Hi
I have weird battery issue with my new GN.
when the phone is ON and connected to AC power the phone isn't charging (display in buttery menu "Not Charging").
if I turn my phone off then its charging without any problem.
Is someone suffer from same issue?
TNX
wow. no I don't have this problem and I haven't heard of this before.
Have you tried connecting it to other chargers besides the OEM ?
Yep.
Tried OEM Motorola Atrix Charger and through usb. same issue =\
Check if you have fastcharge on

Fastcharge is off
Should I turn it on? (Im using AOKP)
By the way, if I do reboot while my phone connected to AC power, its being charging successfully after the process is finished.
(sry about my english )

You could see if turning it on helps, but it isn't necessary to charge the phone since its a hack. If you do turn fc on, remember you will have to turn it off if/when you plug your phone up to a comp to transfer files.

Yes, I've seen this multiple times on my Sprint Gnex. Seems to happen mainly when I'm running AndChat with poor signal. If I don't pay attention to it it seems that it'll start charging again. Haven't bothered checkin into it that much but my suspicion is that it may be getting too hot.

Guys, I had this happen to my phone within a week of owning it (a week after release). I almost returned it, but fixed the issue myself. the issue is with the charging terminals touching in the USB/Charging port. Get a flashlight and shine it directly into the port. You'll see the outer part of port is metal, and in the center is a 'tongue' that is also metal, these are the 'terminals'. In my case the tongue was very slightly touching the outer terminal - probably due to the times i carelessly shoved the charger into the port (sometimes upside down). This essentially bent the tongue downwards, and when the two terminals are in contact, the charging circuit is short circuited. I fixed this by taking a pin (though anything flat/thin could work) and pressed the tongue in the opposite direction. This centered the tongue, and by being careful when plugging in my charger, it's never happened since.

freaked out last nite when the same thing happened to me - thanks this solved it!
A few days ago, my Nexus stopped charging while turned on.
I noticed that it still charged when the phone was off. So, I started turning it off @ night to charge it.
Well now... for some reason when I plug the phone in while it's off, it shows me the charging animation (the battery filling up), but then all of a sudden it shows a battery with a bolt running through it (im assuming this means fully charged) and then it does the animation again.
Wtf is happening??
thanks guys.

It sounds like the 'Ghost charging' issue. See if the small pin in the Micro USB port is touching something. Look very carefully! If so, try to bend that pin slightly up just so it doesn't touch the surrounding.
If that doesn't help. Buy a replacement port for like 6 USD. Replacing it will take you at most 15 minutes including re-assembly.
Some people reported problems with using LED controller apps like light flow and flashlight apps, try uninstalling any that you may have and see if the problem is resolved, if not then what the guy above suggested seems to be the only solution

I had something like that before ... my mobile shows it is charging while not plugged in, sometimes it wakes up and sleeps many times repeatedly as if I'm plugging but and unplugging it again ... finally I found people talking about the problem and the solution was using the original cable for charging ... if not solved yet you can do what I did, clean the micro USB port using a small brush and the last thing you can do if not solved , you can left up the micro USB pin using a thing clip, and that's what solved the problem for me ..

I did a restore so there shouldn't be any apps keeping it from charging now.

only bend it up if you can see it touches the surrounding. Bend it up with the smallest thing you can find that fits in there. BE CAREFULL! do not use force. You need to use little power to lift it up. I myself never had this issue but I did read alot posts related to this. And lifting the horizontal pin up solved it for most of the people that sufferd from this issue.
One question: Did you ever use any charger except for the standard Galaxy Nexus charger? (Including car chargers and such)

no. never. If I mess up, will replacing the charging port resolve the issue?
Bending the pin up resolve the issue for me. The problem returns back after a charge and unplug perhaps pushing the pin back into wrong position. I uninstalled lightflow app, it had no effect.
I have ordered the replacement usb port, middle cover(the usb socket seems worn out). I will post an update

I think I have the same problem. I tried bending the pin, removing LED apps, various combinations of unplugging, turning off etc., and I tried changing the USB PCB in the phone to no avail. I even tried different batteries. I have absolutely no clue what the issue is. This is doing my nut in.

If you have rooted your phone.. wiping battery stats in recovery mode did the trick for me.. It happened to me atleast 2-3 times.. It's not a permanent solution but just a temporary measure..Im not sure what goes on. I've only had my Gnexus for 1 month and its happened like 3 times. Really3 sucks. Anyone know if it is software related? perhaps unrooting would do the trick??
It could also be a hardware problem, it's been reported before. Following is a guide to replace the USB and charging logic board on a Galaxy Nexus (the guide is for the CDMA version, but it's very similar to a GSM version): iFixit Guide You can order the parts for the GSM version here: Replacement part.
I just ordered one because my phone keeps doing the same stupid things: sometimes it charges, sometimes it doesn't, USB connection is completely erratic and it strangely enough always shows the loading icon when it's off and connected, but doesn't actually charge the battery. Tried wiping, reflashing, restoring, switching on and off, wiggling the cable, taking another cable, readjusting the position of the USB pins - to no avail. Now I'm trying replacing the board. Wish me luck!

My Nexus is also having the same problem. Bending the USB pins does the trick but it keep coming back.
Last night I had the same charging problem, so, I applied the same trick, but this time, it created a different problem. When I plugged the phone into my computer, it can be charged but is not recognized by Windows. Also, the headphone plug is acting funny. When a headphone is plugged, it is not detected and music still coming from the speaker. All these happened after I bent the USB pins, might be I applied too much force or might be the pins give up itself this time.
Anyhow, just order a replacement part and hope it will resolve all these problems.
I have fixed the mystery headphone problem, It was caused by the Wechat app that I have recently installed. Once I have unistalled that app, the headphone works properly.
Just waiting for the new charging port USB flex cable to resovled the "USB Deivce Not Recognized" problem.
I have a small question. Can I turn off the display backlight when the charger is connected ?How? That would be great temporary solution
I have read in other forums from people that have replaced the USB port with no results.
What I read and worked for me was to lift the small "tongue" inside the USB port towards the screen. As soon as I did it the charging animation disappear. This, of course, is most probably just a temporary fix and the problem will come back eventually. But at least it's stopped driving me crazy for a moment.
I tried plugging the charger and it charges normally, but it looks like the charger pushes the tongue back down so the "charging when not charging" problem re appeared. I pushed the tongue back up and "fixed" it again.
With this in mind one would think that changing the port would fix the problems but people have reported the opposite :/
BTW, I am using the original charger, although, I have used many other chargers with this phone
Hi,
I had the same problem of ghost charging, it started with phone not charging when connected to charger and then randomly showing charging...
Now discovered it causes vbus_tuna_otg wake lock in Bette battery stats and high system usage in setting> battery, basically not letting the phone go to deep sleep, causing battery drain.
Any way to fix this. ?

I don't know how to go about this, because, to my knowledge, its not effecting the phone in any way. Maybe a little drain, but that could be 4.2's problem. But regardless, my phone is always "on charge" no matter where I am. On any ROM this happens, so I know its a physical thing. I've been told that you can use a knife to push the contact up a little, but that only works until I plug it back in the next day. So...... Any thoughts on how to fix this without replacing the charging port? (To my knowledge, that involves soldering very small parts.)

Well if it worked by bending the contacts up but goes back when you plug it in. Have you tried a different cable? Also have you cleaned out your charging port?

Agreed. At this point you could be having issues where you can't see it, such as where the port is connected to the board.
Had to take port completely off before i noticed... Sprayed with acid (not recommended) and cleaned it, rinsed it, soldered back in place = good to go..... For now

If you need to repair it go the this site. http://mobiletechvideos.mybigcommerce.com/samsung-epic-4g-touch-usb-port-repair/
You send it to them and they will fix it.
Turn around time is normally 5 to 7 days.
I mean. I guess i'll use it until it breaks. And even then, I use an external battery charger. So. Yeah....
Yeah i fixed mine.... I always end up fixing all my electronic problems... But i lost my charger so i still use a battery wall charger... Used my brothers charger to test my fix

Hi jeep, i have a similar problem but i'm not sure it's the same, i happened a few days ago when myi changed the battery and pugged in the charger, i noticed there was something strange, the phone's screen showed the battery was charging before i pugged in back (just when i placed the new battery). Now it behaves as it's always plugged in charging just when placing the battery in, the phones is turned off and the screen shows charging battery icon (i've tried 2 more batteries), and also there's no usb connection to the PC either.
It's a very bothering problem, the phons won't go into deep sleep, and the screen goes to the screensaver all the time (as it where pugged in charging)...
I always repair my own electronics, months ago i replaced the power button, do you think it could be a bootloader issue or just the micro-usb port?; when you fixed yours, do you think i should take it completely off and resolder?
Any advice will be really appreciated!!
Thanks

Okay, this is a weird one that I researched and researched on the web. I think the problem is somehow related to the USB port. It would seem that my handset thinks it is always charging. I should qualify that statement by saying that with the handset unplugged from the charger and checking the SETTINGS > BATTERY stats it says "0 seconds on the battery" presumably meaning that the handset thinks it has a freshly charged battery and no time has expired since removal of the charger. However, it knows it isn't charging because it also says "89% Not charging". The other weird thing is the handset doesn't screen timeout when unplugged from the charger. That is, I have to hit the lock button to turn the screen off otherwise the 15 second delay doesn't work. I've also checked the developer settings to verify it isn't set to force the screen to stay on. However, the 15 second screen timeout delay works perfectly when the handset is plugged into the charger. After 15 seconds the screen shuts off and the red LED charging light comes on. Lastly, with the handset sitting idle with the screen black if I receive a phone call or text message but just leave the handset sitting there the screen lights up but it never times out after 15 seconds.
Any ideas if this is a USB port problem. I know it sounds like a firmware problem but I've checked just about everything you can think of. I've gone as far as to root my phone, backup all my stuff, then re-flash JellyBean. Speaking of USB port. Has anyone changed one out on a S2 Epic Touch 4G? I know that other S2's have a USB flex cable assembly but I can't seem to find one for this particular handset.

I had tried the toothpick trick that you and others had recommended. In fact it did make a positive difference but I still noticed there were still some strange things going on. I went back a second time but this time with a sewing needle and some magnifier glasses and picked it clean of lint and other junk. Of course with was done with the battery uninstalled. I think I'm back and up and running. We'll see if any of the problems come back. Thanks!

My aunt has a device with the exact same problem. It goes doo-doop like you connected the charger. And you can't turn it off ever because it gets on again. Did you fix it?

Using the toothpick/needle trick went a long way towards getting it to behave properly. Like you said, it was doing the "do-doop" thing intermittently and sometimes it would go into and out of charging mode so fast that unless you were astute you wouldn't have realized that what it did. To figure it out I went into SETTING > BATTERY and observed that the "discharge time" on the battery would typically stay at 3 seconds which told me the phone thought it had been plug into the charger.
For the last two days it would seem that I have fixed the problem. After you carefully clean out the USB port of lint and junk with a toothpick and a magnifying glass or readers you may also want to consider getting a can of compressed air to blast it clean. I'm talking about the kind of compressed air sold at Walmart or Office Depot that is used to clean electronic equipment to blast the dust away.
Let us know if you get it fixed!
I don't know if cleaning the USB port had an effect on battery time but I'm getting relatively awesome battery performance like I've never seen before. After 12 hours and very light use the cell phone still has 81% battery left on it. It used to be sitting at around 30% by this time in the day.
think im having this problem. thinking its a damaged usb port. old battery everytime you stick the battery in or plug it in it thinks its charging. new battery i just ordered does the same too. its still charging so ill see what happens after but i say charging port probably?

I went through the same exact thing...ordered a new battery thinking the original battery was at the end of its life and causing the phone to behave strangely. With the new battery in place the craziness continued. I was thinking the micro USB was damaged and needed to be replace which BTW isn't an easy thing to change out like some of the other Galaxy phones because the S2 uses surface mount solder connections. You'll need very good eyesight and professional soldier skills to do it right without effing it up. Luckily, doing an extensive cleaning of the USB port fixed the problem. You wouldn't think lint would be conductive enough to cause a problem but alas, it does. Use a toothpick and compressed computer cleaner air with the battery removed when you clean it.
I'll have to try with the toothpick later. It's weird when you go into setting and look at battery it knows when it's on charge and when not on charge. But soon as you put a battery in, it turns on by its self but to the charging screen and can't be turned on unless both charger and battery are in.
Will the battery percentage read accurate still I wonder?

Yup, that is exactly what I saw when I was having the problem. Basically what that screen shot is telling me is 13 seconds ago your cell phone made the "doo-doop" sound as a temporary short within the USB port fooled the cell phone into thinking it had the charger plugged in but just as fast as it thought the charger was plugged in the temporary short went away. In fact the "short" may have come and gone so fast as make it so that "doo-doop" isn't even heard. The key here in recognizing the problem is that while your charge may have been unplugged for hours you'll note the number of seconds that have gone by since the cell phone thought it was charging will be somewhere well under 60 seconds or at least that is what I experienced. I have every confidence that you have the same exact problem and you just need to thoroughly clean that USB port of every speck of lint and dust. Also, make sure your charger USB is clean and lastly make sure none of the pins on the USB connectors is bent and that that middle portion on the cell phone USB is right in the middle and not bent up or down in any fashion.

I'm in the same boat now [emoji22] Just happened a couple nights ago... Phone is plugged in but not charging. Not that big a deal, as I just got some spare batteries and external chargers. But now I've got to be super-cautious when flashing stuff, as I can't just Odin back without working USB

That's what I'm stuck doing now. I'm not gonna be switching roms anymore lol. Had to buy a universal charger for the battery
I had this issue with mine as well. At first it seemed to be the recovery but I reverted to stock unroot and it still happened sometimes shine blue to make it think it was completely charged I know this phone had a lot of hardware issues. And then I took it apart cleaned it and what not. It still happened. So after some time it just stop happening and functioned normally. I am unsure what the problem was or why it happened. The whole time I really couldn't charge my phone at all unless it was by computer only
is there anyone with problems charging the t320?
it goes fine until 40%, above that or stops charging or is really slow, like 1% in one hour.
i thought it was a rom issue, so i flashed the original rom from sammobile
the charging at this moment is 56%, 150mA average, when isn't negative - 200
this is stock usb and charger, and also with other charger/cable is the same
Me too

I was just searching the forums as bought mine yesterday and have a similar problem, mine got to 56% then stopped charging. If i turn off the tablet it does start to charge again so will fully charge with it powered down and see what happens.
soon i'll be testing another charger
you can see the charging voltage on the galaxy charging current available on playstore
most likely i will use warranty

@tidy01
Pop the back off gently and disconnect the battery from the main board. When you reconnect it, let it charge up fully before turning it back on. After this, it will behave normally for the rest of time.
Thanks

Thanks for the reply but it seems my issue was caused by a faulty outlet socket. The socket works fine for everything else but would only charge the tablet when it was powered down. Tried charging off my laptop and desktop usb and it was the same, but tried some other outlet sockets and they charge fine. I understand the usb outlets might not provide enough to charge the tablet but hadn't considered the socket as I know it works, must be just enough high resistance to prevent it charging a working tablet but provides enough current to charge it when it's powered down. The fact it was showing a 56% charge was just co-incidence.
Thought it might be worth posting this as it's not something I've come across before.

Thought it might be worth posting this as it's not something I've come across before.

Here's the thing. When mine was misbehaving I could get it to start charging again by switching outlets or even reversing polarity on the wall plug. It was a temporary fix as within days the problem would be back. I thought I had it fixed so many times. It always came back. If it happens to you again just remember the above post. It's been four months since I did it and never once has it been quirky. Something in the hardware needed reset that only disconnecting the battery could do.

Thanks once again, I will keep this in mind if does happen again.

Pop the back off gently and disconnect the battery from the main board. When you reconnect it, let it charge up fully before turning it back on. After this, it will behave normally for the rest of time.

Hi, I have this problem also, as well as random reboots. I just want to ask you on how to take the back off of the Tab Pro 8.4?
Cheers

Very gently use something like a guitar pick or a credit card to pry it up around the edges

Thanks for your reply. Would you pry the back faux leather cover from the back, or from the front via the glass screen (like in note 10.1 2014)?
I wouldn't want to break my tab he he thanks

It's the faux leather thing you pry off. Keep the angle that you pull on the cover shallow and work it slowly.

with no other solution i did too pop the back off gently and disconnect the battery from the main board, now it's working OK, let's see how long
cabel pull
hoping this works. I just filled out a warranty email today for same issue on 12.2 Tab Pro. It pried the case open with a credit card. Very slow, took about 7 minutes. Pulling the power cable in the middle, probably behind green tape. Use needle nose pliers or something small behind the wires and pull up. The pins are tiny and will f*ck the whole thing up if bent.
I get the feeling that the screen turns itself on even when eye tracking settings are off or closed in case. I hear the annoying sound at night when charging. Why Sammy does not have a smart current sensor built in is insane. Asking you to unplug when most people will leave on and charge overnight. Just dumb.
I can't get past 57% charging for last 2 weeks. Stock, unrooted for first time in a long time, so I am pissed to hear ROM had not effect. This is likely undocumented hardware issue Sammy doesn't want to admit to.
even on my T325 I had the same problem but I solved it this way ...
I have worn the battery completely until turn off my device, I loaded the battery overnight to device OFF.
wipe and install rom custom samsung
I launched and used app "battery calibraton" (root)
I have now done 4 cycles of charging to 1600/1750 mA

There is no need for physical interventions on the hardware, maybe someone does not know in depth the behavior of lithium ions

Perhaps not, but I and MANY others have encountered the same problem. Across multiple Roms, fully discharging and recharging, running the so called calibration apps. Rebooting, unpluggin, replugging. The problem NEVER fully went away. It would work for a charge cycle or two or three, then would reappear.
I finally took the back off, unplugged and replugged the connector., closed up the case, charged it for several hours before turning it back on.
Not ONCE has the problem occurred since that intervention. That was over a month ago.
Maybe it's not lithium ion behavior, it might be in the charging circuit and hardware.
If you have a suggestion, then by all means share it so others can solve their problem.

I've already written how I solved the problem, but in 5 years and dozens of Android rom installed on various devices, this problem for me was very frequent.
Always the same. On my ST325 I solved like other times in the past.
No news I found on this battery, battery charger of the same problems since I know Android

sorry for my bad English ...
for this device I've tried all the roms available (CM11 or not)
the problem is very acute especially after CM11> Pro Plus V2, but the problems had already occurred some time with the various installations buil CM11
about a week I did the operation described above (already done in the past even on my previous samsung device, Note 1, Galaxy s4, Galaxy Mega, Galaxy tab 3 g3 ) with the same result ...
The battery charges very quickly with the device ON to 1700 mA (monitored with "Monitor battery widgwt pro")
again sorry for my english
