Try another charger. Quite a few people seem to be complaining about the OEM Sammy chargers going kaput. Also could be a cable problem (broken wires) - I had a similar problem with my wife's tablet, fixed by replacing a cable.

Before buying a new charger, I would suggest confirming the exact problem first. You may be able to borrow a charger from someone (any USB charger with approx 2 Amp output will work, for example, from an iPad), or a cable. See what fixes the issue, and get a replacement. Also, if you have some average soldering skills, the cable can fairly easily be fixed at home (in case it is a faulty cable) - the wires usually break at the connector, and the OEM Sammy 30-pin connector is snap-assembled, not glued, so you can take it apart and put it back togethet. Good luck!

mOrE URGENT HELP WATED - Have I fried my Nexus One?

Hi guys,
I stupidly plugged my Nexus One USB cable into a higher voltage charger in my car, about 8v-10v I think, and I could immediately smell burning. I unplugged it straight away and the phone died. The result was;
1. I could no longer charge it off the wall charger or computer USB charger, just got zero response, no led's etc.. seemed as though the phone was totally gone.
2. Then I took the battery out and charged it in my external battery charger. When I put the battery back in the phone it turned on and worked perfectly!!! although the battery didn't seem to last as long.
3. When it was powered on an working, it wouldn't pick up the USB connection to my PC. Did nothing.
So.... it seems as though the USB port is obviously not working. Would this be the extent of the damage or would it be something more serious in the phone?
Would the official Google dock allow me to charge the phone and connect it to my computer given that it uses the 3 pin method and not the USB?
Any help would be greatly appreciated.
Cheers,
Morgan
Ahhhh the smell of a resistor going. And within a circuit when one major component goes it will drag some others with it. Which could explain short battery life. Back up your stuff. And look into your options to replace device. Unless you have extencesive knowlege on micro surface mounted printed circuit board components and measureing values.
good day.
I don't have any knowledge of circuit boards so is there any other options to repairing this device? It is basically brand new!
Is there any chance that a dock would allow me to charge it?
If not, can I replace the main board? I disassembled it yesterday and know how to change it out.

Just guessing, but no. The cooked components for the charging circuit would also be in parallel to the dock port.

Charging port pins lifting

Hi I noticed a while ago that pin 30 on my charging port of my tablet was lifted some so I pushed it down with a toothpick. There wasnt an issue with the tablet before, it was just something I noticed. I ordered a cable from ebay, probably a knock off, and it worked for both charging (with the use of the p1000 adapter) and for data transfer. I was using the tablet mostly for debugging and movies. I recently had it charging for a while using the rocketfish usb hub and the p1000 adapter. I tried to plug in my tablet to the pc with and without the adapter and my pc was telling me that it had an unknown device plugged in. I looked up what exactly pin 30 was and it is a ground pin. My question is would that pin affect the ability for the pc to data transfer and recognize the device? The cable currently only works for charging and that is with or without the P1000 adapter. Other than that it gives me an unknown device when plugged into the pc. I dont have another tablet or cable to test so I may just order an official cable and charger if the ground shouldnt be an issue.
Have you installed Kies? Windows cannot recognize samsung galaxy devices without it
My cable stopped charging all together. I ordered another data cable to see if my original cable was faulty. Hopefully that was the problem all along.
I got my new cable in which btw is alot more sturdier than the last. I plugged it in anticipating an error and behold! My pc recognized my tablet and began to charge. The data part works because it instantly showed that the tablet was in debug mode. So my pins were not a problem, just my cheap chinese tablet cable. P.S. I did not have to install that software and if in the future I come across a problem then I will try out the software. Unless there is a benefit to installing the samsung software? feels like an iTunes type of software. Thanks for the suggestions and hopefully this will help others in the future.
:good:
Thank you for posting your fix for your question. It drives me crazy when people ask a question. Then later reply nvm I figured it out. (And don't explain what they did) or not even reply at all.
I think I have same issue. My stock cable won't charge anymore. Do you have a link where you bought new charger? Or what store did you go to?
I ordered one from amazon and it was a knockoff that gets a red x over battery icon :/

Did you order cable only?
Are you sure there is nothing wrong with the charger base?

No I order this combo kit with wall charger, car charger and 30 pin USB cable. From amazon
Weird cause the car charger works amazing. Can watch Netflix w/ full brightness and still charge. While the wall charger will only charge if shut down
But about original charger. I was mistaken. I had a 6ft. Extention cord that I would plug it into cause original cord is way to short. And come to find out it was the extention causing the issue.
But I'm still interested in a Spare wall charger that actually works. Lol where did you get yours. Is it just as good as stock

I've experienced the same with extention cord, wonder why the amps get lost on the way into the battery?

Well technically the extention cord isn't putting out the same amount of amps as the wall outlet. Especially when the gauge of the wire is way smaller most likely. But I like to use my tablet while charger and refuse to 3ft away from wall so its kinda neccessary lol

long charging time

Hi, i know this subject is already exists in here, but it still have no answer. My sensation need 6 - 8 hours to fully charge from 10% to 100%, is there someone can help me to solved my problem?
This happen everyday, so don't ask me to remove the battery and try again because i've tried it.
Are you charging your mobile via a charger connected to a power outlet or are you charging via usb connected to a pc? How old is your battery?
it is a common HTC's issue after rooting the device
everyone has percentage mireadings while charging the device

Has it always been like that or started happening? When mine started doing that I replaced my battery, charging times went back to normal and battery life was a lot better also.
It happens to me with my original battery which I think is dead because it lasts not much time. Buy on my anker battery it charges really fast, with the same charger. So the problem is your battery I think, as on mine
Sent from my HTCSensation using xda app-developers app
What rom are you using. Sometimes my sense 5 rom misreads ac for usb and charges damn slowly.
Happy to help.
If your charging via usb connected to pc then charging will be half day, its because usb port is for data sending and not charging, so USB outputs very low volt charge and so device like phone charges so slow
If your charging with adapter into AC outlet, you could check if your using right cable(there are data cables where there are little wires inside so again it cannot output that power to the device and there is cables for data+charge with bigger cables inside)
P.S. Stock HTC cable provided is not the best wire....
Mine sensation is charging about 2h40min from discharge(10% - 6%) to full charge(100%)

It's already happened for along time.
When first purchase it is not like that.
I've replace the battery, but not with original one nor anker, and the charging time become faster about 1 hour than before

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?

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

Question Not charging

Guys, please tell me how to solve the problem: phone is connected to the charger, but it says that it is not charging.
Previously, he calmly charged, but now he does not want to ..
The wire and power supply charge other devices quietly.
You should try another cable and charger block. Move the connector around in slow increments to see if the lightning bolt shows up in battery. Reboot the phone and check. Common sense is to check these things

The strangest thing is that the non-working cable used to work perfectly. It even now charges other devices.
I tried another cable and everything works, I don't understand why the Pixel doesn't want to charge from the old cable ...

It's about the phone itself. That cable charges other devices and used to calmly charge the pixel, but recently stopped.
I tried another cable - everything works. But the current one is shorter than my last one by 2 meters
Same for me all my previous huawei supercharge compatible cable are not working with the pixel.
