Just wanted to see if anyone else has this problem
My Note 3 with the official usb3 cable is only charging at slow speed from the wall charger.
I've tried rebooting still made no difference
If I plug in a micro USB cable from my nexus 4 it charges in AC mode.

Happened to my charger because it would always be seating on it and stuff. Just been using the usb charger instead.
Just test with the usb one to see if it is the wall charger's problem.
What does the extra plug do?
Just faster transfer speed or faster charge using USB 3.0?
I tested it with a standard USB 2.0 microUSB cable and it still works and charge the Notes 3
It dedicated in/out. Much faster charging and data bandwith

From what I've heard and read USB 3.0 doesn't charge faster. But it transfers days about twice as fast as USB 2. But don't quote me on that. ..

True, doesn't charge faster from the wall, but will when plugged into a USB 3.0 port on a computer when compared to USB 2.0 port.

I tested this, and it seems to charge at the same rate in a USB 3.0 port, plus it stopped charging after a few minutes. The port is a PCI Express card from Rocketfish.
Now I'm starting to doubt the accuracy of the app or my understanding of what it does.
It's Galaxy Charging Current Lite. If I launch it while my battery is charged to about 80% it says 460. If I come back & refresh the view when it is charged to 97-98% it says 1800. Why would the rate start slow then speed up as the battery fills, shouldn't it be the other way around?
A few weeks ago I used another app to check charging rates of my Nexus 4 with different cables & chargers, and this app seems to be very different. I guess I need to try to figure out which battery checking app it was.

The charge/data cable, is just a standard USB 3.0 cable, just like any USB 3.0 external harddrive cable. I am actually using a black WD USB 3.0 Cable instead of the ugly white cable supplied.
All the cable does, if you have USB 3.0 on your PC/Laptop is allow for much fast data transfer (great when transferring music or video to and from your phone via usb. Note that you need to select USB 3.0 mode on the phone.
My Galaxy S4 charges.... terribly directly connected through USB into my PC in both USB 2.0 and USB 3.0 inputs.
Am I doing something wrong, is there a way to boost the charge you get from a USB PC input?
Thanks!
Most USB ports on a computer are only 0.5 to 0.75 amps. To charge your GS4 you really need about 1.0 amps, the charger that came with your GS4 is 2.0 amps. So no you can't get a better charge from your computer.

Check the logo on the USB ports. Look for one with a lightning bolt. My laptop has specified ports that have higher output for charging.

Some laptops from MSI are supported by their utility called Super Charger. This boosts the power output but also removes connectivity (I believe). So you won't be able to connect your phone and transfer data.
There maybe be a utility that supports your laptop for boosting charging. Best thing to do is Google around for some programs.
If your laptop is old you're probably out of luck.

There is a cord that is used for external hard drives on laptops it uses two usb ports but plugs into one drive doubling the power. Just a thought. Only thing is they are usually mini usb not micro but an adapter should do it

Thanks all! I also have another problem!
I read your answers, so I decided to get a 3 amp car charger for my S4! If the original S4 wall charger is 2 Amps, then a 3 amp car charger sounds good, right?
Unfortunately, my phone gains no charge from it in both of my cards, my phones battery just dies slower when plugged into the car.
Any tips? Thanks!

Most car chargers lie about their ratings so that could be one problem, the other, is most phones see car chargers as a usb port charger instead of an ac charger so the rate of charge is automatically reduced to usb charging. Somewhere on here was a thread on how to modify a car charger so the phone would see it as an ac wall charger and allow it full output. I believe you have to open up the charger and jump a wire over. Search on here or google it and you should find it.
Could be a lot of things. But remember you phone will only allow its self to charge at a certain rate. Thus, purchasing high amperage chargers will provide no benfit.
High amperage chargers are more for tablets that require more power for their larger batteries.

Mine does that. I have to reboot it while it's plugged up to my car charger. Thought my charger was bad after taking the MJA update. Still looking for a fix....

Hey all,
The stock charger that I got with my S5 (Australian) says it's a 2A charger.
But when I plug it into the wall, it only charges at 1A.
Also happens when I use my 2A car charger.
Anyone else experience this issue?
Possibly only the cable can handle 1A have you tried a different usb cable?

Using the same app, used it on the S4 and now S5 and got the same result. About 1-1.2 amps
Ive had the same phones aswell and with the original usb 2.0 and usb 3.0 cables I get a consistant 1800mah through galaxy charging current app

Stock rom and kernel will only charge at 1200ma max if the screen is on. It goes up to 1800ma with the screen off. The charge rate is still dependent upon having a good or a bad cable though

My nexus 7 have a problem, that can turn o, every time rebooting, won't accept any charge, how can be?
...i have almost the same issue with my 2012 N7, stock&root....it just will not charge (tried different chargers!) It shows "charging" but it uncharges...now it is dead!!! ....a known issue??

Sounds to me like you either have a broken lead on one of the charging pins inside the MicroUSB charging port or either your battery has malfunctioned.
I also have the Nexus 7 2012(grouper) and have a "tighter" connection using my Samsung ATIV SE MicroUSB cable, but the cable for my Galaxy S4 tends to fall out easily.
Remember that most aftermarket MicroUSB cables do not have all the pins inside the connector and most MicroUSB Chargers only have the 5V charging pins..
Try plugging your tablet into a USB port on a computer and see what happens..
Hope everything works out!

I have changed my usb-port as well, and the battery icon when the tablet is shut off shows that it is charging, however the OS when turned on doesnt seem to recognize that the charging cable is present. Also PC connection doesnt seem to work... Any ideas?
