[Q] does this support fast charging and come with a 2 Amp wall charger?

i ask because the Galaxy Note II charges really fast with the included 2 Amp charger despite the huge battery. so does it?

It will support 2 amp charger but it will not come with a 2 amp wall charger.

I had read it does come with the so called rapid charge charger, where did you read that it would not?

Anandtech said it came with the same wall charger as the Note 2,which is 2 amp.
"This signaling is essentially Samsung's proprietary tablet charging signaling which they've employed on the Galaxy Note 2 and now SGS4, in fact the two use the same exact charger, so it's worth tossing out your old ones and getting the appropriate one to take advantage of the faster charging."

so even tho it has quick charge, its still slower than the s3? oo wut? it should charge twice as fast with a 2A charger vs 1A. i know the battery is a bit bigger, but it should still be significantly faster than the S3

Quick charge to my knowledge is strictly for usb charging. Wall charging is unaffected by this tech. 2 amp charger for a phone is damn fast, trust me.

The included 2 amp charger seems pretty quick to me. I never owned an S3, so I can't compare to that.

thanks for the reply!

I'd be interested in seeing if the phone actually draws 2 amps while charging or if it limits itself to a 1 amp rate of charge.

got the i9505 today, it comes with a 2A charger and it definitely charges up rapidly. I used the galaxy app from this forum to check charge current and it is flagged as 1900 mA.

For me it is not charging trough the PC's USB:crying:

If the phone's normal current draw is 1900mA, I wouldn't expect much of anything when plugged into a 500mA USB port

Can confirm it comes with 2amp charger and charges fast (Can only compare it to my S2 but I would say its charges quicker than that). Phone does charge via USB but very slow.

It is realy weird, that it is no possible charging from pc!
SOLVED: It was blocked by Battery Monitor Widget

So does or it doesn't support quick charger the samsung galaxy s4 i9505 android 5.0.1?

[Q] Quick Charging Question

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.

My stock Samsung 2 amp charger and cable works great. No slow charging.

[Q] How can I get a faster charge from USB in my PC?

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!
Sent from my SPH-L720 using xda app-developers app

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....

Charging the galaxy S4 using a powerbank/USB

Is there a way /mod to change the current when charging from a USB/ Powerbank?
I am using a powerbank with 2.1A output but when i use it in my phone i get 500mAh only.
Thanks!

Hi,
Are you sure it's not the cable that is causing the problem? Does the device uses the whole current when charging from the factory wall charger? It's either this or your Powerbank doesn't give you the proper current.

using the cable on a wall chargee gives me 1200mAh average
1900mAh maximum
so i don't think it's an issue.
furthermore, I am able to chage an iPad using the same powerbank and it charges nicely.
i was just thinking i saw something in before where it changes the current from USB.
well thanks anyway. i guess i'll have to replace ny powerbank

Samsung 2A charger head degrade?

Hi, is it possible for a charger head to get degraded?
My s5 charger used to to able charge at 2A, but now It can only charger less than 1A using my note 4 ogrinal cables

yea.. wear and tear condition.. try replacing the USB cable (high quality).. and test it again with USB volt meter...

I've had both the adapter and the cable go bad, so you'll have to check both.

What do u meant by 'go bad' ? Do the refused to charge or charge at a very slow rate?
Sent from my SM-N910F using XDA-Developers mobile app

One adapter that would not charge at all, two cables that stopped doing fast charge but would still slow charge.
