This guide will help you:
- diagnose charging problems;- fix problems with the touchscreen while charging;I decided to write this because I searched for my problems on-line and never found a complete answer, just partial undocumented answers, essentially guesses from people, tried them, most didn't work, wasted a lot of time with trials so I hope this will save some people some time.
1. My phone says it's charging but the battery level drops or stays the same.
This is common when you are not using the original charger, but in order to check if you phone is actually charging you need to look in dmesg for something like this:
Code:
ab8500-charger ab8500-charger.0: VBUS input current limit set to[B] 500 mA[/B]
When connected to a computer (USB 2.0 port), you will usually see a limit of 500mA, and when connected to a car/ac charger, you will usually see a limit of 1500mA. If the charger is defective or not recognized by the phone you will see 0mA, even if the phone will look like it's charging it's actually not charging!
2. I get touch screen errors when my phone is connected to a PC or when charging.
It took me a while to figure this out, but it's quite simple, you need to check that your outlet is grounded. Once you plug your notebook/laptop/computer/charger into a grounded outlet all problems will go away. If you can't get a grounded outlet but still need to use your phone while plugged into your notebook/laptop remove the charger from the notebook/laptop and all will be fine.
The touch screen problems can also be fixed some times by using another charger, but this is a process of trial and error, for example I managed to get 2 chargers to work from 10.
thanks man... great post.... already clicked thanks button....

Does anyone know what might cause this? Is it a problem with my USB port? I noticed it with my home and my work wall chargers.
Before I call Verizon (whom it has been reported is out of Rezounds, and I'm unlocked/rooted), I was hoping for some advice.
Thanks.
An update -- now after I unplug it from an actual PC, sometimes the USB/Charge and USB Debugging symbols remain in the Notifications bar. Could that mean the pins on my actual microUSB port are defective? I've now tested with a 2.1A wall unit too, and every charger I've tried has been a new USB cord.
Oh and just to rule out software I tried in Safe Mode too, no help. Anyone have an idea aside from calling up Verizon (which I will do after my long weekend out of town)?
I've developed the same issue on both of mine I've had. My solution was to simply run a kernel with a Force AC Charge option built in. Have to be careful, however, as the option may cause excessive heating of the battery if you do any intense usage under charging status (playing a game, trying to run GPS navigation, etc.) It rarely poses an issue, but just a heads-up.
You should never use your phone while charging it alwYs turn it off and set it down. When you are charging ylur phone resistors and capacitors are heatingbup your phone now if you are on it talking on it basicly you are heating up the whole board and if it gets hit enough it will losen the solder from the joint and may cause a chip creep effect on the board causi ng varios problems that are very hard to troubleshoot

Try a different USB cable. I've had cables that would charge only, no data. Drove me nuts, I thought it was HTC drivers. Swapped cables fixed it.
The charger is presenting itself in a way that looks like USB. This is very common because iDevices will not charge at all unless the charger does this, so if a manufacturer wants to support iPhones/iPads, they make the charger in this way. Unfortunately, Android devices limit themselves to 500mA when the charger is made like this. Yes, many kernels have fast charge options that make the phone ignore this, but my advice is to get a charger made specifically for Android. Use the one that came in your HTC box as a wall charger if you can. Get the Verizon branded car charger...it charges Android devices correctly.
Yeah, there are many chargers that leave the USB contacts active. Thing is, I've had an HTC branded one that used to show AC at first turn USB on me... Everything else shows USB too unless I force AC in the kernel. Seems like some other condition, degradation or something.
Thanks for the responses so far. I have tried three different wall chargers, each with a different USB cable. Other phones show AC but not mine. At the moment, plugged into the HTC wall wart, I am being asked of I want "charge only" or "disk drive".
Could this be a software related issue? It was mentioned that some ROMS have a force - AC but I am on the newest non Global RUU, unlocked S On, and rooted with TWRP as recovery.
Bump -- is there any chance the RUU and then unlocking and putting TWRP on could cause this issue? Verizon is trying to get me to run a factory reset to "fix it".
Ugh.
Hi guys I hope you can help.
I AM OFFERING A REWARD OF £10 GBP TO THE FIRST PERSON WHO SUCCESSFULLY ADVISES OF THE RIGHT FIX FOR THIS ISSUE *.
There, now I have your attention - brace yourself, this one’s a tough one.
About 2 months ago, I flashed DeltaROM 4.2.2 V2.2. I’m a serial flasher so I’m quite aware of what I’m doing. I had some issues with it that I tried to get support from them but they unfortunately didn't get back to/couldn't help me.
The original post is here in case you’re interested, the biggest issue being my S3 no longer charges correctly. If I plug a charger in from the mains, it will not register as charging. Once every 10 seconds or so, it will actually register the charger, but only for about half a second before it drops. It DOES however charge if I connect it to PC, Xbox or car (only wrks in the car if charging from a USB socket, using the in-car charger straight from the cigarette lighter doesn’t work). Basically, I can charge my phone off anything that isn’t directly the Mains electricity.
I’ve googled the hell out of this problem, only to find that posters will quickly dismiss it as faulty hardware; bad USB cable, broken USB port, bad charger, low voltage from mains – anything at all. But the bottom line is I do not have faulty hardware. Everything was absolutely fine until the very instant I finished flashing DeltaROM – I’m convinced something didn’t go right during my first installation since it was a bit rocky (read the original post for details).
After getting no answer from the Delta lot I jumped ship to LiquidSmooth (which is very nice by the way) but the problem remained. In one last attempt I started again from scratch. I used TriangleAway, formatted EVERYTHING (the kind that also deletes all your media) and flashed back to stock. Using Samsung Kies I 'upgraded' the firmware and I'm now on the latest official 4.1.2 release – and it makes me a little sad!
Just to back up the fact it’s not hardware related, I deliberately persevered with it to gather up as much information as I could, and here’s what I learned:
Why I'm sure it’s not the battery.
• I've tried two other batteries (3 total) and the problem exists with all 3
• The health of my battery is excellent
• My battery charges fine in other phones
Why I’m certain it’s not the Charger
• One of my chargers is only a couple of months old
• The charger I have been using is the official Samsung one that came with the phone, though I have 3 more – one BlackBerry one, a charger that came with my s1 (many moons ago) and two the same that came with mine and my gf’s phone. These are the plugs with a USB input on them,
• I have 5 chargers in all – BlackBerry, Nokia, Samsung (x3) ALL of which don’t work with my phone but ALL of which work with EVERY other phone in the house.
Why I’m sure it’s not the wall Socket.
• I’ve tried every plug socket in the house and even taken it to my parents and to work – same story.
• Everything else I plug into the sockets work just fine
Why it’s not a bad USB cable.
• I have 3 that I use. All of them will charge off of the computer, the car or the Xbox – they cease to work when I use them in the mains USB plug.
• They all work fine on every other phone in the house, regardless of if it’s in a mains adapter or a computer
• I am able to connect with all 3 cables to my laptop to view files.
Why I don’t think it’s a damaged USB port on the phone.
• It ‘does’ actually do everything it needs to do when plugged into my pc, Xbox or car. If it’s communicating well with other devices and harbours electricity correctly when doings so, then it can’t be the USB port since the way it gathers energy is the same.
So what gives? How can it be bat hardware if it works from the PC? How can it be bad firmware when I am back to Stock?
Thanks a million guys.
* Telling me to send it off for repair doesn't count. If it's something that I can do at home and it fixes my issue, the first person who gave that advice will be the winner. This does of course mean that if my phone is just downright screwed, there's a chance no-onw will win.
Have you tried to use a kernal like siyah kernal and change the chrging parameters for ac charging? (the Mah value for charging off wall socket...

Hi Koogly
Sorry probably should have mentioned this. I tried siyah and set everything to charge as much as it could - AC and USB. I also tried a lot of other 'fast charge' apps to no avail.
While the USB does charge, it's still quite slow at 460mA. Once in a while, the mains charge stays connected, and you can watch the mA level drop. It will start at around 999, but within 10 seconcd it will decrease down to 100mA, which is slower than the phone actually uses up energy.
Nobody?
Just to be clear, what I am asking for here is advice on which part I need to replace on my phone in order to fix this.
Here is what happened:
I was trying to make a bench power supply out of an old computer power supply I had laying around. Well when I went to connect the "charge only USB Cable" to the Molex connector I accidentally swapped the wire colors, I meant to use the red (5volt) but instead connected the yellow (12volt) to the USB cable. Stupid and careless mistake I know, trust me... Nothing strange happened other than the phone gave me the "incompatible charger" error. The phone will turn on and function 100% normally so long as the battery is charged via another device. For example I take my wife's fully charged battery out of her S4 and put it in mine, the phone works fine until the battery dies; the battery I swap to her phone charges perfectly fine in her phone so it is NOT a battery issue.
The phone will not charge a battery anymore, with the original charger or the other 3 white Samsung brand chargers I have, nor my car charger. After doing some research online I discovered that it was likely to be a fried USB board, which I replaced today. So the USB board and USB connector are brand new and I am still having the same problem. I also read about restoring to factory settings which I have done and also reinstalled my custom ROM. I reinstalled AFTER the error message began occurring so it was NOT cause by a the ROM update. I read that I may be able to use a wireless charger which would solve my problem, but I don't actually own a wireless charging base and I have no plans of buying one unless it is my ONLY option to fix this.
Here is an exact description of the problem:
When I connect a USB charger of any kind to the phone while it is powered off, I get a black screen and the phone vibrates once every 4 seconds or so and the battery never appears on the screen nor does the screen light up in any way.
When I connect a USB charger or connect it to a PC while the phone is on I get "The connected charger is incompatible with this phone. To prevent damage to your phone, charging has been stopped. To continue charging, use the original charger and cable that were provided with this phone." error message and a battery icon with a red "X." If connected to a PC the PC says "unrecognized USB device."
Here is my phone info:

Hardware Version: I545.06

If there is a tread that has already covered this I apologize, I did do a search and didn't see one.
Any help or information is greatly appreciated.

there is no fixing this you fried the motherboard its toast done,over with gl finding another MDK motherboard those are few and far between the charge controller is part of the motherboard you need to replace the whole thing(logicboard) you are better off buying a new phone a wireless charger is worth a shot but if the charging controller is shot its not gonna do you any good the only other option would be to hotwire the battery to a external charger (you can't simply feed 5v into the battery it will melt/explode it needs to be a regulated current of 3.4 to 3.8v at about 150Mah it will take 4 hours to charge and you will need to be there to unplug it before it overcharges and explodes

I was afraid of that.
Thanks for the info.
All of a sudden the USB port on my one year old V10 is having issues:
Won't "fast-charge" when plugged in to LG fast-charger. But does do and show that it is "regular" slow charging.
When unplugged, status bar battery icon still showing charging animation.
Does not switch (or give option to switch) to data when USB is plugged into computer nor does it appear as device on computer as it did before.
Battery is draining very fast, probably 2-3 times as fast as it should.
Also doing the following, don't know if related to USB issue:
When I power off completely, before, I had to press and hold down power button to power back on, and would also get a quick vibrate.
Now when phone is off, just quickly tapping power button for split second powers on phone and get no vibrate. Also when phone is off, plugging in charging cable powers on phone.
These issues just appeared out of the blue yesterday. Nothing has happened to phone - not dropped, exposed to moisture, didn't install any new apps, flash a rom, nothing new done to phone. It just started happening. :crying:
I would say that this is being caused by one of 2 things:
1. Bad charging adapter and/or cable. Either use another charger/cable, or buy an original LG fast charger replacement from somewhere like Amazon. 3rd-party stuff may or may not work out well, I would stick with LG if you want to play it safe.
2. The actual charging port on the phone is bad. In this case, no charger/cable will fix it. This will probably mean buying a new phone, unless you have warranty/insurance, the cost of getting it repaired won't be justifiable.
So far one of my 2 LG cables have gone bad, developed a split in the wire, now it charges my phone sometimes, but sometimes not. And it rarely works for copying files to/from PC. My other cable works fine for the most part.

I have 2 OEM LG Fast Charge 2.0 cable and brick sets, the one it originally came with plus another one I bought. I also have a second OEM battery and LG battery cradle. I've tried all these plus others I have and all get the same result.
I mostly use the cradle to keep the second battery charged and swap them out as needed each day, so I don't actually do much charging on the phone. I also use SambaDroid to move files to a PC, so the only real problem this is causing is rapid battery drain. I'm no expert but I'm guessing there's a pin in the USB port that is shorting somehow and that it's causing the battery to drain. Any hardware experts out there? I need this phone to last another year so am willing to try minor surgery if it would help and if I can find a good guide to follow.
Edit: SambaDroid not working in Marshmallow. I also sometimes just take out the SD card and pop it in a card reader.
I'm wondering if anyone has suffered with and recovered from the sudden case of no charging/USB>PC recognition?
I've seen countless similar stories across the web, covering many of the Z Family. Some were simple reset jobbies, and I've seen as in-depth as what I'm assuming is an IC being removed, flux cleaned and re-applied (w ww .you tube. com/watch?v=ZyCeNfc99a0).
I purchased a new charger port and also a new battery, as I figured with all the insane constant burning of my pocket, it could use a new one. I'd hoped it was just a charger port issue, but much to my dismay, the issue still persists after fitting them.
I've tried every single button combination "fix", and all to no avail. Multiple leads, charger units, all that polava. Checked and cleaned connections with isopropyl alcohol, checked for burned-out looking mainboard components, at least those that are visible.
I was having minor inconsistent charging issues for a while, up until last Friday. I figured it was the USB port on the phone or the leads, and put it down to general wear and tear.
Last Friday I was at my mates house with super low battery, popped it on charge round his and I noticed it had died completely and kept boot cycling, like the charger was being plugged in and taken out over and over.
I took it out and tried it when I got home with the regular charger, and nothing. My phone is otherwise in mint condition and has been looked after since day one release in the UK.
I'm wondering if some super helpful person here would possibly have some other alternatives that haven't been mentioned, whether a hardware bypass or some trick that isn't amidst the countless cries for help out there.
Many thanks in advance.
Hello,
I have a problem when connecting to a charger it will go in strange charging mode that actually does not charge. It makes the sound like a charger is connected, no charging animation on battery though...
The problem for me it was the USB cable used for charging (i have changed 5 of them in 1 and a half years). Also same behavior happens when using a under 1A wall charger.
P.S. : The USB cables that i have changed they still work fine with other devices/phones .... but not with my Z5C. I`m not sure what but is definetly something wrong withe phone usb port (and it is not dirt).
no, but
I cannot get a usable USB connection to my computer, but if I hold Volume Up while connecting the USB cable to the computer, the charger LED turns red for a moment, then blue. It WILL charge in this mode, which I think is fastboot mode. Someone said it bypasses the charge circuitry or software, which makes me think that maybe I could go into developer mode and turn on OEM unlocking to see if I can stop it from trying to optimize charging. I also have not tried all the USB connection modes yet.
I tried to charge with this blue light technique on the wall charger, but that did not work. Just ran the battery down again and I could not boot the phone.
I know if I press Volume Down while connecting the USB cable to my computer that the charger LED turns green, but I am not sure it will charge in that mode. I think this is for flashing or something, but since my computer does not recognize the USB device no matter what I do, I don't think flashing is an option.
Oh, and when I do charge the phone with the blue light special (old obscure USA discount retailer reference), for some reason the charger LED flashes white every 4 to 5 seconds, but it seems to keep enough charge to get me through at least the day until I can charge again by same method.
Maybe we can keep pooling info here. I got the blue light technique from someone else on this site, so there are people here who know quite a bit about this phone, thankfully.
Well, I had that issue, too (at least it sounds pretty familiar).

Does your phone also believe to be connected to "something" all the time?
I fear there is some IC fried, although I never dared to open my phone.
My "solution" was to talk my local salesman into giving me a (used, but working) replacement phone, and I did not want him to find any traces of DIY
So, no, I never found a technical solution, probably they just scrapped my phone for spare parts, idk.
The root cause for my error (probably) was a faulty charger, therefore I am pretty sure I fried something hardware-like, but depending on your cause, ymmv.
Anyway, trying to clean your USB port, re-soldering the connector and/or replacing the battery sounds like being worth a try, anyway.
// edit: "cat /sys/class/power_supply/usb/present" used to always output 1, even when not connected. On my now-good Z5C this works like it should (connected ->1, not connected -> 0)
Hey people. I have tried all the tricks for several days. Tried several charging cables. Nothing worked for me. I just brought a new phone, and it came with a cheapo charging cable. Decided to plug it into my Xperia and it worked. Maybe a little fairy fixed my phone when I was out buying a new one. Anyway, I'm love my Xperia Z5. Using it right now. Good luck people
