^^ what he said. 5v and 2.0amps is like double the normal chargers... 2.0amp is crazy fast... from 32% to full in just under an hour
Yup I bought an extra one on Amazon because of how slow my old charger charges it. It's like trying to charge a laptop with a phone charger haha you need the more powerful charger. My car charger claims its 1amp too but I feel like it charges super fast too.

I have the same prob. Charged about 7% in 30 mins (using the supplied charger). Charges fine when I use my N7 charger though. I'm gonna have to check the charger when I get home.
Just for the hell of it, here is my how my charge is going right now:
7% - plugged in at 3:22
21% - 3:31
33% - 3:42
44% - 3:52
57% - 4:04
83% - 4:28
For what its worth I don't have this issue with charging - s4 charges comparable to s3 HOWEVER i am not using stock charging that came with the box, I am using cables i have had from before and sometimes even use the USB to wall plugs from Apple and/or BB or whatever I have had lying around - seems to work well.
With a 5V 2 amp charger it goes like a bat out of he'll, using my thunderbolt's 5V 1 amp charger it's quite slow.
Sent from my SCH-I545 using xda premium
i have noticed that having it plugged into either a car charger or a computer, it does NOT charge very quickly... not to the point where it is annoying but, slow enough to notice a difference...
If i take the cable from the box and plug it into my USB hub (it has it's own power source also) if im using it for much other then file transfers i can still lose power off battery. It just seems to slow the battery drain instead of just charging slower then plugged into the wall with the 5V 2amp plug. Now obviously if I'm not doing much with the phone while on the USB it will charge but much slower then the wall charging

Sent from my SCH-I545 using Tapatalk 2
Ok, there's something else going on here. Maybe its software related.
My S4 will only charge fast on the supplied charger. The cable doesn't seem to matter; I tested a bunch of them. I have an assortment of other 2A chargers and none do better then barely keeping up with power useage; hardly any charging at all. Again, the usb cord doesn't seem to make any difference.
Now, I've read mention of a "fast charge" feature that the kernel developers are "turning on". I haven't found a good explanation of what exactly that means but it appears to me that Samsung tried to make the device only charge at the full rate using their chargers and at a minimal trickle charge rate for all others even if they are capable of the full 2A output.
Then there is the problem of buying extra Samsung chargers since there appear to be a lot of knock-offs that will not get the phone to charge at full rate.
What a stupid thing to be such a PITA.
Anyone have any solid info on this?
just about every samsumg device either needs a kernel hack or an adapter to get fast charge off of a non-samsung charger. you can grab a few of these:
http://dx.com/p/usb-data-charging-extension-cable-for-samsung-p1000-black-91141
and use them with just about any 2amp charger with no problems on my old galaxy tablets or my galaxy note and nexus getting fast charge(nexus even charges faster on the 2amp - hope i don't blow it up!).
Fast charge from my understanding is just turning off the data connection when plugged into a computer. This allows for higher usb charge rates, it also helps certain wireless charging setups. I am coming from a gnex where this was the terminology, I assume it's similar. Fast charge shouldn't do much for you if you are having trouble with 2amp chargers, but maybe in this case Samsung limits through put when it doesn't recognize the charging unit? If fast charge tweaks somehow disable this, then I guess it's possible you would enjoy increase in charge rate though I have no verification on that.

There's a problem with semantics going on. Fast charge is exactly what you're used to it being on the GN. What's being referenced here is quick charge, a feature of later Snapdragon SoC's.
Sent from my Nexus 7 using Tapatalk HD
fast charging is rapid charge where near full power is transferred. in the gn2, gnote 10.1, gnex, and gtab10.1 the max i got was ~1600mA with all my 2.1A chargers including the samsung charger. the rapid charge continues to 90% and then switches to trickle - anywhere from 400-900mA til 100%. without the adapter you're stuck at trickle, even at under 90%. some chargers seem to have it built in to rapid charge,but most don't.
i've never gotten a full 2100mA from any charger yet.
you can find schematics on how to build your own adapter in one of these samsung boards. i think there was a very detailed one in the gnote10.1 forum.

The beast? I got mine but haven't powered it up yet for charging purposes. There is no light indicator that tells you when its done.
Got mine yesterday and I charged via AC and it took about 3 hours to complete. After letting it drain over night after 8 hours of heavy usage, I'm charging via USB and it's taking forever. With it on and after 2 hours, it was only at 15%. Now turned it off and it's been 3 hours and it looks like 75%. BTW, press the power button once and the screen will show the batter gauge.
you should charge it while turned on and for 6 hours or more for 4-5 cycles. Let it go down to 5% for those 4-5 cycles. Do not let it turn off from lack of power.
That is from instructions I received from a third party battery which had these detailed instruction to maximize capacity. I am sure you will get 1000 different ways but that is what I use and have always had good battery life.

This thing pretty much requires the cable that came with it to charge at full speed. Older MicroUSB cables charge at a much slower rate and are recognized as USB devices when plugged in. It must be because of the higher capacity battery. When you have the right cable plugged in, though, it charges pretty fast.
I'm noticing that even using the wall charger and the USB cable it came with, it's taking about an hour for the Note to charge only 15%. Anyone else noticing this? Is it normal that the first batch of charges takes this long (at that rate it would take 6+ hours to charge from 0-100%)?
My note charges very fast when I use the ac adapter and super slow when I use the us from my computer. About 1.5 hours on the ac and more than 3 hours on my pc's us
Sent from my SAMSUNG-SGH-I717 using XDA App
Its always a good idea to charge using the AC wall adapter. The USB port on a computer usually supplies ~.5A @ 5v to charge the phone, the included Samsung wall charger supplies double that with 1.0A @ 5v. That is the reason you see such a big difference in your charging times.
(Some computers now supply more than .5A through USB, but .5A is most common)
USB3.0 can supply 5.0v @ 950mA to charge, but the kernel isn't set up to take advantage of this, I'll see if I can change that (it would only affect charging while booted)
Just shy of the AC adapter for those of us with USB3 ports

The charger that comes with the Note can charge the battery in 3hours via ac. I wouldn't suggest to charge via usb, just because it's way too slow. Im using my playbook charger to charge my Note, Galaxy Nexus , and my bb 9900. This charger is 1.8a, it nearly charges 2x faster than the regular 1a that comes with most phones. Same thing for my car charger 2a, i even use my ipad charger to charge my iphone 4s and it's way faster!! Use more powerful chargers... Not more than 2a or your device might melt down!!

That's weird. I was under the impression that GS Note only accepts 1.0A of power. Well at least that's what it saids at the back of the phone. I've got an iPad charger that draws out 2.1A, maybe I should give that a try.
So I will get the regular charger for gs3 that comes with the phone (tomorrow when i get the phone). but i also have the HP Touchpad charger which gives output of 2.0A. I was wondering if I charge my phone with the HP charger will it actually charge is faster then the regular gs3 charger? the reason i ask is cause in other threads ppl have mentioned that it only charges faster with non - stock roms like aokp or aosp roms. please lemme know if this will work. thanks

A lot of chargers will be rated less than the stock charger. Especially cheap car chargers. In that case the phone can only draw at the charger rating.

The values listed on the charger is the max output it can provide. If the setting on the phone or the hardware is set up to only pull 1A, then it will always pull that unless that is more than what the charger can provide.
That being said, you should be able to take the battery out and charge it faster separate from the phone. I've always read, though, that charging a battery faster ( i.e. turning up the current) will/may reduce the life of the battery

I have a Touchpad charger and it can be used, though I noticed that the phone got hotter than normal, IMO. The phone comes with a 1.0A combo wall charger with USB cable. Interestingly the Samsung stand and battery charger that comes with the spare battery comes with a .7A charger but the charging unit itself is 500mA/1A on the input with output at only 4.2v @ 450/900mA.
Wondering if anyone has tried it? I remember reading that the wall charger from my Tab 10.1 was more powerful than for the phones because it would take FOREVER to charge. Wonder if it's compatible with our S3?
Anyone?
I believe that anything that charges on USB is just getting 5 vt, so any charger would work with any phone/tab if it is charging through USB. I would guess that the wall chargers are also putting out 5vt and would therefor be fine with any mini USB plug charging device.
Easy to check, plug it in and see how it works. (Buy insurance first )

Any modern device will limit its own current draw to what is needed to do the job. While it is certainly possible for a charger to be underpowered resulting in slower charging it should not be possible for a charger to be overpowered. That is, there is some maximum charge speed the phone is capable of and that limit is expressed as its maximum mA draw. a charger that sources under the max mA will be slower than one that meets or exceeds it. A charger that exceeds the max mA will not charge any faster than any other charger that also exceeds the device's max mA regardless of the differences in their source capacity.
So, if that makes sense to you then you should know it ought to be safe to use a powerful charger and that if faster charging results then the stock charger is in fact underpowered for the device it was paired with.
Disclaimer: Any engineer worth his salt is going to current limit the charging circuit on the phone. However, if this were not the case then providing increased charging capacity will most certainly damage the device.

The Fast Charge mode on the KT kernel has no impact on AC charge rate, it only affects USB charge rate:
Normally, when you connect to a PC, you get about a 500ma charge rate and the ability to pass data along. When 'Fast Charge' is set, you lose the ability to transfer data, but the 500ma restriction goes away. In practical terms, it means that you should see between 700ma and 900ma as a result.
w/respect to the OP, my experience is weird. When the device was new, I got around 1800ma on stock charger and cable; now, same setup gets me 900-1200 if lucky (even with new battery). When I tried the stock charger with a different (newer) cable, I get around 1600. It's strange that a cable's ability to carry a charge would degrade so quickly (if that's in fact what's happening).
I have no proof, but absolutely believe that kernel can influence max charge rate, because in the past, I've observed max charge rate drop with the release of a new kernel version, then go up again with another release.
Samsung did slow the charging rate in one of the OTAs. People had been complaining about the phones getting too hot.

What are you using to measure that? Qi isn't capable of charging at 1.9a
The galaxy charging current app..
So you've noticed that sometimes your phone seems to take forever to charge, and other times it seems to charge fine? Let me share some ideas that I've learned through lots of research on this exact subject last year...
I have used the galaxy charging app myself. In my opinion, CurrentWidget is better...looks cooler too. Ha.
So other than software related issues, you need to remember that the speed in which your phone charges is highly dependent on the hardware of 3 things:
1) Power Outlet (including power strips, extension cords, USB extenders, etc.)
2) Power Adapter (I highly recommend Anker's products!!!)
3) MicroUSB Charger Cable (if not using the factory Samsung cable or an Anker one, be sure that it's an 11-pin microUSB, and NOT a 5-pin...they look the same!)
Power Outlets - I know for me, if I use the outlet in my livingroom, it takes SO much longer for my phone to charge than it does in my bedroom. Just try this test! Grab that CurrentWidget app from above and try out some different outlets throughout your house, just to see whether or not the voltage varies. I bet you'll see that this is true!
Power Adapter - You should be using either the factory Samsung charger or a reputable 3rd party charger with the equivalent specifications (5V & 2.1A). However, I actually prefer my Anker charger over my Samsung one! If you're finding that you can't get a good charge, try swapping out your adapter with another one.
MicroUSB Charger Cable - As stated with the power adapter, you should also try to stick with your factory cable if possible. HOWEVER, I have found that to daily connecting and disconnecting of the cable with your phone, they probably receive the most wear and tear of anything else, and therefore may need replacement after some time. Again here, I find that using either my Anker cable or Samsung cable will give me the best charge. This is determined by both the CurrentWidget app and the amount of time it actually takes to get a full charge! Keep in mind that using USB extender cables can drastically lower the voltage to your phone - thus causing a very slow charge.
So basically, I know if I need to charge my phone as quickly as possible, I know I should clear my RAM and recent apps, put my phone on airplain mode, and using my Anker charger, I plug-in at the outlet near my closet door! I figured this all out by using these same ideas I just shared with you! Hope this is helpful!
If you can tell the difference between outlets, you need to call an electrician. Not kidding.

I doubt that's entirely true. I mean, think of if they're on different circuits, that kind of thing can vary...also, depending on what you have plugged into your outlets can cause lower outputs I'd assume. I'd bet if you used the app I referred to and ran a test at each of your outlets, and reported back here (being honest of course), that you'd see some differences. Anyways, that was far from the point of the post. But thanks for the insight!

The Samsung power supply is rated for 100 to 240 V @ 0.5 A input. It may be that the power supply is kind of crappy, and varies its output under small variations in input voltage, which is why you see what you see. It really shouldn't...but it wouldn't shock me if it did given that its made for $2 in China. Makes you wonder what would happen if you plugged it into a 240V source. When my wife went to Malaysia last summer to visit her folks, I just put a US to British transformer-less adapter on her Motorola brick and it worked OK plugged into 240V. Maybe the Samsung ones are crappier?
I squared R losses should be reasonably low in household wiring. NEC is 5% drop max at the outlet. And that is like the outlet the farthest from your mains under full rated load. Assuming you live somewhere typical, your voltage at the panel will be 120V+; a lot of time its a few volts over 120. If you have an outlet that is not tripping a breaker go below 100V, you have a problem somewhere. A 20% drop is not normal. Have you put a meter on the outlets with low charge rates?
My friend's OEM s4 charger charges at 1900 ma while my OEM charger only charges at max 1200... Weird how that happens but somehow the cable just stops charging as fast.

I'm rocking the zero lemon battery and since I've bought plenty of chargers and none seem to fix my slow charging problems is there any wireless chargers? Will me using the zero lemon battery not allow me to use a wireless? Also if all this is fine, does anyone have any recommendations??

Even though you can try to use that battery with wireless charging it won't fix your slow charging rate. Wireless charging goes max to 0.6 A (600 ma) when it comes to charging. So it's 1/3 the speed of your regular wall socket charger.

When I say slow charging I mean it comes up on my screen saying charge it with the cards given. It charges about 30% in about 9-10 hours.

Something is wrong with your charger or cable then. My ZL charged from ~78%-100% in about an hour last night. The plug adapter that came with the phone and a USB cable I've used for a while, from a Nook I think. Wireless will be VERY slow. It's fine for topping off, but if you drain it down you will want to use a wired charger. You can use a wireless charger with the ZL, there's some info in one of the threads talking about what you need to order. You can't use the contacts on the back of the phone for it, you need to use one of the low profile USB plug type.
If you want fast charging you need to use the adapter that came with your phone, or another known good adapter, and a good quality USB cable. It doesn't have to be USB3, a USB2 cable will work fine, but it needs to be good quality. Monoprice is a good place for inexpensive, but good quality cables.
If you are connecting to a computer USB port, you will charge slow unless it's a USB3 with a USB3 cable.

I've bought a couple chargers on eBay and they said it was OEM, but neither have worked. One was a Motorola and the other was one specifically made for the Note 3, or so it said.

Didn't you get one in the box your phone came in? Try that one. Like batteries, chargers are often fake and don't meet the specs they list.

Try a usb 2.0 cable to charge it.
The little extra part for the 3.0 seems to have gone bad in my phone after only 4 months.
If I charge it with the cable that came with it, I have the results you are saying.
If I charge it with a 3 year old usb 2.0 style charger, it charges fine.
Good luck!
Get a usb voltage/current tester. They are like $10. You can test all your chargers and cords and find the under performers.
My phone with zerolemon charges fast with the original samsung charger, and my Asus t100 charger. Fast being relative, from 20% to full it can take 4 hours or so. I've never timed it 100%

Does your battery seem to die quicker right after you unplug it?

Yes, it drops to 97% straight away. This is because it drains in the background a little as the charger doesn't trickle charge. See this for an explanation http://www.androidpolice.com/2010/1...bump-charging-and-inconsistent-battery-drain/
