Couldn't find an answer to this after searching, so here's my question.
If I use, say the micro usb cable from the Note 2 to charge my Note 3, will it be as fast as using the Note 3's cable.
The note 3's cable is USB 3.0 which I understand would make data transfer faster (assuming PC has USB 3) but there's conflicting info about whether this makes charging faster.
For the sake of above, assume the power source is the same (i.e., a wall charger).
Does anyone know or has tested?
Cheers
Mine charges just as fast using normal USB 2 cable add it does the 3. USB 3 is higher data throughput. Not amperage. That is off the charger itself. I never use the 3.0 cable. I use 6ft USB 2 cables and still charge in about two hours, little less usually . It's all about the output on your charger. 2A like the stock one or Verizon ones and you are fine. 500mAh charger would take forever to charge it though.

I actually notice a difference or I'm not sure if it's in my mind but a hour and my battery is fully charged with supplied charger my old note 2 charger take 1.5 or so hours to charge.

Now I'm not sure about subtle details on how usb charging works, but it seems the original wall adapter is not outfitted with a usb 3.0 port. If you look at usb 3.0 ports (female end) they have metal contacts on the front edge, which the samsung wall adapter doesn't have. Not sure if the extra contacts carry current, but my guess is if only the standard usb 2.0 contacts are being used then speeds would be equal regardless if a 3.0 or 2.0 cord is used.
I have USB 2.0 cables that charge just as fast as the supplied USB 3.0 one. I also have ones that don't.
Don't buy really cheap cables. cheap ones usually have thinner copper wires (the cable could still be thick, but that's down to thicker insulation). If there's not enough copper to allow the current to pass, the charge rate will be slower.
I believe the USB 3.0 cable only charges faster if plugged into a USB 3.0 port on a computer compared to a USB 2.0 cable. On a wall charger they are the same speed.
Wish there was an app like Galaxy Charging Current that would work on this device.

USB 3.0 spec shows 900mA so I suspect that connecting to a USB 3.0 port on a computer isn't going to charge as fast as the 2A wall charger over either USB 2.0 or 3.0 cable. The big difference should be in data transfer. I never charge my Note 3 over USB 3.0 cable, always the 2.0 cables that I have all over the place. Strange thing is that it charges consistently faster than my Galaxy Nexus on the same cable/charger.

Galaxy charging current lite works fine for me. The cable makes no difference at all. Good quality cables should charge at 1800mA from the charger regardless of whether they are USB 2.0 or 3.0. This translates to a little over 2 hours charge time.
From a USB port either cable will only see 450mA unless you insert an inline adapter designed to make the note think it is connected to a Galaxy charger.

Just uninstalled and -reinstalled the app, now it's working. coo
How is the current for charging detected?
Differenc in charging time depends on a higher charging current.
The current of 500 mA for USB 2.0 and 900 mA USB 3.0 to my knowledge only for the Device = Note supplying power to external Devices like USB-Sticks (e.g. Memory or DVB-T), Hardrives and so on. It does not specify in regard to using a USB plug as charger nor the the current it charges the notes with. I am wondering how the current detection between the original Galaxy or Nexus charger and any other charger, USB-Hub or computer port is done.
When you compare µUSB-B 2.0 to 3.0 connection http://en.wikipedia.org/wiki/USB_2.0#2.0 and here http://en.wikipedia.org/wiki/USB_3.0 youls find that the USB 2.0 µUSB-B has the same connection as the µUSB-B 2.0 (note http://en.wikipedia.org/wiki/USB_3.0identifies 11 Pins for µUSB-B which seems incorrect because Pin 5 has to be ground to be backwards compatible).
The additional 5 Pins are only for the 4 USB 3.0 Data-Lines and ground.
If you look into the USB-A connector in the charger you'll see also only 4 Pins like in any other female USB-A 2.0 connector, so using a µUSB-B 3.0 can't be the reason.
I'll edit this as I have more things to test. All using Galaxy Charging Current Lite app
Charging current:
OEM USB 3.0 cable + wall charger = 1200
OEM USB 3.0 cable on PC USB 2.0 port = 450
Monoprice USB 2.0 cable + OEM samsung wall charger = 1200
Monoprice USB 2.0 cable on PC USB 2.0 port = 450
Mine charges faster with the stock USB 3.0 cable. This is incredibly fast compared to the Note 2 charging cycle.

OK here are myvalues Charging Current Lite app displayed charging current:
Samsung USB 3.0 cable with
Samsung wall charger = 1200
USB 3.0 10 port Hub-charging port = 1200
USB 3.0 10 port Hub = 450
USB 3.0 Elitebook 8560 = 450
USB 3.0 Cable with USB-A 3.0 to µUSB-B Adaper = 1200
So it's not the cable that makes the difference.

I'm getting similar results.
USB2.0 cables same as USB3.0 cables as far as charging goes.
Also regardless of plugging into USB3.0 port or USB 2.0 port on computer, still pulling only 450.
Using OEM samsung 3.0 cable, and amazon 3.0 cable.
OEM samsung 2.0 cable, monoprice 2.0 cable.
Oh, and it will charge at 1800 using both a USB 2.0 and 3.0 if the screen is off (turn screen off, plug charger in, turn screen on open galaxy charging current lite and it will display 1800 until refreshed).
I had the time to check the AC consumption of both the Note 2 and Note 3 PS, both are with the Note off ~11 W independent of cable used.
When the battery was fully charged at 100% and the power consumption was arround 6 W, I started the Current Lite app and it displayed a charging current of 1200 mAh even so the battery was charged? Something is wrong with the displayed value if the battery is fully charged, unless it's supposed to be only the current supplied to the Note. Then why does it not correlate to the AC-power meassured?
I looked at the voltage of the Note 3 PS and noted it's 5.3V while the Note 2 PS is the standard 5 V.
If I find time i will built an adapter and check if the voltage is true DC or if there is some other signal imposed.
Or do the Notes PS initiate some kind of data transfer to let the Notes know its the original charger that can supply higher current.
Any ideas or input.
Isn't snapdragon 800 on the note 3 suppose to have some sort of quick charging feature, that when used with the factory cables should increase charging speeds?
I could detect at best a few 100 Mw difference difference between charging with the OEM cable and any other USB 2.0 or 3.0 cable with µUSB adapter or when I used an adapter to µUSB.
Car Charger
Sorry, but I can't seem to find the right answer.
I need to charge my phone whilst being used in my aircraft.
Using a USB 2.0 cable on the Note 3 supplied charger, I only get 450mA.
Will it charge faster if I install a 2A car charger in my aircraft and use a USB 3.0 Note 3 cable?
Regards,
Erich
I use a 2 Amp charger in my spaceship and it can be used to monitor the ecu while still providing enough power for the phone to charge.
You just need to be sure that the charger actually deliver 2 Amp and not 500mah

I've contrived to lose my USB-C charger so was wondering if any regular 10W 2A charger will suffice if I use a proper USB-C to USB-A cable (56k ohms)?
I used today a battery pack to charge the Moto Z.
5V at nearly 2A and it was fast enough.
So I think that it works pretty good.
I used several 10w chargers with a proper cable and charged pretty fast. But I also noticed that the plugs overheat.
Type C charger that gives turbo charging

I got CHOETECH 5V/3A 15W Type-C Wall Charger for $14.99 from Amazon and Moto Z reports Turbo Charging with it. It comes with a C to C cable.
What's the fastest charger I can get other than the warp charger?
I checked and here are my options:
Anker PD charger with USB C to USB C cable
Anker PowerIQ with USB c to USB 3
Since Warp charge is achieved with 5V 6A, which is unique, no other charger I could find supports it. PD gives 5V 3A which gives 15W. One of those has 20V 1,5 A, but I dont know if that would initiate warp. mine AUKEY 56W USB-C Charger tops at 4V 2A.

This is the 100W Baseus deskop charger and I have two issues with it:
1. When two USB C ports are used, the power division is C1=65W and C2=30W. So C1 should still be more than capable enough to handle SFC 2.0 45W charging. But as you can see in the video, SFC 2.0 is not working when two USB C ports are used.
2. When I charge at SFC 2.0 and SFC 1.0 with the same charger, they both cap at 33W. I thought SFC 1.0 is just 25W? When I use the official 25W Samsung SFC 1.0 charger, it just caps off at 24W as expected.
Baseus support sucks big time so I'm having a problem reporting this to them.

Baseus GaN5 Pro 65 watt can charge at 50watt peak.
after 60 percent,watt same as samsung 25 watt charger.
But your measurement is input power to the charger and not output power to the phone. There's a bit of a difference because of power adapter efficiency. I don't know what is the difference between the Gan5 Pro 65W and this 100W adapter really.
BUMP! Anyone please?
This is normal for such a charger. I have a PZOZ version - 65W GaN 2xUSB C + 1xUSB A. SFC 2.0 works only with 1 device plugged in, if you plug another (it might be a 5W one) - this breaks the SFC. I can assume that this is coming from the controller and the device is actually not capable to support such scenario, even though the power is declared as 100W.
Hmmm, that's interesting. I thought the issue was isolated to BaseUS. Their support is really non-existent. They reply but it's like you're talking to a stupid person that does not understand the issue.
Aside from this issue, do you have any other issues when using both ports? As for me, when I charge my phone while my laptop is plugged in, it sometimes drops the wattage on the laptop device to just 19w. If the laptop is plugged in by itself, it goes up to 59w. Not sure what's going on here.
Are there any usb c car chargers that support sfc 2.0?

But I bought the 65W charger and BaseUS said that it can only do PPS 18W.
S23 Ultra requires 10v 4.5 amp to achieve 45 w charging . Charger and Cable both should be capable of 5 amp current capacity and Charger should support PD 3.0 with PPS at 5 amp that is the basic requirement, Cable should have a e-marker chip to identify it as having 5 amp capacity to the charger. usually such cables have 5 amp written on the USB C port and are visibly thicker than the normal 3 amp cables .

Do you have any reference for that 10V 4.5A information? Some say it's 9V 5A but I never saw any official claims from Samsung regarding that too. I have no issues with cables. I'm using 100W BaseUS cables with e-marker chips on them. They don't have the 5A writing on them but they are obviously thicker than the included Samsung cable (which is only for 25W charging). Here are the specs of the 100W BaseUS desktop charger that I have:
As you can see, it does support PD3.0. Although PPS is not written there, it does support it as well as confirmed by BaseUS support and the video that I showed. I don't see 10V anywhere though so I'm not sure how it works with PPS or something. Does PPS adjust the voltage with fine adjustments or something? Also, that doesn't explain the issue I'm having where SFC 2.0 won't work when two USB ports are used. It only works when the phone is charged alone and this defeats the purpose of buying a multi-port charger in the first place.
Go to settings, about phone , and then status information the last entry there is Rated 10 V 4.5 Amp . Yes pps adjusts voltage with fine adjustment of 20mv . It can provide between 3.3 V to 21 V at upto 5 Amp . Your problem seems to be related to the charger itself which is unable to deliver the required power when two usb ports are used . BTW you can use an app called accubattery which should give you the exact charging data for your phone.

Ok, I see that now. Well, @Stenlius replied to this thread and says that this is normal. Any comments on that?
What's more weird though is that when it's charging at sfc 2.0, the cable only shows 33w. When I plug in another device in the charger, it renegotiates to sfc 1.0 but still at 33w!
When I use the official 25w samsung charger with the same cable, it goes down to 24w as expected.
SFC 2.0 - So far I have only seen with the Samsung official chargers. I've spent so much money on Belkin, Baseus, UGreen, Anker accessories and never been able to get peak speeds.

Never had the tools to measure the wattage output.
I just plug and wait for SFC 2.0 to show up, and if it doesn't - I just get rid of it.

Max anything other than samsung genuine chargers can go up to is "Fast Charging" or super charging 1.0.
