Lots of mis information here. Im an EE and have designed many LiOn chargers.

First, that charging app everyone is using is accurate 20 percent of the time. If you want a real charge and discharge app download Battery Monitor Widget Pro.

The Note 3 charges at 5.3V for bulk charging purposes. If your N3 is plugged into the wall charger, it will charge between 1800ma and 2000ma until the battery gets to about 80%. At that time the current will slowly taper down to zero while the voltage remains constant.

USB 2.0 maxes out at 500ma. Regardless of anything else. You will see about 450ma.

USB3.0 supports 900ma max if connected with a 3.0 device. If you plug your N3 into a USB3.0 cable into your 3.0 port, you will charge at 900ma. Same deal with the taper at the end.

CAR CHARGERS. these are stupid. Even if you buy a 2amp car charger, you will more than likely not see more than 500ma. The reason for this is because in the OEM wall chargers, the 2 data wires are shorted together. (there are 4 wires in a USB cable 2 are power and 2 data). The short tells the phone that it is plugged into a wall wart and NOT a computer. Most if not all car chargers do not have this short so the phone thinks it is connected to a computer and you will charge at 500ma. There is a way to solder the inner two leads and fool the phone into thinking its plugged into a wall charger.

Basically, if you are going to use a car charger then do NOT buy the type with a USB port on it. Buy the type that has that stretchy rubber cable with the microusb connector. That type of charger WILL charge at the rated amps written on the charger. The mini USB universal style ones will not charge an S3 S4 or Note at the rated amperage.

This is fact. If youve read everything I just wrote, you wont need an app to tell you ho many miliamps you are getting. Simply look at what type of charger you are using...

Another simple way using math is to take the capacity of your battery (3200mah for the N3) and see how long it takes to charge (screen off) from say 10% to 60%. For example:

60 minus 10 is 50%. Lets say you charged that 50 percent in 60 minutes. Half of 3200 is 1600mah. You charged 1600mah in one hour so you were charging at 1600ma. If it took you 3 hours, then simply divide 1600 by 3 and you get around 500mah. Keep in mind that a 2A charger will only deliver 80%of its max rate into the battery. In other words, a 1000mah

Now that you can design them you should know it's Li-ion. LiOns are those big furry things that live in Africa.

> First, that charging app everyone is using is accurate 20 percent of the time.

And yet it manages to give the correct value in every case.

> The Note 3 charges at 5.3V for bulk charging purposes.

Not surprising given that all of the adapters are 5V.

> If your N3 is plugged into the wall charger, it will charge between 1800ma and 2000ma.

Since you're an EE you'd know that it's mA not ma and it charges at a constant 1800mA until it tapers off.

> USB 2.0 maxes out at 500ma. Regardless of anything else. You will see about 450ma.

The USB 2.0 standard is 450mA. That is why you see 450mA, less if you use one of the cheap and nasty cables you can buy on ebay.

> USB3.0 supports 900ma max if connected with a 3.0 device.

Except that it doesn't, the N3 charges at 450mA just like with USB 2.0. Try it some time.

> There is a way to solder the inner two leads and fool the phone into thinking its plugged into a wall charger.

Or you could just buy an adapter plug for $5 on ebay and save yourself the trouble.

> This is fact. If youve read everything I just wrote, you wont need an app to tell you ho many miliamps you are getting.

As many people have pointed out this is not true. The phone only charges at 1200mA when the phone is on even when the charger is capable of more. The stock charger via the MHL 2.0 adapter charges at 700mA, an MHL cable connected to an MHL 1.0 input charges at 300mA. So the app really is quite useful (not to mention proving everyone wrong who assumed USB 3.0 would charge at 900mA, myself included).

> Another simple way using math is to take the capacity of your battery (3200mah for the N3) and see how long it takes to charge.

Not true since the charging process is not 100% efficient, on the N3 it's closer to 80% so for every hour you spend charging at 1800mA you're only delivering about 1500mAh to the battery. Also the charger really does deliver 2000mA to the phone but unless the phone is powered off completely some of that current has to go to powering the phone or the phone would shut down. The total power draw can't exceed the output of the adapter so we can see then that the phone draws about 200mA (1800mA charging) in standby and 800mA (1200mA charging) when the screen is on, which seems reasonable given the rate at which the phone discharges the battery in the respective states.

Interesting! So we also can exclude that the Quickcharge 2.0 of the Snapdragon 800 is implemented. We still have to wait for special adapters to make use of that protocol.

I have note 3 sm-n900 it charges via ac adapter max 1800 when screen off and drains to 1200 when screen on..what about usb 2 and usb 3?via usb 2 450 and via usb 3 450...i think that the galaxy note 3 can't charge via usb 3 max 900.....is it phone problem,or it is pc problem?
[Galaxy Note 3 Accessories] vaheabajyan@gmail.com:
Yesterday i speak with one guy (in the forum 4pda.ru) and he says that his note 3 is charging via usb 2 port at speed- 450, and via usb 3 at speed-1000.how can it be?so i don't believe him and i say him to give me a screenshot...after 5 minutes he gives the screenshot...in the screenshot i can see that the phone is plugged in via usb (because i see the usb icon) and i see that the current is 1000...how can it be?it's like our phones, or motherboards,or pc's are deffective.?
[Galaxy Note 3 Accessories] @rbiter:
Usb3 is max 900ma. He could be fooling you with BC 1.1 which allows charging through USB up to 1.5a. I have a 4 port usb2 hub that is like that but it needs the ac adapter to charge that high. The device plugged in needs to be BC 1.1 compliant of which I am pretty sure Samsung advertised on some spec sheets for the note2. I am not sure if note 3 is BC 1.1 compliant but I think I will see if it is when I get home. And chances are it will show as ac charging but not 100% sure off the top of my head.

[Galaxy Note 3 Accessories] vaheabajyan@gmail.com:
Yes usb 3 is 900 mA.but in charging current app it will show 1000 not 900,like usb 2 which is 500 but shows 450
[Galaxy Note 3 Accessories] @rbiter:
I believe he is using a BC 1.1 hub. I tried on both my note2 and 3 and they both showed 1000ma for charging from a usb2 hub. I unplug the ac and it goes down to 450 immediately. So now you call your friend out.

Is there anyone whose phone can charge via usb 3 at the speed 900 or 1000?
[Galaxy Note 3 Accessories] @rbiter:
I haven't had luck with my usb3 hub or direct from usb3 port. My last sager laptop had one.port that would charge up to 1000mah even while laptop was off, not just standby. Had to push a button for it though. Sadly, my sager np5160 doesn't have these features. I am sure somebody will figure out the 900mah thing though I dont use my laptop for charging.

It's russisn language.if you can't know it then translate to english...here is my question--ПОЧЕМУ ТЕЛЕФОН МЕДЛЕННО ЗАРЯЖАЕТСЯ ОТ ПОРТА USB 3. ЗАРЯЖАЕТСЯ С СИЛОЙ ТОКА 500 MAH y USB 3..ВЕДЬ y USB 3 ПОРТА ОН ДОЛЖЕН ЗАРЯЖАТСЯ С СИЛОЙ TOKA 900 MAH...я уже задал этот вопрос вам и вы ответили что Вероятно, выходная сила тока разъема USB 3.0 вашего компьютера не составляет 900Ма...я спросил у производителя моего материнки-так как думал что это проблема с моей материнкой-и они ответили что-Согласно спецификации, USB 3.0 разъемы допускают подключение устройств с потребляемой силой тока до 900мА. Текуще значение силы тока определяется параметрами подключенного устойства....

And here is the answer--При корректном функционировании мобильного устройства, USB-порта ПК и при использовании оригинального USB 3.0-кабеля Самсунг, телефон должен заряжаться с силой тока 900 мА. В данном случае рекомендуем Вам обратиться в авторизованный сервисный центр компании Самсунг Электроникс, для выполнения диагностики устройства.

[Galaxy Note 3 Accessories] vaheabajyan@gmail.com:
And what it shows for you?
[Galaxy Note 3 Accessories] CraigAmey:
It's neither, the Note 3 only charges at 450mA on USB 3.0 port regardless of how much current the port is capable of supplying. The note 3 can tell if it's connected to a charger or a USB port and adjusts accordingly. You can however charge at the full 1800mA buy using an inline adapter which turns the USB port into a charge-only port.

I use a Plugable 7 port USB 3.0 hub with a 4A adapter and that's been my observation. I've been following the forum topics on this since the release of the Note 3 and I've yet to see one single case where someone got more than 450mA by just plugging a USB cable (either 2.0 or 3.0) into a USB 3.0 port.

Yes. He is saying all USB will only charge @ 450mah. I myself kinda came to this conclusion but still not sure. I am sure you dont have a problem as this is how all note 3 are acting out of the box.

It depends on the computer. My laptop has a "Power" Usb port. It definitely works, verified by Galaxy Charging Lite. (1200mAh) Note 3.

On my old Note 2 (with custom kernel) that same Usb port on my laptop would provide 1800mAh.

So, not all Usb 2.0 ports are created equal :)

http://www.ebay.com/itm/USB-Charger...e-Battery-Tester-Power-Detector-/181422395734

the different cable will give the different output.. i have testing with all the cable i have, still can find the conclusion whether it is a good or bad cable, because when 1 of the cable can deliver 1.66 A with another wall charger, but in other charger it can drop to 800 ma.

but the usb 3.0 cable can deliver the best output even with the generic usb 3.0 cable.

[Galaxy Note 3 Accessories] nexx2014:
I haven't measured my charge rate but to me my phone charges blazing fast I mean for using a 6400mah anker extended battery to charge from 5% to over 50% in like less than 30min and 50% last me a day on the extended battery stock battery is really fast for me also. Mainly which is why the new feature on the note 4 rapid charge didn't impress me lol how much faster do I need.

One thing though when I charge it that I'm not going to use it I plug it into a very short USB 3.0 wire that came with a external hard drive of mine its maybe 6 or so inch's long.

Pretty much if I forget to charge it over night I just plug in that short wire hop in the shower get dress and ready to head out and I'm close to if not fully charged by then.
[Galaxy Note 3 Accessories] ldmelo:
Samsung devices (galaxy s4, note and don't know which others) will charge faster if you use a shielded cable. In such cable the outer part of the USB male plug is connected to the other side of the cable, usually via a mesh of metal frame that surrounds the internal data cables. The phone can detect this, and the current will drop, usually to half, when the cable is inappropriate.
[Galaxy Note 3 Accessories] Kangal:
Theoretically it should be able to charge at 2,100mA, but as everyone noticed it tops out at 1,800mA.

If you use an older charger, or your laptop's USB 2.0 port it will charge even slower at 1200mA.

I have a no-name (but high-quality) USB charger that's 5.0V and 2.1 A.

It used to charge the Note 3 from 10% to 80% in about 60 minutes.... that's fast, its actually stupidly fast for something that's not a "fast charger"

Of course the Note 3 would get a little warm.

I've since stopped using my gold (thick-plated-low resistance) microUSB cable because I'm "uncoo" and keep mixing up the sides of the USB on the N3.

I've since stopped using that other charger, because I noticed some burn-marks inside the charger's usb socket.

So I'm back to stock charger and stock cable.

Now it does the usual 10% to 80% in something closer to 75 minutes.... that's above average, kinda fast

Compared to the SGS 4/Note 2.... its a good deal faster. Samsung's made some improvements in the circuitry.

And wireless charging is topping out at around 1,000mA... so even the fastest wireless chargers are about 50% slower than wired chargers.

And average wireless chargers (700mA) are about 50% slower than average wired (1,200mA) chargers.

Again nothing can hold a candle to the Oppo Find 7's VOOC.... I am so jelly

For anyone complaining about the low current reading out of your bought usb inline current readout plug, you should try this app. It's a better way of monitoring your battery charging current, and the battery's health condition as well.

Yes I've tried several. I've seen 3A on most. It varies a lot but a near dead batt will get the biggest numbers from the charger.

I have the motorola turbo charger for the droid turbo and nexus 6 too. Those go up to 12V and work great especially if you have a longer charging cord. Higher voltage will overcome line losses since the current is lower per Mr. Ohm. ;)

[Galaxy Note 3 Accessories] Kiriakos-GR:
While your multimeter this is crap, I liked allot the way that you thought so you to explore and find the truth.

Yes this never gets higher than 1200mA at this operating state of the phone.

You must realize that what you have at your hands, this is one small sized computer with out active cooling.

CPU must retain it self far from destructive temperatures, and one way to succeed it this is by under-clocking it self.

The second way this is limiting the operation of charging system to lower current output, because charging system among with the battery this is a second active heat source.

Therefore behind the product design of your phone there is some smart engineering, by the use of complex electronics, them self adjusting their functionality so overheat this to be avoided at any cost.

There is no way for you to use command line in this circuit, what you are not able to see, this is three programmed IC working together, and them be enclosed in to a single case.
