S4 will not charge with AC charger; only USB

Last night I was charging my S4 in my car adapter, but noticed the cattery was still going down. I went home and plugged it into my AC (wall charger) and went to bed. The next morning the S4 was dead and couldn't charge. The only solution was to plug it in my computer and went an hour for it to get some charge back.
I have a root i337m running rootbox 4.1, and I went into TWRP to wiped the phone and installed the ROM again - no luck.
Is this a battery issue, a software issue or a whole device issue? Thanks.

I don't think its a rom issue. I tried charging via USB as well and had phone charging a few hours and it ate crap. So I only charge via AC outlet only. USB charges but at a very slow pace.

I made an error in the OP - I meant to say I left it to charge on the wall and I got nothing.
Right now, the charge light doesn't even come on if I plug it with AC.

Maybe see the results by changing the charger you're using?

I've tried 3-4 different chargers and cables, same issue. Charges slowly through PC,doesn't charge at all with AC. Did a factory reset after reverting to stock FW, no luck.

I doubt it's a ROM issue, but there's no harm in reverting back to stock to see the results (assuming you've backed it up). If it all fails, i think you should unroot and send it to Samsung for the warranty. Software problems are somewhat easier to fix here than hardware, so it may be the best option to let Samsung handle it.

I had similar problems with my Note 2 before and now with my S4. What I found was, sometimes the usb cable wasn't tightly plugged into the wall charger. Once I've made sure of this, I've been able to charge (AC) every time.

I found this article that indicates that the S4 is looking for special sauce on the D+D- pins.
http://www.anandtech.com/show/6914/samsung-galaxy-s-4-review/2
Obviously the Galaxy S 4 will charge with any USB charger, but the charge time will simply be longer. Samsung uses a voltage divider and signals the presence of their own charger by sending 1.2-1.3 V across the D+ / D- pins, this is similar to what Apple does with 2.0 or 2.8 V across the pins for various USB chargers they've shipped over the years. This signaling is essentially Samsung's proprietary tablet charging signaling which they've employed on the Galaxy Note 2 and now SGS4, in fact the two use the same exact charger, so it's worth tossing out your old ones and getting the appropriate one to take advantage of the faster charging.
However I do not believe this to be 100% true. I think not all chargers will work..
I took a charger that is very vanilla (Wall charger but the D+D- pins are NC) and it works with the S3 and NEXUS7 but does not work with the S4.
This charger uses a stock USB cable so I took a wall charger that had gone bad but had a dedicated cable and hacked off the end and wired up my own cable...
That works! So it appears that the S4 will only charge properly with certain chargers that do something to the D+D- pins (either shorting them with a resistor like the article indicates
I then took a look at the cable I used to replace. It is a Motorola cable and it has the ID pin pulled high built into the cable... So I suspect that is required for the phone to work... But to fast charge it will need the special sauce indicated above!

Had the same issue and found the solutions which worked for me. Go into the developer mode and deactivate the usb debug mode.

Had the exact same issue. I took a soldering iron to my charging port on my phone. Problem solved. The ID pin had a bad joint.

I have a strange issue, my s4 is detected by pc, charges normally with usb ( wall or pc charge ) my battery is full but when I take the cable from microUSB port and s4 should work with the battery, turns off and consumes no battery, it's like refusing to use the battery and that it is full! battery checked on a sph l 720
I've tried installing other roms with safestrap but I still have the same problem, refuses to consume battery and while the battery is at 100% ,my s4 shows 0% if I disconnect the usb cable... game over. However, I can be on the safestrap menu for hours only with the battery, no problem, is a problem of rom I think but did not know how to fix it .. : (

I'm having the same issue as the original poster. The USB port is good, charges fine when connected to PC (although much slower because of different mVS). Have tried amidst everything and nothing fixes it. I've turned debugging mode off and back on, restore to backup, complete wipe and reinstall of 2 ROMs with and without apps, fix permissions, different kernels, different USB cables... The adaptor is in good condition. But when plugged in while on my phone doesn't recognize that's it's connected. Previously out would give a false charging reading. If off sometimes I got the grey bar battery but note is just vibrating every few seconds. Idk what to do...

I'd guess it's the charger. Get a new one

I had the same problem. S4 will recognize charger as USB charger, not AC. solution was to clean usb port connector, was some cloth covering wires. then restarted and worked ok

I am having trouble charging the phone the same way. I have reset the phone 3 times and still can't get a charge.

Charging problems - only charging over USB

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?

Yes, I tried another cable but had no success

I dunno if I can ask it here, but i don't charge over usb, i mean it just "hold" the power level for me. Is that normal ?
Is your AC outlet working ?

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.

Charger not working properly

Lately I've been having issues with my phone and charging. It started with the stock OEM charger getting steadily harder and harder to use.. so I bought an Aukey charger to replace it with and it completely refuses to work on my phone, so I tried another phone and tablet and it works great. I tried my super old Galaxy note 2 charger with a motorola usb cable from my maxx and it works fine... I then tried that usb cable on the aukey QC 2.0 charger and it won't work... tried the same cable again on my phone with the sammy charger and it worked... tried a QC 3.0 aukey wall charger and it won't work... yet I have a QC 2.0 incipio car charger. it was working with the USB moto cable I've had in my car since I got my Bionic... then it just stopped charging my phone, got a new USB and it works great now except the moto usb will work for friends, just not my phone.
I have absolutely no idea what's causing this... I thought maybe there was lint in the charging port so I took a tootpick and cleaned it out, got a small piece of lint, same thing with all the chargers. I can't find anything online, and being a tinkerer I've tried everything I can think of before asking. I'm starting to think the phone itself is having problems and the port is actually bad or there's something wrong in the software causing it to have problems with turbo or QC chargers.
any ideas?

There is a general inconsistency with this device and Quick Chargers... if you look in the Accessories area there are several threads discussing it.
Personally, I use the Aukey QC 2.0 charger for travel with an Eversame premium braided cable and it works fine, yet others use the same combination and it won't Turbo charge or in some cases charge at all.

I also face the same issue. Some USB cables work with my Moto X Style and some doesn't .

i am having an even worse issue and i am sure its a software problem, recently my moto x stopped charging using the moto charger so in the last two months i have 4 different chargers who worked for some time each now it just doesnt work at all, i have cleaned the port numerous times then it just stopped working so when the phone finally died all of a sudden it started charging but as soon as it switched to turbo mode the charge would stop and start over again. i have deduced its a software problem as once the phone tries to go to turbo charging mode it cant sustain the charge and cancels it. amphere even shows its discharging while on the charger , however if it starts charging while the phone is off with a low voltage adapter and turn on the phone once you dont remove the cable it will charge (extremely slowly but it will charge).

FYI... There is no software problem with charging, if there was it would affecting hundreds of thousands of people. And I doubt you have 2 software problems, a bad kernel and a bad bootloader/recovery image, because 2 different things control charging when powered on and powered off.
Issue here is you likely have a high resistance connection somewhere between the USB port and the battery itself, or a bad charging circuit... It's hardware.

while i can understand where you are coming from when the phone is in factory mode (motorola customer care told me to try) its charging fine also turbo charging is working now just it doesnt recognize the sim card. it was a suggestion from Motorola customer service desk, as i live outside of the us they gave me some options to try. they said it was a software glitch where the phone may have gotten an overload from a bad connection and caused the phone to not recognize the charger. however while the phone is off this check is not performed which is why i was getting a lower amp charger to work as the phone did not have to enable the protocol that allows for quick charge/turbo charge voltages.

My stock charger discharges the phone

Hello,
I just got my lg g6 and when i charge up the phone with the stock charger i encounter an issue.
The phone recognize the quick charge and all but instead of charging up the battery lose percentages and never really charge up.
The cable is correctly inserted both to the charger and to the phone, if i use a non quick charge charger everything works fine so the cable shouldn't be the issue.
In addition, the phone from time to time behaves like the charging disconnects and reconnects. The screen turns on and i see the message "charging" which immediately turn to "quick charging" like if i just inserted the cable, but the battery keeps being drained or just stays at the same %.
I also noticed a very strange battery graph. i'd post a picture but i can't upload images or put links at the moment.
in the time period that it was charging with the stock charger the graph presents a series of blank colums that interrupts the graph and the segmented line is trending downward.
I thought that maybe could be a faulty charger, but i tried it on other phones ( htc one and a lg g3 non qc capable) and it charges them totally fine. So now i really have no idea what could be wrong.
I have stock firmware, no root and locked bootloader.
Any ideas?

Download ampere from play store and see if it really charge
Inviato dal mio LG-H870 utilizzando Tapatalk

I already checked and it shows as charging.
The speed is turbo as well.
Ampere shows a charging value goes from 40mA to peaks of 1200-1300mA (very rare and immediately drop afterward)
I just tested and did a 30 minute charge session, it started at 54% and finished at 53%...
Monday arrives a new quick charge 3.0 charger. If that works i guess i'll blame the stock charger. Otherwise i could think of replacing the phone...

Most of the time this is due to the USB type C connector (both ends) getting dirty/dusty. I just dusted it out with compressed air and it worked fine again. A friend with a Aalaxy A5 (2017) also had this exact problem. Give that a shot and let us know.

I had a spare can of compressed air. Dusted both the usb-c on the cable and the phone and the standard usb male and female on the cable and charger. Waited for any condensation to go away, plugged it in and charged for another 10 minutes but still nothing.
The phone and charger are 4 days old and i bought them from amazon so no egdy e bay sellers. I find it hard i could be something like dust or anything. Anyway now all connectors are squeaky clean but the problem persists.
Frequent disconnections ( i get the bottom text "current connected" even if the cable is still in ) and the battery refuses to go up even 1%.
The strangest thing is that on normal charge with my old g3 it works fine, could it be that quick charge and normal charge are on different circuits? Maybe just the QC one is faulty.
Or even some component manages it with the standard 5v current but when it ramps up to 9 with the QC it gives up.
Sadly i know too little of this stuff to actually come up with a plausible explanation

I would return it as doa.

Ughh i'm gonna wait tomorrow and test with another charger.
I would really hate having to set the whole phone up again from scratch...

If by any chance you have to replace the G6, make a backup with LG Back up on you SD card. When you get the new phone you restore the backup and you 95% done.

The charger arrived and everything works now.
I was just unlucky thay i got a faulty stock charger.
Might do some test with the cable as well just to check if it works properly.
Thank you for all the replies!

Charging slowly message

So I have a strange problem. A few days ago I discovered the phone was charging so slowly and on the lock screen a text appeared: "Charging slowly". It's equivalent to USB charging with a PC or notebook. However I use wall charger the same as before, from October 2017. Ok, I thought the charger has some failures, tried an other one. Same.. "Charging slowly" (I used this second charger before and it worked well..) Then I changed the cable. Same message (I also used this cable so 100% it's not defective).
I tried 3 roms. Refleashed the stock, RR and AEx. Tried different kernels: void, mint, franco. Nothing has changed.
May it be a hardware-related issue?
Thank you

Hi did you managed to find a fix?
I am having the same issue - lock screen a text appeared: "Charging slowly". Switched few cables still having same problem. I am convinced is not cable or charger issue.

Your wall charger is most likely the problem, even official can fail, you need a powerful aftermarket to test, it could be the cable but most likely the charger no providing enough power.
No A1 but android, see here: https://android.stackexchange.com/q...d-phone-charging-slowly-how-to-make-it-faster

I use either samsungs ep-ta20ewe or lg's mcs- h04er charging between 1600-2000 mA in accubattery pro.

I've switched few cables and 2A chargers. All getting the same "Charging slowly message"

The reason why most of you are charging so slow is because most likely, your phones are warm
As soon as the battery reaches 38°c, charging begins to slow down and will continue to be slow unless you cool the phone down

The battery temp is ok. 34°C

Solution: USB module replacement
I got back my A1 about two weeks ago. The service replaced the USB module at the bottom of the phone and now it works. I used a Tronsmart QC2 charger before. Since it's been repaired I use the stock charger. I was a bit curious and tried a few days ago with the Tronsmart. Same message: "charging slowly".
I think my Tronsmart charger is deffective and now I avoid using it..
Sum up, the repair shop diagnosed the problem. The phone became deffective but they are not sure why. The USB module replace turned it good again but with the Tronsmart charger it still doesn't work. I have to use the stock charger.
(also works with other chargers from my old Samsung phones). Interesting.
(they changed the USB module under warranty, but otherwise it costs in Hungary 10 000 HUF (~31 EUR, ~36 USD).
(refer to my thread opening post, before the USB replacement, the charging with the stock one was as slow as with other chargers, ~200mah, after replacement it's ~1800mah again)

The same solution as in my case. Nice to hear it fixed this annoying issue.

I was running into the same problem, but after 2 months of replacement I got the message of charging slowly again. Been trying to change the adapter and cable but still not working, til I got the idea to use my mac's charger and it works. I don't know why, anyone's having this issue?

Install Ampere from the Play store and check the speed. It should be ~1400mha.

Having the same issue but i found a tricky solution
I am currently running dotOS and earlier I was on Pixel Experience...on the lock screen i used to get this message along with the current and the voltage readings (mA and V) so all I did was I tried to remove and put the cable back in the phone and everytime the values changed a bit....doing this 3-4 times gave me the reading around (1700-2000) mA and 3(.9-4.1)V and the message said charging...and sometimes it said charging rapidly....and if it didn't work out then I flipped the cable( like I was putting the USB in the wrong direction).....WORKS EVERY TIME
