The charger looks identical to the one provided with the S4 and Note II, it's 2A after all.
However it isn't! Galaxy Charge Current Lite (in the play store) shows 1200mA when plugged into this charger.
However the charger included with the Note 3 will show 1800mA.
The difference is the output voltage. The Note 3 charger is 5.3V whereas all the others are 5.0. This slightly higher voltage can allow the phone to charge at the higher current even if your cable has a bit of voltage drop. I have not tried with other cables however.
The (Note 3) does seem a bit more sensitive to charger type and will drop down to a lower charge current faster, however.
My 10Ah Anker bank will charge at 1200mA, for example. The 2A car charger I have also charges at 1200mA.

I've noticed that the note 3 charges a whole lot slower than the note 2. It actually seems that this phone charges 1/3 slower than the note 2 which makes perfectly good sense to me considering it does charge at 1200 vs 1800. One time when i plugged my phone in while using galaxy charge current pro ( auto refresh checked ) it clearly read that it was charging at 1800. My phone charged really fast. It only happened once though. I've used other chargers with the oem cord and other chargers with other types of usb cords. It doesn't matter what combination I use I still get 1200. Maybe it's something limited at the kernel level....
I saw this strange behavior connected the phone to my pc with the original cable in usb3, 2 times it charged with 1800 but most times is going to 1200 and I haven't understand why this is happening yet.

OK not sure if galaxy charging current lite is reading correctly. I plugged in an old iphone "block" style charger, connected a non USB 3.0 cable and it said 1800mA! It dropped to 1200 when I refreshed it.
Plugged in the included USB 3.0 cable and 5.3V charger and it did the same. So not so sure about this.
However with 5.3V the phone should be less sensitive to cable length. Look out, 10 foot cable here I come! :laugh:
Ehh not true because on my note 2 it said 1800 with the note 2 charger. It depends how much stuff is plugged into that socket. And to others who say their note 3 charges slower, mine charges faster. If it is plugged in by itself and not have several electronic devices plugged into the wall.

Indeed as what the title suggests. Mine charges from 0 to 100% within 2 hours and 15 minutes (compared to 3 hours on my S3).

Nah because downstairs in my house my note would charge at 1400 with several equipment attached. And upstairs in my room with nothing on a wall socket it was doing 1800.
Downstairs took 3 Hours to charge phone, upstairs took 2 hours and 30 to 45 minutes to charge from 0%.

I have innergie 3A shared USB charger and it charges Note 2 and Note 3 pretty quickly (usually within 2 hours), but I found the phone gets rather warm if I use this charger, so I'd stay same and use a bit lower current.
Kensington Absolute Power can charge Note 3 quickly with 2A out.
Indeed, shorter (with lower voltage drop) and thicker (allows more current) USB cable also helps.

The chargers are SMPS (switching mode power supply) and can provide +5.3V @ 2.0A continuously with an input source between 85V and 250V 50-60Hz. I would not be surprised if you could put 10 car batteries in series for 125VDC and that would work the charger as well. Many SMPS can use DC too. NEVER connect that directly to the phone, you will have explosive charging indeed.
If your line voltage from the wall is dropping below 85V you have a serious issue that should be checked by an electrician! (or have way too many phones charging)
Well it doesn't affect my daily life or other electronics. So I'm good and don't need hire an electrician lol.

Billiy is correct. As an electrical engineer, the only way you would have voltage loss is if your house wiring was incorrectly installed as series. In that case, you have bigger issues than how fast the phone charges. Wired parallel there will be no voltage drop. So there definitely was an outside factor in your results with upstairs vs downstairs.
I used same charger and cable. Look all I'm saying the only benefit of USB 3.0 is if you're using to charge through a laptop or PC through a usb 3.0 port. Because through the charger it's only delivering 2 amps regardless of usb 2 or 3.

I saw your video and afterwards I'm still not convinced. Neither is my co-worker who also had a note 2 and now has a note 3. I was using my friends charger from the s4 ( the 2 amp samsung one that looks identical to the note 2 ) and it was charging my note 2 slower than normal. So I pulled out the galaxy charge current and his charger was only charging at half the rate and would fluctuate big time if I moved the cable. So Without you running that app or proving somehow that this phone is charging at a certain current vs another one at a certain rate then this test could be counted invalid...
My phone only shows 1800 if i first unlock it.
Else, it shows 1200 sometimes 1250. Does that mean it cant charge at 1800 when the screen is on?
CHarging is good but the battery is not good
the note 2 have 3100 mAH and NOte 3 had 3200.. i wish samsung will upgrade the battery more than 3200 mAH..

So I went on a 2 hour trip using my EVO as a gps. I had it plugged into the car charger the entire time. Little did I know the EVO was using the battery faster than it was charging. I've done this many times with the EVO 4G with no problems. Any suggestions? The phone is basically useless as a gps for any long distance trips. The battery will never last.

get current widget, it tell you how fast your phone is charging, and when unplug how fast your phone is draining in mah, note your mah usage when unplug, then note your mah usage when battery is fairly low and plugged in to charge with the car charger.
if your battery is low (below 50%) and your phone still won't charge faster than 500mah on the car charger, it will not keep up with GPS uses, be aware that as the battery approach full, it charges slower and slower, near 97~99% it will only charge @ about 100mah rate.
I bet you have a cheapy car charger that only supply 500 mAmp, get one that can supply 1000 to 2000 mAmp (1A to 2A... 2A usually for DUAL usb outlet type charger)

I've never had a problem using this older but more powerful iGo AutoPower 3000 car charger. Overstock has them for $6.50+shipping and you get a bunch of power tips with it but not a microUSB tip.
http://www.overstock.com/Electronics/iGo-AutoPower-3000-Car-Charger-Power-Adapter/3668307/product.html
The power specs on the package I have say:
DC Input: 11.5-16 VDC
Power Output: Up to 15 Watts continuous
Radio Shack sells the iGo a97 tip for $10+taxes but Amazon has the tip for $6+shipping(free shipping if you have prime).
http://www.amazon.com/iGo-Kindle-Motorola-RAZR2-KRAZR2/dp/B0012J52OC/ref=sr_1_1?ie=UTF8&qid=1310316568&sr=8-1
From my understanding, the tips have a resister in them which limits the mAmp output but I'm not sure what the a97 tip specs are since iGo doesn't seem to release that info. Hopefully it's 1A like the wall charger. I can verify that the newer single output iGo chargers are limited to .75A. So even if the tip is 1A, the charger is the limiting factor, hence why I recommend the older, more powerful one.

Read the label on the charger, make sure it say at least 1A or even better 2A
lots of cheapy dual USB on ebay that's not rated for 2A
if you got a 2A charger and current widget still show 500ma charge rate,
then you may have to figure out if your phone is charging in USB charge mode with the car charge (limit to 500ma by the phone per USB spec) or in AC charge mode (charge at up to 1A)
I just came across this other day that point out this problem.
http://www.amazon.com/gp/customer-m...B9U8Q/ref=cm_ciu_pdp_images_3?ie=UTF8&index=3
look at the mouse over box comment... of course every charger is different so don't just blindly do the mod if you have a different charger.
as for the other guy asking for 2A charger....
Ebay and Amazon have alot, just make sure they specificly say 1A for single USB or 2A for dual USB output.
for 2A dual USB, the OEM HTC thunderbolt one seem to be the best but also most pricey, some alternative are the Motorola dual usb and the Tmobile my touch 4g dual USB

Was having the same issue;
I used the car charger I had for my EVO, left it on for 3+ hrs, with little to no increase from where I put it on at. Ended up using a buddy of mine sharger and viola. Imex99 explained the reason for it. Just buy a new charger with 1A/2A output rating and you'll be good.
I'm having the same issues. I click enable usb charging and then commit, but it keeps reverting back to disabled with no difference in charging capability.
Speaking of car charging, why does the battery temperature vary so much between AC & USB, versus Car charging?
With the supplied HTC AC charger or USB connected to a computer, the battery's charging voltage is 4.333 volts and the temperature is 81*F.
With a Sprint Car Charger, the charging voltage is 4.333 volts but the temperature is 95.5*F
Even chargers rated at 1A/2A may not have the appropriate pins soldered together to enable 1amp charging. Please see this thread I made when I had the Evo 4G:

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.

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.

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

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.

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.

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.
I bought an Xtreme 2.1 amp car charger but I noticed once charged my note 3 gets hot (110 F when I unplugged it).
Would using the oem cable be likely to help? The Motorola USB to micro plug cable I used did not cause overheating on an ac plug.
Can you suggest a car charger that works well without causing the phone to get hot?

The official samsung car charger works very good for me.

Ah, no samsung stores here. Verizon carries there own not samsung. On eBay and Amazon terrible reviews so not sure it is oem even though they say it is. Do you know the model number you have?

Car Charger
Hi I am using this for car charging. USB outpu is coded for samsung so it can charge with full capacity (as wall charger)
http://dx.com/p/dual-usb-3-1a-car-c...-mini-samsung-p1000-black-171789#.UuV45NJajIU
Electronics in it has very high coversition efficiency (%95 effc. 14V to 5V conversition) so it will not heat up.
Two independent ports one 1A and other 2.1A
Wish helps,

ST Microelectronics L6910 and variants
It uses cheap but efficient STMicroelectronic chips,
So it is not a crap at the moment. But it can vary batch to batch on DX as always.
You seem to know a lot about electronics. Does the cable I use matter or is the charger primarily responsible for overheating?

1- if charger has low efficiency the loosed energy will turn to heat on charger. Generally efficiency is near 80% and it translate to near 2~3watt energy loose on full power. It will heat this little chargers very fast.
2- if the cable is too thin or connectors oxided, power loose on cable will heat cable, charger also phone. If the problem is cable charge time will decrease when cable heated. So if your charge time is ok, problem is dc-dc convertion efficiency.
You mention low efficiency getting charger hot. It wasn't., nor was the cable. Only the phone was hot.

chargers output voltage and ripple must be measured.
Voltage higher than 5.5V or voltage ripple can cause this. Charger voltage can ripple from 4V to 6V and you can only measure 5V avarage voltage with standart multimeters. Be carefull and do not use that charger.
Im using this one from Verizon. It works very well and has a handy led light

Anker® Dual Port USB 18W Car Charger
I just bought this one from Anker. http://amzn.com/B00DDLYCUW
Ran my n3 with gps, spotify, OutLoud reading my texts, all while driving and it was charging up, not draining.
Anker is a good company, Amazon is a good company, and you can't go wrong for $8.

That's what I use and it's AWESOME!! It's got a 1 Amp port and 2.1 Amp port. Also, you get 2 in the package, one in white and one in black! Best deal online, not to mention the best charger I've used!!

You can try this?
I have a 2010 Mercedes c class and needed one that wouldn't stick out too much so I can shut the ash tray cover and this works well and charges 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%

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/
