What is the extra part on the plug where the USB cable plugs into the phone? I'll guess it helps with data transfer.

Yep USB 3.0. Faster data transfer if the computer has a USB 3.0 port and the charger that came with the phone combined with that cable makes for super fast charging. Cheers.

hello guys well i have a nexus 7 that i set up in my car everything working perfect but i cant get the battery to "ac charge" im using this cable
http://www.ebay.com/itm/Usb-type-A-...G-Micro-USB-female-power-supply-/310680595889
the issue is not in the charger because the charger im using when connect to the tablet directly does achieve ac charging but when i plug in the above splitter it looses it, if the cable is meant to separate data from power than why is this happening? how can i get "ac power" or fast charging, I currently have everything connect to a toggle switch that i leave on over night, and i really is not a big deal but i noticed the other day with the navigation on watching videos that the battery is still draining.. using timur kernel
thanks in advance
its obviously the splitter, from the looks of the cable on the micro usb socket its to thin to take the power?
You need to state more info. What kernel? Rom? Only a specialized kernel will allow otg host mode charging.

If you are completely stock, the tablet will not charge while it is in Host Mode with the OTG cable attached. It can be done with a special kernel, though.
Yup, thats what I said.
I can almost guarantee it is your otg cable,get a samsung compatible otg with power cable.

I have a car install running Timurs usbrom (which I recommend over just his kernel) and its the one Im using without issue.
It is because the otg cable does not have the data cables in the powered end that is split off. They need to be shorted to get full AC charging but it is impossible with an Otg cable as it would not work for any data.

So what you are saying if im understanding correctly is to achieve true ac charging you have to utilize all 4 cables in the usb passage?

You need to short both the data pins together for AC charging. But if you do that, OTG is gone.

You are just using the kernel,usbrom is his full cm10.1 based custom rom. The proper otg cables need to have pins 4 and 5 (ground) together on the tablet micro usb end to activate the ofg and power,that why you need the special cable.Your cable only power the device on the usb end not the tablet,it says no device charging in the description.
Also with Timurs kernel or rom the data wire cross isnt needed,or the otg devices wouldnt work.

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....

It is a USB 3.0 port.
You can still use a standard micro usb charger in the right hand part of the port. It'll just charge slower.

I use a USB 2 cable every time. IN fact, I have never plugged a 3.0 cable into my phone and it charges pretty quickly.
