Is 30MB/s the maximum file transfer speed to a PC from a Pixel 6? I think this is USB 2.0 maximum speed. Shouldn't it be more for USB 3.1? I tested writing to the Pixel 6 and reading data from the Pixel 6 on different USB 3.0 and USB-C and Thunderbolt ports.
Edit: I used for the test the original USB Pixel 6 charging cable and some other USB-C cables made intentionally for charging.

What is the speed if you use the Pixel 6 charging cable to transfer?
I also saw that when using the cable coming with pixel 6 speed is for usb 2.0 connection and indeed the connection is usb 2.0. Usually cables optimized for high wattage usb power delivery are usb 2.0 cables. Maybe if you use usb 3.0 cable optimized for data transfer speeds will be much higher.
Test it with different cable's. Do you use the original charging cable that comes with your pixel?
So all of you have higher speeds? What transfer rate should be possible on an USB 3.1 port with the pixel 6? Yes, I used the original Pixel 6 cabel. @neptun2 Thanks for the hint. I'll check if I can find a high speed cable which is not design for high power charging.

Since the Atrix charges extremely slow via regular USB 2.0 port, I was wondering if something like this might help?
http://www.amazon.com/StarTech-USB2HABMY6-Cable-External-Drive/dp/tech-data/B003HHK58U
The problem with USB 2.0 is that it's only 500mA while the wall charger is 850mA. With this, I would assume we'd get a full 1A.
Has anyone ever tried something like this? I'd like to know if it works.
A trickle charge is always better for battery life but if a quick charge is what you are looking for then you can try but not sure if it will give you any more power because of the phone itself. See Below.
"The USB 1.x and 2.0 specifications provide a 5 V supply on a single wire from which connected USB devices may draw power. The specification provides for no more than 5.25 V and no less than 4.75 V (5 V±5%) between the positive and negative bus power lines. For USB 2.0 the voltage supplied by low-powered hub ports is 4.4 V to 5.25 V.
A unit load is defined as 100 mA in USB 2.0, and was raised to 150 mA in USB 3.0. A maximum of 5 unit loads (500 mA) can be drawn from a port in USB 2.0, which was raised to 6 (900 mA) in USB 3.0. There are two types of devices: low-power and high-power. Low-power devices draw at most 1 unit load, with minimum operating voltage of 4.4 V in USB 2.0, and 4 V in USB 3.0. High-power devices draw the maximum number of unit loads supported by the standard. All devices default as low-power but the device's software may request high-power as long as the power is available on the providing bus.
Some devices like high-speed external disk drives may require more than 500 mA of current and therefore cannot be powered from one USB 2.0 port. Such devices usually come with Y-shaped cable that has two USB connectors to be inserted into a computer. With such a cable a device can draw power from two USB ports simultaneously."

Already covered multiple times!
Do some research. USB 3.0 has been out for a long time, and does supply up to 900mA as was said in the 1st response. It's also a powered USB port, where 2.0 is not!

I've actually searched quite a lot before posting and found nothing even related to this. Sure, people talked a lot about the difference between the wall charger and a regular USB port. However, my question was specific to USB 2.0 the cable in question.
Either way, thanks for your input.
@CaelanT Good luck finding a Usb3 micro connection that fits a usb2 micro connection. Not to mention atrix would put it on usb2 mode if you could.

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

For charging a phone it does not matter if its a USB 2.0 or USB 3.0 Those things only matter for data transfer.. cos the transfer rate depends on which usb connection you are using.
For wireless charging, the USB 2.0 charger is it. There is no 3.0 powerbank... cos technically it means nothing. Even if you see one in the description of any power bank.. it doesnt do any good.

Just as he has stated usb 3.0 just separates the power and the data between 2 connections instead of over the same connection. That is why you can plug a micro usb into half of the charge port and it works fine.
As for a battery - I prefer slim style that fits in a pocket and I got the Motorola 4000mAh battery about 1-2 years ago on a dailydeal for $20. Built in micro usb cable + usb port means it can charge anything.

Hi there !
I was wondering what is the benefit of a USBC-USBC vs USBC-USB3 when connecring to a PC ?
Will it charge faster ? Will it transfer faster ?
Thank you my friends good evening !
the data transfer works with my type-c laptop and xzp but don't know about the charging speed and voltage.
It would work on USB 3.0
XZP supports USB3.1 gen1, so you will get 5Gbps connection speed if you use a USB3.0 cable, no matter it is USB-A or USB-C. And if you have PD charger, you can use USB-C to USB-C for charging, XZP supports PD.
I just bought this: https://www.amazon.com/dp/B07H2ZS1B5/
It has HDMI, three USB 3 ports, Ethernet, and Power Delivery. At $40, it was the least expensive such item I could find. It appears to be well built. The housing is aluminum. The adapter is very small and slim.
The HDMI seemed to be a bit finicky with various HDMI cables, but once connected, screen mirroring and Dex worked fine on my TV. All three USB ports worked. I didn't test transfer speeds yet. Ethernet worked via DHCP upon plugging in a cable. No drivers were required for anything.
As for the Power Delivery, I also bought this: https://www.amazon.com/dp/B07FCFCRX6/
When using a good-quality USB-C to USB-C cable, the Anker supply charges the tablet at high speed. Using the USB-A to USB-C cable that came with the S4, both the Anker and the OEM charger charged at slow speed.
You don't need PD to use any of the ports, unless you plug something into the USB that takes a lot of current (like some hard drives).
The only port missing, for more versatility, is VGA. I looked at several adapters that included VGA, but both the size and price were significantly larger.
The attached USB-C cable is about 6 inches long, including the plug. There is enough length for the adapter to lay on the table in use. The adapter weighs very little, so the weight of the attached devices and cables are all that will hold it down.
I am pleased with both items that I purchased. The links I provided have no referrals. I bought these items with my own money, and get nothing by recommending them.
I haven't tried the adapter with my Note 9 yet, but see no reason it won't work just as well with the phone.
I just did a quick benchmark on the USB ports. Since I had previous results to compare against, I did the testing on my laptop.
Using Atto Benchmark and a Samsung 500 GB SSD in an external enclosure, I got maximum read/write speeds through the new hub of about 43 MB/s (344 Mb/s). The previous speeds with the SSD connected directly to the laptop were around 450 MB/S (3600 Mb/s). Quite a difference.
Although the hub presents a serious bottleneck, the obtained speeds are still not bad for USB 2. It's just not USB 3 speeds. For what I am likely to use this hub/adapter for, this shouldn't be much of an issue.
Hi! thanks for your suggestion. Did you find any better (although more expensive) product? A plus would be usb 3.0 and Dex hdmi support
There were several more expensive units listed on Amazon. I only purchased this one to try. This one does Dex over HDMI, as I mentioned.
This looks pretty slick! How does the ethernet connection work with the S4?
Does that charge work better than Samsung's? Because with my USB-C hub and Samsung charger the charge decreases with time.
