable and that I should unplug it avoid possible damage..
Did that possibly break the charging capabilities?? That seems not possible...

Unfortunately yes I have...
It's a shame you didn't see the warning message as soon as you plugged it in. Can you take it back under warranty? Sounds like it did do the damage it warned you about. The last ditch effort I would suggest is do a factory reset and see if that fixes it. If not, take it back.

Yea, I'm hoping not.. I may have to factory reset.. Boo... But I'm having trouble believing that a normal USB cable REALLY could do damage though.. I have another charger/cable combo that I keep plugged in on the wall in the kitchen and use it all the time for my S3. When I plug the G2 into that charger, it gives that same "incompatible charger" message. But what is so different about this phone that prevents it from being charged by any standard USB cable..??

I have a handful of charges at home and they all output different levels of power... though most are much less than LG G2 default charger.
Okay REALLY strange... NOW, the chargers charge my phone, but only show charge them.. Using the LG charger & cable, only slow charging is possible..
Seems my other charges are working now too.... Anyone have any thoughts?
Hi there,
I have a big problem with charging my Galaxy S4. It only charges with my notebook USB Port, my AC-adapter does not work.
In the battery menu I can see that AC is connected, when I plug my adapter in. But charging does not work with my device.
Over USB I can charge slowly. This isn't a software problem, I have done some resets and firmware changes since the problem.
Maybe my phone got a little bit wet earlier. Could this be the problem? Can I fix this with changing the USB port part of the hardware?

Having issue where S4 only charges with USB and vibrates when using AC charger
I've been having some issues with my S4. I did recently get it a little wet, but it's working fine in all cases except charging. I have my phone next to my bed charging every night. I noticed it was dead one morning, but I figured I didn't connect the charger properly. The next night I noticed it was vibrating every 5 seconds or so, but the phone had turned off due to a low battery. Very strange behavior.
I realized that it would start charging, but it would stop between 1-3 minutes. The the phone would vibrate and not charge.
I've ready MANY posts from others with the same issue and someone mentioned their phone charges over USB. Seemed odd, but I tried it and voila, my phone charged perfectly. I have many samsung cables, none of which work. It's definitely not the cable. I can plug a samsung cable into my phone connected to AC and it doesn't work. I pull the USB portion out of the AC charger and plug into a computer and it immediately and consistently charges. The battery holds its charge as expected, so it doesn't appear to be a battery issue.
I've tried the developer mode options - no luck.
I've tried bending the charging prong - no luck.
I've tried blowing out the charging port with compressed air - no luck.
I recently got an update pushed to my phone (Sprint), but I don't think it was happening right after the update. Seems like a likely software issue.
I did get my phone a little wet recently, actually it was my young children throwing water at me.
I've read so many posts and nobody seems to have a good answer for this issue. Any suggestions are appreciated.
