N910c Charging very slow on PC - Galaxy Note 4 Q&A, Help & Troubleshooting

- Tried on All my PC's USB Port ( both USB 2 and 3 ports )
- Tried using Original Samsung Galaxy Note 5 Cable
- Bought and tested Aukey and Anker USB cables from amazon
- Bought new Original Samsung Note 4 Battery
- Charges around 2-4% an hour @ PC , so download an app "Ampere" , it states that i'm only getting around 80-120ma
- All cables works perfectly fine on the power outlet.. both standard and fast charge method
- Data Transfer is also fast
So my PC is probably the culprit ? but all other USB Devices works fine ATM

It's weird i know but you trying the usb cords. like you said pc, any major dust build up in the ports i have seen issues like this but just cant remember what the fix was.

You aren't going to get the fastest charging speeds when charging your mobile device via a computer's USB port.

Really? I didn't think you could. I know for a fact that fast chargers have the ability to charge a device using a higher voltage and amperage than a regular charger. I didn't think that fast charging via the USB port of a computer is possible.

Okay, go to asus site and see -mobo model sabertooth 990fx r2.0( it actually for iphone,ipod, but work fine with my gsn4)
When said 'fast charging' i mean it faster than normal USB charging(but ofc not same like regual Fast Charging 2.0)
I cant remember,but it show me 800-1000ma

Moded my usb charger, tab will charge anywhere !

Went to local electronic store and rigged up a mod for laptop charging, it basically charges with any usb port. Time to make a few spares .
one thing in the laptop it wont transfer data but it charges with my 1 dollar cigarette charger lol
why was this needed?
(new to tablets, waiting for an HTC tablet)
The tab doesn't charge when connected to a PC.
Any tutorials on how to make and items needed?

Interesting... Why is that?
are those resistors connected on pin 2 and 3? or better yet... got diagram?
The tab needs a power source that produces 5v @ 2 amps before it will charge properly.
Mine charges fine with my laptop...I beleive it only trickle charges, alot slower then the wall plugin, but it does charge.
wow 2 amps?
USB spec is max 5v 500mAh or 500mw? (2.5w ~) ? ... confused.
USB will charge the tab. However charge time is much longer due to lower USB power output.
When I go to Menu>Settings>About Tab> Status it says it isn't charging when it is connected to my laptop and the battery icon has the lightning bolt charging symbol but has an 'x' next to it so I assumed it was telling me the truth. BTW what clock widget is that in the OP picture?

While that is the USB spec for devices that are intended to use USB for data, occasionally you run into devices that will trickle charge off a 500mA connection but require a higher amp connection, usually provided by a specific wall wart plug, to rapid charge. The iPad had a similar function/issue if I'm not mistaken.

The galaxy tab charges just fine through usb connection on a pc or laptop, if ur doesn't u have two things to check, first are u using a usb2.0 or higher port and is your device set for usb storage file transfer, u can check in settings while connected to a pc or laptop, I charge my tab almost everyday using my pc as I transfer a lot of files daily, I don't even notice a difference in charge times compared to charging via an electrical outlet.

USB charging

I've noticed when I have my tablet plugged into my computer via USB it doesn't appear to be charging. The battery icon is showing a red lightning bolt. This is different than when I have my tab plugged into a wall socket.
Working as intended or..?
Your PC USB port can't supply enough juice (500ma max) compare to your wall socket (>2000ma) to charge while power the tab. Turn the tab off and your will get some charge off the USB port.

It's been charging my tab for about a month now with no problems at all, but I'm not here to argue, if you feel that you know more than I do. I've charged the tablet using that adapter from my laptop, PC, and Energizer XP4001 Power Pack.

The focus charger is rated only about 700ma (same exact one as Captivate/SGS), marginablly better than PC USB. GT 10.1 has a rather large battery and hence it requires much larger charge current. You don't see any laptop get charged via USB, do you?

Is that through the orginal AC adapter or through PC USB?
Turning off the tablet and charging it via USB works, but it takes forever!

And you are not the only one who is waiting twice as long before his tab is fully charged. Then we can open a topic "Why does it take so long before my tab is charged?" As foxbat stated: You don't see any laptop get charged via USB, do you?
So if I say your adapter doesn't work its just as accurate as your answer it does work.

Hey, I'm not here to argue with you. I'm just an idiot.
Go about your business, and don't listen. I'm ok with that.
First of all, not all USB ports are equal.
On many modern PCs, the USB ports can deliver more than 500mA over USB if required. This is definitely true for pretty much all Macs since 2007, and quite a few mainboards from other manufacturers (see this article for some background).
Secondly, I've had one of these adaptors for quite a while now, and have used it regularly to charge my Galaxy Tab 7" which uses exactly the same power supply and cables as the GT 10.1. I can categorically state that when using this adaptor, it the GT7 does charge from a Macbook Air and a 5000mAh external battery that has a 1A output USB port labelled for an iPad.
Whilst it might not be as quick as the wall charger, it is definitely much faster than attempting to charge the GT7 from the same devices without the adaptor, even if the device is in use.
I've not formally tried to charge my GT10.1 with it yet, but I did check to see if the "not-charging" indicator went away (which it did), so I rather presume it will work much like the GT7.
Regards,
Dave

Hi How much time its taking to get fully charged with USB 3.0.
Are you able to transfor the files faster using USB 3.0 than 2.0.
Even I got the same problem. Exynos processor is reported having high temperature while charging and running processor intensive apps.

Yes, It is totally normal.
I have 3 S5's in my friend circle and they all heat up while charging or playing HD games.
And it doesn't make sense charging it with 3.0 USB through AC adapter.
It should not affect charging speed.

As far I know, Samsung mentioned to use that USB 3.0 Cable in USB 3.0 Port of the computer for faster charging.
Do you think your AC Adapter has USB 3.0 connecters inside it?

I am just trying to clear your doubts and everybody Else's.
Connect your phone with USB 3.0 Cable to Laptops/Desktops USB 2.0 Connector port.
What will happen is Windows will alert you saying "This device can perform faster if connected to USB 3.0 Port"
Now open "Battery Monitor Widget Pro" and check charging mA values.
Second step,
Connect the phone to USB 3.0 USB Port to Laptop/Desktop.
Windows will not alert you anything now.
Now open "Battery Monitor Widget Pro" and check charging mA values.
If you are getting confused how to differentiate USB 2.0 and USB 3.0 Connectors then go through the attached images.

I knw d diff between 2 ... I m telling u that the thing is that .. transfer rate of charging is more ... not the apmere changes voltage remains d same but the rate of charging increases ... due to use of port 3.0 ... I had tried both ways using 2.0 n 3.0 n there is drastic diff .. in data transfer as well as charging ... I just want to let u knw that the cable ... matters .. ya port matters in case of data transfer thats why ur desktp say that device can perform faster .. dats in the means for data transfer not for charging charging .. desktop or laptop are not made for charging ur cell phones so dont treat them like a charging station ... try using both the cable with ur charger u will find the result ...

Fast Charging via USB-C to Mac?

Hi there
I used to be able to get fast charging when connecting my S6 to my MacBook via USB.
Now I connected my new S8 to my MacBook Pro via USB cable (+ USB-C adapter) and it's charging painfully slow.
Is the S8 no longer able to get fast charging when connected to the laptop?
Is there any other issue like maybe the USB-C adapter/ converter? I tried both the Samsung USB-C adapter and Apple's with the Samsung charging cable but no fast charging. Would I need to get a real USB-C cable (both ends)? Or is it just not possible anymore at all connected to a laptop?
Thanks

Because most people use the USB cables for data transfer as well, and most computers contain a USB A legacy port and no USB C.

Pixel and MacBooks with Type-C charging use the Power Delivery standard from the USB standard. Samsung uses Qualcomm Quick Charge 2.0 on the 7 and 8, so you need a supply with the orange or green connectors.

Well they're not compatible standards. Apple and Google went with the USB standards set in Power Delivery. Qualcomm are using their own proprietary system, which so happens Samsung brought to the S8.
