[Q] Slow Charge with Including USB3.0 Charger

So this is an update to a previous issue I had...
When I first got this phone, the included USB3.0 charger charged much faster than a standard microUSB charger. But then it stopped charging fast. It pretty much stopped charging at all really. Like maybe 1% battery added in like 20 minutes.
So I sent it into Samsung and they returned it saying they couldn't replace it because the wall adapter part was actually from a Note 2 which doesn't support the 3.0 wire (even though it was absolutely the one that came in the box). Once I got it back, I found a brand new set of the same wire and adapter (it was covered with the packing plastic wrap and all that stuff which is what makes me think it was actually a replacement). I plugged in my phone and it charged quick again for about a day. Then it went back to charging slow again.
I still need to get down to T-Mobile to see if they'll exchange the wall adapter which supposedly doesn't work with the USB3.0 cable even though both times it worked at first. It's their mistake but I have a hard time believing they'll own up to it... The model on the adapter by the way is EP-TA10JWE with an output of 5.3V 2.0A.
Assuming they don't exchange it... What do you guys think are my options here? I ordered a 3rd party USB3.0 cable from Amazon and that does the same super slow charging as this (and it didn't come with a different wall adapter anyway so it was kind of a stupid purchase on my part). I tried plugging the cable into a computer with USB3.0 and it didn't make a difference. Is there a different wall adapter that is known to work with the fast charging on this phone that I can buy? Is it AT ALL possible that the connector on my phone is the problem and I need a new phone? That would be terrible, but if it's something I need to do I will. It charges just fine and the same speed as any other phone when I use a microUSB cord and adapter like the one that came with my old S3.
Any thoughts?
Thanks

That's weird brother. I checked my charger and i have the same model number and mine charges extremely fast. Maybe it's a problem with the device it's self.

no not rooted (i was thinking about it and then this whole thing started)

I've noticed the same thing with mine ..and definently trickling on USB 2 .. I thought USB 3 was suppose to be all the hype about how it would do when u turn fast charge on in a rooted phone with custom kernel.. The charging is slower than my note 2 on USB 2..

its so weird that it DID charge faster for that first couple days (and again after I got the new one)... And I have 2 friends with Note 3's that say they charge faster than their previous phones (one of them had a Note 2).
I just don't know what to do...

The enhanced speed with USB 3.0 is for data transfer, not charging. Using a USB 2.0 or 3.0 will charge your phone at the same speed.

Well first of all, every review says it charges faster with the included 3.0 charger... So I don't see how you could be right about that... Not trying to argue, it's just that was one of the features that everyone talked about... And second of all, the 3.0 charger that came with it barely charges at all anyway anymore, so even if that was true, either the cable, adapter, or phone still has a problem... Phone charges fine, maybe 3 hours for 100% charge with a microUSB cable... About 1% in 10 minutes (that's as long as I can bring myself to bother testing the 3.0 charger for). And that's if the screens off. If the screen is on it actually just won't charge at all, it's like it drains quicker than it's charging with the screen on with that 3.0 cable... Again I say "cable" but it could be the cable or the adapter or the phone that's the problem... I'd love to find a way to figure out which it is...

For some reason the 3.0 charger charged lightening fast today ... Maybe the jedi ROM had to settle in for a few days maybe?

[Q] Nexus 7 won’t charge

Hi I bought my Nexus 7 2013 used in February. It came with a 3rd party charger and usb cable. It’s worked fine since I got it and it use to charge fine. I would use different usb cables and they would all work. Within the past 2 weeks or so it has become increasingly hard to charge it. Also this started happening on the stock 4.4.4 rom with root enabled. Today I installed a custom chroma 5.1.1 rom just to see if anything changed but it’s the same result it doesn't charge. The chroma rom says it has the Franco Kernel. Not really sure what that means but the stock rom's kernal wasn't changed.
I've left it off and connected charging to the AC for hours and would turn it on and it would have not raised at all in battery charge percentage. When it’s on and I can better see the percentage in this battery app I have installed I noticed if I jiggle the cable at all it will disconnect and connect again. So it might not be making good contact. It does this with every usb cable I have tried on it. However when I don’t move it and have it charging in sleep mode it does see it as connected and it says charging in the battery monitor widget app when I wake it, but it doesn't charge stays at the same percentage or lowers.
There is sometimes where I get lucky and it starts charging but it’s becoming increasingly tougher to get that to happen. I haven’t had any luck since last night messing around with it with different cables. I've even tried charging it on my PC but it’s the same result. It says charging but it doesn't charge. However if I do connect it to the PC I can view the files on the Nexus 7 fine as long as I don’t move the Nexus 7 much. I've also tried the AC adapter on my phone to see if it works and it works fine and charges. I've tried a kindle fire 9w charger on the Nexus 7 and that doesn't charge either.
Any idea what’s the problem? If I buy the official AC charger do you think it would work? Am I better off buying a Qi wifi charger? I rather not waste money on the AC charger if there is a good possibility of it not working.

Hi,
I seem to have the same problem recently. I am running on 20150519 CM12.1 nightly right now but this problem started to occur about 2 weeks ago i.e. with an older nightly version running...
It really feels like the USB connector is broken. I have to move it the same way headphones jack has to be moved when it is broken. Have you tried more different chargers? I did but no solution.... Now I got it luckily charged to 90% and I am making a quick backup.
Do you have still warranty? I technically do but would need to get back to stock and lock the bootloader back.
I found threads on how to get back to stock via USB connection but is it possible to lock the bootloader without being able to connect USB to computer?

No unfortunately I have no warranty since its a used item. I tried the 3rd party cheap charger, amazon kindle fire charger and my phone charger on it they all don't charge. I think you can replace the USB board on it but that would require opening it up and doing the repairs yourself. I think I will just get a Qi charger and see if that works. I kinda don't want to spend money on that just to find out its my battery that doesn't work. I am not sure what the problem is since I can connect the nexus 7 to my PC and it will see it and its files fine. So I know the USB port works at least a little bit.

It's a sub-board (usb-sim-touch module) issue. I would reccommend using a wireless charger as a quick fix since the wireless charger module is located on the motherboard itself so you should be good.
I may have a few sub-boards for the 2013 lying around but i'm not sure if they're 100% okay - as in calibrated, tested and fully functional. Also, i'd need to know if yours has LTE or not.

I have a Nexus 7 2013 32gb wifi edition. Thanks for the info. I put in an order for one of those wireless chargers.

perhaps you did that already, but from experience i must say that in 9 out of 10 cases it's the cable and 8 out of 10 cables are mediocre as compared to how it could be. no why i say that ist because i tested something between 50 and 60 cables during the last 2 years because i had similar issues and bought a special ampere and voltmeter with with the correct usb ports to measure the flow, same device, same power source, thus as empiric as possible result most cables charged between 0.9 and 1.1 A while about 10% were half of that and only few charged at 1.5A while 3 charged at between 1.9 and 2.1A. understand me right, same device, same charger, sam place all same condition, in car, on motorbike, on wall plugs. only significant difference were the cables. so check those first before taking more costly path which then only remain workarounds.
BTW amongst the bad ones were many that came out of the box with the devices and from different oems but many samsung original cables.
what i did i painted the ends of each cable with red for bad, yellow for ok, green for good and the outstanding ones already had a color, it were the stock cables from the oneplus one which had the best charging rate. good luck

My phone is not fast charging

Last weekend my phone was working perfect then the battery reached 1% i put it to charge and i saw that it was charging but it said 6 hours to charge, which i found strange, i tried multiple chargers, etc. and none of them worked, so i thought that maybe the usb port got damaged because the same thing happened to my old note 4 and i fixed it replacing the usb port but i changed the usb port and it didn't work, so i thought that maybe the replacement was broken too, and i order 2 more from different places, and they didn't work. So I think that maybe is a software issue, I have the OF8 room rooted with AOU Kernel and TWRP and using the engineering sboot but there is no way for me to flash to stock because the phone is not being recognized by the computer as a usb device, so when i connect it to the computer is only working for cable charging. What do you guys think? Maybe i got all the replacement port broken, or maybe the sboot is affecting the port, or worst case scenario, the mainboard is faulty (which i don't think so, because the wifi, bluetooth, gps, screen rotation, everything else works)

Computer USB ports generally cannot fast charge unless it's USB 3.0. The phone doesn't need to be recognized by the OS. Fast charging is different from quick charge, where you will need to buy a compatible charger.

Thank you for replying back. But the issue is not the fast charging with the USB computer, is with any kind of fast charge/quick charge wall adapter. I think that i found the issue, and it was an external battery pack that it was damaging usb ports, because i got a brand new LG G4 and after i connected it to the battery it started to behave in the same way, so looks like the usb port gets broken every time i connect a device to that external battery.

Need Help About Charging My Phone

Hi everyone! My phone is having a problem. It was fine until today.
My phone charge EXTREMELY SLOW and decrease battery percentage sometimes. Then I used Battery Monitor Widget to check my phone and what I saw was terrible!!! The energy go into the phone was only <100 mA, while it was >200mA on my friend's Zenfone 4. Then I tested on a new battery, it still had that problem
And now, I'm wondering about this: Is my phone's charging port cause this problem???

I suppose that a bad port may be possible. How old are both batteries though? Even if you just got one, keep in mind many S3 batteries have been on the shelf for a long time. I've had 2 in the past that were bad even though they were brand new.

Try getting a 2amp charger. and a fast USB charger from ebay.

It is probably a bad port. I know the port on my phone is bad, i have to wiggle it to get it to start charging sometimes and sometimes I have to wiggle it to get it to charge faster. If it is the port, you can either try to solder a new one on, they are $5 on amazon, or pay someone to do it which can be very expensive. Or you could go with a wireless charging solution.

It's often not the port like many people think. I have several cables that will only charge if there is pressure on one side or you set it down with the cable being pulled a certain direction. Other cables work perfectly fine though. These micro USB cables go bad in this way all the time. So always be sure it's not the cable before trying to mess with the port itself.

G4 Charge/USB port issues

I've had my G4 since almost launch day and within weeks the supplied USB cable stopped charging the phone. I thought it was a cable problem, but it worked fine with other devices.
I tried other cables with the G4 and these still charged it so I thought nothing more of it until charging degraded with every USB cable I own to where the phone would only charge 20-30% during an overnight charge and the phone would frequently not recognise it was plugged in at all. I contacted LG who did a repair under warranty and all was fine.
I've now had the repaired phone back for about 3 weeks and the same problems are starting up again and it's only a matter of time until I am forced to return again for a repair.
Is anyone else having similar problems? I thought I may have just had an unlucky manufacturing problem, and the LG reps confirmed that to repair my phone they basically replace all the internal circuit boards and components rather than just replacing the individual component that is faulty (in this case the USB/charging port)

Basic debugging includes asking stupid questions, so please forgive but still answer any of those
Are you using a different charger? If so, check if that one is within specifications and if you do send in for repair again, use a different charger.
Are you propping up the device at an odd/weird angle or in a dock of some sort with the cable attached?
(As they replaced the entire print, it's probably not this, just the USB-micro port bent or broken.)
You could double check the wall outlets being used, there might be some kind of electrical problem there.
Either using all kinds of fancy electical testing gadgets, or stick a USB light into the hub or charger, does it flicker?
When sending it back for repairs, did they check the stock charger as well?
Hopefully these questions help you find any logical or plausible cause.

Hi FreezyExp,
1. I am using the standard charger that came with the phone, but this has not been repaired/replaced. I have tried other chargers too, but all the same issue.
2. No weird propping up or anything like that. If I hold my phone while it is plugged in it is constantly vibrating as the charger connects and disconnects, and if I place it on the desk to charge I have to ensure that I have at least 3-4" of cabe "on the desk" to give it enough support to make the connection.
3. Wall connection is fine and I have tried it with a range of outlets around the home, both with extension sockets used and plugged directly into the wall and there is no different. No flickering light when using a USB light either.
4. When I sent it back all they asked me to return was the main section of the handset - so no battery or rear cover, no cables or chargers etc
It does seem to be the same issue as last time, a USB connection becoming loose from the main motherboard, but it seems weird that I have had the same issue twice in the space of 4-5 months.

I've been having some sort of problem with my G4 usb port. If I plug it in to a computer, it will lose connection and get a connection again if I barely touch the end of the cord at the phone end. I've tried many different cords and different usb ports on my computer, but it still has problems.
I can't fast charge, either. When I plug it in to fast charge, it actually starts discharging even faster. I've had some extreme battery life problems, too. It drained from 100-36 the other night with everything disabled, and it's been doing that kind of thing a lot lately. I'm guessing that the charging port is what's messing up my battery life because it won't charge correctly.
Never dropped it or anything.

I got my G4 on January 24 and my USB port has also failed. I am getting a replacement from Verizon, but am concerned that a six month old phone has this issue.

I also own a G4 H815. A while ago the phone started not receiving any charge from the cable and I would have to prop it up from right under the cable's micro usb end. Thought it was because it was bent inside the port and not making connection with the cable so I had the port replaced. Now I'm experiencing the same problem and I think it might be the cable that's already gone kaput and is effing up the port itself. I took the phone to the same place to get the port replaced again and bought new cables (I lost both the original adapter and the cable, which were charging slow anyway. Now using a 2A Asus adapter which works great) and when I asked the guy at the repair shop, he says it's a chronic issue with G4 devices. I don't really understand how it would happen twice in just a few months even with a new charger port. What should I make of this? Did they replace my port with an already faulty one, cahrged me full price and now trying to sell this bogus or am I really doomed with this phone?
