GNex shows as charging, but discharging.

Hi.
I know you saw a lot of post like this; however, this one is different.
When I connect my phone to charger or pc, the icon at the top shows lightning bolt sign which means its charging.
but, when i go to settings -> battery, says discharging, and of course, it doesn't charge.
since i connect to my phone to charger, counting hours on battery stops even though i disconnect it.
connecting to pc works well with usb debugging, MTP, rooting, basically everything, but doesn't charge.
I thought it is the problem on the usb port, i opened my Gnex, and replaced it to new one.
but, same thing happens. I don't know what the problem is...
what should i try now...will samsung take my phone even though i opened it?

any solution?
The same thing just happened to me. Have you found a cause and/or solution?

I just started experiencing the exact same occurrence with my galaxy nexus since this week....weird.

My phone did this. I had to replace the charge port.

Recently change chargers? Some old ones don't push enough amps to get my gnex excited. Bad cable? Any apps or mods with USB fast charge that may have gone awry? My friend had this 2 weeks and was able to fix it with a can of air and a safety pin but I know thus problem is caused by many different factors.

Battery discharging vs not charging

When my Galaxy Nexus GSM is not plugged in, the battery shows itself as "discharging". Previously this used to be "not charging". I have tried multiple (Jelly Bean) ROMs, different cables, wall and USB chargers. Same problem. The larger issue: my PC no longer recognizes my phone and I have resorted to using AirDroid to transfer files.
Can anyone shed light on this issue?
I have done full wipes, including wiping battery stats.

Mine was always discharging...
And make sure that you got fast charge off if you have that on. That disables MTP capability.

I have exactly the same problem...see my thread...its recent!

I had a similar issue, and then not long after the phone refused to charge. I had to take it to get serviced, and the ended up giving me a refurb instead.

I think it has to do with the temp of the battery, if its too hot and you have it plugged in it will say discharging.

First, don't use a charger other than the original. The different volts mess with the NFC chip and antenna. Try disabling NFC and rebooting. Leave NFC off and try to charge. If that doesn't do it I have another option that might work but I'm CDMA so you would have an extra step to change lines in file.

Thanks for the suggestions, guys. I tried disabling NFC but it had no effect. My phone is the international version (the box was in Polish) which is not warrantied through Samsung USA, so I guess I'm out of luck there as well. I'm just gonna hang in there until the next Nexus phone, I guess.

When will people realize that the difference in voltage won't cause any problems with the phone as long as they're within safe range.
I've been using the charger that came with my G2 (htc) on my nexus for months and have no problems. I would've continued using the original one that came with the nexus but it had an annoying whine to it.

Really because it sure seemed to be my problem a while back and anytime i use a different one. Guess samsung and google must not know what theyre talking about.

Chargers are rarely the problem, however different usb cables might be the problem instead.

New glitch spotted when phone is of and in the charger it wil chrage for like 2 seconds and then the animation saays the phone is full!but 2seconda later its charging again so on and so on... sort of chargingloop..
But it never charges

Am using samr original charger and cord. Works fine

I have this same issue
My Galaxy Nexus from Verizon has worked flawlessly for several months now. It updated about 4 days ago to JellyBean 4.1.1 and I have been charging the same two wall chargers, car charger, and USB cables every day since I got the phone. I even was using the USB charger to deploy and debug a simple application I am building around noon today. This evening at about 8 PM while on the wall charger I noticed the charging stopped. No lightening bolt icon, status says Discharging, and I noticed one time that it said Not Charging. Neither of the wall chargers work, nor is it recognized by the laptop using the USB cable. It is at 65% charge and is dropping fast. It seems that no one has a fix for this other than replace the phone.
Very difficult for me to believe that the USB port just went bad using the same chargers every day. Hard to blame JellyBean that has run at least 4 days with no issue even though several sites point to a possible charging issue. I even dialed *#*#4636#*#* and checked the battery status, and it's health was good. I have not rooted or placed anything on this phone that is obscure beyond my simple near "hello world" development apps. I have rebooted, and performed a battery pull with no such luck. With the number of posts pointing to a JellyBean issue, and users experiencing the same issue after the upgrade to 4.1.1 I am leaning towards this being a software issue, but it is interesting at the number of posts saying that the their only fix is a refurb phone replacement from the carrier.
Pretty odd occurrence, and extremely frustrating. As I said the phone worked fine all day today. This just started a few hours ago for me.

OK I have fixed my issue. and it does appear to have been hardware related. I will preface this with you must be very careful not to break your phone with the solution below. I read several posts about using contact cleaner on the USB port, so I looked at the port on the phone and noticed that the "toungue" inside the reciever USB port appeared to be slightly bent down. With the phone off and battery removed I used a needle to wedge under the toungue and bend it up ever so slightly making sure I would not break it. Pluged in the phone and it still did not charge. (That was last night) this morning with the phone at 55% and thinking it was going to need to go back to Verizion I did it again phone off and battery removed only this time a bit more forcefully out of desperation. I definitely moved the "toungue" up and even had a bit of difficulty getting the USB cord to slide back into the connector. But when it did the Phone is charging again. Appearantly I must of jammed the plug into the phone upside down last night when getting into my car and bent the "tongue" in the USB port. Lesson learned, and hope this helps others.

Means the battery has been recharged and discharged to the point were it holds less of the charge. Basically its an older battery, or its been tappered with with, probably a rom using to much ram or pussing the device a bit too far nightly and ported roms could be the cause I say stick to stock kernal unless you really now what to do
Scrap that wrong fourm I think

Phone only charges for 30 seconds

I just got my phone yesterday, and the Samsung charger was working fine until this afternoon when I noticed that the battery was going down even though it was plugged in. I tried different usb chords and different wall sockets, but nothing worked until I switched to my old HTC Dinc charging adapter.
However, now it will only charge for 30 seconds. It will only continue to charge if it's connected to my computer.
I have the GT-N7100 rooted with stock rom
Anyone have an idea what could be causing this?
Edit: After some more testing I found that the charge light stays on if I plug it into the wall while it's turned off. While it's turned on it still only charges for 30 seconds though. Could that mean its a software issue rather than a hardware problem?
Edit 2: I just did a factory reset and the problem is still there, so I guess I will return it for another unless someone knows how to fix this.

Try a different cable first. I've had problems with mine, so same could be yours.

Did you use the charger and cable provided with the box?
Did you root the phone yourself, or was it already rooted when you bought it.
Seeing as you've bought it yesterday, and you're new here, my beliefs are you probably bought one pre-rooted, and as such, perhaps didn't come with all the official gear.

What does 1 post have to do with newness? A lot of people don't post unless something is really bad(charging for only 30 seconds) and just read.
OP sounds like you need to Odin back to complete stock, not just factory reset from phone.

The charger that came with the box seems to be dead. When I plug something into it nothing happens. It only worked on the day I got the phone.
I got the phone from newegg and rooted it myself. I'm not new here, this is just my first post. I don't usually post unless I have something to contribute, or I have a problem I can't solve on my own.
I flashed back to complete stock firmware (no root) and then did factory reset again, but the problem is still there.
I also noticed that even though it's charging when powered off, it only charges VERY slowly. maybe about 1% every 20 mins.
I can't really think of anything else to do for it, so I'm going to see I newegg will let me exchange it.

I see the Dinc charger is an 1A charger.
I had random charging issues when I used my 1A chargers from my Mytouch 4G.
Every now and then the screen would turn on and the charging would stop. Mostly happened at work for some reason.
I bought better (i.e. higher amperage) chargers and haven't had the problem since.

Thanks, I didn't know that. That's a good idea. I'll go get a new charger and hope that works.

This is why I use a wall battery charger and just swap out the batteries. My rezound had a charging if CWM was used as recovery. I 2nd or 3rd the full wipe and return to stock and start troubleshooting.

@ChodTheWacko
Thanks a lot man. I just got a new 2.1A charger and it seems to be working fine now.

att gs3 charging slow, tried different cables too

Hi, i have my att galaxy s3, a year old, and rooted. it runs perfectly fine on illusion rom, been running that rom for a while. but all of a sudden a couple days ago it charges slow....i can leave it on the charger all night long, and it wont even be full anymore. i would say the battery is draining at a normal rate, i never really paid attention to it but i havent noticed drain issues. But charging is ridiculous, ive tried three different cables, one was a hardwired one, not usb. None of these make a difference, what can i do?

Hmm, most likely, it could your battery so I would look into a replacement from Samsung.com if you want an original Samsung made one or for a third party, these maybe:
http://www.amazon.com/warranty-Zero...UTF8&qid=1382406738&sr=8-6&keywords=zerolemon
Usually when it comes to charging, USB is my go-to but i'm assuming its pluged into the power adapter that came into the phone, right? If not, maybe look into buying a new one, maybe a 2 amp one for faster charging. Hope this helps a bit!

The other thing you can look at is if the USB port on the phone is dirty. My wife's S3 was randomly going into dock mode and not charging off of most cables. I used a small toothpick and some contact cleaner to clean it out. Remember to remove the battery and do not spray contact cleaner into the USB port. I sprayed it onto the toothpick and very carefully cleaned out the gunk. Good luck!

Got the new battery...same problem. ChRges slow. As for the charger I was using..yes it was the same one that the phone came with. I have tried a total of 4 different chargers. I just tried cleaning the contact pins with a safety pin(couldn't find a toothpick at the moment) I could t really pull out much dust but I'm gonna try charging again now.

Fast Charging No Longer Working

I wanted to share this in case anyone ever experiences the same problem. I had my Note 4 since it was released in October and didn't have any issues until roughly a week ago. All of a sudden, the phone would not fast charge. Whenever connected to the fast charging adapter, it would detect it and charge, but it would not give the fast charge notification and would charge extremely slowly (8 hours to get a full charge from near empty). In addition, my PCs would no longer be able to access it and the phone would not give the MTP option menu when connected. I tried multiple cables, outlets, fast chargers, and batteries in addition to toggling the fast charge setting, wiping the cache, and performing a factory reset - but nothing helped. I finally called verizon and they sent me a new note 4 and everything was working again.....
Three days passed and the same exact issue occurred again on the replacement phone. This makes me believe that the Samsung charger I have has somehow deteriorated and is now breaking the usb connectivity on the phone. I contacted samsung and am getting a replacement for the charger and will have to get ANOTHER replacement phone from verizon (after they finish processing my first replacement).
So if anyone has a similar issue, I would suggest getting a new charger in addition to the phone replacement so you don't have to go through the entire process again. I could be wrong that the charger caused this, but I can't think of anything else besides the recent lollipop upgrade - but everything was working for several days on lollipop for both phones.
If anyone has ideas on how to fix this, please let me know. I can't return the second phone until the first one is processed so no fast charging or PC connection until then. Thanks

Having exactly the same issues. Let me know if you work it out.

Same Issues and I have three fast chargers so it is not the charger it is the phone or the 5.0 update.
Mine was not really even charging unless I turned the phone off. I called Verizon and they are sending me a replacement phone overnight. It would not connect to the computer either. I hope this is not a result of fast charging, if so they are gonna get a lot of phone calls

I also have another fast charger which wasn't working... I was thinking that my main charger was breaking the phones USB connectivity and fast charging, but if others are having the same problem then I am wondering if it is something related to the lollipop update. I am replacing the main charger and should have another replacement note 4 come Friday. If it happens again, then I think it points to the lollipop update since both phones had this issues days after lollipop was installed.
I'll let you guys know the outcome

Had the same issue. Used a different wire. Solved the problem. Any Micro USB that can transfer data, can use fast charge. If it's a "power only" cable, or if the data pins/wires are messed up, no fast charge.

Well the problem was that all the cables were working and then stopped. When I got the replacement phone they worked and then a few days later the same thing happened again. So something was causing the connection to break completely. I am hoping that the cause was the charger which I am replacing.

Word of advice: if it stops charging normally In ANY way. THROW AWAY THE CHARGER. I made the same mistake and my Note 4 literally lit on fire melting the lower 1/2 inch of my phone and completely melting the charger. It was so hot by the time I was able to yank the cord out both the phone and charger were melted and destroyed and I ended up with three fingers with minor burns. I am lucky it did not happen when I was sleeping with my infant nearby. I now charge my phone only in the day and on a granite counter in case of fire again.
It stopped fast charging. Then I used the charger again and got a message saying "Transferring power to high powered device" then wham 2" flames
Verizon kept claiming it couldnt happen and thought I used a aftermarket charger until I brought the phone and charger to a corporate store and they prompytly replaced both the phone and charger under factory warranty.

I have three samsung original fast chargers and none of them worked plus the fact that the phone could not be connected to any computer I have makes me think it was the phone. I got the new phone today so I guess time will tell. I just can't see three chargers and cables going bad all at the same time. I also did not take the 5.0 update on the new phone.

my replacement phone stopped fast charging and computer will not recognize it now. I used a different cable that was plugged into the fast charge module from Samsung. I guess that is what caused it. They are sending another phone but for C sake if a cable is the reason this happens surely there should be a fix without replacing the phone time after time.

I finally received the new phone from Verizon and I replaced all the cables I was using to make sure this doesn't happen again. Hopefully the charger was the culprit and the problem is over and done with. Hope no one else encounters this as it really was a pain to deal with.

I got my third phone Monday and so far so good. I had a car charger from Verizon plugged into an extender that had 4 plugs in it. When I unplugged my GPS from it I noticed it was very hot. The Verizon Charger was also hot even though nothing was plugged into it. This may have been what caused my issue. It could have overheated. I replaced it with a different brand and tested to make sure it stayed cool when anything was plugged in and have used it all week without issues. The only other thing could have been the USB cable I used the evening before the second phone stopped fast charging so I do not use it either. So if you use a car charger extender check to see if it gets hot when anything is plugged in. BUT, it is scary knowing something like this can kill the USB on this phone.

I have an external Hard-drive that would constantly disconnect and reconnect with the slightest movement of the cord connected to the computer. It even caused my H/D to get corrupted twice requiring re-formatting. But all I had to do to fix it was to squeeze the big connector on the cord a little and tighten it up. Just a thought.

It's been a week since I received my third phone and everything is working perfectly. I can only assume the charger was breaking it and I'm glad the issue is behind me.
So for anyone experiencing this, I suggest contacting Samsung to replace the charger before going to your cell provider to replace the phone

I'm having the same exact problem. My 2nd replacement phone is now doing the same thing as the first one. I have too many scenarios now though and I'm confused as to which it is. I have two Adaptive chargers.. Batteries, phone, or chargers...

As soon as I replaced the charger, I didn't have this issue again. I suggest sending your chargers back to Samsung (or whatever other brand you have) because one of them is breaking the phones

I would place my bet on a bad cable. With the higher voltages that fast charge uses going through the danger of arching and sparking is increased especially if there's a poor connection would fry or weld melt metal inside the connector. This could damage the USB port in the phone and cause the phone's USB port to have a bad connection. This bad USB port in the phone could fry the other cables as well leaving you wondering why everything went bad all at once

My phone will fast charge on my two vehicle chargers (at 1.5 amps and 2.1 amps), but refuses to change any faster than 500 mA on two separate fast charger bricks. The same bricks work fine for fast charging other phones, so it's my phone, not the charging hardware. I'm using the same cable(s) for all instances, which leads me to believe that something is wrong with how the phone interprets the "smart charging" signal on the bricks, or that the phone is sending the wrong charging signal.
I can still connect to a computer just fine, so my issue may be different.
Does anyone else have the issue with bricks but not with chargers without "smart charging" capabilities?
I've had this problem on stock 5.1.1, Jasmine rom 6.0.1, and now CM13. I full wiped everything when reinstalling, so either it's hardware, or an issue propigated through many roms. I've tried a few different kernels too, just to see if that was the problem.
I'm changing the battery tomorrow to check that possibility. Maybe I'll bend the contact a slight bit and see what happens (phone catches on fire)...

Hi guys
I have the same problem as you ,so what I have to do to solve this issue without replace the phone,
I have rooted 5.1.1 stock rom, If i flash full stock rom 5.1.1 does this help or what?

Turns out one out of the three new cables I bought didn't work, and my OEM cable didn't work for fast charging. Swapping for a good cable fixed the issue.
