[Q] Galaxy S4 won't charge

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.

[Q] Wireless Charging on/off pulsing at night

Hello again friends!
On my phone, see sig for details, I have noticed whenever I place the phone on my QI Pad, while it does charge, The 'power source' is reported as AC, instead of Wireless. I believe this to be the cause of my problem of at night, when full charge is reached it chimes to confirm full, then drops 1%, so chimes to start again, and repeats.
I tried holding my QI Receiver (After market) to the terminals on my friends S3 I9300 and it showed up as charging Wirelessly, Can anybody tell me what in my phone tells the ROM what the power source is ?
And If they know a fix for what im experiencing. for example, if this is kernel related, any recommended kernels that support 4.3 ? c:
Thanks heaps in advance

I'm using the stock Samsung charger with a third party QI receiver module in my S4. It's correctly identified as a wireless charger when connected, but the problem with intermittent charging at night that you describe still appear. I believe this problem is inherent to the technology. However, I "solved" it by deleting the charger connection sound as well as using Tasker to completely dim the screen at night. This way I'm no longer bothered.

I can turn off the vibrate and sound nd screen on in settings, But I wanted it to identify correctly so I can use Tasker, and Daydream, only when on wireless.. :c
Im thinking it may be Rom specific.. in which case Ill ask my good old friend i've never really had direct contact with Vertigo

Display keeps turning on while charging

Hi does anyone else have an issue while charging the phone where the display keeps turning on every 10 seconds and then turns itself off?
Bill

No. It sounds like a third party app is causing that.
To check, boot into safe mode and try again.

That happens with one of my wireless chargers. I guess when hits 100% then drops and back to 100% Not sure if your using wireless or not.

I was not on a wireless charger, on the other hand I was on my old HTC changer that I have on another room. Was not doing it from what I noticed with the Samsung charger.
*** tried a different HTC charger and it seems to have stopped turning on, wonder if that HTC charger is throwing out different power

Or maybe it's got a short in it. My car charger was doing this on and off this morning. And I can tell the wires going into the base are going bad.

Yes I have this issue! I just bought this phone a week ago. I've been using the fast charger included with it. Every time I charge with the fast charger, no matter if the phone is on or off, the display will turn on and off every 10 seconds or so like it keeps getting disconnected/reconnected from charging. I tried charging my phone with a regular phone charger and the display no longer turns on and off. What's going on?

Yes, been having this issue as well (happened before I rooted). Only happens when I use my old HTC chargers, doesn't happen with the included Samsung fast charger, or a 3rd party wireless charger. Have tried turning off fast charging in Settings, disabling the Stay Awake when charging option, and charging in Safe Mode - makes no difference. Would be great to know what causes it!

Yes I'm having same issue! Only when I use my old HTC charger! Any other one it doesn't do this! Would love to know a resolution!

Its the older chargers, like the HTC, not having sufficient current for the S7s bigger battery.

Probable solution
I had the same issue with my S7. A week after buying it the display kept lighting up randomly during charging. I switched chargers to an older Huawei and the issue went away. Last week the issue came back. I tried blocking apps but it did not work. What worked for me was clearing the USB cache. Settings > Apps > Show system apps > Enabled > Search for USBsettings > Storage > Clear data and cache. PS - This also works if the phone wont charge due to moisture detection.

I had the same issue with my Samsung S7 Edge while charging using one of my dual monitor's USB Port. I just switched to another USB Port and it stopped doing it.

Weshp, thanks for your very specific answer. It seemed like it was working (my phone stayed off for a longer pause), but after about a minute, it started coming on and off again and when I check, there's data in the USBsettings again. If you have any other ideas, I'd love to know.

My Galaxy S7 has been doing this on and off for a long time. I suspect the cause is overheating because the battery is charging too fast. The lower power chargers won't charge as fast so they won't heat up the battery. If I'm wrong, I'd sure like to know how to fix it.
I can't find the path to clearing the cache so I haven't tried that.

Fast Wireless Charging Works but regular Fast Charging does not.

Like mentioned in the title, my fast wireless charging works, and when I put my phone on the pad it tells me it is fast wireless charging. However, whenever I try to use the cable directly and not wireless charging, it becomes cable charging which is incredibly slow (8-10 hours for 50%).
I have obviously checked all the simple steps. I'm using the adaptive charger, I'm using a good cable, fast charging is turned on in settings. I even tried factory reseting my phone but still no luck.
Is it possible that my charging port is loose? And if so is there any way to fix this?
The other possibility I'm thinking of is that my Europe to America convertor might be bad (I have the international version so I have to use the plug convertor) I recently lost the one that came in the box so I had to buy a new one off amazon. Are there such good things as good and bad convertors or are they all the same. And if it is the convertor, why would the wireless charging work but the cable charging not.
EDIT: I just checked plugging in an S6 to the cable and it says fast charging. Does that mean it is definitely the port on my phone?

May sound odd but have you tried unplugging and replugging the charger in over and over to see if one of those times it pops up as fast charging?
i had this problem with my Note 5 (im in the UK and note 5 was not released here so i had to buy a Russian variant and they sent with 2pin to 3pin adapter)
I don't think i ever had a fix for this other than using a different fast charger without the adapter..
However like you The official note 5 charger with adapter does work to charge my s7e fine though
so our problems seem pretty similar... Maybe buy a new fast charger that doesn't require an adapter and try that?

Phone stops charging after Oreo Update. (On my second phone right now)

First of all I'm very sorry for posting on a developer Forum, I had lurked here for about a month looking for an answer and I can't find it. I wouldn't had made an account otherwise.
Here's my problem, my phone randomly stops charging (not notice neither) since the Oreo Update. I believe is because of the update because I return my old phone and bought a second phone and decided to leave it on Nougat, I decided to update it to Oreo because I missed notification badges and the day after I already had the same problem.
Things of Notice:
*Both phones where new and on the latest security patch.
*My phone does charge overnight when in wall socket but will stop charging when I used the USB on my car (my car has a USB adapter but if I charge it there, it will keep READING USB and repeating the cycle)
*Phone also stops charging when I use an extended battery. (I'm an avid Pokemon Go Player)
*Restating the phone a couple of times, fixes the issue.
Is there anything that I can do? everything else about the phone works perfectly (Facebook takes a long time to load but that's it). If there's an answer already please forward me to that post. Thanks again

Could it be because the update enabled quick charge, so now the phone requires a bigger energy output from the USB?

Does changing the cable help? If not, try doing a factory reset.

Since this is my first phone with USB type C I only have the one cable. I had notice the battery backup is charging so it seems like a problem with the car charger but I need to test it first. What charging output do I need to charge a modern phone like this?

Anywhere from 0.5A (laptop USB port) to 2.5A (tablet charger) should work. Can you test charging from a computer?

I'm sorry I answer this late, I was unable to log into the site from my phone. (forgot the pasword). I did some testing in the weekend and it did charge on my laptop, it charge extremely slow., Just 3% in like an hour. (with constant use).
I kept using it with my power bank it kept charging reliably as well as in my house. But it keeps having the some problem at the car, So here's what I'm wondering. If I use one of those 3.0 USB car chargers will it charge my phone? without a problem to my car? I don't know if this phone supports fast charging (the specs says yes but I never seen the fast charging message with the regular charging)

No worries. Yes, laptop charging is slow.
I'm not sure if the stock ROM supports fast charging but custom ones do, and it can't harm your device. I don't see why it would harm your car if it was made for it. Maybe your car's USB port broke.

I have had the same reaction on one of my phones after updating to oreo.
Changing the charger from a 1A model to a 2,4A model solved the issue.
