Weird USB problem / charger issue ? - Nexus 5 Q&A, Help & Troubleshooting

Hi,
I'd like to know what you think of what happened to my Nexus 5 and Galaxy S Advance last week.
My car usb charger died and I bought a new one rated 2.1 Amps for 10 Eur. On the Nexus 5 fast charge was enabled, on the S Advance I had no such thing. I used several USB cables with this charger for several days as I was driving a lot.
Once back home I could not get any USB data transfer on both phones, of course I disabled fast charge on the Nexus, furthermore the S advance is now very difficult to charge switching all the time between charging/on battery.
I've tried 4 PC, 4 operating systems (XP, 7, 8, latest ubuntu) and 4 different cables, under linux lsusb shows me absolutely nothing even if both phones are in download mode so I'm afraid the USB ports on both phones are broken.
Do you have any idea on how this could have happened ?
P.S: I've tried all known tricks on both phones to get USB data transfer back with no luck.

Sounds like cheap charged ruined your phone. Perhaps send one on for a technician to assess. There's nothing we can help with if you've tried different cables and computers

I don't know if USB file transfer will be possible but you can surely use a wireless charger to charge your nexus 5. Take your phones to the service centres. Sometimes if there's an electric shot at the port, it mightn't work. They might fix it if this is the case. If this isn't the case & if you've damaged the USB port, I'm afraid there's nothing you can do but change the entire motherboard to get it working.

Thanks, I'm aware that most probably my phones are broken, but I was wondering how a charger could do that ? Do you think it does not regulate to 5V but sends a weird voltage like 6.something ?

May be.. Poor quality chargers are bad at voltage regulation. You should have used a good quality charger for your costly phones. We learn from mistakes, but be careful the next time. I hope your problem will be resolved.

Well it was not the cheapest one, I was in a hurry, stopped at the nearest computer shop and took this one. Btw Google sends me a new phone so everything is OK, but if I were not 600km away from this shop I would go back there and have a men to men talk with the manager...

there IS a difference in usb cables

I have read so many threads with problem x solved by using a quality USB cable, and yet I still find others arguing that there is no difference in cheap cables. In-fact i have just had a discussion about this with a friend yesterday so i thought i would just let everyone know - USE A GOOD CABLE!
To test this I used an ebay cable, oem samsung, oem moto, and a case logic cable. I then simply transferred a small 6 mb file and a larger 200mb file to the phone.
Ebay - phone wouldn't even connect to pc.
Sam - both worked
Moto - both worked
Case - 6 mb worked, 200 started and then completely froze forcing phone reboot.
So again, especially when flashing, use a good cable!
Good to know. Thanks
Just another heads up... My wife has a Motorola and I have the siii. Using my siii cable, both of our phones charge at least three times faster. Using the Motorola cable, both of our phones charge much slower.
Another heads up... Get the best of both worlds, high quality and low price on a usb cable. Go to monoprice.com!

Most Likely those talking about difference in Cables could be talking about how each manufacture alters their cable.
For example, Moto and Samsung have a Resister that links 2 of the 5 pins which is hidden in the plastic. Reason for this is, Car docks, it would tell phone to open car dock App etc, Same for media docks.
Charger usb cables are same because some phones can handle a higher amp of charging which charges faster while a standard usb cable needs to made to have a limit to not fry the device it is being used on.
Hope This helps, i know it did when I learned this,. Now it makes more reasons and ideas for Mods...LOL

If you're using a charger for a different device, it's likely that they have different amperage. A 2 amp charger will charge your phone a LOT faster than, say, the 0.5 amps off your computer's USB port. In this case, it's not the USB cable itself, but the amperage of the transformer in the charger. Some may argue that the slower charge is "better" and will help your battery last longer.
If you're using the same charger with different USB cables, then this is news.
I haven't even used the OEM cable that came with my GSIII. I picked up a 6 foot no name USB cable from newegg for $1.39 and it works fine.

Was going to point this exact thing out. It is also possible the cables could be rated for passing different rates but it is much more likely that something is putting off more power so it charges faster. I do tend to agree though that slower is better since you can pull the plug faster and not overcharge
Over time I end up having loose connection problems with virtually any microusb cable i buy, including from monoprice. At first the cable plugs into the phone fine and charges. Overtime somehow the microusb part that goes in the phone is looser in the phone than before, and i have to angle my phone in way to get it to start charging. The slightest movement causes the charging to stop. I have had this problem with almost every micro usb cable i ever owned ever since I got an htc thunderbolt and the problem continues now with my s3.

going to mono price. I'll report the results.
One thing to keep in mind also is that most, if not all, USB cables aren't shielded so the longer they are they degrade the transfer speeds etc. I don't think it would make a difference for charging, but to transfer data a shorter higher quality cable would be your best bet. I don't know if the degradation would be noticeable tho...

You wont be disappointed. Quality products at great prices. They also stand behind their products if, in the rare event, you have a problem with one.

When you say the transfer started and then froze, I would have to ask what ROM you're running. If it's TW or TW-based, I'd be much more willing to blame the software than the cable. Using Samsung's MTP interface, I have had plenty of large file transfers crap out using both high and low quality cables.
Either way, this test is hardly complete. Obviously somethings wrong with the Ebay cable, but for the other tests, you need to run them more than once. To give any statistical significance to the data, the tests have to be run a bunch of times. Otherwise it is (as far as you know) just luck.
Also, as others have said, I think the primary differences between cheap and "quality" usb cables are
Amperage (which is mostly due to the charger, not the cable, but generally you want a cable that can handle it)
Quality of the connector (cheap cables generally have flimsy connectors)
Quality of construction/Durability (may work fine, but die after a month or two).
I don't think data transfer is something that is really impacted much by the quality of the cable (until you hit that point where the cheap cable just stops working). Getting back to my earlier point about the limited testing, I think if you ran the same test a whole bunch of times (like 100 times for each file on each cable), you'd find that as long as the cable actually works (which seems to exclude the ebay one), they'd probably perform about the same on average.
Just my two cents.

Very strange charging problem!

Ok, first a little background on this issue...
After having my S3 for about 13-14 months I started having charging issues. The charging port was very "loose" and I had to make sure my charger cable was in just right to get my phone to charge. This was annoying, however was out of warranty and didn't want to pay vzw for an insurance claim. This got worse, and eventually I noticed my phone would only charge with 1 specific usb cable, 1 specific wall charger, and 1 specific car charger.
Well, I finally called Samsung and explained the situation to them and they had me chip my phone to them and they would repair it, free of charge. When they had it, they replaced the charging port, the headphone jack, and the screen. I received the phone back after couple weeks, super excited, and immediately charged it up with the cable I had next to my bed. New charging port felt perfect, nice snug fit, etc... Well, after a few days i hooked it up with the original usb cable that came with the phone, nothing happened. So i started messing around and realized that the only usb cables that will charge my phone are Motorola brand cables! At least the 2 cables I have work, and not a single other cable I've tried works! This includes stock Samsung cable, many cheap 3rd party cables, other friend's S3 cables, none work. Also, I have this cheap car charger that is the type you plug a USB cable into that works, however any other car charger I've tried does not work either.
Also, when i say the cables won't charge my phone, it also won't connect the phone to a PC. They do absolutely nothing.
Does anyone have ANY idea why this is happening?!?! It was an issue before Samsung repaired my phone, they replaced the charging port, but I still have this issue!! I can send it back to Samsung for them to look at it again, however my backup phone, a Razr Maxx, just died also. Seems like the battery went dead and now I can't get it to charge, but that's another issue.
So, any ideas?!

What rom/kernal
It doesn't matter. It does this when it is totally stock and rooted. Right now I'm not rooted or anything because it looks like it may be going back to Samsung again.

I think the smart charging circuit may be messed up
Really? How would that cause the phone to not work with any cable except a certain brand?? I'm just really curious and this is driving me insane!!

I would say you are putting mechanical stress on the charging port. This could be from some misaligned or mis-made cable or somehow pressing or pulling the charge cable when its connected. I've never seen this reported by anyone else, but the mechanical connections are not indestructible. If it were a common symptom with 100 million S3s having been sold, there would be a firestorm of complaints.
I have a similar issue. I'm not sure if it's the device or the ROM (CM nightlies).
Certain cables force the screen to turn back on, which means I get negative charge because the screen burns more than the charger is capable of supplying. Other cables are fine. I'm still looking for the pattern, it's super annoying and causes me to have to turn my phone off completely at times so as not to lose my battery altogether. I'm still trying to solve this, any help would be appreciated.

Further info- it's not the cable, it's the converter at the end. I think it has to do with amperage of the charger- if I use the stock samsung one I'm good, it's putting out 1.0A. If I use others that are fewer amps (like 700 mA) it's unpredictable. I suspect a kernel thing, I might download different kernels to play with it.

Always use chargers that is 1 A - 2A the circuit controls most of the charging regulating amps and voltage
Yes, I agree about using good chargers, but my phone wasn't always this way. It used to charge with anything, but no longer.
I enabled fast charge on Imosyen's lean kernel. That might have made a difference, but I'm not positive yet.

Phone destroying usb cables

Hi!
I'm having a weird situation here, I've had my oneplus one for about a year now and I noticed that it has been destroying my usb cables since a month ago... I'm using the stock oneplus charger or a different one, it doesn't make a difference as the cables still break. The cables just stop working completely...
Starting from today even my stock oneplus one usb cable is starting to die as my phone won't stay connected to both my laptops (linux and windows) for longer than 5 minutes, another thing I noticed is that sometimes when I plug my phone into my laptop, my laptop screen just goes black and starts flickering.
Does someone know what's going on here?
Thanks
maybe you can stop sleeping with your cable
The charger can't give more than 2A, so its impossible to break a cable by eletricity.
Never heard of that and I've been in the electronics business since a long time.
The connection loss I know is that I have a hard time copying files over usb with my phone sometimes. Just stops and then the whole process hangs.
My advice, and this is for everyone, is to buy a charger doctor or alike. Just go on ebay or aliexpress and you can get them for less than a sandwich. This takes out the guessing if a cable is ok and what current flows through it etc ....
9 out of 10 cables that I have here are crap. As a matter of test I just ordered a Blitzwolf cable that states that it can charge at 2.4Amps. Not so on our Oneplus it seems. The voltage drop is to big making it go to a lower charge current. The oneplus with the original cable goes to 1.8 Amps when the screen is off and the batt is less!!! than approx 85% empty
The only cable that can is the original one and the one I soldered myself.

See man its not due to the phone destroying cable. But i think it could be that either you are using a bad quality cable, or bending it too much or your power socket is faulty as the phone cant make your cable work bad only the power socket can.

Honor 8 Charging/USB Connection Issue

Currently i am dealing with an issue with my Honor 8 which deals with fast charging and connecting the device to a PC. My device takes between 5-8 hours to charge, i've also tried another Honor 8 USB Type C charger which belongs to my friend. And It's still not working. It also won't connect to any PC. It always shows that the device is not recognizable and or has malfunctioned. Funny thing is that i sent it in for a Warranty Repair which once i got back, still has the SAME issue!! They "Claim" to have changed the USB Type C Port, Battery, and Charger with USB Type C cable. Spent plenty of time on the phone with Huawei trying to find a solution but i'm not getting a great solution. They escalated the situation to "Higher Up" after i spoke to a manager (Second Time) to see what else can be done. I'm thinking motherboard kinda fried a little one day while charging?? Some hidden Toggle within settings to enable fast charging and PC connection?? Anyone else having this same issue??? This happened out of nowhere as well. One day working and the next Issues everywhere! Sorry for the long Rant. But i'm still wondering if someone has pr had the same issue or kinda the same issue. I can't be the only one with this issue.
Sorry to hear but this happens to the best of devices.. At least Honor/Huawei are investigating the problem. But I would of thought they would conduct a test on your phone when it came in and again before sending it out to you. Still they would have to put on their jig and run a full test and or ship your out a replacement device.
i would suggest you to give it and get back another device from service center.. i think , you got a faulty unit.. bad luck..

Yeah, if you have just received your device then I'd send it back to Honor and request for a replacement unit. As yours could be faulty. However if you've had it for more than 14 days then you will have to send it back to their Service Center for repairs.
Another with the same problem here...
I bought mine from a guy (second hand) at a very good price. The Fast Charge never worked and when I connect to a computer I have the same problem...
The weird thing is that if you try to charge with a power bank or a USB from a computer or laptop it charges very fast... Very. But to the AC power it takes ages. I also try with the Charger of another guy and in a shop and never have Fast Charging... Don't know what to do because for the rest the cellphone really work well.
Same problem as above. USB charging seems to work fine but AC charging is unbearably slow (50-300 mah, 10-20 hours to charge). Running stock rooted Emui 4.1. I've tried factory resetting, unrooting, relocking bootloader, rerooting, and flashing backups from when it was working and nothing seems to have made any difference. Since USB charging works normally I hope this is just a software problem but Honor needs to look into this.
The "device is not recognizable and or has malfunctioned" sounds like you're using Windows 8 or later, so the OS should have USB 3 support baked in. Did you install HiSuite and the driver for the Honor 8? Although it's a USB type C connector only 2.0 transfer speeds are supported, so if you've got a cable with a standard USB connector data connectivity try a 2.0 port. Are you seeing any Unknown Devices in Device Manager? And is the Phone showing up?
Also, now that I'm thinking about it, PC data connection is turned off by default and has to be turned on everytime you connect the Honor 8 to a PC. There's a prompt that pops up under EMUI 5.0, but I think you had to manually change it from Charge Only to MTP/Device file manager Mode.
Fast Charging with an AC adapter only works with the charger that comes with the Honor 8 (or other Huawei phones that Fast Charge at 9V/2A). Qualcomm Quick Charge adapters will only charge at regular speed (probably 5V/1A). If you use an AC charger from an old flip phone or something a lot of those are only rated at 5V/150mA and might not provide enough juice to keep the battery from depleting if you're using the Honor 8 while charging it (and take 20 hours to hit 100%).

I am using the charger included in the package and its not working properly, also I tried with other Honor 8 Adapter that worked on my friends Honor 8 and is not working on mine. Also tried on My aukey Quick charge 3.0 compatible AC charger and is still slow as *****. If It is connected to acomputer USB charges faster than to the power line so i assume is a software problem or bug that do not detect properly the power any solution?
Can not send it back to Huawei because I bought it as second handed...

The EXACT same thing happened to me! About a week ago, my phone just stopped connecting to the MacBook. I then tried it on my windows computer, at work, and still, nothing.
I've been through the settings and changed everything and yet it is still not recognised by a computer.
My next option is to do a factory reset with the phone but I am determined to not do that as I don't want to lose so much data.
Did you resolve the issue?

Unfortunately I did not, Huawei would not do anything else, claimed to changed parts and nothing fixed the issue. So I sold my device for 80 bucks. Did you use any new chargers, car chargers, or change usb cables? I used a car charger with quick charge and a new us cable. Was charging my device while driving and noticed my phone was extremely hot. Must of unsoldered something on the motherboard.

Well I'm currently using a cable I bought from Vanguard (Shenzhen, China) and it still works now. One thing I have been doing is gaming whilst charging. The phone seems to feel hot but I didn't expect it to do this. I'm guessing the same thing would have happened if I'd been charging with the original wire which I keep at work. The constant use must have damaged it. :good:
Hello guys!
I have the same exact problem with me honor 8.
Takes forever to charge via DC and I cant access phone storage via use cable when connected to PC. I have bought and changed loads of USB cables but the problem still persists.
Anyone please help before I go crazy and ditch the phone !!!
I'm affraid there is no solution. I sent my phone back to repair centre 3 times with this problem. (No fast charge and PC not recognise. They replaced the mainboard at the end. It solved the problem for 2 days and dead again. I just gave up and living together with this fault however it's bloody annoying especially when you would like to download your pics and videos. :crying:
I have exactly the same problem, as described, with mine. It happened out of nowhere as well.

Changed usb port but still slow charge

Hi all, i have a problem with my s6. I repaired my s6 usb port and changed it with a new one. But still my phone charges at 250mah instead of 2000 and my pc wont recognise it, any suggestions?
A kind of "script-type" solution, but have you tried different USB cable? I suggest you buy a proper one, like 28/24 gauge USB cable.
These are a bit more expensive, but charge very well. Much better quality and charge faster.
Already changed ton of cables and usb ports, still the same problem

I think your charging ic on logic board needs replacing. Only micro solderer people can replace that. Might not be worth for you.
i ve lent it on a samsung repairer guy. they changed battery, connector and installed a new os. now they said they should give me it tonight or tomorrow.. let s see if it works

The way I read that you're expecting to get rapid charge from pc ports. Need a rapid charger for rapid charging.

Same issue here. Think its related to a charging chip
Hi,
I've got the exactly same problem here. Repacinfg battery and the USB port of the phone did not solve the problem. Did your repairing work out? Any more ideas?

Hello all :
I have exactly the same problem that you all I have 250 to 300ma really charge, that it is any charger of 0.5 amps 3.1 amps either with a quick charger from Samsung or quick charge 2.0 or other, any cable too, and any rom, tested Global, Lineage and stock.
Oooo, and i tested with a custom charger, 9v 2amps, nothing change !!! 0.250amps and 5hours to 50% -> 100%....
Is really strange problem.
Any Idea ? is possible to limitation software ???

Yes is possible, but here i dont know.. beacause, it would have quite different effects depending on the chargers and on the voltage. here we have, in my case, the same problem regardless of the charger amps or voltage.
this is more like a software crash of the chips in the worst case.
Other hand I noticed that I had lost all utilities USB my phone example when I plug it on my computer it is absolutely not recognized... Any Idea for that ???
Thanks

In software, how or where is manageme the charge ? In the kernel ?
Is strange, the charge is blocking at 250ma...
