To get the s5 to take advantage of fast charge do you just need to have your cable plugged into a USB 3.0 port on pc? Or do you have to have a "system" you buy as an accessory?
And how is this compared to just the Samsung oem charger that comes with the phone? With the USB 3.0 cable.

I believe typical usb charging on a pc is equivalent to 450mA, and if you enable usb 3.0 mode you can get 900mA, and it will stay at 900 even after your phone turns off usb 3.0 after a timeout period for lack of data transfer use. The S5 comes with a 2,000mA wall charger, so it'll charge much faster that way. That's my understanding anyway fwiw.

Hi. I have USB 3.0 port in my computer. I would like to know if I have advantages if I recharge my phone on USB 3.0 port?
I will have problem in my cellphone if I make this?
No, the USB port goes into 2.0 mode.

The only advantage is, that you could transfer more energy, because usb 3.0 supports more than 500mA.
A normal charging adapter can load your smartphone with 1A.
But it is possible, that you have to use a standard loading cable (whitout data).
Perhaps with a kernel with this modification in it you might be able to pull the 1A like the charging adapter...just an idea though, not tested...
Perhaps I'm not understanding how USB 3.0 is supposed to work with the Note 3. On both my work PC (Dell Optiplex 1020, 64-bit Windows 7 Enterprise) and my home PC (Dell XPS 8500, 64-bit Windows 7 Professional), whenever I connect the Note, a popup comes up saying the following:
"This device can perform faster
This SAMSUNG Mobile USB Composite Device can transfer information if you connect it to a Super Speed USB 3.0 port."
1. The ports being used on both computers are the blue USB ports with the USB logo that has the SS. Those ARE the 3.0 ports, aren't they?
2. I'm definitely using USB 3.0 cables (the 2-part connector), not a regular micro USB cable.
On the Note itself, when I click on the USB options, it gives me the option of enabling "USB 3.0" for data transfer, but when I do, it tells me that it's only temporary and will turn itself off after 10 minutes since it interferes with wifi.
So what's the deal here?
Is USB 3.0 broken, or is it strictly an on-demand feature? If the latter, how does this impact the charge rate? Does just using a USB 3.0 cable provide the faster charging rate or if the USB 3.0 capability on the phone is not active, does the charge rate drop down?
Thanks in advance.
I believe its a on demand thing. My computer does the same thing.

I've never had this issue. I plug mine in and it automatically reads it as 3.0.

Hi all,
I was wondering if anyone knew of a USB Y cable (with two male usb plugs converging into one female usb port) that could allow quick charge and data transfer so it could be used with Android auto? Both male usb plugs would need to be able to transfer data into the female usb port in order for this to work.

I guess this wouldn't work and might also damage the head unit, but I'm no engineer.
If I were adventurous enough to risk frying my head unit and/or phone, I would follow this
http://www.instructables.com/id/Add...-hub/step3/Cut-the-VCC-wire-of-the-USB-cable/
and connect the output of the quick charge car adapter instead of the external charger.
Then would cut the Vcc wire directed to the head unit.
I don't know if the main hub cable (the one which normally goes to the PC) has to go to the phone or the head unit: who's the host in Android Auto? I'm inclined to think it's the head unit, since the phone connects in mtp mode. So my first guess is main hub cable to head unit, quick charge adapter connected like in the article, then big usb to micro usb cable to phone.
Maybe voltage higher than 5V would fry the hub, and maybe Android Auto connection is so picky (and it's picky, you know) that the hub circuitry wouldn't allow it. Who knows.
Again I'm no engineer and I'm scared to try
But I would buy a safe device tested for this use case, 10/10 :laugh:

Use a usb y, but don't short the data pins to send it to high charge/current mode. You won't necessarily hurt the hu but you'll never connect to AA, the phone must detect the shorted pins to enter high charge mode. Which means the phone can't talk on the data wires. I find a 2a charger running at 1a plus the hu's usb keeps just ahead of the power usage.

Unfortunately, you can't have quick charge (2.0) and data transfer at the same time (at least with my Galaxy note 4). On a standard USB cable, you have 4 wires, two for data, two for power. On my GN4, the data pair communicate with the quick charger (I'm not sure exactly what the communication is, I remember reading somewhere it used the data pairs to communicate voltage, etc...).
Now, what I did do, was make my own data cable using 2 male type A adapters and connecting it all up to a a male microUSB end(Data pair is only connected to 1 of the type A male ends, I can't remember if I wired up the power in parallel). My AA head unit puts out less amps than my car charger, so even though I'm not getting quick charge speeds, I'm getting a bit more amps to charge with. So, one male end goes to my charger, one end goes to my head unit. I've been using it like this for over a year with no issues.
How much better is it than charging while connected to the AA head unit? Not sure. I'd rather have more amps than not enough.
Just buy a y. Cheaper and safer than self making.

Do you have a link? Can't seem to find anything that I think would work.

Hi,
I want to clarify some aspects:
1) Qualcomm's Quick Charge doesn't work when the USB is in use for data.
2) Quick Charge requires a certified adapter (as it's an active function).
3) USB power can charge the device, however very slow... in fact with AA the device consumes battery when running.
So, my question is:
- Increasing the USB power current with an Y cable the device can be charged more quickly?
- And if this is true: the Y cable needs to block the current from the dta USB port of the car?
I like to comment these topics.
Whenever I connect my Phone to my Laptop(Matebook X Pro), it quick charges my phone. (connection via usb c to usb c)
Is there a way I can stop that from happening and my phone leeching the battery from laptop so fast? OR stop charging it all together
Because usually I only connect my phone to laptop for roms and rooting and today for Android Q. I would charge my phone before doing these things hence I don't need my phone to suck out from laptop during this. I wonder if there is a way to reduce how much power the laptop is outputting. or turn it off all together
Besides, I have a powerbank for both my laptop and phone so if I am out and about, I'd charge the phone from the battery, it's less efficient to send it from battery to laptop to phone.
You'll probably need a custom kernel with special settings for that, as they usually try to speedup the charging instead, but I recall some bugged kernel/ROM versions (for another device that was; the Nexus 6P) which prevented fast-charging when not using an official QC adapter (like connecting it to the charge USB-port of your laptop; and that kinda sounds like what you're after). Many modern laptops have special charger-ports, sometimes even with QC support, so did you try another USB-port to see if perhaps charges slower ?

You see, when I'm out and about I only carry usb c to USB c cable so I can't check other ports. Both of the USB C ports are USB PD :/

Use a cheap legacy micro usb cable plus type c adapter. Since its hard to find bad quality usb c cable. It wont pass high current to your phone. Bad quality cable usually have very thin wire..
First it must be USB type c to USB A. 3.0
What USB standard nobody seems to know. For sure but most tell me its a USB 3.0 At the A end.
And USB Type C at the other end.
Next we need to know what is required in the cable to support Dex.
Next we need to know what is required to support Samsung Fast Charge standard. I hear its not the same as Quick Charge.
Is there any cable out there that does all these things.
I know the cable that comes with the phone does not do this.
i.e. I fails in the USB transfer speed dept.
In short.
Dex compatible,
Fast Charge compatible. As per this link we only need Fast Charge 2.0
But I wonder why does Samsung Claim to use its own standard. i.e. what is the diffirence between the Samsung standard and QC standard.
https://www.qualcomm.com/media/documents/files/quick-charge-device-list.pdf
USB 3.0 Standard compatible for high speed data transfer.
(They say if the USB A port is blue and has more than 4 pads it will work).
Ps: So far I have figured that my wifes One Plus 6 cable does all these jobs.
Answering my own question.
Got to amazon.
Search using this text usb type c to usb a 3.1
I got an amazon Basic from the search the USB A port is blue in color an indication that it is 3.0 It does everything Dex, fast speed transfer and fast charge.
Glad that you managed to get your cable. But for future reference any standard USB A 3.0 - Type - C charging cable will be good. However beware of multi-plug to USB A 3.0 cables as they don't have the best charging speeds, unless you have a high wattage power supply.
I'm using a nice quality INIU cable, has nice quality braided cover, a led for dark car charging, to see cable.
