I have this problem with my note, the screen keeps saying 'battery disconnected' when charging. After a while it continues to charge, and then it says that again, every 3-4 minutes.
When the charger is disconnected, the phone works fine.
I'm very sure there are no loose connections, as I opened it and pushed everything in place and it fits nicely.
Is it an android issue?
Clean the usb socket on the phone. I used a toothbrush and it fixed the problem for me.

I've found that the USB micro cables I've been using have been "wearing" out... Replace with a new one and try again...

I should clarify the title by saying that trying to charge this phone is resulting in a number of odd results.
So firstly, I've tried using the wall-mounted AC charger. I then tried using USB on my computer, in 3 different usb ports. The phone was charging perfectly less than 24 hours before this problem began.
I plugged it in as per usual, and it didn't show the little lightning bolt on the batter icon like it should. It wasn't registering that it was plugged in. I tried plugging it into my PC, and it wasn't showing that it was connected via USB. In addition to that, my computer was failing to install the drivers for it. I went back to the AC charger, and tried a few different outlets, including one on a power strip. Nothing worked.
I searched online, and found that other people had this problem, and could only fix it by resetting to factory default settings. One person even had to do it twice to get it to work. So I did this, and it still didn't work. I tried charging my old phone with this Ac charger and cable, and it wouldn't work either. So I thought it must be a fault in the cable. So I dug up the cable (also micro-usb) for my old phone, and tried it. It worked just fine for my old phone, but my S4 still had the same problem, but with something new. It would say "Dock connected" but still not charge.
As of right now, it seems to be charging properly with my new AC mount and old usb cable, but I'm worried that this could happen again. Considering this seems to be a problem for other people too, what should I do about it? Is there some way to prevent this sort of thing from happening? Was it purely the other cable, given the fact that it didn't work with my old phone either? I'm on an extremely tight budget, and this phone is my only way of being contacted for job interviews, so having it in working order is very important. Any advice would be very appreciated!
Having exactly the same problem... couldn't find over the internet a solution yet or a position about it...
Affraid it's a hardware issue and have to send to the assistance...
Anyone know what to do?
Yup having the same issues - but i noticed only having charging issues when battery reaches 20% or the low battery notification pops up
it detects that a usb is connected but it wont charge
Solutions:
- dont let it go below 20 which is ****
- some people claim that if you use a 5pin charger instead of the 4pin which samsung includes solves the prob
Mine is a little more serious I think... haven't found a solution like that yet.
I have to connect/disconnect multiple times and it suddenly works.
But between those connects/disconnects it presents multiple problems, it appears on notification bar "Dock Connected", sometimes appears "Dock Connected" and on the notification bar appears "Suggested Apps (Anchoring)", other times it appears "Dock Connected" and the volume bar appears on the screen and stay there freeze (the phone works, but the bar doesn't disappear)... Sometimes the phone starts charging and suddenly stops, other times it says it's charging and if I remove the charger it keeps the charging symbol on the battery icon...
It's completely crazy, gonna take to service I guess.
Have you tried blowing out the usb connector on the phone with a can of compressed air?
If there is a minute piece of dust there it may be shorting something out - error that dock is connected. I know this happens to other phones, there was a big thread about it on the S3 forum. Might be a simple little thing like that...
Unfortunately that doesn't work for me, will send to service, let's see.
have you solved this problem and how?????

Yep, chalk up one more with the same problem!
At first I thought it had something to do with Aviate, a custom launcher from Yahoo (actually a pretty sweet one at that!)
But I guess not.
My work-around is to reboot the phone while connected. It charges fine while turned off and seems to keep charging when booting while plugged in.
Still... this is a stupid work-around and I want this fixed properly.
Any news from any of you guys?

Had this problem today. Suddenly out of nowhere "Dock is connected" message appeared after plugging the charger in and out. Tried to clean out the dock with stick and cotton on the edge. Then turned off and plugged in charger. Problem exists. Phone charges but stops regularly. It is very annoying when you dont know how to fix this kind of problem.
Any new solutions?
Right after this post, I froze the app "battery doctor 4.9.2" using Titanium Backup Pro (you can just uninstall it i guess). Then just plugged charger and now it's already Almost 90% without any interruption.

Amazing! I've dealing with this problem for weeks and internet didn't give me any good answer, but the whole problem was a baterry monitor apk that for some reason was interfiering with the charger. Thank you so much!
I had this problem too and in my case it was a hardware problem. When i start the charging it kept repeating the start proces of charging with the vibration and the grey battery icon(in case the phone was turned off). The battery icon with the green charging light just didn't showed up. I tried many things but nothing helped. I let the phone keep charging for the whole night but in the morning i saw that it didn't charged anyway!
Then i went to a local phone reparation shop(none official samsung) and they knew immediately recognized the problem and it was the usb/charging connector where you plug it in the phone. They fixed it in 1 hour for a cheap price and from then(i think a few months ago) it charges back perfectly. It seems it's a disease with S4's.
In my previous post I was happy thinking that all this charging problems were solved after uninstalling battery apk. But, in fact, my S4 charges very slowly after that incident. I have tried two other samsung adapters (galaxy s4 mini; grand prime). First one results the same (up to 5 hours charging), the latter was comparably shorter (up to 3 hours), but still slower than it used to be (2 hours normally). So I highly suspected the hardware might be the reason. Thank you for your information, now I will also have the phone checked at some local repair shop. And give feedback of course.

You probably got some water damage in your port. What you need to do is clean it. I used pure alcohol and a toothbrush for that. After that I flashed a custom kernel so I could enable fast charge true usb.
That's the reason your phone is charging slowly, it thinks it's connected true usb. So you need to boost the usb charging. After a few charge cycles I could revert back to my standard kernel and the problem was fixed.
I think ur right Lenny.
Mine S4 got wet last weekend and now i am also getting the " Dock is connected" message when i plug in the charger cable.
I can charge my phone but sometimes while charging i hear the sound go off and on what you hear when unplugging the charger.
I will try your solution and hope it will fix mine too. Thanks for posting ur tip!
I suggest you go buy a new genuine cable for an s4, the s4 does actually require a special cable capable of 2A charge rate otherwise you can end up in all sorts of bother.
Thank you all for sharing tips. I cleaned the port as suggested, then replaced my cable. Now everything is back to normal.

Same problem - galaxy s6
Hi there - same problem, on my 128gb s6. started this morning. Yesterday everything fine, would charge when connected via USB to both laptop and to regular samsung usb power unit. Have now tried 3 different USB cables including the samsung cable, 3 different usb power units and of course tried all 3 cables in laptop usb port. Have checked phone's usb port - clean as a whistle. Have rebooted both connected and unconnected. Started getting 'dock connected' message, now it just wont charge, although starts up fine. I take very good care of the phone, so no water damage or untoward shock damage (never get it wet, never drop it). Remaining battery charge seems to fluctuate between 30% and 40+ %, depending upon whether it's plugged in or not. If I turn it off, then connect usb cable, the phone just reboots, still not charging. I then turn it off and see no green battery charging screen, as I used to seen when connected but turned off. Should I just hard reset and take to repair shop? Still under warranty.
I would return the phone for a warranty repair. Software would not usually prevent the phone from charging when powered off.
As a final test, see if the s6 will charge wirelessly, assuming you have access to a qi charging pad and the s6 has a built-in qi receiver like the North American version of the s6.
My nexus 7 recently started to behave weirdly, it doesnt charge while turned on, neither with USB or AC. It does charge perfectly well when turned off.
I am unable to use the USB either no device is detected, nor in normal mode, USB debugging, fastboot or adb.
Please help me to get this USB brick fixed on my Nexus 7 asap.
Please help developers!

I've had this problem for a few weeks now and have yet to find a solution.
I'm quite astonished I haven't found a fix for this either. I have yet to open mine up ... I'm try to get the bootloader relocked, so I can warranty the dumb thing. But since it's not recognized by USB when powered on, I can't.
Have you tried putting pressure on the cable when it's plugged in? Also are you using the factory cable?
Sent from my Nexus 7(2012) that has zero issues.

Unfortunately it is a hardware failure. Most likely the USB port assembly. It is possible there is a loose ribbon cable connection.
Nexus 7 not charging
I have the same problem. My Nexus 7 will not charge when turned on. It will not now connect to my pc. I have checked the drivers and all are ok.
It happened a few days ago Its rooted. I can restore backups that are on my Nexus through rom manager, but still the same problem. I thought of doing a factory reset, but if it will still not connect to my pc. I will loose the data. If it is a hardware usb port failure, what is the next stop
I know this is going to sound strange but open up the back of the Nexus and you will find your battery... And you will notice that it's loose you have to plug or wedge it back on to the battery clip it comes loose overtime use a credit card or similar to open the case :thumbup: success

Has anybody else had the same problem, if so, how did you overcome it.
Similar thing happened to me... No amount of pressure or angling of the charging port would work. Batteries ran dead as a result. Sent it to the service center and they would assess it for 2-3 days and try to repair since it is under warranty. I'm gonna get an official dock to try and save the charging port from the stress of always being in use although I know that's not the only factor at play.

That's sounds a good idea with the official dock for charging, but you should not have to do that.
To much usage of the micro usb port is going to give problems. I'm always connected to my pc, downloading roms ect. but as I said before, my N7 charges perfectly when not turned on.

As I can't connect my N7 to my pc. Is there anyway to revert to stock. Need to return for repair. USB port not working as it should.

I think the only answer is a faulty USB connection.
I tried to change mine and finished up snapping the connectors. :crying:
Now have one useless N7
Long story short: plugged the n7 into the car's OEM stereo USB port on a long trip and it registered as a device with the stereo and let me play some music off of it, when I woke up a couple hours later it wouldn't charge.
After a short bit of troubleshooting, I found that OTG devices were still working but it would only charge if I shut it right down - if I start it charging while it's turned off and leave the charger attached while powering it up it's not detected by the software so it never says it's charging, but does still charge - though if at any point I pull the charger from either the n7 or it's supply I have to shut it right down again to get it to charge. Unfortunately, the same can't be said of a PC USB device connection (aside from the charging part of course.)
After a couple weeks using it like this, I got my hands on a multimeter (my stuff is all packed in storage indefinitely or I'd have been replying to this topic sooner) and confirmed that I never register anything beyond a few millivolts on the detect/sense pin (which I find very odd as it's supposed to have a pull-up) with nothing attached to the usb port, and that aside from a short time in fasboot that unless the n7 is powered right off it's trying to supply 5V to the USB connector. I attempted to use the faux123 kernel that has options to disable this power to allow host+charging (and my hope was to slow the battery rundown to make it more usable even if I have to shut it off to charge it), but the n7 appears to ignore this and still powers the USB connector.
In this case it most definitely is NOT the IO/USB/headphone assembly inside the unit. At the moment I'm operating on the theory that Asus skimped on protection circuitry in the charge circuit as in my mind this type of damage should never occur when it's properly designed, and I'm presuming the motherboard dead with regards to being a USB device - too bad my warranty is likely up, though I can't check that as it was a gift and all the paperwork is buried in storage. Thankfully it's still capable of fast charging when off, though this doesn't leave me very happy as this also effectively takes away most recovery options if fastboot is the only thing left working.
If I manage to source a replacement mobo I will work on doing a post-mortem and seeing if it's down to a faulty component (I've seen this sort of behaviour before, a pulled up line not getting pulled up, when a filtering capacitor decides to go flakey.) More likely though I'll either sell it, give it away or put it on the junk pile with the rest of the Asus products I've had to retire in the last month due to their questionable customer support (the other products were due to Asus deciding they were "legacy products" and not updating drivers for windows 8/8.1 despite only being 5 years old.)

Very Interesting
I am sure you are right, but I'm not qualified to agree or disagree.
I have had quite a few Asus products in the past and never had any problems.
My Nexus 7 (2012) was also charging properly. I only have the issue that it only charge when turned off AFTER I charged it:
(1) using car charger; and
(2) charge it using official charger but inside a train using train's power plug
So it seems that these devices really need a normal wall-charging paired with official charger.. otherwise, something bad might happen..
Has anyone tried to use Wireless Charger? does it work?
Hello All,
I've had my razr m for a bit now, unlocked bootloader, and was running a CM 10.1 release on it for a while. I wiped it, and installed CM 10.2 nightly (10-2 build i think) - i knew i had to potential to blow up my phone. Was using the for almost 2 weeks, then I went back to my parents house and had my phone hooked up to i guess what was a cheap china wall wart with the microusb cable already built in. it got kind of hot then turned off, i unplugged my phone from the wall and put it on the floor in the garage. i tried to turn it on a couple hours later, no dice. now when i hook it up to anything (only using legit chargers and a PC that can be sacrificed) the led just stays on green, but the phone doesn't even turn on...
any advice?
tl;dr
i hooked my phone up to a cheap china wall wart after upgrading the rom and using the rom for 2 weeks.
now the phone doesn't turn on.
thanks
IMO it sounds like the battery or the charging circuit is fried... normally when the led stays on and green its telling you that the battery is completely dead and will remain that way until the charge level reaches 4-5% then it will boot to the charging screen... I would plug it into a Motorola wall charger for a half hour to an hour if after that time the phone still won't power on I'd pick get a factory cable/adaptor if that brought it to fast boot I'd flash stock and attempt to charge again...if it wouldn't charge i would find a battery somewhere...

Hmmm.... can you get into fast boot mode with the factory cable you made?I'm guessing you found the walk through on how to make them did you make it correct solder points solid and getting +5v off pin 4...when plunged in (to charger) do you get a response from holding volume down and power....

nope, doesn't even seem to turn on.... i have a 100% new battery on the way, i am going to try to replace it, there is a chance the other battery i had hanging out was bad. I also am making a new factory cable using the microB plug from sparkFun. as a note i might have my friend make a new case for the phone for me that has a removable back.

so i got all the goodies in and hooked up the factory cable to my phone, no love from windows (ie doesn't detect the phone)
any ideas?
i know the cable is good, i have another phone that i have check it with.
i also have a board from my old xt907 (which i broke by throwing), and when i connect the factory cable to it, windows seems to think its there.
so the board for the phone that was hooked to the cheap china charger i think is 100% dead... when i hook it up to my machine with the factory cable nothing shows up.
the other board that i have has some qualcomm usb serial port show up....
any ideas on what i can try for the dead board to try to bring it to life? there is still some data i want of the damned thing....
My battery was dead so i wanted to charge it.
But i can't get it to charge anymore and show the charge logo or anything on the display.
I tried normal power button
power button + up or down control key
I had it plugged in now for 5 hours...
Any ideas what it could be?
Sure it ain't your charger? Did you try using different chargers?
Try turning the phone off, then plugging in different chargers while it's off to see if the charging display pops up.

The problem is, i don't have the original charger anymore.
Today i tried with the htc charger and a normal usb-cable with iphone adapter.
Both didn't work.
I additionally tried charging on computer (usb) or direct power source.
I will try another charger.

If you have access to a wireless charger, try that. If i remember correctly, it activates a different charging circuit that can help revive a phone when plugging it in won't.
I unfortunately don't have a wireless-Charger
Yesterday i tried with the Nexus 5 Charger. Didn't work either.
The smartphone doesn't even get warmer. So I think it does nothing...
Maybe try to clear the usb port better?
Habe a lookat the USB port, i Gad the case once, that one oft the 4 contacts oft the port peeled off and wasnt able to connect anything. I was able to put it back in its Position using some time and steady Hands and a microscope
Second, for some people it helps to completely disconnect and reconnect the battery.

n try to see manually if your battery is showing a voltage change while charging..
hit thanks if this helps u
Update
Wireless Charging isn't a solution for me.
But!
The Phone did some weird things yesterday.
I plugged it in for several hours.
After one hour, the notification led blinked red a couple of times, then the screen came up with the symbol that it is charging.
Then it went black again.
Unfotunately nothing more possible.
The back was getting warm, so i think the battery was definitely charging.
Any ideas?
