Hello
I hope you can help me
I have a g930u s7 model
Fast charging or standard charging dont works for me. also the battery drains fast. I already try many SAMSUNG ORIGINAL fast chargers and even other brands. And it only charges me in USB mode (as if it were charging on the computer) and takes 6 hours to charge. And also the pc or OTG does not recognize me with pendrive, mouse, etc.
What could be the problem? Or what would be the part to replace, the charger discards it as I tried with many.
Thanks in advance
Try changing the usb cable. Worked for me .
Hope it helps ??j

Inspect the connection to see if damaged, If it's ok then it's the charging circuit and needs replacing.

Hi all,
My friend's OPO does not charge when connected to the USB port of a computer. It is stock, unrooted, KK 4.4.2.
It charges fine when he charges via the wall charger. My OPO charges fine out of the box, with USB on the same laptop and port.
He does not want to factory reset and I am at a loss here. Please advise what I need to check here.
Thanks!

It charges fine when he connects it to his TV (he has the US charger but no adapter for Indian plug points). My OPO charges fine out of the box.

He can buy a universal adapter for the charger. They're pretty cheap.
It's because the laptop isn't putting out enough current. It must be at least 2a to charge properly.

The issue here is that my OPO charges through the same USB port and with the same cable. That's what has me baffled.
Well consider me baffled too.

Anybody has any idea about this issue?
The front panel of my pc case has usb ports that has trouble recognizing or charging any phone. When I plug it in, the phone will show it charging but the battery continues to drain or I can't access the sdcard. Not sure what causes this, but when I plug my phone into the usb ports in the back that are connected directly to the motherboard, then there is no problem.

Thanks for the reply but that is not it. My OPO charges fine from the same port and the same cable.
Anybody got any info on this issue?
Uh, I'd say factory reset or don't worry about it.
Not sure what you expect to hear. But that's probably the first plan of action. Especially since yours works fine.
Opo has higher power requirements. You may need a cable with a 24AWG or better rating (lower allows more current).
Does it work with the stock cable?

My OPO works with any cable, though time to charge is the best on stock cable. But my friend's OPO doesn't charge at all. Even on stock cable.
Unable to make sense of it at all. I may sound like a simpleton, but maybe there is some checkbox I ticked somewhere which is preventing this? UGH!

The phone will work with any cable. Worst-case the cable's resistance and diameter will reduce the maximum charging current significantly but it always will charge the phone.

No USB port has that much current except maybe for highly specialized ones. USB2 is rated on 0.5Amp, USB3 on 0.9
Of course the phone will take significantly longer to charge or may even discharge when used while plugged in.
I can say "me too". My one also didn't charge from powered off PC while Nexus 5 plugged in the same PC with same cable charges fine.
When PC is powered on, One charges intermittently. I.e. I plug it in, it charges for some time and then stops. "OS monitor" shows "discharging [USB power]" state.
Any thoughts?

Cannot charge OnePlusOne via USB
I have the same problem.
The problem seems to have started AFTER upgrading O/S to Cyanogen 12.0.
Cannot charge via USB either from my note PC or Mobile BatteryPak (1.7a).
Above comment that 2a power is required is surprising, as I thought 1a is standard. Maybe there is some Cyanogen bug here?
I found in some Forum to make of SETTINGS - STORAGE - USB COMPUTER CONNECTION, but I do have this setting, and still cannot charge the computer.

Quote from google
In the USB 1.0 and 2.0 specs, a standard downstream port is capable of delivering up to 500mA (0.5A)

It will charge very slowly but will charge faster if the device is off. If you're using it while it's charging it's like filling a bucket up with water that's got a hole in the bottom. It fills up. But slower than it would if there was no hole.
As for the battery pack I have a 2.0a EE Battery pack and it works fine so it might be related to the analogy above.
Sorry to bring up an old topic, But its still hanging and non has really come up with solution. So i thought let's bring some light to it.
My dad has encountered the same issue the other day, I'm basically not much PRO into fixing things like this but by turning on/off USB debugging while connected to PC and also turning on/off Developer options does makes it charging through PC again.
Previously it was charging by PC, but dad has messed up something internally and asked me for help, so this lil so called tricked work for me. I hope this will help others to.
My phone can transfer files at normal speeds in bootloader mode. It can even transfer files fine when booting up to kit kat. the issue is even though it does all I mentioned, it won't charge (or charges too slow to matter) via USB connected a PC or USB to any AC adapters. I've tried many working cables and AC adapters, could someone please help or point me in the write direction?
NOTE: It on occasion charges normally.

If it on occasion charges normally but not all the time then perhaps you have some internal damage at the charge port. Now I have no idea how to fix this but one other possibility you could try with the Nexus 5 is to get a wireless charger and see how that works out for you.

trying a wireless charger right now, same old game. slow charging still. I did notice the battery readings with Ampere, i attached a screenshot. the temp is negative -30 celsius on average often show a negative charging status no matter what charger is plugged in and EVEN with a wireless charger.
Does this mean I have a bad battery?
I'm afraid your guess is as good as mine at this point. I've never experienced that type of problem. I have experience of damage to the charge port with an old nook it behaved just like you said which is why I suggested wireless charging since we have it available on the Nexus.

yea, i bought a wireless charger to no avail. something either within the phones board or my old AC adapter had gone wonky, put a new battery in and the same thing began happening after 2 days.
Hy guys, as you can read my phone suddenly started not to charge. One day i was chatting on whatsapp and suddenly the phone turned off with 5% of battery remaining. Since that moment the phone is not charging. I change the battery and the usb port board but it is still not charging. It recognises that the usb cable is plugged in but it doesn't charge... i tried to charge it while in bootloader, recovery or with the phone turned off.. Nothing worked. I don't want to factory reset it since i have 11% of battery holding at that level thanks to the charger. DO you guys have any ideas? thanks....

Try using stock charger and stock usb cable. I also had the issue stock usb cable fixed it.
I am using the stock charger but my stock cable is destroyed. I have another cable that is really good, I have always used it and I tryed also different cables but still not charging... It just can't stop charging from one moment to another because of the cable, that cable is perfectly fine. Thanks anyway Any other suggestion?

I have someway managed to recover my old original cable but even if it says it's charging the battery is always at 0%. Therefore it's not the cable. Any other possible help??
Same problem here.... Changed the charger n cable to capdase... Download ampere app from play store... It works with nexus 5... Check for different cables

I know how these things works and I have already tried different chargers and cable and stock ones as well and it is not a problem of charger or cable. Any other useful suggestion?
Make sure that when you replaced the battery, all the cables were clipped back in right.

Yes thanks but I already checked. That's not the problem.
when i turning fast charge on, estimated time increases up to 3hr, turned off = 1h 30m from 15%... aand what's problem with it? well, my usb cable is lil damaged, iv dropped phone with usb on and it does not sit tightly anymore, but other usb cable does, so port is not broken, this might be a problem? (if it is, how fast is recommended to get new cable)
p.s usb cable' head and charger gets little hot, but phone maintains normal temperature even when fast charging is on...
p.s 2 also it does not say it is fast charging anymore in notification panel...
Thanks in advc
anyone?

i'v tried other non-original, but also non-damaged usb and it's still same... i hope my charging port is OK
p.s so i need to buy new, orogonal Samsung one?
I'm guessing the port is now damaged as you've stated that you've tried a couple of different cables and the problem persists. One of the pins must be misaligned inside there now and so its no longer functioning as it should.
Have you tried using different USB cables ? As well as different ports/sockets?

different cable is fine, no disconnect issue, but charges noticable slow, not to mention that fast charge does not work with non-original cables
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
Up
Need help.
In software, how or where is manageme the charge ? In the kernel ?
Is strange, the charge is blocking at 250ma...
