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....

Sorry if this sounds amateur, but I was wondering if I would be able to use my cell phone charger with the Nexus 7 without it causing damage. Or is the reverse true too?
The output on the Nexus 7 charger is : 5V - 2A
The output on the One S charger is: 5V - 1A
The input on the Nexus 7 charger is 100mA higher.
Now technically this means if I use the Cell charger the tablet would take longer to charge right?
But what if I use the tablet charger for my cell phone? Would it damage my phone?
I'm only wondering because I don't want to have too many cables cluttering my workspace.
Thanks in advance.

You're right about the charge time. And yes you can use it on your phone. I have a 2A charger for my g2x that's blazing fast.

It charges super slow on my GNex charger. 10% in an hour
you can use the nexus7 on your phone it will work as a rapid charge, i wouldnt make a habit of it...
Don't quote me on this, but using the 2A charger for your phone should work just fine, as it should have an internal limiter that prevents too much current from being passed through the device, damaging it. I have done that before (with a different charger) with success, so it should be just fine. Also, the N7 *should* charge on the 1A charger, just a LOT slower, and may only charge if you turn it off.
Thanks for all the quick responses guys. I just wanted to make sure I don't do any damage to them.

Is anyone else having problems charging their S4? I was using a 5V/1A car charger while on a trip and the phone was actually losing power faster than it was charging. I did have Waze open and was playing music using local files with Google Play, but my S3 was able to handle that fine and still charge in the car.
Additionally, I left it plugged in overnight for 6+ hours using the AC plug that came with the phone and it didn't charge up all the way.
Is there something wrong with my phone?

I had the same problem in my car. I had a cheap car charger that was lower amperage than the standard wall charger. This phone is designed to charge with a 5V 2Amp charger. Your screen draws more power than your s3 so 1amp might be it's burn rate with screen on, GPS, music, etc.
I got a 2amp car charger from thinkgeek that works brilliantly. It was a little pricey. Amazon has one for 6 bucks. I highly recommend buying a coiled micro USB cable so it is more manageable.

Should be as safe as using the stock charger. Even if it was a lot more powerful than the stock charger it would still be fine because the phone itself is what regulates how much power to send the battery.
Can anyone help me understand why any other charger I use on my G2 charges very slowly (and tells me so)? I will get a wireless charger soon and keep the regular one in my work bag, but just trying to understand why anything but the one that came with the phone is such a dog even when it is plugged into the wall. thanks
The G2 charger outputs at a rate of 5v at 1.8amps. any charger that has a lower amp out will charger the phone at a slower rate and bring up the slow charge warning on the phone.

And you need a USB 3.0 cable with a charger having 1.8+ amp output. I tried using my ASUS tablet charger which has an output of 2amps and it still says slow charging. I also bought an aftermarket USB 2.0 cable and used the OEM LG charger and it will show slow charging also.

Have you compared charging times between this and the OEM? The description seems to make it s match.

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.
Recently my wife broke her USB port on her n7, so I decided to just attach some wire to the pogo pins as I know there was a ground and a 5v line. After I installed battery monitor, hers was charging at 1000 to 1300ma. Mine charges at 500-600ma.
Maybe my port is broken too I'm not sure. Can anyone confirm this?

I also charge my nexus from a homemade dock at the 1000-1300 mark compared with my usb port. The usb port is so bad that most of the time I see it discharging while in use!!!
I believe this is a hardware fault as mine used to charge great through usb. at one point my usb socket stopped working altogether, I ran a soldering iron over it and it is at least working again, still slow to charge.
I have also been following a thread about this in the google user forums. One person stated that when they changed the usb board charging rates resumed to normal standards. There is a lot of people in that thread suffering from this. Bad show google.
Have you guys confirmed that the n7 charges faster off the pogo pins?
Sent from my SAMSUNG-SM-N900A using xda app-developers app
It can charge just as fast off USB I know mine does I think the problem seems to be that the ports are easily damaged and it slows the charge rate

I have been following a thread on google forums about people suffering from poor charging rates. I can confirm that many users in that thread, myself included, have found that charging through pogo pins charges normally, whilst the usb charging takes forever and even discharges with screen on!!

is that with the provided 2 amp charger?
It is with a third party charger as my charger broke, but it was the same with the original.

The 5V oem charger output 2000mA. Any charger 2A should fast charge.
Also the pogo pin can charge on 12V 500ma (which is automobile acc. standart)
See more info on Qualcomm FastCharge Standart
There's a chip that identify the power output available. So a charger 1A charger will be identify by the device, therefore it won't fastcharge.
